Abstract

The invention provides an antiskid control method and device, and the method comprises the steps: obtaining the angular speed of a steering wheel of a vehicle; according to the angular velocity of thesteering wheel, determining the angular acceleration of the vehicle steering wheel; determining a target slip rate according to the angular acceleration; and adjusting the wheel angular speed of thevehicle according to the target slip rate. According to the method, the target slip rate is further determined through the obtained steering wheel angular speed of the vehicle according to the steering wheel angular speed and the angular acceleration, then the wheel angular speed of the vehicle is adjusted through the target slip rate, anti-skid control can be conducted according to different vehicle driving modes, the anti-skid purpose is achieved, and the vehicle driving stability is improved.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular, to an anti-skid control method and device. Background technique [0002] With the current driving environment becoming more and more complex, the requirements for driving safety are also constantly increasing. For example, when there is snow, ice, etc. on the road, or when accelerating rapidly, the tires are prone to skidding. [0003] At present, many vehicles are standard equipped with anti-lock brake system (Antilock brake system, ABS), electronic brake force distribution system (Electronic Brakeforce Distribution, EBD), traction control system (Traction Control System, TCS), body electronic stability System (Electronic Stability Program, ESP). In the case of vehicle deviation or dangerous working conditions, the above-mentioned auxiliary system can actively intervene in the driving mode and adjust the vehicle's driving trajectory to achieve the purpose of wheel sli...
