Embodiment 1
[0018] An automatic fault detection system for automobile brake lights according to the present invention, comprising: left and right brake light detection modules, the left and right brake light detection modules are suitable for detecting and responding to the operation of the left and right brake lights when the brakes are stepped on state.
[0019] Such as figure 1 As shown, the circuit structures of the left and right brake light detection modules are the same and both include: a current detection circuit for detecting the working current of the brake light, a voltage comparison circuit connected to the current detection circuit, and the voltage comparison circuit detects the current The output level of the circuit is compared with the reference voltage to obtain the fault judgment level, and the fault judgment level is connected to the fault display circuit to reflect the working status of the left and right brake lights.
[0020] Such as figure 2 As shown, specifical...
Embodiment 2
[0024] On the basis of Embodiment 1, the present invention also provides a working method of an automatic detection system for brake light failures of automobiles.
[0025] Wherein, the automatic detection system for automobile brake light failure includes: left and right brake light detection modules,
[0026] When the brake is stepped on, the left and right brake light detection modules are adapted to detect and respond to the working status of the left and right brake lights.
[0027] Further, the circuit structures of the left and right brake light detection modules are the same, and both include: a current detection circuit for detecting the working current of the brake light, a voltage comparison circuit connected to the current detection circuit, and the voltage comparison circuit. The output level is compared with the reference voltage to obtain the fault judgment level, and the fault judgment level is connected to the fault display circuit to reflect the working statu...
