Patent ID: 8344940

Claim:
An apparatus for adjusting sensor vertical alignment, the apparatus comprising: a surface reflected wave measuring unit measuring signal intensity of a surface reflected wave reflected from a road surface on a basis of the reflected wave received by a sensor signal transmitted from a sensor; a vertical misalignment determining unit determining that vertical misalignment of the sensor occurs when the measured signal intensity of the surface reflected wave exceeds a reference signal intensity; and a vertical alignment adjusting unit automatically correcting the vertical misalignment of the sensor, in response to a determination by the vertical misalignment determining unit that vertical misalignment of the sensor occurs, by controlling a tilting motor, switching one of a plurality of transmitting antennas set to different radiating angles to one set to the radiating angle required to correct the vertical misalignment, or switching one of a plurality of receiving antennas set to different receiving angles to one set to the receiving angle required to correct the vertical misalignment.
