The invention discloses an air spring suspension, a control method, a vehicle-mounted controller and an automobile. The air spring suspension comprises a main air cylinder and at least one outer air cylinder, a main air cavity is arranged in the main air cylinder, the outer air cylinder is assembled on the main air cylinder, an outer air cavity is arranged in the outer air cylinder, and the outer air cavity is communicated with the main air cavity through an air cavity switch. According to the air spring suspension, different rigidity characteristics can be quickly switched through the air cavity switch, so that the rigidity adjustable range is widened, the vehicle driving smoothness is better, and the riding comfort is improved; and in addition, the suspension rigidity can be adjusted in real time under the transient working condition of the vehicle, the supporting performance is improved, and the control stability of the vehicle can be improved.
本发明公开一种空气弹簧悬架、控制方法、车载控制器及汽车。该空气弹簧悬架,包括主气缸,主气缸内设有主气腔,还包括至少一个外气缸,外气缸装配在主气缸上,外气缸内设有外气腔,外气腔与主气腔通过气腔开关连通。该空气弹簧悬架可通过气腔开关,快速切换出不同的刚度特性,从而拓宽刚度可调的范围,车辆行驶平顺性更好,提高乘坐舒适性;且可实现车辆在瞬态工况下实时调节悬架刚度,提高支撑性,有利于车辆操控稳定性的提高。
