Patent ID: 8483905

Claim:
An energization control apparatus for a controlled vehicle component comprising: switching means disposed on a substrate and generating heat when supplying electric current from a power supply to a controlled vehicle component; a temperature-sensitive element disposed on the substrate; and anomaly detection means for detecting an anomaly of the temperature-sensitive element, wherein the anomaly detection means comprises: temperature-difference calculation means for acquiring a first physical quantity containing information regarding temperature of the temperature-sensitive element before startup of a vehicle or within a fixed period after the startup, and for acquiring a second physical quantity containing information regarding the temperature of the same temperature-sensitive element after elapse of a predetermined wait time from the time of acquisition of the first physical quantity, and for calculating a difference between the first physical quantity and the second physical quantity; and sensitivity anomaly determination means for determining, from the difference, an anomaly of the temperature-sensitive element associated with sensitivity to a temperature to be measured.
