Abstract
A system for preventing shifting between a plurality of gear ratios in a mechanical gearset. An operating sensor detecting rotation of a moving component in the mechanical gearset, a shift solenoid controlling shifting among the plurality of gear ratios, and a microcontroller communicatively coupled to the shift solenoid and the operating sensor that prevents activation of the shift solenoid when rotation is detected by the rotation sensor.

A system for preventing shifting between a plurality of gear ratios in a mechanical gearset comprising:
- a rotation sensor detecting rotation of a moving component in the mechanical gearset;
- a shift solenoid controlling shifting among the plurality of gear ratios;
- and
- a microcontroller communicatively coupled to the shift solenoid and the rotation sensor that prevents activation of the shift solenoid when rotation is detected by the rotation sensor.
A system for preventing shifting between a plurality of gear ratios in a mechanical gearset comprising:
- an operating sensor providing a signal indicative of the mechanical gearset being in operation;
- a shift solenoid and valve block controlling shifting among the plurality of gear ratios in the gearset;
- and
- a microcontroller communicatively coupled to the shift solenoid and the rotation sensor that prevents activation of the shift solenoid when the mechanical gearset is in operation.
A method for preventing shifting of a mechanical gearset when the gearset is in operation comprising:
- providing an operating sensor detecting rotation of an internal component of the mechanical gearset;
- and
- providing a microcontroller communicatively coupled to the operating sensor;
- wherein the microcontroller prevents a shift solenoid of the mechanical gearset from initiation a change of input/output ratio of the mechanical gearset when the internal component of the mechanical gearset is rotating.
