Autonomous Vehicles & ADAS

Autonomous Vehicles and ADAS

Autonomous vehicles (AV) and advanced driver assistance systems (ADAS) bring increased complexity and a need for more testing. Exploring all the required scenarios within product development timing requires advanced simulation and the application of high-performance computing (HPC). Altair technology enables customers to deliver solutions that makes cars and trucks safer today and on the road to driverless mobility.

While the network grows for vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-everything (V2X), Altair simulation is the key to developing new products to support those ecosystems. Antennas are key to creating the seamless and reliable communication needed in all three scenarios. And Altair offers solutions in a wide array of engineering for antennas, from design to placement to communication. Some of the performance criteria for antenna designs can be tested in physical antenna chambers, but despite the huge expense they do not represent a real-world environment. For this, more development teams are simulating device signal strength and data throughput in a virtual cityscape with Altair.

Radar Design and Integration

Design and integration of automotive radars is challenging due to high operational frequencies and has resulted in electromagnetic (EM) simulation being used more often to reduce the long and expensive prototyping cycles of the radar systems. Due to the electrically large size of the vehicle at the radar frequencies, computational requirements can be high for the EM simulations. Altair Feko™ efficiently and accurately simulates radar antenna design as well as the integration aspects, including radome and bumper effects.

Integrated Software for PCB Design

Altair PollEx™ is the most comprehensive and integrated set of PCB design viewing, analysis and verification tools for electrical, electronics, and manufacturing engineers. PollEx transfers data flawlessly between the industry’s most popular ECAD and simulation tools and enables many of the world’s major electronics corporations to quickly visualize and review PCB designs. Its checking tools detect issues early in the design to avoid product failures and simplify manufacture and assembly.

Run and Manage Test Scenarios at Scale

Most AV and ADAS development testing leverages existing on-premises or public cloud HPC environments. Altair Accelerator™ is a best-in-class HPC technology used by all major electronics design organizations to rapidly scale, accelerate, and optimize resources and cost when running millions of simulations. Accelerator is the fastest high throughput scheduler and can process 10 million jobs per hour.

The Next Generation Connectivity

5G Antenna Design and Placement: Feko® is widely used for the design of radio and TV, wireless, cellular, communication, remote keyless entry, tire pressure monitoring, satellite positioning, radars, RFID, and other antennas. Feko’s method of moments (MoM) solver is used for antenna design. Model decomposition is possible with accelerated full-wave methods like multi-level fast multipole method (MLFMM), or asymptotic methods like physical optics (PO), ray launching geometrical optics (RL-GO) or uniform theory of diffraction (UTD).

5G Radio Channel Models Feko wave propagation models have been extended to account for the higher frequency bands and specific characteristics of 5G. This includes the definition of the electrical properties for material transmission and reflection in addition to atmospheric absorption characteristics.

A wideband propagation measurement campaign at 73 GHz in New York City has been used to verify that the Altair ray tracing model is able to correctly predict the propagation characteristics.

5G Radio Networks: Ultra-dense networks will be required in urban areas to meet high data volumes. Feko ray-tracing can analyze large numbers of base stations simultaneously, including new designs such as massive multiple-input and multiple-output (MIMO) antenna arrays on base stations. It has also enabled the virtual testing of elevation spread of departure (ESD) angles in city environments to evaluate network performance.
