Abstract

PURPOSE:To prevent malfunction by changing the timing of entering the interruption handling routine when the timing of interrupt operation conducted by an interruption timer is not within a permissible range, and stopping processing for entering the timer interruption handling routine when the frequency reaches a designated value. CONSTITUTION:In ECU to which output signals of a torque sensor 40 and a speed sensor SP are input, there are provided a timer (interruption timer) Timer 1 for obtaining the timing of interruption and a timer (free-run timer) Timer 2 for measuring the timing of interruption, which are driven by CPU. The timing of interruption operation conducted by an interruption timer is supervised, and when the timing is not within a permissible range, the timing of entering the timer interruption handling routine of the interruption timer is changed. If the timing is not within a required range, the frequency is counted by a counter for interruption abnormality frequency, and when the count value reaches a designated value, the processing for entering the time interruption handling routine is stopped.
