Abstract:
1. A regenerative control apparatus for a vehicle equipped with an engine and an automatic transmission mechanism equipped with a lock-up clutch, the automatic transmission mechanism transmitting an output of the engine to wheels of the vehicle, the regenerative control apparatus comprising: a first detection unit detecting information indicative of an engagement state of the lock-up clutch; a second detection unit detecting information indicative of revolutions per unit time of the engine; a rotary electric machine performing regenerative generation using energy brought about by the engine when the vehicle is in deceleration state; a first control unit, using the information provided by both the first detection unit and the second detection unit, controlling the rotary electric machine so as to cause the rotary electric machine to perform the regenerative generation at a generation level lower than a regenerative generation level given when the lock-up clutch is in a complete engagement state in the deceleration state of the vehicle, in cases where the lock-up clutch is in either a complete disengagement state or a slipping state in the deceleration state of the vehicle; and a second control unit, using the information provided by both the first detection unit and the second detection unit, controlling the lock-up clutch so as to shift the engagement state of the lock-up clutch to either the slipping state or the complete disengagement state, provided that the number of revolutions per unit time becomes equal to or less than a threshold in a condition where the lock-up clutch is in the complete engagement state during the regenerative generation.
