PROBLEM TO BE SOLVED: To precisely detect an analog sensor signal value (sensor value) at the time when a crank angle becomes a specified command angle on an engine control device. SOLUTION: The engine control device A/D converts the sensor value for each of constant time Tint during a sampling period of time from rising timing of a crank angle signal immediately before the crank angle becomes the command signal to rising timing of the crank angle signal immediately after the crank angle passes the command angle to detect the sensor value at the time of crank angle = command angle and measures time T1, T2 of the both timing. Thereafter, time T of crank angle = command angle is computed from the both time T1, T2, an angle B from the crank angle to the command angle at the former timing (time 1), an A/D converted value at a time nearest to the time T is selected from the A/D converted values for the sampling time and it is made a target sensor value.
