Abstract
PURPOSE: To permit low speed setting and improve fuel cost by allowing a fuel cut signal to disappear irrespectively of other conditions in case of a speed change to the lowest step of gear change gear, in a car with automatic transmission equipped with a fuel cutting device on an engine.
CONSTITUTION: An idle switch 72 outputs the idle signal S1 at L level in accelerating pedal release and at H level in other cases, and a brake switch 73 outputs the brake signal SB at L level in braking and at H level in other cases, and the both signals S1 and SB are supplied into the NOR gate 233 of a control memory circuit 221. On the other hand, the third speed signal S3 of an automatic transmission is reversed at the NOR gate 234 and supplied into the NOR gate 233. Therefore, all the inputs 3 due to accelerating pedal release and brake operation are at L level even in the third speed traveling, and the H level signal is output, and an OR gate 235 outputs the fuel cut signal S cut. Thus, a fuel cut is performed unconditionally.
