The safety of navigation of ro-ro passenger ships has been perplexing the shipping circles, while the problem of vehicle safe stowing and securing is an important factor that affects the safe transportation of ro-ro passenger ships. Some specifications are put forward in home and abroad on the research of safe stowing and securing of vehicle on board ro-ro passenger ships. However, it is lacking in...
In this paper, we proposed a new car following model based on the Full Velocity Difference (FVD) model, with the acceleration of the front car considered. Compared with the FVD model, the improved model can simulate the motions of cars starting from a traffic signal more nature. Numerical simulation results show that the stability of the improved model is better than the FVD model, with appropriate...
The paper presents aspects concerning the modeling, driving scenarios and control structures of two classes of vehicular power train systems with continuously variable transmission (CVT). The modeling includes an analysis of the systems' components which include the spark-ignition internal combustion engine, the torque converter, the continuously variable transmission and the wheels. The CVT offers...
Adaptive cruise control (ACC) system is a Driver assistant system, which can provide safe and comfortable driving. Based on the analysis of ACC system, a parameter self-tuning fuzzy-PID algorithm is developed to design the ACC control strategy. According to the traffic condition, the parameters of PID controller are adapted on-line by fuzzy rule. The simulation results show that the parameter self-...
This paper puts forward a method of identification of driver's intentions based on cloud model theory. By divided the steering driver's intentions into 6 interrelated species and corresponded three indexes of identification of driver's intentions with three numerical characteristic of cloud model based on cloud model knowledge, modeling, simulating and identification the driver's intentions under...
In this paper, the design of a formation flight controller is investigated. Each vehicle in the formation is controlled by designing two separate control loops. The formation flight controller placed in the outer loop employs behavior-based control as a distributed control strategy to steer the vehicle by producing acceleration commands and the control system placed in the inner loop is to convert...
Safety is one of main goals of VANET (Vehicular ad hoc Network). In Vehicle Interactive Navigation System, according to vehicle-to-vehicle (V2V) communications vehicle can share its own location within the lane and other information (speed, velocity, acceleration) to the neighboring vehicles so that it allows vehicles to coordinate maneuvers for safety goal such as collision avoidance. Traditionally,...
In the future intervehicle communication will make driving safer, easier, and more comfortable. As a cornerstone of the system, vehicles need to be aware of other vehicles in the vicinity. This cooperative awareness is achieved by beaconing, the exchange of periodic single-hop broadcast messages that include data on the status of a vehicle. While the concept of beaconing has been developed in the...
The emerging vehicular networks will enable a variety of applications for safety, traffic efficiency and driver assistance. However, the highly dynamic connectivity between vehicles makes the vehicular ad-hoc communication especially challenging. Networked Electronic Control Units (ECUs) are increasingly being deployed in automobiles to realize various functions and Controller Area Network (CAN) is...
Millions of road users and pedestrians are killed in traffic accidents each year. The need to increase road safety is one of the major concerns, and the better way to increase safety is to develop systems which are able to automatically drive. The authors have tried to extract the information of sharpness of curves on the road and have presented the system which will provide the intelligent speed...
It is de facto that merging two different streams of vehicles into one single stream poses some degree of inconvenience. As human lives are at stake, a lot of care has to be taken in this area of traffic management. In this paper a proactive merging strategy is proposed, keeping the intersection of ramp and a highway as the main focus. In our algorithm, it is assumed that the vehicles are sensor-enabled,...
We present load characteristics of three-phase 12/8 switched reluctance motor (SRM) for the electric vehicle (EV), driving noise, and accelerating performance of the vehicle. Driving force characteristics of EV using SRM are calculated from the torque vs. speed characteristic. The driving force reaching the wheels is used to overcome the traveling resistance, and works as the propulsion power. Driving...
