The invention provides an active suspension control method and device, a vehicle controller, a medium and a vehicle. The active suspension control method comprises the following steps: acquiring geometric feature information and relative position information of a plurality of road objects in a road in front of a vehicle; based on the geometric feature information and the relative position information of each road object, the driving state parameters of the vehicle and the performance parameters of the active suspension, first feed-forward control quantities are calculated, and the first feed-forward control quantities comprise the suspension height control quantity and the spring stiffness control quantity; when the vehicle passes through the road ahead, the active suspension is controlled by adopting the first feedforward control quantity. According to the scheme provided by the embodiment of the invention, the global first control quantity is determined by considering the geometric features and the position features corresponding to the plurality of road objects in the front, so that the state of the active suspension adapts to all road objects in the front road as much as possible when the vehicle passes through the front road; and therefore, the vehicle is ensured to have better driving stability when passing through each road object.
本公开提供一种主动悬架控制方法、装置、车辆控制器、介质和车辆。其中主动悬架控制方法,包括:获取车辆前方道路中的多个道路对象的几何特征信息和相对位置信息;基于各个道路对象的几何特征信息和相对位置信息,以及车辆的行驶状态参数和主动悬架的性能参数,计算第一前馈控制量,第一前馈控制量包括悬架高度控制量和弹簧刚度控制量;在车辆经过前方道路时,采用第一前馈控制量控制主动悬架。本公开实施例提供的方案考虑到前方多个道路对象对应的几何特征和位置特征,确定全局的第一控制量,使得在经过前方道路时,主动悬架的状态尽可能地适应前方道路中的所有道路对象,继而保证车辆经过各个道路对象时均具有较好的行驶稳定性。
