Abstract
A control system for an automatic transmission ( ) includes an oil pressure control mechanism ( ) for supplying an oil pressure to the transmission ( ), and sensor ( ) for detecting the oil pressure supplied from the oil pressure control mechanism ( ) to the transmission ( ). System controller ( ) calculates a maximum torque transmittable by the transmission ( ) based on a speed ratio of the transmission ( ) and the detected oil pressure; calculate an engine torque reduction amount from the difference between the torque being inputted into the transmission ( ) and the maximum transmittable torque; and reduce the torque of an engine ( ) according to the engine torque reduction amount.
