Tire inflation system and method of control
First Claim
Patent Images
1. A method of controlling a tire inflation system for a vehicle comprising:
- checking an inflation pressure of a tire when a tire pressure sampling interval has elapsed; and
inflating the tire when the inflation pressure is less than a target tire pressure;
wherein the tire pressure sampling interval is expressed in terms of distance and is measured based on a travel distance of the vehicle or wherein the tire pressure sampling interval is expressed in terms of time and is measured based on engine temperature or ambient temperature.

10. A method of controlling a tire inflation system comprising:
-
determining a tire pressure sampling interval for a tire; checking an inflation pressure of the tire when the tire pressure sampling interval has elapsed; checking the inflation pressure of the tire before the tire pressure sampling interval has elapsed based on data indicative of vehicle speed or wheel speed; and inflating the tire when the inflation pressure is less than a target tire pressure. - View Dependent Claims (11, 12, 13, 14)

15. A method of controlling a tire inflation system comprising:
-
determining a tire pressure sampling interval for a tire; checking an inflation pressure of the tire when the tire pressure sampling interval has elapsed; triggering a check of the inflation pressure of the tire before the tire pressure sampling interval has elapsed based on at least one of an ambient temperature and a wheel end temperature; and inflating the tire when the inflation pressure is less than a target tire pressure. - View Dependent Claims (16, 17, 18, 19, 20)
