TLDR
A Kalman filter has been developed to integrate the three positioning systems (differential odometer dead reckoning, map matching, and GPS) used in the Automatic Vehicle Location System (AVL 2000) being designed and developed in the Department of Surveying Engineering at the University of Calgary as mentioned in this paper.Abstract:
A Kalman filter has been developed to integrate the three positioning systems (differential odometer dead reckoning, map matching, and Global Positioning System or GPS) used in the Automatic Vehicle Location System (AVL 2000) being designed and developed in the Department of Surveying Engineering at the University of Calgary The system is being targeted for on road applications and incorporates a digital map The filter has been designed to take into account uncertainties via covariance matrices In wide-open spaces GPS positioning will dominate, while in zones where the GPS signal is obstructed, dead reckoning will be used as interpolation between GPS position fixes Simulation studies and covariance analyses have been performed on a test route located in a sector of the city of Calgary >read more

GPS vehicle collision avoidance warning and control system and method
TL;DR: In this article, an automotive auto-pilot mode is provided, which generates control signals which actuate a plurality of control systems of the one vehicle in a coordinated manner to maneuver it laterally and longitudinally to avoid each collision hazard, or, for motor vehicles, when a collision is unavoidable, to minimize injury or damage therefrom.

Vehicular Ad Hoc Networks: A New Challenge for Localization-Based Systems
TL;DR: This paper surveys each of the localization techniques that can be used to localize vehicles and examines how these localization techniques can be combined using Data Fusion techniques to provide the robust localization system required by most critical safety applications in VANets.
Matching gps observations to locations on a digital map
TL;DR: A topologically based matching procedure that was tested with low quality GPS data and the performance of the algorithms was found to produce outstanding results.

A Novel Approach to Automotive Navigation and Map Display
Stanley K. Honey,Walter B Zavoli +1 more
TL;DR: In this article, a novel approach to automatic navigation and map display is described, and a navigation and display system for cars is presented. But, in order for a navigation system to be both cost effective and useful in automobiles, solutions are needed to problems in navigation, map database, data storage, and display.

Satellite Navigation Systems for Land Vehicles
TL;DR: In this paper, the authors integrated an experimental GPS receiver into a GM Buick Park Avenue, which was designed to acquire and sequentially track signals from four satellites, and presented the vehicle's precise latitude, longitude, and altitude on a color cathode ray tube (CRT) map display in the car's instrument panel.
