PROBLEM TO BE SOLVED: To prevent belt sliding and a starting delay, by properly controlling a linear solenoid valve for controlling supply oil pressure to a starting clutch when returning to an idle stop.SOLUTION: This control device includes the normally opening linear solenoid valve SLS for controlling the supply oil pressure to the starting clutch B1 and a solenoid valve driving circuit 100 for controlling the linear solenoid valve in response to a plurality of electric current-oil pressure characteristics. When returning from the idle stop, oil pressure generated by an oil pump is detected, and when its generating oil pressure is less than an allowable value, an indicator current to the linear solenoid valve is determined by selecting the electric current-oil pressure characteristics of increasing valve opening of the linear solenoid valve. |
