DAMPING FORCE CONTROL SYSTEM FOR SHOCK ABSORBER VARIABLE WITH FREQUENCY OF VEHICLE HEIGHT DIFFERENCE EXCEEDING LIMIT VALUE

摘要

In a damping force control system for switching over a shock absorber in the suspension of a vehicle from a low damping force operation to a high damping force operation when a vehicle height difference exceeds a certain limit value, the shock absorber is continually maintained at the high damping force operation for a substantially increased time duration when a frequency of vehicle height difference exceeding the certain limit value in a certain cycle period increases beyond a certain number.
