One 、 The connotation of Internet connected automatic driving

Automatic driving is an intelligent vehicle as a vehicle 、 Core application of networking development , It's also the Internet of vehicles 、 The core application service of intelligent transportation industry development .

On a technical level , Currently there are There are two different implementation paths: single vehicle intelligent automatic driving and network connected automatic driving .

Single vehicle intelligent automatic driving mainly depends on the vehicle's own vision 、 Millimeter wave radar 、 Sensors such as lidar are used to sense the environment 、 Computing decisions and controlling execution .

Environmental perception completes the detection and positioning of the surrounding environment through on-board sensors . On the one hand, the sensor data are analyzed and processed , Realize target recognition ; On the other hand, conduct behavior prediction and global path planning 、 Local path planning and real-time action planning , Determine the current and future trajectory of the vehicle .

Control execution mainly includes vehicle motion control and human-computer interaction , Determine each actuator such as motor 、 throttle 、 Braking and other control signals .

At present, single vehicle intelligent automatic driving is in environmental perception 、 There are different degrees of technical bottlenecks in many links of computing decision-making and control execution , In the application process, there are also various failure problems , Therefore, on the one hand, it is necessary to continuously strengthen the perception of bicycle intelligence 、 Decision making and control capability ; On the other hand, we also hope to introduce different technical means to make up for it .

Internet connected automatic driving is based on the existing single vehicle intelligent automatic driving , The aim is to integrate “ people - vehicle - road - cloud ” The elements of traffic participation are organically linked , Expand and assist the application of single vehicle intelligent automatic driving in environmental perception 、 Ability upgrade in computing decision making and control execution , Accelerate the maturity of automatic driving application .

In the context of environmental awareness , Support the vehicle to obtain more information than the single vehicle intelligent perception , For example, non line of sight perception or solving problems that are easy to be affected by harsh environment ;

Collaboration in computing and decision making , Add cars and cars 、 Systematic decision making between car and road , For example, solve vehicle priority management 、 Traffic intersection optimization control and so on ;

Cooperate in the control and execution process , Intervene in vehicle driving behavior , For example, remote control vehicle rescue, etc .

meanwhile , The development of Internet connected automatic driving will also drive “ people - vehicle - road - cloud ” Construction and improvement of new infrastructure system for collaborative vehicle networking , help 5G、 Application and promotion of information and communication technologies such as artificial intelligence in vertical industries , Promote the development of new models and new business forms of automobile and transportation services .

Two 、 Requirements and typical applications of networked automatic driving

( One ) Development status of single vehicle intelligent automatic driving

1. The application of single vehicle intelligent automatic driving is not yet mature

According to the American Society of Automotive Engineers (SAE) The division of L0-L5 In terms of automatic driving level , At present, the intelligent automatic driving of single vehicle is in its infancy L2-L3 Landing development stage of grade , Market penetration and application scale are still small , Advanced auxiliary driving system functions (Advanced Driver Assistance Systems,ADAS) Still the main force . Gaogong Intelligent Automobile Research Institute 《2020 year 1-2 Monthly new passenger car insurance volume ADAS Market data report 》 Put forward , Domestic independent and joint venture brands launch new cars ADAS The carrying rate is 28.15%.《 Intelligent network connected vehicle technology roadmap 2.0》 Put forward , To 2025 year ,L2 and L3 Considerable part of automatic driving (PA ) And conditional autopilot (CA) The proportion of car sales will exceed 50%, Highly autonomous (HA, amount to L4) Start entering the market . From the R & D Progress of various automobile enterprises ,2018 BMW in 、 Volvo 、 audi 、 General motors and others have been launched one after another L2 Class a autonomous driving application ;2020-2022 The year is planned to be launched by various car enterprises L3 Time of automatic driving vehicle , But there are only a few L2.5、L2.99 Conceptual application of automatic driving , On the one hand, limited by L3 Improvement of laws and regulations for automatic driving vehicles , On the other hand, it is limited by technical implementation . Comprehensive analysis of , From the perspective of Technological Development , At present, the technical realization ability of single vehicle intelligent automatic driving is L2-L3, But it is limited by the scene , For example, it needs to be on the highway 、 Urban trunk roads with standardized and clear road signs, etc ; From the perspective of industrial application ,L2 And the following ADAS The application still maintains a low penetration level ,L3 And above autopilot applications are still mainly experimental and regional demonstration ,L4 And higher level automatic driving applications take longer .

