Abstract
A kind of reversing auxiliary lighting apparatus, for improving reversing safety and traveling comfort of driving, its technical scheme is, it comprises shift sensor, light intensity sensor, AD converter, micro controller system, illuminating lamp and illuminating lamp driving circuit, the astern signal mouth of described shift sensor connects the P1.0 port of micro controller system, the mouth of described light intensity sensor connects the P1.1 port of micro controller system through AD converter, the input end of described illuminating lamp driving circuit connects the P2.0 port of micro controller system, exports termination illuminating lamp.The utility model utilizes light intensity sensor to gather ambient brightness information, when automobile be linked into reverse gear and the threshold value of ambient brightness lower than setting time, micro controller system exports control signal, by two illumination lamp ignitions.The utility model can ensure that in reversing process, automobile rear has enough brightness and do not need chaufeur to carry out any operation bidirectional, substantially increases the driver comfort of reversing safety and vehicle.
Description
Technical field
The utility model relate to a kind of can the reversing auxiliary lighting apparatus that automatically starts and close of bright-dark degree environmentally, belong to automobile technical field.
Background technology
Along with the development of science and technology, people are to vehicle safety and take advantage of the requirement of driving traveling comfort more and more higher.At present, although all automobiles are all configured with backing-up lamp, most of backing-up lamp can not provide enough brightness, and when ambient light of moveing backward is darker, chaufeur is difficult to see clearly situation after car, cannot ensure safety of moveing backward.Although some automobiles have been configured with reversing auxiliary lighting apparatus, but existing reversing auxiliary lighting apparatus all bright-dark degree environmentally can not start and cuts out automatically, and need by chaufeur Non-follow control, its degree of automation is low, operate more loaded down with trivial details, reduce the driver comfort of vehicle.
Utility model content
The purpose of this utility model is the drawback for prior art, provide a kind of can the reversing auxiliary lighting apparatus that automatically starts and close of bright-dark degree environmentally, to improve reversing safety and traveling comfort of driving.
Problem described in the utility model realizes with following technical proposals:
A kind of reversing auxiliary lighting apparatus, formation comprises shift sensor, light intensity sensor, AD converter, micro controller system, illuminating lamp and illuminating lamp driving circuit, the astern signal mouth of described shift sensor connects the P1.0 port of micro controller system, the mouth of described light intensity sensor connects the P1.1 port of micro controller system through AD converter, the input end of described illuminating lamp driving circuit connects the P2.0 port of micro controller system, exports termination illuminating lamp.
Above-mentioned reversing auxiliary lighting apparatus, described illuminating lamp driving circuit comprises aerotron and relay, connect power line voltage after the control coil of described aerotron and relay is connected in series, its base stage connects the P2.0 port of micro controller system through repeating resistance, and the open contact of described relay controls illuminating lamp.
Above-mentioned reversing auxiliary lighting apparatus, described illuminating lamp arranges two, and they are connected in parallel and are arranged on the both sides of automobile tail respectively.
Above-mentioned reversing auxiliary lighting apparatus, the control coil of described relay is connected to flywheel diode.
Above-mentioned reversing auxiliary lighting apparatus, described light intensity sensor is arranged on automobile tail.
The utility model utilizes light intensity sensor to gather ambient brightness information, when automobile be linked into reverse gear and the threshold value of ambient brightness lower than setting time, micro controller system exports control signal, by two illumination lamp ignitions.The utility model can ensure that in reversing process, automobile rear has enough brightness and do not need chaufeur to carry out any operation bidirectional, substantially increases the driver comfort of reversing safety and vehicle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is electric functional block diagram of the present utility model.
In figure, each list of reference numerals is: L1, the first illuminating lamp, L2, the second illuminating lamp, T, shift sensor, G, light intensity sensor, Q, aerotron, D, flywheel diode, U1, micro controller system, U2, AD converter, J, relay, R, repeating resistance.
Detailed description of the invention
Referring to Fig. 1, the utility model comprises two illuminating lamps, shift sensor T, light intensity sensor G, aerotron Q, sustained diode, micro controller system U1, AD converter U2, relay J and repeating resistance R.
Install a light intensity sensor G at automobile tail, vehicle tail both sides add an automobile high-brightness lighting lamp respectively.Light intensity sensor detects extraneous light intensity, and by the signal transmission of collection to micro controller system U1, shift sensor detects gear information (whether being in the state of reversing gear) simultaneously, and gear information is passed to micro controller system U1, micro controller system U1 controls illuminating lamp according to the signal of two sensor collections.When light is enough strong or automobile is linked into non-reversing gear, illuminating lamp is closed automatically; When insufficient light and automobile is linked into when reversing gear, illuminating lamp is lighted automatically, for navigating mate provides enough light intensities, prevents safety misadventure.This device can identify extraneous light intensity and gear situation automatically, avoids unnecessary breakdown action.
The analog signal that AD converter U2 is used for light intensity sensor G gathers converts digital signal to, micro controller system U1 is used for carrying out threshold value and compares and simple Logic judgment, therefore also can be replaced with door by a comparator and one, two input ends of comparator connect the output signal of light intensity sensor G and the VREF (Voltage Reference) corresponding with the threshold value of setting respectively, connect the output signal of comparator and shift sensor T respectively with two input ends of door, export termination illuminating lamp driving circuit.Aerotron Q and relay J are for controlling the power supply of two illuminating lamps, and the surge voltage that sustained diode produces for the control coil absorbing relay J, protects the safety of aerotron Q.
