Open the CIPO recordAbstract From the Canadian patent
A method for control of a tire pressure management system (or central tire inflation system) is provided which enables active adaptation of control variables in the system in response to variations in air line volume. The air line volume in a conduit between an air source and a vehicle tire is determined. Subsequently, one or more values for control variables are adjusted in response to the air line volume and various parameters associated with the system are determined in response to the adjusted values of the control variables.

Why it's free to use
- Filed April 21, 2003 and granted January 29, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 21, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 21, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
