Abstract [en]

This paper aims to improve understanding of regional development processes in relation to industry-university links and cluster development. An innovative regional automotive test industry cluster, located in a peripheral region of northern Sweden, is the empirical case at hand. Key findings from our longitudinal investigation show how once the local automotive test industry reached a certain maturity that renewal was sought via developing interregional links with universities. However, due to misunderstandings and imbalance of motives between the respective regional industry and non-local universities, disruptions to the renewal were experienced. Despite such challenges, new university-industry pipelines were able to open and enact renew of the industry clusters development. This occurs through what we term an ‘interregional sensegiving and sensemaking process’ that in our case take place between personal communication and meeting were trust is an important factor. Subsequently, with particular focus on regional industry cluster development and university-industry links this paper contributes to existing literature by showing the potential of applying sensemaking on a regional level and provides relevant implications for theory and practise.

Abstract [en]

The purpose in this paper is to elaborate on the challenges and possibilities in automotive winter testing in Sweden, in particular the use of fleet management and steering robots since this have shown to be an interesting area for future automotive winter testing. Data has been collected from a number of interviews, workshops and survey’s. Automotive manufacturers (OEM’s), Tier 1 suppliers and service providers (e.g. test track owners and winter test entrepreneurs) have contributed in the data collection. In general, the service providers want to take a step closer to their customers in the value chain to provide new or extended services. It is found that the automotive industry is constantly pressed by shorter projects, fewer prototypes and the lack of state of the art test methods. The service providers find the use of remote technologies like fleet management an important part of their service, especially connected to the safety for test-drivers and overall safety on the test tracks. Service providers also see further research in the area of fleet management as a base for future services. Also, the possibility to replay the last run from logged data in the vehicle is stated by automotive industry to enhance the services. The use of steering robots during winter testing can provide the opportunity to run repeatable and standardized test. However, the study shows that the views vary a lot between companies about the usability of the steering robots during winter testing. This indicates that further research on the issue to provide standardized winter testing is necessary. Work to enhance a fleet management solution and a pre-study of the usability of steering robots in winter testing has been initialized; the studies presented in this paper provided a basis for that work.

Abstract [en]

In this paper, a Remote Technology Management (RTM) solution is presented for the purpose to elaborate on how it can bring about opportunities for new innovative services in the automotive winter testing industry. The idea is to visualize how service providers can go from a product focus to a future where they take an active role as an expertise in the testing activities. Based on the premise that technologies like RTM can become a basis for novel services, the activities at a proving ground are described from three actors’ point of view and discussed in terms of service innovation.

Abstract [en]

This report present a pre-study project of AVL-DRIVE measurement system conducted from 27st of July 2009 until 15th of October 2009.The focus of the pre-study was to see how the system, as it is, could be used by the service providers and their customers during winter and summer testing in northern Sweden but also if the system could be extended and further developed to suit their needs. The AVL-DRIVE system is designed for objective assessment and quality control of Driveability based on human experience. Procedures for the objective assessment of the subjective perception of the driver have been used to define the evaluation method and formulas. Experiences acquired from internal and external vehicle benchmarks and Driveability development projects are incorporated in the AVL-DRIVE system. AVL-DRIVE uses different sensors and CAN bus information to capture the most significant data and vehicle parameters, such as, accelerations, engine data, vehicle speed, pedal position and vibrations. These input quantities are collected by the DMU2 (DRIVE Main Unit 2, located in the car boot) and passed on to a PC (Notebook, located at the passenger seat) for further analysis. Ratings for all Driving Modes are displayed online during driving. A rental car, Audi Q5 2.0 TFSI Quattro S-tronic, was equipped with the AVL-DRIVE system. The pre-study consisted of a number of tests, both on public roads including gravel and tarmac, but also on Bosch/ATM test tracks. One use for the system as it is today could be to study the change in vehicle drivability after endurance tests or after longer periods of testing. This could be done by driving a set of specified driving cycles called Fahr Manöver Katalog (FMK) in this report. Another idea put forward by an engineer at a service provider was to use the AVL-DRIVE system to compare certain driving maneuvers with a vehicle directly from the cold chambers and with the vehicle warmed up, to study the effects on Driveability for cold car and systems. Also these tests do not require any ESP, ABS, or ASR activity so the AVL-DRIVE system as it is could be used for this purpose. However, a handling version of the AVL-DRIVE that could also handle ESP, ABS, and ASR interventions would be of great interest to the service providers and the automotive testing in general.

