    摘要: An exemplary control device includes an input torque detection unit that detects an input torque input to the input shaft; and a controller that: determines torque distribution of two of the friction engagement elements that form the shift speeds; and calculates a transmission torque of the two friction engagement elements based on the input torque and the torque distribution and sets the engagement pressure to obtain a torque capacity that can transmit the transmission torque, wherein the controller sets the engagement pressure such that slippage does not occur in the two friction engagement elements in a state where engagement of the two friction engagement elements forms the shift speeds and such that, even if an additional friction engagement element engages based on the line pressure while the two friction engagement elements are engaged, one of the three friction engagement elements is caused to slip.

    摘要: When the driver makes a request for switching the shift range to the P range despite that the vehicle has not yet stopped completely, the wheel cylinder pressure is maintained at a brake hold pressure Ph for a while, rather than switching the shift range to the P range immediately. At this time, more specifically, the wheel cylinder pressure is maintained at the brake hold pressure Ph for a brake hold duration Δt within which the vehicle is estimated to stop, and when the brake hold duration Δt has passed, the shift range is switched to the P range. After the lock mechanism is actuated to establish the P range, the wheel cylinder pressure is gradually reduced from the brake hold pressure Ph at a given pressure reducing gradient.

    摘要: A control system for an automatic transmission includes a clutch adapted to be applied when a forward running range is selected, for transmitting the rotation of an engine to a speed change unit. A hydraulic servo applies the clutch responsive to feed of an oil pressure and a control unit controls the oil pressure fed to the hydraulic servo. The control unit brings the clutch into a substantially released state by lowering the oil pressure of the hydraulic servo if the stop state of a vehicle is detected by a stop state detector and applies the clutch if the stop state of the vehicle is not detected with the clutch released. The oil pressure fed to the hydraulic servo is raised according to a second mode when the accelerator pedal is depressed, in preference to a first mode in which a brake pedal is released, if the accelerator pedal is depressed when the stop state of the vehicle is not detected because the accelerator pedal is released so that the engagement of the clutch has not started.

    摘要: In a creep preventing device of the type in which an oil discharge passage communicating with an oil tank is branched from an oil feed passage for supplying an operating oil pressure to a starting clutch or other starting elements of an automatic transmission of a vehicle and an electromagnetic valve capable of closing the oil discharge passage under the demagnetized state and opening it under the excited state is disposed in the oil discharge passage, a method of controlling the creep preventing device is characterized in that when the electromagnetic valve is returned from the excited state to the demagnetized state, the electromagnetic valve is chopped a predetermined number of times. This method can re-connect the starting elements smoothly without incurring any shock.

    摘要: A drive arrangement for motor vehicles, especially for passenger motor vehicles, having an automatically shifting transmission and a mechanism for raising the idling rotational speed of the driving engine during a warm-up phase. The automatically shifting transmission includes a servo-device which, in a first position of a command slide valve, is adapted to be shifted into a position for a first speed range and, in a second position of the command slide valve, is adapted to be shifted into a position for a second speed range. A kickdown solenoid valve acting on the command slide valve is provided which, during actuation of a kick-down switch, passes over into a down-shifting position. A shifting-up relay opening, when energized, is connected in parallel with the kick-down switch whereby a switch is connected in the energizing circiuit of the shifting-up relay which closes the energizing circuit of the shifting-up relay upon actuation of a brake pedal in such a manner that the kick-down solenoid valve passes over into a shifting-up position during the actuation of the brake pedal.
