Automatic driver system
First Claim
1. An automatic driving means for operating a vehicle having an accelerator pedal for controlling the throttle, the vehicle being mounted on traction rollers of a chassis dynamometer, said automatic driving means including:
- accelerator pedal actuator means for moving the accelerator pedal;
sensing means for sensing vehicle speed, accelerator pedal position and said accelerator pedal actuator means velocity; and
accelerator pedal control means for driving said accelerator pedal actuator means and being coupled to said sensing means for generating a triple loop accelerator pedal control signal using vehicle speed, accelerator pedal position and pedal actuator motor velocity feedbacks, so as to reduce throttle fluctuations.

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.
