The invention provides an electromagnetic type semi-active suspension, a vehicle and a control method, and the electromagnetic type semi-active suspension comprises an outer shell which is provided with a containing cavity; the suspension assembly is movably arranged in the containing cavity, a permanent magnet is arranged at one end of the suspension assembly, and the other end of the suspension assembly is connected with the power assembly; and the electromagnet assembly is connected with the outer shell, and under the condition that the electromagnet assembly is in a power-on state, repulsive force is generated between the electromagnet assembly and the permanent magnet assembly, so that the end, provided with the permanent magnet, of the suspension assembly is suspended in the containing cavity. According to the technical scheme, the end, provided with the permanent magnet, of the suspension assembly is suspended in the containing cavity, large rigidity and damping are provided for supporting the power assembly, then the technical effect that the rigidity of the lower suspension is improved in the starting working condition and the low and medium-frequency driving working condition is achieved, the problem that in the prior art, the NVH performance of a vehicle is poor is solved, and the service life of the vehicle is prolonged. And the practicability of the electromagnetic type semi-active suspension is improved.
本发明提供了一种电磁式半主动悬置、车辆及控制方法,电磁式半主动悬置包括:外壳体,外壳体具有容纳腔;悬置组件,悬置组件可活动地设置于容纳腔内,悬置组件的一端设置有永磁体,悬置组件的另一端与动力总成连接;电磁铁组件,电磁铁组件与外壳体连接,电磁铁组件处于通电状态的情况下,电磁铁组件与永磁体组件之间产生排斥力,以使悬置组件设置有永磁体的一端悬浮于容纳腔内。应用本申请的技术方案,以使悬置组件设置有永磁体的一端悬浮于容纳腔内,提供较大的刚度和阻尼来对动力总成进行支撑,进而实现启动工况及中低频行驶工况中下悬置刚度提升的技术效果,解决现有技术中车辆的NVH性能不佳的问题,提高了该电磁式半主动悬置的实用性。
