ABSTRACT:
An engine controller includes various sensors for detecting a degree of throttle opening .theta. and a degree of accelerator opening .alpha. and a control unit 5 for determining the control amount .theta.c of a throttle actuator 1 from operating states, the control unit includes an A/D converter 70 for A/D converting respective degrees of opening at a predetermined resolving power, means 71 for calculating a target degree of throttle opening .theta.1 at a resolving power higher than the predetermined resolving power, means 72 for calculating a target degree of throttle opening .theta.2 at the predetermined resolving power in accordance with the target degree of throttle opening .theta.1 and means 73 for calculating a control amount in accordance with the target degree of throttle opening .theta.2, the target degree of throttle opening .theta.2 includes two points which are determined by the predetermined resolving power and control amount calculation means repeatedly controls the throttle actuator at a predetermined cycle using the target degree of throttle opening .theta.2 as the control amount under predetermined operating conditions. With this arrangement, the engine controller having a high speed and a pinpoint accuracy can be provided at a less expensive cost without using an expensive A/D converter.
