摘要： In controlling an automatic transmission in a vehicle by a combination of an electronic computer system and a hydraulic actuation system according to a principle of feedback control so that the electronic computer system computes a target control state for the hydraulic actuation system and the hydraulic actuation system is operated according to a difference between the target control state and a current control state thereof, the difference is modified by an amount which is decreased along with lapse of time so that the delay in the operation of the hydraulic actuation system is compensated for by a simulation that at the start of control the difference is beforehand increased for an amount which is gradually cancelled by a delay function of the difference itself as the delay in the operation of the hydraulic actuation system disappears. The difference may further be modified so that the modification is started with a time lag. The difference may further be modified by the rate of change of itself.

摘要： A hydraulic control circuit for an automatic transmission which has a plurality of hydraulic type frictional engagement elements for switching gear stages and a lockup clutch juxtaposed to a hydraulic power transmission device for transmitting engine power to the gearing. The hydraulic control circuit includes a lockup relay valve for switching oil pressure between an application side oil chamber and a release side oil chamber of the lockup clutch to apply and release the lockup clutch and a lockup switching valve for switching the lockup relay valve. A lockup control valve functions to increase the pressure difference between the application side oil chamber and the release side oil chamber at the time of application of the lockup clutch, as a signal pressure rises. A transient pressure control valve controls the transient pressure of a hydraulic frictional engagement element in accordance with the signal pressure. A single linear solenoid valve regulates the signal pressure fed both to the lockup control valve and to the transient pressure control valve. A signal pressure relay valve has a first output port connected to the lockup control valve and a second output port connected to the transient pressure control valve. The signal pressure relay valve is switched by first and second relay pressures to selectively switch the destination of the signal pressure which is regulated by the linear solenoid valve. When the signal pressure is fed to the accumulator control valve, a modulator oil pressure is fed to the lockup control valve.
