Vehicle, control method, and computer program

摘要

The disclosed vehicle, control method, and program lead to improved fuel consumption, durability, and stability. When the vehicle starts to move, a clutch control performs controls so as to set the clutch to a half clutch state, in which a part of the motive force is transmitted, and thereafter to a connected state, in which the entire motive power is transmitted. When the clutch is the half clutch state, an electric motor control unit controls an electric motor to generate an assist torque when the vehicle starts to move equal to the difference between the torque requested by the driver and the idling torque generated when the engine is idling. The disclosed invention can be applied to hybrid vehicles.

主权项

1. A vehicle that is driven by an internal combustion engine and an electric motor, a shaft of the internal combustion engine and a shaft of the electric motor for transmitting power being connected by a clutch that transmits power or cuts the transmission of power, the vehicle comprising a device including:
a clutch control unit that controls the clutch to be in a partial engagement state for transmitting some power, and then, to be in an engagement state for transmitting the whole power, when the vehicle starts; an electric motor control unit that controls the electric motor to generate torque assisting the start of the vehicle, when the clutch is in the partial engagement state; a determination unit that determines whether the vehicle starts from an uphill having an inclination equal to or larger than a predetermined inclination; and a correction unit that corrects the assist start torque larger than that on a flat road and corrects an upper limit value of the torque, generated by the electric motor, to be small, when the vehicle is determined to start from the uphill having the inclination equal to or larger than the predetermined inclination.
