Abstract:
A vehicle includes an engine, a first MG (motor generator), a second MG, a planetary gear mechanism provided among the engine, the first MG and the second MG, a battery, and an ECU. The ECU executes batteryless travel control when the battery is abnormal. The batteryless travel control includes engine F/B control for controlling a rotation speed of the engine to become a target rotation speed, and power balance control for controlling a requested driving force to be output and allowing a power generated by the first MG to become equal to a power discharged by the second MG. When the rotation speed of the engine is higher than a threshold speed higher by a prescribed value than the target rotation speed while the batteryless travel control is in execution, the ECU decreases the requested driving force.
