Control device of a vehicle suspension

An agricultural utility vehicle, comprising:

• a frame;
• a vehicle suspension with a suspended front axle;
• and
• a control device including a suspension device mounted between a supporting vehicle structure and a vehicle part, a blocking device to block a compression or rebound motion occurring on the suspension device in accordance with a blocking command transmitted to a control unit;
• wherein, when the control unit sets the blocking command, the control unit determines a characteristic weight value for a current loading of the suspension device and stores it as a pertinent value in a memory unit;
• wherein, when the control unit resets the blocking command, the control unit determines a new value for the weight in order to cancel a blocking of the suspension device according to a result of a comparison with the values stored in the memory unit;
• wherein the control unit cancels the blocking command gradually while it maintains a preset unblocking sequence within a time span that is dependent on the comparison result.
