"These tools also give us a real competitive advantage to demonstrate our high-quality, durable automotive illumination solutions to our customers through lifelike and reliable pictures and videos."

Ansys' optical and simulation solutions empower Weldex Corporation to render our engineering innovations into visual material," said William Jung, CEO, Weldex Corporation. "We are able to import optical simulation results of headlamps from Ansys SPEOS to Ansys AVxcelerate Headlamp and use scenarios created in Ansys VRXPERIENCE Driving Simulator powered by SCANeR™ to create movies of driving vehicles equipped with our products' virtual prototypes. We use the results to facilitate post-processing and data visualization for lamp certification, replacing costly and difficult night tests.

New APIs for Sensor Simulation

The new APIs to control the sensor simulation and access raw sensor output will increase productivity through the support of your specific process and engineering tools.

Streamline Intelligent Lighting Systems Development Through Virtual Night Tests

The unique features of real-time optical simulation allow headlight designers to perform virtual night tests and assess headlamp performance without going to the test track.

Ansys VRXPERIENCE Headlamp extends testing for intelligent lighting, such as AFS, ADB, matrix and pixel beam, and control law models to assess IIHS ratings. Additionally, perform early driver-in-the-loop testing, increasing the final product quality and strongly reducing the risk of finding issues late in the development process.

 

Key Capabilities

The physically accurate results produced by the AVxcelerate Headlamp real-time simulation allow you to perform accurate reviews and make reliable decisions before the physical prototyping phase. 

  • Headlamp Simulation
  • Driving Scenarios
  • Virtual Measurement
  • Intelligent Lighting Systems
  • Discomfort Glare Assessment
  • IIHS Virtual Assessment

The real-time, physics-based solution allows you to simulate virtual prototypes of headlamps to detect, analyze and compare any defects in beam patterns, including chromatic aberrations.

Use the pixel beam or matrix beam testing scenarios for several cars at once, allowing you to generate scenarios such as oncoming and preceding vehicles, crossroads, takeover maneuver, etc., in any environment, from urban areas to countryside. Include test drivers within the decision loop thanks to the driver-in-the-loop capabilities of AVxcelerate. 

Visualization in false colors facilitates the comparisons between different behaviors and light sources — Halogen, Xenon or LED. Measurement grids ease the assessment of homogeneity of light distribution and the aiming wall allows you to check the conformity of the cut-off according to regional regulation.

The solution offers a real-time pixel beam simulation and control mechanism capable of managing pixel-level beam behavior (such as DMD or microLED systems for example). Efficiently develop, iterate and test your intelligent lighting system control software, up to hardware-in-the-loop simulation with camera sensor injection.

With AVxcelerate's glare-free high beam feature, you can measure the discomfort of the glare generated by the other vehicle headlamp from a driver’s perspective, including a visual gauge to objectively measure the discomfort. A corresponding visual effect is added to the rendering view to graphically show the glare impact. Measurements provide a quantified, detailed analysis on several lighting configurations and scenarios for easy comparison.

The vehicle under test automatically drives along a normed trajectory where virtual illuminance sensors are positioned according to the standards. AVxcelerate Headlamp considers vehicle dynamics and intelligent lighting control laws. An automated batch test mode allows you to evaluate several headlamp configurations in a row, generating a detailed report including the rating and detection thresholds.
