Abstract
A vehicle drive device includes an engine (), a motor generator (MG) driven by the engine () and generating power, a motor generator (MG) driving the vehicle and generating electric power at the time of regenerative braking, a battery (B) capable of exchanging power to/from the motor generators (MG, MG), a temperature sensor () detecting temperature of the battery (B), and a controller () controlling the motor generators (MG, MG). If reduction in a required driving torque value of the motor generator (MG) is detected, the controller changes start timing of regenerative braking by the motor generator (MG) dependent on an output of the temperature sensor ().
