PROBLEM TO BE SOLVED: To provide an electronic control device that includes a crank counter capable of improving calculation accuracy of a crank position by performing counting-up even followed by speed change even in acceleration/deceleration.SOLUTION: An electronic control device includes a crank counter configured to acquire a crank position between crank angle signals. The crank counter determines a time corresponding to a minimum count width up to a next crank edge, as an inclination value, and acquires a crank position up to the next crank edge on the basis of the inclination value. The crank counter further calculates acceleration of the crank edge on the basis of the time interval of the crank edge, and reflects the acceleration to the inclination value.SELECTED DRAWING: Figure 2 |
