发明名称 CONTROL DEVICE AND CONTROL METHOD OF TRANSMISSION
摘要 PROBLEM TO BE SOLVED: To more appropriately set a line pressure during a neutral control and to improve fuel economy of a prime mover while the neutral control can be quickly released.SOLUTION: A transmission ECU executes a release control and a low pressure standby control as a neutral control to decrease an oil pressure Psl1 supplied to a clutch C1 which is a start clutch in a plurality of clutches and brakes in an automatic transmission, from a hydraulic control device in accordance with satisfaction of preliminarily determined conditions for starting the neutral control. When an oil temperature Toil detected by an oil temperature sensor 99 is lower than a high-temperature side determination temperature Tref1, the transmission ECU decreases a line pressure PL during the neutral control compared to a line pressure when the oil temperature Toil is equal to or higher than the high-temperature side determination temperature Tref1 (steps S230 to S290).
