Abstract

The invention discloses a control method and device for inhibiting the drastic change of the soaring rotating speed of driving wheels and a vehicle. The method comprises the steps that the state information of the driving wheels is obtained; it is determined that the driving wheels are soared according to the state information of the driving wheels; and based on the soared driving wheels, a powersource is controlled to output torque, so that the wheel speed of the driving wheels is matched with the wheel speed of driven wheels. According to the method, when the vehicle runs through a deceleration strip and a washboard road at a high speed, after the driving wheels are soared, the drastic change of the rotating speed of the driving wheels is inhibited and controlled, so that the impact ona transmission system in the scene can be reduced, and the service life of the transmission system is prolonged; and when the vehicle runs through the deceleration strip and the washboard road at a high speed, after the driving wheels are soared, inhibiting control is conducted on the suddenly-increased rotating speed of the driving wheels, false triggering of a traction control system (TCS) is reduced, and the service life of the traction control system is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle longitudinal dynamics control, in particular to a control method, device and vehicle for suppressing drastic changes in idling rotational speed of driving wheels. Background technique [0002] Traction Control System, referred to as TCS, also known as ASR or TRC. Its role is to make the car get the best traction in all driving conditions. The control device of the traction control system is a computer, which uses the computer to detect the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if it detects that the speed difference between the driving wheel and the non-driving wheel is too large, the computer immediately judges that the driving force is too large , to send a command signal to reduce the fuel supply of the engine, reduce the driving force, thereby reducing the slip rate of the driving wheel. The computer grasps the driver's steering inte...
