摘要： The present invention provides inspection of a transmission with higher precision and in a shorter period of time. Before a finished A/T is inspected, a V/B ASSY and an ECU are inspected together by a V/B tester in a subsidiary line. A solenoid current command value (a characteristic value inherent in the A/T) for a linear solenoid of the V/B ASSY is corrected and written into the ECU through CAN communication. Spring load of a return spring SP and stroke of the piston of a hydraulic servo for a frictional engagement element are measured. Actually measured values or corrected values of the spring load and the stroke are stored. In the final inspection of the A/T a finished-product tester reads the stored characteristic values and transmits them to the ECU integrated with the A/T through CAN communication. The characteristic values are then written into the ECU. The finished-product tester inspects the finished A/T product, using the characteristic values thus written into the ECU.

摘要： In the case where a cooperative gear change control of an automatic transmission is executed on the basis of information with respect to a condition around a vehicle or in front of a vehicle, in a cooperative gear change control means, a gear change of the automatic transmission is directly determined on the basis of actual curve information and road surface inclination information in accordance with a previously stored downshift map, and a gear stage is switched such that a determined gear change is executed. Therefore, it is possible to directly obtain the gear stage or the gear ratio corresponding to the curve of the road and the inclination of the road surface.

摘要： In an automatic transmission, torque shocks are effectively reduced in specific downshifting conditions where relatively strong engine braking occurs as a result of downshifting. When a downshift command to the automatic transmission is detected when an accelerator pedal is not depressed, a valve opening command is issued to a throttle valve so that engine output will have increased by the time the downshifting action of the automatic transmission actually begins, ignition timing is delayed so that an increase in engine output resulting from the opening of the throttle valve by a throttle valve control means is offset for a period starting at the time the engine output actually increases as a result of the opening of the throttle valve by the throttle valve control means and ending at the time the downshifting action of the automatic transmission actually beings, and the ignition timing delaying is cancelled upon initiation of the downshifting action of the automatic transmission.

摘要： A hydraulic control unit configured to improve energy efficiency is provided. The hydraulic control unit is comprised of: a feeding passage that delivers fluid from at least any of an oil pump and an accumulator storing hydraulic pressure to an actuator; a draining passage that discharge the fluid from the actuator to a drain spot; and a discharging means that is configured to selectively discharge the fluid from the actuator to the accumulator through the feeding passage, if the fluid has to be discharged from the actuator and a pressure of the accumulator is lower than that of the actuator.
