Abstract
The invention aims at providing a brake lamp detection and breakdown alternative method to reduce the occurrence of rear-end collision accidents and improve safety of driving. According to steps of the brake lamp detection and breakdown alternative method, after a brake pedal is stepped on, a lighting control unit module detects working conditions of each brake lamp; when breakdowns occur to the brake lamps, the lighting control unit module controls width lamps at the back of a car to light to replace brake lamps to give a warning. When breakdowns occur to the brake lamps, the lighting control unit module sends message to an automobile body controller, and the automobile body controller controls an alarm display device to give out an alarm to remind people to repair the brake lamps as early as possible and to remove potential safety hazards. Due to the fact that the positions of the width lamps are close to the brake lamps, from the angle of a rear car, the width lamps are mistaken as the brake lamps easily. Therefore, lighting of the width lamps gives a braking signal to the rear car, and occurrence of the rear-end collision accidents is reduced.
Description
Technical field
The present invention relates to a kind of brake lamp detects and the fault alternative method.
Background technology
Orthodox car all is to adopt chaufeur to step on brake pedal, and the control travel switch is connected brake lamp, lights bulb or LED lamp; Loosen the brake breaks off brake lamp, extinguishes bulb or LED lamp.And some medium-to-high grade automobile has adopted lighting control unit module controls car load Lighting System, and gives relevant demonstration, panalarm through the bus system transmission signals.These two kinds of control policies have a drawback: chaufeur is not known the brake lamp fault in braking procedure, and therefore the back vehicle can't be known the braking intention of front truck through the brake lamp of front truck, finds rear-end collision easily.This in addition fault chaufeur when the capable inspection of driving precedent also is difficult to find.
Summary of the invention
The objective of the invention is to propose a kind of brake lamp and detect and the fault alternative method,, improve travel safety to reduce the generation of rear-end collision.
Brake lamp of the present invention detects and the fault alternative method comprises the steps: after brake pedal is stepped on; The lighting control unit module detects the service condition of each brake lamp; If brake lamp breaks down; Then the side-marker lamp of lighting control unit module controls automobile rear lights, and warns to replace brake lamp.Because side-marker lamp's position is very approaching with brake lamp, the angle at the back car is easy to think brake lamp to the side-marker lamp, therefore lights the side-marker lamp, can give the signal of a braking of back car, thereby reduces the generation of rear-end collision.
Further, after brake lamp broke down, lighting control unit module photos and sending messages was given car body controller, and car body controller control alarm display device is reported to the police, and as early as possible brake lamp is keeped in repair with reminds people, removes potential safety hazard.
Further, when brake pedal was stepped on, the side-marker lamp of automobile rear lighted, and the brake lamp et out of order, and the then side-marker lamp of lighting control unit module controls automobile rear flicker is warned to replace brake lamp.Even when driving a vehicle night, brake the signal of warning clearly also can for one in back car like this, further improve travel safety.
Specifically, if left brake lamp breaks down, then the left side-marker lamp of lighting control unit module controls automobile rear lights; If right brake lamp breaks down, then the right side-marker lamp of lighting control unit module controls automobile rear lights; If high-mount brake lamp breaks down, then the left and right side-marker lamp of lighting control unit module controls automobile rear lights simultaneously.
Perhaps if left brake lamp breaks down, then the left side-marker lamp of lighting control unit module controls automobile rear is glimmered; If right brake lamp breaks down, then right side-marker lamp's flicker of lighting control unit module controls automobile rear; If high-mount brake lamp breaks down, then the left and right side-marker lamp of lighting control unit module controls automobile rear is glimmered simultaneously.
Further, the lighting control unit module detects the service condition of brake lamp through the working current that detects each brake lamp, if the working current of certain brake lamp is during less than its running current, then the lighting control unit module judges that this brake lamp breaks down.
Further, said when having only working current when certain brake lamp less than predetermined current value, the lighting control unit module judges that just this brake lamp breaks down; Said predetermined current value is less than the running current of brake lamp.Like this can be just can be because of bulb is not aging, internal resistance becomes (this moment, brake lamp still can be lighted) when causing the real work electric current less than normal greatly, mistake is judged as the brake lamp fault, thereby reduces false alarm rate,
Brake lamp of the present invention detects and the fault alternative method not only can make chaufeur in time learn the brake lamp failure condition; Can also utilize the side-marker lamp to substitute the brake lamp of fault temporarily; Warning the back car, thereby reduce the probability of occurrence of rear-end collision, improved travel safety.
The specific embodiment
Below through to the description of embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are done further to specify.
Embodiment 1:
The brake lamp of present embodiment detects and the fault alternative method comprises the steps:
After brake pedal is stepped on; The lighting control unit module detects the service condition of brake lamp through the working current that detects each brake lamp; If the working current of certain brake lamp is during less than predetermined current value, the lighting control unit module judges that this brake lamp breaks down; Said predetermined current value is less than the running current of brake lamp;
If left brake lamp breaks down, then the left side-marker lamp of lighting control unit module controls automobile rear lights; If right brake lamp breaks down, then the right side-marker lamp of lighting control unit module controls automobile rear lights; If high-mount brake lamp breaks down, then the left and right side-marker lamp of lighting control unit module controls automobile rear lights simultaneously; So just can utilize the side-marker lamp to replace brake lamp to warn;
After brake lamp broke down, lighting control unit module photos and sending messages was given car body controller, and car body controller control alarm display device is reported to the police, and as early as possible brake lamp is keeped in repair with reminds people, removes potential safety hazard.
If when brake pedal is stepped on, the side-marker lamp of automobile rear lights, and the brake lamp et out of order, and the then side-marker lamp of lighting control unit module controls automobile rear flicker is warned to replace brake lamp.Specifically, if left brake lamp breaks down, then left side-marker lamp's flicker of lighting control unit module controls automobile rear; If right brake lamp breaks down, then right side-marker lamp's flicker of lighting control unit module controls automobile rear; If high-mount brake lamp breaks down, then the left and right side-marker lamp of lighting control unit module controls automobile rear is glimmered simultaneously.
