The invention relates to a hybrid vehicle and a control method of the hybrid vehicle. The hybrid vehicle is provided with: an engine; a motor; the driving system battery is connected to the driving system power line; an auxiliary system battery connected to the auxiliary system power line; a bidirectional power converter configured to step down power of the driving system power line and supply the power to the auxiliary system power line, step up power of the auxiliary system power line and supply the power to the driving system power line; and a control device. The control device is configured to control the engine, the motor, and the bidirectional power converterduring starting the engine by the motor while starting the engine by the motor in a manner that the power of the auxiliary engine system power line is boosted by the bidirectional power converter and supplied to the drive system power line, while the engine is cranked by the motor.
