Starting control is the key issue in the development of automated mechanical transmission(AMT). Based on the analysis of the control principle for keeping the engine speed instant, this paper presents another method to keep the engine speed instant while starting by controlling the engine torque. With the coordinate control of the engine and clutch, this control strategy can help the vehicle reduce...
This article systematically studies drivers' behavior pattern before accidents according to human's activities. In this study, a fuzzy logic control model is built which based on multiple regression theory, multi-objective decision theory and fuzzy logic control method, and practically proved. Results of model prediction preferably coincide with the practical analysis results from the scene. It proves...
A simulation model of cruising taxi operation system is presented. Vacant taxis cruise in the city to search for passengers, and their search strategies are based on drivers' experience and information. The impacts of dynamic traffic flow and signals are taken into consideration through a cell transmission model. These are helpful for regulating urban taxi operation system more efficiently and providing...
Longitudinal slope section of the road is high frequency location of traffic accidents. In order to improve the road safety, the paper was based on the traffic engineering, applying psychology and other theories, and used the advanced GPS, MC5600 and other testing equipments to detect and investigate the road alignment, speed, driver's heart and physiological responses and traffic characteristics...
Uncontrolled intersection does not allocate the driver a clear right of way in time and space, so the left -turn vehicles will conflict with opposite direction straight vehicles and pedestrians when through the intersection. The process of left-turn vehicle passing the intersection is divided into two parts, the first part is the free turning time, and the other is the average waiting time for the...
Vision-based driver assistance is an active safety measure currently under development in various car companies and research institutes worldwide. The paper informs about related activities at The University of Auckland, focussing on stereo vision, performance evaluation, provided test data, and currently developed components.
Considering the great change on human machine interface between the Control-by-Wire vehicle and traditional ones, this paper tries to analysis and adjust the key characteristics of human-vehicle, such as the H-point, eye ellipse, head enveloping line and accessible area and then construct the human characteristics database focusing on the Control-by-Wire vehicle control system. This paper also realizes...
Through the analysis of the behavior of mandatory lane changing and selectivity lane changing, this paper researches the effects of capacity of urban intersection, delays and the probability of rear-end collision resulting from the lane-changing behavior. The models of capacity, delay time and probability of rear-end collision are established respectively, and simulated delay is evaluated based on...
An advanced driving assistance system (ADAS) becomes more and more important since it can improve driving safety. It is composed of a human driver and an automated system called co-pilot. To make it effective, the driver and co-pilot should properly cooperate. Hence, it is very important to define and model their cooperation behavior such that an ADAS can be effectively designed and realized. This...
Building effective Vehicular Cyber-Physical Systems (VCPS) to improve road safety is a non-trivial challenge, especially when we examine how the driver benefits from the existing and proposed technologies in the presence of Human Factors (HF) related negative factors such as information overload, confusion, and distraction. In this paper, we address a human-centric data fusion problem in VCPS. To...
Modern cars are equipped with a variety of sensors, advanced driver assistance systems and user interfaces nowadays. To benefit from these systems and to optimally support the driver in his monitoring and decision making process, efficient human-machine interfaces play an important part. This paper describes the second release of iDriver, an iPad software solution which was developed to navigate and...
Rising vehicle numbers and increased use of private cars have caused significant traffic congestion, noise and energy waste. Public transport cannot always be set up in the non-urban areas. Car pooling, which is based on the idea that sets of car owners having the same travel destination share their vehicles has emerged to be a viable possibility for reducing private car usage around the world. In...
The Advanced Surface Movement, Guidance and Control System (A-SMGCS) is a concept used by the International Civil Aviation Organization (ICAO) to increase situation awareness in airports, providing airport stakeholders assistance with surface operations in terms of surveillance, control, routing and guidance tasks. The main goal is to maintain the declared surface movement rate under all visibility...
This paper documents the speed reduction impacts of intersection control beacon on rural highway on Xu song road of Beijing City, China. To determine the effect of intersection control beacon on stopping behaviors of drivers, a camera was used to collect valid samples at four times. After data preparation, there were 200 valid samples. In order to research the changing of vehicle speed and relationship...
Traffic congestion frequently occurs at main roads in Japan. Traffic congestion causes economic loss and makes energy efficient worse. Therefore untying traffic congestion is required. In Japan, vehicle information and communication system (VICS) is famous for a congestion avoidance system. However, VICS depends on infrastructures. On the other hand, vehicle ad hoc networks (VANETs) are independent...
To solve the problem that traffic safety risks is difficult to identify and compare quantitatively for the new road or accident black spots, the virtual simulation tests (VST) system is put forward combined the numerical simulation. The driver module on vehicle speed control, the vehicle dynamic network solution module, traffic environment 3D model, traffic safety management and control module, human-vehicle-road...
The use of wireless sensor network in the smart traffic control systems is very beneficial and starting to be very promising in the design and implementation for such systems. It will help in saving people time and adapt the intersections traffic lights to the traffic loads from each direction. In this paper we present an intelligent traffic signals control system based on a wireless sensor network...
Incorporation of a good machine vision into mobile device can create a powerful application. With such advancement, mobile users can use their existing smartphone as their third-eye to perceive the world. This paper introduces a framework using the smartphone to increase ambient intelligence and road safety of moving vehicles through traffic sign alert application. The driver is alerted of the incoming...
In the last decade, the design of smart tools applied to the automotive sector is becoming more and more required to support driving tasks and to increase drivers' safety. In this work, a system for the joint analysis of the on board/off board vehicle context is proposed to derive considerations on the driver's behavior and to detect possible dangerous situations. In particular, a cognitive model...
In this paper, an intelligent electric power steering system use with Permanent magnet synchronous motor drive is proposed It is to replace a traditional hydraulic power steering system and implemented in a real light hybrid electric vehicle for automotive application. Some control Technique is applied to yield basic assist logic, return compensation logic, damping compensation logic, and inertia...
