Abstract
A method of controlling a hydraulic actuator which controls the rotational phase angle of the fuel injection pump for the automobile. A satisfactory exhaust gas composition and an appropriate fuel consumption during a warm-up period of the engine are achieved when the oil temperature in the hydraulic actuator is low. The control method for the hydraulic actuator includes the steps of detecting the temperature corresponding to the oil temperature, comparing the detected temperature with the predetermined reference temperature, and making the application period of the command pulse signal for driving the hydraulic actuator longer than the predetermined length when the detected temperature is lower than the predetermined reference temperature.