Abstract [en]

Vehicles are becoming increasingly more complex in terms of, for example. Electronic Stability Program (ESP), Antilock Braking System (ABS), Traction Control System (TCS), and Active Rollover Protection (ARP), i.e. several different control systems that have to interact to perform well when driving. Hence, efficient testing activities are vital to ensure that the components and systems in the vehicle are functioning as intended. The testing activities at a proving ground initially seem to mainly incorporate technical aspects that focus mainly on the prototype vehicle and its components. However, services related to automotive testing are also important to ensure professional tests where the actors, here called service providers, are those who supply the proving ground and the subsequent services. Tracks to run the tests on are rather obvious, but there is also a need for administrative services, accommodation, logistics, access to local test drivers for endurance tests, mechanics, information and communication technologies, etc.The research presented in this thesis has studied “Which technologies have the potential to contribute to winter testing activities?”, “How can technologies support the testing activities?”, “How can the actors benefit from technology supported winter testing?”, and the guiding vision trough the work has been to contribute to service innovation in winter testing activities. A premise has been that technology, in particular vehicle dynamics and distributed engineering will be useful to contribute to the vision. The research has an explorative approach to winter testing, since previous research in this area is limited. The research, therefore, has embarked from a topic (i.e. vehicle dynamics) rather than a hypothesis. Still, the research project is based on previous research, specifically a technological framework for the transmission of real-time data from test vehicles to development facilities worldwide. The last three years of research used Action Research (AR) Participatory Action Research (PAR) and Participatory and Appreciative AR (PAAR) as a frame of reference, since it was considered important to involve both researcher and participants in the studies to evolve from the experience in the field and participate in group improvement or service provision changes. This approach resulted in the use of extensive empirical data to find supportive technical concepts for the service providers. Service providers were seen to continuously develop services at the proving ground, while looking for ways to provide better services, e.g. safety on the test tracks and correct and relevant information about the weather conditions. However, it can be argued that there is a focus on the more visible facilities, e.g. related to ice and land tracks, as well as a view of services to make people from the automotive industry comfortable when away from home, e.g. tourism and adventures. These are important. Yet, the advancement of automotive systems and more complex vehicles has “gradually” made testing activities more dependent on technologies. In this context, the technological services provided at the proving ground seem more invisible. This can relate to a perspective on technologies as the expertise area of OEM and Tier1. In turn, such a view makes it difficult to proactively take the next step in providing technological support. Yet, in the studies presented in this thesis it is found that the service providers already act as a competent and trusted partner in the testing activities. Further, the studies show that an upcoming challenge for OEM and Tier1 is the issue of developing well-defined methods to standardize tests. This is one opportunity for service providers to provide new or extended services. Therefore, in this thesis, Remote Test Management, steering robots and objective evaluation of vehicles are explained technically and outlined as being part of such service innovation.

Abstract [sv]

