Abstract: The disclosure is concerned with control system and control method, for a vehicle including a driving power source, drive wheels, a first clutch, and a second clutch. An electronic control unit, which is included in the control system, places the first clutch in a half-engaged state with a predetermined clutch torque capacity, when the vehicle is started, performs 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 switches 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.

Abstract: A control device includes a deceleration flex-torque calculation unit that calculates a target torque capacity of a lock-up clutch when a state of the lock-up clutch is controlled to a deceleration flex control state, an acceleration flex-torque calculation unit that calculates a target torque capacity of the lock-up clutch when the state of the lock-up clutch is controlled to an acceleration flex control state, and a control unit that controls a torque capacity of the lock-up clutch to a target torque capacity calculated by the acceleration flex-torque calculation unit, during a period until a target torque capacity calculated by the acceleration flex-torque calculation unit falls below a target torque capacity calculated by the deceleration flex-torque calculation unit, when the state of the lock-up clutch is shifted from the acceleration flex control state to the deceleration flex control state.
