    摘要: A device and method for determining whether a malfunction is present in a drive circuit, which drives an electric device that generates counter-electromotive force, when all gates in the switching elements of the drive circuit are blocked. After the gates are blocked, the temperature of the switching elements is monitored and the presence of a malfunction is determined based on the detected temperature of the switching elements. A malfunction is determined to be present when the detected temperature equals or exceeds a predetermined temperature; the change in the detected temperature equals or exceeds a predetermined value; or the rate of change in the detected temperature equals or exceeds than a predetermined rate. Thus, it can be appropriately determined whether the gates in the drive circuit are appropriately blocked and minimize the influence of any malfunctions on other elements outside of the drive circuit.
