Abstract

A method for providing vehicle information includes: receiving first vehicle data encoded according to a first protocol and corresponding to an environment external to a vehicle; receiving high definition mapping data corresponding to objects in the environment external to the vehicle; generating position information for objects indicated in the high definition mapping data by correlating locations of objects indicated by the high definition mapping data with objects in the environment external to the vehicle detected by at least one sensor; generating second vehicle data by correlating the high definition mapping data, the position information, and the first vehicle data; and encoding the second vehicle data according to a second protocol.

First claim

We claim:

1 . A system for providing vehicle information, the system comprising:
a processor; and a memory including instructions that, when executed by the processor, cause the processor to: receive first vehicle data encoded according to a first protocol and corresponding to an environment external to a vehicle; receive high definition mapping data corresponding to objects in the environment external to the vehicle; generate position information for objects indicated in the high definition mapping data by correlating locations of objects indicated by the high definition mapping data with objects in the environment external to the vehicle detected by at least one sensor; generate second vehicle data by correlating the high definition mapping data, the position information, and the first vehicle data; and encode the second vehicle data according to a second protocol.

2 . The system of claim 1 , wherein the first protocol corresponds to advanced driver assistance systems interface specifications version 2 protocol.

3 . The system of claim 1 , wherein the second protocol corresponds to advanced driver assistance systems interface specifications version 3 protocol.

4 . The system of claim 1 , wherein the first vehicle data includes one or more of geometry data, speed limit data, lane data, road curvature data, and road slope data.

5 . The system of claim 1 , wherein the second vehicle data includes the first vehicle data and one or more of object lane level accuracy data, longitudinal position data, latitudinal position data, and lane boundary data.

6 . The system of claim 1 , wherein the first vehicle data includes standard definition mapping data.

7 . The system of claim 1 , wherein the at least one sensor includes an image capturing device.

8 . The system of claim 1 , wherein the at least one sensor includes one of a LIDAR device, a radar device, an ultrasonic device, and a fusion device.

9 . A method for providing vehicle information, the method comprising:
receiving first vehicle data encoded according to a first protocol and corresponding to an environment external to a vehicle; receiving high definition mapping data corresponding to objects in the environment external to the vehicle; generating position information for objects indicated in the high definition mapping data by correlating locations of objects indicated by the high definition mapping data with objects in the environment external to the vehicle detected by at least one sensor; generating second vehicle data by correlating the high definition mapping data, the position information, and the first vehicle data; and encoding the second vehicle data according to a second protocol.

10 . The method of claim 9 , wherein the first protocol corresponds to advanced driver assistance systems interface specifications version 2 protocol.

11 . The method of claim 9 , wherein the second protocol corresponds to advanced driver assistance systems interface specifications version 3 protocol.

12 . The method of claim 9 , wherein the first vehicle data includes one or more of geometry data, speed limit data, lane data, road curvature data, and road slope data.

13 . The method of claim 9 , wherein the second vehicle data includes the first vehicle data and one or more of object lane level accuracy data, longitudinal position data, latitudinal position data, and lane boundary data.

14 . The method of claim 9 , wherein the first vehicle data includes standard definition mapping data.

15 . The method of claim 9 , wherein the at least one sensor includes an image capturing device.

16 . The method of claim 9 , wherein the at least one sensor includes one of a LIDAR device, a radar device, an ultrasonic device, and a fusion device.

17 . An apparatus comprising:
a processor; and a memory including instructions that, when executed by the processor, cause the processor to:
receive standard defection vehicle data encoded according to a first protocol and corresponding to an environment external to a vehicle;
receive high definition mapping data corresponding to objects in the environment external to the vehicle;
generate position information for objects indicated in the high definition mapping data by correlating locations of objects indicated by the high definition mapping data with objects in the environment external to the vehicle detected by at least one sensor;
generate high definition vehicle data by correlating the high definition mapping data, the position information. and the first vehicle data;
determine a probable path for the vehicle using the high definition vehicle data; and
encode the probable path according to a second protocol.

18 . The apparatus of claim 17 , wherein the first protocol corresponds to advanced driver assistance systems interface specifications version 2 protocol.

19 . The apparatus of claim 17 , wherein the second protocol corresponds to advanced driver assistance systems interface specifications version 3 protocol.

20 . The apparatus of claim 17 , wherein the instructions further cause the processor to store the probable path in a database.
