Problem. Currently, the problem of optimal control of the road machines is one of the most pressing tasks. Consequently, there is a significant need for on-board multifunctional measuring systems. Along with this, today measuring systems are mainly used only to provide control of power units. It is still relevant to determine the spatial position of the working bodies of the road machine in order to optimize their movement when performing working technological processes. Goal. The goal is to investigate the measurements of linear movement of road machine design elements when complexing ultrasonic and optical sensors of linear movements. Methodo-logy. The analytical and experimental research methods for the development and application of onboard measuring systems have been used. When complex the method of sensors combined into one system, the methods of system analysis were used. Results. Functional features of application of optical and ultrasonic gauges for measurements of linear moving elements of a design of the road machines are revealed. Principles of measurements of linear moving are investigated at complex use of gauges in a uniform measuring system. Originality. In order to improve the accuracy of technological processes and optimal control of the road machine, it is proposed to measure the linear movement of structural elements both relative to each other and relative to the earth's surface. The combined use of ultrasonic and optical methods will significantly reduce measurement errors. Practical value. The use of the proposed method for measuring the relative position of the structural elements of a road machine design will make it possible to perform high-quality technological processes at any time of the year or day, regardless of the current natural and weather conditions.
