AVL Software and Functions GmbH provides System FuSa Consultancy for Renesas R-Car SOCs.

Support and Consultancy for Functional Safety to Develop Automotive ECUs That Comply with ISO 26262.

It has become a challenge to efficiently develop complex advanced ADAS/automated driving (AD) systems that comply with functional safety standards.

Renesas provides automotive R-Car System on Chips (SoCs), RH850 automotive control microcontrollers (MCUs), power management ICs (PMICs) and software solutions that support levels ASIL B to ASIL D of ISO26262. However, to meet functional safety standards, the entire ECU system must be compliant, not just the semiconductor devices. Therefore, even with the use of R-Car and RH850 that meet the functional safety requirements, ISO 26262 compliant ECU development requires in depth system level expertise.

AVL has a proven track record of supporting the development of ISO 26262 compliant ECUs from both hardware and software perspectives. Through this collaboration, Renesas customers can leverage the sophisticated safety solutions of Renesas components, and benefit from AVL's expert support for functional safety, enabling reduced development time for ISO 26262-compliant ECUs.

AVL provides not only compliant but also customizable and efficient solutions e.g. opt. production costs

  • Compliance e.g. providing ISO26262 & ISO PAS 21448 compliant process relevant or technical solution.
  • Customization e.g. high flexibility for adaptation of existing solution to customer specific needs OR new development for high/low volumes.
  • Efficiency e.g. optimizing increased production costs due to redundancy as well as ensuring compliance.

AVL portfolio guides you through whole functional safety and SOTIF cycle.
