The invention provides an automobile semi-active suspension control method and device. The method comprises the following steps: periodically acquiring suspension information and wheel speed information of each wheel of an automobile; judging whether each wheel is in a wheel jump vibration state or not and whether control current is output for the wheel or not; if so, outputting a preset basic control current; if the control current is in the current state and is output, calculating based on the current value of the last output control current and a preset increment current value to obtain a current control current value; determining an output current value according to the current control current value, and outputting a control current; and if the current value is not in the current state and is output, performing calculation based on the current value of the last output control current and a preset reduced current value to obtain a current control current value and output the control current. Whether the wheel is in the wheel jump vibration state or not is judged according to the suspension information and the wheel speed information of the wheel, further, the control current value needing to be output is calculated according to the wheel jump vibration state of the wheel, the current working condition can be well adapted, and the control effect is improved.
本发明提供一种汽车半主动悬架控制方法及装置,周期性获取车辆各个车轮的悬架信息和轮速信息;判断每个车轮是否处于轮跳振动状态,以及是否已针对车轮输出控制电流;若处于且未输出,输出预设基础控制电流;若处于且已输出,基于上一输出的控制电流的电流值和预设增量电流值进行计算,得到当前控制电流值;根据当前控制电流值确定输出电流值,并输出控制电流;若未处于且已输出,基于上一输出的控制电流的电流值和预设减少电流值进行计算,得到当前控制电流值并输出控制电流。根据车轮的悬架信息和轮速信息判断车轮是否处于轮跳振动状态,进一步的,根据车轮的轮跳振动状态计算需要输出的控制电流值,能够较好的适应当前工况,提高了控制效果。
