Parametric Synthesis of a Robust Automatic Vehicle Course Stability System

Relevance of the research. One of the main safety features preventing accidents in modern vehicles is the automatic course stability system, which is activated during emergency braking under complex driving conditions. A wide range of external disturbances and rapid changes in the vehicle motion parameters during emergency braking require the course stability system to have properties of invariance to external disturbances and robustness to rapid changes in vehicle motion parameters. The object of the research is dynamic processes in a closed-loop automatic vehicle course stability system . The subject of the research is the selection of optimal values of the varied parameters of the electronic unit of the vehicle course stability system, which ensure high dynamic accuracy of the system and its robustness to rapid changes in the current vehicle speed. Results. An algorithm is proposed for selecting the optimal values of the variable parameters of the electronic control unit of the automatic vehicle course stability system with the simultaneous selection of the weight coefficients of the additive integral quadratic functional, which is a quantitative assessment of the system's accuracy and its robustness to rapid changes in vehicle speed during emergency braking.
