Abstract: With the rapid development of the transportation industry, the rollover stability of commercial trucks is receiving increasing attention. This paper takes the yaw rate and lateral velocity variation of commercial trucks as control variables, combines the TTR rollover warning theory and the rollover vehicle model of commercial trucks to design the warning strategy, predicts the vehicle lateral acceleration through the Kalman filter estimator, and then calculates the rollover threshold value, and then obtains the optimal additional yaw moment through the linear quadratic regulator regulator according to the vehicle linear model. Using a single wheel control strategy, perform anti roll control on the established model. The reliability of the strategy is simulated and tested through extreme operating conditions to verify the effectiveness of the control strategy adopted in this paper.
