Position Matching Based Autonomous Speed Regulation System for Vehicles

A novel approach for creating an advisory/regulatory environment to limit the maximum running speed of the vehicle is presented. This paper deals with creating an onboard speed regulation module for vehicles which can monitor as well as control their instantaneous speed in comparison with the maximum permissible speed of that location. The location is obtained using position tracking technology of GPS and GSM system. The work discusses the unique position matching algorithm developed and design details of the proposed on-board module for limiting vehicle's speed. The algorithm continuously compares the actual speed of the vehicle with its corresponding location based limits obtained through the developed database and thus provides: (a) An advisory signal to the driver about the need for a reduction in speed. (b) An automatic restriction of the speed below the prescribed limits.The algorithm matches the position with the geographical zone already defined in the database and compares the actual speed with the limit of the corresponding zone on an intermittent basis, depending on the execution time of the processing cycle. The algorithm developed tracks the vehicle position using data acquired from both GPS and GSM receivers which lead to increased efficiency, reduced complexity and processing time in contrast to the conventional methods.
