Abstract
A sensor abnormality estimation device determines whether or not a position and a speed of a sensor-mounted vehicle at an intersection fulfill a predetermined performance condition. When the position and the speed fulfill the performance condition, the sensor abnormality estimation device acquires recognition results obtained by two of a plurality of external sensors, for a target object at a designated position associated with the position of the sensor-mounted vehicle. The sensor abnormality estimation device then acquires a degree of coincidence between the recognition results, and determines that there is an abnormality in at least one of the two external sensors when the degree of coincidence is lower than a predetermined determination value.