2. There are still many risks in intelligent and automatic driving of single vehicle

At present, there are a lot of commercial mass production ADAS The function still has the risk of insufficient coping ability and failure under specific scenarios . Take automatic emergency braking as an example ,2019 American Automobile Association (AAA) To Chevrolet Malibu XL、 Honda accord 、 tesla Model 3 And Toyota Camry , On the one hand, it is found that the vehicle's coping ability is insufficient in scenes such as night or children's shuttle , Most of the models had collision ; On the other hand, it's an umbrella on a rainy day 、 A raincoat 、 Tunnel and other scenarios are easy to cause failure . Existing commercial ADAS The function is not yet able to cope with complex traffic conditions or severe weather conditions , The lack of perception is still the main reason . But under the condition that the driver is responsible for the whole driving process ,L2 And the following ADAS The application function is ready for commercial landing .

In terms of high-level automatic driving road test , The reliability of automatic driving and the ability to cope with challenging traffic scenes still need to be improved . from 2019 Annual California autopilot disengagement Report 《Autonomous Vehicle Disengagement Reports》 Look at ,36 Enterprises enter

Did the autopilot test , Google Waymo With 234 10000 km test mileage is far ahead , Its every 21273 There was a breakaway takeover , But by comparison, apples are every 189 There's going to be a breakaway takeover . From the reasons for leaving the takeover , The reliability of software and hardware system performance is a common problem faced by almost every testing enterprise ; Besides , Insufficient perception of sudden targets 、 The prediction ability of target motion behavior is insufficient 、 Decision time timeout and wrong trajectory generation 、 The error of traffic information identification is also the main problem .

Besides , Some commercial autonomous vehicles also have various types of accidents , There is a perceived failure 、 Failure of prediction and decision-making .2018 year 1 month , One in Los Angeles, USA Model S The fire truck that fails to detect the stop ahead in time due to the sudden lane change of the following vehicle , Failure to brake in time / Accident caused by deceleration , Lead to the discussion of its perceived failure .2016 year 2 month , A Lexus vehicle in California sensed that a bus was ready to pass behind , However, it is judged that there is not enough space on the road for buses to pass , It is assumed that the bus driver will slow down , The bus driver judged that Lexus would yield , Therefore, collision occurs , It shows the intelligent automatic driving of a single car in this kind of “ game ” It is difficult to accurately judge the intention of the surrounding traffic participants under the driving conditions , The challenge of collaborative decision-making is put forward .

( Two ) The challenge of single car intelligent automatic driving and the demand of Internet connection

1. The challenge of environment perception and the demand of networking

at present , Technical solution of single vehicle intelligent automatic driving , Visual sensors 、 Laser radar 、 Millimeter wave radar and infrared night vision 、 Mature sensors such as ultrasonic are the main product components .

The nominal technical indicators of various types of sensors continue to develop steadily , Continuously meet the needs of automatic driving , Gradually approaching the perception of human drivers , It has even surpassed some technical capabilities , For example, detection distance 200 Meters above 、 The comprehensive accuracy can reach centimeter level or even millimeter level . However, the reliability of various sensors , And the ability to respond to emergencies is still insufficient . One side , Vulnerable to occlusion 、 Adverse weather and other environmental conditions , Such as intersection 、 Tunnel entrance and exit, etc .

Networking through vehicle road collaboration 、 Car car collaboration , It can greatly expand the perception range of bicycles , And it's not restricted by occlusion , It allows the bike to discover the unknown ahead of time , Be able to deal with situations that are difficult to deal with in autopilot tests and accidents, such as the sudden entry of the target . Besides , Application of single vehicle intelligent automatic driving in target prediction 、 Driving intention “ game ” And so on .

