Self-adaptive control method for rigidity of air spring of vehicle seat

The invention discloses a vehicle seat air spring stiffness self-adaptive control method, which comprises the following steps: acquiring the mean square frequency of compressing and stretching an air spring in a vehicle seat shear type suspension system, and adjusting the air pressure of an air cavity of the air spring to enable the inherent frequency of the vehicle seat shear type suspension system to deviate from the mean square frequency. The rigidity of the air spring can be adjusted, so that the inherent frequency of the seat is far away from the road excitation frequency, the vibration isolation effect is achieved, and the riding comfort and controllability of a vehicle are improved. 发明公开了一种车辆座椅空气弹簧刚度自适应控制方法，包括：获取车辆座椅剪式悬挂系统中空气弹簧进行压缩和拉伸的均方频率，调整空气弹簧的气腔的气压使所述车辆座椅剪式悬挂系统的固有频率偏离所述均方频率。本发明可以调节空气弹簧的刚度，使座椅固有频率远离路面激励频率，达到隔振效果，提高车辆乘坐舒适性和操控性。
