<objectives>After successfully completing this course, students will be able to:
- describe the basics of serial data communication forms in vehicles.
- evaluate bus systems with regard to their characteristics and the requirements of their use.
- understand the different data communication problems in a vehicle in comparison to data communication between vehicles or between a vehicle and its environment and derive criteria for the development of future communication systems.
</objectives>
