The invention provides a vehicle speed accurate control method and system of an automatic driving vehicle. The method comprises the following steps: acquiring a target vehicle speed and a real-time vehicle speed, and calculating a deviation value according to the target vehicle speed and the real-time vehicle speed; when the deviation value is larger than a threshold value, the historical vehicle speed in a first period is obtained; calculating the vehicle speed control quantity of the next moment according to the historical vehicle speed; according to the method, the more reasonable vehicle speed control quantity is determined according to the historical vehicle speed capable of reflecting the actual execution condition of the automatic driving vehicle on the target vehicle speed, so that the target vehicle speed is closer to the real-time vehicle speed, and the problem of repeated vehicle speed correction is avoided.

    本发明提供了一种自动驾驶汽车的车速精准控制方法及系统。其中,所述方法包括:获取目标车速和实时车速,根据所述目标车速和所述实时车速计算偏差值;在所述偏差值大于阈值时,获取第一周期内的历史车速;根据所述历史车速计算下一时刻的车速控制量;本发明根据能够反映自动驾驶车辆对目标车速的实际执行情况的历史车速来确定出更为合理的车速控制量,使得目标车速和实时车速更为接近,从而避免了车速反复修正的问题。
