PROBLEM TO BE SOLVED: To efficiently perform regeneration control of MG (motor generator) in a system including an engine and the MG as a vehicle power source.SOLUTION: Regeneration control is performed: specifically, during vehicle deceleration, a first MG 13 or a second MG 14 is driven by power of an axle 28, and electric power generated at the MG is charged to a battery 31. In this case, required brake torque is calculated on the basis of a vehicle speed and a brake operation amount, a target energy regeneration amount is calculated on the basis of the required brake torque and the charged state of the battery 31, and connection/disconnection of clutches 23 to 25 is switched to change the mode of the regeneration control according to at least one of the target energy regeneration amount, the required brake torque, and the vehicle speed. Further, torque distributions of the MGs 13 and 14 are calculated on the basis of the target energy regeneration amount and the vehicle speed. According to the torque distributions, field current of the MGs 13 and 14 is controlled to control regeneration torque of the MGs 13 and 14. |
