Heavy-duty vehicles, such as trucks and buses, play a crucial role in transportation and commerce, facilitating the movement of goods and people across vast distances. However, these vehicles are also susceptible to rollover accidents, which can have devastating consequences in terms of loss of life, property damage, and economic impact. According to statistics from the National Highway Traffic Safety Administration (NHTSA), rollover accidents involving heavy-duty vehicles are among the most severe and deadliest types of crashes on our roads.. In this paper, we propose a Real-Time Rollover Safety System designed specifically for heavy-duty vehicles. Our system leverages advanced technologies, including the STM32F407 microcontroller, servo valve, and hydraulic system, to effectively monitor and control the vehicle's tilt angle in real-time.
