AUTOSAR
The automotive software architecture standard that splits controller software into a standard basic layer and application components, so BMS functions can be developed and integrated like parts. Classic AUTOSAR runs on microcontrollers, Adaptive on larger processors.
Example
Data, communication and electronics: an example situation
2500 in a log might mean 25.00 °C, 2.5 V or raw counts. Units and scale must accompany the value.
Read AUTOSAR alongside ARXML in this context. The XML exchange format of AUTOSAR, describing software components and the communication matrix of a whole vehicle — CAN, LIN, FlexRay and Ethernet — in one model. Carmakers increasingly hand suppliers ARXML instead of DBC files.
