Abstract

A method of a vehicle obtaining sensor data originating at one or more of other vehicles includes receiving input from an operator or system within the vehicle, and generating a request for the sensor data based on the input. The request specifies one or more parameters and the one or more parameters include a location at which the sensor data is obtained. The method also includes sending the request for the sensor data, receiving the sensor data, and processing the sensor data. The processing includes providing the sensor data to the operator or the system within the vehicle based on the input. A central server includes an interface to receive sensor data and parameters from one or more vehicles according to vehicle-to-network (V2N) communication. A processor generates a digital map from the sensor data. The digital map includes a layer for each type of the sensor data.

Claims

1. A method of a vehicle obtaining sensor data originating at one or more other vehicles, the method comprising:

receiving input from an operator or system within the vehicle;

generating a request for the sensor data based on the input, wherein the request specifies one or more parameters and the one or more parameters include a location at which the sensor data is obtained using one or more sensors at the one or more other vehicles;

sending the request for the sensor data;

receiving the sensor data; and

processing the sensor data, wherein the processing the sensor data includes providing the sensor data to the operator or the system within the vehicle based on the input.

2. The method according to claim 1, wherein the sending the request for the sensor data includes broadcasting the request via vehicle-to-vehicle (V2V) communication to the one or more other vehicles.

3. The method according to claim 2, further comprising the vehicle receiving an acknowledgment from the one or more other vehicles, each acknowledgment including quality information.

4. The method according to claim 3, further comprising the vehicle selecting the one or more vehicles such that the receiving the sensor data is received from the one or more vehicles.

5. The method according to claim 1, wherein the sending the request for the sensor data includes sending the request to a central server that obtains the sensor data from the one or more other vehicles.

6. A system in a vehicle to obtain sensor data originating at other vehicles, the system comprising:

an interface configured to receive an input from an operator or system within the vehicle requesting the sensor data, receive sensor data based on a request for the sensor data, and provide the sensor data to the operator or the system; and

a processor configured to generate the request for the sensor data based on the input, wherein the request specifies one or more parameters and the one or more parameters include a location at which the sensor data is obtained and the sensor data is obtained using one or more sensors at the other vehicles.

7. The system according to claim 6, wherein the interface outputs a broadcast of the request to the other vehicles via vehicle-to-vehicle (V2V) communication.

8. The system according to claim 7, wherein the vehicle receives an acknowledgement from one or more of the other vehicles, each acknowledgement indicating quality information.

9. The system according to claim 8, wherein the processor selects one or more of the one or more of the other vehicles based on the quality information and receives the sensor data from the one or more of the one or more of the other vehicles.

10. The system according to claim 6, wherein the interface sends the request for the sensor data to a central server that obtains the sensor data from the other vehicles.

11. A central server, comprising:

an interface configured to receive sensor data and one or more associated parameters from one or more vehicles according to vehicle-to-network (V2N) communication, wherein the one or more associated parameters include a time stamp and location;

a processor configured to generate a digital map from the sensor data, the digital map including a layer for each type of the sensor data, wherein one of the layers type of the sensor data includes camera images.

12. The central server according to claim 11, wherein the interface outputs a multicast of the digital map.

13. The central server according to claim 11, wherein the interface receives a request from a requesting vehicle, the request including a location of interest.

14. The central server according to claim 13, wherein the processor determines most relevant information based on the request and the digital map and sends the most relevant information to the requesting vehicle.

15. The central server according to claim 14, wherein the processor determines the most relevant information based on the one or more associated parameters.
