The invention relates to a driving speed control method and system based on automatic driving, and the method comprises the steps: receiving an input signal of a vehicle, and carrying out the data preprocessing of the input signal of the vehicle; performing scene decision on the preprocessed data, and screening out a target scene; performing longitudinal speed planning on the target scene to obtain planned data; the longitudinal speed planning comprises the step of sequentially calculating the distance, the speed and the acceleration of the target; according to the planned data, vehicle longitudinal control is carried out through a vehicle longitudinal control module; parameters of different scenes are simplified, the vehicle is reasonably planned and controlled under scene switching, the vehicle running process is smooth, and the pause feeling is reduced.
本发明涉及一种基于自动驾驶的行车速度控制方法及其系统,方法包括:接收车辆的输入信号,对车辆的输入信号进行数据预处理;对预处理后的数据进行场景决策,筛选出目标场景;对目标场景进行纵向速度规划,得到规划后的数据;纵向速度规划包括对目标依次进行距离、速度、加速度计算;根据规划后的数据,通过车辆纵向控制模块进行车辆纵向控制;本发明简化不同场景的参数,在场景切换下对车辆进行合理规划控制、使车辆行驶过程平滑,减少顿挫感。
