Abstract

The use of Neural Networks (NN) is necessary to bring the behavior of Intelligent Autonomous Vehicles (IAV) near the human one in recognition,learning, decision-making, and action. First, current navigation approachesbased on NN are discussed. Indeed, these current approaches remedyinsufficiencies of classical approaches related to real-time,autonomy, and intelligence. Second, a neural navigation approach essentially based on patternclassification to acquire target localization and obstacle avoidancebehaviors is suggested. This approach must provide vehicles with capability,after supervised Gradient Backpropagation learning, torecognize both six (06) target location and thirty (30) obstacle avoidancesituations using NN1 and NN2 Classifiers, respectively.Afterwards, the decision-making and action consist of two associationstages, carried out by reinforcement Trial and Error learning, and their coordination using a NN3. Then, NN3allows to decide among five (05) actions (move towards 30°, move towards60°, move towards 90°, move towards 120°, and move towards150°). Third, simulation results which display the ability of theneural approach to provide IAV with capability tointelligently navigate in partially structured environments are presented.Finally, a discussion dealing with the suggested approach and how itrelates to some other works is given.
