[0002] The Rollover Prevention System (RPS) is a safety system used to improve the stability of a vehicle during high-speed turns or emergency avoidance. This system is particularly suitable for commercial vehicles, buses and vehicles with a high center of gravity, because these vehicles are more prone to rollover accidents in certain situations. The rollover prevention system monitors the vehicle status in real time through a variety of sensors and actuators, and takes corresponding control measures to prevent or reduce the risk of rollover. However, the current automobile turning rollover prevention system usually uses the method of braking the wheels to reduce the risk of rollover. When the turning speed is too fast, the car body will tilt and cause rollover. Braking the wheels can only slow down the car body. When the car body has tilted, it cannot reduce the risk of rollover, which is inconvenient to use. Summary of the invention
