STEUERUNGSVORRICHTUNG FÜR EINEN HYBRIDGETRIEBENEN KRAFTWAGEN

摘要

A control device of a hybrid drive vehicle comprising an internal combustion engine and a power generating motor as a driving source for vehicle, wherein, immediately after it is detected that an air/fuel ratio of air/fuel mixture supplied to the engine is changed to lean side (S44 to S46), the power generating motor (2) is operated as a motor (S47, S48) in order to assist an output from the engine and, immediately after it is detected that an air/fuel ratio of air/fuel mixture supplied to the engine is changed to rich side (S44, S52, S53), the power generating motor (2) is operated as a generator (S54, S55) in order to apply regenerative braking to the engine, whereby a difference in output torque from the engine produced when the air/fuel ratio of the supplied air/fuel mixture is varied can be compensated for sufficiently without delay.
