Abstract
A motor vehicle related operating signal, such as a torque signal produced by operation of an engine of the motor vehicle, is monitored to produce a frequency signature for the vehicle. The frequency signature is filtered by a fuzzy spectral filter to extract a frequency membership for the vehicle which is utilized to generate characteristic signals representative of the vehicle. Signals representative of vehicle inertia (J), vehicle horsepower (HP) and relative vehicle temperature (RVT) are extracted by a radial basis function (RBF) neural network. These characteristic signals are then used to control the vehicle directly via a powertrain control module (PCM) or via a robot driver for vehicle test purposes. For robot control, an anticipated throttle lag and an anticipated brake lag are generated and used to more accurately and repeatedly control the robot to simulate a human driver in following acceleration curves for vehicle testing purposes.
