Patent ID: 8838347

Claim:
A compactor machine comprising: a pneumatic tire; a compressor and vent unit coupled to the pneumatic tire, the compressor and vent unit configured to adjust the tire pressure of the pneumatic tire according to a target tire pressure; a unified pressure subsystem coupled to the compressor and vent unit configured to: measure the tire pressure of the pneumatic tire, and transmit the adjustment tire pressure to the compressor and vent unit; and a controller configured to: determine a target tire inflation pressure for a pneumatic compactor according to: a weight of the pneumatic compactor; a number of tires of the pneumatic compactor; a ground contact area of the tires; a compaction surface type; an ambient temperature, determine a tire adjustment pressure according to the difference between a current tire pressure and the target tire pressure; and transmit the tire adjustment pressure to the unified pressure subsystem.
