The invention provides a shock absorber damping force attenuation self-learning method, a suspension controller and a readable storage medium. The method comprises the steps that current driving condition information, current shock absorber speed information and current shock absorber height information of a target vehicle are acquired; according to the current driving condition information, standard shock absorber speed information and standard shock absorber height information under the corresponding driving condition are searched in a pre-created standard shock absorber database; according to the current shock absorber speed information, the current shock absorber height information, the standard shock absorber speed information and the standard shock absorber height information, whether the damping force of the shock absorber is attenuated or not is judged; if yes, the current compensation value of the shock absorber electromagnetic valve is calculated according to the current shock absorber height information and the standard shock absorber height information. The problems of poor vehicle body control and reduced riding comfort caused by performance attenuation of the shock absorber can be effectively relieved, and the smoothness of a vehicle in the running process is improved.
本发明提供了一种减振器阻尼力衰减自学习方法、悬架控制器和可读存储介质,该方法包括:获取目标车辆的当前驾驶工况信息、当前减振器速度信息和当前减振器高度信息;根据当前驾驶工况信息,在预先创建的标准减振器数据库中查找出对应驾驶工况下的标准减振器速度信息和标准减振器高度信息;根据当前减振器速度信息、当前减振器高度信息、标准减振器速度信息和标准减振器高度信息,判断减振器的阻尼力是否衰减;若是,则根据当前减振器高度信息和标准减振器高度信息,计算减振器电磁阀的电流补偿值。本发明可以有效缓解因减振器性能衰减导致的车身控制差和乘坐舒适性下降的问题,提升车辆行驶过程中的平顺性。
