Abstract
A system and method includes, among other things, providing at least three vehicle transceivers, communicating with each vehicle transceiver via a remote device, and estimating a distance to the remote device for each vehicle transceiver. Estimated distances from the at least three vehicle transceivers and trilateration are used to determine an actual distance of the remote device from the vehicle.
Claims20
A method comprising:
- providing at least three vehicle transceivers;
- communicating with each vehicle transceiver via a remote device;
- estimating a distance to the remote device for each vehicle transceiver;
- and
- using estimated distances from the at least three vehicle transceivers and trilateration to determine an actual distance of the remote device from the vehicle.
2 more elements
A method comprising:
- providing at least a first vehicle transceiver, a second vehicle transceiver, and a third vehicle transceiver;
- communicating with the first, second, and third vehicle transceivers via a remote device;
- estimating a first distance from the first vehicle transceiver to the remote device;
- estimating a second distance from the second vehicle transceiver to the remote device;
- estimating a third distance from the third vehicle transceiver to the remote device;
- and
- using the first, second, and third estimated distances to determine an actual distance of the remote device from the vehicle via trilateration.
4 more elements
A system comprising:
- at least three vehicle transceivers in communication with a remote device, wherein an estimated distance to the remote device is determined for each of the at least three vehicle transceivers;
- and
- a control unit configured to use trilateration and the estimated distances to determine an actual distance of the remote device from the vehicle.
