ELECTRONIC CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To diagnose whether the drive time of a load is one as instructed.SOLUTION: An electronic control device includes: an arithmetic circuit 1 that outputs a drive instruction signal for performing drive instruction to a load 2; an FET 3 as a load drive circuit that drives the load 2 according to the drive instruction signal output from the arithmetic circuit 1; and a comparison circuit 4 that compares the waveform of the drive instruction signal and a load drive waveform according to the drive state of the load 2. The electronic control device diagnoses the drive time of the load 2 on the basis of the comparison result of the comparison circuit 4.
