Abstract

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.

Description

technical field [0001] The invention relates to a method for providing a driver of a motor vehicle with tactile information about the operating state of a brake system and to a brake system. Background technique [0002] Hydraulic vehicle braking systems are known, which are constructed as power-assisted braking systems and which, in addition to the brake master cylinder, which can be operated by muscular force, also comprise a further electrically controllable pressure and volume supply device, the wheel brakes are hydraulically connected to the brake master cylinder and the brake master cylinder provides the pressure and volume for operating the wheel brakes, the pressure and volume supply device is controlled in the "brake-by-wire" operating mode wheel brakes. In the event of failure of the electrically controllable pressure and volume supply means, the actuation of the wheel brakes is carried out exclusively by the muscular force of the driver of the vehicle. [0003] ...
