发明名称 AUTOMATIC TRANSMISSION AND METHOD FOR CONTROL AT TAKEOFF OF SAME
摘要 A transmission controller increases an indicated hydraulic pressure to a starting frictional engagement element to a normal hydraulic pressure, causes a hydraulic piston to stroke and executes a learning control of the indicated hydraulic pressure so that a time until the starting frictional engagement element starts generating a transmission capacity after the range is switched from the neutral range to the drive range becomes a target time when a range is switched from a neutral range to a drive range. The transmission controller further detects a driver's starting intention and increases the indicated hydraulic pressure to the starting frictional engagement element to a starting time hydraulic pressure higher than the normal hydraulic pressure and prohibits the learning control if the starting intention is detected before the starting frictional engagement element starts generating the transmission capacity.
