Referring to fig. 1, in the present embodiment, the braking system includes a first position sensor 100, a regulated voltage source 200, and a second position sensor 300. The first position sensor 100 transmits a wake-up signal when it detects that the pedal 400 is spaced apart from the original position by a distance greater than a set wake-up distance, and the magnet 410 is fixed to the pedal 400. The regulated voltage source 200 is connected to the first position sensor 100 and outputs a supply voltage according to the wake-up signal. The second position sensor 300 is connected to the regulated voltage source 200 and receives the power supply voltage to begin detecting movement of the pedal 400.

Specifically, when the driver steps on the pedal 400, the first position sensor 100 detects the movement of the pedal 400, and transmits a wake-up signal when detecting that the pedal 400 is more than a set wake-up distance away from the original position. The regulated voltage source 200 receives the wake-up signal and enters the wake-up state from the sleep state and outputs a power supply voltage. The second position sensor 300 receives a power supply voltage and enters a wake-up state from a sleep state and starts to detect the movement of the pedal 400. In contrast, when the driver stops stepping on the pedal 400, the first position sensor 100 transmits the sleep signal when detecting that the pedal 400 is not more than the set wake-up distance from the original position. The regulated voltage source 200 receives the sleep signal and enters the sleep state from the wake-up state and stops outputting the power supply voltage. The second position sensor 300 does not receive the power voltage to enter the sleep state from the awake state and stops detecting the movement of the pedal 400.

Therefore, the braking system of the embodiment can enable the stable voltage source 200 and the second position sensor 300 to enter the wake-up state from the sleep state only when the pedal 400 is stepped on, so that the loss of electric energy is reduced.

In one embodiment, the first position sensor 100 is a hall switch sensor and the pedal 400 has a magnet 410 fixed thereto. According to the hall effect, the hall circuit generates corresponding hall voltages when the magnet 410 is at different positions, and the first position sensor 100 can output according to the position of the magnet 410 on the pedal 400, for example, when the magnet 410 is away from the original position following the pedal 400 by more than a set wake-up distance, the first position sensor 100 outputs a wake-up signal, for example, a high level signal. In one embodiment, the magnet 410 is fixed to the top bar of the pedal 400.

In an embodiment, the regulated voltage source 200 may be connected to a vehicle battery, and may receive a voltage of the vehicle battery according to the wake-up signal.

In one embodiment, the second position sensor 300 may be a photo sensor, an infrared sensor, a hall sensor, or the like, to perform non-contact position detection.

This brake switch module 500 makes stop lamp 600 get into dormancy according to the stop lamp turn-on signal and awakens up, reaches the low-power consumption effect, and because of not mechanical brake switch, has avoided contact failure that mechanical strain etc. come. In one embodiment, the brake switch modules 500 may be two for the turning on of two brake lights 600, respectively.

In one embodiment, the stop lamp turn-on signal may be a high-side driving signal, i.e., the turn-on of the stop lamp 600 is achieved by closing a switch on a power line directly on the circuit of the stop lamp 600.

In an embodiment, as shown in fig. 1, the braking system further includes a CAN transceiver 700, the CAN transceiver 700 is respectively connected to the second position sensor 300 and an on-board computer 800 (ECU), the second position sensor 300 sends the moving position information of the pedal 400 to the on-board computer 800 through the CAN transceiver 700, so that the on-board computer 800 CAN send out a warning prompt tone to remind pedestrians outside the vehicle.
