The invention discloses a multi-parameter self-powered active suspension capable of being autonomously controlled and a control method thereof in the field of automobiles. The upper portion of a first oil cylinder of an anti-resonance structure is sequentially connected with an inerter pipe, a third adjustable throttling valve, an intelligent switch, a fourth electromagnetic valve and a fourth oil gas chamber in series. A third electromagnetic valve and a third oil gas chamber are connected in series and then connected to the two ends of the third adjustable throttle valve and the intelligent switch which are connected in series in parallel; a second adjustable throttling valve, a first adjustable throttling valve, a second oil gas chamber, a first electromagnetic valve and a first oil gas chamber are sequentially connected in series with the lower portion of a second oil cylinder of a traditional vibration reduction structure, and second electromagnetic valves are connected in parallel with the two ends of the first adjustable throttling valve. The intelligent switch is connected with the suspension domain controller, and the suspension domain controller is connected with the chassis system controller; the first oil cylinder and the second oil cylinder are staggered in a non-coaxial mode and are oppositely arranged, the installation distance of the suspension in the vertical direction is reduced, and an automobile obtains good high-speed driving safety and bad road riding comfort through autonomous control of an intelligent switch or connection pipe control of a chassis system controller.
本发明公开汽车领域中的一种多参数可自治控制的自供能主动悬架及其控制方法,反共振结构的第一油缸上部依次串联惯容管、第三可调节流阀、智能开关、第四电磁阀和第四油气室,第三电磁阀与第三油气室串联后并联在串联后的第三可调节流阀与智能开关的两端;传统减振结构的第二油缸下部依次串联第二可调节流阀、第一可调节流阀、第二油气室、第一电磁阀与第一油气室,第一可调节流阀两端并联第二电磁阀;智能开关连接悬架域控制器,悬架域控制器与底盘系统控制器相连;将第一、第二油缸非同轴错开且相反布置,减小悬架在垂向上的安装距离,通过智能开关自治控制或由底盘系统控制器接管控制,使汽车获得较好的高速行驶安全性及坏路乘坐舒适性。
