Abstract
The disclosure includes embodiments for adaptive sensor data sharing by a connected vehicle. A method includes calculating, by a processor of an ego vehicle, a view angle overlap between a first sensor of the ego vehicle and a second sensor of a roadway device, wherein the view angle overlap is an amount of sensor view overlap shared by first sensor and the second sensor. The method includes determining an amount of ego sensor data to share with the roadway device based on the view angle overlap. The method includes building a sharing message that includes the amount of ego sensor data in a payload of the sharing message. The method includes transmitting, by a communication unit of the ego vehicle, the sharing message to the roadway device.
Claims20
A method executed by an ego vehicle, the method comprising:
- calculating, by a processor of the ego vehicle, a view angle overlap between a first sensor of the ego vehicle and a second sensor of a roadway device, wherein the view angle overlap is an amount of sensor view overlap shared by first sensor and the second sensor;
- determining an amount of ego sensor data to share with the roadway device based on the view angle overlap;
- building a sharing message that includes the amount of ego sensor data in a payload of the sharing message;
- and
- transmitting, by a communication unit of the ego vehicle, the sharing message to the roadway device.
A computer program product included in at least one onboard vehicle computer of an ego vehicle, the computer program product comprising computer code that is operable, when executed by the onboard vehicle computer, to cause the onboard vehicle computer to execute steps including:
- calculating, by the onboard vehicle computer, a view angle overlap between a first sensor of the ego vehicle and a second sensor of a roadway device, wherein the view angle overlap is an amount of sensor view overlap shared by first sensor and the second sensor;
- determining an amount of ego sensor data to share with the roadway device based on the view angle overlap;
- building a sharing message that includes the amount of ego sensor data in a payload of the sharing message;
- and
- transmitting, by a communication unit of the ego vehicle, the sharing message to the roadway device.
A system included in an ego vehicle, the system comprising:
- a processor;
- a communication unit;
- a non-transitory memory communicatively coupled to the processor and the communication unit, which are communicatively coupled to one another, wherein the non-transitory memory stores executable code that is operable, when executed by the processor, to cause the processor to:
- calculate, by the processor, a view angle overlap between a first sensor of the ego vehicle and a second sensor of a roadway device, wherein the view angle overlap is an amount of sensor view overlap shared by first sensor and the second sensor;
- determine an amount of ego sensor data to share with the roadway device based on the view angle overlap;
- build a sharing message that includes the amount of ego sensor data in a payload of the sharing message;
- and
- transmit, by the communication unit, the sharing message to the roadway device.
