The invention discloses a shock absorber control method, a controller, a device, a system, an automobile and a storage medium. The method comprises the following steps: determining basic control current according to wheel acceleration and vehicle speed; determining a vehicle body control current according to the vehicle body pitch angle speed and the vehicle body roll angle speed; linear ceiling damping calculation is carried out on the vehicle body vertical acceleration, the vehicle body pitch angle speed, the vehicle body roll angle speed and the wheel acceleration, and linear ceiling control current is determined; performing modal ceiling damping calculation on the vehicle body vertical acceleration, the vehicle body pitch angle speed, the vehicle body roll angle speed and the wheel acceleration, and determining a modal ceiling control current; according to the basic control current, the vehicle body control current, the linear ceiling control current and the modal ceiling control current corresponding to each shock absorber, target control current is determined; and based on the target control current corresponding to each shock absorber, controlling the shock absorber to work. According to the damper control method, the real vehicle control effect can be guaranteed, and the real vehicle control accuracy is improved.
