Cars are a dynamic system with lots of parts, units, systems and units. One of the units responsible for the safety of the car is steering. Existing methods and means of diagnosis of steering can be characterized by low efficiency. For various reasons, both declarative and real existing (supported equipment) methods usually have low accuracy and inability to localize malfunctions. Currently, in most cases, the roller control system faults are found on external grounds. It is possible to improve the quality of the process of diagnosis of steering control, including the creation of new mathematical models of their functioning.
Existing methods and means of diagnosis of steering as an integral element of road transport are analyzed. It is established that existing methods and means of diagnosis of steering do not fully allow to determine their current technical condition, which requires the development of mathematical models of their units and parts as an object of diagnosis.
Toyota Camry's cars are selected as a diagnosis object. The analysis of the design of the steering of the car "Toyota Camry" as an object of diagnosis is presented. Replacing real technical devices by their idealized models allows you to widely use different mathematical methods. The mathematical model is proposed in general, which is a system of functional dependencies between each diagnostic signal and structural parameters. Toyota Camry cars are drawn up for the steering car control, which includes a list of malfunctions and signs of malfunctions.
The proposed mathematical model of diagnosing the steering of the car "Toyota Camry" will reveal the malfunctions of its units and parts, depending on their features with the help of an artificial neural network.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production.
During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured.
Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
The journal consistently adheres to the principles of open science. All published materials are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), ensuring open access to research results provided proper attribution to the authors and the original publication is maintained.
At present, Technology, energy, agriculture transport AIC is an authoritative professional scientific journal (Category B), providing a platform for the publication of fundamental and applied research results, promoting the integration of education, science, and industry, and contributing to the advancement of engineering and technological support of the agro-industrial complex of Ukraine.
