The invention relates to the technical field of vehicle automatic driving, and discloses a cruise vehicle speed control method, a cruise vehicle speed control system and a vehicle. The cruise vehiclespeed control method comprises the following steps: acquiring a set cruise vehicle speed value, a cruise vehicle speed maximum fluctuation value and a maximum vehicle speed limit value; according to the obtained set cruise vehicle speed value, the cruise vehicle speed maximum fluctuation value and the highest vehicle speed limit value, obtaining a corrected cruise vehicle speed value according toa set rule, and the sum of the corrected cruise vehicle speed value and the cruise vehicle speed maximum fluctuation value is smaller than or equal to the highest vehicle speed limit value; and outputting the corrected cruise vehicle speed value to a cruise vehicle speed control module. By means of the setting mode, the situation that the cruise vehicle speed exceeds the maximum vehicle speed limit value due to the fact that the set value is too large or under the influence of the fluctuation value is avoided, and therefore the situation that the fuel injection amount is reduced to zero instantly is effectively prevented, the phenomenon that the vehicle speed is increased or decreased circularly is effectively avoided, the jerking feeling of the vehicle is greatly reduced, and the drivingcomfort is improved.

    本发明涉及车辆自动驾驶技术领域,公开了一种巡航车速控制方法、巡航车速控制系统及车辆,该巡航车速控制方法包括:获取设定的巡航车速值、巡航车速最大波动值以及最高车速限制值;根据获取的设定的巡航车速值、巡航车速最大波动值以及最高车速限制值,按照设定规则得到修正后的巡航车速值,修正后的巡航车速值与巡航车速最大波动值之和小于或等于最高车速限制值;将修正后的巡航车速值输出至巡航车速控制模块。这种设置方式,不会出现巡航车速由于设定值过大或者在波动值的影响下超出最高车速限制值的情况,从而有效防止了喷油量瞬间降低至0的情况,从而有效避免了车速循环加减的现象,大大降低了车辆的顿挫感,提高了驾驶舒适性。
