SYSTEM FOR WHEEL SPEED CORRECTION OF VEHICLE AND METHOD THEREOF

摘要

A wheel speed correction apparatus and a method of vehicles are provided to detect the actual car speed to wheel and to utilize the speed for the posture control of the vehicles. A wheel speed correction method of vehicles comprises following steps: a step which detects a wheel angular velocity from a vehicle speed sensor and detects the tire pressure of each wheel from the pneumatic pressure detection unit; a step which calculates the volume of each wheel tire from the relation of the tire pressure and volume change; a step which calculates the strain angle according to the weight transfer; a step which calculates the radius change amount of tire; and a step which calculates the actual car speed for each wheel and applies the speed the chassis control.
