Abstract
Forensic experts performing engineering and transport examinations use various methods to determine the speed of vehicles, which are based on calculating the expenditure of kinetic energy of the vehicle on the path of its further movement, which is determined by the work of the forces under the influence of which this movement occurs. In engineering and transport examinations, the capabilities of the Bosch CDR 900 hardware and software complex are widely used to determine the speed before an accident. The software of this complex allows you to set the speed before an accident for a wide range of models of vehicles of the “M1” category. However, this complex does not provide the technical ability to set the speed before an accident for a significant number of vehicles that carry out passenger or freight transportation, namely the categories of vehicles “M1”, “M2”, “M3”, “N1”, “N2”, “N3”. Along with this, studies are being conducted to determine the speed using diagram discs of analog tachographs installed on vehicles of the categories of vehicles “M1”, “M2”, “M3”, “N1”, “N2”, “N3”, which are becoming less common every year. The purpose of the research is to analyze the possibilities of determining the speed of a vehicle at a certain moment in the development of an accident (at the time of a collision, emergency braking or destruction of a vehicle, etc.) using data recorded by first and second generation digital tachographs, which are equipped with vehicles. The methodological basis is the use of instrumental and analytical research methods to determine the speed of a vehicle at certain time intervals and other spatial and dynamic characteristics based on information recorded by control and registration means - tachographs. The scientific novelty lies in various methods of obtaining initial data and their study to determine the speed of vehicles before a road accident. For the first time, the need to introduce into expert practice the method of determining the speed of a vehicle before a road accident, as the main. The conclusions suggest the effective use of a digital tachograph and methods for determining the speed of a vehicle at the time of a road accident for all types of collisions.
