Abstract
A method and apparatus for controlling a robot to simulate driving of a motor vehicle while the vehicle is actually on a chassis dynamometer includes provision for quickly, automatically, and accurately determining an accelerator gain factor to be used by the robot in actuating the accelerator of the motor vehicle to achieve predetermined vehicle speeds and accelerations. As a result, the simulated driving of the motor vehicle can be achieved so that the vehicle may be tested according to a predetermined travel pattern. To determine the accelerator gain, a proportional gain is determined on the basis of differences in incremental accelerator openings and resulting accelerations's while the motor vehicle is in a selected transmission gear. A product of the gain multiplied by a coefficient based on the various transmission ratios available is used as the accelerator gain dependent upon the particular transmission ratio selected during a test sequence.
