8 month 12 Japan , BAIC held “ Altitude difference of 10000 meters 960 Ten thousand square kilometers Beijing X7 Challenge the limit ” The long-distance survey of the activity was carried out in Bayin wendur desert in Bayannur . In this testing session , Test team and guests drive Beijing X7 Desert high temperature experiments were carried out respectively 、 Gobi road driving 、100km/h High speed intelligent adaptive cruise control 3 Challenges .
Bayannur is located on the Bank of Hetao River, adjacent to the Yellow River , Gobi Yadan 、 The desert 、 Grassland and other landforms coexist , At the same time, the temperature difference between day and night is also very large , The maximum temperature of Gobi and desert during the day is even closer 50 Centigrade . And in this challenge , Although the surface temperature of the desert was close to 70 Centigrade , But Beijing X7 With excellent heat dissipation performance and stable power output performance , Completed the long-time driving in the desert section .
Desert heat challenge ： Driving in the hot desert is a great challenge to the heat dissipation efficiency of vehicles , And Beijing X7 rely on 4710mm The length of the car body , And 1892mm Body width , It provides sufficient space for the arrangement of heat dissipation pipelines in the engine compartment , This reduces the amount of coolant 、 turbine 、 Interference between cooling pipelines of air conditioning and other components , So as to improve the overall heat dissipation efficiency .
meanwhile , The special reason of desert terrain also makes the road more soft , Thus, it is easy to cause the wheel to spin or the wheel to sink , But Beijing X7 On board 1.5T Turbocharged engine +7 Power assembly of high speed wet double clutch transmission , It can maintain an appropriate speed to maintain the continuous power output of the engine , So it's easier to drive in the desert .
Gobi Road Driving Challenge ： The Gobi road becomes harder than before , Accompanied by gravel 、 Complex road conditions such as cracks and gullies , This also has a greater impact on the vehicle suspension than the loose sand road , At the same time, the splashing rubble hit the chassis of the vehicle .
Beijing X7 Thanks to the front of the car H Type guard 、 Large area front suspension subframe 、 The middle guard plate of the chassis effectively protects the chassis harness, etc , It can be protected from sand and stone . meanwhile , Beijing X7 The body is also made of more than 67% High strength steel 、14% Super strong body made of hot formed steel , This makes the vehicle in the severely bumpy Gobi 、 No deformation, distortion and abnormal noise when driving on non paved roads .
Beijing X7 It also uses the former McPherson 、 Rear multi link independent suspension system , It can give consideration to comfort and handling stability , meanwhile 2800mm The super long wheelbase makes Beijing X7 The longitudinal stability of the is excellent , In the sand layer with low adhesion , It can effectively reduce the slight swing of the rear of the vehicle during steering , The continuous ups and downs on the Gobi road can be easily passed , This makes the test team more confident about the next high-intensity challenges .
Paved roads challenge intelligent adaptive cruise system ： Then Beijing X7 Will continue the journey all the way west , At this time, you have switched to the paved road , There will be 100km Autopilot （L2 level ） The challenge of . In fact, it can be used continuously for such a long distance L2 In the case of automatic driving , Each of them ADAS The reliability of driving assistance will face great challenges .
It's worth mentioning , Beijing X7 Equipped with millimeter wave radar , It can not only identify the vehicles in front of the lane , It can also monitor the status of surrounding vehicles , In case of congestion and other vehicles , Braking in time can effectively reduce the risk of traffic accidents .
And in the whole process , There will also be curves with different curvature on the road , Thanks to the on-board network, high-speed assistance and front windscreen monocular camera , Beijing X7 It can predict the large curve of Expressway according to the map . In high-speed curves with large radians , The monocular camera keeps an eye on the lane line , Keep the vehicle running normally in the lane , Further improved L2 And the ease of active driving .
Finally, the test team and guests successfully completed this project in Bayannur 3 After the big challenge , Beijing X7 It's going to move on , Will successively reach the Turpan Basin with the lowest surface elevation 、 Everest base camp , Experience extreme cold with an altitude difference of up to 10000 meters 、 Extremely hot 、 Extremely high “ Three poles ” test .
