[0030] Preferably, the control module 1 is a single-chip microcomputer or MCU.

[0031] Preferably, the power detection module 6 includes a voltage detection unit 61, which is used to collect the voltages of the motor controller, the power assist sensor, the gyroscope, and the wheel speed sensor, and transmit the collected voltage signals to the control module 1.

The control module 1 analyzes the operating current performance of the motor controller based on the received current signal.

[0033] Preferably, the system further includes a mode detection module 7 electrically connected to the control module 1. The mode detection module 7 includes a combined mode detection unit 71 and a single mode detection unit 72. The combined mode detection unit 71 is used to detect the integrated mode of the motor controller and the motor, and to send a first command to the assist sensor detection module 3, the gyroscope detection module 4, the wheel speed sensor detection module 5, and the power detection module 6. The single mode detection unit 72 is used to detect a single motor controller, and to send a second command to the assist sensor detection module 3, the gyroscope detection module 4, the wheel speed sensor detection module 5, and the power detection module 6.

Control module 1 analyzes and judges the received feedback signals.

[0037] The control module 1 has preset performance information for the current motor controller. When the feedback signal received by the control module 1 does not match the preset performance information, the control mode detection module 7 of the control module 1 sends a second command to the assist sensor detection module 3, gyroscope detection module 4, wheel speed sensor detection module 5, and power detection module 6.
