Problems solved by technology
The invention discloses a brake lamp sensor, and relates to the technical field of automobile manufacturing. The brake lamp sensor comprises two power source processing circuits, one is a first powersource processing circuit and the other is a second power source processing circuit, the first power source processing circuit provides a working power source for a first Hall element, the second power source processing circuit provides a working power source for a second Hall element, the output end of the first Hall element outputs a signal through a first switch tube, and the output end of thesecond Hall element outputs a signal through a second switch tube; and the first switch tube acquires a power source from the first power source processing circuit, and the second switch tube acquiresa power source from the second power source processing circuit. According to the brake lamp sensor, the problem that in the prior art, one path of power is powered down, then the two paths of signalsof BLS and BTS are lost, and the driving safety is influenced can be solved.
