Existing automotive lamp needs driver to adjust far/dipped headlight pattern manually, will not automatically adjust long-and-short distant light pattern according to always car situation, due to driver in meeting due to neural high-pressure, often forget regulation, add the security risk of driving.
The content of the invention
The present invention can voluntarily adjust the automobile lighting lamp system of long-and-short distant light there is provided a kind of for problem above according to road conditions automatic switchover long-and-short distant light pattern.
The technical scheme is that：Including main control module, illumination lamp module, distance sensor module and communication module, the illumination lamp module, distance sensor module and communication module are connected with the main control module respectively；
The distance sensor module is connected with the communication module；
The illumination lamp module is provided with controlling switch, and the controlling switch is connected with the main control module.
The VIN ports of the communication module are connected with the VIN ports of the main control module；
+ 5V the ports of the communication module are connected with dc source；
The WEAK1 ports of the communication module and the pin 18 of main control module are connected；
The WEAK2 ports of the communication module and the pin 19 of main control module are connected.
The illumination lamp module includes illuminating lamp drive module and Halogen lamp LED group；
Illuminating lamp drive module and Halogen lamp LED the group connection；
The input of the Halogen lamp LED group accesses the Vout+ ports of the illuminating lamp drive module；
The output end of the Halogen lamp LED group accesses the Vout- ports of the illuminating lamp drive module.
The end of incoming cables of the distance sensor module is connected with dc source, and the leading-out terminal ground connection of the distance sensor module, the signal end of the distance sensor module is connected with the pin 27 of the main control module.
The VIN ports of the illuminating lamp drive module are connected with the VIN ports of the communication module.
Present invention preferably employs KEA 128MCU as main control module, KEA128MCU is integrated with overcurrent protection and overvoltage protection in itself, and performance is stable, and Acclimation temperature scope is wide needed for work.The distance values that the present invention is detected using the distance values prestored in main control module with distance sensor module are mutually compared, when sensor assembly detect to object distance values be less than main control module in prestore distance values when then master control module controls controlling switch force switch long-and-short distant light pattern, long-and-short distant light can automatically switch, and ensure traffic safety.Communication module is also associated with main control module, the state of controlling switch can be sent into in-car to control so that it is state that driver and crew, which can intuitively understand headlamp,.Main control module is integrated with overvoltage protection and overcurrent protection, avoids burning main control module when battery voltage for vehicle is unstable, adds the stability of a system and practicality.

Embodiment
The present invention as shown in figures 1 to 6, including main control module, illumination lamp module, distance sensor module and communication module, the illumination lamp module, distance sensor module and communication module are connected with the main control module respectively.The distance sensor module is connected the illumination lamp module with the communication module provided with controlling switch, and the controlling switch is connected with the main control module.The main control module is preferred to use KEA 128MCU chips; KEA 128MCU integrated chips have current foldback circuit and overvoltage crowbar; with good overcurrent protection and overvoltage protective property; main control module working stability can be protected under power supply on vehicle voltage x current unsure state, it is to avoid main control module is breakdown because of over-voltage and over-current to be burnt.It ensure that the stability of whole system.
Distance sensor module is placed in Chinese herbaceous peony end, distance of the uninterrupted measurement to always car and this car, and by the incoming main control module being connected with distance sensor module of range information, the range information that main control module receives after the incoming range information of distance sensor module with being prestored inside main control module is mutually compared, then force to control the controlling switch by high beam pattern switching into dipped headlight pattern when the range information and the illumination lamp module for being reached or fallen below prestoring inside main control module are in high beam pattern, so as to avoid stimulation of the high beam to opposed vehicle driver as far as possible, the accident for reducing moment blinding occurs, it ensure that the traffic safety of subject vehicle, so as to reduce night traffic accident odds.
The VIN ports of the communication module are connected with the VIN ports of the main control module；+ 5V the ports of the communication module are connected with dc source；The WEAK1 ports of the communication module and the pin 18 of main control module are connected；The WEAK2 ports of the communication module and the pin 19 of main control module are connected.Communication module can be by the state of controlling switch（The state of far/dipped headlight）On the middle control screen of display in the car, driver and crew are facilitated to check.
The illumination lamp module includes illuminating lamp drive module and Halogen lamp LED group；Illuminating lamp drive module and Halogen lamp LED the group connection；The input of the Halogen lamp LED group accesses the Vout+ ports of the illuminating lamp drive module；The output end of the Halogen lamp LED group accesses the Vout- ports of the illuminating lamp drive module.Illuminating lamp drive module provides power supply for Halogen lamp LED group,
The end of incoming cables of the distance sensor module is connected with dc source, and the leading-out terminal ground connection of the distance sensor module, the signal end of the distance sensor module is connected with the pin 27 of the main control module.Information is transmitted to main control module by pin 27.
