In today's modern vehicles the number of the builtin electronic control units (ECU) is growing, which provide service to the control, regulation, safety and comfort systems, such as the transmission control, braking, stability control, navigation and entertainment systems. The more sub-function will be connected, the more difficult will be the vehicle's electrical system. As the result of the growing complexity a need was born to form a uniform software architecture. Such a uniform structure is provide by the AUTOSAR (Automotive Open System Architecture) standard.
The thesis is written at Robert Bosch GmbH., int the section of automatic transmission control development department.
The thesis aims to describe the AUTOSAR architecture and the main parts of the standard. The main functions and modules of AUTOSAR are also part of the document with particular attention to the AUTOSAR operating system.
Another essential part of the paper is understanding the embedded real-time operating system which was developed at Robert Bosch GmbH based on the basic functions, features and in comparison with the AUTOSAR-OS.
Finally, taking into account the requirements of AUTOSAR standard a selected function will be implemented. To prove that the function is correct a specific function test plan and test execution will be documented
