    [0001] [0001] Examples of embodiments of the invention relate to a vehicle display system which displays information on a road surface, etc. [0002] Recently, there are vehicle display systems that inform / warn another entity (such as a pedestrian and / or another vehicle) with vehicle information by illuminating (drawing) a drawing, a text etc. on a road surface. For example, JP 2009-184428 A discloses a vehicle display system that informs / warns another entity that is about to enter an intersection that a vehicle is approaching, displaying a trade mark. However, it is difficult to display a drawing and / or text so that another entity can see the drawing and / or the text without the drawing. and / or the text is distorted. Similarly, if the drawing and / or text displayed are distorted, the problem is that the other entity may not identify the information indicated by the drawing and / or the text. Furthermore, in general, a driver of the vehicle is hindered by the display of the other entity. Therefore, the display of the other entity may affect the driver's comfort. The invention has been made in view of the circumstances above. Examples of exemplary embodiments of the invention provide for a vehicle display system that can provide a display such as another entity to be notified easily notices the display and the display does not give a driver a strange vehicle sensation. According to an exemplary embodiment, a vehicle display system displays information on a road surface. The vehicle display system includes a detector of another entity, an intersection detector, and a display device. The other entity detector detects whether another entity is approaching a vehicle equipped with the vehicle display system or not. The intersection detector detects whether the vehicle is approaching an intersection. When the detector of other entity detects that said other entity is approaching the vehicle or when the intersection detector detects that the vehicle is approaching the intersection, the display device displays a predetermined shape in a predetermined area of the vehicle. a road surface at the front of the vehicle while moving the predetermined shape. [0007] With this configuration, when another entity such as a pedestrian or another vehicle and a vehicle are approaching each other or when the vehicle approaches an intersection, the predetermined shape is displayed dynamically on a road at the front of the vehicle. Dynamic displays attract more visual attention from pedestrians or other vehicles than static displays. As a result, the pedestrian or other vehicle may more easily notice that the vehicle is approaching him or the other vehicle. At the same time, the discomfort of the driver of the vehicle can be reduced during driving because the display is made intermittently. [0008] (2) In the system of point (1), the predetermined shape may be a bar-shaped mark extending in forward and backward directions in the predetermined area. The display device can move the predetermined shape in right and left directions in the predetermined area. With this configuration, the simple form is displayed in order to move back and forth. Therefore, the advantageous effects described above can be achieved without worrying about the deformation in the tracing of the predetermined shape. (3) In the system according to any one of the points (1) to (2), one can stop displaying the predetermined shape at a central portion of a vehicle traveling path. With this configuration, the strange sensation that blinking can give the driver of the vehicle C can be reduced. (4) In the system according to any of the points (1) to (2), an amount of light with which the predetermined shape at a central portion of a vehicle traveling path is illuminated may be less than that of the light with which the predetermined shape (M) at right and left portions of the moving path (CR) is illuminated. With this configuration, the strange sensation that the blink can give the driver of the vehicle C can be reduced. (5) In the point system (1), the predetermined shape may be a bar-shaped mark extending in right and left directions in the predetermined area. The display device can move the predetermined shape forward in the predetermined area. With this configuration, the simple form is displayed in order to move forward. Therefore, the advantageous effects described above can be achieved without worrying about the deformation in the tracing of the predetermined shape. (6) In the system according to any of the points (1) and (5), a displacement speed of the predetermined shape may increase towards a front end of the predetermined area. With this configuration, the predetermined shape is displayed with an increase in travel speed when the predetermined shape is further away from the vehicle. Therefore, the other entity is encouraged to pay attention at an early stage of the vehicle approach. [0012] (7) In the point system (5), a width of the predetermined shape may increase towards a rear end of the predetermined area. With this configuration, information regarding a distance to the vehicle can be transmitted to the other entity. (8) In the system (1), the predetermined shape can be moved from a central portion of the predetermined area to side portions of the predetermined area. With this configuration, the simple form is displayed so as to spread out. Therefore, the advantageous effects described above can be achieved without worrying about the deformation in the tracing of the predetermined shape. [0014] (9) In the system according to any one of the points (1) to (7), a contrast between the predetermined shape and a light distribution pattern formed by vehicle headlights can be established in such a way that that the predetermined shape is displayed as a relatively brighter part than the light distribution pattern. With this configuration, the strange sensation that the driver of the vehicle may have can be further reduced. Likewise, the predetermined shape seems to blink for the other entity. As a result, the other entity can more easily notice the predetermined shape. [0015] Examples of embodiments of the invention provide for the vehicle display system which may provide a display such that another entity to be notified easily notices the display and display 3024686 5 does not give to a driver a strange vehicle sensation.

