Reliable dynamic in-vehicle navigation
Having started off from luxury makes and models, in-vehicle navigation systems are now gradually spreading through the entire vehicle fleet, as drivers appreciate their usefulness. Increasingly sophisticated systems are being developed, having much more advanced functions than simple driving …

Tactical Problems in Vehicle Routing Applications
The class of Vehicle Routing Problems (VRPs) is one the most studied topics in the Operations Research community. The vast majority of the published papers focus on single-period problems, with a few branches of the literature considering multiperiod generalisations. All of these problems though, …

Computer vision in vehicle and driver performance
… is performed on a number of participants conducting driving events around a specified route around Oxford, England. Steering, throttle and braking parameters are measured, analysed and characteristic behaviours are resulted. For each participant a professional driving assessor provide by the RDAC …

Energy regeneration and control in vehicle suspensions
In this dissertation we propose a regenerative system that can efficiently extract energy from the suspension while improving the overall dynamical performance of the vehicle. It is shown that typical regenerative devices comprising of a linear-to-rotational element driving a permanent-magnet …

Neural Fuzzy Techniques in Vehicle Acoustic Signal Classification
Vehicle acoustic signals have long been considered as unwanted traffic noise. In this research acoustic signals generated by each vehicle will be used to detect its presence and classify its type. Circular arrays of microphones were designed and built to detect desired signals and suppress unwanted …

Minimizing redundant communication in vehicle networks for city mapping
Modern cars are increasingly equipped with numerous sensors, as well as the ability to send this sensor data over the network to a remote server. This presents the opportunity for a variety of applications that make use of real-time vehicle sensor data. Combined with advances in real-time object …

Predictive control for a throttle regulator in vehicle testing
A method of predictive control is used in the regulation of a vehicles' speed in an environmental test cell with a wind tunnel. The vehicle speed is regulated through the throttle while the vehicle torque is controlled with a dynamometer. The predicted throttle position for the requested speed is …

Modeling and identification of flexible joints in vehicle structures
A simple, design-oriented model of joints in vehicle structures is developed. This model accounts for the flexibility, the offsets of rotation centers of joint branches, and the coupling between rotations of a joint branch in different planes. The model parameters consist of torsional spring rates, …

Simultaneous state and input estimation with applications in vehicle problems
Engineering is about design of materials, structures, systems and interconnections to obtain a desired behaviour. In control engineering the focus is often on systems equipped with sensors whose output is used to provide feedback control and achieve the desired behaviour. A central paradigm in …

Durability Analysis of Helical Coil Spring in Vehicle Suspension Systems
The suspension system in vehicles supports the vehicle's road stability and ride quality by scaling down the vibration responses resulting from road surface's roughness. This research focuses on fatigue life analysis of coil spring component. Static linear analysis is conducted on the 3D model of …

Behavioral Logistics and Fatigue Management in Vehicle Routing and Scheduling Problems
The vehicle routing problem (VRP), is a classic optimization problem that aims to determine the optimal set of routes for a fleet of vehicles to meet the demands of a set of customers. The VRP has been studied for many decades and as such, there are many variants and extensions to the original …

In-vehicle speed adaptation - On the effectiveness of a voluntary system
The overarching aim of this thesis is to study the long term effects of a voluntary speed adaptation system, the Active Accelerator Pedal (AAP), and its effectiveness for different driver types. The papers making up this thesis are based on a study carried out on 284 vehicles and drivers in the …

Finite element simulation of the human body in vehicle side impact
… of an occupant are very complex and difficult to investigate. Industrial research has mainly focused on the impact dynamics of man-made side impact dummies, rather than on the dynamics of real human bodies. Therefore fundamental research of the impact dynamics of real human bodies is rare. The …
