The Lateral Position Estimation System for Autonomous Driving of the Online Electric Vehicle

The electric vehicle technologies such as developing pure, hybrid electric vehicle, automated electric vehicle have been developed since early 1900s. These tries have not succussed well, however, because the cost and signal processing problem of the sensor and cost, re-charing time and weight of battery problems. Hence to solve these problem at the same time, we suggest the lateral position estimation system for autonomous driving of the OLEV based on power supply line. Since it is important to increase the efficiency of the wireless power transfer in online electric vehicle system on driving, we suggest a lateral position estimation system for autonomous driving of the OLEV. This paper considers three parts: 1) Introducing the OLEV system that is new concept of the electric vehicle that is supplied the power from the road on driving. 2) Sensing electric magnetic field on the Power supplied line that is installed under the road to supply power to the electric vehicle wirelessly. 3) Position estimation algorithm for finding the maximum wireless power transfer position on the road and for moving the OLEV automatically on the power supplied line.
