PCT No. PCT/JP88/00144 Sec. 371 Date Sep. 28, 1988 Sec. 102(e) Date Sep. 28, 1988 PCT Filed Feb. 13, 1988 PCT Pub. No. WO88/06236 PCT Pub. Date Aug. 25, 1988.An engine control method for a vehicle is disclosed in which operation of an engine is optimally controlled in an entire operating range thereof without causing any undesirable delay in control operation. To this end, operating conditions of the engine are sensed through the use of various sensors and control signals are calculated based on the sensed engine operating conditions in a plurality of steps through the use of a microcomputer so that the operation of the engine is optimized by the use of the control signals thus calculated. In one embodiment, a first step and a second step of the plurality of steps are alternately calculated and omitted every other time the control signals are calculated while an operating parameter of the engine operates in a specified operating range in which variations in the sensed operating conditions of the engine are limited. In another embodiment, a third step of the plurality of steps is omitted every other time the control signals are calculated while an operating parameter of the engine operates in the specified operating range in which variations in the sensed operating conditions of the engine are limited. |
