Simulation

Definition

Simulation refers to the process of creating a virtual model that replicates the behavior of a real-world system or process. In the context of autonomous vehicles, simulations allow engineers to test and refine control algorithms, including lateral control, without the risks associated with real-world testing. By using simulation, designers can analyze vehicle responses to various driving scenarios, enhance safety features, and improve overall performance.
