Abstract
In this article, a mathematical model was developed to influence the intensity of the steering wheel turn by the driver on the vehicle's stability. Comparison of the developed mathematical model with the experiment results made it possible to establish their adequacy. The effect of the three conditional drivers on the intensity of the steering wheel was examined. When performing the 'J-turn' maneuver, comparing the indices of the 1st, 2nd and 3rd conditional drivers, their proximity to the requirements of the standard was established. It was found that the indices of the second conditional driver are closest to the standard requirements. When performing the 'Single Lane Change' maneuver by the first conventional driver, the standard deviation value from the specified trajectory was 0.102, and the correlation index was 0.88.
Highlights
Road traffic accidents occur mainly due to insufficient professional skills and work experience, improper maneuvering, and inattention to the speed limit
The purpose of the experimental research was to determine the transient and steady-state characteristics of the vehicle on the steering action and to obtain the necessary characteristics to test the adequacy of the mathematical model
The 'J-turn' and 'Single Lane Change' tests were selected to determine the transient response of the vehicle to driver input
Summary
Road traffic accidents occur mainly due to insufficient professional skills and work experience, improper maneuvering, and inattention to the speed limit. According to the results of the studies [4], it was determined that more than 50% of accidents as a result of car lane-change were committed due to non-compliance with the speed limit, improper maneuvering. Equations of motion have the form of a system of higher-order equations, which pose some difficulties in solving them. The reason for this lies in need to determine the parameters of the vehicle units and parts based on the results of experimental studies.
