In the preferred embodiment, the driving computer 311 of the vehicle 31 is a body control module (BCM), and can be controlled to be installed in the vehicle. The electronic component of 31 has a busbar to provide electrical control and control for other controllers, such as the automotive brake warning device disclosed in the preferred embodiment.

The signal information output port 331, the speed information input port 332, the angle information input port 333, the power source input port 334, and the rear information input port 335 are electrodes having screws for fixing wires and transmitting information to the The brake early warning control module 322 may also output the brake early warning control module 322 to the outside. The technology for fixing the electric wire to the electrode is a conventional technique and will not be described in detail herein.

The signal information output port 331 is electrically connected to the driving computer 311 by using a wire; the speed information input port 332 provides the speed detecting module 341 for electrical connection; the angle information input port 333 provides the angle detecting module 342. The power input port 334 is electrically connected to the power source of the vehicle 31 by using a wire; the rear information input port 335 provides electrical connection of the rear detecting module 343.
