摘要： A wheel-specific, electrohydraulic brake actuator for controlling the brake pressure of a connectible wheel brake of a motor vehicle in a slip-dependent manner. A method for controlling a wheel-specific, electrohydraulic brake actuator as well as an electronically slip-controllable vehicle brake system using wheel-specific, electrohydraulic brake actuators, are also described. In the brake actuator, a pressure channel connects the brake pressure generator directly to the wheel connection.

摘要： A method for operating a regenerative braking system of a vehicle by activating at least one motor employable in generator mode taking into consideration a first information with regard to a requested setpoint total braking torque and a second information with regard to an available generator braking torque which is maximally executable by the at least one motor employable in generator mode, if the setpoint total braking torque exceeds a threshold value and/or a piece of warning information regarding a transition to a backup level that is potentially imminent or has occurred of the regenerative braking system, even if the setpoint total braking torque is less than or equal to the maximally executable available generator braking torque, sufficient brake fluid is transferred via at least one hydraulic actuator to a wheel brake cylinder of the regenerative braking system that an air gap of the particular wheel brake cylinder is closed.

摘要： A vehicle braking system includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, a brake pressure generator for brake-by-wire braking, and a pedal feel simulator. In response to detecting impending wheel lock-up, a controller conducts an anti-lock braking routine during which the controller is programmed to create an artificial haptic feedback pulse to the brake pedal by opening a normally-open isolation valve between the master cylinder and the brake circuit to move a master cylinder piston until a compensation port opens.
