Improving the reliability elements of the “driver-machine-road conditions” system with the operation of the articulated vehicles

Abstract

The approach to improving the reliability of the "driver-vehicle-road conditions" system in the operation of articulated vehicles is justified, which improves the driver's interaction with the system of ensuring dynamic stability during driving. The method of assessing the reliability of the driver of articulated wheeled vehicle has been developed, using the Dynamic Stability Criterion (DSC) as a diagnostic parameter. The parameter is evaluated using a mobile registration and measurement complex (MRMC). The justification of the zones of acceptable and unacceptable values of the criterion allows to determine the degree of influence of the driver on the occurrence of accidents related to rollover. Based on the fact that drivers' attitude and motivation to perform transport operations with compliance with safety requirements may be different, the main effect for improving reliability in the application of the developed approach can be obtained by comparing the results of objective control of the process of movement with the help of MRMC for different drivers in different road conditions. The "green zone" of the current position stability parameters is set. The driver during driving, taking into account his own capabilities, road conditions, fuel economy and other parameters, chooses a safe, in his opinion, mode of movement. MRMC in the process of movement, demonstrating in real time the current value of the criterion of dynamic stability, tells the driver about the correctness of the chosen mode. In the case of high growth intensity of the DSC, for example, at a significant speed of movement, which does not meet the road conditions, the driver does not have time to intervene in the process of the vehicle stabilization.
Therefore, MRMC will be triggered to ensure sustainability. If the growth rate of the DSC is not critical,
then the driver has a reserve of time to stabilize the vehicle without connecting the system. If the growth
intensity of the DSC is low, the driver is in full control of the process of movement, the help of MRMC in the
marked case is not needed.
Based on the research and analysis of existing experience, additional recommendations have been developed to improve the safety of the use of articulated wheeled vehicles, taking into account their design features.
The study results can be used in the operation of articulated wheeled vehicles.
