Abstract
A ground contact pressure controller may be configured to automatically manage tire inflation pressure in a pneumatic compactor machine. The controller may determine a target tire inflation pressure for the machine according to the parameters of, inter alia, machine weight, number of tires on the machine, ground contact area of the tires, compaction surface type, and ambient temperature. The machine may include a compressor and vent unit coupled to the pneumatic tires, and the compressor and vent unit may be configured to adjust the tire pressure of the pneumatic tires according to a target tire pressure. A unified pressure subsystem coupled to the compressor and vent unit may be configured to measure pressure of the tires, and to adjust tire pressure to the target pressure.
