Ett produktutvecklingsprojekt har utförts på Högskolan i Skövde under våren 2017 i samverkan med företaget China Euro Vehicle Technology AB (CEVT). CEVT arbetar med forskning och utveckling inom bilindustrin och ägs av Geely Auto. I och med pågående trend och utveckling mot fullt elektriska personbilar ville CEVT med detta examensarbete undersöka hur volymen mellan framstolarna kunde disponeras, då handbroms och växelspak uteblir. Målet med uppdraget var att utveckla ett konceptförslag av golvkonsol till elbil för att riktas till den kinesiska marknaden utifrån företagets krav och målgruppens behov. Projektet inleddes med en förstudie vilken innefattade intervjuer med målgruppen och experter samt en marknadsundersökning. I förstudien undersöktes användaren och dess behov samt befintliga och framtida bilinteriörer. Framtagen information sammanställdes i en kravspecifikation tillsammans med baskrav från företaget. Koncept genererades utifrån kommande trender samt fastställda funktioner och utvärderades i flera steg. Koncept har utvärderats tillsammans med företaget, genom ergonomisimulering och användartest med en fullskalig prototyp. Resultatet är utformat i två nivåer med en teknologisk överdel, där laddplats för mobil finns placerad samt en interaktionsyta till instrumentpanelen och en underdel med fokus på förvaring. Resultatet innehåller uppdelade förvaringsutrymmen vilka är anpassade till målgruppens användare och deras tillhörigheter. Golvkonsolen är utformad med fokus på flexibilitet, funktionalitet och justerbarhet, då tillbehör kan förflyttas och bytas ut samt att armstöd och överdel kan justeras utefter behov. / A product development project has been carried out at University of Skövde in collaboration with China Euro Vehicle Technology AB (CEVT).

Målet med examensarbetet har varit att samla information åt ett tekniskt konsultföretag för att öka deras kunskap om autonoma system och fordonskommunikation. Statusen på arbetet kring dessa aktiva säkerhetssystem hos olika aktörer och hur systemen implementeras i dagens och framtidens fordon har undersökts genom omfattande litteraturstudier, intervjuer och marknadsanalyser. De autonoma systemen kan samla information från omgivningen genom sensorer och bidra till ett jämnare trafikflöde, ökad säkerhet, lättare bilar och bättre miljö. Genom fordonskommunikationen kan fordon kommunicera med varandra samt infrastrukturen och garantera en säker bilfärd. År 2030 utgörs innerstaden av autonom, elektrifierad kollektivtrafik för att transportera människor på begäran, samtidigt som personbilar till viss del förbjuds. Potentiella behov för människan i en fullt autonom bil har identifierats och diverse produktutvecklingsmetoder har tillämpats för att utforma två konceptuella lösningar för en framtida bilinteriör. Lösningarna visar interaktionen mellan människa och system eftersom underhållning och bekvämlighet blir viktigt i en fullt autonom bil. Respektive lösning är statsägd och rymmer fyra passagerare. I lösningarna är sittplatserna placerade på ett sätt som underlättar kommunikation mellan passagerarna. Passagerarna kan underhållas eller informeras individuellt eller gemensamt via text, ljud och bild. / The goal with this thesis project has been to collect information for a technical consulting company in order to increase their knowledge about autonomous systems and vehicular communication. The status of how various operators work with active safety systems and how the systems are implemented in current and future vehicles has been investigated through extensive literature studies, interviews and market research. The autonomous systems can collect information from the surrounding through sensors and contribute to better traffic efficiency, increased safety, lighter cars and a better environment. Through vehicle communication, the vehicle can communicate with each other in order to guarantee a safe ride. In 2030 the inner city constitutes of autonomous, electrified public transport to transport people on demand, meanwhile private cars are prohibited. Potential needs for the human in a fully, autonomous car has been identified and various product development methods has been applied in order to develop two conceptual solutions for a future car interior. The solutions show the interaction between human and system since entertainment and comfort becomes important in a fully, autonomous car. Each solution is state-owned and holds four passengers. In the solutions, the seats are placed in regard to facilitate communication between the passengers. The passengers can be entertained or informed individually or collectively by text, sound and images.