Networking can directly give the state information of key results , For example, signal lamp status 、 Next action intention of surrounding vehicles 、 The best driving route under the current road conditions, etc , It reduces the complex calculation and processing process based on sensor information , And can accurately understand the intention of the surrounding traffic participants .

2. The challenges of computing decision-making and networking requirements

The main functions of computational decision can be divided into two categories , One is target recognition based on environment perception data , Deep neural network is the most widely used way in perception , It is also the computing task with the greatest demand for computing power consumption ; The second is the result of perception and the driving task of the vehicle , Give the route 、 Decision planning of vehicle movements .

On hardware , Computational decision-making is mainly based on CPU、GPU、DSP、AI chip 、MCU On the computing and processing platform with multi-core and heterogeneous distribution .

The contradiction between computing power and power consumption is an important bottleneck encountered by the single vehicle intelligent automatic driving computing and processing platform .

meanwhile , Because the traffic behavior is more between many participants “ game ”, In the decision-making and planning of path action , It is difficult to give the best solution for single vehicle intelligent automatic driving .

Network connection is expected to share the computing power consumption of bicycles , The global optimal driving strategy is given based on the cloud control platform .

In computing power , One is the networking as “ Super sensors ” Can directly give the perceived target results , The complex calculation and analysis process of sensor signal is omitted , Such as the judgment of traffic lights , This greatly reduces the computing power demand of the bicycle ; Second, we can use cloud computing 、 Edge computing, etc , It is expected to introduce the roadside calculation force into the road , For example, install a vision sensor on the roadside 、 Lidar and other sensors , Distribute the roadside perception results, etc .

In terms of driving strategy , In certain situations , Network connection can collect traffic participants within its scope , According to the purpose and state of all subjects , Give a global optimal solution , There is no need to pass “ Probe ” and “ game ” Give a decision plan , In the mine 、 port 、 Logistics and other non-public open roads have been verified and applied in specific scenarios .

3. Control execution challenges and networking needs

The control execution of single vehicle intelligent automatic driving is mainly based on the action command given by the calculation decision , Through the vehicle dynamics model and human-computer interface , To the motor 、 throttle 、 Brake and other actuators .

In terms of control execution , The coordination between automatic driving system and human driving is considered, and the reliability of vehicle control is also considered. 、 Security , Redundant control systems 、 High real-time response is the main technical requirement .

In terms of control execution, the network can provide remote control driving 、 The application mode of cooperative driving . For example, in some dangerous or unsuitable occasions for human access , Need to pass through 5G Remote control driving to operate the remote vehicle for operation , At present, it has been applied in unmanned mines and other occasions .

In terms of vehicle formation driving, etc , Information interaction is performed by means of the control of the front and rear vehicles , The rear vehicles can drive according to the unified command of the head vehicle , Reduce the perceived computing task load of rear vehicles .

Networking can separate vehicle control and execution from single vehicle , Help create a number of innovative application models .

( 3、 ... and ) Typical application of networked automatic driving

On the basis of single vehicle intelligent automatic driving , Introduction of networking technology , So that more cooperative automatic driving applications can be realized .

It is considered from the two dimensions of typical working conditions and collaborative links , The application scenario of networked automatic driving can be divided into a matrix .

Typical working conditions include various intersections 、 Expressway 、 Tunnel 、 Parking spaces 、 mine / Port and other relatively structured road environment , And general working condition environment . Collaborative link includes collaborative perception 、 Collaborative decision-making and collaborative control .

