Abstract:
1. An engine operation start control device of a hybrid vehicle comprising a power output device having an internal combustion engine and an electric motor, the control device being able to perform an intermittent control for intermittently operating the engine and perform a cranking of the engine until an engine speed reaches a target engine speed when the control device starts the operation of the engine during the intermittent control being performed, wherein in case that the device starts the operation of the engine when a speed of the hybrid vehicle is higher than or equal to a predetermined speed and a power required for the power output device is larger than or equal to a predetermined power during the intermittent control being performed, the control device sets the engine speed, which increases as the speed of the hybrid vehicle increases, as the target engine speed, and wherein when the predetermined speed is referred to as first speed and the predetermined power is referred to as first power, in case that the control device starts the operation of the engine when the speed of the hybrid vehicle is higher than or equal to a predetermined second speed and the power required for the power output device is larger than or equal to a predetermined second power during the intermittent control being performed, the control device controls a torque input to an output shaft of the engine for cranking the engine, depending on the required power.
