Failures of systems and mechanisms of the internal combustion engine are among the first among the total number of failures of tractors and cars. To determine them, a significant number of methods and means of determining the technical condition (diagnosis) are used. Functional-cost analysis is a heuristic method aimed at identifying the possibilities of reducing the cost and increasing the quality of the object, which is considered as a system with an orientation to a functional approach at all stages of its life cycle.
This scientific article presents a functional and cost analysis of the anti-lock braking system of cars. A functional model of this system was developed and its functions were classified.
The classification of the functions of the functional model of the anti-lock braking system of cars is also presented. The utility coefficients of this system are actually determined by constructing a matrix of advantages according to the known methodology.
The generalizing cost criterion in the design of technical and production systems takes into account costs at all stages of the system's life cycle. To estimate these costs, a matrix of the anti-lock braking system of cars was created, with which the cost factors are calculated.
Constructed function utility diagrams, function location, function-cost and cost diagrams allowed to use the functions of the anti-lock braking system of cars, which have a positive function-cost indicator and the highest rating among the presented functions. Such an operation or functions, marked by the highest functional value indicator and rank, are key to the further development of the system or the achievement of the goal of the analysis.
