A reengagement control system/method (200) for a semi-automatic mechanical transmission system (104) of the type requiring manual synchronization of the transmission to enable automatic implementation of a selected shift into a target gear ratio is provided. The reengagement control will cause immediate engagement of an engageable ratio, based upon vehicle speed if the, transmission is shifted to neutral and is then unable to engage in the target gear for greater than a predetermined time (REF2) as vehicle acceleration (dOS/dt) exceeds an acceleration reference value (REF1).

Why it's free to use
- Filed July 16, 1992 and granted May 25, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 16, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 16, 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.
