Abstract:
1. A controller for a drive system having an engine, a first rotating electric machine generating electric power by driving force from said engine, a second rotating electric machine generating electric power under regenerative braking of a vehicle, and a power storage mechanism, the drive system allowing the vehicle to run by driving force of at least one of said first rotating electric machine and said second rotating electric machine both provided with electric power from said power storage mechanism, the controller for the drive system comprising: a first calculation portion calculating a value of electric power to be stored in said power storage mechanism; a second calculation portion calculating a value of electric power to be generated by said second rotating electric machine; and a control portion controlling said drive system such that, when the value of electric power to be stored in said power storage mechanism is larger than the value of electric power to be generated by said second rotating electric machine under regenerative braking of said vehicle, said engine is driven to allow said first rotating electric machine to generate electric power to be stored in said power storage mechanism.
