ABSTRACT:
An automatic driving system for operating a vehicle on traction rollers of a chassis dynamometer includes an accelerator pedal actuator for moving the accelerator pedal. A sensing means senses vehicle speed, accelerator pedal position and accelerator pedal actuator velocity. Accelerator pedal control means drives the accelerator pedal actuator and is coupled to the sensing means for generating a triple loop accelerator pedal control signal using vehicle speed, accelerator pedal position and actuator motor velocity feedback to reduce throttle fluctuations.
