Resolving Visual “Edge Cases” Leads to Safer Autonomous Vehicles - White Paper

ANSYS SCADE Vision is a powerful software tool that can address inherent weaknesses in AI-supported perception systems for autonomous vehicles by pinpointing hundreds of potential edge cases quickly and affordably. Edge cases are objects in a traffic scenario that have less recognizable shapes than standard traffic signs and automobiles, such as a baby stroller or a person in a wheelchair. Obviously, misclassifying such objects poses a significant safety risk.

SCADE Vision minimizes the cost of edge case resolution and perception system validation by automatically detecting the weaknesses in these systems. As it reviews video-based sensor data while exercising AI-based perception system algorithms, SCADE Vision augments key areas for closer analysis. Based on that augmentation, which is intended to reproduce the wide variety of conditions that a deployed system will encounter, SCADE Vision automatically identifies and flags any abnormalities, with no human intervention.

Early adopters of this innovative technology have reported a 30X acceleration in detecting edge cases compared to manual methods. Perception engineering teams can achieve a significant time, cost and safety advantage by capitalizing on this advanced technology from ANSYS.

ANSYS NVH Solutions for Electric Motors

Simulating the noise, vibration and harshness (NVH) of an electric motor is important for proper electromagnetic (EM) and vibro-acoustic design of electric vehicles (EVs). This paper describes ANSYS’ solutions to characterize the NVH effects of an electric motor early and accurately in the design cycle to improve vehicle performance and safety. These solutions lower development costs and help support electric mobility (e-mobility) — an application resulting from electrifying transportation. ANSYS solutions enable carmakers to reduce the NVH of electric vehicles, improve customer satisfaction and gain competitive advantage in the automotive sector.

Multiphysics Reliability Signoff for Next-Generation Automotive Electronics Systems

Automotive electronics systems depend on an ever-increasing number of electronic sensors and processing elements, which allow for 360-degree surveillance and object identification/classification. Designing and verifying these systems is, however, as complex as the systems themselves.

This white paper examines how automotive chip designers can achieve the stringent safety and reliability requirements for advanced FinFET designs. It explores analysis solutions for electromigration reliability (EM), electrostatic discharge (ESD), thermal reliability, statistical electromigration budgeting (SEB) and functional safety.

Rapid Optimization of Electrical and Thermal Characteristics of Electric Vehicle Batteries

Battery powered electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been gaining market share as the public’s environmental concerns and the depletion of fossil fuels drive the demand for better fuel efficiency. In this white paper we describe a six-step multiphysics simulation involving electrical and thermal parameters to design and validate any battery model. As a case study, we present the battery design for Volkswagen Motorsport’s I.D. R Pikes Peak, which achieved a stunning, record-breaking victory in the 2018 Pikes Peak International Hill Climb.

An Integrated Simulation Platform to Validate Autonomous Vehicle Safety

Autonomous driving systems rely upon sensors and embedded software for localization, perception, motion planning and execution. Autonomous driving systems can only be released to the public after developers have demonstrated their ability to achieve extremely high levels of safety. Today’s hands-off autonomous driving systems are largely built with deep learning algorithms that can be trained to make the right decision for nearly every driving situation. These systems, however, lack the detailed requirements and architecture that have been used up to now to validate safety-critical software, such as that which controls commercial airliners. Road testing is clearly an essential part of the development process, but billions of miles of road testing would be required to validate the safety of autonomous driving systems and software. Simulation is needed to make verification and validation of the operation of autonomous vehicles a practical endeavor.

Managing Changing Quality Needs in Automotive and Consumer Product Industries

As user experience and shared brand or product perceptions effectively dictate purchasing decisions, exceeding customers’ expectations in a cost-effective manner is an imperative for manufacturers. Because design trends change so rapidly, a lengthy development cycle may produce outdated products. To optimize time to market, product stakeholders must improve their efficiency in both product and process design to deliver first-time-right products. New sophisticated quality and visualization tools can help predict manufacturing variation and its impact on perceived quality at an earlier stage, when issues can be addressed with minimal cost. In this white paper, discover how preliminary quality assessment is becoming a must-have in current design processes — for a more streamlined product development lifecycle, with a shortened lead time from concept to production.

How to Design, Optimize and Validate Safe Laser Headlamps Through Virtual Experimentation

Today, car manufacturers and their suppliers are facing a real challenge: designing attractive laser headlamps that will illuminate the road without blinding drivers and pedestrians. Validating the safety of these headlight systems using physical prototypes would require millions of miles of night-driving testing and cost-prohibitive investment.

Simulation is the only option for adequately assessing how a headlight design will perform under numerous road, weather, lighting conditions. Engineers can perform virtual tests in greater numbers and at faster speeds, while reducing development time and prototyping costs.
