A hydraulic damping system for damping pivoting movements of two vehicle parts which are at least indirectly connected to each other via a pivot joint has at least one damper configured as a double-acting hydraulic cylinder. Pressure and suction pressure chambers of this hydraulic cylinder are connected to each other via a proportional pressure relief valve. To provide a hydraulic damping system, the function of which is improved, wherein this can be produced with cost-effective means, the proportional pressure relief valve is to be configured as an electrically pilot-controlled inverse proportional pressure relief valve, with which a nominal pressure is adjustable in the de-energized state of a proportional solenoid or in a failure of the electromagnetic actuation in the damping system.
