To provide an energization control apparatus for a controlled vehicle component which includes a temperature-sensitive element and which can detect an anomaly of the temperature-sensitive element more accurately. An energization control apparatus (30) includes an FET (32) (switching means), a thermistor (34) (temperature-sensitive element), and anomaly detection means (36). The anomaly detection means (36) includes temperature-difference calculation means (45) and sensitivity anomaly determination means (41). The temperature-difference calculation means (45) acquires a first physical quantity containing information regarding the temperature of the thermistor (34) before startup of a vehicle or within a fixed period after the startup, acquires a second physical quantity containing information regarding the temperature of the thermistor (34) at the time when a predetermined wait time has elapsed from the time of acquisition of the first physical quantity, and calculates the difference between the first physical quantity and the second physical quantity. The sensitivity anomaly determination means (41) determines, from the difference, an anomaly of the thermistor (34) associated with its sensitivity to a temperature to be measured. |
