Portable Automated Driver for Road Vehicle Dynamics Testing

Abstract

An automated test driver (ATD) has been developed which is capable of executing dynamic test maneuvers with accuracy and repeatability beyond the ability of a human driver. This system enables any production car or light truck to follow a user-defined path or to perform specific steering sequences with excellent repeatability. Combined with an automated brake and throttle controller, capable of matching a desired velocity profile as well as providing specific test inputs with acceleration or other feedback, this system provides a powerful tool to improve vehicle dynamics testing.
