Abstract
The inventive subject matter is directed to implementing the fusion of road geometry model information in different forms from different sources in a manner that is comprehensive, efficient, and effective. Such fused road geometry model information for a particular vehicle (i.e., an ego vehicle) provides for improved performance of active safety functionality. Examples of active safety functionalities include, but are not limited to, curve speed warning, selection of target objects that are potential threats to the ego vehicle by helping the ego vehicle's path prediction, and the like.
Claims25
A method, comprising:
- receiving road geometry model information generated by each one of a plurality of road geometry model information sources of a vehicle, wherein the road geometry model information of each one of the road geometry model information sources characterizes a geometry of an approaching segment of a roadway over which the vehicle is traveling;
- and
- creating a synthetic road geometry model dependent upon the road geometry model information of a first one of the road geometry model information sources and the road geometry model information of a second one of the road geometry model information sources in response to determining that the road geometry model information of the first one of the road geometry model information sources and the road geometry model information of the second one of the road geometry model information sources each suitably approximate the geometry of the approaching segment of the roadway.
A vehicle, comprising:
- a plurality of road geometry model information sources each generating respective road geometry model information defining a respective road geometry model characterizing a geometry of an approaching segment of a roadway over which the vehicle is traveling;
- and
- a road geometry model fusing module coupled to each one of the road geometry model information sources, wherein the road geometry model fusing module compares a first road geometry model generated by a first one of the a first one of the road geometry model information sources to a second road geometry model generated by a second one of the road geometry model information sources and, in response to determining that the first road geometry model and the second road geometry model each suitably approximate the geometry of the approaching segment of the roadway, creates a synthetic road geometry model dependent upon the first road geometry model and the second road geometry model.
A processor-readable medium having tangibly embodied thereon and accessible therefrom a set of instructions interpretable by at least one data processing device, the processor-readable medium being non-transient, the set of instructions configured for causing the at least one data processing device to carry out operations for:
- receiving road geometry model information generated by each one of a plurality of road geometry model information sources of a vehicle, wherein the road geometry model information of each one of the road geometry model information sources characterizes a geometry of an approaching segment of a roadway over which the vehicle is traveling;
- and
- creating a synthetic road geometry model dependent upon the road geometry model information of a first one of the road geometry model information sources and the road geometry model information of a second one of the road geometry model information sources in response to determining that the road geometry model information of the first one of the road geometry model information sources and the road geometry model information of the second one of the road geometry model information sources each suitably approximate the geometry of the approaching segment of the roadway.
