Further technical characterictic, described microprocessor comprise power module, protection module, vehicle processing module, illumination analysis module, manual identification module, automatic processing module and output module.

With respect to prior art, the utlity model has following remarkable advantage:

1, can satisfy the demand of various vehicles, range of use is greatly expanded.Be provided with the various open modes of lampet, low beam and lamp far away in the vehicle preset device, possess the positive negative control of independently overtaking other vehicles, two lamp systems and four lamp systems output control, 432 kinds of different car bulb open modes can be provided;

2, by microprocessor manual identification module hand signal is discerned, and realized automatically and manually operated is controlled simultaneously by the manual identification circuit, need not conversion, broken the traditional pattern that manually and automatically can only select one, convenient chaufeur is tackled various complex situations, has reduced the traffic accident incidence;

3, the installation device direct connection is between automobile power source and car light, and is easy for installation, by the detection to signal, do not need to disconnect the line of master cock during installation, and have ultra low dropout, even also do not influence the manual control of light after the device damage, can effectively improve the safety and the stability of vehicle;

4, has powerful defencive function; protective circuit energy auto alarm when wiring error occurring; can detect car category automatically and select cooresponding protected mode by protective circuit; also having increased back car crosses nearly warning and forbids more road warning; in time remind chaufeur situation on every side; be convenient to chaufeur and make right judgement and operation, can prevent the generation of burst accident, guarantee driving safety.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Multi-purpose vehicle(MPV) light automatic guidance installation device of the present utility model is connected between automobile power source and the automobile lamp, and is in parallel with the car bulb hand control switch.

As shown in Figure 1; a kind of multi-purpose vehicle(MPV) light automatic guidance installation device; in the installation device housing, be provided with microprocessor 1 and power circuit 5, be connected with light detector 2, manual identification circuit 3, output circuit 4, protective circuit 6 and vehicle preset device 7 on the described microprocessor 1 respectively.Referring to Fig. 3, microprocessor 1 is based on the programmable chip of prior art, can carry out data sink, analysis, processing and transmission output etc. according to the program that input is provided with; Referring to Fig. 5, the external lug of power circuit 5 is connected with automobile power source, provides stable voltage to this device, to ensure the normal use of installation device; The mouth of output circuit 4 links to each other with automobile lamp, and the control signal of microprocessor 1 is passed to automobile lamp, realizes the open mode of various light; Vehicle preset device 7 built-in various vehicle mode datas, microprocessor 1 accesses the vehicle pattern during device start from vehicle preset device 7, and selects to be fit to the pattern of this car; Referring to Fig. 4, manual identification circuit 3 can be discerned hand signal at any time, and hand signal is passed to microprocessor 1, realizes manually and the automatically controlled switching; Light detector 2 adopts the light sensation sensor, gathers external ambient light degree of illuminating automatically and signal is passed to microprocessor 1; Protective circuit 6 has the wiring error report, back car is crossed nearly warning and forbidden more road warning function, can protect the normal operation of installation device.

Described microprocessor 1 comprises power module, protection module, vehicle processing module, manual identification module, illumination analysis module, automatic processing module and output module.By the program of establishment each module is carried out the functionalization setting in the microprocessor 1, give each module different functions respectively.

When automatic guidance installation device of the present utility model is installed, do not need broken string, can directly be connected with car light, and have ultra low dropout with power supply, because and be parallel way between the hand control switch, even do not influence the manually operation of control of car light after installation device is damaged yet.

Referring to Fig. 2, during automobile starting, connect automobile power source, power circuit 5 is the power supply of this device, the automatic guidance installation device brings into operation; Light detector 2 environment to external world carries out light collection identification and with the signal conversion, and the data of illumination brightness are sent to microprocessor 1; Microprocessor 1 enters mode of operation simultaneously, the power module of microprocessor 1 at first detects the power supply of device, and provide stable voltage for microprocessor 1, if power supply occurs unusual, send warning immediately, if normal condition, then microprocessor 1 accesses the vehicle pattern that is fit to this car automatically in vehicle preset device 7.In vehicle preset device 7, preset the data of various vehicle patterns, three types on lampet, low beam, lamp far away arranged usually, and three kinds of lamps just have respectively and open, just do not close according to automobile; Negative opening, not negative closing; Just do not open, just close; Not negative opening, negative closing; Just open negative closing; Negative opening just closed six kinds of patterns, adds the positive and negative master mode of independently overtaking other vehicles again, and output of two lamp systems and four lamp system output modes can provide the light of 432 kinds of different automobile types to open pattern to greatest extent, can satisfy the various demands of vehicle lamp light mode in the market.Then the protection module in the microprocessor 1 is at the vehicle pattern of calling; select corresponding protected mode; and send signal the internal circuit of whole installation device is detected; if occur opening circuit, short circuit, situations such as wiring error or partial circuit damage are arranged; protection module changes guard mode automatically over to, and gives a warning by protective circuit 6, if after protection module is in guard mode; the light that the automatic guidance installation device can not Control of Automobile then can only be by manually controlling.Simultaneously protection module is also by protective circuit 6, during from automobile starting, the too near vehicle of motor vehicle environment distance etc. monitored in real time, sends when crossing nearly vehicle and forbidding more the road closely to warn and forbid more road warning.When protection module detects after device circuit is normal condition, start and specify the vehicle processing module, the vehicle processing module is in conjunction with the data of illumination analysis module, selected automatically good a kind of pattern that current vehicle uses that is fit to from the vehicle pattern that microprocessor 1 is called in.Whether have hand signal to detect by the manual identification module to current then, if hand signal is arranged, then hand signal is preferential, carry out by the control signal of manually input; If no hand signal, then microprocessor 1 is passed to automatic processing module with data-signal; When if light is in automatic guidance, at any time import manual control signal, manual identification circuit 3 all changes light control over to manual state of a control, realize that manually control is preferential, manually with the function of controlling simultaneously automatically, need not conversion, strengthened the operability of control system, more convenient chaufeur makes a choice according to actual conditions.When the manual identification module detects no manual control signal, microprocessor 1 is with the extremely automatic processing module of data transfer, lamp light mode is carried out automation to be handled, and automatic control signal is sent to output circuit 4 by output module, output circuit 4 links to each other with automobile lamp, finally realizes the automatic guidance of car bulb.
