STEUERVORRICHTUNG UND STEUERVERFAHREN FÜR DIE ANTRIEBSVORRICHTUNG EINES HYBRIDFAHRZEUGS

摘要

A control method for a drive apparatus of a hybrid vehicle in which an assist power source is connected to an output member connected to an engine through a torque transmitting member whose torque capacity is changed according to an engagement control amount includes the steps of maintaining a rotational speed of the assist power source at a predetermined rotational speed (step (S02); continuously changing the engagement control amount while maintaining the rotational speed of the assist power source at the predetermined rotational speed (step S04); and leaning a relationship between output torque of the assist power source for maintaining the rotational speed of the assist power source and the engagement control amount when the output torque of the assist power source reaches a predetermined value while the engagement control amount is changed (step S06).
