Development and Modeling of a Device to Improve Safety Control of Freight Transport With Trailers

Ensuring vehicle safety is a major issue for the Ukrainian transport industry, the level of which is influenced by numerous factors, including: road network congestion; road network expansion; road quality and markings; increasing vehicle fleet and population growth; low discipline and culture of road users; insufficient driver qualifications; technical condition of vehicles and their improper operation, etc. Of particular concern are frequent and serious accidents involving large-sized freight transport. Active safety systems reduce the risk of dangerous situations on the road and contribute to more confident vehicle control. They help the driver effectively brake, accelerate with optimal intensity, and perform maneuvers with minimal effort. Over time, any equipment can fail, which can lead to downtime, delays in cargo delivery, and in some cases, to emergencies. The trailer braking system is constantly being improved, which allows for better control during operation. While driving, the driver constantly assesses the road situation, and the accuracy, reliability and speed of vehicle control largely depend on his personal skills and professional qualities. The developed device can be used: for external control of the rotation of the trailer wheels from the driver's cabin, which is visible in the rear-view mirror; to help the driver better feel the dimensions of the trailer (due to which reversing becomes easier); as a diagnostic device (when braking, it is possible to determine which wheels are locked, whether they are in satisfactory condition). Simple, cost-effective. In most cases, it is used in the winter, not connected to other electrical systems of the car.
