The illumination light of two bulbs 11,12 mainly contains the wavelength components in visible light zone, and distance light except the wavelength components that contains the visible light zone, also contains the infrared wave long component with the illumination light of bulb 11 at least.The distance light of present embodiment adopts the bulb 11 that contains the near infrared wavelength components in the infrared ray with bulb 11.As the object lesson of this distance light, can list well-known halide torch with bulb 11.
In addition, headlight arrangement 10 has the visible light of covering and sees through near infrared light filter 13, and this light filter 13 can be changed to move to and cover 1st position and 2nd position of leaving distance light usefulness bulb 11 of distance light with bulb 11.To describe in detail in the back about this moving structure.
Night vision camera machine 20 is near the indoor upper limb that is bearing in front windshield 1 of car, being the equipment of taking vehicle front by front windshield 1, is the image by the infrared ray sensitization that is reflected by the object of vehicle front among the infrared ray that penetrates with bulb 11 from distance light being taken vehicle front.The night vision camera machine 20 of present embodiment is made of not shown telephoto lens, image mechanism, vision signal generating mechanism etc.
Specifically, image mechanism is the charge coupled cell (CCD element) that the image of vehicle front is transformed into electric signal.The vision signal generating mechanism is based on the electric signal that is transformed into by the CCD element, produces the microcomputer of the vision signal of having given vertical synchronizing signal, horizontal synchronizing, burst signal etc.In addition, the vision signal of present embodiment is to form according to known NTSC mode.
HUD 30 is provided on the instrument carrier panel 2 that extends to the car indoor from the lower edge of front windshield 1, it comprises as the TFT type liquid crystal board 31 of display part and back of the body illuminator 32, liquid crystal board 31 as shown in fig. 1, in the peristome 2b of the upper wall 2a of instrument carrier panel 2, be supported horizontally, the light that this liquid crystal board 31 is accepted from back of the body illuminator 32 demonstrates display image on display frame 31a.
The display light of this display image is injected front windshield 1, by this front windshield 1, along dotted line R shown in Figure 1 to the chaufeur M eye reflection that is sitting on the driver's seat, like this, just the place ahead of windshield 1 is imaged as virtual image m in front.
In addition, supporting back of the body illuminator 32 in the rear side of liquid crystal board 31, these back of the body illuminator 32 bright lamps, light is just injected liquid crystal board 31 from this rear side.By with not shown matrix driving circuit drives liquid crystal board 31, just will penetrate as display light with the image of the captured vehicle front of above-mentioned night vision camera machine 20.Like this, chaufeur can be recognized owing to the image of the vehicle front that makes night becomes virtual image m, therefore, can assist night chaufeur the visual field and guarantee safe operation.
ECU 40 is the electronic control packages that carry out the control of whole night-vision devices, carries out the mobile control of light filter 13, the action control of night vision camera machine 20 and the action control of HUD 30 etc.
Below, with Fig. 3 the structure of headlight arrangement 10 is at length described.In addition, the expression among Fig. 3 up and down the arrow of fore-and-aft direction be expression headlight arrangement 10 carry vehicle under the state on the vehicle up and down before and after aspect.
The arm 16a that extends to shell 14,15 foreign sides is combined on the light filter 13, is combined on the arm 16a as pillar (travel mechanism) 16b of metallic parts.Constitute link mechanism by arm 16a and pillar 16b.
In addition, with screw actuator (travel mechanism) 17 of pillar 16b subtend configuration on during circulating current because the effect of the electromagnetic force that is produced on the screw actuator 17, pillar 16b is attracted by screw actuator 17, makes the link mechanism action.Therefore, light filter 13 moves to rear view of vehicle, thereby moves to the 1st position that covers high beam headlight bulb 11.
The 2nd position is represented in the position of the light filter 13 shown in the solid line among Fig. 3, and high beam headlight bulb 11 is positioned at the outside of tubular light filter 13.In addition, the 1st position is represented in the position of the light filter 13 shown in the long and short dash line among Fig. 3, and high beam headlight bulb 11 is positioned at the inside of tubular light filter 13.
In addition, the symbol 18 expression testing agencies among Fig. 3, this testing agency is used to detect light filter 13 and has moved to the 1st position.In the testing agency 18 of present embodiment, adopt the PS (Push Switch) of recovery type certainly of contact, when light filter 13 moves to the 1st position, then the 1st position detecting switch 18 is pushed by pillar 16b and is become on-state, exports connection signal S1 by the 1st position detecting switch 18 to ECU 40.In addition, when light filter 13 moved to the 2nd position, then pillar 16b left the 1st position detecting switch 18.So the 1st position detecting switch 18 becomes off-state from recovery, just stops to export connection signal S1.
At this, when the electric current that flows moves light filter 13, must have the attractive force of the elastic force that overcomes elastomeric element 16c etc., on screw actuator 17 so need electric current greatly.Just can keep with less electric current when on the other hand, making light filter 13 remain on the 1st position.Therefore, to screw actuator 17 energising the time, do not export the occasion of connection signal S1 at the 1st position detecting switch 18, the control of switching on is with the big electric current of circulation, in output the occasion of connection signal S1 arranged, and the control of switching on is with the less electric current that circulates.
