AV simulation solution offers virtual testing, development environment
The latest release of ANSYS Autonomy, part of ANSYS 2019 R3, is designed to enable engineers to develop safer autonomous vehicles (AVs) through advanced closed-loop scenario simulation, automated driving and control software development, functional safety analysis, and sensor, camera, lidar, and radar simulation. Using simulation to virtually test AVs, says the company, is the only viable option for validating systems safety and accelerating AV development.
“In ANSYS 2019 R3, ANSYS Autonomy integrates ANSYS flagship products into a comprehensive virtual testing and development environment for AVs,” says Eric Bantegnie, vice president and general manager, systems business unit at ANSYS. “Combined with ANSYS’ comprehensive partner ecosystem, our leading-edge solutions enable customers to accelerate the future of safe autonomous driving.”
ANSYS 2019 R3 extends the ANSYS SCADE family of products with the launch of ANSYS SCADE Vision, which enables customers to evaluate the safety of AI-based perception software systems and reduce object detection defects in autonomous systems. ANSYS SCADE Vision, says the company, drastically reduces the cost of AV perception software testing, enhances safety, and drives high value from AV data.
With the new release, ANSYS SCADE Suite is designed to enhance important features required for developing the most advanced automotive systems and the embedded software that controls these systems for autonomous vehicles. ANSYS 2019 R3 includes improved AUTOSAR support in SCADE for ISO 26262-certified code generation and software component design.
In addition to ANSYS SCADE Vision and ANSYS SCADE Suite, ANSYS 2019 R3 includes multiple tool enhancements to ANSYS VRXPERIENCE Driving Simulator powered by SCANeRTM, ANSYS VRXPERIENCE HMI, ANSYS SPEOSTM and ANSYS® HFSSTM SBR+. Updates to ANSYS VRXPERIENCE provide innovations in scenario simulation, sensors, sound simulations, and virtual reality (VR); the software also now offers SPEOS Live Preview.
NSYS VRXPERIENCE HMI now allows users to run and interact with embedded software in VR as a software-in-the-loop model. These updates to the ANSYS VRXPERIENCE product family, says the company, enable developers to virtually simulate and validate numerous scenarios without the cost of physical prototypes or physical road miles.
While ANSYS SPEOS continues to extend optical simulation into the ANSYS Multiphysics platform, says the company, SPEOS Live Preview helps designers accelerate their design innovation thanks to GPU acceleration, enabling quick design iterations to improve design optimization and robustness. ANSYS 2019 R3 also includes the SPEOS Road Library for Sensors Simulation, a comprehensive retro-reflecting materials database.
“ANSYS SPEOS provides early insights into the optical performance of our designs. It allows for fast iterations on multiple virtual prototypes to optimize the appearance and performance of vehicle lamps, earlier in the product design phase,” says Hiroaki Yachi, Chief, Toyota Customizing & Development. “With SPEOS Live Preview, powered by GPU technology, our engineers can run real-time optical simulations and explore alternative virtual prototypes — reducing costs and development times.”
In ANSYS 2019 R3, ANSYS electromagnetics suite includes new features for engineers tackling complex autonomous vehicle engineering challenges. ANSYS HFSS SBR+ now includes creeping wave physics, which delivers greater accuracy for predicting radar cross section (RCS) of large targets with curvatures — enabling engineers to achieve a more precise RCS reading of objects including shadow regions. In addition, says the company, Accelerated Doppler Processing simulation technology added to ANSYS HFSS SBR+ revolutionizes the way automotive companies validate the safety and performance of radar systems in autonomous vehicles — empowering engineers to test vastly more traffic scenarios than would ever be possible with physical road tests.
With the release, the company also introduces ANSYS Minerva, a knowledge management product for critical simulation expertise. ANSYS Minerva, says the company, improves productivity and maximizes business value from existing engineering technology investments by providing model-based system engineering, simulation process, and data management, lifecycle traceability, process integration, design optimization and simulation-driven data science capabilities. ANSYS Minerva is critical for managing the volume of simulation data required for testing complex systems, such as AVs.
The ANSYS semiconductor portfolio of power efficiency, power integrity, and reliability solutions achieve ISO 26262 certifications to enable automotive integrated circuit designers to meet rigorous safety requirements for AV applications. Auto chip makers can leverage ANSYS PowerArtist, the ANSYS RedHawk family and ANSYS Totem multiphysics simulations for all ISO 26262 safety-related projects for any ASIL level.
