Problems solved by technology

[0002] In the related technology, when the vehicle is running under the emergency braking condition of the separation road, the braking performance and stability of the vehicle cannot be considered
If you want to obtain higher braking performance, the stability of the vehicle will be reduced, and if you want to obtain higher stability, the braking performance of the vehicle will be reduced
[0003] In addition, for a vehicle with an automatic driving function, under the emergency braking condition of the separation road, the driver needs to be notified to control the vehicle artificially, which is less safe, and at the same time, the braking performance and stability of the vehicle cannot be considered

Abstract

The invention discloses a vehicle and an automatic driving method and device thereof. The automatic driving method includes the steps that under the working condition of split road surface emergency braking, the current brake pressure difference between a high-attachment-coefficient road surface side and a low-attachment-coefficient road surface side of the vehicle is acquired; current first transverse torque of the vehicle is acquired according to the brake temperature difference; second transverse torque needed by the vehicle is acquired according to state information of the vehicle; adjusting parameters on a steering wheel on the vehicle are acquired according to the first transverse torque and the second transverse torque; the adjusting parameters are sent to an electronic power-assisted steering system, so that the steering wheel is adjusted according to the adjusting parameters, wherein the adjusting parameters comprise the rotating angle and the rotating speed of the steering wheel. Thus, when the vehicle is under the working condition of split road surface emergency braking, the steering wheel of the vehicle can be automatically adjusted correspondingly, thus, on the premise of not affecting the braking performance of the vehicle, the stability of the vehicle is greatly improved, and meanwhile the safety of the vehicle with an automatic driving function is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle automatic driving method, a vehicle automatic driving device and a vehicle. Background technique [0002] In the related art, when the vehicle is running under the condition of emergency braking on a separated road surface, the braking performance and stability of the vehicle cannot be taken into account. If you want to obtain higher braking performance, the stability of the vehicle will be reduced, and if you want to obtain higher stability, the braking performance of the vehicle will be reduced. [0003] In addition, for a vehicle with an automatic driving function, under the emergency braking condition of the separation road, the driver needs to be notified to control the vehicle artificially, which is less safe, and at the same time, the braking performance and stability of the vehicle cannot be considered . Contents of the invention [0004] The present invent...
