Abstract:
1. An electronic control system comprising: a microcomputer that generates a control signal for controlling a control object based on a control program stored in storage means; monitoring means, that executes abnormality monitoring processing, for monitoring the microcomputer to check whether the microcomputer is normal and halts the microcomputer and the control object when the microcomputer is determined to be abnormal; heavy-load program processing requesting means for outputting a heavy-load program processing request signal that requests the microcomputer to process a predetermined heavy-load program stored in the storage means when the microcomputer is in a state other than a predetermined normal control; monitoring halting means for halting the abnormality monitoring processing in response to an input of the heavy-load program processing request signal; and control prohibiting means for halting the control object on a safe side by blocking out the control signal of the microcomputer so as not to be transmitted to the control object in response to an input of the heavy-load program processing request signal when the abnormality monitoring processing is halted by the monitoring halting means.
