Abstract
Official abstract text for this publication.
A mounting angle detection system of a Blind Spot Detection (BSD) sensor includes: the BSD sensor that is mounted at a predetermined location of a vehicle so as to detect a peripheral object; a displacement sensor that is fixedly disposed outside of the vehicle so as to detect a location of the vehicle; a Doppler generator that generates a radio wave of a wavelength in which the BSD sensor can detect; a moving unit that moves the Doppler generator to a detection area in which the BSD sensor can detect; and a control unit that calculates a deviation between a detection location and a reference location of the vehicle and that controls the moving unit so as to correct a location of the Doppler generator according to the deviation.
First claim
Opening claim text (preview).
What is claimed is: 1 . A mounting angle detection system of a Blind Spot Detection (BSD) sensor, the mounting angle detection system comprising: the BSD sensor that is mounted at a predetermined location of a vehicle so as to detect a peripheral object; a displacement sensor that is disposed outside of the vehicle so as to detect a location of the vehicle; a Doppler generator configured to generate a radio wave of a wavelength in which the BSD sensor can detect; a moving unit that moves the Doppler generator to a detection area in which the BSD sensor can detect; and a control unit that calculates a deviation between an actual location and a reference location of the vehicle and that controls the moving unit so as to correct a location of the Doppler generator according to the deviation. 2 . The mounting angle detection system of claim 1 , wherein the control unit calculates a mounting angle deviation of the BSD sensor from a radio wave central axis of the radio wave that is generated in the Doppler generator and a measurement reference axis of the BSD sensor. 3 . The mounting angle detection system of claim 2 , wherein the control unit compares the mounting angle deviation and a predetermined value of the BSD sensor, generates a fail signal, if the mounting angle deviation exceeds the predetermined value, and generates a pass signal, if the mounting angle deviation is the predetermined value or less. 4 . The mounting angle detection system of claim 1 , wherein the BSD sensor is disposed at both sides of a rear side of the vehicle. 5 . The mounting angle detection system of claim 1 , wherein the moving unit is a multi-axis robot. 6 . The mounting angle detection system of claim 1 , wherein the displacement sensor detects a location of the vehicle using radar. 7 . A method of detecting a mounting angle of a Blind Spot Detection (BSD) sensor, the method comprising the steps of: detecting an actual location of a stopped vehicle through a displacement sensor; calculating a deviation between the actual location and a reference location; and correcting a location of a Doppler generator that is detected by the BSD sensor according to the deviation. 8 . The method of claim 7 , further comprising the step of: calculating a mounting angle deviation of the BSD sensor from a radio wave central axis of a radio wave that is generated in the Doppler generator and a measurement reference axis of the BSD sensor. 9 . The method of claim 7 , further comprising the steps of: comparing a mounting angle deviation and a predetermined value of the BSD sensor; generating, if the mounting angle deviation exceeds the predetermined value, a fail signal; and generating, if the mounting angle deviation is the predetermined value or less, a pass signal.
