Abstract: The present invention provides a suspension control device with which the damping coefficient of the suspension can be easily adjusted on the basis of only the vertical vibration of a body of a vehicle, without measurement of the relative velocity or the relative displacement between the body and the wheel along the vertical direction. The absolute velocity of the body 1 is calculated on the basis of the detected signal of the acceleration sensor attached to the body 1, then the rotation angle .theta. of the movable plate is calculated on the basis of the absolute velocity, and the movable plate is rotated in the predetermined direction by the rotation angle .theta.. Accordingly, the damping coefficient is adjusted so that the coefficient in the extension of the shock absorber becomes larger and the coefficient in the compression of the shock absorber becomes smaller, or so that the damping coefficient in the extension becomes smaller and the coefficient in the compression becomes larger.

Abstract: A damping force control type hydraulic shock absorber has a piston that has main hydraulic fluid passages and valve mechanisms and also has a piston rod connected thereto. One side of the cylinder of the shock absorber is provided with a damping force control mechanism having a guide member and a shutter, which open and close a bypass passage, and a valve mechanism that generates damping force by controlling the flow of hydraulic fluid through the bypass passage. Damping force characteristics are changed by rotating the shutter with a rotary actuator. Since the damping force control mechanism is provided on the side of the cylinder and the piston is provided with only the main hydraulic fluid passages and the valve mechanisms, the size of the piston assembly is relatively small. Accordingly, the stroke of the piston rod can be increased.

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.

Abstract: In order to ensure riding comfort and driving stability in an automotive suspension system, the nature of the effect of the damping force generated by the suspension system is observed. When the damping characteristics of the suspension system are too hard, resulting in amplification of vibrations in the suspension system, the damping characteristics are softened to ensure satisfactory riding comfort. Therefore, according to the present invention, an automotive suspension system has variable damping characteristics which depend on the nature of the damping force produced in response to bounding and/or rebounding motion of the vehicle so as to optimize damping characteristics to achieve both riding comfort and driving stability. In the preferred embodiment, a suspension control system uses the vibration frequency of a sprung mass and the relative speed between the sprung mass and an unsprung mass as control parameters representing the nature of damping force.

Abstract: In a vehicle suspension control in which the output of a vehicle body mounted absolute vertical acceleration sensor is integrated to provide an absolute vertical velocity signal, the sensor output is high pass filtered to remove DC components but pass components in the frequency range 1-2 Hz. The filter comprises a second order digital all-pass filter embodied recursively on a 16 bit, fixed point, digital signal processor (DSP). A first stage normalized lattice two-pair network reduces to a unity gain stage; and a second stage single multiplier two-pair lattice network minimizes computational time. The 32 bit internal accumulators of the 16 bit DSP are used advantageously to prevent errors due to internal overflow of the recursive variable.
