An experimental system for processing movement information of vehicle

This paper presents a proposed experimental system for processing movement information of vehicle. Using self-contained on-line computing processor which computes position and heading angle (azimuth), trajectory of location of vehicle has been successfully displayed by an experimental system implemented. Principles of self-contained computing system are as follows: accurate digital moving pick-ups are set on both sides of vehicle wheels, accumulation of both sides data which are picked periodically is for distance measuring and subtraction of both sides data is for heading computation, self-contained processor computes the location and heading angle, and also presents location data on X-Y recorder and digital displays. Coordinate location and heading computations are performed by electronic hard-ware mechanization. Methods for reduction of induced errors are discussed and experimentally demonstrated.
