Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/029549
Kind Code:
A1
Abstract:
An electronic control device provided with: two controlling differential amplifier circuits; a diagnosing differential amplifier circuit; a first switch; a second switch; and a failure determining circuit that, when the first switch is in the diagnosing switch position, determines whether there is a failure in the diagnosing differential amplifier circuit and one of the controlling differential amplifier circuits on the basis on an output voltage which is output from the diagnosing differential amplifier circuit and one of the controlling differential amplifier circuits, and, when the second switch is in the diagnosing switch position, determines whether there is a failure in the diagnosing differential amplifier circuit and the other of the controlling differential amplifier circuits on the basis on an output voltage which is output from the diagnosing differential amplifier circuit and the other of the controlling differential amplifier circuits.
