Claims (7)

An engine and a motor as a drive source for transmitting power to the drive wheels, and an automatic transmission for shifting the rotation of the engine and transmitting the rotation to the drive wheels, the automatic transmission transmitting power between the engine and the engine. A hybrid vehicle having a clutch for disconnecting or connecting a path,
Based on whether the traveling mode of the hybrid vehicle is a first traveling mode in which shift control is automatically performed without operation by an occupant or a second traveling mode in which shift control is performed according to operation by an occupant, A hybrid vehicle comprising a control unit that controls an assist torque output from the motor during a non-complete engagement period of a clutch. The hybrid vehicle according to claim 1, wherein the first traveling mode is an automatic traveling mode in which gear shift control and drive control are automatically performed to perform acceleration/deceleration traveling automatically regardless of an operation of the occupant. When the traveling mode is the first traveling mode, the control unit controls the assist torque to be smaller than when the traveling mode is the second traveling mode. The hybrid vehicle according to claim 1 or 2. Further comprising a vehicle speed detector for detecting the vehicle speed of the hybrid vehicle,
When the assist torque when the traveling mode is the first traveling mode is defined as a first assist torque and the assist torque when the traveling mode is the second traveling mode is defined as a second assist torque. ,
The hybrid vehicle according to claim 3, wherein the control unit performs control so that the ratio of the first assist torque to the second assist torque becomes smaller as the vehicle speed detected by the vehicle speed detecting unit becomes higher. When the traveling mode is the first traveling mode, the control unit controls the assist torque to be larger than when the traveling mode is the second traveling mode. The hybrid vehicle according to claim 1 or 2. Further comprising a vehicle speed detector for detecting the vehicle speed of the hybrid vehicle,
When the assist torque when the traveling mode is the first traveling mode is defined as a first assist torque and the assist torque when the traveling mode is the second traveling mode is defined as a second assist torque. ,
The hybrid vehicle according to claim 5 , wherein the control unit performs control so that the ratio of the second assist torque to the first assist torque decreases as the vehicle speed detected by the vehicle speed detecting unit increases. Further comprising a battery for supplying power to the motor,
When the remaining capacity of the battery is less than a predetermined value, the control unit outputs different assist torque from the motor during the incomplete engagement period of the clutch between the first traveling mode and the second traveling mode. The hybrid vehicle according to any one of claims 1 to 6, which is controlled as follows.
