An ECU that controls a plug-in hybrid vehicle starts an engine when a required power as a value obtained by subtracting a required discharge amount from a drive power is larger than a threshold during intermittent control in a CD mode, and stops the engine when the required power is smaller than a threshold. When intermittent control is being performed in the CD mode, the ECU limits the required discharge amount Pout to a relatively small value in a range where an engine coolant temperature is low, and sets the required discharge amount relatively large instead of imposing a limit thereon in a range where the engine coolant temperature is high.

A fluid pressure brake unit generates a friction braking force by supplying an operating fluid to a wheel cylinder provided to each wheel of a vehicle so as to press a brake pad against the wheel. A regenerative brake unit generates a regenerative braking force by electric power regeneration to a motor that drives the wheel. A battery collects electric power from the motor. A low-temperature determination unit determines that the temperature of the battery is low when the temperature of the battery is below a predetermined temperature range. A battery temperature increasing unit generates, when the temperature of the battery is determined to be low, a braking force to the vehicle by at least either a fluid pressure brake unit or a regenerative brake unit during acceleration of the vehicle by the motor or the engine.

A motor is wholly arranged on an input shaft such that the rotation speeds of the motor and the input shaft are synchronous. The motor has the functions of an electric generator and can drive a vehicle to run by a reactive force generated by the magnetic field of the electric generator such that the vehicle generates power during running and therefore avoids consuming the power of the engine due to the load of the electric generator, and thus, the aim of power conservation is achieved. In the hybrid drive mode, the vehicle does not need a clutch and a brake to shift the gear at the moment of startup and during running and therefore realizes stepless transmission and can transmit a large torque.

A controller for a vehicle includes a target traveling torque calculating unit, a target torque calculating unit, and a torque controlling unit. The target torque calculating unit is configured to execute an increasing process that increases, on condition that the target traveling torque is greater a threshold, a ratio of the target engine torque to the target traveling torque as compared to a case in which the target traveling torque is less than or equal to the threshold. The threshold is less than a maximum output value, which is a maximum value of a torque that can be generated by the motor-generator.
