Abstract

An in-vehicle electronic control apparatus includes a monitoring control circuit configured such that a monitoring control circuit unit transmits question information; a main control circuit unit transmits answer information generated by a microprocessor; the monitoring control circuit unit applies an addition and subtraction correction to a value of a first present-value memory in response to a result of a comparison between correct-solution information stored in a data memory and the answer information; and when the accumulated present value exceeds an abnormality determination threshold value, the monitoring control circuit unit generates a first abnormality detection signal so as to initialize and restart the microprocessor, and variably sets the abnormality determination threshold value or an abnormality determination time, based on selectively applied setting constants generated with pattern switches.
