AUTOSAR Methodology in Practice
- 64 Downloads
The partners Daimler, Hella and Vector recognised the great potential of AUTOSAR very early on, and report on their experiences in introducing AUTOSAR development methodology. From several production projects, they have learned where benefits can be easily attained but also note the hurdles that had to be overcome, and they identified obstacles that must still be addressed today.
Functionality as Driver
For Daimler, the key drivers for introducing AUTOSAR were the large number of new functions and their progressive concentration in just a few ECUs. That has resulted in a high increase in communication requirements and made it necessary to use a FlexRay bus system. New basic software (BSW) and a new exchange format were necessary. To handle all bus systems uniformly, the course towards AUTOSAR was set. One of AUTOSAR’s greatest strengths lies in the fact that many new functions are available in a standardised form. This applies to the support of new bus systems — like Ethernet — and...
