In this case, the control section 68 may shift from the first control state to the second control state. For example, when the component 40 is the friction member 40A, the controller 68 controls the motor of the drive unit 34 so that the assist force of the drive unit 34 is smaller in the second control state than in the first control state. In this case, since at least one of the frequency of braking and the intensity of operation by the braking device 42 can be reduced, wear of the friction member 40A can be suppressed.

When power is supplied to the artificial intelligence processing unit 64, the control unit 68 starts processing and proceeds to step S21 of the flowchart shown in FIG.

In step S21, the control unit 68 determines whether or not it is in the first control state. If the control unit 68 is not in the first control state, the process ends. In the case of the first control state, the control section 68 proceeds to step S22.

In step S22, the control unit 68 determines whether the component 40 is in the second deteriorated state or the second worn state. If the component 40 is not in the second state of deterioration or the second state of wear, the process ends. If the component 40 is in the second deteriorated state or the second worn state, the controller 68 proceeds to step S23. In step S23, the control unit 68 transitions to the second control state and ends the process. Until the power supply is stopped, the control unit 68 proceeds to step S21 after a predetermined cycle has elapsed after the flow chart shown in FIG. 4 is completed.

The control unit 68 may shift from the second control state to the first control state by operating the operating device 46, an external device, or the like.
