A comprehensive development methodology for testing and evaluating algorithms for a vehicle suspension control system

Introduction. Full-scale tests remain the most important quality indicator of the developed design solutions. At the same time, high-performance simulation computational systems are becoming more and more relevant, which can significantly reduce field tests of newly developed prototypes of vehicles. The task of building a transparent connection between full-scale and virtual tests is always relevant for a high-quality and effective study of the tested object behavior. This article touches on topical engineering issues in the development of complex assessment techniques for controlled vehicle systems.

The purpose of the study was to solve the problem of the cumulative assessment of various control algorithms for the suspension system for solving the integration problem of comparing control algorithms, regardless of their implementation. The results of solving this problem are recommendations for improving the vehicle movement algorithms in various conditions and modes.

Methodology and research methods. The article provides a rationale and general description of a comprehensive methodology for a controlled suspension system for a vehicle chassis, a sequence of planning experiments and the analysis of the results achieved. The sequence of construction of the estimated “conflict diagram” (Carpet plot) from the test data is given. The analysis of the results is presented and considered in the diagram as an example.

Scientific novelty and results. The approaches outlined in the article were used by the authors at the initial stages of the controlled chassis suspension system development, which made it possible to improve the quality and efficiency of the achieved result in the shortest possible time. The developed and approved comprehensive test method and methods for assessing the controlled chassis suspension system is a scientific novelty, since such methods and approaches have not been used before.

Practical signifi cance. The developed complex test methodology and assessment methods are used at FSUE “NAMI” at the initial stages of designing controlled chassis suspension systems.
