Safetyand security havealwaysrepresenteda driving force inautomotive engineering. Today, theseperformance criteria are moreimportant than ever, as vehicles continue to grow exponentially in technological complexity.Advanced technologiesdeliver benefits, but also createnew risks and potential failure modes.

With sales of electric vehicles projected to reach$567 billion by20251,the design ofpowertrainsand battery management systemshasbeen broughtto the forefront.Automakersalsohope to capture a share of theglobalautonomous vehicle market, whichwillaccount for$556.67 billion by 20262,placing more focuson embedded control software, perception systemsandsensors.

Before these diverse innovations can becommercialized,theymust be analyzed and verified for reliable performance under every operating condition.Equally important, all electronics must be proven to work together at the system level, which means developing a robust system-level architecture, testing every integration point,and identifying and addressingweaknesses.

The Industry’s Leading Software forAutomotiveModeling, Analysis and Simulation

Mastering thesediverse, complexautomotive engineering tasks may seem overwhelming ―oreven impossible ― but there is good news.Anestablishedleader in engineering simulation for over 50 years,Ansysenablesautomakerstonavigate thecomplexdesign and verificationchallenges associated with electrification,ADAS和其他technologyadvancements.

NavigatingtheUniqueChallenges of Safety and Security

Safer Embedded SoftwareDevelopment

Underlyingtheadvancedelectronicsystemsfound in modern carsare millions of lines of embedded software code that ensure their flawless operation under everydrivingscenario. Ensuring that the overall software model, and every line of code, deliver the desired functionality is critical to protecting the safety of human passengers.To meet the highest safety standards and comply with regulatory guidelines, software engineers must subject this code to rigorous testing.

WithAnsysSCADE, engineers can streamline design and verification processesviaautomatic code generation of ISO 26262critical software up toASIL D. SCADE can beeasily integratedinto existing AUTOSAR development flowsfor software components,eliminating time-consuming manual reviews.

For example,as Subaru created control software code for its first hybrid vehicle, it automated 95% of the development process by relying on Ansys SCADE to generate code for the car’s innovative engine, called the e-BOXER. Today, it only takes Subaruengineers half a day to implement a model for the e-BOXER’s electronic control unit (ECU) once the control logic has been defined. This enables Subaru’s developers to modify the ECU’s logic and architecture much more frequently and easily as they explore continuing design innovations.

Robust, Automated Safety Analysis

Functional safetyanalysis ensures thatautomotiveelectronicsdeliver reliableperformance over time, without system failuresleading to unreasonable risk.Thisanalysismust encompassthe entire electronics architecture,including down to the chip level.

Ansys medini analyze streamlinesand automatesfunctional safety analysisviaa model-based environment thatsupportsexecutingthe safety-related activities required by applicable standards like ISO 26262.It has helped many customersreduce time and costs,without sacrificing analytic rigor.

Forexample, LiTHIUM BALANCE develops battery management system(BMS) solutionsfor electric vehiclesin keeping withthe most stringent safety, performance and reliability standards. By leveraging medini analyze, engineers at LiTHIUM BALANCE quickly and affordably manage the functional safety verification of their BMS designs.

By providing an easy-to-understand, visual representation of complex electronics and their integration points,Ansyshas benefited ZF Friedrichshafen AG, a globaltechnology company that supplies systemsto automakers.Ansysmedini analyze has streamlined and accelerated functional safety analysis for hardware, software and systems―delivering possible efficiencies including an up to 50% reduction in the time devoted to these tasks.

Theemergence of automated drivinghas brought aneven greater challenge:What if componentssuch as sensors are working as designed, but their capabilitiesfall shortunder real-world conditions?Anew standard,ISO 21448,focuses onsafety of theintendedfunctionality (SOTIF). Ansysmedini analyzehelpsengineers not only identifyweaknesses, triggering conditionsandcausaleffects,but alsointerfaces with simulation and testing tools tovalidateperception software和其他ADAScomponents.
