The present invention relates to a method for determining an operative shift configuration of a drive mechanism () of a gearbox (G) of a saddle-ride type vehicle (). In particular, this method is applied to a drive mechanism () comprising a pedal shift lever () and a quick-shifter device () that connects, directly or indirectly, the lever to the gearbox, where this device includes a rod () and first sensor means (SM, SM-SM) that detect the variation of the tension state of said rod () following a gear shifting. The method according to the invention includes acquiring a first signal (S) generated by said first sensor means and determining, based on said first signal, whether the rod is in a traction tension state or in a compression tension state. The method also includes acquiring at least a second signal (S) generated by second sensor means (SM) and determining, based on this second signal (S), the gear engaged following said gear shifting and/or the direction of said gear shifting. Finally, the method includes determining the operative shift configuration of the drive mechanism based on the tension state determined in the step B) and the gear engaged and/or based on the direction of said gear shifting determined in the step D).

Method for determining an operative shift configuration of a drive mechanism of a gearbox of a saddle-ride type vehicle

A dynamic adjustment method while driving a vehicle of at least one vehicle operating parameter is for a vehicle having an electronic control unit adapted to set the operating parameter, and a communication interface operatively connected to the electronic control unit. An application program is installed on board a portable processing device including a communication interface communicating with the vehicle communication interface. The application program accesses an electronic map of a path and divides the path in sectors. Operating parameter values are stored via the application program, each value being associated to a corresponding sector. While driving, the sector occupied by the vehicle is identified in real time. Values are transmitted sector by sector, from the portable processing device to the electronic control unit so that the electronic control unit sets, sector by sector, the vehicle operating parameter vehicle to the value associated to the occupied sector.
