Abstract
An electric drive arrangement for internal combustion engines in motor vehicles having an electric starter coupled to the internal combustion engine, and an electric generator drive connected with the internal combustion engine. The arrangement is connected to a supply battery via a semiconductor circuit arrangement, which determines the operation of the generator either in a generator mode or a motor mode. An electronic control device is used for controlling the starting operation of the internal combustion engine as a function of the signal of at least one temperature sensor with the aid of the generator operated as a motor, either alone or together with the starter. This arrangement makes it possible to achieve quicker and more comfortable starting operations in combination with lower pollutant emissions. The starting operations can be carried out reliably even at very low temperatures.
