If the detection signal of the sensor assembly input controller is greater than 3V, the detection signal is high level, the controller judges that the initial state of the brake lever is abnormal, the controller judges that the brake lever of the vehicle is faulty, and sends fault information to the instrument to judge that the type of the brake lever is unmatched, so that the brake lever is erroneously installed, and the open brake lever is installed on the vehicle needing to be provided with the closed brake lever. Whether the handle of the brake lever is pulled or not is operated by factory staff or the user. The controller outputs fault information to the instrument to display fault codes, the brake handle fittings are reminded to be replaced, and the controller turns off the power supply of the motor driving module to achieve the purpose of fault judgment.

In the disconnected brake lever mode, if the brake lever is detected to be in a fault in an initial state. When the brake handle is not in work or is initially electrified, the controller detects low level, and at the moment, the controller sends out brake handle damage fault information to the instrument, so that on the one hand, the break-off brake handle can be judged to be damaged, and the break-off brake handle is always in a closed state due to damage. When the brake handle is not in operation, the controller detects a high-level signal, and then the controller sends out a brake handle damage fault to the instrument, and the fault type is open circuit output of the brake handle sensor.
The brake lever working state detection in the step S4 comprises the following steps:
in the disconnected brake lever mode, after the handle of the brake lever is pulled, the sensor assembly sends a detection signal to the controller;
