Integrate highly complex, electric vehicle (EV) and hybrid-electric vehicle (HEV) powertrains and their subsystems and components.
The design of electrified powertrains requires a rigorous development approach and advanced design techniques to efficiently capture the embedded system architecture and associated mandatory requirements, and to implement various safety-critical software components. Behind every complex component of an electrified system is a need for a smart and safe software controller that manages the performance and the safety of the system over the lifetime of the component and the system.
Ansys solutions for electrification of powertrains provide a complete development flow from the system level to the software level, including systems simulation, model-based development, functional safety analysis and embedded software development, to ensure that your powertrain behaves as expected in compliance with the highest levels of safety standards such as ISO 26262 (up to ASIL D) in automotive. With our automatic code generation capabilities, you can significantly reduce the time to certification and ensure the appropriate level of performances and safety.
Significant Challenges Exist to Deliver Future Electrified Powertrain Technology:
Functional safety is critical to ensure that the complex electronics in today's vehicles are reliably delivering consistent performance over time, without system failures.
The traditional approach of using point tools for individual tasks is error-prone and time-consuming. The combination of Ansys medini analyze and Ansys SCADE provides a comprehensive model-based solution for architecture-driven safety analyses that ensure traceability and consistency all along the system development lifecycle. The benefits include:
Ansys SCADE flow supports all software development activities for ISO 26262, ASPICE, AUTOSAR.
EV Powertrain Library is a Modelica library for dynamic multi-domain modeling of electrified systems. It's ideal for design exploration of system modeling workflow.
The library supports multi-fidelity modeling for electrification. Use the library of models to capture electrical, thermal, mechanical, and interactions for electrification controls applications, including electric and hybrid vehicles, electric mobility, auxiliary power electric storage and electrification of engineered systems applications. This complements Twin Builder’s high-fidelity ROM-based workflow.
Optimize component selection, sensor placement and control strategies to improve the system lifespan and efficiency. Tune and optimize controller parameters to improve the driver experience. Validate correct response with respect to functional requirements.
"As Subaru’s engineering team improved its internal processes by using Ansys SCADE, the amount of automation increased to 95% for the code underlying the e-BOXER."
Electrified Power Train
Automotive industry engineers face the challenge of designing affordable, efficient, stable and reliable hybrid electric powertrain technologies almost entirely from scratch – and in an incredibly compressed time frame. Engineering simulation helps to expedite and improve electric powertrain development, providing in-depth insights into complex components and systems.
