The aim of this study is to examine possibilities and barriers for an introduction of electric vehicles in Sweden. The study has an interdisciplinary approach and thoroughly examines the essential topics which influence the future of the electric vehicle. The study reaches from answering the question on why electric vehicles lost the game to petrol cars in the early 20th century, to sketch how the difference in total cost of ownership will be between electric vehicles and petrol cars for the coming 20 years. Apart from these subjects the main topics of the study are today?s and tomorrow?s situation regarding technology, charging, fuel, market and economic incentives from an electric vehicle perspective.

Denna rapport handlar om utveckling av ett undervisningsmaterial för elever på fordonsprogrammet inom området elektroniska styrsystem. Rapporten beskriver processen från idé fram till färdigt undervisningsmaterial. Detta har tagits fram för att ge eleverna en bredare, mer generell kunskap inom detta ämnesområde än vad som är möjligt att få genom enbart teoretisk undervisning kring utvalda märkesspecifika system.  Undervisningsmaterialet bygger på teoretiska avsnitt som varvas med praktiska övningar kring en mikrokontroller med tillhörande sensorer och aktuatorer. Genom att skapa korta styrprogram som hanterar dessa sensorer kan olika funktioner skapas med hjälp av mikrokontrollen. Detta gör att många av de delfunktioner som används inom fordonselektroniska styrsystem kan simuleras..

Syfte: Syftet med denna uppsats är att analysera utvecklingen av användandet av elektroniska business-to-business auktioner, utifrån ett kundperspektiv i fordonsbranschen. Metod: Denna uppsats präglas av den kvalitativa metoden, för att därigenom ge en ökad förståelse kring utvecklingen av användandet av e-auktioner. Inledningsvis har en litteraturstudie genomförts, varpå intervjuer med representanter för företag i fordonsbranschen gjorts. Slutsatser: Som utgångspunkt har vi valt uppskattningen att e-auktioner skall motsvara 25 procent av den elektroniska B2B-handeln i fordonsindustrin 2002. Det råder en övertygelse om att en betydande missräkning gjorts.

To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

The objective of this paper is to estimate monetary and non-monetary costs for the huntercaused by deer-vehicle collisions in Sweden. These costs include losses in hunting value as wellas time and money efforts related to the handling of wildlife casualties. The calculations arebased on available statistics from 2004 on deer-vehicle collisions involving moose, deer, roedeerand wild boar and on telephone interviews with hunters involved in the tracking of injuredanimals. Altogether, the annual loss in hunting value for moose was assessed to approximately30 million SEK based on the 2004 accident statistics. For roe-deer and fallow deer, thecorresponding figure was approximately 56 million SEK and 1.2 million SEK, while wild boaraccounted for 1.3 million SEK, respectively.

Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.

Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

SammanfattningUnder det senast decenniet har en påtaglig förändring ägt rum i samhället, där miljöproblematiken kommit att bli ett av de mest aktuella och uppmärksammade ämnena. Bland företagen förmedlas ett miljöengagemang som ger intryck av att miljörörelsen på allvarhar lyckats flytta in i näringslivet domäner. Den ökade miljöorienteringen bland företagen har medfört att det blivit svårare att urskilja de företag som utnyttjar den nya ?trenden? för att öka affärsnyttan från de företag som verkligen har ett gediget miljöengagemang. Hur kan ett företag som har ett genuint miljöengagemang förmedla detta på ett trovärdigt sätt utan att försvinna i bruset av den ökade miljöprofileringen? Med utgångspunkt från Klättermusen, ?ett av Sveriges mest miljömedvetna företag? söker denna uppsats svar på hur man kan kommunicerar sitt miljöengagemang på ett effektivt och trovärdigt sätt och hur vida detta skapar positiva attityder hos konsumenter på outdoor marknaden i Sverige.

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

The flow of information in road vehicles intensifies as new techniques develop. Informationsources such as cell phones, navigation equipment and radios demand the driver?s attentionwhile he or she must stay focused on the road to perform a safe driving. Today the visualinformation inside the vehicle is mostly located on the dashboard, which forces the driver tolook down when shifting attention between the environment outside and the informationinside the vehicle. One way to avoid this is to useHead-up Display (HUD), a technique thatprojects information in the visual field of the user.This master thesis has been performed in cooperation with Scania CV AB, a world leadingtruck producer.
