First and second power transmission units are configured for selectively providing pressurized hydraulic fluid during a braking event. The first power transmission unit actuates a selected one of the front wheel brakes and a selected one of the rear wheel brakes. The second power transmission unit actuates the other one of the front wheel brakes and the other one of the rear wheel brakes. First and second electronic control units control the first and second power transmission units. A pair of rear brake motors selectively electrically actuate rear wheel brakes. Multiplex control of each of the pairs of front and rear wheel brakes is provided by an arrangement of first and second parallel valves for each wheel brake.

摘要： A brake apparatus includes a first processor configured to output a first control signal based on an output signal of a parking switch, a second processor, a first parking brake driver configured to drive a first parking brake motor and a second parking brake motor based on the first control signal, and a second parking brake driver. The first processor transmits a first periodic signal to the parking switch during a normal operation of the first processor. The parking switch transmits a second periodic signal to the second processor in response to the first periodic signal received from the first processor. The second processor does not output the second control signal in response to the second periodic signal, and outputs a second control signal in response to not receiving the second periodic signal. The second parking brake driver drives the second parking brake motor based on the second control signal.

摘要： A method for securing a motor vehicle with at least one wheel brake during an automated driving maneuver includes, in order to carry out the automated driving maneuver, setting a hydraulic pressure at the wheel brake in order to generate a defined braking force large enough to securely arrest the motor vehicle during the execution of the automated driving maneuver. The method further includes keeping the hydraulic pressure which is set at the wheel brake essentially constant during the execution of the automated driving maneuver. The method may be implemented in a device.
