The present invention comprises an engine (1) and an assist motor (10) as power sources. An engine control module (9) comprises a torque assist control unit (9a) that controls the assist motor via a plurality of types of switching patterns having different torque assist levels. A CVT control unit (8) comprises a torque assist coordination control unit (8a) that, when a torque assist request is inputted from the torque assist control unit (9a), performs control that increases commanded hydraulic pressure so as to increase the hydraulic pressure of a hydraulically operated member. When performing control that increases the commanded hydraulic pressure, the torque assist coordination control unit (8a) sets a uniform commanded hydraulic pressure level regardless of the type of switching pattern.
驱动源具有发动机(1)和辅助电机(10)。发动机控制模块(9)具有扭矩辅助控制部(9a),其通过扭矩辅助量不同的多种切换模式进行辅助电机的控制。CVT控制单元(8)具有扭矩辅助协调控制部(8a),其在从扭矩辅助控制部(9a)输入了扭矩辅助请求时,进行提高指示油压的控制以提高油压工作部件的油压。扭矩辅助协调控制部(8a)在进行提高指示油压的控制时,与切换模式的种类无关地对指示油压的高度进行统一。
