The purpose of UTMS's emergency call system is to help speedy rescue operation for traffic accidents. The cellular phone is a rapid and effective method to report an emergency but is difficult in determining the accident location. To solve this issue, this emergency call system plans to incorporate onboard equipment with a position detection function (such as GPS) which will transmit the necessary information via the existing cellular communications infrastructure. Evaluations of position determination accuracy were carried out using a variety of onboard equipment configurations. The authors also evaluated the reliability of the digital cellular communication protocol in communications between the vehicle and the center. The results allow to establish the main guidelines for the communication method between onboard equipment and center. Also, quantitative knowledge of reported position accuracy is obtained for assisting actual operation of the system.

The paper presents a new vehicular emission simulation method, aiming to improve the prediction of the overall vehicular emission in terms of engine emission performance characteristic of the early design stage. The method helps to optimize the matching performance of the vehicle and the engine by reducing the number of parameters to fewer engine running points.

A new approach using a normal vector is given to detect collision and interference between 3D objects. By adding a surface normal vector to every vertex of polyhedron and curved entity surface, and getting intersection, the remainder length of the normal vector is calculated, and judgement is made whether two bodies are intersected. The approach can detect collision interference and calculate collision distance and directional distance in assembly planning. Furthermore, some measures are taken in order to increase algorithm efficiency and avoid any missing in detection.

Mathematical models have been developed to predict swing behavior of vehicles with rear wheels locked during braking. From the model an exponential function is obtained to describe angular deviation of the vehicle, and factors, which are found to have an effect on it are analyzed. Research indicates that for each vehicle at a sudden severe braking there is a critical speed at which the vehicle will not yield dangerous deviation even though the rear wheels lock. Above the speed, however, though deviation would happen, there is a time interval in which the swing angle would rise gently it can therefore give the driver an opportunity to adopt some method to avoid the accident.

The fuzzy control is one of the promising control strategies in controlling the dampings of a semi-active automotive suspension. The focal point of the fuzzy damping control is how to consider the relative large degrees of freedom of the vehicle system under control and how to determine the control parameters of the fuzzy controller. In this paper, a seven degree of freedom vehicle ride model with semi-active suspension and damping fuzzy controller is proposed. For the parameter identification of the fuzzy controller, a new local improvement genetic algorithm is derived. Based on the proposed GA method and fuzzy control theory, the damping fuzzy control of the seven degree of freedom vehicle ride model is simulated and problems in the implementation are solved. An practical example is given.

To implement virtual machining and to optimize the process planning, forecast and measure processing quality, an architecture of virtual machining and measuring cell (VMMC) based on agent was put forward. It is a concurrent virtual system with multi-agent and CORBA. Some basic problems on this architecture are researched in this paper, and solutions are found. Adopting the broker-agent architecture, this system is better in openness and extensibility and its architecture is more flexible. The foundation of this architecture makes the cooperation more harmonious between VMMC and others such as CAD/CAM system and machining plot on manufacturing network. It lays a good foundation for development in the future.
