Bicycle component calibration device
A bicycle component calibration device and method are provided that assist the user in determining that an adjustment was made. Basically, when a calibration command in inputted to indicate a selected adjustment amount in a selected adjustment direction, the bicycle component (e.g., a derailleur) initially moves farther than the selected adjustment amount in a first direction by an adjustment indicating amount in response to the calibration command, and then subsequently moves the bicycle component in a second direction to the selected adjustment position in which the second direction is opposite to the first direction. The adjustment indicating amount is greater than the selected adjustment amount of the calibration command. Finally, the selected adjustment position is set as an adjusted position of the bicycle component.
1. A bicycle derailleur calibration method of calibrating a position of a bicycle derailleur comprising:
inputting a calibration command indicating a selected adjustment amount in a selected adjustment direction into an electronic controller;
initially moving the bicycle derailleur farther than the selected adjustment amount in a first direction by an adjustment indicating amount in response to the calibration command, the adjustment indicating amount being greater than the selected adjustment amount of the calibration command;
subsequently moving the bicycle derailleur in response to the calibration command in a second direction to the selected adjustment position in which the second direction is opposite to the first direction; and
setting the selected adjustment position as an adjusted position of the bicycle derailleur.
2. The bicycle derailleur calibration method according to claim 1 , wherein
the first direction and the selected adjustment direction are same direction.
3. The bicycle derailleur calibration method according to claim 1 , wherein
the inputting of the calibration command includes operating an input part at least once within a prescribed time period and setting the selected adjustment amount of the calibration command based a number of times that the input part was operated within the prescribed time period.
4. The bicycle derailleur calibration method according to claim 3 , wherein
the initially moving of the bicycle derailleur includes moving different amounts for the adjustment indicating amount depending on the number of times that the input part was operated within the prescribed time period; and
the subsequently moving of the derailleur includes setting the selected adjustment position differently depending on the number of times that the input part was operated within the prescribed time period.
5. The bicycle derailleur calibration method according to claim 1 , further comprising
updating a prestored reference value for a derailleur position to an updated reference value based on the adjusted position.
6. The bicycle derailleur calibration method according to claim 5 , wherein
the updating of the prestored reference value includes updating at least one additional prestored reference value for an additional derailleur position to an updated reference value based on the adjusted position.
7. A bicycle derailleur calibration device comprising:
a controller including a command detecting and setting part and a derailleur moving command part,
the command detecting and setting part being configured to detect a calibration command and to set a selected adjustment amount and a selected adjustment direction for the calibration command that was detected; and
the derailleur moving command part being configured to issue a movement command to initially move a bicycle derailleur farther than the selected adjustment amount in a first direction by an adjustment indicating amount in response to the calibration command, and then subsequently move the bicycle derailleur in response to the calibration command in a second direction to the selected adjustment position in which the second direction is opposite to the first direction and the adjustment indicating amount is greater than the selected adjustment amount.
8. The bicycle derailleur calibration device according to claim 7 , wherein the derailleur moving command part is further configured to issue the movement command such that the first direction and the selected adjustment direction are same direction.
9. The bicycle derailleur calibration device according to claim 7 , wherein
the command detecting and setting part is further configured to detect a number of operations of an input part within a prescribed time period and to set the selected adjustment amount based a number of times that the input part was operated within the prescribed time period.
10. The bicycle derailleur calibration device according to claim 9 , wherein
the derailleur moving command part is further configured to issue the movement command such that the bicycle derailleur is moved different amounts for the adjustment indicating amount depending on the number of times that the input part was operated within the prescribed time period.
11. The bicycle derailleur calibration device according to claim 7 , further comprising
a storage part with at least one prestored reference value for a derailleur position; and
a reference value updating part configured to update the prestored reference value for the derailleur position to an updated reference value based on the adjusted position.
12. The bicycle derailleur calibration device according to claim 11 , wherein the storage part has at least one additional prestored reference value for an additional derailleur position; and
the reference value updating part is further configured to update the additional prestored reference value for the derailleur position based on the adjusted position.
13. A bicycle control device including the bicycle derailleur calibration device according to claim 7 , wherein
the bicycle control device includes an input part configured to input the calibration command to the command detecting and setting part.
