本文首先分析了回旋曲线用作缓和曲线所引起的诗多弊端;然后提出了一种较为合理的方向盘操作特性。并在匀速行驶的条件下推导出一种曲率变化连续的缓和曲线,以替代回旋曲线,进一步提高行车的安全性和舒适感。 This paper firstly analyzes the drawbacks of the poem caused by the use of the curl curve as the easing curve, and then proposes a more reasonable operation characteristic of the steering wheel. And at a constant speed under the conditions derived a curve of curvature of the continuous relaxation curve to replace the clothoid curve to further improve driving safety and comfort.
