Abstract
The utility model discloses an automobile automatic steering illuminating device based on a single-chip microcomputer, which comprises a steering wheel turning sensor, the single-chip microcomputer, a stepping motor, a head lamp, a stepping motor shaft, a head lamp gear, a rack and a head lamp arm. The head lamp can be automatically angularly adjusted during steering, the problem that a fixed head lamp causes 'illumination dead angle' during steering is solved, and accordingly night driving safety is improved. Further, the automobile automatic steering illuminating device has the advantages of simplicity, practicality, high reliability and the like.
Description
Technical field
The utility model belongs to automobile intelligent control field, more specifically, relates to a kind of SCM Based automobile automatic steering illumination equipment.
Background technology
At present the head lamp on the automobile all is fixed together with vehicle body mostly, and night, automobile was when turning like this, and the road surface light of curve inner side is basically according to less than, Here it is usually said " illumination dead angle ".Because the existence at " illumination dead angle ", chaufeur is difficult to see clearly the road surface situation when turning night, particularly bigger in the bend angle, under the comparatively faster situation of the speed of a motor vehicle, and when on mountain road, going, occurrence of traffic accident very easily.So develop a kind of can be when the chaufeur steering wheel rotation, the illumination equipment that rotates automatically just seems particularly important.
What present technical method adopted mostly is mechanical type automobile automatic steering means of illumination; Though mechanical type automobile automatic steering illumination equipment is better than traditional fixed type means of illumination to a great extent, but still has a lot of weak points, for example complex structure; Not easy to operate, and very flexible etc.
Summary of the invention
Defective or deficiency to above-mentioned prior art existence; The purpose of the utility model is; A kind of SCM Based automobile automatic steering illumination equipment is provided; This device can automatically be regulated the angle of head lamp according to the corner of bearing circle, for chaufeur provides best information of road surface, improves the safety of night travel.
To achieve these goals, the utility model is taked following technical solution:
A kind of SCM Based automobile automatic steering illumination equipment comprises bearing circle, head lamp, it is characterized in that, also comprises:
Be installed in the steering wheel angle sensor in the bearing circle rotating shaft, be used to gather the real-time corner and the direction information of bearing circle;
One micro controller system, the corner that is used for calculating head lamp according to the corner of bearing circle and direction information with turn to, and the control step motor rotates;
One stepping motor by Single-chip Controlling work, drives head lamp through rack and pinion drive mechanism and correspondingly rotates.
Steering wheel angle sensor is connected with the micro controller system input end, and stepping motor is connected with the micro controller system mouth, and gear is equipped with in the end of head lamp arm, is provided with the tooth bar that cooperates with the end gear of head lamp arm in the end of step motor shaft.
Other characteristics of the utility model are:
Described micro controller system is selected 89C51 type micro controller system for use.
Said steering wheel angle sensor adopts the LWS3 series steering wheel angle sensor of anisotropic magnetoresistive sensor.
The SCM Based automobile automatic steering illumination equipment of the utility model; Can be when turning to the angle of automatically regulating head lamp; Solved the fixed type head lamp owing to turn to " illumination dead angle " problem of bringing; Improve the safety of night travel, and had simple and practical, reliability advantages of higher.
Description of drawings
Fig. 1 is that the parts of the utility model are formed scheme drawing.
Fig. 2 is the utility model physical construction scheme drawing.
Label among the figure representes respectively, 1, steering wheel angle sensor; 2, micro controller system; 3, stepping motor; 4, head lamp; 5, step motor shaft; 6, head lamp gear; 7, tooth bar; 8, head lamp arm.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to explain.
The specific embodiment
With reference to Fig. 1,2, present embodiment provides a kind of structure of SCM Based automobile automatic steering illumination equipment, comprises steering wheel angle sensor 1, micro controller system 2, stepping motor 3, head lamp 4, step motor shaft 5, head lamp gear 6, tooth bar 7 and head lamp arm 8.
Steering wheel angle sensor 1 is installed in the bearing circle rotating shaft, is used for gathering in real time steering wheel angle and direction information;
Stepping motor 3 by micro controller system 2 Control work, drives head lamp 4 through rack and pinion drive mechanism and correspondingly rotates.
Steering wheel angle sensor 1 is connected with micro controller system 2 input ends, and stepping motor 3 is connected with micro controller system 2 mouths, and the end fitting of head lamp arm 8 has gear 6, is provided with the tooth bar 7 that cooperates with the end gear 6 of head lamp arm in axle 5 the end of stepping motor 3.
In the present embodiment, micro controller system 2 can be selected 89C51 type micro controller system for use, and steering wheel angle sensor 1 adopts the LWS3 series steering wheel angle sensor of anisotropic magnetoresistive sensor.
The SCM Based automobile automatic steering illumination equipment of the utility model, its working process is following:
The steering wheel angle sensor 1 that is installed in the vehicle steering rotating shaft rotates with bearing circle; The direction of rotating is consistent with the direction of bearing circle; The angle of rotating is through calculate as follows: if the hard-over of head lamp 4 is 20 degree, and the corner of general vehicle steering is two circles, i.e. 720 degree; Multiply by 20 so the angle that head lamp 4 rotates just equals the angle of bearing circle rotation again divided by 720, i.e. the angle of bearing circle rotation is divided by 36.
After device started, steering wheel angle sensor 1 was gathered the corner value and the rotation direction information of vehicle steering in real time, and passes to micro controller system 2.The instantaneous value and the direction of the steering wheel angle that micro controller system 2 receive direction dish sensors 1 transmit, and calculate head lamp 4 cooresponding corner value and direction informations according to predefined method.Micro controller system 2 is according to the corner value and the direction information that calculate; 3 displacements of control step motor; Tooth bar 7 interlocks that are located at step motor shaft 5 ends are arranged on gear 5 rotations of head lamp arm 8 ends; Thereby drive head lamp 4 and rotate corresponding angle, and rotation direction is consistent with bearing circle, thereby realize the technical requirements that head lamp 4 rotates with bearing circle in the same way.
