  • Publication number: 20090115247
    Abstract: The invention relates to a brake system which comprises an actuating device (26), especially a brake pedal (30), and a control/regulation device (22). Said control/regulation device (22) controls at least one electromotive drive device (7a, 7b, 8) in response to the movement and/or position of the actuating device (26). The drive device adjusts a piston (1, 1a, 1b) of a piston/cylinder system via a non-hydraulic transmission device, thereby adjusting a pressure in the working compartment (4?, 4?a, 4b?) of the cylinder. Said working compartment is connected to a wheel brake (15, 17) via a pressure conduit (13, 13a). A valve (14, 14a, 15, 15a, 14?, 14a?) is interposed between the brake cylinder of the wheel brake and the working compartment of the piston/cylinder system. The control/regulation device opens the valve for pressure suppression or pressure build-up in the brake cylinder and closes it in order to maintain the pressure in the brake cylinder.

  • Patent number: 6624738
    Abstract: The invention relates to an electronic control unit for a motor vehicle with a plurality of data networks and an electronic immobilizer. The control unit according to the invention is configured both as a vehicle-end control section for the electronic immobilizer and as a gateway between at least two of the data networks. At least one component of the gateway also serves as a component of the vehicle-end control section for the electronic immobilizer. Preferably, there is common use of components of the gateway for the immobilizer function such that, in addition to the normal vehicle-end immobilizer control section, a further, redundant vehicle-end immobilizer control section, is formed, which significantly reduces the failure rate of the immobilizer.

  • Patent number: 6512453
    Abstract: A device for ABS-integrated brake pad wear indication in a motor vehicle in which all line paths are constructed to avoid current loops and induction surfaces. All the wheel speed and pad wear signal lines respectively lead to the ABS or ABS/ASR control unit in a single strand or are combined at least via common fixings, grommets, intermediate connecting plugs and a single terminal connecting plug. Owing to coding of different warning signals for, e.g., ABS, ASR and brake pad wear, the signal connection between the ABS or ABS/ASR control unit and the instrument cluster in the dashboard is reduced to a single line.

  • Patent number: 5491383
    Abstract: A motor vehicle light controlling device includes an operating switch and electronics assigned to the operating switch for supplying current to a multiplicity of lamps of the operating light system. At least one controlled switching component provides a clock-controlled supply of current to the assigned lamp circuit. The device is divided into a light switch module and a rear lamp module. A clock control provided, distributed over both modules, in order to influence the lamp currents of the vehicle operating lights. That is, in order to lower the luminosity of certain lights when required, and to be able to increase the on-board system voltage temporarily without the luminosity or lamp power changing as a result. The latter is of interest, for example, for the brief driving of electrical heating elements or servomotors to achieve an advantageously high utilization of conductor material.
