The paper deals with the design of the fuzzy logic - based comparator that compares the data of traction vehicle velocity in target braking process and its optimisation using the ANFIS method. Some failures of the system in Matlab - Simulink environment have been simulated. The result is the analysis of ailures consequences from the point of system safety.text/htmlapplication/pdfjournal article
