With the continuous evolution of the automotive industry, the usage of driver assistance systems is also more widespread as the industry is striving for the development of self driving vehicles. These technologies require more and more high-performance sensors and control units which have to execute functions that require high computing power. This also causes the increase of the firmware size, so the download speed also has to increase, thus requiring a new interface that can provide the sufficient bandwidth. This is how the history of Automotive Ethernet began.

The thesis starts with describing the Ethernet protocol and it’s history in the automotive industry. Then continues with portraying the higher level protocols often used together with Ethernet. After that outlines the Ethernet periphery of the Aurix TC26x microcontroller.

After the introduction of the theoretical background, the design and the implementation of an AUTOSAR conform Ethernet driver is described. The completed module is demonstrated in an application integrated into the environment developed by Knorr-Bremse Fékendszerek Kft.

The thesis ends with the demonstration of the executed test cases and the evaluation of their results which prove the safe and efficient operation of the implemented software module.
