There has been an amazing growth of software used within automobiles in recent years, with cars quickly becoming super computers on wheels. The challenges facing engineers developing embedded software for automobiles are great, and cover a very broad range of issues.

This white paper introduces and discusses the issues that face embedded software engineers who are developing automotive software, including:

  • Types of Automotive Software
  • Safety Development Standards inc. ISO 26262
  • Security in Automotive Embedded Systems
  • Reusable Software Platforms inc. OSEK & AUTOSAR
  • Software Architecture Considerations

System designers are now faced with the challenge of providing safety and functionality as part of the same system. In many cases safety critical systems have to support feature rich graphical interfaces, responsive networking communications, diagnostics, data storage and much more. Due to the rigours of developing safety critical software the development costs are high and it would not be feasible to develop all the software used within the system to the highest safety level required.

This means that within a single system there may be several different levels of safety software.

Therefore the software within the system needs to be partitioned, grouping software of the same safety level together, and assuring that software from lower safety levels can not interfere with software relating to the higher safety levels. Partitioning allows the safety related software to be kept small and concise, whilst allowing the use of third party software modules, which shortens developments times and lowers costs.
