Title:
OVERPASS IDENTIFICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/010923
Kind Code:
A1
Abstract:
Provided are an overpass identification method and apparatus. The method comprises: determining a first parameter at a first moment according to a GNSS signal (S11); determining a second parameter of a vehicle (100) at a first moment by means of a sensor (S12); determining the driving state of the vehicle (100) by combining the first parameter with the second parameter (S13); and when the driving state of the vehicle (100) is a target state, then determining an overpass identification result of the vehicle (100) according to the height change of the vehicle (100) (S14). The target state comprises at least one among the following driving states: starting to join a ramp, ending joining the ramp, starting to leave the ramp and ending leaving the ramp. The overpass identification result of the vehicle (100) is that the vehicle (100) is driving on a road on the upper side of an overpass or that the vehicle (100) is driving on a road on the lower side of the overpass. Thus, the problem that the overpass identification result of the vehicle (100) cannot be determined may be solved, the number of navigation error instances is further reduced, and navigation accuracy is improved.
