Scenario Variation

Generate scenario variations from seed scenario

Scenario variation is the process of generating multiple variants from a seed scenario that is either manually created or generated from recorded sensor data. You can vary scene parameters, actor parameters, and simulator parameters of a seed scenario and provide your constraints to generate new scenarios. Use these scenario variations for safety assessment of different automated driving applications such as autonomous emergency braking (AEB), lane keep assist (LKA), and adaptive cruise control (ACC).

To generate scenario variations, download the Scenario Variant Generator for Automated Driving Toolbox™ support package from the Add-On Explorer. For more information on downloading add-ons, see Get and Manage Add-Ons.
