Cummins Integrates AUTOSAR, ISO 26262, and Model-Based Design for Faster Product Development and System Simulation

“Implementing Simulink unlocked simulation-based product development, enabling Agile development. This approach integrated the software workflow with the product features to deliver a higher quality product in a shorter time and better aligned with OEM expectations and approaches.”

Key Outcomes

  • Simulation-based product development to enable Agile development
  • Architecture-driven design, which enables coding
  • Connected software workflow (integration of control model with plant model and product data, use cases–product features in simulation environment, higher quality product in shorter time)

Software-defined features are becoming a key differentiator for the automotive, industrial automation, and energy industries.

Cummins specializes in power solutions that cross these and other industries.

In automotive, Cummins needed a way to better meet the increasingly demanding product requirements from OEM customers, such as fuel economy, performance, emissions, and electrification. It wanted to build integrated controls software and system simulation architecture to improve safety and cybersecurity, shift to a powertrain-focused approach to anticipate customer requests, and improve the speed and quality of development efforts.

To address this opportunity, Cummins used Simulink® as the integration platform. It used the AUTOSAR software architecture and expanded its hardware capacity with distributed modules. This approach increased compatibility and interoperability, mixing the classic AUTOSAR and an adaptive AUTOSAR approach to address the needs of the application. Cummins selected AUTOSAR to leverage its physics-based modeling approach (versus regressing and curve-fitting gathered data) and employed Simulink to enable the adaptive features and streamline the integration.
