Abstract

PURPOSE: To improve the fuel consumption of a car with the specification of an automatic transmission by permitting compulsory down-shift only when the conditions to permit compulsory down-shift for an automatic transmission are ready at a prescribed speed or more.
CONSTITUTION: An idle switch 72 and a brake switch 73 are installed in the lock- up control circuit for an automatic transmission. The switch 72 is closed during release of an accelerating pedal, and the switch 73 is closed when a brake pedal is stepped-in. If the brake pedal is stepped-in during coasting run when the accelerating pedal is released with the automatic transmission in the third speed the idle signal S1 at L level and the brake signal SB are input into an NOR gate 230, and the output signal of a car speed comparison circuit 222 in the case when the car speed is larger than the speed of the car to which fuel should be supplied again and the third speed signal S3 are respectively reversed, and input at L level into a gate 230. The gate 230 energizes a solenoid 137a through a flip-flop circuit 239 and a transistor 240 to operate down-shift.
