According to the characteristics of fast moving nodes, frequently varying topological structures and instable wireless channel quality of Vehicular Ad-hoc networks (VANET), the paper proposed a scheme which the factors such as business demands, network abilities and VANET feathers should be considered comprehensively on designing the routing protocol of VANET. Analyzing variant demands of transmission...
A virtual vehicle model is built by using ADAMS/View. The model is simplified with 95 DOFs equipped with active anti-roll bars in front and rear suspensions. the anti-roll bar on a torque applied to replace the anti-roll bar on the hydraulic motor, and then to simulate the roll bar of the active anti-roll control , Step on the steering wheel angle input their experiment on the vehicles round tests...
Taking urban traffic trunk to control for the study, it points out a number of shortcomings of the present trunk control method and puts forward the method that for the urban routes traffic characteristics, in a certain period of time, the route cycle and the phase between each two intersections remains the same, while the split is real-time adjusted by certain intersection controller, web-based environment...
Based on the Agent technology's simulation autonomy entity characteristics, this paper has studied the structure of traffic system Agent model and Vehicle Agent's driving control strategy, such as Freedom driving, Following driving, Overtaking driving and so on, and use Borland's Delphi to develop Agent-based Intelligent Traffic Simulation Prototype System -AITSPS under Windows 2000/xp environment,...
The paper adopts the method and the strategy of distributed coordinated control, considering the traffic flow of the adjacent intersections and the road status between them generally, make a real time control to the traffic signal of each intersection. According to the character of traffic system for urban multi-intersections, this method based on single intersection abandons unified signal cycle...
In order to improve the lateral stability of the vehicles at a high speed, a DYC control method is applied to four-wheel steering vehicle control. Through model tracking method, a feedback controller which used direct yaw moment as the controlled output based on fuzzy control theory is designed, meanwhile, classic 4WS control as a feed forward is used to improve the system dynamic response. Several...
In order to improve the lateral stability of the vehicles at a high speed, a parameter self-tuning fuzzy PID Control method to control the yaw moment couple with side slip angle of the front wheel is proposed, and a Fuzzy PID controller is designed. Based on Vehicle dynamic model analysis, and by using MATLAB / Simulink software, vehiclepsilas yaw rate and the side slip angle of the front at the step...
Aiming at the multi-intersections of the urban traffic trunk line, a coordination control by sections is brought forward. The proposed algorithm includes three key steps. Firstly, according to the relativity of each two or three natural intersections on the trunk line, a new intersection is generated, which is thought of as an independent control unit. Some intelligent algorithms are adopted to acquire...
