Abstract
A system and method are provided for determining a location of a portable device relative to an object. The system and method may include operating in two modes: 1) a first mode in which an antenna output, such as a received signal strength indicator, satisfies a mode transition criterion that is dynamic, and 2) a second mode in which, with the mode transition criterion being satisfied, the location of the portable device is determined.
Claims21
(canceled)
A method comprising:
- obtaining, by a vehicle, ranging-related measurements associated with the vehicle;
- generating, by the vehicle, a calibration parameter based on at least a portion of the ranging-related measurements;
- obtaining additional ranging-related measurements associated with the vehicle;
- and
- determining a distance between a mobile device and the vehicle based on the additional ranging-related measurements and the calibration parameter,
- wherein generating the calibration parameter is performed based on ranging-related measurements that are obtained separately from the additional ranging-related measurements used to determine the distance.
3 more elements
A method comprising:
- obtaining, by a vehicle, ultra-wideband (UWB) ranging-related measurements associated with one or more vehicle-side wireless sensors;
- generating, by the vehicle, a calibration parameter based on at least a portion of the UWB ranging-related measurements;
- storing the calibration parameter;
- and
- determining a distance between the vehicle and a mobile device based on distance-related measurements and the calibration parameter,
- wherein generating the calibration parameter is performed based on UWB ranging-related measurements that are obtained separately from the distance-related measurements used to determine the distance.
3 more elements
A system comprising:
- one or more vehicle-side wireless sensors configured to obtain ultra-wideband (UWB) ranging-related measurements;
- and
- a controller for a vehicle and configured to:
- generate a calibration parameter based on at least a portion of the UWB ranging-related measurements;
- store the calibration parameter;
- and
- determine a distance between the vehicle and a mobile device based on distance-related measurements and the calibration parameter,
- wherein the controller is configured to generate the calibration parameter based on UWB ranging-related measurements that are obtained separately from the distance-related measurements used to determine the distance.
