摘要： For a 2.fwdarw.1 shift, a timing solenoid valve SL5 is maintained at a duty cycle of 0% (off) for an interval TE=1.5 sec from the initiation of the shift operation and then the duty cycle is changed to 100% (on) after the TE interval so that an oil pressure of a brake B.sub.2 is maintained low during the shift operation while the oil pressure is increased to a high oil pressure for transfer of a maximum torque used in the first speed range upon completion of the shift operation. In response to a switching of a shift lever from D or S range to L range, the timing solenoid valve SL5 is energized with a duty cycle of 100% (on) at 2 sec after such switching to provide a high oil pressure for transfer of the maximum torque, thus preventing a shift shock from occurring as a result of a switching from D or S to L range. Since a control over the oil pressure through the timing solenoid valve SL5 during the shift operation takes place by switching an energization level of the solenoid SL5, the oil pressure can be switched in an accurate manner.

摘要： The rotational speed of an engine Ne and a drum rotational speed Nt of a clutch Cl are compared against each other to determine a power on/off. For a 2.fwdarw.3 and a 2.fwdarw.4 shift in the power off condition, a timing solenoid SL5 is turned on (duty cycle of 100%) to accelerate the termination of a preceding speed range, thus increasing a time delay between such termination and the activation of a new speed range to be established. For other shifts, a time difference between the termination of a preceding speed range and the activation of a new speed range to be established is adjusted, by energizing the solenoid SL5 in accordance with the throttle opening .theta. and the vehicle speed No such that SL5 is energized with a high duty cycle for a longer .theta. and with a low duty cycle for a smaller .theta..

摘要： An electronically controlled automatic transmission system including an automatic transmission having a plurality of clutches and brakes activated by application of a fluid pressure to change the gear ratio by engagement and disengagement of the clutches and brakes, a fluid pressure switching device for controlling the application of the fluid pressure to the clutches and brakes, and an electronic controller for changing the engagement and disengagement of the clutches and brakes by driving the fluid pressure switching device in accordance with the running condition of the vehicle, the electronic controller also controlling the speed of engagement of a clutch or brake which is to be engaged. The electronic controller includes a torque sensor for detecting the torque of the output shaft of the automatic transmission, and an engagement speed correcting device for correcting the speed of engagement of a clutch or brake which is to be engaged on the basis of the detected torque. If the condition of double engagement is judged to be improper in the process of gear-shifting, the speed of engagement of the clutch or brake to be engaged is automatically corrected so that the condition of double engagement is shifted to an optimal one by feedback control. Thus, the shock applied to the vehicle during a gear-shifting operation is reduced.

摘要： A hydraulic control apparatus for an automatic transmission has friction elements for performing a downshift by releasing one friction engaging element and engaging another. The apparatus includes duty control valves connected to the friction engaging elements, duty solenoid valves connected to oil lines for supplying pilot hydraulic pressure to the duty control valves, and control means. In a case where a release duty signal is outputted to one duty solenoid valve to control the pilot hydraulic pressure to thereby release the one friction engaging element, and downshift is a power-on downshift, the control means raises the duty ratio of the other duty solenoid valve to a predetermined valve to raise engaging hydraulic pressure supplied to the other friction element when rotational speed of the transmission input shaft is greater than a difference between the product of output shaft rotational speed and low-side gear ratio and a rotational speed commensurate with a delay in engine speed upturn.
