The invention provides a vehicle vibration reduction method, a vehicle vibration reduction device, equipment and a medium, the vehicle vibration reduction method comprises the steps that the target suspension movement speed and the target suspension movement acceleration of a suspension assembly are determined according to the target suspension height obtained in advance, the target suspension height is used for representing the height of the suspension assembly, and the target suspension movement acceleration is used for representing the height of the suspension assembly; and according to the target suspension height and a preset first suspension height threshold value, the control level of the electromagnetic valve is determined, a first preset mapping relation table is inquired according to the control level, the target suspension movement speed and the target suspension movement acceleration, target driving current is obtained, and the electromagnetic valve is controlled through the target driving current to adjust the damping coefficient of the shock absorber. According to the vehicle vibration reduction method, vibration of the wheels relative to the vehicle body can be effectively attenuated, meanwhile, abnormal sound generated when the suspension collides with the suspension limiting device is avoided, and the driving comfort is improved. The invention relates to the technical field of vehicles.

    本申请提供一种车辆减振方法、车辆减振装置、设备及介质,其中,该车辆减振方法通过根据预先获取到的目标悬架高度确定悬架组件的目标悬架运动速度和目标悬架运动加速度,其中,目标悬架高度用于表征悬架组件的高度,根据目标悬架高度和预设的第一悬架高度阈值,确定电磁阀的控制等级,根据控制等级、目标悬架运动速度和目标悬架运动加速度对第一预设映射关系表进行查询,得到目标驱动电流,通过目标驱动电流控制电磁阀调整减振器的阻尼系数。该车辆减振方法能够有效衰减车轮相对于车身的振动,同时避免悬架撞击悬架限位产生异响,提高了驾乘的舒适性。本申请涉及车辆技术领域。
