Easing Design Process with AUTOSAR Standard Support

By Eric Tinlot

Today’s vehicles have up to 70 electronic control units (ECUs) supporting many of their in-vehicle functionalities—a result of tougher constraints in areas including security, environment, comfort and safety. All of these functionalities call for simultaneous interactions by sensors, actuators and control units. But with the complexity of signal interactions among ECUs, this can be a challenging prospect. What’s more, these complex interactions and the increasing number of ECU nodes are increasing the amount and complexity of software required.

The Automotive Software Platform and Architecture (AUTOSAR) is an open and standardized automotive software platform and architecture jointly developed by automotive manufacturers, suppliers and tools developers. Because it provides an abstraction layer between hardware and application, the standard allows hardware-independent development and testing of the application software.

Atmel has worked with Vector Informatik to fully support the Atmel 32-bit AVR automotive family devices in AUTOSAR through the MICROSAR bundle from Vector. We have developed a microcontroller abstraction layer (MCAL) for our automotive-qualified AVR devices. These MCAL modules and Vector’s LIN/CAN communication layers are integrated into Vector’s complete MICROSAR environment. This AUTOSAR bundle for the 32-bit AVR family is available from Vector.

The AUTOSAR bundle consists of a microcontroller abstraction layer for AVR automotive-qualified MCUs and Vector Informatik’s LIN/CAN communication layers.
