Background technology
Car headlamp is important automobile active safety parts, especially when night travel, can provide illumination functions.Show according to foreign statistic, although the vehicle flowrate at night less than daytime vehicle flowrate 1/5th, nocturnal traffic accident, but surpass always have an accident 1/4th.To the driver, do not having street lamp to have again that on the road of many bends, steering vehicle is very unsafe night, the sight line that shows the driver is limited in the linear extent of headlight beam irradiation, if can not carrying out servo-actuated irradiating angle according to turning to of automobile, regulates head lamp, for emergent people or thing in detour, chaufeur can't in time be predicted, and this very easily causes the generation of traffic accident.
At present to the follow-up mechanism of head lamp, the technology that adopts mainly contains: manual adjustment system, quasistatic illumination distances control system, dynamic lighting distance adjustment system.Manual adjustment system is not subject to extensive concern because of the direction that can not in time change rapidly head lamp.Quasistatic illumination distances control system can be proofreaied and correct headlight change of pitch angle amount according to the variation of load carrying ability.Dynamic lighting distance adjustment system except the variation of considering load carrying ability, has also considered accelerate and slow down on the impact of headlight change of pitch angle.
At present, the technology of carrying out the steering indicating light follow-up adjustment based on the loads change of automobile is mature on the whole, but the follow-up adjustment of head lamp also rarely has research when turning to.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is, a kind of SCM Based vehicle electronics differential gear is provided.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
Follow-up illumination control setup during a kind of motor turning, comprise angular transducer, yaw-rate sensor, speed sensor, A/D converter, micro controller system, left front illuminating lamp light deflector as drive motor and right front illuminating lamp light deflector as drive motor, angular transducer, yaw-rate sensor and speed sensor are connected with the input end of micro controller system by A/D converter respectively, the mouth of micro controller system be connected with left front illuminating lamp light deflector as drive motor and right front illuminating lamp light deflector as drive motor.
The utility model also has following technical characterstic:
Described Central Processing Unit (CPU) adopts single chip computer AT MEGA16.
