ABSTRACT:
The load element state detecting portion72detects the completion of the filling of the hydraulic oil into the clutch62and the working limit of the accumulator64on the basis of the displacement of the spool valve element42. That is, since the completion of the filling of the hydraulic oil into the clutch and the working limit of the accumulator64are directly detected, so that the completion of the filling of the hydraulic oil into the clutch62and the working limit of the accumulator64can be detected with high precision regardless of differences among products and the time-lapse variation. Furthermore, they can be detected without equipping any special device to the hydraulic control circuit, and thus there is an advantage that the device construction is simple.
