Abstract
A method of clutch wear notification comprises detecting engaged clutch positions at a first interval and storing the values of the engaged clutch positions. The stored values of the engaged clutch positions can be averaged at a second interval to create running averages, and the running averages can be stored. The running averages are compared at a third interval to determine a rate of change in the clutch positions. A clutch wear-out is signaled when comparing the running averages indicates that the rate of change in the clutch positions deviates from a normal rate of change. The clutch position during an engaged condition can deviate from the normal rate of change when the axial position of the release bearing begins to increase due to an adjustment mechanism ceasing to adjust.
Claims14
A method of clutch wear notification, comprising;
- detecting engaged clutch positions at a first interval;
- storing the values of the engaged clutch positions;
- averaging the stored values of the engaged clutch positions at a second interval to create running averages;
- storing the running averages;
- comparing the running averages to determine a rate of change in the clutch positions;
- and
- signaling a clutch wear-out when comparing the running averages indicates that the rate of change in the engaged clutch positions deviates from a historical rate of change of engaged clutch positions.
A method of clutch wear notification, comprising;
- detecting clutch actuator positions of an engaged clutch at a first interval;
- storing the values of the clutch actuator positions;
- averaging the stored values of the clutch actuator positions at a second interval to create running averages;
- storing the running averages;
- comparing the running averages to determine a rate of change in the clutch actuator positions;
- and
- signaling a clutch wear-out when comparing the running averages indicates that the rate of change in the clutch actuator positions deviates from a historical rate of change of clutch actuator positions.
A method of clutch wear notification, comprising;
- detecting clutch actuator positions of an engaged clutch at a first interval;
- calculating positions of the engaged clutch by processing the detected clutch actuator positions;
- storing values of the calculated engaged clutch positions;
- averaging the stored values of the calculated engaged clutch positions at a second interval to create running averages;
- storing the running averages;
- comparing the running averages to determine a rate of change in the engaged clutch positions;
- and
- signaling a clutch wear-out when comparing the running averages indicates that the rate of change in the engaged clutch positions deviates from a historical rate of change of engaged clutch positions.
