The invention relates to an automatic adjustment method for a vehicle suspension system based on vehicle-road cooperation, which comprises a cloud device, a vehicle end device and a road end device which are matched with one another, and is characterized in that a high-precision map of the cloud provides positions and paving conditions of all roads in a map range and periodically updates the positions and the paving conditions; the road end sensor is provided with an edge computing node, detects and recognizes road conditions in real time, and reports real-time road condition information to the cloud end through wireless communication to serve as a supplementary part of high-precision map information. The positioning device assembled at the vehicle end and the vehicle-mounted T-Box send the acquired information to the calculation unit; the calculation unit generates a road condition model according to the obtained information in combination with the road condition information of the position and the nearby area and sends the road condition model to the suspension controller, and the suspension controller controls the state of the suspension actuator according to the road condition model. The method has the advantages that the road information can be accurately obtained, the dynamic information is updated in real time, the cost is reduced, and the recognition precision is improved.
本发明涉及一种基于车路协同的车辆悬挂系统自动调节方法,包括相互配合的云端设备、车端设备和路端设备,云端的高精地图提供地图范围内所有道路的位置和铺装情况并定期更新;路端传感器配有边缘计算节点,实时检测和识别路面情况,并通过无线通信将实时路况信息上报给云端,作为高精地图信息的补充部分;车端装配的定位装置和车载T‑Box将获取的信息发送给计算单元;计算单元根据获取的信息结合该位置及附近区域的路况信息,生成路况模型,并发送到悬挂控制器上,悬挂控制器根据路况模型控制悬挂执行器的状态。本发明的优点是可以准确获取道路信息,实时更新动态信息,降低成本,提高识别精度。
