The invention discloses a vehicle speed adaptive control method. The main points of the technical scheme are that a central controller, an environment acquisition unit, a vehicle body data acquisition unit and a vehicle speed control unit are provided; the method comprises a data acquisition step, an expected speed direct determination step, an expected distance calculation step, an initial expected speed calculation step, an expected speed comparison determination step, an acceleration determination step and a vehicle execution step. By means of the method, the vehicle can conduct self-adaptive adjustment on the speed of the vehicle according to environment changes, the vehicle can have the running speed closest to the maximum cruise speed set by a driver on the premise that running safety is considered, the vehicle keeps a proper distance from a front vehicle in the running process, and the running safety is high.

    本发明公开了一种车辆速度自适应控制方法,其技术方案要点是提供中央控制器、环境采集单元、车身数据采集单元以及车速控制单元,该方法包括有数据采集步骤、期望速度直接确定步骤、期望距离计算步骤、初始期望速度计算步骤、期望速度比较确定步骤、加速度确定步骤以及车辆执行步骤,该方法实现了车辆根据环境变化对自身速度进行自适应调节,使得车辆在兼顾行驶安全的前提下能够具有最接近驾驶员设定的最大巡航速度的行驶速度,使得车辆在行驶过程中与前车保持合适的距离,行驶安全性高。
