Open the CIPO recordAbstract From the Canadian patent
A speed controller maintains the engine throttle at a desired throttle position based upon an initial throttle position and a speed error signal. The initial throttle position is generated by multiplying vehicle speed by a constant and adding an offset value related to throttle position at idle and speed control slack. The initial throttle position is adaptively updated by subtracting the above product from actual throttle position during speed control operation to learn a new offset value.

Why it's free to use
- Filed July 30, 1992 and granted June 5, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 30, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 30, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
