Patent ID: 8707924

Claim:
A control device for an engine provided with a starter including a second gear that can be engaged with a first gear coupled to a crankshaft; an actuator causing, in a driven state, said second gear to be moved to a position where said second gear is engaged with said first gear; and a motor causing said second gear to be rotated, said engine being provided with a detection unit for detecting rotation of said crankshaft, said control device being configured to determine whether said actuator is driven, determine whether said motor is driven, update a value of a crank angle of said crankshaft recognized by said control device based on a signal from said detection unit when said control device determines that said actuator is driven and said motor is driven, and inhibit update of the value of the crank angle based on the signal from said detection unit when said control device determines that said actuator is driven and said motor is not driven, wherein said control device inhibits update of the value of the crank angle during a time period from a time when said control device determines that said actuator is driven and said motor is not driven until a time when said actuator is driven and said motor is driven.
