“…Assuming a linear dependence of the braking forces on the drive pressure, these criteria are convenient for estimating the unevenness of the braking forces during bench testing since they depend only on the ratio of the braking forces and not on their absolute value. However, this is also the reason why these criteria do not accurately characterize the maximum value of the turning moment from the non-uniformity of the braking forces, on which the stability of the car ultimately depends [8][9][10]. From Fig.…”

It is justified to evaluate the car's stability during braking, not only from the ratio of braking forces but also from their absolute value. Because the ratios of the braking forces do not accurately characterize the maximum value of the turning moment from the unevenness of the braking forces, on which ¬the stability of the car ultimately depends. Depending on the braking system's characteristics, emergency braking can occur either without wheel blocking or with a certain combination of blocked wheels; due to significant differences like braking, the permissible unevenness for the corresponding type of braking should be determined according to different criteria. An algorithm for determining the permissible unevenness of the braking forces on the wheels of the front axle of the car when braking with locked rear wheels and when braking without blocking the wheels has been compiled.

“…Figure 1: Distribution of the main types of vehicles in the Russian Federation It is known, that the design and construction of roadway widenings, crossings and junctions, and subsequently, the organization of traffic is impossible without taking into account the geometric data of the design vehicle, which is taken on the basis of the analysis of the traffic flow composition [6][7][8][9][10]. In Russia, for calculation of mandatory control, constant reduction coefficients of the design vehicle are used, developed based on the geometric characteristics of the first domestic cars, such as: Moskvich 407, Microlitre M-21 "Volga", M-20 "Pobeda", ZIL-11.…”

Over the past decades, the automotive market has been growing and developing rapidly. Vehicles are constantly modified: their geometric parameters (length, width, height, etc.) and dynamic parameters (power, acceleration speed, etc.) change. For the design and construction of the roadway, as well as subsequent calculations in the field of traffic management (flow saturation, mandatory control, etc.) in accordance with the regulatory documentation, geometric and dynamic parameters of the design vehicle are used, the parameters of which are determined on the basis of Soviet cars of the 80s. As a result of vehicles changes and modifications, it is necessary to update and perform additional calculations to determine the parameters of an improved design - calibrated vehicle. The main purpose of the study is to determine the parameters of the design – calibrated vehicle for performing calculations in the field of construction and traffic management. In the course of the research presented in this article, the analysis of statistical data regarding the best-selling light vehicles, as well as the variability of the geometric parameters of vehicles were determined. Based on all the completed tasks, the result of the work is determination of the design - calibrated vehicle for Arctic zone of the Russian Federation, which will be subsequently used for the design and construction of the roadway and calculations in the field of traffic management.

“…As with batteries, estimation of the current state and parameters is performed on powertrains [45] and supercapacitors [46]. In addition, however, we also see an application of digital twins towards diagnosing the internal faults of an automated brake system [38], [39]. Once humans are introduced as an entity to be twinned, the focus appears to shift towards predicting intentions.…”

In recent years, digital twins have been proposed and implemented in various fields with potential applications ranging from prototyping to maintenance. Going forward, they are to enable numerous efficient and sustainable technologies, among them autonomous cars. However, despite a large body of research in many fields, academics have yet to agree on what exactly a digital twin is -and as a result, what its capabilities and limitations might be. To further our understanding, we explore the capabilities of digital twins concerning diagnosis in the field of transportation. We conduct a systematic mapping study including digital twins of vehicles and their components, as well as transportation infrastructure. We discovered that few papers on digital twins describe any diagnostic process. Furthermore, most existing approaches appear limited to system monitoring or fault detection. These findings suggest that we need more research for diagnostic reasoning utilizing digital twins.
