The trend of vehicle industry has been changed due to well development of electronic and information technology , the electronic industry has become an important part of vehicle innovation and research. Taiwan has pivotal status of electric industry in the world, while the opportunity of car electronic was bloomimg, what stratage should Taiwan's electronics company take to hold out the important role ? The mainly research discusses was below: 1. Taiwan has superiority ability of design and production on the semiconductor and the electronic industry, and has the high design flexibility as well as the formidable conformity ability, how the Taiwan electronics industry call into play the core ability and connects with the mainstream of global vehicle industrial, strides in the vehicle to use the electronic industry? 2. By increase of installs the electronic component on vehicle year by year, the vehicle industry push the electronic market growth fast, simultaneously, it provides an oportunity for Taiwan electronic industry; How does the Taiwan electronic industry grasp the opportunity, adopts corresponding ways to enters the global car electronic market? In view of the above questions, this research was doing by collectiing secondary data and the market analysis information, auxiliary to interview several company whom develops automotive electronic products, induces what countermeasures Taiwan electronics company takes by extend their advantage to enter the car electrics industry. The result of this research is found is no matter how ability that company obtain or take what kind of stratage, but the key factor to success was doing daily work practically.

This master's thesis deals with the issue of software tools for automated integrational ECU testing. It is specifically focused on TestAut 2 tool, which is developed by e4t company and used for testing of Skoda cars. Goal of this thesis is comparison of TestAut 2 against similar tools used in automotive industry. This work contains analysis of TestAut 2 tooland description of principles and features of EXAM, MODENA and PROVEtech tools. Set of principles considerd as advantageous is chosen from collected information. Next part of this thesis describes implementation of chosen principles to TestAut 2 tool, verification ofit's functionality and evaluation of it's benefits. In the conclusion author suggests another improvements that can be done.

Sur les différents calculateurs du véhicule, de plus en plus d'organes sont commandés par un interrupteur en silicium (circuit MOSFET) au lieu d'un relais. En plus de la fonction de commutation de puissance, le MOSFET peut comprendre un dispositif de mesure du courant afin de contrôler le pilotage de l'organe et/ou assurer une fonction de diagnostic. On appelle ce type de composant un commutateur intelligent de puissance ou Smart Switch. Il est aussi prévu dans le Smart Switch un dispositif de coupure du courant, en cas d'échauffement interne dû à une surintensité électrique. Avec les dernières avancées technologiques, ces composants peuvent aussi intégrer de la logique de pilotage et une interface de liaison numérique avec un microprocesseur. Cette dernière caractéristique motive lesujet de l'étude afin de définir des lois de protection améliorées contre les échauffements dus à une surintensité électrique.En effet, d’un point de vue de la protection électrique, le MOSFET a été conçu pour obtenir les mêmes caractéristiques qu’un fusible, avec la possibilité supplémentaire d’être réenclenché comme un disjoncteur. Le but est d’étudier les lois de pilotage qui pourraient permettre de mieux suivre les limites thermiques d’un conducteur électrique, en particulier dans les faibles surintensités, de façon à pouvoir diminuer le diamètre (donc le coût) des fils tout en assurant une meilleure protection face aux courts circuits impédants (courts-circuits sur une résistance un peu inférieure à la résistance nominale ducircuit, dans un rapport entre 1 et 3 par exemple). / On various vehicles Electronic Control Unit (ECU), more and more members are controlled bya MOSFET circuits instead of a relay. In addition to the power switching function, the MOSFET maymeasure the current to the steering control of the body and / or to ensure that a diagnostic function. Wecall this type of component a smart power switch or Smart Switch. It is also provided in the SmartSwitch device power failure, if the internal heating caused by electrical current. With the latesttechnology, these components can also integrate control logic and an interface for connection to adigital microprocessor. This last characteristic motivates the subject of study in order to defineimproved protection laws against overheating caused by an electrical current.Indeed, from the point of view of electrical protection, the MOSFET has been designed toachieve the same characteristics as a fuse, with the additional possibility to be reset as a circuit breaker.The aim is to study the control laws that could lead to better monitor the thermal limits of an electricalconductor, especially in low current, so as to reduce the diameter (hence the cost) of son while ensuringbetter protection against short-circuit-impedance (short circuit resistance of a little less than thenominal resistance of the circuit, in a ratio between 1 and 3 for example).
