(54) CONTROL UNIT FOR TRANSMISSION


(57) A control device (1) for a transmission (10) that includes a lock-up clutch (25) that is interposed between an engine (50) and the transmission (10), and an input clutch (C1) capable of connecting and disconnecting a torque transmission between the engine (50) and drive wheels (WL and WR). An amount of vehicle deceleration change, which can be sensed by a driver, is obtained based on vehicle deceleration at a time when the input clutch (C1) is not released and a previously set reference value. A target amount of the vehicle deceleration change, which cannot be sensed by the driver, is set based on the amount of the vehicle deceleration change. An engaging force of the lock-up mechanism (25) and/or the input clutch (C1) is controlled to reduce the vehicle deceleration such that the target amount of the vehicle deceleration change is obtained.
