Ansys AVxcelerate realistic sensor testing and validation enables you to test your autonomous vehicles, ADAS and sensors faster than with physical prototypes.
Virtually Experiment with Your Sensors to Meet Physical Needs
To reduce the need for costly physical prototypes while speeding the design process, the Ansys AVxcelerate Sensors solution offers the opportunity to virtually experience sensors to test and analyze their performance. In the virtual world, use realistic driving scenarios to investigate radar, lidar and camera sensors perception in a Mil Sil or Hil context.
Discover high-fidelity physics-based sensor simulation with ground truth information for autonomous vehicles. Enable the use of multiple sensor simulations amidst realistic driving scenarios to ensure the physical prototype meets expectations.
Integrated simulation scenarios speed and improve the ability to confirm safety features across vehicle creation, including autonomous vehicles.
Autonomous driving systems rely upon sensors and embedded software for localization, perception, motion planning and execution. They can only be released to the public after developers have demonstrated their ability to achieve 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 until now to validate safety-critical software, such as the kind that control 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 serves the need to make verification and validation of the operation of autonomous vehicles a practical effort.

Benefit from powerful ray-tracing capabilities to recreate sensor behavior and easily retrieve sensor outputs through a dedicated interface.
To test sensors in scenarios, add several cars to create complex situations, such as following a car and monitoring the path of a crossing car simultaneously. Each vehicle in a scenario can be either static or automatic, enabling evaluation at a specific point of interest or along a predefined trajectory. Sensor simulation follows ego-vehicle dynamic motion.
Sensor data output, such as lightning strike hit points, material properties, etc., and vehicle parameter input or output, such as position, orientation, speed, and steering wheel, are all available. Thanks to the consistent combination of data from multiple sensors, the simulation enables you to validate the model of a smart sensor’s behavior or its fusion algorithms. Deterministic and real-time modes are both supported.
Software allows you to simulate the actual camera model in edge case driving situations. It simulates all components of a camera, such as the lens system, imager and pre-processor. For automotive front-facing cameras, the windshield can also be considered in simulation. Consider the optical and spectral properties of the environment in visible range, along with the optical properties of the lens system and optoelectronic properties of the imager. With the addition of plugins, the simulation can manage dynamic adaption. Camera simulation creates raw images, which are used to test and validate perception algorithms either as models-in-the-loop, software-in-the-loop or hardware-in-the-loop.
You will benefit from powerful ray-tracing capabilities to recreate sensor behavior and be able to easily retrieve sensor results through a dedicated interface. IR emitter world model IR properties (is this “The IR emitter will model IR properties?” and receiver electronics are considered in the simulation which can output from raw signals – waveforms – to point clouds. This solution provides a unique way to collect virtual sensor information during real-time drives and use the information to develop autopilot code.
VRXPERIENCE’s GPU Radar feature provides the capability to perform full physics-based radar scenario simulations in real time at frame rates greater than 30 frames per second.
