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.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.

The approach can detect collision interference and calculate collision distance and directional distance in assembly planning.

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.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.

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.

Adopting the broker-agent architecture, this system is better in openness and extensibility and its architecture is more flexible.
