Kind Code:
A1
Abstract:
This obstacle detection device (100) comprises a range measurement unit (22) for grouping direct waves (DW) and indirect waves (IW) transmitted and received by a distance sensor (2) and calculating the ranges (R) between the rising times (T_up_first) and falling times (T_down_last) of the reception signals (RS) of the groups (G), an averaging processing unit (23) for calculating an average range (R_ave) by averaging the ranges (R), and a height determination unit (24) for determining the height of an obstacle (O) by comparing the average range (R_ave) with a threshold (Th).
