PCT No. PCT/JP93/01104 Sec. 371 Date Apr. 1, 1994 Sec. 102(e) Date Apr. 1, 1994 PCT Filed Aug. 5, 1993 PCT Pub. No. WO93/01104 PCT Pub. Date Aug. 5, 1993.The invention involves stopping the operation of an internal combustion engine, when actual vehicle deceleration is detected after a vehicle deceleration operation. Alternatively, under conditions wherein it is possible to shut off fuel supply at the time of the deceleration operation, the invention involves stopping the operation of the engine by shutting off the fuel supply to some cylinders, and then shutting off the fuel supply to all cylinders when actual vehicle deceleration is detected. Since the fuel supply to the engine is timed to be shut off when the vehicle is decelerated, the speed is reduced smoothly without an accompanying large torque change. Thus, vehicle ride comfort and fuel consumption can be improved.
