An intelligent network connection automobile advancing method based on a special road condition comprises the steps of according to an installation condition of an automobile sensing system, determining detection signal turn-back standard time and a detection signal turn-back standard time interval; determining a horizontal distance between a detection target road section and an automobile; generating corresponding expected driving speeds under different road conditions; utilizing a vehicle sensing system to judge road condition information; and calculating an acceleration of the automobile according to the road condition information, and controlling the automobile so as to adjust an automobile speed to the expected driving speed before entering a fluctuating road condition. According to the method, front road condition information is detected through a radar in front of the automobile, the automobile speed is adjusted in time according to a detection result, a habit of speed reductionin advance of manual driving is met, a problem of automobile speed lag adjustment in the prior art is effectively solved, especially under a short-distance fluctuating and bumpy road condition, a situation of ''speed reduction after passing'' cannot occur, and a driving experience of the intelligent network connection automobile can be greatly improved.
基于特殊路况下的智能网联汽车行进方法,包括:根据车辆感知系统安装情况,确定探测信号折返标准时间和探测信号折返标准时间区间;确定探测目标路段与车辆的水平距离;生成不同路况下对应的期望驾驶速度;利用车辆感知系统,判断路况信息;根据路况信息,计算车辆加速度,控制车辆在进入起伏路况前将车速调节到期望驾驶速度。本方法通过车前雷达探测前方路况信息,根据探测结果及时的进行车速调节,符合人工驾驶提前降速的习惯,有效的避免了现有技术中的车速滞后调节问题,特别是在短距离的起伏颠簸路况下,不会出现“驶过再减速”的情况,能够极大的改善智能网联车辆的驾驶体验。
