In this paper, a model-based strategy is used to realize rapid searching of the shortest path in order to solve the global optimizing problem in the path planning of the mobile robot. The Hough transform is used to build the cell map of the working environment for the mobile robot by extracting the fringes information of the solid obstacles and map them into a 2D plane. We simplify the construction of the state space and design of the search strategy based on free cells' evaluation by the distance which is between the start point and the goal point. The relatively shortest path's search is realized through the state space of the cell map by path search tree. The experimental and simulation results show that the path search strategy doesn't need complicated computations. Furthermore it is effectiveness in completeness, time complexity, space complexity and optimality.

This paper presents a new method for detecting flaws in vehicular wheel based on anti-geometric diffusion. The classical image-processing methods for flaw detection can not produce a result with satisfaction, because the shape of the flaw can't be outlined exactly and these methods usually can do nothing about the flaw image with unhomogeneous lighting background. A new two-step technique is proposed in the paper. First, we use an anisotropic diffusion model to the flaw image with noise, this step can eliminate the noise and keep the shape of the flaws. Second, we use anti-geometric diffusion to the image, which is the result of first step, this step can track the flaws very accurately though unhomogeneous lighting background may be exist in the flaw image. Using this method, the flaws can be detected with high certainty. Our experiments also give the good results based on this new method.

Vehicle stability control for a 4WD hybrid electric vehicle is investigated using the rear motor driving/regenerative braking control and electro-hydraulic brake (EHB) control. A fuzzy rule based control algorithm is proposed, which generates the direct yaw moment to compensate the errors of the sideslip angle and yaw rate. Performance of the vehicle stability control algorithm is evaluated using ADAMS/Car and MATLAB Simulink co-simulation. The co-simulation program consists of 3 parts (1) ADAMS/Car model, (2)MATLAB Simulink model and (3) interface model. It is found from the simulation results that the direct yaw moment generated by the rear motor control is able to provide the improved stability compared with the vehicle performance without any control. It is found that better performance can be achieved by applying the rear motor plus EHB control.

The precise calculation of front wheel toe-in of vehicles is the base of the control for toe-in tracing camber and simulation of vehicles' handling and stability. Since the match between the toe-in and camber depends on several factors, it is difficult to give a precise calculation of the toe-in according to a given camber. A semi-empirical approach is developed based on theoretical analysis combined with measurement techniques. As an application, the developed approach is used to determine the optimistic front wheel toe-in of a domestic 1026 model pick-up vehicle. Based on the sideslip test of the vehicle, the formulation of the sideslip value and toe-in is determined by regress analysis. By comparing the theoretical and the regressed toe-in corresponding to the minimum sideslip value, the theoretical formulation is modified to suit for the pick-up vehicle considered. The proposed methodology provides a precise mathematical model for the control of toe-in tracing camber, which might be used to improve the high speed safety of vehicles.

Human-computer interaction for in-vehicle information and navigation systems is a challenging problem. In this paper, we propose a robust system for speaker localization and speech enhancement for an in-vehicle speech dialog system by using microphone arrays. The performance of traditional localization methods drastically decline in a moderately reverberant environment. In this paper, we introduce Gauss-Hermite filter to integrate the current observation, effectively steer particles towards regions with high likelihood. The sound source localization (SSL) method based on the model of the precedence effect is integrated into the framework of speaker localization based on particle filters. The simulation indicates that the proposed algorithm is able to accurately track speaker in a moderately reverberant car environment.

In this study, vehicle stability control system is studied by using linear two degrees of freedom vehicle model. Vehicle stability control strategy is based on the direct yaw moment control that adopts the fuzzy PI controller. Compared with conventional PI control, the fuzzy PI control can regulate the proportional and integral parameters and improve the responds of system. The direct yaw moment is distributed to the desired controlled wheel as target braking pressure through differential braking strategy. Various computer simulation results show the vehicle stability control system using fuzzy PI control can improve the handling and stability of vehicle on low friction road significantly.

In this paper, a transient dynamic model is proposed for the hybrid electric vehicle (HEV) engine for the purpose of alleviation of high frequency oscillations in engine revolutions, which is extended to develop a digital governor providing a high fidelity estimation of rotary speed oscillation for hybrid vehicle engines. To damp speed oscillation, a hybrid fuzzy-PID controller is implemented for HEV engine speed regulation. By comparison between measured and estimated signals, it is demonstrated that a good agreement has been achieves and the governor behaves an excellent damping speed ripple.
