The specific embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.
As shown in Figure 1, this intelligence prevention headlight does not close device and comprises battery management system 4, reminding unit 11 and be used for the car light control unit 2 that control automobile front lamp 9 is carried out open and close, car light control unit 2 connecting headlamps 9, and this reminding unit 11 is buzzer phone or loudspeaker.This device also comprises for the light sensation sensor 6 that gathers light intensity, be used for providing driving engine to turn stop signal engine management system 8, be used for gathering having on the driver's seat and pilotlessly be arranged at the pressure sensor 5 of driver seat cushion below and be used for judging according to the collection signal that receives and process and microcontroller 7 that the output control signal is sent out, microcontroller 7 is connected with car light control unit 2, and microcontroller 7 also is connected with delay unit 1.Microcontroller 7 connects respectively light sensation sensor 6, battery management system 4, engine management system 8, pressure sensor 5, car light control unit 2 and delay unit 1 by On-board LAN CAN bus, and microcontroller 7 also is connected with reminding unit 11 by rigid line.
Also connect electrical control unit 3 in the car by the CAN bus as priority scheme microcontroller 7.The switch of the interior electrical equipment 10 of electrical control unit 3 monitoring cars also controls cutting out of the interior electrical equipment 10 of car.Be used at the additional function of accumulator electric-quantity during less than setting value, electrical equipment 10 cuts out in the indirectly control car.
Simultaneously existing several nouns are further explained: battery management system 4 is called for short BMS, can improve the degree of utilization of battery, prevents that battery from occurring overcharging and overdischarge, prolongs the service life of battery, the state of monitoring battery.Battery management system itself has the function of monitoring battery dump energy, so the storage battery dump energy information that this device receives is carried out the provider by battery management system 4.Engine management system 8 is called for short EMS, and EMS adopts various sensors, and the situations such as driving engine air amount amount, cooling water temperature, engine speed and acceleration and deceleration are converted to electric signal, sends into controller.Controller compares these information and storing information, exports control signal after the accurate Calculation.EMS not only can accurately control fuel supply volume, replacing traditional carburettor, and can control spark advance angle and idling charge air etc., has greatly improved engine performance.Engine management system 8 is monitored the running condition of driving engines simultaneously.The engine stop turn signal that this device receives is provided by engine management system 8.
Below be the principle of work that this intelligence prevention headlight does not close device:
When engine stop rotated, engine management system 8 passed on danger signal of driving engine for microcontroller 7, and namely vehicle is flame-out stops, and the signal that stops operating of driving engine triggers whole prevention headlight and do not close device and start working.Light sensation sensor 6 detects in real time current ambient light intensity and sends to microcontroller 7, and pressure sensor 5 detects and has or not personnel to produce pressure on the operating seats and collection signal sends to microcontroller 7 simultaneously.
No matter how many light intensities that light sensation sensor 6 detects is, as long as microcontroller 7 receives pressure sensor 5 and detect the detection signal that chaufeur sends in car, microcontroller 7 is accepted the Der StandlichtScheinwerfer und Parkleuchtenschalter situation of car light control unit 2 feedbacks, then transmit control signal to reminding unit 11 for opening at monitoring Der StandlichtScheinwerfer und Parkleuchtenschalter state, buzzer phone sends tweeting sound chaufeur is carried out alarm.
The light intensity that detects at light sensation sensor 6 is greater than the light intensity value of setting, be that weather condition may be daytime, and the pressure signal under the operator's seat cushion detects chaufeur not in car the time, microcontroller 7 send close headlight 9 control signals by delay unit 1 to car light control unit 2,2 time-delay a period of times of car light control unit receive control commands control and carry out and turn-off headlights 9.
The light intensity that detects at light sensation sensor 6 is less than the light intensity value of setting, microcontroller 7 receives the storage battery state of charge of battery management system 4 monitorings, and when driver's seat pressure sensor 5 detects the pressure signal of chaufeurs in car, the battery charge will state that microcontroller 7 receives battery management system 4 monitorings is that enough dump energies are arranged, and then microcontroller 7 control reminding units 11 carry out the buzzing reminding alarm; When the electric charge of storage battery is less than vehicle and again starts the preset lower limit of minimum quantity of electric charge of needs, microcontroller 7 is directly controlled the Lighting Controller outage, and the interior electrical control unit 3 of control car is given electrical equipment 10 outages in the car of opening in the time of necessary, and whether electrical equipment 10 is being opened by electrical control unit 3 and fed back to microcontroller 7 in the car.After closing headlight and Che Nei electrical equipment by delay unit 1 after time-delay a period of time whole intelligence prevention headlight do not close the device autoshutdown.
Microcontroller 7 receive light intensity that light sensation sensors 6 detect less than the lower limit of light setting value be intensity of light a little less than, simultaneously microcontroller 7 receives pressure sensors 5 and detects chaufeur not in car the time, when the storage battery state of charge of microcontroller 7 reception battery management systems 4 monitorings was no less than setting value, microcontroller 7 sending controling instructions were closed to car light control unit 2 control headlights 9.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as electrical equipment 10, reminding unit 11 in delay unit 1, car light control unit 2, electrical control unit 3, battery management system 4, pressure sensor 5, light sensation sensor 6, microcontroller 7, engine management system 8, headlight 9, the car, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
