Influence of a reconfigurable wheelbase on lateral vehicle dynamics

This thesis describes the concept of a reconfigurable wheelbase for a car as a way to improve agility at higher velocities. Altering the longitudinal position of each wheel with respect to the centre of gravity, leads to a change in lateral wheel forces. This affects the car's yaw rate, therefore making it possible to influence its agility....

An alternative design for traffic intersections with work zones by using pre-signals

The lane closures caused by the work zone at the approaches create a negative impact on the operational effectiveness of the signalized intersections. This paper presents an innovative design for intersections with work zones to improve the intersection’s practical capacity. In this design, the lanes in the leg with work zone can be used...

Mixed Skyhook-Unsprung Negative Skyhook suspension control for the improvement of Ride Comfort of In-Wheel Motor vehicles

In-Wheel Motor (IWM) vehicle design introduces a lot of benefits for manufacturers. However, it also decreases the ride comfort in the mid-range of perceivable frequencies. The Unsprung Negative Skyhook (UNS) damper control method offers ride comfort improvement in the same frequency range but has its limitations. This thesis proposes two...

Vehicle Dynamics Control Using Control Allocation

Advancement of the state of the art of automotive technologies is a continuous process. It is essential for automotive engineers to combine the knowledge of vehicle dynamics and control theory to develop useful applications that meet requirements of improved safety, comfort and performance. A road vehicle is equipped with several actuators that...

Adaptive Observer for Automated Emergency Maneuvers: Fusing cost-efficient onboard sensors with computer vision into a robust estimate of sideslip angle using online covariance calculation

One of the most promising ideas in autonomous vehicle control systems is letting the vehicle drive autonomously outside the normal, linear, operating region and letting it "drift". By doing so, the maneuverability of the vehicle could be enhanced. To enable systems that can control this behaviour, estimation of certain vehicle states is needed...

Dynamic Wind Farm Control using the WFSim flow model

Renewable energy is becoming more and more important in today's society. Wind energy plays an important role in the production of renewable energy. Due to economic advantages, wind turbines are often sited close together, creating wind farms. As a result, the wind turbines in the farm become interconnected due to the wakes of the turbines. In...

Lateral vehicle dynamics control and vehicle state estimation: A tyre force measurement based approach

In assessing and controlling vehicle dynamics, tyre forces are the most important variables as they are the only point of interaction with the road. Estimating tyre forces is difficult because of their nonlinear characteristics. Therefore, most of the lateral vehicle dynamics controllers and estimators in the literature use a tyre model that...

Safe Interaction Between Lateral and Longitudinal Adaptive Cruise Control in Autonomous Vehicles

According to the statistics, driver error is the main reason for the road accidents: this has motivated an intensive research on intelligent vehicles equipped with automated driving technology, active safety and driver-assistance systems so as to enhance the safety of drivers, facilitate vehicle controllability and stability, and improve driving...

Global Chassis Control and Braking Control using Tyre Forces Measurement

Mobility and traffic safety is a major concern in the society today. Many accidents take place because the vehicle is not following the trajectory that the driver desires. To avoid such accidents, an increasing number of active safety systems are introduced in modern vehicles. Still, most of the time, those systems are designed independently,...

Dynamic control of salt intrusion in the Mark-Vliet river system, The Netherlands

The Volkerak-Zoom Lake is an enclosed part of the estuarine delta in the southwest of the Netherlands and exists as such since 1987. The current freshwater lake experienced a deterioration in water and ecological quality. Especially cyanobacteria are a serious problem. To solve this problem it is proposed to reintroduce salt water and tidal...
