The basic aim of this thesis is to create a concept design for a small four-wheeled utility vehicle. During the design process, we focus on all important structural units of the vehicle select an appropriate alternative for solution of its general configuration. After this, we describe all relevant structural units of the vehicle and we mention the advantages and disadvantages of the selected solution.

The content of this thesis is analysis of energy flows of the propulsion system in plug-in hybrid utility vehicle. Theoretical part of the thesis deals with electrically assisted turbochargers, which can positively influence engine characteristics. The following part analyses given diesel engine and utility vehicle in simulations in GT-Suite software, with simulations being performed on WLTC driving cycle. The results of the simulations demonstrate the relation between the usage of electrical and fuel energies and the driving cycle and show the engine operation points. By using optimal battery capacity, it is possible to save according to driving cycle more than 50 % energy consumed by the engine, directly influencing the fuel consumption. The results are possible to use as a guidance for moving the engine operation points and for sizing of the battery pack of hybrid utility vehicle according to real life application.

This thesis deals with light utility vehicle design (class N1). Apart from designing vehicle’s appearance, other goals such as finding suitable usage of this electric vehicle type or adapting design to user’s needs and new technologies available were set. Usage of light e-van as a last mile delivery vehicle is proposed and following design process takes this purpose into account. Reasoning behind determining decisions is also given in this thesis. Final design stands out with original shaping, while possibilities of colour and graphics make it easily distinguishable among other vehicles. Design also suggests multiple changes in ergonomics of the vehicle, focused mainly on driver’s comfort and overall adaptation to selected vehicle’s use.

This diploma thesis deals with design concept of three wheel small utility vehicle with curb weight 300kg. At the beginning is short description of some similar vehicles. Analyses of used concepts and descriptions of constructions parts have preceded their choice. Then is created 3D model in PRO Engineer and calculations of driving output and stress analyses are based on it. In design concept is accent putted on ergonomics, look, practical utilization and manufacturability.

Rollover prevention in Sports Utility Vehicles (SUV‟s) offers a great challenge in vehicle safety. By reducing the body roll angle of the vehicle the load transfer will increase and thus decrease the lateral force that can be generated by the tires. This decrease in the lateral force can cause the vehicle to slide rather than to roll over. This study presents the possibility of using slow active suspension control to reduce the body roll and thus reduce the rollover propensity of a vehicle fitted with a hydro-pneumatic suspension system. The slow active control is obtained by pumping oil into and draining oil out of each hydro-pneumatic suspension unit individually. A real gas model for the suspension units as well as for the accumulator that supplies the oil is incorporated in a validated full vehicle Adams model. This model is then used to simulate a double lane change manoeuvre performed by a SUV at 60 km/h and it is shown that a significant improvement in body roll can be obtained with relatively low energy requirements. The proposed control is successfully implemented on a Land Rover Defender test vehicle. A Proportional-Derivative (PD) controller is used to control on-off solenoid operated valves and the flow is adjusted using the lateral acceleration as a parameter. Experimental results confirm that a significant improvement in body roll is possible. AFRIKAANS : Omrolvoorkoming in Sportnutsvoertuie bied geweldige uitdagings in terme van voertuigveiligheid. Deur die rolhoek van die voertuig te verminder word die laterale lasoordrag verhoog en word die laterale krag wat die bande kan genereer minder. As die laterale krag genoeg verminder sal die voertuig eerder gly as omrol. Die studie ondersoek die moontlikheid om stadig-aktiewe suspensiebeheer op 'n voertuig met 'n hidropneumatiese suspensie te gebruik om bakrol te verminder en dus die omrolgeneigdheid van die voertuig te verlaag. Die beheer word toegepas deur olie in elke hidropneumaties suspensie-eenheid individueel in te pomp of te dreineer. 'n Werklike gas model word gebruik om die supensie-eenhede asook die akkumulator, wat die olie aan die suspensie voorsien, te modeleer. Hierdie modelle word in 'n gevalideerde volvoertuig ADAMS model geïnkorporeer en 'n dubbel laanverwisseling word gesimuleer teen 60 km/h. Die resultate toon dat 'n beduidende verbetering in die rolhoek moontlik is met relatiewe lae energievereistes. Die voorgestelde beheer is suksesvol op 'n Land Rover Defender geïmplimenteer en 'n Proportioneele-Differensiaal (PD) beheerder word gebruik om die aan-af solenoїde kleppe te beheer terwyl die vloei aangepas word na gelang van die laterale versnelling. Eksperimentele resultate bevestig dat 'n beduidende verbetering in bakrol moontlik is. / Dissertation (MEng)--University of Pretoria, 2012. / Mechanical and Aeronautical Engineering / unrestricted

Optimizing city logistics is a topic of great importance for big cities today. Even though the environmental- and economical consequences of the increasing goods transportation fleet has been present for quite some time, actions from affected stakeholders has not been taken until just recently.  In this brief 9 week project the aim has been to,  from a design point-of-view, in this complex topic, give a suggestion and raise a discussion onto how goods transportation in cities can be made in the future.  The basic idea is to get the consignments as close to the consignees and their travel patterns as possible. Public transportation networks are an existing grid where people are moving around and can potentially be used for combined transport of goods and people. The outcome of this concept is focusing on light parcel delivery towards private consignees, due to the increasing e-commerce trend. By using small transporter vehicles connected to buses, light parcels can be distributed throughout a city and easily accessible for consignees at the bus stops.  The transporter vehicle developed through this project aims to conceptualize connectivity and integration between mobility and parcel delivery services, to ease the every day life of urban citizens as well as decrease the environmental- and economical impacts which the distribution vehicle-fleet of today entails.  The design of the transporter vehicle is an interpretation of how a autonomous distribution vehicle can look like in a future city environment where the integration of public-utility-vehicles is of greater importance.
