    摘要: An automatic transmission including a torque converter and a multiple stage transmission gear mechanism. A hydraulically actuated brake and a hydraulically actuated clutch is provided for alternate engagement to select alternately one of two adjacent gear stages. In order to prevent gear shift shock, the engaging of the clutch or the brake is controlled so that the engaging rate is faster for a predetermined time period in an initial period of a gear shifting operation than in a remainder period. A control circuit is provided to monitor the gear shifting operation and modifying the predetermined time period in accordance with the results of the latest gear shifting operation and store the modified value for the use in a next gear shifting operation.

    摘要: A vehicle automatic transmission having a torque converter and a multiple stage transmission gear mechanism connected with the torque converter. The gear stage of the gear mechanism is selected in accordance with the vehicle operating condition. The transmission includes friction members. One of the friction members is engaged for a higher gear stage and disengaged for a lower gear stage whereas the other is disengaged for the higher gear stage and engaged for the lower gear stage. In shifting down from the higher gear stage to the lower gear stage, the other friction member is engaged after a predetermined time from the disengagement of the one friction member.

    摘要: A vehicle automatic transmission including a torque converter, a multiple stage transmission gear mechanism connected with the torque converter and a hydraulic control circuit for automatically selecting one of gear stages of the transmission gear mechanism. The hydraulic control circuit includes a kickdown control device which functions to shift down the gear mechanism when the engine control foot pedal is substantially fully depressed. Depending on the vehicle running condition, the kickdown control device shifts down the gear mechanism by two gear stages. The hydraulic circuit includes control circuit which functions to shift down the gear mechanism at first by one gear stage and then by a further one stage after a certain time delay when a two stage shift down is required.

    摘要: In a constant-speed cruising control system for a vehicle in which the throttle opening is feedback-controlled according to the difference between the actual vehicle speed and a desired vehicle speed so that the actual vehicle speed matches the desired vehicle speed, the vehicle speed is constantly detected when it increases in response to a driver's command, and the throttle valve is controlled so that the throttle opening converges on a target throttle opening which is predetermined according to the vehicle speed. The target throttle opening is corrected according to the running condition of the vehicle so that the vehicle speed is increased at a constant acceleration irrespective of the running condition of the vehicle.
