Zusammenfassung:An estimating method of tire grip allowance is used to estimate the tire grip allowance of a vehicle. The estimating method of tire grip allowance is to continuously detect the dynamic information of vehicle, including the longitudinal acceleration, the lateral acceleration, the change of wheel rotation angle at different times, the change of yaw angle at different times, the steering angle of the steering wheel, etc., so as to estimate the current normal force, current longitudinal force, and current lateral force of each wheel one by one. Finally, the current normal force, the road friction coefficient of the tire relative to the road, the current longitudinal force, and the current lateral force are applied to obtain a longitudinal grip allowance and a lateral grip allowance of each tire.
