ABSTRACT

In order to address the high level of danger posed by vehicles experiencing tire blowouts, this article modifies the tire parameters of the vehicle model in Carsim. By simulating a high-speed blowout scenario, the non-blowout tire cylinder braking pressure is controlled using non-linear control in MATLAB/Simulink. This allows for a comparison of the vehicle's motion before and after a blowout. By adjusting the input curve of hydraulic braking pressure multiple times, it was found that introducing a sixth-order control function effectively stabilizes the vehicle after a blowout, preventing it from deviating from the lane. This is mainly manifested by a stable yaw angular velocity of -1deg/s and a deviation from the lane of ±1.5m. These findings have significant research and engineering value in terms of stability control for vehicles after a blowout.
