<p>On the basis of the result of first target recognition processing by a beam recognition unit and the result of second target recognition processing by an image recognition unit, an axis deviation detection device for a beam sensor calculates the proportion of the number of times at least one preceding vehicle traveling in front of a vehicle was recognized in both the first target recognition processing and the second target recognition processing to the number of times the at least one preceding vehicle was recognized in at least image recognition processing, and according to the value of the calculated proportion, detects an axis deviation from a designed beam axis position of a beam axis of the beam sensor in a vertical plane including the beam axis.</p> |
