Abstract:
1. A hybrid vehicle comprising an engine, an electric motor, a clutch disposed in a power transmitting path between the engine and the electric motor, a transmission of a step-variable type disposed in a power transmitting path between the electric motor and drive wheels, an electronic control device communicatively coupled to the transmission and comprising a processor and a non-transitory memory storing a computer readable and executable instruction set which, when executed by the processor: determines if a start of the engine is required concurrently with a shift-down action of the transmission when the hybrid vehicle is in an electric vehicle drive mode; calculates an output-related value of the engine when the start of the engine is required concurrently with a shift-down action of the transmission when the hybrid vehicle is in the electric vehicle drive mode, the output-related value relating to at least one of a torque of the engine upon starting and a speed of the engine upon starting; determines a shift position of the transmission to be established after the shift-down action is completed on the basis of the output-related value when the start of the engine is required concurrently with the shift-down action of the transmission and the hybrid vehicle is in the electric vehicle drive mode; and provides control signals to the transmission to shift the transmission to the determined shift position.
