Ambitious government regulations and strong customer demand for green vehicle technology such as higher-mileage vehicles, push car and truck makers to find and exploit every opportunity to make designs fuel-efficient. All systems are on the table for re-engineering — body, interior, chassis, electrical, and electronics and powertrain.

To succeed, automakers must reduce aerodynamic drag without sacrificing cooling and cabin quietness, reduce vehicle weight while still meeting strength and durability needs, reduce rolling resistance in innovative ways, improve the combustion efficiency of engines, and deploy effective exhaust after-treatment devices.

ANSYS comprehensive emissions modeling and simulation tools and best practices improve fuel efficiency via all these means, optimizing vehicle weight with strong and durable composites design, optimizing aerodynamic drag up-front, and downsizing and optimizing engines and powertrain subsystems.

Strong customer demand and governmental push for higher mileage, greener vehicles means that car and truck makers have to develop and deploy electric vehicle and hybrid technology. Companies that bring more fuel-efficient, less expensive hybrid and electric vehicles to market faster will dominate the future automotive business.

Automotive embedded systems and electronics make today’s vehicles more efficient, safe, comfortable and fun. Paradigm changing innovations such as advanced driver assistance systems (ADAS) and autonomous vehicles are just a few years from production. Vehicles will soon be more electronic machines than mechanical ones. However, automotive electronics and automotive embedded systems drastically increase the complexity of a vehicle, and vehicle makers struggle to manage the resulting safety and reliability issues.

Vehicle makers and suppliers must adopt standards such as ISO26262 and AUTOSAR that reduce complexity and enhance safety. However, this must be accomplished while drastically reducing the time to market.

ANSYS simulation software enables faster, more robust engineering of antenna and radar development, EMI–EMC, signal integrity, chip–package systems, infotainment, human-machine interfaces, telecommunications and electronics cooling. ANSYS tools are revolutionizing development of controller software via high-fidelity, fast-running, model-based systems engineering solutions to create models for controller software verification. Certified automatic embedded code generation tools eliminate the need for controller software validation.

Vehicle companies are constantly wary about major quality assurance and vehicle safety issues identified late in the development cycle or, even worse, after the vehicles have been manufactured and sold. These situations require either last-minute costly fixes or expensive warranty recalls.

Getting product design right upfront calls for virtual exploration of design alternatives from many different angles, involving variations in manufacturing and operating conditions.

Ansys simulation software enables vehicle engineers to achieve quality assurance and vehicle safety by exploring these variations with speed and confidence. With ANSYS’ Multiphysics solutions, products can be virtually tested under real-world operating conditions that typically involve simultaneous, multiple physical loads.

Persistent parameterized simulation workflow and design exploration tools from ANSYS enable fast study of a wide design space to uncover potential failure modes and quality issues.

Ansys’ high-performance computing tools allow large design exploration studies in short time frames, while adjoint solvers and topology optimization tools enable engineers to make designs robust from the start.
