    摘要: A transmission control system for controlling a transmission. The system has a main transmission with a speed changing mechanism and an output shaft, a substransmission connected to the output shaft, and a control system for receiving outputs from a number of sensors which sense the running state of the vehicle. The control system itself has two outputs, there being two separate hydraulic controls connected to the two system outputs, respectively. The two hydraulic controls control the speed changing mechanisms of the main and subtransmissions, respectively. Also provided is a hydraulic pressure source which supplies a working fluid to the two hydraulic controls. The control system determines whether the main and subtransmissions are in a transient period of the speed changing operation and, as long as one of the two transmissions is in the transient period, inhibits the speed changing operation of the other transmission.

    摘要: A hydraulic control system for an automatic transmission has an inhibitor valve which comprises a change-over valve having a first set position and a second set position and functioning to supply and discharge a hydraulic pressure to and from a hydraulic servomechanism for a friction engaging element through its movement between the first and second set positions; an arrangement for urging the change-over valve to the first set position; a plunger having a first set position and a second set position and functioning to bring the change-over valve into the second set position when the plunger is urged to the second set position. The inhibitor have functions to perform the supply and discharge of the hydraulic pressure to and from the hydraulic servomechanism in accordance with a first hydraulic signal and a second hydraulic signal through an arrangement which produces the first hydraulic signal for urging the change-over valve to the second set position and urging the plunger to the first set position. An arrangement produces the second hydraulic signal for urging the plunger to the second position; and an arrangement delays a discharge of the second hydraulic signal.

    摘要: The transmission control device of the present invention comprises a main transmission and a sub transmission and has a first hydraulic switching device which is controlled by automatic operation for setting the shift range of the sub transmission and a second hydraulic switching device which controls the hydraulic pressure produced by the first hydraulic switching device, prohibits any speed change of the shift range, and controls other functions of the sub transmission. By the above-described structure, the transmission control device of the present invention is able to prohibit speed changes in the shift range and to control other functions of the sub transmission regardless of the automatic operation of the sub transmission, because the second hydraulic switching device can control the hydraulic pressure produced by the first hydraulic switching device even if the shift mechanism of the sub transmission is being operated by the first hydraulic switching device.
