The paper focuses on the sideslip problem in the small overlap crash test in the vehicle structural safety field. A two-degree-of-freedom first-order dynamic model of the vehicle is established, based on which a segmented sideslip motion planning method is proposed, and a vehicle sideslip motion planning software for small-overlap crash conditions is developed. The experimental results show that the proposed planning method enhances the vehicle's lateral displacement by 30%, thereby facilitating successful sideslip. This elevates the vehicle structural rating from Acceptable (A) to Good (G) and significantly improves the safety performance in the small-overlap ceashes.

为解决车辆小偏置碰撞工况侧滑运动问题,建立了整车两自由度一阶运动模型,据此提出整车分段侧滑运动规划方法,并开发了小偏置碰撞工况整车侧滑运动规划软件。试验结果表明,所提出的规划方法使车辆侧滑量增大了30%,成功实现侧滑,车辆结构评级由良好(A)提升至优秀(G),提升了小偏置碰撞结构安全性能。

为解决车辆小偏置碰撞工况侧滑运动问题,建立了整车两自由度一阶运动模型,据此提出整车分段侧滑运动规划方法,并开发了小偏置碰撞工况整车侧滑运动规划软件。试验结果表明,所提出的规划方法使车辆侧滑量增大了30%,成功实现侧滑,车辆结构评级由良好(A)提升至优秀(G),提升了小偏置碰撞结构安全性能。

The paper focuses on the sideslip problem in the small overlap crash test in the vehicle structural safety field. A two-degree-of-freedom first-order dynamic model of the vehicle is established, based on which a segmented sideslip motion planning method is proposed, and a vehicle sideslip motion planning software for small-overlap crash conditions is developed. The experimental results show that the proposed planning method enhances the vehicle's lateral displacement by 30%, thereby facilitating successful sideslip. This elevates the vehicle structural rating from Acceptable (A) to Good (G) and significantly improves the safety performance in the small-overlap ceashes.
