Abstract
The invention relates to a method and a device for monitoring faults of a vehicle lamp, which can realize the effective monitoring of vehicle lamp faults. The invention adopts the technical scheme that the method for monitoring the faults of the vehicle lamp is characterized in that a vehicle lamp switch is connected with a master controller; when the switch is closed, the master controller drivesthe vehicle lamp to be turned on; and when a fault of the vehicle lamp occurs, the master controller controls the twinkling of an indication lamp through a CAN bus control instrument to alarm.
Description
Technical field
The present invention relates to a kind of fault monitoring method and device of automobile lamp.
Background technology
The existing various marker lamps of automobile do not have fault display device, various marker lamps (steering indicating light, stoplight stop lamp, backing-up lamp, registration mark light, position lamp, flank indicator etc.) whether check to dress lamp place by normal need, if having the assistant just need get on or off the bus, the driver do not check back and forth, comparatively trouble.
If marker lamp damages or electric leakage or short circuit phenomenon appear in the marker lamp circuit when driving, the driver is in operator's compartment and do not know, is easy to take place traffic accident, and may damages the electric power system on the car.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of fault monitoring method and device of automobile lamp, can realize the effective monitoring to the automobile lamp fault.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of fault monitoring method of automobile lamp, it is characterized in that: lighting switch connects master controller, and during switch closure, master controller drives car light and opens, and when car light broke down, master controller was reported to the police by the flicker of CAN bus control instrument indicator lamp.
When the car light normal operation, master controller is lighted meter lamp by the CAN bus.
Master controller judges by monitoring car light loop current whether car light breaks down.
Master controller can be car body controller BCM.
2, a kind of device of realizing the fault monitoring method of aforementioned automobile lamp, it is characterized in that: lighting switch connects master controller, and master controller is by CAN bus interface instrument.
Master controller can be car body controller BCM.
Master controller can be monitored the vehicle light circuit electric current.
The beneficial effect that the present invention has:
The present invention can realize effectively monitoring to automobile lamp.During the car light normal operation, the LED light Chang Liang on the instrument, when the car loop short circuit appears, when abnormal condition such as opening circuit, the indicator lamp on the instrument glimmers immediately, with prompting chaufeur headlight job failure, needs maintenance, can effectively strengthen the safety of vehicle drive.Simultaneously, circuit structure of the present invention is simple, and cost is low, and it is convenient to implement.
Description of drawings
Accompanying drawing is schematic circuit diagram of the present invention.
The specific embodiment
As shown in the figure, lighting switch 1 connects master controller 2, and master controller connects instrument 4 by CAN bus 5.Master controller can be car body controller BCM, and master controller can be monitored the vehicle light circuit electric current.
During switch 1 closure, master controller drives car light 3 and opens, and when the car light normal operation, master controller 2 is lighted meter lamp by CAN bus 5.When car light breaks down, during vehicle light circuit electric current generation ANOMALOUS VARIATIONS, master controller 2 outputs signal to instrument by CAN bus 5, and the meter lamp flicker is reported to the police.
Claims (7)
1, a kind of fault monitoring method of automobile lamp, it is characterized in that: lighting switch connects master controller, and during switch closure, master controller drives car light and opens, and when car light broke down, master controller was reported to the police by the flicker of CAN bus control instrument indicator lamp.
2, the fault monitoring method of automobile lamp according to claim 1 is characterized in that: when the car light normal operation, master controller is lighted meter lamp by the CAN bus.
3, the fault monitoring method of automobile lamp according to claim 2 is characterized in that: master controller judges by monitoring car light loop current whether car light breaks down.
4, the fault monitoring method of automobile lamp according to claim 3 is characterized in that: master controller can be car body controller BCM.
5, a kind of device of realizing the described automobile lamp fault monitoring method of claim 1, it is characterized in that: lighting switch connects master controller, and master controller is by CAN bus interface instrument.
6, automobile lamp fault monitoring device according to claim 5 is characterized in that: master controller can be car body controller BCM.
7, automobile lamp fault monitoring device according to claim 6 is characterized in that: master controller can be monitored the vehicle light circuit electric current.
