Corresponding brain waves are stored in the database. Further, in order to reduce the erroneous judgment, the user 50 can be restricted to perform the shift thinking only in the limited option at a time, for example, the front shift or the rear must be considered first. After shifting, after determining the correctness, think about the increase or decrease.

(Judgment) Get the shift command? The central processing unit 11 determines whether the corresponding shift decision/command is found by the database, and if the result of the determination is that there is no user 50 brain wave no shift command, no shift information is displayed on the display unit 14, and vice versa. Go to the next step.

The servo motor is driven to perform shifting: the central processing unit 11 indirectly drives the servo motor 123 of the front shifting group or the rear shifting group to perform shifting.

(Judge) The speed change is successful? The central processing unit 11 determines whether the shift is completed according to the angle of the servo motor 123 feeding back its axis. If the shift fails, the display unit 14 or the light-emitting diode 17 displays the shift failure indicator number, for example, Red light output; otherwise, the next step is performed.

The shift completion command lamp number is displayed: the central processing unit 11 generates a display shift completion indicator number on the display unit 14 or the light emitting diode 17, for example, generates a green light output.

The delay is 2 seconds and waits for the shift command: the central processing module 11 is separated by two seconds, and the shift command is generated by the wireless signal analysis and judgment.

Based on the foregoing description, the present invention has the following features:

1. The user can control the shifting by brain wave to solve the technical problems that the prior art is inconvenient to use and may cause danger.

2. The position of the servo motor can be adjusted to produce a clutching effect with the shifting handle, so that the user can choose whether to automatically shift the brain wave.
