Claim 5:
6. A control device for controlling a vehicle brake, the brake comprising an electromechanical actuator which includes an electric motor,
wherein the control device is configured to control the electromechanical actuator from the temperature of the electric motor of the actuator, wherein the temperature of the motor is estimated from the motor constant and the ohmic resistance of the motor,
wherein:
the control device is configured to determine a first temperature corrective coefficient of the motor, on the basis of a first function which is representative of a ratio of an angular speed of the motor to the supply current of the motor as a function of the supply voltage of the motor, and/or
the control device is configured to determine a second temperature corrective coefficient of the motor, on the basis of a second function which is representative of a ratio of the ohmic resistance of the motor to the motor constant as a function of the temperature of the motor.
