Abstract
Techniques for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle can include monitoring the primary mode of RF communication to ensure it is effectively communicating and, if not, intelligently selecting a backup communication mode comprising one or more other sensors and/or systems of the vehicle. The selection of the backup communication mode may take into account various factors that can affect the various modes of communication from which the backup communication mode is selected.
Claims30
A method of determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle, the method comprising:
- monitoring signals of a primary radio frequency (RF) communication mode used by the host vehicle for vehicle-to-vehicle communication;
- determining, based at least in part on the monitoring, that a density of vehicles has exceeded a threshold density value;
- responsive to the determining that the density of vehicles has exceeded the threshold density value, selecting, from one or more alternative communication modes alternative to the primary RF communication mode, a second RF communication mode with which to send a vehicle-to-vehicle message;
- and
- sending, from the host vehicle, the vehicle-to-vehicle message via the second RF communication mode.
A device for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle, the device comprising:
- a first transceiver configured to be used in a primary radio frequency (RF) communication mode by the host vehicle for vehicle-to-vehicle communication;
- a second transceiver configured to be used in one or more alternative communication modes alternative to the primary RF communication mode;
- a memory;
- and
- a processing unit communicatively coupled with the first transceiver, the second transceiver, and the memory, wherein the processing unit is configured to:
- monitor signals of the primary RF communication mode used by the host vehicle for vehicle-to-vehicle communication;
- determine, based at least in part on the monitoring, that a density of vehicles has exceeded a threshold density value;
- responsive to the determining that the density of vehicles has exceeded the threshold density value, select, from one or more alternative communication modes alternative to the primary RF communication mode, a second RF communication mode with which to send a vehicle-to-vehicle message;
- and
- send, from the host vehicle, the vehicle-to-vehicle message via the second RF communication mode using the second transceiver.
An apparatus for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle, the apparatus comprising:
- means for monitoring signals of a primary radio frequency (RF) communication mode used by the host vehicle for vehicle-to-vehicle communication;
- means for determining, based at least in part on the monitoring, that a density of vehicles has exceeded a threshold density value;
- means for, responsive to the determining that the density of vehicles has exceeded the threshold density value, selecting, from one or more alternative communication modes alternative to the primary RF communication mode, a second RF communication mode with which to send a vehicle-to-vehicle message;
- and
- means for sending, from the host vehicle, the vehicle-to-vehicle message via the second RF communication mode.
A non-transitory computer-readable medium storing instructions for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle, the instructions comprising code for:
- monitoring signals of the primary RF communication mode used by the host vehicle for vehicle-to-vehicle communication;
- determining, based at least in part on the monitoring, that a density of vehicles has exceeded a threshold density value;
- responsive to the determining that the density of vehicles has exceeded the threshold density value, selecting, from one or more alternative communication modes alternative to the primary RF communication mode, a second RF communication mode with which to send a vehicle-to-vehicle message;
- and
- sending, from the host vehicle, the vehicle-to-vehicle message via the second RF communication mode.
