A Study on Reliable Intelligent Vehicle Driving System by Using Features of Electric Vehicles

Intelligent vehicle systems, such as the automatic driving system are expected to be the solution of current traffic problems. The key of those systems is reliability. This paper investigates a possibility of improving reliability by using the features of an electric vehicle (EV). EV with two motors can generate traction forces independently at left and right wheels and can control yaw moment adequately when a steering system is broken. The turning performance is evaluated in respect to vehicle's velocity, difference of traction forces, and steering condition by simulations and experiments. It is clarified that the lane-keeping can be realized by traction-force-distribution control. A lane-keeping controller by distribution of traction forces is proposed and validated by simulations. The fruit of this study improves reliability of automatic driving and shows the EV's advantage towards future vehicle systems. (A)
