Abstract
The invention discloses a brake lamp monitoring apparatus and a method using the monitoring apparatus for monitoring invalidation of brake lamps; the monitoring apparatus comprises a bodywork controller (7), a meter (8), a tappet switch (4), the brake lamps (5) and a rear fog lamp (6), wherein, the bodywork controller (7) is connected with a meter (9) by a bus and is used for detecting the state of the brake lamp (5); when one of the brake lamps is out of work, a brake fault indicating lamp arranged on the meter is caused to twinkle after the meter (8) receives the information. When the two brake lamps (5) are out of work at the same time, the fog lamp (6) is controlled to be lightened, and the brake fault indicating lamps on the meter (8) are simultaneously controlled to be lightened. The brake lamp monitoring apparatus can ensure the wiring to be simpler by adding a tail lamp driving module (9). By utilizing the technical proposal of the invention, the substitute proposal can be adopted after the self of the brake lamp has fault and is out of work; the brake lamp monitoring apparatus can automatically warn the succeeding vehicles, and simultaneously notice the driver that the brake lamps are out of work and need to be repaired as soon as possible by using the meter, thereby leading the drive to be safer.
Description
Technical field
The present invention relates to a kind of braking caution scheme, the particularly a kind of replacement scheme behind brake lamp fault.
Background technology
On the existing conventional truck, brake lamp is generally connected with brake switch, and the driver steps on brake pedal, and brake switch moves thereupon, lights brake lamp; Loosen the brake, brake switch resets, and brake lamp extinguishes.And in part advanced person's the vehicle that has bus system, can gather speed-slackening signal by vehicle body control unit, by bus speed-slackening signal is passed to lamp control unit, by lamp control unit drives brake lamp.
All there is a problem in these two kinds of schemes, and promptly when brake lamp itself broke down, brake lamp can't be lighted, and chaufeur and do not know that brake lamp lost efficacy.The front truck glancing impact, because of brakeless indicator lamp signal, back car driver can't be known front truck chaufeur braking intention, causes the generation of rear-end collision easily.
Summary of the invention
Main purpose of the present invention is exactly the problem that causes rear-end collision because of brake lamp fault in order to solve, a kind of chaufeur that do not rely on itself has been proposed, behind brake lamp fault, when chaufeur has braking maneuver, automatically light the technical scheme that substitutes light fixture, to reach the purpose of caution back car, can reduce the rear-end collision that causes because of brake lamp fault to the full extent.Concrete technical scheme is as follows.
A kind of brake lamp fault control monitor unit, comprise car body controller, instrument, brake switch, brake lamp and fog tail lamp is characterized in that: car body controller and instrument are by total wire joint, be used to detect the state of brake lamp, have at brake lamp under the situation of an inefficacy, after instrument receives information, make the brake fault indicator lamp flicker on it; Under two fail-all situations of brake lamp, the control fog lamp is lighted, and sends fail message to instrument simultaneously, and the brake fault indicator lamp of controlling on it is lighted.
Further, this control monitor unit also comprises a back light driver module, and this back light driver module is connected with car body controller and instrument by bus, detects, judges the brake lamp fault state voluntarily, and sends fail message to car body controller and instrument by bus.
The invention also discloses the method that adopts above-mentioned control monitor unit monitoring brake lamp fault.
The technical scheme of the application of the invention can adopt replacement scheme after brake lamp itself breaks down inefficacy, warn succeeding vehicle automatically, informs chaufeur by instrument simultaneously, and brake lamp lost efficacy, and maintenance as early as possible makes that driving is safer.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
Fig. 1 shows the first embodiment of the present invention, and shown brake lamp coutrol device mainly comprises: car body controller 7, instrument 8, ignition lock 2, storage battery 1, wire fuse 3, brake switch 4, brake lamp 5, fog tail lamp 6.Brake lamp 5 is by the car body controller direct control, and car body controller 7 passes through total wire joint with instrument 9.
Under normal condition, after ignition lock 2 is got to ON (opening) shelves, brake switch 4 actions, car body controller 7 is handled after collecting the signal of brake switch 4, drives brake lamp 5, and brake lamp 5 normal information are passed to instrument by bus.
Have at brake lamp under the situation of an inefficacy, car body controller detects this information, and this information is passed to instrument 8 by bus, after instrument 8 is learnt this information, with 1 hertz frequency the brake fault indicator lamp on the instrument 8 is glimmered, with the prompting chaufeur.
Second kind of situation is that two brake lamies lost efficacy entirely, car body controller 7 detects two fail-all information of lamp, this fail message is passed to instrument 8 by bus, after instrument is learnt this information, light the brake fault indicator lamp on the instrument, with alerting drivers, car body controller 7 control fog lamps are lighted simultaneously.
Fig. 2 shows the second embodiment of the present invention, has increased by a back light driver module 9 on the basis of first embodiment, and this back light driver module 9 is connected with car body controller 7 and instrument 8 by bus, judges the brake lamp fault state voluntarily.Concrete control is as follows.
Under normal condition, after ignition lock 2 is got to ON (opening) shelves, brake switch 7 actions, after car body controller 7 collects the signal of brake switch 4, this signal is converted to number signal, passes to back light driver module 9, after back light driver module 9 transforms the number of buses value signal by bus, drive brake lamp 5, and brake lamp 5 normal information are passed to instrument 8 by bus.
Have at brake lamp under the situation of an inefficacy, back light driver module 9 has detected lamp by drive current and had lost efficacy, and at this moment, 9 of back light driver modules pass to instrument 8 with this information by bus, and the flicker of control brake fault-indicating lamp is with the prompting chaufeur.
Under two fail-all situations of brake lamp, when back light driver module 9 detects two lamps and lost efficacy entirely by drive current, initiatively light fog tail lamp 6, send this fail message to instrument 8 by bus simultaneously, after instrument 8 receives this information, light the brake fault indicator lamp on the instrument, with alerting drivers.
The first embodiment of the present invention by car body controller directly detect, the control brake lamp, control is simple, but the wiring more complicated; The scheme of two embodiment has avoided a large amount of wire harness to connect by adopting back light driver module 9, has increased reliability.