Fordon blir allt mer komplexa med antisladdsystem (ESP), antispinnsystem (TCS), låsningsfria bromsar (ABS) och rundslagningsskydd (ARP) och alla dessa är olika kontrollsystem som måste interagera med varandra för att prestera bra under körning. Därför är tester av dessa system och fordonet av största vikt för att säkerställa att komponenterna och systemen i fordonet fungerar felfritt. Testaktiviterterna vid en provanläggning kan i en första anblick ses fokusera mestadels på prototypfordon och dess komponenter. Men tjänster relaterade till fordonstestning är också av största vikt för att säkerställa professionella tester där vintertestentreprenörerna tillhandahåller provanläggningar och tillhörande tjänster. Förutom provbanor så finns det ett behov av administration, boende, logistik, tillgång till lokala testförare, mekaniker, informations- och kommunikationsstöd mm.Forskningen som presenteras i denna avhandling har studerat “Vilka teknologier som har potential att bidra till vintertestaktiviteterna?”, “Hur kan teknologier stödja testaktiviteterna?”, “Hur kan aktörerna dra nytta av stödjande teknologi under vintertestning?” och visionen under arbetet har varit att bidra till tjänsteinnovation för vintertestaktiviteter. Tanken har varit att fordonsdynamik och distribuerat ingenjörsarbete kan bidra till denna vision. Forskningen har en explorative ansatts till vintertest av fordon eftersom tidigare forskning inom området är begränsat. Forskningen har därför utgått från ett ämne (fordonsdynamik) istället för en hypotes. Samtidigt så har forskningen baserats på tidigare forskningsprojekt, nämligen ett tekniskt ramverk för överföring av realtidsmätdata från testfordon till utvecklingsplatser utspridda i världen. Aktionsforskning (AR, PAR, PAAR) har använts som referensram de sista tre åren i forskningen eftersom det ansågs vara viktigt att involvera både forskare och deltagare i studierna och tillsammans utvecklas från erfarenheterna och delta i tjänsteutveckling. Denna ansats resulterade i användandet av omfattande empirisk data för att hitta stödjande teknologikoncept för vintertestentreprenörer. Observerat är att vintertestentreprenörer kontinuerligt utvecklar sina tjänster på provanläggningarna samtidigt som de söker nya sätt att erbjuda bättre tjänster till sina kunder, t.ex. säkerhet på provanläggningen och relevant väderinformation. Dock kan det ses som att fokuset har varit på provanläggningarna, d.v.s. relaterat till is- och landbaserade provbanor, men även fokus på turism- och äventyrstjänster för människor från deras kunder. Dessa är viktiga men utvecklingen av fordonssystem och mer komplexa fordon har gradvis medfört att testaktiviteterna har blivit mer beroende av teknologier. I denna kontext syns inte de tekniska tjänsterna som levereras på provanläggningarna. Detta kan relatera till synen att teknologier är expertområdet hos biltillverkare och underleverantörer. En sådan syn gör det svårt att proaktivt ta nästa steg och erbjuda teknisk support. I studierna presenterade i denna avhandling synliggörs det att vintertestentreprenörerna redan agerar som en kompetent och trogen partner i testaktiviteterna. Studierna visar också att en framtida utmaning för biltillverkare och underleverantörer är utvecklingen av väldefinierade testmetoder och standardiserade tester. Detta är en möjlighet för vintertestentreprenörer att erbjuda utökade eller nya tjänster och i denna avhandling presenteras Remote Test Management, styrrobotar och objektiv utvärdering av fordon som de teknologikoncept som kan stödja tjänsteinnovation.

Abstract [sv]

VISION Genom samverkan med initiativtagare runt TSS-konceptet skall projektet ha bidragit till att göra E45’an till en europeisk ”Test Route”. Infrastrukturen skall erbjuda testmöjligheter av fordon i en mix av 2G, 3G, WLAN, WIMAX, NMT 450, o.s.v. Projektet skall skapa ett tydligt partnerskap mellan regionens entreprenörsdrivna mindre företag och de stora aktörerna inom två av svensk industris kärnområden (fordonsindustrin och telekomindustrin). BAKGRUND Centrum för Distansöverbryggande Teknik, ”CDT”, och Centre for Automotive system technology and Testing, CASTT, vid Luleå Tekniska Universitet, har den 1/1 2008 startat upp mål2-projektet ”den Intelligenta Inlandsvägen”. Övergripande mål är dels ett heterogent nät i form av en demomiljö med flera typer av transmissionstekniker, dels ett antal utvecklingsprojekt, med sikte på att bygga kunskap, teknik och metod som stödjer den vintertestrelaterade verksamheten inom denna demomiljö. PROJEKTSTRATEGI Ett samarbete med näringslivet både regionalt och nationellt skall säkra att framtagna prototyper tar sig ut på markanden som produkter och tjänster. Kopplingar till nationella projekt inom fordonsindustrin, inte minst Test Site Sweden, säkrar att utvecklingsinsatserna leder till ett vidgat nätverk för aktörerna inom vintertestregionen.

