Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
As shown in the figure, the car lamp control system of the present invention, including the main control end control with automobile controller communication connection
Device processed is correspondingly arranged at the controlled side controller being connect in vehicle lamp assembly and controllably with each car light, the controlled side controller
It is connect by a single data bus with the main control end controller communication, the master control side controller and controlled side controller
It is directly powered by cathode power supply line respectively.
The car lamp control system of the present invention sets controlled side controller in each vehicle lamp assembly, and utilizes a radical
Its communication with master control side controller is realized according to line, and along with a cathode power supply line, each vehicle lamp assembly only needs assembling two
Line, the carry out control mode of a single data bus also reduce the length of data line, greatly reduce making for harness on the whole
With, assembling and material cost are reduced,
Specifically, it is to realize that controlled side controller controls the switch of each car light, car light L1-L5's as described in Figure 3
The relay U1-U5 by being controlled side controller control is serially connected on circuit respectively, meanwhile, to improve the feedback to switch control,
It is provided on each circuit of the car light, on the part or all of circuit of the vehicle lamp assembly and is controlled with corresponding controlled terminal
The sensor of device communication, e.g., the sensor are Phototube Coupling sensor.Specifically, described car light L1-L5 one end with just
A pair of contact connection of the pole power cord through relay, the other end is grounded after resistance R4 or R7 or R10 or R13 or R16, described
Sensor is set with the resistor coupled in parallel.The signal feedback end of the sensor corresponds to the controlled side controller of access.
Phototube Coupling sensor is directly attempted by the circuit of car light, then after the car light is lit, photoisolator energy
To controlled side controller feedback signal, direct feedback mechanism is introduced between side controller and car light controlled, can ensure that car light by reality
I.e. actual power is really lighted on border, increases the validity to master control side controller feedback information.
Moreover, as shown in Fig. 2, for further control cost, it can also be by each car light or part vehicle of a vehicle lamp assembly
The circuit of lamp is simultaneously connected to same photoisolator, and the feedback of multiple car lights is realized using each photoisolator, is effectively controlled
This and space hold is made.
Further, other forms also can be used in the sensor, such as can also be into the combination or replacement of line sensor
It uses, e.g., increases light intensity sensor or the temperature sensor that is arranged on car light near of the detection faces in car light side, pass through
The variation of light intensity or temperature is detected, it equally can be to the controlled bright effect of side controller feedback point.
The use of the sensor is applied in combination, and effectively avoids ambient, such as the influence of sunlight or opposite car light,
Prevent to judge by accident, improve feedback authenticity.
Further, vehicle lamp assembly, such as left front car light, right front car light and rear vehicle lamp are made into assembly, i.e. mould respectively
Block, chip and headstock are fitted together, and there was only circuit and interface on car body, and vehicle lamp assembly carries chip and relay switch etc.,
It is directly installed on the interface on vehicle body and assembling can be completed.
As better embodiment, the smoke sensor device being connect with the main control end controller communication is further included, it is described
Smoke sensor device be arranged in forward engine room lid.
By increasing smoke sensor device, the accidents such as spontaneous combustion are can effectively prevent, when there is smog, master control side controller carries out
Active car light, which is warned, gives him vehicle, creates conditions to car owner's parking and follow-up flee from, can also reduce secondary disaster, meanwhile, can also it lead to
Interior warning light is crossed to warn, such as pass through supersound projector or disposable alarm.
The control method of automobile lamp of the present invention, includes the following steps,
1) master control side controller receives the car light control signal that automobile controller is sent out and passes through single data bus transmission
Control instruction, the control instruction include car light address and control mode in vehicle lamp assembly address, assembly, the controlling party
Formula is is turned on and off；
2) the controlled side controller of each vehicle lamp assembly receives the control instruction and parses, and if address mismatches, then abandons,
The controlled side controller performs the control to the car light specified in control instruction if address matching；
3) the controlled terminal controller monitoring data bus status of output car light control, by data/address bus to master control when idle
Side controller sends feedback information；
4) master control side controller receives feedback information then the control terminates, if in the given time to receive feedback, into
Row is warned.
The control of the present invention is carried out data transmission, for car light using a bus-control method in the form of broadcast
For control, best control effect can be fully achieved, moreover, introducing feedback mechanism in control, the reality to car light can be improved
Border control effect is reduced because of unexpected even traffic accident caused by car light control is not smooth.Wherein master control side controller and controlled terminal control
Communication between system is transmitted using predetermined protocol, and transmission speed is fast, and data accuracy is high, and parsing is quick, improves the steady of operation
It is qualitative, and according to setting priority, master control side controller sends the priority that priority is higher than controlled side controller feedback, protects
Card control transmission is normally carried out.
Specifically, it further includes to sense by sensor in the step 3) and be controlled again to main control end after car light is lighted
Device sends the step of feedback information, is lighted if cannot car light normally be sensed, and does not send feedback information or sends fault message.
The sensor includes photoisolator, photosensitive sensors and/or the temperature sensor series connection in the loop.It is and described
Step 4) in do not receive feedback signal, then master control side controller can repeat to send pre-determined number, such as the control instruction of 3-5 times,
Then feedback information is not received yet to warn again.
By establishing reliablely and stablely communication modes, the control for waiting for and repeating is added in, effectively information can be avoided to pass
False alarm caused by passing error improves the fault-tolerance of system.
Moreover, the control method of the present invention is further included after receiving smog alarm information, actively controlled by main side side controller
The car light for making each vehicle lamp assembly lights the step of being alarmed, wherein being may also include while lighting to directly exporting to lock solution
Lock or to automobile middle control send out unlock instruction the step of, the contiguity constraint as possible in this way when electric component can also work avoids
Because damage by fire electrical equipment causes order that cannot perform effectively the possibility for leading to secondary disaster.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
