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.

Safety switch for preventing an unintentional vehicle battery discharge

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.
