Abstract
A sensor abnormality determining apparatus is configured to determine an abnormality in a sensor apparatus, which is used to recognize a surrounding environment of a vehicle and which includes a heater for heating a cover. The sensor abnormality determining apparatus is provided with: a detector configured to detect a temperature of the heater; an estimator configured to estimate a temperature of the heater on the basis of a speed of the vehicle and an outside air temperature; and a determinator configured to determine an abnormality in the sensor apparatus on the basis of the detected temperature and the estimated temperature.
