Methods for On-line Monitoring Rollover Stability of Large Bus

摘要

In order to improve the operation safety of large bus, an on-line monitoring method of rollover threshold based on the loads of tire was proposed. Analyzed the performance of the vehicle anti-rollover, the rollover threshold expression was given, and rollover threshold only related to centroid position. According to vehicle static and brake equilibrium equation, the relational model between the tire load and centroid position was built. The trucksim dynamic simulation software was used to verify the monitoring algorithm, and the maximum relative error of the estimate rollover threshold is 5.36%.
