Abstract

A motor vehicle including a unit (2) consisting of an internal combustion engine, a generator supplying current to electric motors (12, 16) coupled with driving wheels (14, 18) over an energy distributor/power electronics system (8) and a battery which is supplied with energy by the internal combustion engine/generator unit via the energy distributor (2). An electronic control system (20) controls the energy distributor (8) as a function of a driving signal according to boundary conditions, for example, according to the least possible specific fuel consumption. A temporary increase in the power required to drive the motors can be supplied by the battery (22). In the event that the increase in power lasts for longer periods, the internal combustion engine, which as far as possible operates in a state that ensures low fuel consumption, is accelerated in order to cover the demand for high power. At the maximum output of the internal combustion engine, the energy stored in the battery (22) supplies the power for the additional thrust.
