Abstract

PURPOSE: To prevent creep from occurring to a vehicle even when the vehicle is stopped with a manual valve in a D-range position by engaging, in a hydraulic vehicle control circuit, speed shift stages with frictional elements.
CONSTITUTION: When a vehicle running with setting made to D-range is operated for stop and the running speed thereof comes down almost to stop level, governor pressure lowers substantially to 0, and a spool valve 114 is transferred leftward by the energization force of a spring 112 to close a boat 115 and at the same time communicates a boat 118 to a discharge oil boat so that line pressure is discharged via an oil passage 116. Therefore, the spool valve 90 is transferred, by the hydraulic pressure working between lands 84 and 86, to rightward to a position where by the hydraulic pressure working between lands 84 and 86 the hydraulic pressure and the energization force of a spring 88 balance with each other, and the land 80 releases the boat 94, engages a brake 58 and reduces the hydraulic pressure of a clutch 28. Consequently, a speed change gear is set in D-range stop position and creep is avoided.
