  • Publication number: 20210031740
    Abstract: System (195) and method (300) for providing an extra torque from a motor (110) to a brake pedal (115). The system comprises a brake pedal (115) having an input rod; a motor (110); a sensor (125); and an electronic controller (130) configured to receive a velocity of the input rod of the brake pedal (115) from the sensor (125), determine a torque ratio based on the velocity, determine a differential stroke of the brake pedal (115), determine a torque offset based on the differential stroke, determine an extra torque based on the torque ratio and the torque offset, and control the motor (110) to apply the extra torque to the brake pedal (115).

  • Patent number: 10604131
    Abstract: Systems and methods for providing open loop motor control for an electromechanical brake when closed loop motor control fails. The method includes determining, with an electronic controller, whether a rotor position sensor or a current sensor is not operating correctly, generating, with the electronic controller, a generated control signal for controlling a permanent magnet synchronous machine, and activating, with the electronic controller, the permanent magnet synchronous machine using the generated control signal to generate a stator magnetic field to operate the rotor of the permanent magnet synchronous machine of the electromechanical brake.

  • Patent number: 9862363
    Abstract: In a method for setting a parking brake that has an electromechanical brake device having an electrical brake motor, the release time duration for displacing the electrical brake motor in the release direction is determined from the closing time duration in which the brake motor was previously displaced in the closing direction.

  • Patent number: 9272692
    Abstract: In a method for setting the clamping force, which is exerted by a parking brake, a portion of which clamping force is at least partially generated by an electromechanical braking device having an electric actuator, and another portion is additionally generated by an additional braking device, as needed, the actual force curve is determined and compared to a characteristic, defined force curve to determine the magnitude of the electromechanical clamping force to be supplied by the electric actuator. If the actual force curve corresponds to the characteristic force curve, then, in addition to the electromechanical clamping force, an additional clamping force of the additional braking device is also taken into account for obtaining the setpoint clamping force.

  • Patent number: 9114792
    Abstract: In a method for setting the clamping force exerted by a parking brake, which is generated at least partially by an electromechanical braking device and, if needed, in supplementary fashion by a hydraulic braking device, in the provision of the hydraulic clamping force, a boost pressure to be generated in the hydraulic braking device is increased with respect to a switch-off pressure at the switch-off time that corresponds to the hydraulic clamping force.
