PCT No. PCT/DE92/00834 Sec. 371 Date Jun. 22, 1994 Sec. 102(e) Date Jun. 22, 1994 PCT Filed Sep. 30, 1992 PCT Pub. No. WO93/07020 PCT Pub. Date Apr. 15, 1993.A passenger automobile or truck contains a unit which is formed by an internal combustion engine and a generator and which powers electric motors coupled with driving wheels of the vehicle via an energy distributor in the form of power electronics. An accumulator which can likewise be coupled with the electric motors via the energy distributor is provided as an additional power source. An electronic control unit receives driving signals from an accelerator pedal, in particular a position signal and a speed signal. The position signal of the throttle is interpreted as a request for a determined permanent output to be supplied by the internal combustion engine. The internal combustion engine is revved up to a new operating point in an "optimal" manner (e.g. with favorable fuel consumption), for example when a higher output is requested, while the generator is entirely or partially uncoupled from the load. Energy for accelerating the vehicle is provided in the meantime by the accumulator. The speed signal determines the amount of acceleration. By means of a selector switch, an operation powered exclusively by stored energy may be switched on when the internal combustion engine is turned off if no special sensors are provided for this purpose. |