The road fire light source unit 5 forms a road fire light distribution pattern. The passing light light source unit 6 forms a passing light light distribution pattern. The traffic light light source unit 5 and the low beam light source unit 6 may comprise a reflector type fire unit and / or a projection type fire unit. . The types of fire units provided in the main beam light source unit 5 and the low beam light source unit 6 are not particularly limited. The configuration of the low beam light source unit 6 shown in FIG. 2 is just an example. In this example, the low beam light source unit 6 is a projection type fire unit and comprises a light emitting diode 161, a reflector 162, and a projection lens 163. An arrow B1 in the figure 2 indicates a portion of light emitted by the low beam light source unit 6. The main beam light source unit 5 and the low beam light source unit 6 are fixed on a vertical metal support 4 by a horizontal support 3024686 8 or equivalent. The vertical metal support 4 serves as a support member for the main beam light source unit 5 and the low beam light source unit 6. The horizontal support 160 serves as a mask. The vertical support 4 is fixed on the fire body 2 at three corner portions by pointing screws 14. An optical axis of the vehicle fire 1 is adjustable in the upward, downward, rightward and leftward directions. by turning the pointing screws 14. [0022] An extension element 12 is provided in the fire chamber and in front of the traffic light light source unit 5, the fire light source unit of crossing 6, and a display device 8 of the vehicle display system 7 which will be described later.

The extension member 12 serves as a closure member. [0023] (Vehicle display system) The vehicle display system 7 comprises a control circuit 9 and the display device 8. The control circuit 9 comprises a detection section 25 of another entity 56 and an intersection detection section 57. The other entity detection section 56 detects whether a pedestrian, another vehicle, and / or equivalent (which will be called "other entity") approaches the vehicle C. The intersection detection 57 30 detects whether vehicle C is approaching an intersection. The display device 8 comprises a laser light source unit 10 and a scanning mechanism 11. The laser light source unit 10 and the scanning mechanism 11 operate when the detection section of another entity 3024686 9 56 detects that another entity is approaching the vehicle C or when the intersection detecting section 57 detects that the vehicle C is approaching an intersection. [Display] A description of the display device 8 will first be made. The display device 8 comprises the laser light source unit 10 and the scanning mechanism 11 which operate under the control of the control circuit 9 (to be described later). [0025] (Laser Light Source Unit) Fig. 3 is a side view of the laser light source unit 10. It should be noted that Fig. 3 illustrates the laser light source unit 10 such that an interior of the laser light source 10 appears to be seen through a housing. The laser light source unit 10 is an RGB laser unit. In the laser light source unit 10, a first light source 15 which emits a red laser beam, a second light source 16 which emits a green laser beam, and a third light source 17 which emits a laser beam blue are attached to a support block 18 via respective substrates. The lights emitted by the respective light sources 15, 16, 17 are united in parallel beams by the respective light-combining lenses 20, 21, 22, are caused to strike respective dichroic mirrors 25, 26, 27, and pass through the dichroic mirrors 27, 26, 25 to thereby combine the RGB light. Thus, a combined laser beam B2 constitutes a beam of white light. The laser beam B2 is reflected to a light combining lens 19 provided on the housing of the laser light source unit 10, and emitted to the outside of the laser light source unit 10. light combination 19 is not an essential element. The laser light source unit 10 is fixed on a front surface of the vertical support 4 such that an optical axis of the laser light source unit 10 is oriented downward (see Fig. 2). . The laser light source unit 10 comprises a control device 28 which controls outputs of the respective light sources 15, 16, 17. Thus, illumination intensities of the respective light sources 15, 16, 17 and a illumination intensity of the combined laser beam are monitored. The light source (s) of the laser light source unit 10 are not limited to a configuration in which three RGB light sources such as light sources 15, 16, 17 are provided. Alternatively, the one or more light sources of the laser light source unit 10 may be of any configuration as long as they can generate white light. Examples include (i) a single white light source, (ii) four light sources comprising an additional orange laser diode in addition to R, V, and B light sources, and (iii) a configuration in which light emitted by a blue laser diode passes through a yellow fluorescent material. The light sources 15, 16, 17 may be laser devices other than laser diodes. [0026] (Scanning mechanism) Fig. 4 is a perspective view of the scanning mechanism 11. The scanning mechanism 11 is a galvano-mirror. More specifically, the scanning mechanism comprises a base portion 37, a first rotating body 38, a second rotating body 39, first torsion bars 40, second torsion bars 41, permanent magnets 42, 43 , and a terminal portion 44. [0027] The first rotating body 38 is supported by a pair of first torsion bars 40, 3024686 11 which are provided in a central opening portion of the base portion 37, so that able to turn right and left (in the horizontal direction) relative to the base portion 37. The second rotation body 39 is supported by a pair of second torsion bars 41, which are provided in a portion of central opening of the first rotating body 38, so as to be able to turn upwards and downwards (in the vertical direction) with respect to the first rotating body 38. A reflector 36 is formed on a front surface of the second body of rotation rotat ion 39 by a treatment such as a silver deposit or electroplating. A first coil (not shown) connected to the control circuit 9 is wired to the first rotating body 38. In addition, a second coil (not shown) connected to the control circuit 9 is wired to the second rotating body 39. A pair of permanent magnets 42 are provided on the base portion 37 in positions such that a line passing through the positions are