Systems and methods for ultra wideband-based lift and tire deflation detection in vehicles

A vehicle comprising:

• a controller;
• one or more ultra-wideband (UWB) radar units coupled to the controller;
• and
• a memory device coupled to the controller and including instructions, that when executed by the controller cause the controller to:
• determine that a set of preconditions are satisfied;
• determine, at a first time and in response to the set of preconditions being satisfied, a first distance between a first UWB radar unit, of the one or more UWB radar units, and a reference surface on which the vehicle is resting;
• determine, at a second time after the first time and in response to the set of preconditions being satisfied, a second distance between the first UWB radar unit and the reference surface;
• determine based on the second distance, that the second distance is higher than a threshold;
• determine, based on the second distance being higher than the threshold, that the vehicle is positioned vertically above the reference surface;
• and
• generate a notification indicating occurrence of an unauthorized activity associated with the vehicle.

A method comprising:

• determining, by a controller of a vehicle, that a set of preconditions are satisfied, wherein the set of preconditions include a vehicle ignition of the vehicle being in an off state, all doors of the vehicle being in a closed state, all the doors of the vehicle being in a locked state, and a user device associated with the vehicle being more than a threshold distance away from the vehicle;
• determining, by the controller at a first time, first data from an ultra-wideband (UWB) radar unit of the vehicle, the first data indicative of a first distance between the UWB radar unit and a reference surface on which the vehicle is resting;
• determining, by the controller at a second time after the first time, second data from the UWB radar unit, the second data indicative of a second distance between the UWB radar unit and the reference surface;
• determining, by the controller, that the second distance is less than the first distance;
• and
• determining, by the controller based on the second distance being less than the first distance, that one or more tires of the vehicle are in a deflated state.
