Patent ID: 8290676

Claim:
An apparatus for controlling a vehicle brake that is adapted to exert a braking force in response to an actuation setpoint, the vehicle brake including a brake actuator, the apparatus comprising: an input for receiving a braking setpoint; an input for receiving a measured torque representing a measurement of the torque generated by the brake; a setpoint calculation device operative to calculate a nominal actuation setpoint for the brake actuator on the basis of the braking setpoint, taking account of all components of the breaking setpoint; a correction calculation device operative to calculate a correction for the nominal actuation setpoint on the basis of the braking setpoint and of the measured torque, and taking account only of variations at low frequency in the braking setpoint; an output delivering the sum of the nominal actuation setpoint plus the correction as a corrected actuation setpoint for the brake actuator; and wherein said brake actuator is actuated in accordance with the corrected actuation setpoint.
