| Abstract: | In order to improve the anti-rollover capability,by analyzing the internal relationship between lateral-load transfer rate（LTR） and the vehicle dynamic parameters,a new refine dynamic model for describing the vehicular differential-braking condition was presented based on the 4-DOF vehicle model and the LTR.By this model,how the braking force affected the anti-rollover performance and the vehicle movement was investigated.The whole research reinforces the differential-braking control theory for anti-rollover.The simulation results validate the effectiveness of dynamic model. |
