The invention discloses a vehicle suspension height adjusting method and device.The method comprises the steps that when a vehicle runs on a road, road surface height change data are obtained in real time, and the road condition of the current road is determined; when it is determined that the road condition is the target road condition, map road information of a current road on a preset high-precision map and sensor road information collected by a sensor are obtained; when it is determined that the vehicle travels on the current road, historical road information when the vehicle travels on the current road is obtained; based on the map road information, the sensor road information and the historical road information, the target height of a suspension enabling the vehicle to stably pass through the current road is determined; and adjusting the suspension height of the vehicle according to the target height. According to the scheme, the high-precision map, the sensor and the historical road information are fused to jointly determine the target height, the accuracy of suspension height calculation is improved, the road information is responded in time, the vehicle runs stably, and the service life of the vehicle is prolonged.

    本发明公开了一种车辆悬架高度调节方法和装置,该方法包括:当车辆在道路上行驶时,实时获取路面高度变化数据,并确定当前道路的路况;当确定路况为目标路况时,获取当前道路在预设的高精地图上的地图道路信息、传感器采集到的传感器道路信息;当确定车辆在当前道路上行驶过时,获取车辆在当前道路行驶时的历史道路信息;基于地图道路信息、传感器道路信息和历史道路信息,确定使车辆平稳通过当前道路的悬架的目标高度;根据目标高度调节车辆的悬架高度。在本方案中,将高精地图、传感器和历史道路信息三者融合共同确定目标高度,提高了悬架高度计算的准确性,并且对道路信息及时做出响应,使车辆平稳行驶,延长了车辆使用寿命。
