When the vehicle 200 is in a stop state, if the moment is attenuated to be less than 90% of the standard moment, the vehicle 200 can inform the vehicle owner of a phone and a short message through the internet of things, and the vehicle 200 can give a buzzer alarm at the same time, so that other parts of the vehicle 200 are prevented from being stolen.

In the embodiment of the present application, the torque detection bolt 100 may be assembled first, and then the torque detection bolt 100 may be mounted on the wheel.

In step S21, when the vehicle 200 is in a running state and the torque of the torque detection bolt 100 of the vehicle 200 is rapidly attenuated to less than 80% of the standard torque, the control system of the vehicle 200 determines that the vehicle 200 needs maintenance, and the warning and detection can be canceled through the maintenance mode of the display screen, but the function is automatically recovered after the maintenance. When the control system cannot acquire the signal, the signal is determined to be lost, the control system can be reflected to an instrument panel or a display screen, and the vehicle owner can be notified of the telephone and the short message through the Internet of things.
