The invention relates to the technical field of suspension control, and provides a semi-automatic suspension control method and system, a suspension, a vehicle and electronic device.When acceleration sensors are arranged on a sprung part and an unsprung part respectively, the method comprises the steps that a first signal and a second signal representing the speed of the sprung part and the speed of the unsprung part are obtained respectively; determining a third signal characterizing a relative movement speed of the semi-automatic suspension based on the first and second signals; when the first reference parameter is larger than the square of the second signal, the semi-automatic suspension is controlled based on the damping coefficient determined according to the first execution strategy; and when the damping coefficient is not greater than the square of the second signal, controlling the semi-automatic suspension based on the damping coefficient determined according to the second execution strategy. The method is used for overcoming the defects that in the prior art, a ceiling control algorithm is used for controlling the semi-automatic suspension, the suppression effect on medium-high frequency vibration is poor, and the ceiling control algorithm and a damping control algorithm are combined for controlling the semi-automatic suspension, and serious extremely high frequency response is usually accompanied.
本发明涉及悬架控制技术领域,提供一种半自动悬架控制方法、系统、悬架、车辆及电子设备,其中在簧上和簧下部件上分别布置加速度传感器时,方法包括:分别获取表征簧上和簧下部件的速度的第一和第二信号;基于第一和第二信号,确定表征半自动悬架的相对运动速度的第三信号;在第一基准参数大于第二信号的平方时,基于按照第一执行策略确定的阻尼系数控制半自动悬架;在不大于第二信号的平方时,基于按照第二执行策略确定的阻尼系数控制半自动悬架。本发明用以解决现有技术中通过天棚控制算法对半自动悬架进行控制,对于中高频振动的抑制效果不佳,而通过天棚控制算法与阻尼控制算法结合对半自动悬架进行控制,通常又伴随严重的极高频响应的缺陷。
