The invention discloses an automobile vibration improving method, a control device and an automobile, and relates to the technical field of automobile design, and the automobile vibration improving method comprises the following steps that air spring change strokes and corresponding driving shaft included angles of the automobile in a plurality of preset modes are obtained, and a parameter set is formed; the acceleration amplitude corresponding to each air spring change stroke and the driving shaft included angle parameter set under the condition that the automobile is rapidly accelerated at multiple preset speed vehicle speed sections is obtained; comparing an acceleration target value with the plurality of acceleration amplitudes to obtain a plurality of acceleration excess amplitudes higher than the acceleration target value; and the multiple acceleration excess amplitudes are adjusted, so that the multiple acceleration excess amplitudes are not higher than the acceleration target value. By means of the arrangement, the NVH performance target can be achieved all the time when the automobile runs, and the NVH performance of the whole automobile batch can be effectively guaranteed.
本发明公开了一种汽车振动改善方法、控制装置及汽车,涉及汽车设计技术领域,其中,汽车振动改善方法包括以下步骤:获取汽车在多个预设模式下的空簧变化行程与对应的驱动轴夹角,并组成参数组;获取所述汽车在多个预设速度车速段急加速下,每一所述空簧变化行程以及驱动轴夹角参数组对应的加速度幅值;比对加速度目标值以及多个所述加速度幅值,以得到多个高于所述加速度目标值的加速度过量幅值;调节多个所述加速度过量幅值,以使多个所述加速度过量幅值不高于所述加速度目标值。如此设置,能够使所述汽车在运行时始终达到NVH性能目标,并且能够有效保证整车批的NVH性能。