In addition, in shell 14,15, dispose the lampshade 19 that covers light filter 13 from vehicle front side, utilize this lampshade 19 to prevent to see light filter 13 and impair the outward appearance of vehicle from outside vehicle.From bulb 11,12 penetrate and be injected into light on the lampshade 19 by lampshade 19 reflections after, on catadioptre 14, reflect, see through shell 15 and penetrate to vehicle front as illumination light.
Below, with Fig. 4 the action control of night-vision devices is illustrated.
At indoor night-vision devices fire switch (start-up function mechanism) 51 and the bright lamp of operation high beam headlight bulb 11 or the distance light switch (distance light operating mechanism) 52 of light-off usefulness that is provided with the starting of operation night-vision devices or stops usefulness of car.Two switches 51,52 are arranged on the position that the hand of chaufeur can get at, and the well-known cylindricality switch of distance light switch 52 usefulness constitutes with the bright lamp of operation dimmer lamp bulb 12, the switch one of light-off usefulness.In addition, signal S2, the S3 from two switches 51,52 imports ECU 40.
Night-vision devices fire switch 51 is carried out making operation, and making operation signal S2 just imports ECU 40, is not satisfying under the situation of forbidding starting conditions described later, and the action of ECU 40 control various devices is so that the night-vision devices starting.Specifically, lamp bright signal S4 to 11,12 outputs of two bulbs, is made two bulbs, 11,12 bright lamps.And, power on signal S5 to screw actuator 17 outputs, is made circulating current on screw actuator 17, thereby makes light filter 13 move to the 1st position.In addition, make 20 startings of night vision camera machine.Make HUD 30 startings.
When making the night-vision devices starting like this, by 20 pairs in night vision camera machine among the near infrared ray of high beam headlight bulb 11, photograph by the near infrared ray that object reflected of vehicle front, night vision camera machine 20 is with the vision signal output in the NTSC mode of the image taken.Then, drive liquid crystal board 31, penetrate the display light that sends from display frame 31a by back of the body illuminator 32 according to this vision signal.So the image of captured vehicle front becomes virtual image m and is recognized by chaufeur.
Therefore, by utilizing the visible light of sending from dimmer lamp bulb 12, throw light on nearby to vehicle front side in the limit, and the limit shows the vehicle front image at night, thus the visual field and guarantee safe operation at night that can driver assistance person.And, although make high beam headlight bulb 11 bright lamps, owing to the visible light that is covered by light filter 13 from high beam headlight bulb 11, so can not make the dizzy vehicle front image that shows night of the chaufeur of subtend car and preceding driving puzzledly.
But, be arranged in the 2nd position and satisfy under the situation of following 3 at least one conditions of forbidding starting conditions at light filter 13, even when night-vision devices fire switch 51 carried out making operation, ECU 40 forbids that also light filter 13 moves to the 1st position.That is, be dimmer lamp bulb 12 condition of turning off the light, high beam headlight bulb 11 bright lamps condition, and illuminance transducer do not detect condition into night.
Specifically, do not import under the situation of ECU 40 at the connection signal S1 of the 1st position detecting switch 18, be only limited to the occasion in dimmer lamp bulb 12 bright lamps and high beam headlight bulb 11 light-offs, ECU 40 makes the night-vision devices starting according to the input of the making operation signal S2 of night-vision devices fire switch 51.
According to the above, because lamp as long as dimmer lamp bulb 12 does not work, light filter 13 just can not move to the 1st position, so can forbid using the night running of night-vision devices under the state that does not throw light on from the visible light of two bulbs 11,12, can positively guarantee safe operation.In addition, as long as high beam headlight bulb 11 do not turn off the light, light filter 13 just can not move to the 1st position, so can avoid covering visible light from high beam headlight bulb 11 mutually on the contrary with the intention of chaufeur, can positively utilize night viewing device for vehicle assurance safe operation.
In addition, in the present embodiment, being only limited to satisfying the speed of a motor vehicle is more than the 30km/n and under screw actuator 17 output power on signal S5 and the situation of output from the condition of the connection signal S1 of the 1st position detecting switch 18, allows to high beam headlight bulb 11 output lamp bright signal S4.
In the night-vision devices starting, if distance light switch 52 is carried out making operation, then ECU 40 controls like this, promptly, make high beam headlight bulb 11 keep lighting lamp state and light filter 13 is moved to the 2nd position, like this, even in the night-vision devices starting, also can become and the corresponding illumination condition of the operation of distance light switch 52.In addition, though when distance light switch 52 is the general-duty switch too.
Specifically, from the connection signal S1 of the 1st position detecting switch 18 input ECU 40 and from ECU 40 when the high beam headlight bulb 11 output lamp bright signal S4, import under the situation of ECU 40 at lamp bright signal S3 from distance light switch 52, keep state, and stop to screw actuator 17 output power on signal S5 to high beam headlight bulb 11 output lamp bright signal S4.
In addition, when distance light switch 52 becomes to disconnect from connecting conversion operations, when not satisfying above-mentioned at least one and forbidding starting conditions, to screw actuator 17 output power on signal S5 and light filter 13 is moved to the 1st position.By the way, distance light switch 52 is when passing through the switch of (passing) usefulness, through specified time (for example about 1 second) back output power on signal S5.Therefore, though carry out continuously at short notice by the time, also can prevent to export power on signal S5 at short notice intermittently and the lost of life of screw actuator 17.
