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.
Claims18
A communication module for a vehicle comprising:
- an antenna;
- and
- a processor communicatively coupled to memory, the processor to:
- receive, via the antenna, validation responses from each a plurality of remote communication modules, the validation response to include coordinates and an actual received signal strength and the remote communication modules including at least one second vehicle and at least one roadside unit;
- for each of the validation responses, determine a delta signal loss between (a) an estimated received signal strength based on an estimated open path signal strength loss and the coordinates and (b) the actual received signal strength;
- and
- provide an alert to occupants of the vehicle when multiple of the delta signal losses do not satisfy a threshold.
A non-transitory computer readable medium comprising instructions that, when executed cause a communication module of a vehicle to:
- receive, via an omni-directional antenna, validation responses from each a plurality of remote communication modules, the validation response to include coordinates and an actual received signal strength and the remote communication modules including at least one second vehicle and at least one roadside unit;
- for each of the validation responses, determine a delta signal loss between (a) an estimated received signal strength based on an estimated open path signal strength loss and the coordinates and (b) the actual received signal strength;
- and
- provide an alert to occupants of the vehicle when multiple of the delta signal losses do not satisfy a threshold.
