A neural network was applied to the estimation of vehicle weight for improved power-train control. The change in acceleration response according to vehicle weight was measured and utilized for the estimation. The measured acceleration response was input into the neural network which then output the estimated vehicle weight. The accuracy of the estimation was evaluated by computer simulation and field experiments. Using the throttle valve opening and the time signals of vehicle speed and acceleration, the weight estimation error was reduced to 20 kg, within an acceptable amount for the vehicle control.
