Vehicle device controller and temperature sensor anomaly detection method therefor

摘要

There is provided a controller for controlling a vehicle device, which includes a circuit board (10b) having mounted thereon a control circuit (19) that controls operations of the vehicle device, a first temperature sensor (151) mounted on a first specific region (10c) of the circuit board (10b) to output a first signal responsive to a temperature of the first specific region (10c) of the circuit board (10b) and a second temperature sensor (152) mounted on a second specific region (10d) of the circuit board (10b) to output a second signal responsive to a temperature of the second specific region (10d) of the circuit board (10b). The control circuit (19) has an anomaly detection portion that judges the occurrence or non-occurrence of an output anomaly in the first temperature sensor (151) based on the first and second signals of the first and second temperature sensors (151, 152).
