Abstract

The invention relates to the technical field of automotive electronics, and provides an automotive electronic drive abstraction layer architecture based on AutoSAR, and a drive abstraction layer comprises a drive abstraction layer assembly and a drive abstraction layer configuration tool; the driving abstraction layer component defines a plurality of standard interfaces, and the driving abstraction layer configuration tool is used for generating a configuration file; the application layer calls a standard interface and sends an index value to the drive abstraction layer, and the drive abstraction layer reads the index value of the standard interface and indexes the number of an expected drive control assembly according to the mapping relation defined by the configuration file; calling a corresponding drive control component interface according to the number of the control drive component; and the drive control layer calls an AutoSAR MCAL interface according to a configuration file generated by the drive abstraction layer configuration tool. According to the method, the application layer and the drive control are mutually independent, the method can adapt to continuously iterative hardware drive, software is enabled to quickly adapt to the hardware drive in different client projects, and the development cost is saved.