image-20210803105422977

The dependence of different application scenarios on Internet connection can be divided into two categories , One is the application scenario that requires network connection to be realized in the full working condition environment . For example, signal lamp 、 Information acquisition such as identification plate , In rainy, snowy and foggy weather with low visibility , Single vehicle sensing devices will be difficult to accurately identify , The above information can be obtained through the networked communication between the vehicle and the corresponding traffic infrastructure on the roadside ; More Than This , The digitization of signal lights and other information increases the possibility of dynamic adjustment , Make tidal Lane 、 Dynamic speed limit and other scenarios are easier to implement . secondly , Blind zone perception , The camera and lidar that can be carried by a single car have physical limits , The deployment of some roadside sensing devices can easily solve the visual blind spot of a single car , And the remote dynamic traffic event information can be 、 Send road information to vehicles . also , Group intelligence , Global path planning based on traffic information needs a powerful decision-making platform based on cloud , And distribute the planning results to the vehicles in the area , This can not be achieved by single vehicle intelligence , And the remote monitoring and takeover intervention of abnormal vehicles can be realized through network connection . The second is to realize more economical application scenarios through network connection . Such scenarios are also technically feasible , However, the implementation cost is too cumbersome and expensive , It is not conducive to the rapid popularization of applications . For example, typical urban working conditions such as intersections , In the process of identifying mixed traffic subjects , Bicycles need to pay a great deal of perceptual and computational overhead , And through roadside perception 、 Calculation 、 Deployment of communication and other equipment , It can achieve the large-scale effect of resource reuse . Another example is the tunnel 、 Location of closed spaces such as parking lots , With roadside communication equipment 、 Cellular communication base station 、 Edge computing server, etc , With the same accuracy , It can greatly reduce the single vehicle inertial navigation 、 The overhead of a series of complex fusion sensing algorithms such as radar .

at present , Relevant application scenarios of Internet connected automatic driving have also been carried out at home and abroad .

port 、 mine 、 Logistics parks and other closed scenes have become the first places to deploy commercial vehicles L4 Demonstration area for automatic driving .

Bosch 、 Mercedes Benz 、 Nokia and other partners , Demonstration of non-stop import based on smart infrastructure and edge computing in Ulm, Germany , Here's the picture 1 Shown . The project construction party shall install cameras on road lamp posts 、 Laser radar 、 Roadside communication equipment and MEC Edge computing server , Expand vehicle perception , Solve the visual recognition blind area of the vehicle's own perception equipment , Such as pedestrians blocked by trucks 、 Vehicles coming from the blind area 、 A bicycle approaching and changing lanes from the rear .

The system can collect the image data collected by the road end sensor , Combined with data collected by vehicle sensors , With the support of edge computing force , Combined with high-precision map , It can generate a vehicle surrounding environment model containing all the information of the current road conditions , And transmitted to the vehicle through network technology . After the implementation of the project , Autonomous vehicles can accurately find the traffic flow gap on the main road , It can seamlessly merge into the traffic flow of the main road without stopping .

Four 、 The challenge of networked automatic driving

Internet connected automatic driving has become a clear technical main line for the development of high-level automatic driving in China ,“ Internet connection ” It is an important way to strengthen the roadside infrastructure to enable the vehicle end “ The Conduit ”, It's also driving “ Smart cars ” And “ The way of wisdom ” Deep integration of supporting technology . But from the maturity of technology and industrial development , In depth support of Internet connection, automatic driving still faces technical integration 、 Infrastructure construction 、 And the difficulties and challenges in business operation mode .

The technical system of deep collaboration of Netcom still needs to be improved , The roadside infrastructure has not yet established the concept of functional safety level .

First, it is difficult to establish roadside message acceptance mechanism . At present , Vehicle factory 、 Component manufacturers and Internet companies generally believe that roadside sources can only be treated the same as on-board sensors , That is, autonomous vehicles cannot directly accept external information , The on-board sensor is still required to be combined with roadside information input , Fusion perception judgment , Roadside sensor as redundant source , To some extent, it can solve the problem of common cause failure . In the future, reliability level can be added to roadside messages to ensure the reliability of messages , for example , Daimler proposes to add vehicle safety integrity level to roadside transmission information or certification information (ASIL) Or safety integrity level (SIL) Information to ensure the credibility of the message .

Second, the reliability of transmission channel is difficult to guarantee . Need for network automatic driving 5G The network provides a lot of bandwidth 、 Ultra high reliability and low delay 、 Wide connection communication environment , But the quality of wireless channel is often blocked 、 scattering 、 Multipath fading and other factors have a greater impact , Lead to delay 、 It is difficult to guarantee the reliability of roadside message transmission .

