“…For non-tilting ground vehicles, the tyre generates the lateral forces predominantly through the tyre slip angle. As the tyre sideslip angle increases to a certain value, its relationship with the tyre cornering force becomes non-linear due to the saturation of the cornering force [7]. For small tyre slip angles, the lateral force is generally proportional to the slip angle, but as the tyre slip angle increases, the tyre is unable to generate a proportional increase in the lateral force.…”

In the simulation, regenerative braking is increases to meet the increasing direct yaw moment, applied with the EHB and the braking force by the magnitude of the direct yaw moment decreases the EHB module is applied only for the right side since the contribution from the lateral force decreases wheels in order to generate the required direct yaw due to the tyre friction circle characteristic [3,7]. moment.…”

Vehicle stability control for a four-wheel drive (4WD) hybrid electric vehicle is investigated using the regenerative braking of the rear motor and electrohydraulic brake (EHB). A fuzzy-rule-based control algorithm is proposed, which generates the direct yaw moment to compensate for the errors of the sideslip angle and yaw rate. Performance of the stability control logic is evaluated for J-turn and single-lane change. It is found from the simulation results that the regenerative braking of the rear motor is able to provide improved stability compared with the vehicle performance without any control. It is found that better performance can be achieved by applying the regenerative braking plus the EHB control. In addition, the optimal distribution ratio of the EHB force is presented to minimize the EHB power consumption. The simulation results show that the required torque level by the optimal EHB distribution ratio control is much lower than that of the fixed distribution ratio, while providing almost the same control performance. It is expected that the vehicle stability control algorithm suggested in this study is able to offer improved vehicle stability.vehicle safety enhancement systems, such as the offset yaw moment generation using the brake force Republic of Korea. email: hskim@me.skku.ac.kr D00605
