TRANSMISSION HYDRAULIC CONTROLLER FOR IDLE STOP VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a transmission hydraulic controller for an idle stop vehicle capable of preventing slip of a driving force transmission element in a transmission even if the oil pressure from a pressure adjusting valve drops abruptly when restarting an engine. SOLUTION: This transmission hydraulic controller is provided with the idle stop vehicle capable of automatically stopping the engine during stop of the vehicle when the transmission can transmit driving force and automatically restarting the engine when the vehicle starts. This controller is provided with a hydraulic pump 8 for outputting oil pressure in the interlocking relationship with the engine, the pressure adjusting valve for adjusting oil pressure outputted from the hydraulic pump 8 and supplying it so as to transmit driving force to the driving force transmission element in the transmission, and a pressure adjusting command means for outputting a control command for obtaining oil pressure adjusted by the pressure adjusting valve. The pressure adjusting command means is a means having a pressure adjusting command part when restarting the engine for outputting a control command for obtaining oil pressure by a higher value than a value at ordinary running time when restarting the engine automatically.
