Semi-Active Suspension to Determine Damping Stage by Emphasizing Vertical Motion

摘要

An acceleration sensor for detecting an acceleration in the vertical direction of the vehicle body and then converting the acceleration into an electric signal and outputting the signal; an integrator for integrating and outputting a signal input from the acceleration sensor; A step motor for generating power in accordance with the control signal outputted from the control means, and a variable damper for adjusting the number of damping stages by the power transmitted from the step motor And it is possible to perform optimum tuning according to the vehicle characteristics by changing the number of stages of the damper according to the running speed of the vehicle and to control the up and down motion mainly by the acceleration sensor value, To provide a semi-active suspension device for determining the number of damping stages.
