Algorithm of optimal space selection for lane change is proposed for helping drivers to find the optimal Lane Change Feasible Space (LCFS). This paper provides the TSK fuzzy logic algorithm for selection. This algorithm is verified by simulation results through Matlab /Simulink and Carsim(version 8.1a)

This paper proposes an analytical redundancy technique for fault diagnostics of the sensor in steer-by-wire system. We use incorporating vehicle dynamics modeling into the design of a diagnostic system for steer-by-wire system. The use of a model of vehicle dynamics improves the speed and accuracy of the diagnoses. The proposed fault diagnostics algorithm is based on parity-space methods to generate residuals. To reduce the effects of modeling uncertainty and dynamic transients, the residuals are subject to filtering. We construct diagnostic system consisting residual threshold for detection and isolator with using the directional residual vector.

In current ITS(Intelligent Transportation System), most route guidance services use cellularphone, PDA and navigation kit. Since these systems are depend on unilateral telecommunication, they guide almost drivers with same route. And it may cause traffic jam. Therefore, telecommunication system which can telecommunicate between vehicle and base station bilaterally and algorithm which is able to divide traffic flow are necessary to realize the efficient route guidance system.<br/> This paper introduces bilateral telecommunication system and proposes indexes such as 'Driving capability' and 'Route difficulty' to improve the performance of route guidance system. We can divide traffic flow by setting up the initial route individually based on driving capability and route difficulty in this system. If there is a traffic jam in the initial route, we can modify the route in local area temporarily by route modification algorithm. Therefore, we can realize the efficient route guidance system using above methods. The simulation results presented in this paper verify the proposed method.
