Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Embodiment one:
As shown in Figure 1, this air conditioning for automobiles inner-outer circulation shifter comprise controller 1, for send the fan initiating signal of air conditioning for automobiles fan switch 2, for detect the speed of a motor vehicle wheel speed sensors 3, for control air conditioning for automobiles inner-outer circulation switch inner-outer circulation switch motor 8 and be arranged in vehicle front bumper for detecting the radar sensor of vehicle and leading vehicle distance.
Number as preferred radar sensor is two, be respectively radar sensor 1 and radar sensor 25, the altitude range that radar sensor 1 and radar sensor 25 are arranged is distance ground 30 ~ 50cm, and the height arranged as preferred radar sensor 1 and radar sensor 25 is distance ground 40cm.The detection range of radar sensor 1 and radar sensor 25 is 3 ~ 5m, and as preferably, the detection range of radar sensor 1 and radar sensor 25 is 3m.
The input end of fan switch 2, wheel speed sensors 3, radar sensor 1 and radar sensor 25 difference connection control device 1, the mouth of inner-outer circulation switch motor 8 connection control device 1.This air conditioning for automobiles inner-outer circulation shifter is also included in and sends the automatic mode switch 9 that air conditioning for automobiles carries out inner-outer circulation automatic switching signal.The mouth of controller 1 is also connected with the read-out 10 for showing air-conditioning automatic switchover state.
As the air-conditioner controller that preferred controller 1 can be air conditioning for automobiles itself.Controller 1 is provided with speed of a motor vehicle threshold value and spacing threshold value one, and the scope of speed of a motor vehicle threshold value is 5 ~ 10km/h, is set to 8km/h as preferred speed of a motor vehicle threshold value, and the scope of spacing threshold value one is 1.5 ~ 3m, is 2m as preferred spacing threshold value one.Presetting comparative figure in controller 1 is routine techniques.
Below the working process of this air conditioning for automobiles inner-outer circulation shifter:
Blower fan belongs to the component part of air conditioning for automobiles, people open the blower fan of air conditioning for automobiles by switch fan switch 2, show that air conditioning for automobiles is started working, now fan switch 2 has electric signal to export, carry out automatic inner-outer circulation switch mode after showing that when people press automatic mode switch 9 air conditioning for automobiles is opened, now automatic mode switch 9 has electric signal to export.Controller 1 carries out triggering and enters work when receiving electric signal that fan switch 2 sends and the electric signal that automatic mode switch 9 sends.
Wheel speed sensors 3 detects the vehicle speed signal of vehicle and signal is sent to controller 1, and radar sensor 1 and radar sensor 25 detect the spacing of vehicle and front vehicles and this spacing signal is sent to controller 1.
The vehicle speed signal that wheel speed sensors 3 sends after triggering by controller 1 and speed of a motor vehicle threshold value compare; The vehicle send radar sensor 1 and radar sensor 25 and the spacing signal of front truck and spacing threshold value one compare.It is routine techniques means that the signal sent sensor compares the function itself had for controller 1.When having one to be less than spacing threshold value for the moment in radar sensor 1 and the vehicle of radar sensor 25 transmission and the spacing signal of front truck, the spacing of vehicle and front truck is less than spacing threshold value one; When being all greater than spacing threshold value for the moment in radar sensor 1 and the vehicle of radar sensor 25 transmission and the spacing signal of front truck, the spacing of vehicle and front truck is greater than spacing threshold value one.
Under the spacing being less than 8km/h and vehicle and front truck in the speed of a motor vehicle after controller 1 triggering work is less than the condition of 2m, controller 1 exports electric signal to inner-outer circulation switch motor 8, and air conditioning for automobiles is switched to Inner eycle pattern by inner-outer circulation switch motor 8; Under the spacing being greater than 8km/h and vehicle and front truck in the speed of a motor vehicle is greater than the condition of 2m, controller 1 exports electric signal to inner-outer circulation switch motor 8, and air conditioning for automobiles is switched to outer circulation pattern by inner-outer circulation switch motor 8.Controller 1 carries out judging that rear output signal is routine techniques means according to the signal that sensor sends, and said process is prior art.
Controller 1 exports electric signal to exporting electric signal while inner-outer circulation switch motor 8 to read-out 10, control the handover information of read-out 10 display automobile air-conditioning inner-outer circulation, handover information comprises the recurrent state residing for air conditioning for automobiles, the mode of operation etc. residing for air conditioning for automobiles.
The vehicle condition of relatively coming accurately judge Current vehicle residing for of electric signal of this air conditioning for automobiles inner-outer circulation shifter by sending wheel speed sensors 3, radar sensor 1 and radar sensor 25, and according to the vehicle condition of Current vehicle, the inner-outer circulation of air conditioning for automobiles is switched.
It is prior art that the spacing signal that the vehicle speed signal that wheel speed sensors 3 sends by controller 1 and the speed of a motor vehicle threshold value be provided with compare and sent by radar sensor and spacing threshold value compare process, and judges rear output control signal also as ordinary skill in the art means to the sensor transmission signal.In this air conditioning for automobiles inner-outer circulation shifter, the flow direction of the annexation of each components and parts, the setting position of radar sensor and electric current is protection main points, does not relate to the improvement to program.
