PROBLEM TO BE SOLVED: To prevent breakage of an engine by properly controlling a fuel without making a mistake in determining a crank angle even when any abnormality occurs in a function of an A/D converter or the like inside a microcomputer. ! SOLUTION: An electronic control device for a vehicle includes a crank angle detecting section (3001), a cycle measuring section (3003) for measuring an interruption processing cycle, an interruption processing time measuring section (3004) for measuring an interruption processing time, a fuel cut determining section (3005) for determining the execution of fuel cut when the interruption processing time becomes longer than a time obtained by subtracting a margin from the interruption processing cycle, a cylinder determining section (3002) for determining whether a present interruption processing cycle is fuel injection timing or not, and a fuel output section (3006) for controlling a fuel injection valve by setting a valve opening time of the fuel injection valve to 0 |
