Antenna validation for vehicle-to-vehicle communication
First Claim
Patent Images
1. A vehicle comprising:
- a wireless communication module; and
an antenna calibrator to, for each of a plurality of validation responses received from second vehicles;
determine an estimated received signal strength based on an estimated open path signal strength loss; and
in response to a difference between the estimated received signal strength and an actual received signal strength from the validation response not satisfying a threshold, provide an alert to occupants of the vehicle.

Abstract
Systems, methods and apparatus are disclosed for antenna validation for vehicle-to-vehicle communication. An example disclosed vehicle includes a wireless communication module and an antenna calibrator. The example antenna calibrator, for each of a plurality of validation responses received from second vehicles (a) determines an estimated received signal strength based on an estimated open path signal strength loss, and (b) in response to a difference between the estimated received signal strength and an actual received signal strength from the validation response not satisfying a threshold, provides an alert to occupants of the vehicle.

8. A method to test an antenna of a vehicle-to-vehicle communication module, comprising:
-
receiving a validation response from a plurality of vehicles; for each of the validation responses, determining, with a processor, an estimated received signal strength based on an estimated open path signal strength loss; and in response to a difference between the estimated received signal strength and an actual received signal strength from one of the validation responses not satisfying a threshold, providing an alert to occupants of the vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a plurality of first vehicles, each one of the plurality of first vehicles to, in response to receiving a validation request message, broadcast a validation response message including first coordinates and a received signal strength value of the validation request message; and a second vehicle to; from time to time, determine second coordinates of the second vehicle and send the validation request message; and for each of the received validation responses messages, determine an indication of operational status of an antenna of the second vehicle based on the second coordinates, the first coordinates, and the received signal strength value. - View Dependent Claims (16, 17, 18, 19)
