Abstract: A method for detecting misuse of a safety belt in a vehicle by a control unit (12) of the vehicle, comprising the following steps: a) recording vehicle parameters (P), b) supplying the vehicle parameters (P) to an artificial neural network (40); c) recording the at least one output value (A) of the artificial neural network (40), and d) detection of whether or not there is a misuse of the safety belt based on the output value (A). There is also a safety belt system (10) for a vehicle.

Abstract: A brake system for motor vehicles, which can be actuated in a “brake-by-wire” operating mode both by the vehicle driver and independently of the vehicle driver. In the “brake-by-wire” operating mode the system can be operated in at least one fallback operating mode, with a brake master cylinder, actuated by a brake pedal, having a housing and two pistons, which delimit two pressure chambers, are assigned to brake circuits with wheel brakes, a pressure medium reservoir, one electrically actuable inlet valve per wheel brake for setting wheel-individual brake pressures, a first electrically controllable pressure provision device for loading the wheel brakes with pressure, and a second electrically controllable pressure provision device with at least one vacuum connector and a pressure connector, the vacuum connector is connected to the pressure medium reservoir. The pressure connector is connected to at least one wheel brake without a valve being connected in between.

Abstract: A method of transmitting data between a first and a second device (2, 3) by way of a power supply line between the first and the second device (2, 3). The power supply and the data transmission take place alternately in a power supply time window (21) and in a data transmission time window (22). As a result of this measure, a separate data transmission line is not be necessary.
