Abstract
This utility model relates to vehicle electric field, particularly relate to a kind of intelligent controller for automobile brake lamp, including CAN transceiver, microcontroller and driver, CAN transceiver receives the automobile brake signal in CAN and GES, microcontroller is when receiving CAN transceiver and transmitting the automobile brake signal come, it is poor that microcontroller transmits the GES calculating speed come according to CAN transceiver, automobile brake signal is carried out classification according to the speed difference calculated by microcontroller, microcontroller controls the output of driver according to the rank of automobile brake signal, automobile brake lamp is connected with driver.Automobile is taked speed difference during braking to judge indicating brake action by microcontroller by this utility model, rear car has only to observe the flashing state of front truck automobile brake lamp and just can draw front truck indicating brake action thus take appropriate measures, the safety of the driving being greatly improved.
Description
Technical field
This utility model relates to vehicle electric field, particularly relates to a kind of intelligent controller for automobile brake lamp.
Background technology
At present in automobile, as long as taking brake measure, automobile brake lamp all can light, to warn rear car.But automobilism
During, due to front road conditions problem or occur emergency case time, front truck carries out brake hard, but rear car cannot be according to front
The dynamics that the condition discrimination of car Brake lamp is now braked, can only judge that the distance of vehicle changes by naked eyes, easily cause wind such as knocking into the back
Danger.
Utility model content
The purpose of this utility model is the defect overcoming prior art to exist, it is provided that a kind of rear car is braked by observing front truck
Lamp flashing state judges the intelligent controller for automobile brake lamp of front truck indicating brake action.
The technical scheme realizing this utility model purpose is: a kind of intelligent controller for automobile brake lamp, including CAN
Transceiver, microcontroller and driver, CAN transceiver receives the automobile brake signal in CAN and GES, microcontroller
Device is when receiving CAN transceiver and transmitting the automobile brake signal come, and microcontroller transmits the speed letter come according to CAN transceiver
Number calculate speed poor, microcontroller according to calculating speed difference automobile brake signal is carried out classification, microcontroller is according to automobile
The rank of brake signal controls the output of driver, and automobile brake lamp is connected with driver.
As prioritization scheme of the present utility model, driver exports constant current to automobile brake lamp, and automobile brake lamp is normal
Bright.
As prioritization scheme of the present utility model, driver exports pwm pulse signal, automobile brake lamp to automobile brake lamp
Flicker.
As prioritization scheme of the present utility model, the flicker frequency of automobile brake lamp is entered according to the rank of automobile brake signal
Row regulation.
This utility model has a positive effect: automobile is taked speed during braking by microcontroller by this utility model
Difference judge indicating brake action, rear car have only to observe front truck automobile brake lamp flashing state just can draw front truck indicating brake action
Thus take appropriate measures, the safety of the driving being greatly improved.
Accompanying drawing explanation
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail this utility model, wherein:
Fig. 1 is theory diagram of the present utility model.
Wherein, 1, CAN transceiver, 2, microcontroller, 3, driver, 4, automobile brake lamp.
Detailed description of the invention
As it is shown in figure 1, the utility model discloses a kind of intelligent controller for automobile brake lamp, receive and dispatch including CAN
Device 1, microcontroller 2 and driver 3, CAN transceiver 1 receives the automobile brake signal in CAN and GES, microcontroller
Device 2 is when receiving CAN transceiver 1 and transmitting the automobile brake signal come, and microcontroller 2 transmits, according to CAN transceiver 1, the car of coming
It is poor that speed signal calculates speed, and automobile brake signal is carried out classification, microcontroller 2 according to the speed difference of calculating by microcontroller 2
Control the output of driver 3 according to the rank of automobile brake signal, automobile brake lamp 4 is connected with driver 3.Automobile brake is believed
Number the rank i.e. dynamics of automobile brake, speed difference is the biggest, and indicating brake action is the biggest, and speed difference is the least, and indicating brake action is the least.
When the speed difference that microcontroller 2 calculates is less than certain limit value, driver 3 exports constant current to automobile brake lamp 4,
Automobile brake lamp 4 Chang Liang.
When the speed difference that microcontroller 2 calculates is more than certain limit value, driver 3 exports PWM (Pulse to automobile brake lamp 4
Width Modulation pulse width modulation) pulse signal, automobile brake lamp 4 flashes.Wherein, the limit value of speed difference is according to reality
Test and choose with experience.The flicker frequency of automobile brake lamp 4 is adjusted according to the rank of automobile brake signal, and brake force is relatively
Hour, automobile brake lamp 4 Chang Liang, along with the increase of indicating brake action, the flicker frequency of automobile brake lamp 4 is accelerated, thus effectively
Warning rear car.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
Step describes in detail, be it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, all should wrap
Within being contained in protection domain of the present utility model.
