Method and apparatus for positioning a vehicle based on uwb

An apparatus for positioning a vehicle based on an ultra-wideband (UWB), applied in an intelligent key including a UWB module, the apparatus comprising:

• an acquisition module configured to receive, based on the UWB module, UWB signals sent by UWB anchors configured on the vehicle, and acquire, based on the UWB signals, a first relative distance parameter between the intelligent key and the vehicle;
• a first determination module configured to determine, when the first relative distance parameter is within a first preset distance range, direction information of the vehicle based on the UWB signals sent by the UWB anchors;
• a second determination module configured to determine, 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 sent by the UWB anchors, wherein a maximum distance parameter in the second preset distance range is less than a minimum distance parameter in the first preset distance range;
• and
• an output module configured to output vehicle guidance information based on the direction information or the relative position information of the vehicle.
