In the automotive world, the number and the diversity of systems implementing embedded computers continue to increase. After a presentation of the different families of automotive systems and some examples (current, trend for futur), we will go through the main requirements and constraints of automotive systems: environmental constraints, reliability, safety, security, diversity of users and use cases, costs, high volumes, diversity of markets and car manufacturers.
Second part of the presentation will address the following points through examples:
- Platform approach: how to optimize schedules and reduce investment
while addressing a variety of system configurations growing.
- System integration: how to optimize the architecture and reduce the
number of embedded computers.
- System development and validation: planning constraints, methods and
tools
