AUTOSAR( Automotive Open System Architecture) is basically to standardize cross ECU communication from different OEM manufacturers. The other main intention is to reduce the future development as all the different layers of the AUTOSAR will become compatible each other. Here the main idea is that most of the modules in controller are having basic functions as same. So even the function name and register mapped names in the lower layers are made same which makes the upper layers to work independently even changing the entire controller of the ECU.
Mainly the AUTOSAR layers are divided in top to bottom layer as :
- APP
- Run Time Environment (RTE)
- Service Layer
- ECU Abstraction Layer(ECAL)
- Microcontroller Abstraction Layer(MCAL)
The idea is so fine that in future it will be even good in implementing robotics, where the robot can change its parts which have same lower layer calls and every other components will remain the same as in the science fiction movies.
