The invention discloses a semi-active suspension control method and system and a vehicle. The semi-active suspension control method comprises the steps that a current vehicle body attitude angle of a vehicle and current state information corresponding to a first shock absorber are obtained; determining a first anti-roll damping force, a first anti-pitching damping force and a first anti-bumping damping force of a first shock absorber according to the current state information and the current vehicle body attitude angle; determining a first target damping force of the first shock absorber according to the first anti-roll damping force, the first anti-pitching damping force and the first anti-bumping damping force, and adjusting the damping force of the first shock absorber to the first target damping force; determining a first delay duration according to the axle distance between the first axle and the second axle and the current state information; and second target damping force of the second shock absorber is determined according to the first target damping force, and the damping force of the second shock absorber is adjusted to be the second target damping force at the second moment. According to the invention, the stability and riding comfort of the vehicle in the driving process can be improved.

    本发明公开了一种半主动悬架控制方法、系统及车辆。半主动悬架控制方法包括:获取车辆的当前车身姿态角及第一减振器对应的当前状态信息;根据当前状态信息和当前车身姿态角确定第一减振器的第一抗侧倾阻尼力、第一抗俯仰阻尼力以及第一防颠簸阻尼力;根据第一抗侧倾阻尼力、第一抗俯仰阻尼力以及第一防颠簸阻尼力确定第一减振器的第一目标阻尼力,并将第一减振器的阻尼力调整为第一目标阻尼力;根据一轴与二轴之间的轴距和当前状态信息确定第一延迟时长;根据第一目标阻尼力确定第二减振器的第二目标阻尼力,并在第二时刻将第二减振器的阻尼力调整为第二目标阻尼力。本发明可以提高车辆在行驶过程中的稳定性和乘坐舒适性。
