The present disclosure relates to a vehicle control method, device, and vehicle, and relates to the field of vehicle control. The method includes: acquiring slip rates of at least two driving wheels of the vehicle, determining a first number of non-slip wheels according to the slip rates, and Control the torques of at least two driving wheels according to the first quantity, repeat the steps of obtaining the slip ratio of the at least two driving wheels of the vehicle to determine the first number of non-slip wheels according to the slip ratio according to the preset control cycle, and according to the first quantity, A number of steps to control the torque of at least two driven wheels until a preset exit condition is met. The present disclosure can stabilize the driving direction of the vehicle under the premise of ensuring the acceleration performance of the vehicle, effectively avoid the skidding of the vehicle, enhance the stability and safety of the vehicle, and improve the driving experience of the user.
Description
technical field [0001] The present disclosure relates to the field of vehicle control, in particular, to a vehicle control method, device and vehicle. Background technique [0002] As the number of automobiles in our country continues to increase, people's requirements for the stability and safety of automobiles are also getting higher and higher. When the vehicle needs to increase the speed during the driving process, the vehicle will increase the driving force (that is, increase the torque on the driving wheels) to increase the wheel speed of the driving wheels, so as to achieve the purpose of increasing the vehicle speed. If the wheel speed of the driving wheels is too fast, there may be a problem of slipping of the driving wheels, which will easily cause the vehicle to slip, deviate from the original direction, etc., and even cause traffic accidents, which will reduce the safety and stability of the vehicle, and will affect the safety of the vehicle. The user's driving ...