Abstract [en]

This paper presents a way to merge range data into the vehicle dynamic simulation software CarSim 7.1. The range data consists of measurements describing the surface of a road, and thus, creates a close to real life 3D simulation environment. This reduces the discrepancy between the real life tests and simulation of vehicle suspension systems, dampers, springs, etc. It is important for the vehicle industry to represent a real life environment in the simulation software in order to increase the validity of the simulations and to study the effects that uneven roads have on the systems. Furthermore, a 3D environment based on real life data is also useful in driving simulators, when for example, analysing driver behaviour, testing driver response, and training for various driving conditions. To measure and collect data, a car was equipped with instruments and a computer. On top of the car, a SICK LMS200 2D lidar was mounted tilted downwards, facing the road in front of the car. To create the 3D environment, all the individual measurements were transformed to a global coordinate system using the pose (position and orientation) information from a high-class navigation system. The pose information made it possible to compensate for the vehicle motion during data collection.The navigation system consisted of a GPS/IMU system from NovAtel. To reach high navigation performance, the raw GPS/IMU data were post-processed and fused with data from three different fixed GPS base stations. The range data were modified with a Matlab script in order to parse the data into a file that could be read by CarSim software. This created the 3D road used in the vehicle dynamic simulations. The measurements were collected at a go-kart track in Lule°a, Sweden. Finally, tests have been performed to compare simulation results between using a 2D surface (i.e. flat) and a 3D surface (close to real life). It is seen that the simulation results using the 2D surface is clearly different from the 3D surface simulation.

Abstract [en]

The Swedish road administration sees a need to improve the road grip estimation capacity for the Swedish road system. The challenge is to find methods to measure road grip fast and reliable. There where six different system types at the tests in Arjeplog, three continuous, two system measuring road grip through deceleration and one system based on GPS and accelerometers. Two system types used air craft runway tires. The other systems used either studded winter tires or friction winter tires. Test runs where performed and road grip where recorded for three different surface types, old system 2000 ice, polished ice and new system 2000 ice. Weather data was collected during the three days. It is clear that all systems can detect changes in road grip. It is clear that continuous systems hold an information advantage over the sequence oriented systems. For measurements of road grip on winter roads, we recommend that rubber compounds adapted for cold conditions are used, as the resolution of the road grip measurement where better. In extreme condition like on polished ice, studded winter tires increase the road grip significantly.

Abstract [en]

A major challenge for the automotive industry is to reduce the development time while meeting quality assessments for their products. This calls for new design methodologies and tools that scale with the increasing amount and complexity of embedded systems in today's vehicles.In this paper we undertake an approach to embedded software design based on executable models expressed in the high-level modelling paradigm of Timber. In this paper we extend previous work on Timber with a multi-paradigm design environment, aiming to bridge the gap between engineering disciplines by multi-body co-simulation of vehicle dynamics, embedded electronics, and embedded executable models. Its feasibility is demonstrated on a case study of a typical automotive application (traction control), and its potential advantages are discussed, as highlighted below:shorter time to market through concurrent, co-operative distributed engineering, andreduced cost through adequate system design and dimensioning, andimproved efficiency of the design process through migration and reuse of executable software components, andreduced need for hardware testing, by specification verification on the executable model early in the design process, andimproved quality, by opening up for formal methods for verification.

Abstract [en]

The performance of cars has during recent years become increasingly dependent on complex electronic systems used especially for safety but also comfort, performance and informatics. Automotive winter testing activities in northern Sweden is vital to test and try out those systems. A contradiction to increased performance is that faulty software also causes 30 % of severe malfunctions in the functionality of the car. To deal with these problems, as early in the design process as possible, innovative methods to cope with digital abstraction and the physical world in a unified way seems promising. One useful approach, in automotive winter testing, might be to support the possibilities for real-time vehicle simulations of the car in motion. The closer collaboration in the automotive industry might be an incitement for investing in technologies for knowledge sharing. Besides enhancing the product development process, additional knowledge might support innovations. Today, instead of providing parts similar to their competitors and relying on one or two automakers, successful suppliers focus heavily on innovation and on collaboration with a number of manufacturers on a global market. Due to the possibilities to visualize whole processes, the use of simulations seems to support a' seeing first' approach to innovations. Thus, the purpose of this paper is to describe an as-is scenario and a to-be scenario for automotive winter testing to highlight how the use of real-time simulations facilitates innovative methods
