The specific embodiment
Below, according to accompanying drawing an embodiment of the present invention is described.
Fig. 1 is the cutaway view that schematically shows the state on vehicle that the night viewing device for vehicle of this embodiment is carried; Fig. 2 is a front elevation of observing the headlight arrangement 10 of vehicle from vehicle front side; Fig. 3 is the cutaway view that schematically shows the detailed structure of headlight arrangement 10, and Fig. 4 is the block scheme of the action control of explanation night-vision devices.In addition, Fig. 2 representes to be configured in the headlight arrangement 10 of vehicle left side, also disposes same headlight arrangement 10 on the vehicle right side.
Like Fig. 1～shown in Figure 4, the night viewing device for vehicle of this embodiment is by headlight arrangement 10, night vision camera machine 20, constitute as the HUD 30 of read out instrument and as the electronic control package (ECU) 40 of control mechanism.
Headlight arrangement 10 carries on the vehicle front part, is to comprise respectively as going giving another the right of way with the dipped beam of guide lamp 4 lamp types with bulb 12 with bulb 11 and conduct with the distance light of guide lamp.Distance light is the bulbs to vehicle front side distant place irradiating illumination light with bulb 11, and dipped beam is to the vehicle front side bulb of irradiating illumination light nearby with bulb 12.
By the way, in the rules of Japan, stipulate, when subtend car and preceding driving are arranged, must light distance light and go with bulb 11, dizzy puzzled with the chaufeur that prevents subtend car and preceding driving.In addition, dipped beam is set luminous intensity distribution and the illumination that can confirm the front obstacle more than the about 40m in the place ahead for bulb 12, and distance light is set the luminous intensity distribution and the illumination of the front obstacle that can confirm that the about 100m in the place ahead is above for bulb 11.Again, in this embodiment, dipped beam must bright lamp with bulb 12 when being designed to distance light with bulb 11 bright lamps.
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 this 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 enumerate out 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 distance light with the 1st position of bulb 11 with leave 2nd position of distance light with bulb 11.To specify 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 through front windshield 1, is the image through 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 this embodiment is made up 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 through 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 this embodiment is to form according to known NTSC mode.
The display light of this display image is injected front windshield 1, through 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.Through with not shown matrix driving drives liquid crystal board 31, just will use the image of the captured vehicle front of above-mentioned night vision camera machine 20 to penetrate as display light.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 that expression headlight arrangement 10 carries aspect the front and back up and down of the vehicle under the state on the vehicle.
Headlight arrangement 10 constitutes like this,, in shell, has two bulb 11,12 and light filters 13 that is, and this shell is with the catadioptre 14 that is positioned at two bulbs, 11,12 back sides and covers 15 and combine and form.The catadioptre 14 of this embodiment is with made, has the light that penetrates from bulb 11,12 to the vehicle front side function of reflecting.In addition, the lid 15 usefulness glass of this embodiment are made, and have the function as lens.
Light filter 13 is configured in the vehicle front side of high beam headlight bulb 11 in shell 14,15, form the tubular that extends to the vehicle fore-and-aft direction.The light filter 13 of this embodiment forms the drum of both ends open.
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.
Elastomeric element 16c such as spring on link mechanism, are equipped with at this.When light filter 13 moved to the 1st position, elastomeric element 16c produced elastic deformation.Stop when screw actuator 17 energisings, then the resilient force because of elastomeric element 16c makes the link mechanism action.Therefore, light filter 13 moves to vehicle front and moves to the 2nd position of leaving 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 this 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 on screw actuator 17, flows moves light filter 13, must have the attractive force of the elastic force that overcomes elastomeric element 16c etc., 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 explained.
At the 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, and under the situation of after not satisfying, stating of forbidding starting conditions, 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 of the image of taking with the NTSC mode.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, through utilizing the visible light of sending from dimmer lamp bulb 12, throw light on to vehicle front side nearby 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 covered visible light from high beam headlight bulb 11 by light filter 13, 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 under the state that does not throw light on from the visible light of two bulbs 11,12, can forbid using the night running of night-vision devices, can positively guarantee safe operation.In addition, as long as high beam headlight bulb 11 is not turned off the light, light filter 13 just can not move to the 1st position, so can avoid covering the 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 to guarantee safe operation.
In addition; In this 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; Lamp bright signal S 3 from distance light switch 52 imports under the situation of ECU 40; 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 break off 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 through the time, also can prevent to export power on signal S5 at short notice intermittently and the lost of life of screw actuator 17.
When light filter 13 is positioned at the 1st position, high beam headlight bulb 11 bright lamps, night-vision devices fire switch 51 has been carried out under the situation of opening operation, light filter 13 is moved after high beam headlight bulb 11 is turned off the light to the 2nd position.
Specifically; From the connection signal of the 1st position detecting switch 18 input ECU 40 and also from ECU 40 when the high beam headlight bulb 11 output lamp bright signals; Import under the situation of ECU 40 at the cut-off signal S2 from night-vision devices fire switch 51, ECU 40 turns off the light high beam headlight bulb 11, then; Behind specified time (for example 2.5 seconds), stop to screw actuator 17 energisings.
Therefore; Night-vision devices fire switch 51 is carried out opening operation and when making night-vision devices stop to move; Before penetrating residual light in high beam headlight bulb 11 light-offs; Can avoid light filter 13 to depart from the 1st position, shoot out visible light on the contrary, guarantee to move fully so can positively utilize night viewing device for vehicle from high beam headlight bulb 11 with the intention of chaufeur.
In addition, in this embodiment, even more than the power on signal S5 output specified time (for example 500ms) of screw actuator 17 outputs, when the connection signal S1 from the 1st position detecting switch 18 does not import ECU 40, the output of power on signal S5 is stopped.Therefore, can prevent because of light filter 13 switch on when unusual the screw actuator 17 that causes abnormal heating or smolder.
In screw actuator 17 energising, light filter 13 moves to the such action in the 1st position once again and carries out stipulated number (for example 4 times) repeatedly when above after the 1st position is removed, the output of power on signal S5 is stopped.Therefore, even the electromagnetic force that screw actuator 17 deteriorations, energising form dies down, can prevent that also light filter 13 is in the 1st position and depart from the bad phenomenon that moves back and forth times without number between the position of this position.
