摘要： The invention relates to a method for providing haptic information to the driver of a motor vehicle, equipped with a brake-by-wire brake system, about the operating state of the brake system, in which method the brake pedal characteristic is generated by a pedal travel simulator, in the form of a functional relationship between the brake pedal opposing force and the brake pedal travel, and is modified as a function of an operating state. In order to provide the driver with the haptic information channel via which electronically controlled information can be communicated to the driver during braking, without the impression of a defect arising, the invention proposes that a basic brake pedal characteristic is generated by a passive simulator spring which assigns pedal travel, on which pedal return travel transporting the haptic information is superimposed, to a given pedal force in an unchanging, constant relationship.

摘要： A method for operating a brake system of a motor vehicle, comprises a hydraulic operational brake device that has hydraulically-actuatable wheel brakes on at least one front axle of the motor vehicle, a parking brake device having wheel brakes on a rear axle of the motor vehicle, each of which can be actuated by means of an electromechanical actuator, and wheel speed sensors on the wheels of said front and rear axles. During braking by means of said hydraulic operational brake device while the vehicle is travelling, braking is carried out by said parking brake device.

摘要： A method for operating a motor vehicle brake installation. An electrically controllable pressure modulation device having a pump-valve arrangement is hydraulically arranged between the primary brake system and the front axle brakes. The pump-valve arrangement includes, for each front brake, a first valve, arranged between the inlet valve of the primary brake system and the brake, and an electrically activatable pump, with a suction and pressures ports. The pressure port is connected to the brake. In the presence of a predetermined condition of the primary brake system and of an actuation of the master brake cylinder by the driver, a build-up of brake pressure at the front axle brakes is performed by the pump-valve arrangement. The pressure set by the pump-valve arrangement is higher than the brake pressure in the master brake cylinder, whereas the brake pressure of the master brake cylinder prevails at the brakes of the rear axle.

摘要： An electrohydraulic brake system method for motor vehicles having a wheel-specific brake control function (ABS, ESC, TCS) and hydraulically actuable wheel brakes (43, 44, 45, 46), communicating with an electrically controllable pressure supply device. The pressure supply device (40) having a cylinder-based piston arrangement with a pressure space driven by an electromechanical actuator (2, 4). To set a brake system pressure (Psys) wherein a wheel-specific wheel setpoint pressure (Pi) is predefined for each wheel brake, and a pressure regulating process (301) is carried out, wherein at certain times a control process (303) of the pressure medium volume which is output by the pressure supply device is carried out instead of the pressure regulating process (301) of the brake system pressure, switching over (302) from the pressure regulating process to the control of the pressure medium volume is carried out as a function of the wheel setpoint pressures (Pi).

摘要： A method and a brake system for providing haptic information for a driver of a motor vehicle equipped with a brake-by-wire brake system concerning an operational state of the brake system. The brake system has a main brake cylinder which can be actuated by a brake pedal, having at least one pressure chamber associated with at least one wheel brake, and a simulation device which co-operates with the main brake cylinder and gives the driver a brake pedal sensation in a brake-by-wire operating mode. When a predetermined operational state occurs in the brake-by-wire operating mode, a brake pedal reaction, as a change to the stiffness of the brake pedal sensed by the driver is carried out by means of a disengaging valve which is connected to the pressure chamber of the main brake cylinder and by which the action of the simulation device can be switched on and off.
