摘要： An oil pressure control device, which changes a range of a vehicle transmission includes: a pressure adjusting device that engages or releases forward and reverse frictional-engagement devices by adjusting an oil pressure supply, a sensor that detects a range selected by a vehicle driver, and a controller that controls the clutch pressure adjusting device based on a signal from the sensor. When the stop range is selected after selecting the reverse (forward) range, a forward (reverse) range is selected. After supplying an initial oil pressure to the forward (reverse) frictional-engagement device, the pressure adjusting device is controlled so that the pressure decreases from the initial oil pressure to a predetermined oil pressure. Subsequently, the oil pressure is initially increased at a small increase rate from the predetermined oil pressure. After a predetermined time period has elapsed, the pressure adjusting device increases the oil pressure at a large increase rate.

摘要： A lock-up clutch control apparatus for controlling a lock-up clutch (6) provided in a torque converter (5) installed between an engine (3) and a transmission (4), is disclosed. The lock-up clutch control apparatus has a differential pressure generator (7,8) which engages, causes a slip of or disengages the lock-up clutch by adjusting the differential pressure supplied to the lock-up clutch (6); a sensor (11/15) for detecting a rotational speed of the engine; a sensor (16) for detecting an input rotational speed to the transmission; and a controller (1). The controller (1) conducts proportional integration control by using a command signal to the differential pressure generator (7,8), so that an actual slip rotational speed, which is the difference between the engine rotational speed (Np) and input rotational speed (Ni) to the transmission, becomes a target slip rotational speed (Nt). The controller is programmed to conduct integration accumulating the difference (ΔN) between the target slip rotational speed (Nt) and the actual slip rotational speed (SN); to determine whether the accumulated integrated value (I) is equal to or higher than a predetermined integration value (It); and to stop the integration when the accumulated integration value (I) is equal to or higher than the predetermined integration value (It).
