Systems and methods for generating scenarios for AV simulation using parametric modeling

A computing system for parametric simulation for autonomous vehicles comprising:

• one or more processors;
• and
• one or more tangible, non-transitory, computer readable media that collectively store instructions that when executed by the one or more processors cause the computing system to perform operations comprising:
• obtaining scenario component data associated with a plurality of scenario components;
• obtaining data identifying a plurality of parameters, each parameter associated with a particular scenario component;
• determining values for a first set of parameters in the plurality of parameters, wherein determining values for a first set of parameters in the plurality of parameters further comprises:
• for a particular parameter in the first set of parameters:
• determining a maximum value;
• and
• determining a minimum value;
• determining one or more parameter relationships, such that values associated with a second set of parameters in the plurality of parameters are determined, at least in part, based on the values associated with one or more parameters in the first set of parameters;
• performing a simulation of a scenario based, at least in part, on the values associated with the first set of the parameters and the one or more parameter relationships;
• determining based on one or more criteria whether a simulated autonomous vehicle has successfully completed the scenario during the simulation;
• and
• updating, by the computing system, a control system of one or more autonomous vehicles based on whether the simulated autonomous vehicle successfully completed the scenario.
