Solve design challenges for autonomous vehicles (AV) and advanced driver assistance systems (ADAS) by simulating real world performance using virtual test drives.

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.

Altair simulation is vital to vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X), AV and ADAS development at our customers. 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, Ultrasonic, and LiDAR 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. Feko® also provides a solution for ultrasonic sensors, and the Altair Partner Alliance offers access to TracePro for LiDAR modeling.

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.

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.

The Use of MBD Modelling Techniques in the Design and Development of a Suspension System

This paper describes the use of Multi-body Dynamics (MBD) modelling techniques in the design and development of a suspension system for a novel autonomous vehicle. The general approach and philosophy is described, whereby MBD techniques are used in conjunction with an independent (parametric) whole vehicle handling simulation. This is supplemented with examples, showing how MotionSolve was used (in tandem with CarSim) to develop the suspension elasto-kinematic geometric properties to meet specific cascaded targets, to optimise a weighing strategy, to predict forces under a variety of quasi-static and dynamic loads, and to estimate response to track inputs.

EM Simulation for Wireless Systems and Antenna Integration on Motor Vehicles

Presentation by Dr. Ahmadreza Jafari, Radio Reception and Antenna Expert, & Phillippe Boutier, Référent RadioFréquence at Renault.

In this presentation, different examples of Renault RF simulations regarding antenna applications such as keyless entry and ignition, AM/FM/DAB radio, radar and V2X are explored. Simulations for keyless entry and ignition are performed using Altair Feko at 125 kHz and 433 MHz. The aim is to define antenna placements to achieve the required hand-free detection zone and remote-control range. Concerning AM/FM/DAB radio, rear-screen and foil antenna radiation patterns are simulated to optimize fine tuning validations. For the radar antenna, impact of the environment around the antenna is explored by simulation.

This presentation also deals with a simple and complete simulation approach for V2X, in which WinProp propagation scenarios are combined with various antenna solutions.

Virtual Drive Tests for ADAS Radar Sensors and Communication Antennas

This webinar shows how Altair WinProp considers the full environment including buildings, cars, street objects in order to get accurate representations of the radio waves impinging on the installed car antennas and the multipath radar channels including reflections, diffractions and scattered contributions. For the efficient analysis the car objects can be also replaced by their corresponding radar cross sections (pre-calculated in Altair Feko). Thus allowing the realistic and fully reproducible evaluations of different options for the antennas and sensors including their integration and configuration.
