The invention provides a vehicle speed smoothing method and device, and belongs to the technical field of vehicle speed control, and the method comprises the steps: obtaining an actual vehicle speed and a target vehicle speed of a vehicle in a cruise state, obtaining a speed difference value based on the actual vehicle speed and the target vehicle speed, and when the speed difference value is determined to be greater than or equal to a first speed threshold value, outputting a smoothing result; and on the basis of a model prediction control algorithm, smoothing processing is conducted on the speed difference value, preset recovery time and the obtained vehicle speed fuel consumption function under the preset adjustment times, the adjustment speed corresponding to the preset adjustment times is obtained, and vehicle speed adjustment is conducted on the basis of the adjustment speed corresponding to the preset adjustment times. The technical problems that in the prior art, rapid acceleration or rapid deceleration in predictive cruise causes too large oil consumption and affects riding comfort are solved.
本发明提供了一种车辆速度平滑处理方法及装置,属于车辆速度控制技术领域,其方法包括:获取车辆在巡航状态中的实际车速和目标车速,基于实际车速和目标车速,得到速度差值,在确定速度差值大于或等于第一速度阈值时,基于模型预测控制算法在预设的调整次数下,对速度差值、预设恢复时间和获取的车辆速度油耗函数进行平滑处理,得到预设的调整次数所对应的调整速度,基于预设的调整次数所对应的调整速度进行车辆速度调整。本发明解决了现有技术中存在的预见性巡航中急加速或急减速,从而导致油耗过大和影响乘车舒适性的技术问题。
