This paper presents a fuzzy logic controller for performing autonomous vehicle following which is defined as a vehicle controlling its own steering and speed while following a lead vehicle. This controller functions by first converting the range and heading angle observation into fuzzy variables, by executing fuzzy rules generated by a self-organizing neural network, and then by defuzzifying the resultant fuzzy steering-wheel angle and speed variables. In contrast to a model-based controller, the developed fuzzy controller constitutes a model-free approach. A noise analysis has been carried out to evaluate the performance of such a controller in the presence of observation noises in terms of the lateral and longitudinal deviations from the path of the lead vehicle. The performance of this controller is compared to that of a previously developed model-free neural network controller.