Third, cross industry 、 Cross regional digital identity authentication has not been coordinated and unified . Cars and cars 、 Trust between car and road , It is a necessary condition for fully automatic driving relying on network technology , At present, the industry adopts PKI (PKI) The digital identity authentication mechanism of , For vehicular communication equipment 、 The roadside communication equipment issues legal digital certificates , Realize the identity authentication of communication process . From the perspective of industry and local management , Different industry authorities are needed 、 Establish a collaborative and unified digital identity authentication mechanism in different regions , Maintain the digital certificate trust relationship of collaborative mutual recognition .

Fourth, the definition of roadside function safety consistent with the vehicle end is not clear . Traditional automobile enterprises still have doubts about the willingness to deeply integrate the networking technology into the vehicle R & D iteration , The key is that the roadside infrastructure lacks the functional safety and expected functional safety system that matches the vehicle end , It is difficult to establish an accident responsibility identification mechanism for ICV . Based on functional safety and SOTIF The safety evaluation method of this project , Actively explore the functional level requirements and safety definition standards of roadside infrastructure , Or it will promote the deep integration of vehicle and road cooperation .

Infrastructure construction planning is not clear , Barriers to industrial data interoperability .

First, the participants are diversified , The construction and operation mode is not clear . Vehicle networking cross industry 、 The cross domain attribute determines the diversification of industrial participants , It directly leads to the fragmentation of construction and operation . At present, the government is wholly-owned / joint venture 、 Highway owners 、 Operators and other participants have their own advantages and disadvantages in construction and operation , However, they all face the problem of unclear operation mode , In the future, the business form and business model of the Internet of vehicles still need to be explored by the government and the industry .

Second, the scale of infrastructure investment is large , The construction planning path is not clear . Internet connected automatic driving relies on the leapfrog improvement of roadside infrastructure coverage and vehicle terminal penetration , But roadside infrastructure involves many kinds 、 The industry is widely distributed 、 Large scale of investment , There is uncertainty about the return on investment 、 Safety responsibility risk and other issues . At present, some cities or high-speed road sections are undergoing intelligent networking transformation , There is also a lack of unified engineering construction scheme and consideration of the overall layout of transportation . meanwhile , Vehicle terminal penetration 、 The density of roadside facilities is low , Can't support the whole time 、 All elements of road traffic information perception , It is difficult to support the landing of all kinds of autopilot applications .

Third, it is difficult to establish industrial ecology , We need to break down barriers to data connectivity . All kinds of infrastructure belong to different construction subjects , The data collected belong to different enterprises 、 Different authorities , There is bound to be information islands . Realize the interconnection of devices 、 Platform data exchange , On the one hand, it needs cross industry 、 Cross departmental coordination , Break the barriers of industry platform management ; On the other hand , It is urgent to improve the equipment communication interface 、 System platform interface 、 Standardization system for message consistency, etc .

The commercial operation mode of Internet connected automatic driving is still in the design and exploration stage , Supporting policies and regulations need to be improved . One is the lack of public service “ Killer level ” application . Networking applications are gradually oriented to traffic safety and efficiency scenarios , Prompt through early warning information 、 The speed of the car / Improve traffic efficiency by means of path guidance , However, passenger car users do not respond strongly to such businesses , Rigid demand unknown . Even for some relatively high-value Internet applications , Such as signal light information push 、 Intersection collision warning, etc , As the infrastructure deployment has not yet reached the urban scale coverage ,

Low penetration of vehicle terminal , Resulting in reduced user experience . Second, supporting policies and regulations need to be improved , Restrict the transformation of demonstration application to commercial operation . Networked automatic driving depends on the support of high-precision map and positioning , Both of them will be subject to the management and constraints of Surveying and mapping related laws and regulations , The map still needs to be further refined 、 Crowdsourcing mapping 、 original GPS Requirements of acquisition and other links . Besides , For autonomous taxis 、 Independent valet parking (AVP) And other scenarios with relatively clear business models , Supporting safety 、 Road traffic regulations still need to be improved . At present, Beijing 、 Shanghai 、 Guangzhou and other cities have opened trial operation areas for autonomous taxis , However, there is still a gap with the real commercial operation .
