In this paper, a multi-surface sliding control (MSSC) is proposed for trajectory tracking of 6 degrees of freedom (6-DOF) inertia coupled aerial vehicles with multiple inputs and multiple outputs (MIMO). It is shown that an iterative MSSC design can be carried out to control flight. Using MSSC on MIMO autonomous flight systems creates confluent control that can account for model mismatches, system...
This paper considers the parallel parking problem of automatic front-wheel steering vehicles. The problem of stabilizing the vehicle at desired position and orientation is seen as an extension of the tracking problem. A saturated control is proposed which achieves quick steering of the system near the desired position of the parking spot with desired orientation and can be successfully used in solving...
We present a model of simple cognitive agents, called “creatures”, and their learning process, a type of “social observational learning”, that is each creature learns from the behaviour of other creatures. The creatures may experience fear and/or desire, and are capable of evaluating if a strategy has been applied successfully and of applying this strategy again with small changes to a similar but...
On-road-communications are increasing in relevance, due to the variety of applications for traffic management systems (TMS) and road safety. This interest is enforcing relevant efforts from research community and standardization bodies to support V2V (vehicle to vehicle) and V2I (vehicle to infrastructure) communications. In this framework, an hybrid approach between IEEE 802.11p standard together...
For the realization of the safe driving support system in the Intelligent Transport System (ITS), many studies are conducted to apply the wireless ad hoc network to the inter-vehicle communication. In the wireless ad hoc network protocol used for the inter-vehicle communication, it is necessary to consider the stability of route because network topology changes dynamically according to movement of...
A new model is established for kinetic road traffic flow with disturbance function. It is used to solve the multi-lane, open kinetic road traffic flow simulation problem. The Level of road Service (LOS) is used as the evaluation criteria. It is able to describe the behavior of the changes of the road flows, speeds, occupation ratios and other disturbance factors for the global road traffic flows....
Modelling and simulation (Mod-Sim) tools are becoming a crucial component in the design and evaluation of cyber and physical security systems. Many Mod-Sim tools exist for the elucidation of attack scenarios, characterization of facility vulnerabilities, and the construction and maintenance of optimal protection systems. The growing use of Mod-Sim tools for assessment of physical and cyber security...
Work on Automatic Number Plate Recognition (ANPR) as part of road safety by detecting and deterring a range of illegal road users is currently a key research work undertaken by the School of Engineering and Technology in collaboration with the UK Home Office1 and Hertfordshire Constabulary. A key research problem identified is the lack of an objective and independent assessment process for benchmarking...
Wireless communications between vehicles enables both safety applications, such as accident avoidance, and nonsafety applications, such as traffic congestion alerts [1] with the intent of improving safety in driving conditions. Because cost limited test-bed environments constrain prototype testing, VANET researchers often turn instead to simulation toolsets from which a rich set of environmental scenarios...
Technologies designed to reduce the car accidents are recently being developed. One of type, vehicle to vehicle communication has proven to be highly effective for safer driving. However, effectiveness of vehicle to namdic devices communiation has been overlooked. In this paper, we designed a communication architecture between WAVE and Android. WAVE is the standard protocol of vehicle communication,...
In this paper, based on an in-depth analysis of Geographical Routing Protocol (GRP), especially its next hop selection, we present an improvement for the strategy of next hop selection with a joint consideration of distance factor and hierarchical quadrant. Based on the next hop selection strategy, an Improved Geographic Routing Protocol (IGRP) has also been proposed in this paper, which has a higher...
This paper presents considerations regarding the benefits obtained by implementing traffic control measures on an inter-urban road network. The considerations are based on the results obtained by simulating traffic scenarios on a model road network. These scenarios involve: heavy traffic, over—capacity of the network; medium traffic, under-capacity of the network, but involving an incident. The results...
In this study, implementation of design and simulation programme of a solar energy (photovoltaic panel) supported hybrid electric vehicle was designed, which is considered to be widely used in the 21st century. In the study, DC motor was simulated for a serial hybrid electric vehicle in ICE-generator and photovoltaic panel matlab/simulink environment. Moreover, a .m file was written by calculating...
In order to realize lateral control of vehicles on an automated highway system (AHS), it is necessary to measure and/or predict vehicle deviation from the path to be followed (reference line). In this study, a simple multiple look-ahead distance scheme is proposed; in particular, simple feedback control that uses vehicle lateral deviations at three look-ahead points is proposed. Simulations are conducted...
The penetration levels of plug-in electric vehicles (PEVs) is expected to rapidly increase within the next few years due to global trend of energy saving and environmental protection. It is well-known that uncoordinated charging of PEVs in residential distribution feeders will have significant negative impacts on grid performances causing increased losses, poor voltage regulations, network congestion...
Vehicle Routing Problem (VRP) is a famous combinatorial optimization problem and it has been extended to a multi-objective optimization perspective. This paper targets solving VRP with stochastic demand (VRPSD) under the constraints of available time window and vehicle capacity. The objective of the problem is to simultaneously minimize total travelling distance and total drivers' remuneration. This...
Ten years has passed since the Large-scale Retail Store Law in Japan was enforced and store modifications have been planned among many large-scale shopping centers. In such modification plan, parking lot improvement is also carried out at the same time in many cases. By this research, not only knowledge and experimental rules, about the improvement effect of user service of the parking lot layout...
Continuous vibration energy of vehicle body is converted into heat and dissipated in the air when it is driven. The service life of shock absorber will be reduced at high temperature. An energy regeneration system is designed in this paper to convert vibration energy of vehicle body into electrical energy, which prolongs the driving range of electric vehicle. The dynamic model of shock absorber is...
