摘要

The anti-lock brake system includes a friction torque gradient calculation unit for calculating a gradient of a friction torque with respect to a slip velocity from a plurality of variables, and further includes a friction torque gradient calculation unit for calculating a friction torque gradient based on the friction torque gradient calculated by the friction torque gradient calculation unit Thereby controlling the brake force acting on the wheel. The friction torque gradient estimating unit will use a number of estimation methods. That is, a method of calculating the gradient of the friction torque from only the time series data relating to the wheel speed, a method of calculating the friction torque gradient from the time series data relating to the wheel deceleration similarly to the time series data or the brake torque relating to the physical quantity associated with the brake torque Method or a method of calculating a friction torque gradient from the micro gain which is obtained when the breaking force is excited to a small amount at the reaction frequency of the vehicle, wheel and road surface containing vibration system and which characterizes the vibration system. Furthermore, a method for determining a characteristic limit of the friction torque provided between the wheel and the road surface is described from the thus calculated friction torque gradient.
