Survey of the AUTOSAR Complex Drivers in the Field of Automotive Electronics

The Complex Device Driver is a loosely coupled container, where specific software implementations can be placed. The only requirement to the software parts is that the interface to the AUTOSAR system has to be implemented according to the AUTOSAR port and interface specifications. The purpose of the Complex Device Drivers is to fulfill the special functional and timing requirements for handling complex sensors and actuators. It is used to handle the tasks related to the strict timing. The Complex Device Drivers are to some extend intended as a migration mechanism. If interfaces for extensions are defined according to the AUTOSAR standards new extensions can be implemented according to the AUTOSAR standards, which will not force the OEM nor the supplier to reengineer all existing applications.
