Abstract
In a vehicle that includes an engine, a motor, a generator, a battery electrically connected to the motor and the generator, and a transmission provided between the motor and an output shaft coupled to a drive wheel, an ECU executes 'battery-less travel control' in which, at the time of a failure of the battery, the battery is isolated from the motor and the generator, the generator is caused to generate electric power by generating a torque, corresponding to an accelerator pedal operation amount, from the generator, and the vehicle is caused to travel by driving the motor using the electric power generated by the generator. The ECU suppresses losing a balance of input and output electric powers between the generator and the motor by filtering the accelerator pedal operation amount when a vehicle speed exceeds a limit vehicle speed during the battery-less travel control.
