AUTOSAR Introduction

AUTOSAR Introduction

Hello all, This my first post related to the Autosar introduction, AUTOSAR (AUTmotive Open System ARchitecture) is a revolutionary milestone in the development of Automotive E/E Systems. The development partnership established by leading OEM’s and Suppliers had defined an open reference architecture for ECU software.

The idea behind AUTOSAR initiative is found in 2003 by Automotive OEM’s and Suppliers to avoid re-developing of similar software components.

• Hardware- and software will be widely independent of each other.

• Development processes will be simplified. This reduces development time and costs.

• Reuse of software increases at OEM as well as at suppliers.This enhances also quality and efficiency.

In traditional software development only two layer one is software other one is hardware as shown in above image, in this method we have to write the software as per OEM requirements and we have to deliver the software to the customer.In this method, rework is more and time for software development also more because  of here we are not following any standard.  After Autosar introduced they  made different layers according to their function.

Uniform Producer Independent System Platform which enables Shorter time to market, Less development effort, More products out of one set of components, Improved quality

AUTOSAR layer model offers

Modular Components with defined interfaces

Hardware Independent Software layer

Transferability of modules

Decoupled Basic Software and Application Components using RTE

Conclusion: Above all points are indicating towards a module wise abstracted and robust software which can be reused by any ECU. That is the reason why AUOTSAR has been introduced automotive software development life cycle so that one team has a responsibility to write the specification for the development of ECU and other teams of different expertise can follow these specifications and will develop their software as per standards.

Benefits: Reusability, Choice to get software from different vendors, reduction in complexity, Quality assurance etc
