The invention relates to a semi-active suspension damping compensation method and device, a medium and a vehicle. The method comprises the steps that when the vehicle speed is larger than a preset vehicle speed threshold value, relevant parameters of a vehicle vibration model are obtained, and the relevant parameters comprise the sprung acceleration and the unsprung acceleration; determining a transmissibility resonance peak value according to the related parameters; according to the transmissibility resonance peak value, the compensation current of a semi-active shock absorber of the semi-active suspension is determined; and if the compensation current is within the preset compensation current range, damping compensation is conducted on the semi-active shock absorber according to the compensation current. Due to the fact that the transmissibility resonance peak value can reflect the damping change of the semi-active shock absorber, the compensation current determined according to the transmissibility resonance peak value can adapt to the actual state of the semi-active shock absorber, differential damping compensation can be conducted on the semi-active shock absorber of each vehicle, the damping compensation accuracy is improved, and the service life of the semi-active shock absorber is prolonged. And the smoothness and the handling stability of the vehicle are improved.
本公开涉及一种半主动悬架阻尼补偿方法、装置、介质和车辆。该方法包括:在车辆车速大于预设的车速阈值时,获取车辆振动模型的相关参数,其中,相关参数包括簧上加速度和簧下加速度;根据相关参数,确定传递率共振峰值;根据传递率共振峰值,确定半主动悬架的半主动减振器的补偿电流;若补偿电流在预设的补偿电流范围内,则根据补偿电流,对半主动减振器进行阻尼补偿。因传递率共振峰值可反映半主动减振器的阻尼变化,故根据传递率共振峰值确定的出补偿电流,能够与半主动减振器的实际状态相适应,如此,可对每辆车的半主动减振器进行差异化的阻尼补偿,提高阻尼补偿的精确性,改善车辆的平顺性和操纵稳定性。
