Abstract
A test method for a vehicle powertrain includes, during a first test in which dynamic engine torque from a powertrain drives a vehicle on a road, recording throttle position or accelerator pedal position to define a throttle schedule, and recording engine speed to define an engine speed schedule. The test method further includes, during a second test of a vehicle engine, controlling a dynamometer and the vehicle engine according to the engine speed schedule and throttle schedule to reproduce the dynamic engine torque.
