Abstract: A test method includes deriving road grade information or wind load information from test schedule torque outputs generated by a dynamometer operatively arranged with a first vehicle, and controlling an accelerator pedal, an accelerator pedal signal, a fuel injector, a manifold pressure, a motor controller, or a throttle valve associated with the first or a second vehicle according to a speed schedule such that the dynamometer, or another dynamometer, programmed with the road grade information or wind load information and operatively arranged with the first or second vehicle applies a load to the first or second vehicle that reflects the road grade information or wind load information.
