A control system of a vehicle (Ve), the vehicle (Ve) including a drive power source, drive wheels, a first clutch of an oil bath type comprising a wet clutch filled with oil for cooling, the first clutch being configured to selectively transmit and cut off power on a power transmission path through which torque is transmitted between the drive power source and the drive wheels, and a second clutch of a shaft-center oil feed type in which oil is suppled from a shaft center to friction plates, the second clutch being configured to selectively transmit and cut off power on the power transmission path, the control system comprising: an electronic control unit, the electronic control unit being configured to place the first clutch in a half-engaged state with a predetermined clutch torque capacity, when the vehicle (Ve) is started, perform start control in a first mode using the second clutch, by gradually increasing a clutch torque capacity of the second clutch from a released state, and characterised in that the electronic control unit is further configured to switch the start control from the first mode using the second clutch to a second mode using the first clutch, when the increased clutch torque capacity of the second clutch reaches the clutch torque capacity of the first clutch, and transmit output torque of the drive power source to the drive wheels, to generate drive power for starting, based on operation of the first clutch and operation of the second clutch. a drive power source, drive wheels, a first clutch of an oil bath type comprising a wet clutch filled with oil for cooling, the first clutch being configured to selectively transmit and cut off power on a power transmission path through which torque is transmitted between the drive power source and the drive wheels, and a second clutch of a shaft-center oil feed type in which oil is suppled from a shaft center to friction plates, the second clutch being configured to selectively transmit and cut off power on the power transmission path, the control system comprising: an electronic control unit, the electronic control unit being configured to place the first clutch in a half-engaged state with a predetermined clutch torque capacity, when the vehicle (Ve) is started, perform start control in a first mode using the second clutch, by gradually increasing a clutch torque capacity of the second clutch from a released state, and characterised in that the electronic control unit is further configured to switch the start control from the first mode using the second clutch to a second mode using the first clutch, when the increased clutch torque capacity of the second clutch reaches the clutch torque capacity of the first clutch, and transmit output torque of the drive power source to the drive wheels, to generate drive power for starting, based on operation of the first clutch and operation of the second clutch. place the first clutch in a half-engaged state with a predetermined clutch torque capacity, when the vehicle (Ve) is started, perform start control in a first mode using the second clutch, by gradually increasing a clutch torque capacity of the second clutch from a released state, and characterised in that the electronic control unit is further configured to switch the start control from the first mode using the second clutch to a second mode using the first clutch, when the increased clutch torque capacity of the second clutch reaches the clutch torque capacity of the first clutch, and transmit output torque of the drive power source to the drive wheels, to generate drive power for starting, based on operation of the first clutch and operation of the second clutch.
