摘要： 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.

摘要： A suspension control system for an automotive vehicle is provided which is operable to control transmission of vibratory energy from a road surface to a vehicle body. This suspension control system includes a variable damping force shock absorber, a vertical speed sensor which detects vertical speed of the vehicle body, a relative displacement speed sensor which detects the relative displacement between the vehicle body and a road wheel, and a damping force control unit which is operable to modify a damping force of the variable damping force shock absorber over a range from preselected maximum to minimum values based on the vertical speed and the relative displacement speed. When the vertical speed and the relative displacement speed are smaller than preselected first and second threshold values respectively during vibratory motion of the vehicle body wherein the vertical speed and the relative displacement speed are in the same phase, the damping force control unit controls the variable damping force shock absorber to produce the damping force of a level smaller than the maximum value by a preselected value.
