Electronic device, vehicle system and method for safeguarding wireless data communication

A brake system includes a brake pedal for actuating a master cylinder having two pistons and corresponding pressure chambers, where the system can be operated in a brake-by-wire mode and also a fallback mode. The system also includes a first electrically controllable pressure source and a second electrically controllable pressure source. The first and second electrically controllable pressure sources each have corresponding output flows that are connected together. The second electrically controllable pressure source can therefore provide output volume flow in the event the first electrically controllable pressure source fails.

Brake system for motor vehicles and method for operating the brake system

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.

A brake system for motor vehicles, which brake system can be actuated both by the vehicle driver and also independently of the vehicle driver in a 'brake by wire' operating mode, is preferentially operated in the 'brake by wire' operating mode, and can be operated in at least one fall-back operating mode in which only operation by the vehicle driver is possible. The brake system has inter alia an electrohydraulic pressure generating device () which outputs a brake system pressure, and a pressure modulation unit which has one inlet valve (-) and one outlet valve (-) per wheel brake () for setting wheel-specific brake pressures derived from the brake system pressure, wherein the inlet and outlet valves (--) output or transmit the brake system pressure when in the non-actuated state.
