Ansys and Subaru collaboration aims to power HEV design

Share this on social media:

Subaru is pioneering a new control system that aims to deliver unrivalled safety and reliability performance for their next-generation hybrid electric vehicles (HEVs) using ANSYS embedded software solutions. ANSYS enables Subaru Corporation engineers to quickly and accurately generate highly sophisticated software code that ensures the operational reliability of key, interconnected HEV systems to help keep drivers safe on the road.

Designing electronic control units (ECUs) that effectively manage and maintain safety, performance and energy efficiency is a top priority for HEV (hybrid electric vehicles) designers. Synchronising and tightly integrating these components requires a faultless control system to ensure that safety-related, mission-critical functions, such as steering and braking, are fully operational in the wake of unpredictable events that could trigger a system failure.

Subaru engineers leverage ANSYS SCADE to rapidly and precisely design and validate embedded software for the new e-Boxer system. Increasing development automation to 95 per cent with SCADE, Subaru dramatically expedites software code creation by nearly eliminating the need for human intervention. This substantially increases productivity and significantly reduces costs, production time and the amount of documentation required for final code verification.

'ANSYS SCADE plays a pivotal role for driving the end-to-end creation of highly complex ECU software code with unparalleled speed, efficiency and accuracy,' said Yuji Kawakami, senior engineer, Electronics Engineering Department at Subaru Corporation. 'Utilising SCADE increased our development automation by 15 per cent, permitting us to swiftly innovate new ECU technology and accelerate its path to market faster than ever — delivering a major competitive advantage.'

'ANSYS SCADE is a critical, industry-leading tool for cost-effectively automating the complicated process of developing ECUs, which are comprised of countless lines of underlying software code and must comply with strict industry regulations,' said Gunther Siegel, senior product line director at ANSYS. 'By leveraging SCADE, engineers can expedite the creation of accurate, highly reliable, mission-critical code that keeps HEVs running at peak performance and industry leaders like Subaru Corporation at the forefront of HEV design.'
