  • Publication number: 20180236974
    Abstract: An actuator for an electric parking brake, EPB, is described. The actuator comprises a motor configured to actuate an actuating member of the EPB, as well as a reception interface configured to receive an enablement code. An enablement code is assigned to the EPB actuator which individualizes the EPB actuator against other EPB actuators. The actuator further comprises an evaluation unit configured to verify the received enablement code on the basis of the enablement code allocated to the EPB actuator and to enable a control of the motor in case of a positively verified enablement code. There is further provided a control device for the EPB actuator, an electric parking brake and a vehicle having the EPB actuator and corresponding operating methods.

    Abstract: A system and a method for preventing a vehicle from rolling away are described. According to one method aspect, in the case of a vehicle equipped with several EPB actuators, the activation of only one of these EPB actuators takes place if in the case of a road inclination lying below a threshold value the vehicle begins to roll away from the stationary state.

  • Patent number: 9205789
    Abstract: A method for avoiding error messages due to maintenance work on a vehicle, which are generated by a monitoring unit if one or multiple operating parameters of a monitored vehicle system are outside of a predefined, admissible value range. Accordingly, the general driving operation is monitored with the aid of a vehicle's own sensor system with respect to a maintenance state and, if a maintenance state is established, the admissible value range be automatically extended or at least one operating parameter is ignored during monitoring.

  • Patent number: 8489301
    Abstract: A device for controlling the brake pressure in a hydraulic brake system with the aid of a pressure-limiting valve that limits the brake pressure to a predefined threshold value, and to that end is driven by an electronic device in accordance with a valve characteristic curve. The setting accuracy can be improved considerably if an estimating unit for estimating the brake pressure, a sensor system for measuring the brake pressure, a unit for determining a pressure difference between the measured brake pressure and the estimated brake pressure, as well as a controller unit which drives the pressure-limiting valve as a function of the pressure difference are provided.

  • Patent number: 7407463
    Abstract: In a method and system for controlling a braking system, equipped with an electric parking brake, for a motor vehicle, the electric parking brake is released in response to an identification of a moving-off operation. A release instant of the electric parking brake is defined in dependence on at least one measured parameter of a clutch engagement operation. In comparison with a method and system in which, for example, the electric parking brake is released in dependence on the actuation of the accelerator by a driver, the method and system permit a more precise coordination of the deactivation of the electric parking brake with the clutch engagement operation, and thus with the moving-off operation of the vehicle, particularly in the case of a vehicle equipped with a manual transmission.

  • Patent number: 7401872
    Abstract: The present invention provides a method and a system for controlling a braking equipment of a motor vehicle in order to activate the braking equipment at a standstill of the motor vehicle such that braking forces are built up which are necessary to keep the motor vehicle in a state of standstill. To this end it is established on the basis of vehicle movements whether the vehicle is at a standstill. If vehicle movements are detected that cannot occur during driving modes of the motor vehicle, the motor vehicle is in a state of standstill. Subsequently, the braking equipment, and in particular a holding brake mechanism included in the braking equipment, are activated. In order to provide braking forces keeping the motor vehicle at a standstill also when it is on a slope, the braking equipment, and in particular the holding brake mechanism, are controlled in response of the vehicle inclination present in the state of standstill.

  • Patent number: 7338137
    Abstract: The present invention provides driveaway assistance for a motor vehicle having braking equipment which, in the standstill condition of the motor vehicle, automatically or under the control of a vehicle driver summons up braking forces needed for the standstill condition. To assist start-up (driveaway) of the motor vehicle through a reduction of the braking forces generated in the standstill condition, a driveaway request or a vehicle driver is determined when defined conditions, which are to be met for driveaway of the motor vehicle, exist in the standstill condition. Once a driveaway request has been recognized, the operating state of the motor vehicle is checked until an operating condition required for driveaway exists. Once such an operating condition is reached, the braking equipment of the motor vehicle is controlled in such a way that its braking forces generated in the standstill condition are reduced to allow driveaway of the vehicle.

  • Patent number: 7227324
    Abstract: A method for controlling an electrically actuable parking brake is described. In this method the cutoff current of the electric motor is varied to compensate for example for changes in the application force associated with aging or wear or for changes in the application force due to changes in the resistance and/or temperature of an electric motor.
