Abstract
A shock absorber damping force control system for a vehicle employs at least a high-frequency component included in sprung mass vibration as a factor to control a damping force of a shock absorber. The system provides a lower damping force of the shock absorber with a larger magnitude of the high-frequency component when signs of a sprung mass velocity and a relative velocity between a sprung mass and an unsprung mass coincide with each other. A low-frequency component may also be employed as a factor to control the damping force of the shock absorber. The system provides a lower damping force with a larger ratio of the high-frequency component relative to the low-frequency component when signs of the sprung mass velocity and the relative velocity coincide with each other.
