VEHICLE ON-BOARD UNIT
First Claim
1. A vehicle on-board unit comprising:
- a communication system; and
a controller includinga vehicle path history generating component configured to generate a host vehicle path history data indicative of a travel path of a host vehicle in a lane in which the host vehicle is currently traveling, with the lane being a single lane of a road, the road having one or more lanes,a lane centerline determining component configured to receive a preceding vehicle message including at least a preceding vehicle centerline data from the communication system and determine a host vehicle lane centerline data indicative of a centerline of the lane based on the host vehicle path history data and the preceding vehicle centerline data, anda message processing component configured to produce a host vehicle message including at least the host vehicle lane centerline data, with the communication system being configured to broadcast the host vehicle message.

Abstract
A vehicle on-board unit communicates with vehicles to increase the accuracy of lane centerline determination. The on-board unit includes a communication system and a controller. The controller has a vehicle path history generating component, a lane centerline determining component, and a message processing component. The vehicle path history generating section generates a host vehicle path history data. The lane centerline determining section receives a preceding vehicle message including at least a preceding vehicle centerline data from the communication system and determines a host vehicle lane centerline data indicative of a centerline of the lane based on the host vehicle path history data and the preceding vehicle centerline data. The message processing component produces a host vehicle message including the host vehicle lane centerline data, the communication system being configured to broadcast the host vehicle message.

11. A lane centerline determination method comprising:
-
generating a host vehicle path history data indicative of a travel path of a host vehicle in a lane in which the host vehicle is currently traveling, with the generating of the host vehicle path history data being accomplished using a vehicle on-board unit of the host vehicle, and with the lane being a single lane of a road, the road having one or more lanes; determining a host vehicle lane centerline data indicative of a centerline of the lane based on the host vehicle path history data and a preceding vehicle centerline data; producing a host vehicle message including at least the host vehicle lane centerline data; and broadcasting the host vehicle message. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
