Abstract
A central tire inflation system for controlling the tire inflation pressure of a driven wheeled vehicle includes a compressed air source connected through a conduit system with the vehicle tires, a controllable valve system connected in the conduit system and a tire pressure controller connected with and controlling operation of the valve system to selectively increase or decrease inflation pressure includes wheel slip detectors and a vehicle speed detector for generating a signal proportional to detected slippage rate and vehicle speed, and signal processing system for utilizing the slippage signal and vehicle speed signals to control the valve system to automatically control tire inflation pressure in response to conditions encountered to minimize slippage and maintain tire inflation pressure at the highest pressure commensurate with safety and economic operation.
