Abstract

PURPOSE: To provide optimal control of clutch of an automatic transmission, by controlling a solenoid valve for lock-up shift valve control through comparsion of traveling conditions with lock-up junction data in a memory circuit.
CONSTITUTION: Outputs of a speed sensor 22 and throttle valve sensor 23 are put in a discriminating circuit 25 to compare with output of a memory circuit 24. If the output of memory circuit 24 is larger than the other output, the discriminator 25 applies high outut to a solenoid valve control circuit 26 and energizes the solenoid valve 20. Since there is no pressure in an oil chamber 14, a spool 12 is shifted by a spring 11 of lock-up shift valve 10 to the right, and pressure oil flows through oil lines 8, 7, clutch 2, oil lines 6, 9 in this order to release the clutch 2.
