Vehicle on-board unit

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.
