  • Patent number: 10562510
    Abstract: A method for operating a vehicle brake system, including: classifying a fault signal, indicating a fault of an electronic actuating device of the brake system, the actuating device outputting a brake pressure for a brake of the vehicle in a normal operating mode and a pneumatic actuating device for outputting the brake pressure in a backup operating mode, as a fault signal of a first fault category if the fault is a fault in which a switchover from the electronic actuating device afflicted with the fault to the pneumatic actuating device leads to an improvement in the outputting of the brake pressure; and switching from the electronic actuating device to the pneumatic actuating device, to output the brake pressure using the pneumatic actuating device, if the fault signal is a fault signal of the first fault category. A related computer readable medium, apparatus and brake system are also described.

  • Patent number: 7540189
    Abstract: A method for detection of a variable parameter of a vehicle with the aid of a measurement device, by which measured values are evaluated as sensor signals of at least one sensor element which is arranged in the immediate vicinity of an actuating element with an electrical drive, in which no evaluation of the measured values is carried out or performed during an influencing time period between a time of a change in the electrical drive for the actuating element and a time in which this change is essentially still just exerting an influence on the measured values.

  • Patent number: 7478888
    Abstract: An electronic vehicle service braking system having at least one braking cylinder and a pressure control module with a control chamber and a working chamber. The working chamber is connected to an air supply via a supply line, the control chamber is connected to the air supply via a connecting line and an inlet valve and to the atmosphere via an outlet valve. The control chamber is also connected to a back-up braking system via a back-up line and a back-up valve, and a control system is provided for controlling at least the inlet valve and the back-up valve. The control system controls the valves such that the back-up valve is opened together with the inlet valve, enabling air to flow into the control chamber when an ABS signal for a rise in pressure follows a drop in pressure.

  • Patent number: 7284802
    Abstract: The invention relates to a motor vehicle comprising a compressed-air braking system. Said vehicle has two braking cylinders, which can be impinged by compressed-air from a compressed-air reserve by means of a manually actuated brake valve. The braking cylinders have ABS pressure-control valves, which can be selectively impinged by compressed air from the compressed-air reserve, using a slip control valve. A stability sensor detects a motor vehicle position and a control device selectively supplies the slip control valve and the ABS pressure-control valves with compressed air, in accordance with the signals of the stability sensor.

  • Patent number: 6510527
    Abstract: A method and a system for data protection of fixed and learned control data of duplicated, program-controlled computers, in which the control parameters are stored in an EEPROM. The memory available in the EEPROM is divided into three areas. Each area is monitored using a check sum (check sum 1, check sum 2, check sum 3) that is stored therein. Only the self-learned variables are maintained redundantly. Thus, the ability to store more data than previously in the EEPROM with the same data protection and the same accessibility is provided, thus allowing more flexible solutions with respect to varying customer requirements to be offered.
