CONTROLLER FOR DAMPING FORCE-VARIABLE TYPE OIL-PRESSURE SHOCK ABSORBER

摘要

PURPOSE:To prevent the lowering of damping force to less than a low damping force as a set reference by a method in which when the temperature of working oil for the shock absorber reaches more than a value, the setting condition of low damping forces is corrected to the setting condition of higher damping forces. CONSTITUTION:The temperature of working oil packed in a shock absorber is detected by an oil temperature sensor 31. When the oil temperature reaches more than a preset value, an oil temperature correction circuit 30 works to correct selected reference signal output corresponding to low damping force setting position S from a selected reference signal generation circuit 2 to a selected reference signal output corresponding to higher damping force setting position N. The signal output is put in a signal comparator circuit 3 to prevent the lowering of the damping force. Low damping force as a design reference can thus be maintained.
