Abstract
A system for monitoring a starter unit in a motor vehicle is provided. The vehicle is equipped with an electrical machine serving as both a starter and a generator, an inverter for converting the current generated or required in the electrical machine, and a control unit for controlling the operation of the unit consisting of the electrical machine and the inverter as a function of input signals. The control unit is capable of being activated at intervals even when the vehicle is not operating. An additional control function is provided to activate or deactivate the inverter as a function of vehicle operating information. As a result, unintentional movement of the vehicle is prevented during automatically occurring activation periods of the control system.
