Abstract
A vehicle includes an engine, a motor, a rotary electric machine, a battery, and an ECU. The ECU is configured to control the rotary electric machine to generate electric power when the engine is started during the motor traveling mode and provide a cranking torque to the engine, the electric power generated by the rotary electric machine increasing as a vehicle speed increases, and determine whether or not to start the engine based on a comparison between a sum of electric power and a value corresponding to electric power acceptable by the battery. The sum of electric power is a sum of first electric power actually input into and output from the battery during the motor traveling mode and second electric power predicted to be generated by the rotary electric machine while the cranking torque is provided to the engine.
