Apparatus for detecting axial misalignment
First Claim
1. A diagnostic apparatus of a beam sensor installed in a vehicle, the beam sensor transmitting a probing beam and receiving a reflected beam based on the probing beam, the diagnostic apparatus comprising:
- an obtaining means for obtaining horizontal misalignment information indicative of whether a horizontal misalignment exists, the horizontal misalignment being misalignment of the probing beam with respect to a designed beam axis position in a horizontal direction, the horizontal direction corresponding to a width direction of the vehicle;
a diagnostic means for diagnosing whether vertical misalignment exists, the vertical misalignment being misalignment of the probing beam with respect to the designed beam axis position in a vertical direction, the vertical direction corresponding to a height direction of the vehicle; and
a determining means for;
determining, based on the horizontal misalignment information, whether the diagnostic means executes diagnosis of the vertical misalignment;
causing the diagnostic means to execute diagnosis of the vertical misalignment upon the horizontal misalignment information representing that no horizontal misalignment exists; and
disabling the diagnostic means from executing diagnosis of the vertical misalignment upon the horizontal misalignment information representing that horizontal misalignment exists.

Abstract
A diagnostic apparatus includes an obtaining unit for obtaining horizontal misalignment information indicative of whether there is horizontal misalignment in a probing beam. The diagnostic apparatus includes a diagnostic unit for diagnosing whether there is vertical misalignment. The vertical misalignment is misalignment of the probing beam with respect to a designed beam axis position in a vertical direction. The vertical direction corresponds to a height direction of the vehicle. The diagnostic apparatus includes a determining unit for determining, based on the horizontal misalignment information, whether the diagnostic unit executes diagnosis of the vertical misalignment. The determining unit causes the diagnostic unit to execute diagnosis of the vertical misalignment upon the horizontal misalignment information representing that there is no horizontal misalignment. The determining unit disables the diagnostic unit from executing diagnosis of the vertical misalignment upon the horizontal misalignment information representing that there is horizontal misalignment.

7. A method for detecting axial misalignment of a beam sensor installed in a vehicle, the beam sensor transmitting a probing beam and receiving a reflected beam based on the probing beam, the method comprising:
-
obtaining horizontal misalignment information indicative of whether a horizontal misalignment exists, the horizontal misalignment being misalignment of the probing beam with respect to a designed beam axis position in a horizontal direction, the horizontal direction corresponding to a width direction of the vehicle; diagnosing whether vertical misalignment exists, the vertical misalignment being misalignment of the probing beam with respect to the designed beam axis position in a vertical direction, the vertical direction corresponding to a height direction of the vehicle; determining, based on the horizontal misalignment information, whether diagnosis of the vertical misalignment is performed; executing diagnosis of the vertical misalignment upon the horizontal misalignment information representing that no horizontal misalignment exists; and disabling diagnosis of the vertical misalignment upon the horizontal misalignment information representing that horizontal misalignment exists.

8. A system for detecting axial misalignment of a beam sensor installed in a vehicle, the beam sensor transmitting a probing beam and receiving a reflected beam based on the probing beam, the system comprising:
-
a central processor; a non-transitory computer-readable storage medium; and a set of computer-executable instructions stored on the non-transitory computer-readable storage medium that cause the central processor to implement; obtaining horizontal misalignment information indicative of whether a horizontal misalignment exists, the horizontal misalignment being misalignment of the probing beam with respect to a designed beam axis position in a horizontal direction, the horizontal direction corresponding to a width direction of the vehicle; diagnosing whether vertical misalignment exists, the vertical misalignment being misalignment of the probing beam with respect to the designed beam axis position in a vertical direction, the vertical direction corresponding to a height direction of the vehicle; determining, based on the horizontal misalignment information, whether diagnosis of the vertical misalignment is performed; executing diagnosis of the vertical misalignment upon the horizontal misalignment information representing that no horizontal misalignment exists; and disabling diagnosis of the vertical misalignment upon the horizontal misalignment information representing that horizontal misalignment exists.
