Method of dynamic intersection mapping
First Claim
1. A method of operating a collision warning system in a motor vehicle comprising:
- mapping a road section proximate the motor vehicle including;
receiving vehicle travel history information for the road section from a transmitter proximate the road section;
evaluating potential paths for the road section based on the vehicle travel history information;
wherein the road section includes an intersection between a first road and a second road; and
wherein the step of evaluating potential paths for the road section further includes estimating a lane configuration on the first road as it exits the intersection using the received vehicle travel history information for the road section;
determining a first path for the motor vehicle to traverse the road section including at least one lane associated with the estimated lane configuration for the intersection;
receiving a signal transmitted by a target vehicle;
determining a second path for the target vehicle to traverse the road section including at least one lane associated with the estimated lane configuration for the intersection; and
calculating a threat of collision for the motor vehicle with the target vehicle including comparing the first and second paths.

Abstract
A motor vehicle is provided having a collision warning system that can map an upcoming road section for the motor vehicle. The system can evaluate potential paths for the road section based on vehicle travel history information through it. The system can receive the information from a transmitter proximate the road section, such as a roadside transmitter or one or more nearby vehicles having traversed the road section. The road section can include an intersection and the system can determine a lane configuration for at least a portion of it based on vehicle travel history information. The system can calculate a threat of collision for the motor vehicle with a target vehicle based on map data obtained from estimated paths or lane configurations for the road section. Methods pertaining to mapping a road section and operation of the system are also provided.

17. A motor vehicle comprising:
-
a transmitter configured to transmit signals on a vehicle communications network; a receiver configured to receive signals on a vehicle communications network; a navigation system; and a collision warning system configured to perform actions comprising; mapping an upcoming road section identified by the navigation system, the mapping including; receiving via the receiver vehicle travel history information for the road section from a transmitter proximate the road section; evaluating potential paths for the road section based on the vehicle travel history information; wherein the road section includes an intersection between a first road and a second road; and wherein evaluating potential paths for the road section further includes estimating a lane configuration on the first road as it exits the intersection using the received vehicle travel history information for the road section; determining a first path for the motor vehicle to traverse the road section including at least one lane associated with the estimated lane configuration for the intersection; receiving via the receiver a signal transmitted by a target vehicle; determining a second path for the target vehicle to traverse the road section including at least one lane associated with the estimated lane configuration for the intersection; and calculating a threat of collision for the motor vehicle with the target vehicle including comparing the first and second paths. - View Dependent Claims (18, 19)

20. A method of operating a collision warning system in a motor vehicle, comprising:
-
dynamically mapping an upcoming road section for the motor vehicle traveling along a second road, the upcoming road section including an intersection of the second road with a first road, dynamically mapping the upcoming road section including; receiving first vehicle travel history information for the road section from a first supplemental vehicle having recently traversed the intersection along the first road; receiving second vehicle travel history information for the road section from a second supplemental vehicle having recently traversed the intersection along the first road; and estimating a lane configuration for the first road as it exits the intersection based on the received first and second vehicle travel history information; receiving a signal transmitted by a target vehicle; determining at least one lane associated with the estimated lane configuration for the intersection being traversed by the target vehicle based on the received signal transmitted by the target vehicle; and calculating a threat of collision for the motor vehicle with the target vehicle based on the estimated lane configuration and the at least one lane being traversed by the target vehicle.
