Abstract
A method for tire force reserve estimation is applicable to a vehicle. In the method, vehicle motion information including the longitudinal acceleration, the lateral acceleration, the change of the tire rotation angle at different times, the change of the yaw at different times, the steering angle of the steering tires, etc. is continuously detected, for estimating the current normal force, the current longitudinal force and the current lateral force of each of the tires. Finally, the current normal force, the current longitudinal force, the current lateral force and the coefficient of friction of the road relative to the tires are applied to estimate the longitudinal tire force reserve and the lateral tire force reserve.
