Abstract:
1. A vehicle driven by an internal combustion engine and an electric motor that are connected to shafts configured to transfer power through a clutch configured to connect the power or disconnect the connection of the power, the vehicle comprising an apparatus including: an inclination sensor which finds an inclination of a road surface on which the vehicle runs and an electronic control device which controls operation of the electric motor and the clutch, in which: the electronic control device comprises: a determination unit for determining, while the clutch is disengaged, whether a condition, where an absolute value of a rotational speed of the electric motor is equal to or less than a predetermined first threshold and where torque of the electric motor is equal to or more than a predetermined second threshold, lasts for a predetermined third threshold or more; a torque control unit for controlling the electric motor to limit the torque of the electric motor; and a clutch control unit for controlling the clutch to be engaged when it is determined, while the clutch is disengaged, that the condition where the absolute value of the rotational speed of the electric motor is equal to or less than the first threshold and the torque of the electric motor is equal to or more than the second threshold lasts for the third threshold or more, wherein the torque control unit controls the electric motor to cancel the limitation of the torque of the electric motor after a predetermined period elapses after the torque of the electric motor is limited, wherein the predetermined period is extended when the inclination of the road surface exceeds an angle of upgrade threshold.
