Description
Technical field
The utility model belongs to the automobile brake technical field, specially refers to the brake lamp coutrol device of automobile.
Background technology
The brake lamp of automobile has the function that warning front vehicle front vehicles is being braked.Conventional brake lamp is once all to light after chaufeur is stepped on brake pedal, the problem of Cun Zaiing is like this, when the chaufeur of front vehicle sees that the front vehicles brake lamp is lighted, front vehicles has been implemented braking, the speed of a motor vehicle that is front vehicles obviously descends, and the rear vehicle is often because the speed of a motor vehicle is too fast or following distance too closely causes emergency stopping distance not enough, the generation rear-end collision, especially on than dark situation and expressway, more be prone to accidents.Therefore need a kind of vehicle forwardly that the braking intention is arranged, but do not implement the device that glancing impact can be reminded the front vehicle chaufeur, to guarantee traffic safety.
The utility model content
The purpose of this utility model is to propose a kind ofly can to shift to an earlier date the brake lamp coutrol device of vehicle early warning rearward.
Brake lamp coutrol device of the present utility model comprises brake lamp, brake pedal switch and receives the control unit of the signal of brake pedal switch with control brake lamp state, key is that described control unit also is connected with the acceleration pedal switch, and described brake lamp has at least two kinds of luminance states or comprises the bulb that two or more can independently be controlled by control unit.
The control principle of above-mentioned brake lamp coutrol device is as follows: the acceleration pedal switch can send to the different signal of control unit according to the state of stepping on of acceleration pedal, the brake pedal switch can send to the different signal of control unit according to the state of stepping on of brake pedal, after the acceleration pedal switch sends the signal of " acceleration pedal is not stepped on " to control unit, just represent that chaufeur may take brake measure, this moment, control unit will be lighted the bulb of a part of brake lamp, perhaps brake lamp is all lighted, but brightness is lower; After the brake pedal switch sends the signal of " brake pedal is stepped on " to control unit, just represent that chaufeur taked brake measure, this moment, control unit will be lighted whole bulbs of brake lamp, perhaps brake lamp is all lighted, and brightness is turned up full blast.So just realized that rearward vehicle sends the function of early warning in advance when chaufeur has the braking intention but do not implement brake measure, given reaction time and the car brakeing time of the chaufeur of front vehicle, guaranteed traffic safety with abundance.
The circuit of brake lamp coutrol device can followingly be provided with: described brake lamp comprises the bulb of two groups of parallel connections, wherein the positive pole of one group of bulb links to each other with first output pin of control unit, positive pole of another group bulb links to each other with second output pin of control unit, links to each other by diode between first output pin of control unit and second output pin; The negative pole of two groups of bulbs links to each other.Control unit can be controlled the output of first output pin and second output pin according to received signal, because the unidirectional conducting effect of diode, make and to light coupled brake lamp bulb group with diode cathode end bonded assembly output pin, and can light whole brake lamp bulb groups with diode cathode end bonded assembly output pin, so just realized the purpose of two groups of bulb groups of independent control.
Because the high-mount brake lamp of present most of car has all adopted led light source, life-span is longer than the life-span of conventional light source, therefore preferably be installed in the high-mount brake lamp of automobile with diode cathode end bonded assembly bulb group, even it is more frequent to implement the bulb group on-off ratio of forewarning function like this, also can guarantee certain service life.
The circuit of brake lamp coutrol device can also following setting: described brake lamp is the bulb of one group of parallel connection, and the positive pole of bulb group links to each other with the mouth of a power amplification circuit, and the control end of described power amplification circuit links to each other with the mouth of control unit.The signal that the control unit basis receives is controlled the voltage of its output pin, and the voltage of this output pin amplifies the brightness of control brake lamp afterwards through power amplification circuit, and the realization secondary is lighted.
Brake lamp coutrol device of the present utility model is simple in structure, cost is low, only needing increases an acceleration pedal switch, can realize warning function under the effect of control unit software, and technology maturation is reliable, can effectively reduce the probability of occurrence of rear-end collision, improve traveling security.
Description of drawings
Fig. 1 is the schematic diagram of the brake lamp coutrol device of embodiment 1;
Fig. 2 is the schematic diagram of the brake lamp coutrol device of embodiment 2.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, the brake lamp coutrol device of present embodiment comprises brake lamp 1, the signal of brake pedal switch 2 and reception brake pedal switch 2 is with the control unit 3 of control brake lamp 1 state, control unit 3 also is connected with acceleration pedal switch 4, brake lamp 1 comprises the bulb 11 of two groups of parallel connections, 12, wherein the positive pole of bulb group 12 links to each other with first output pin of control unit 3, the positive pole of bulb group 11 links to each other with second output pin of control unit 3, link to each other by diode 5 between first output pin of control unit and second output pin, wherein first output pin of control unit links to each other with the positive pole of diode 5, and wherein second output pin of control unit links to each other with the negative pole of diode 5; The negative pole of two groups of bulbs 11,12 links to each other by current-limiting resistance.
Because the high-mount brake lamp of present most of car has all adopted led light source, life-span is longer than the life-span of conventional light source, therefore be installed in the high-mount brake lamp of automobile with diode 5 negative pole end bonded assembly bulb groups 11, even it is more frequent to implement bulb group 11 on-off ratios of forewarning function like this, also can guarantee certain service life.
Specifically, after acceleration pedal switch 4 sends the signal of " acceleration pedal is not stepped on " to control unit 3, just represent that chaufeur may take brake measure, this moment, control unit 3 was just exported high level to second output pin, lighted bulb group 11; After brake pedal switch 2 sends the signal of " brake pedal is stepped on " to control unit 3, just represent that chaufeur taked brake measure, this moment, control unit 3 was just to first output pin output high level, when lighting bulb group 12, the electric current of first output pin also can be lighted bulb group 11 through diode 5, thereby lights whole bulbs of brake lamp 1.
