ABSTRACT:
A fuzzy logic based navigation module for use on a semi-autonomous vehicle computes the safety of moving from predefined local regions to adjacent local regions for the purpose of planning a safe path for the vehicle to take to reach its intended destination. Image understanding software provides the input to the system in the form of values for linguistic variables for each local region which impact the safe movement of the vehicle. Using a five level hierarchial rule base structure, the fuzzy inference process computes intermediate and final safety values which are affected not only by local conditions but also by nearby conditions in order to allow a minimum clearance for the vehicle.
