Fig. 2 is the high-mount brake lamp packet diagram among the present invention.
Fig. 3 is control logic figure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
The high-mount brake lamp control system of lighting like Fig. 1, classification shown in Figure 2; Comprise car body controller 1, abs controller 2, ESP controller 3, brake pedal K switch 1 and three groups of high-mount brake lamp, the BRAKE pin of car body controller 1 is connected with brake pedal K switch 1, obtains the pedal switch signal; The CAN-H of car body controller 1 and CAN-L pin and abs controller 2 are through the total wire joint of CAN; Obtain the ABS activation signal, the CAN-H of car body controller 1 and CAN-L pin also pass through the total wire joint of CAN with ESP controller 3, obtain the master brake cylinder pressure signal; The mouth of car body controller 1 is connected with three groups of high-mount brake lamp, is used to drive three groups of high-mount brake lamp classifications and lights.Three groups of high-mount brake lamp are respectively first group of high-mount brake lamp L1, second group of high-mount brake lamp L2 and the 3rd group of high-mount brake lamp L3; It is formed by resistance and light-emitting diode; First group of high-mount brake lamp L1 is positioned at midway location; Be second group of high-mount brake lamp L2, the 3rd group of high-mount brake lamp L3 then successively, the brightness of first group of high-mount brake lamp L1 is less than other brightness of two groups.
