ABSTRACT:
In a control system for controlling the occurrence of an abnormality in one of the computers mounted on a motor vehicle, a decision is made based upon whether a sub CPU has been reset. In the case where the sub CPU is reset by an abnormality or a malfunction, a failsafe mode flag is set and control data are transmitted again from the main CPU to the sub CPU. The interruption is finished after the control command signal is transmitted to the sub CPU. At this time, if the failsafe mode flag is set, the failsafe control is executed. If the failsafe mode flag is not set, the normal control is executed. Therefore, even if the control data in the RAM of the computers are destroyed by the occurrence of an abnormality or malfunction, the system can regain normal operation immediately.
