Abstract
A method of determining an engagement position of a clutch of a vehicle is provided. The clutch is operable by a clutch pedal adapted to move over a travel range. The method comprises determining a rate of change of position of the clutch pedal, locating a dwelling range of the clutch pedal, the dwelling range comprising a plurality of positions of the clutch pedal along the travel range during which the rate of change of position of the clutch pedal is less than a predetermined rate of change for a predetermined length of time, and recording the travel positions of the clutch pedal in the dwelling range.

A method of determining an engagement position of a clutch of a vehicle, the clutch operable by a clutch pedal adapted to move over a travel range, and the method comprising:
- determining a rate of change of position of the clutch pedal;
- locating a dwelling range of the clutch pedal, the dwelling range comprising a plurality of positions of the clutch pedal along the travel range during which the rate of change of position of the clutch pedal is less than a predetermined rate of change for a predetermined length of time;
- and
- recording the travel positions of the clutch pedal in the dwelling range.
A method of determining an engagement position of a clutch of a vehicle, the clutch operable by a clutch pedal adapted to travel over a travel range, the method comprising:
- receiving sensor data indicating a travel position of the clutch pedal;
- determining, from the sensor data, a positional rate of change of the clutch pedal;
- locating a first travel position of the clutch pedal at which the positional rate of change is less than a predetermined rate of change during a predetermined length of time;
- and
- recording the first travel position of the clutch pedal.
A clutch system for a vehicle, the clutch system comprising:
- a clutch manipulator adapted to operate over a travel range;
- a sensor adapted to obtain sensor data indicative of a travel position of the clutch manipulator, the travel position being within the travel range;
- and
- a processing architecture coupled to the sensor and adapted to:
- receive the sensor data;
- determine, from the sensor data, the travel position of the clutch manipulator relative to the travel range;
- determine, from the sensor data, a positional rate of change of the clutch manipulator over time;
- compare the positional rate of change to a predetermined rate of change;
- and
- locate a dwelling range of the clutch manipulator along the travel range during which the positional rate of change is less than the predetermined rate of change for at least a predetermined length of time.
