PURPOSE:To prevent a malfunction of an automobile use computer by deciding an interrupting inhibition state or not in a prescribed step, when a regular processing routine is being executed, and making the processing pass through a branch routine for releasing the inhibition state, in case of the interrupting inhibition state. CONSTITUTION:First of all, in a step S1, the first processing routine I which is given by dividing the regular processing routine into prescribed pieces is executed. In a step 2, whether the processing of this time is in an interrupting inhibition state or not is decided, and in case of the interrupting inhibition state, its inhibition state is released in the next step S3. Also, if necessary, after a step S4 for storing a fact that a malfunction has occurred (the interrupting inhibition has been executed) in a RAM, or in the step 2, when it is decided that the processing is not in the interrupting inhibition state, the processing enters into the subsequent processing routine II in a step S5. In such a way, it is eliminated that a CPU disregards an interrupting request, and a serious malfunction is prevented. |
