Abstract

This object is achieved in method of operating a tire-inflation control system connected to tires of a vehicle for increasing and decreasing pressurization of the tires wherein after shutdown of the vehicle engine pressurization of the vehicle tires is increased. The tire pressure is maintained generally at a predetermined set-point level during normal operation of the vehicle, and after shutdown of the engine increasing tire pressure substantially above the set-point level. After restart of the engine pressurization is decreased automatically generally to the set-point level. Tire pressurization is increased with a predetermined delay after shutdown of the engine.

Claims

1. A method of operating a tire-inflation control system connected to tires of a vehicle for increasing and decreasing pressurization of the tires, the vehicle having an engine, the method comprising the steps of:

monitoring operation of the engine; and

after shutdown of the engine increasing pressurization of the vehicle tires.

2. The method defined in claim 1 further comprising the steps of:

maintaining tire pressure generally at a predetermined set-point level during normal operation of the vehicle; and

after shutdown of the engine increasing tire pressure substantially above the set-point level.

3. The method defined in claim 2, further comprising the step of

after restart of the engine decreasing pressurization generally to the set-point level.

4. The method defined in claim 1 wherein tire pressurization is increased with a predetermined delay after shutdown of the engine.
