Abstract

PURPOSE: To an automatic transmission of the hydraulic control type, to reduce unpleasant feeling of deceleration through automatic shift-down operation only when the vehicle is running at an acceleration above a fixed value and the driver steps off the accelerating pedal and steps on the brake pedal.
CONSTITUTION: The automatic transmission comprises an idle switch 29 capable of detecting accelerating pedal release, a brake switch 31 capable of detecting actuation of the brake pedal and a running speed sensor 26. The output of the running speed sensor 26 is introduced to a comparator 35 via an acceleration detecting circuit 33 to compare the output of the running speed sensor 26 with the output of an acceleration setting circuit 34. When the acceleration exceeds a set value, a low- level signal is applied to one of the terminals of an NOR gate 36. The output of the idle switch 29 through a timer 37 and the output of the brake switch 31 are applied to the other terminal of the NOR gate 36. A down-shift solenoid 25 disposed in the transmission is actuated through an FF40 when a high-level signal is produced from the gate 36.
