Abstract
Provided are a UWB-based method and apparatus for positioning a vehicle. The method includes: receiving, by the UWB module, UWB signals sent by UWB anchors on the vehicle, and acquiring a first relative distance parameter between the intelligent key and the vehicle based on the UWB signals; determining, when the first relative distance parameter is within a first preset distance range, direction information of the vehicle based on the UWB signals; determining, when the first relative distance parameter is within a second preset distance range, relative position information between the intelligent key and the vehicle based on the UWB signals; and outputting vehicle guidance information based on the direction information of the vehicle or the relative position information. A maximum distance parameter in the second preset distance range is less than a minimum distance parameter in the first preset distance range.
