  • OPERATING METHOD FOR AN INTERNAL COMBUSTION ENGINE AND ASSOCIATED MOTOR VEHICLE
    Publication number: 20100191448
    Abstract: A method for operating an internal combustion engine in a motor vehicle, in which the internal combustion engine is switched off automatically as soon as it is not required, and in which the internal combustion engine is started automatically as soon as it is required or as soon as a timeout has expired. In order to increase the service life of the battery, the timeout is changed in dependence on a characteristic value which is correlated with the capacity of the battery.

  • Safety switch for preventing an unintentional vehicle battery discharge
    Patent number: 7129598
    Abstract: A vehicle electric supply system includes a semiconductor safety switch that interruptibly couples the vehicle battery to electric consuming devices that are supplied by an electric socket on board the vehicle. A programmable control unit controls opening and closing of the switch, as a function of a monitored vehicle parameter, such as elapsed time, battery charge state or current consumption via the vehicle socket.

  • Starting process for an internal-combustion engine
    Patent number: 6286470
    Abstract: A process and apparatus for starting an internal-combustion engine of a vehicle is provided, having a starting device for starting the internal-combustion engine in which the rotational starting speed can be controlled or automatically controlled. For minimizing starting energy, shortening the starting time, increasing the starting safety and reducing the emissions during the start, the rotational speed generated by the starting device is adjusted to a defined maximal rotational starting speed.
