Abstract
PURPOSE: To prolong fuel cut time and reduce fuel cost by transferring a drive at the highest speed section to coasting operation and furthermore by downshifting a transmission under driving conditions where a brake pedal is stepped down.
CONSTITUTION: An NOR gate 230 receives an idle signal S1 in L level and a brake signal S under driving conditions where the brake pedal must be stepped down during coasting. When the third speed is selected and the third speed signal S3 is at H level and the vehicle speed is V≥V4 (V4: vehicle speed to inject again the fuel when a torque converter is under lock up conditions), a vehicle speed comparison circuit 222 outputs H level signals from a gate. The two signals at H level are turned down to L level by NOT gates 237 and 238. A flip-flop circuit 238 outputs H level signals and energizes a downshift solenoid 137a. Then an OR gate 228 outputs H level signals and energizes a lock up solenoid 31.
