Abstract: Disclosed is a brake actuating unit for actuating a motor vehicle brake system of the ‘brake-by-wire’ type. The system includes a brake booster which is operable in response to the driver's wish both by a brake pedal and by an electronic control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. A master brake cylinder connected downstream of the brake booster, a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and due to which a resetting force acting on the brake pedal can be simulated in the ‘brake-by-wire’ operating mode independently of an actuation of the brake booster, and which can be enabled in the ‘brake-by-wire’ operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the ‘brake-by-wire’ operating mode. The pedal travel simulator (2) is enabled and disabled by electromechanical means (22, 25), electrohydraulic means (40, 47) or pneumatically operable means (96 to 98).

Abstract translation: 公开了一种用于致动“线控制动”型的机动车辆制动系统的制动器致动单元。 该系统包括一个制动助力器，该制动助力器可响应驾驶员由制动踏板和电子控制单元的愿望而操作。 提供了一种装置，用于以“线控制动”操作模式将制动踏板和制动助力器之间的力传递连接分离。 连接在制动助力器下游的主制动缸，用于检测驾驶员的减速请求的装置以及与制动踏板相互作用的踏板行程模拟器，并且可以在该刹车踏板上模拟作用在制动踏板上的复位力 独立于制动助力器的致动而与“制动”一起操作，并且当制动踏板和制动助力器之间的力传递连接被解耦时，它可以在“线控制动”操作模式下启用 并且可以在“线控”操作模式之外禁用。 脚踏行驶模拟器（2）通过机电装置（22,25），电动液压装置（40,47）或气动操作装置（96至98）启用和禁用。