Cette étude vise à caractériser en soufflerie les mécanismes aérodynamiques à l’origine de la génération puis la transmission des fluctuations de bruit dans un modèle d’habitacle automobile. Le banc d’essai conçu en soufflerie anéchoïque consiste en un écoulement dont la vitesse incidente est modulée par un volet mobile, et qui par interaction avec une marche montante rayonne un bruit aéroacoustique transmis à travers une vitre dans un caisson anéchoïque. L’approche retenue consiste, pendant le temps de maniement du volet, à mesurer et relier le champ de vitesse externe mesuré à l’aide de la technique de vélocimétrie laser par images de particules (TR-PIV échantillonnée à 20 kHz) à la pression pariétale d’une part, puis au champ acoustique interne obtenu par transmission d’autre part. Des outils de corrélation spatio-temporelle sont alors utilisés pour mettre en évidence les zones de l’écoulement les plus corrélées avec les fluctuations d’énergie de la pression pariétale et celles du niveau de bruit intérieur. La fluctuation du chargement aérodynamique de la vitre sous la bulle de recirculation est logiquement liée à l’activité instationnaire de cette dernière, puis plus en aval, au lâcher tourbillonnaire. Quant au bruit transmis dans le modèle d’habitacle, il semble principalement lié aux fluctuations de vitesse dans la couche de cisaillement. Enfin, une procédure spécifique a permis d’évaluer le caractère quasi-stationnaire des variations temporelles des quantités fluctuantes ainsi que la réponse acoustique de la vitre. / This study aims at characterizing in a wind tunnel the aerodynamic mechanisms contributing to the generation and transmission of the noise fluctuations into a car interior model. The test bench designed in anechoic wind tunnel consists of a flow whose incoming flow velocity is modulated by a mobile flap, and which by interaction with a forward-facing step radiates an aeroacoustic noise transmitted through a glass into an anechoic box. The adopted approach consists, during the flap handling time, in measuring and connecting the external velocity field measured using the Time-Resolved laser Particle Image Velocimetry technique (TR-PIV at sampling frequency 20 kHz) to the wall pressure on the one hand, and then to the internal acoustic field obtained by transmission on the other hand. Spatio-temporal correlation tools are then used to highlight the flow areas that are the most correlated with the energy fluctuations of the wall pressure and with those of the internal noise level. The fluctuation of the aerodynamic loading of the window under the recirculation bubble is logically related to the unsteady activity of the latter, then further downstream to the vortex stream. As for the noise transmitted into the cabin model, it seems mainly related to the speed fluctuations in the shear layer. Finally, a specific procedure allows to evaluate the quasi-steady nature of the temporal variations of the fluctuating quantities, as well as the acoustic response of the window.

Interiör inredning i bilar idag är en faktor som konsumenter värderar högt. För att sticka ut i marknaden krävs det att alla delar upplevs högkvalitativa. Det medför att det ställs allt större krav på interiöra komponenter i bilen. Studien är i samarbete med Volvo Cars och mer specifikt deras Perceived Quality-avdelning då det är denna avdelning som fokuserar på upplevd kvalité och arbetar för att Volvo Cars bilar ska upplevas högkvalitativa. En viktig del av den interiöra inredningen är belysning. Denna studie har som mål att besvara hur stora differenser det kan vara på luminansnivåer innan det mänskliga ögat märker skillnad. De metoder som använts är observationer och experiment. Observatörer blev visade fyra olika lysande punkter där deras uppgift var att förklara när de upplevde skillnad samt hur de upplevde skillnaderna. Mätdata insamlades med luminanskamera som sedan analyserades. Data som insamlades redovisades och analyserades. Data användes sedan för att påvisa hur mycket luminansnivåer interiört i bilar kan differera innan skillnad upplevs. / Interior design in cars today is a factor that consumers value highly. To stand out in the market, it is required that all parts are experienced as high quality. This entails that there are increasing demands on interior components in the car. The study is in collaboration with Volvo Car Group and specifically their Perceived Quality department as it is this department that focuses on perceived quality and works to ensure that Volvo Car Group´s cars are perceived as high quality. An important part of the interior design is lumination. This study aims to answer how large differences there can be at luminance levels before the human eye notices a difference. The methods used are observations and experiments. Observers were shown four different luminated points where their task was to explain when they experienced difference and how they experienced the differences. Measurement data were collected with a luminance camera which was then analyzed. Data collected were reported and analyzed. Data were then used to show how much luminance levels interior in cars can differ before a difference is experienced.

The growing demand in the industry towards sustainability and the globalization of manufacturing lead to an industrial climate of constant development and improvements, and automotive interior design is not excluded. In 2017 the European Union declared that the material used to generate the bright chrome surfaces of car interiors (CR VI) is toxic and carcinogenic. This implies that Volvo will ban the use of Chrome VI for decorative parts from September 2024.  Finding a more eco-friendly alternative to replace CR VI not only functionally but also in terms of perceived quality and user experience will be an urgent and decisive action.  In this project, the parameters of gloss, haze, color temperature, and metallic depth are investigated in order to figure out which elements ensure the perceived quality of chrome surfaces.  For this purpose, a user study based on different sensory tests and soft metrology was carried out with 48 people, as well as seven samples, five of them more eco-friendly alternatives. This project aims to introduce a set of tools to assess and guarantee the perception of quality by supporting the development of "chrome-look" surfaces in the automotive interior with new sustainable materials. Through this study, correlating soft and hard metrology, it is observed what makes a surface perceived as "high-quality" and which of the more eco-friendly alternatives could be the most optimal to replace Chrome VI in Volvo's car interiors.
