Abstract

An abnormality is detected in a sensor system mounted on a vehicle and including first and second external sensors for acquiring external information and an internal sensor for acquiring internal information. An error, occurring in an internal motion physical quantity based on the internal information, is estimated based on the external information, and the error is corrected. A first external motion physical quantity based on the external information acquired by the first external sensor, a second external motion physical quantity based on the external information acquired by the second external sensor, and the internal motion physical quantity in which the error is corrected by the correction block are compared to determine an abnormality in the sensor system.
