The condition changing unit 18 may be configured as an element included in the control unit 16.

  For example, when the first condition is satisfied in the success / failure determination, the condition changing unit 18 changes the shift condition so that the shift condition is less likely to be satisfied. In this case, the condition changing unit 18 changes the speed change condition so as to widen the hysteresis width that defines the hysteresis characteristic. The condition changing unit 18 may change the first threshold TH1 so that the first threshold TH1 is separated from the second threshold TH2, and changes the second threshold TH2 so that the second threshold TH2 is separated from the first threshold TH1. Alternatively, the threshold values TH1 and TH2 may be changed so that the first threshold value TH1 and the second threshold value TH2 are separated from each other. The solid line threshold values TH1 and TH2 shown in FIG. 3 are examples of the threshold values TH1 and TH2 before the change. The two-dot chain line threshold values TH1 and TH2 shown in FIG. 3 are examples of the changed threshold values TH1 and TH2 that have been changed so that the shifting conditions are less likely to be satisfied.

  For example, when the second condition is satisfied in the success / failure determination, the condition changing unit 18 changes the speed change condition so that the speed change condition is easily satisfied. In this case, the condition changing unit 18 changes the speed change condition so as to narrow the hysteresis width. The condition changing unit 18 may change the first threshold TH1 so that the first threshold TH1 approaches the second threshold TH2, and changes the second threshold TH2 so that the second threshold TH2 approaches the first threshold TH1. Alternatively, the threshold values TH1 and TH2 may be changed so that the first threshold value TH1 and the second threshold value TH2 approach each other. Dotted line threshold values TH1 and TH2 shown in FIG. 3 are examples of changed threshold values TH1 and TH2 that have been changed so that the shifting conditions are easily established.

The condition changing unit 18 changes the shift condition for executing the first shift according to at least one of the success / failure determinations for the first shift that is a shift from the first shift stage to the second shift stage. That is, the condition changing unit 18 changes the threshold value TH that defines the shift condition according to at least one of the success determination and the failure determination in the success / failure determination for the first shift.

  In the success / failure determination with respect to a predetermined shift that is a shift from a predetermined shift stage to another shift stage, for example, when the number of failure determinations is equal to or greater than the first predetermined number, the condition changing unit 18 It is determined that the condition is satisfied.

In one example, the condition changing unit 18 determines that the first condition is satisfied when the number of failure determinations in the success / failure determination for the first shift is equal to or greater than a first predetermined number. Specifically, the condition changing unit 18 shifts the gear so that the shift condition for executing the first shift is less likely to be satisfied when the success / failure determination for the first shift is equal to or greater than the first predetermined number. Change the condition.

  For example, in the success / failure determination for the predetermined shift, the condition changing unit 18 determines that the second condition is satisfied when the number of successful determinations is equal to or greater than the second predetermined number. The second predetermined number of times is set in advance based on, for example, a general success rate related to shifting. When the number of success determinations is equal to or greater than the second predetermined number, it is assumed that the degree of deterioration of the front derailleur TF, the rear derailleur TR, the planned shift front sprocket D1, the planned shift rear sprocket D2, and the chain D3 is low. The In one example, the condition changing unit 18 determines that the second condition is satisfied when, for example, the success / failure determination for the first shift is not less than the second predetermined number. Specifically, the condition changing unit 18 changes the speed so that the speed change condition for executing the first speed change is easily established when the success / failure count for the first speed change is equal to or greater than the second predetermined number of times.

For example, when the third condition is satisfied in the shift history, the control unit 34 changes the shift condition so that the shift condition is less likely to be satisfied. For example, when the fourth condition is satisfied in the shift history, the control unit 34 changes the shift condition so that the shift condition is easily satisfied. In the present embodiment, the control unit 34 changes the shift condition according to the number of shifts of the transmission T. The control unit 34 changes a shift condition for executing the first shift according to the number of shifts of the first shift that is a shift from the first shift stage to the second shift stage.

For example, when the number of shifts of the predetermined shift is equal to or greater than the third predetermined number, the control unit 34 determines that the third condition is satisfied. The third predetermined number of times is set in advance based on, for example, the relationship between the number of shifts of the predetermined shift and a general failure rate related to the shift. When the number of shifts of the predetermined shift is equal to or greater than the third predetermined number of times, it is assumed that the failure rate related to the shift becomes high. That is, when the number of shifts of the predetermined shift is equal to or greater than the third predetermined number of times, at least one deterioration of the front derailleur TF, the rear derailleur TR, the planned front shift sprocket D1, the planned shift rear sprocket D2, and the chain D3. Is expected to be high. In one example, the control unit 34 determines that the third condition is satisfied when the number of shifts of the first shift is equal to or greater than a third predetermined number. Specifically, when the number of shifts of the first shift is equal to or greater than the third predetermined number, the control unit 34 changes the shift conditions so that the shift condition for realizing the first shift is less likely to be satisfied.

  For example, when the number of shifts of the predetermined shift is less than the fourth predetermined number of times, the control unit 34 determines that the fourth condition is satisfied. The fourth predetermined number of times is set in advance based on, for example, the relationship between the number of shifts of the predetermined shift and a general success rate regarding the shift. When the number of shifts of the predetermined shift is less than the fourth predetermined number of times, it is assumed that the success rate regarding the shift is high. That is, when the number of shifts of the predetermined shift is less than the fourth predetermined number of times, the degree of deterioration of the front derailleur TF, the rear derailleur TR, the planned shift front sprocket D1, the planned shift rear sprocket D2, and the chain D3 is low. Is assumed. In one example, the control unit 34 determines that the fourth condition is satisfied when the number of shifts of the first shift is less than the fourth predetermined number. Specifically, when the number of shifts of the first shift is less than the fourth predetermined number, the control unit 34 changes the shift conditions so that the shift condition for executing the first shift is easily established.

With reference to FIG. 6, an example of the control executed by the shift-related device 32 will be described.
In step S21, the control unit 34 acquires a shift history. Specifically, the control unit 34 receives a shift history from the detection device DD. In step S22, the control unit 34 notifies the notification information according to the shift history. In step S23, the control unit 34 determines whether or not the third condition is satisfied in the shift history. If the control unit 34 determines in step S23 that the third condition is satisfied in the shift history, the process proceeds to step S24. In step S24, the control unit 34 changes the speed change condition so that the speed change condition is less likely to be satisfied. On the other hand, when determining in step S23 that the third condition is not satisfied in the shift history, the control unit 34 proceeds to the process of step S25.

  In step S25, the control unit 34 determines whether or not the fourth condition is satisfied in the shift history. If the control unit 34 determines in step S25 that the fourth condition is not satisfied in the shift history, the process ends. Specifically, when it is determined that the third condition and the fourth condition are not satisfied in the shift history, the control unit 34 maintains the shift condition. On the other hand, if the control unit 34 determines in step S25 that the fourth condition is satisfied in the shift history, the process proceeds to step S26. In step S26, the control unit 34 changes the speed change condition so that the speed change condition is easily established. Through the above processing, the processing in steps S21 to S26 is completed. For example, the control unit 34 repeats the processes in steps S21 to S26 every predetermined time.