perpendicular to a direction in which the first 20 torsion bars 40 extend. A pair of permanent magnets 43 are provided on the base portion 37 in positions such that a line connecting the positions is perpendicular to a direction in which the second torsion bars 41 extend. The first coil and the second coil are connected to the control circuit 9 via the terminal portion 44. The first coil, the permanent magnets 42, the second coil and the permanent magnets 43 constitute a device. Scanning operation 58 shown in Fig. 5 (to be described later). The scanning actuator 58 changes an orientation of the reflector 36 up, down, right and left depending on the rotation of the first rotating body 38 and the rotation of the second rotating body 38. by individually changing (i) driving current quantities flowing in the first and second coils and (ii) directions in which the drive currents flow. The scanning mechanism 11 is fixed by horizontal holding plates 13, 13 so that the reflector 36 is on the optical axis of the laser light source unit 10 and the light emitted by the source of the light source. The laser light 10 is reflected towards the front of the vehicle light 1. As shown in FIG. 2, the horizontal holding plates 13, 13 are fixed on the vertical support 4. The scanning mechanism 11 is fixed by the holding plates 13, 13 to be in a state where the scanning mechanism 11 tilts from a lower front side of fire to a rear upper side of fire. The scanning mechanism 11 may adopt another scanning optical system such as a polygon mirror, or MEMS mirrors which can individually control angles of multiple tiny mirrors using electrical signals. (Control circuit) Figure 5 is a block diagram for explaining the control circuit 9. The configuration in Figure 5 is a simple example. The control circuit 9 can be implemented by semiconductor elements and electrical circuits in a hardware aspect and can be implemented by computer programs in a software aspect. Those skilled in the art will appreciate that the control circuit 9 may be implemented by any of a variety of hardware and software combinations. The control circuit 9 comprises an electronic fire control unit 51, a read-only memory 52, a random access memory 53, and so on. Various control programs are stored in ROM 52. Electronic fire control unit 51 executes the various control programs stored in read-only memory 52 using RAM 53 to generate different control signals. The control circuit 9, for example, is fixed on the fire body 2. The electronic fire control unit 51 can receive data detected by a camera embedded in the vehicle 60, a sensor embedded in the vehicle 62, and an external system 63, via cable communication, wireless communication and / or various other communications. The camera embedded in the vehicle 60 and the sensor embedded in the vehicle 62 are provided in the fire chamber or in the vehicle C. Examples of the sensor embedded in the vehicle 62 comprise a millimeter-wave radar. Examples of the external system 63 include a smart transport system, an intersection camera, and a surveillance camera. The electronic fire control unit 51 may receive data relating to a current position of the vehicle C from a vehicle navigation system 61 provided in the vehicle C, via a wired communication, a communication system, a vehicle, a vehicle, a vehicle, a vehicle, a vehicle. wireless communication or various other communications. The electronic fire control unit 51, the camera on board the vehicle 60, the on-board sensor 62, and the external system 63 may constitute the vehicle display system 7. Similarly, electronic fire control 51, the on-vehicle camera 60, the on-vehicle sensor 62, and the external system 63 are examples of another-entity detector and / or intersection detector. The electronic fire control unit 51 also comprises a laser light source control unit 54, an operating device control section 55, the other entity detection section 56, and the intersection detecting section 57. [0032] The detecting section of another entity 56 acquires / detects information indicating that another entity is approaching the vehicle C from the devices (the camera embedded in the vehicle 60, the on-board sensor 62, and the external system 63) that detect the presence of the other entity or other entities. The intersection detection section 57 acquires / detects information indicating that the vehicle C is approaching an intersection from the camera on board the vehicle 60 or the vehicle navigation system 15. When the other entity detecting section 56 detects that another entity is approaching the vehicle C or when the intersection detecting section 57 detects that the vehicle C is approaching an intersection, 20 laser light source control unit 54 controls a color, an emission intensity and a start / stop of a laser beam of each of the light sources 15, 16, 17, on the basis of the information acquired by the other entity detection section 56 and the intersection detection section 57. [0035] Moreover, when the detection section of another entity 56 detects that another entity is approaching the vehicle C or when the intersection detection section 57 detects that the vehicle As C approaches an intersection, the actuator control section 55 controls the scan driver 58 (i) based on information acquired by the other entity's detection section. 56 and the intersection detection section 57 and (ii) in coordination with the control 3024686 performed by the laser light source control unit 54, so as to scan a scanning zone SA with the laser beam B2. [0036] (Display by the vehicle display system) Fig. 6 is a diagram showing a light distribution formed by the vehicle light 1. Fig. 7 is a diagram for explaining how the vehicle display system vehicle 7 displays. Fig. 6 shows a virtual vertical screen which is virtually in a position 25 m in front of the vehicle light 1. The vehicle light 1 forms a passing beam light distribution pattern PL thanks to the source unit Beam light 6 and 15 form a road fire light distribution pattern PH through road fire light source unit 5. Shapes of the crossing light and road light distribution models PL , PH are known. A detailed explanation of it is thus omitted. A sign "CR" 20 indicates a lane (road surface) in which the vehicle C must move. The vehicle display system 7 is provided to be able to scan a rectangular scan area SA shown in FIG. 6. It is preferable to provide the scan area SA of the vehicle display system. 7 in order to cover a road stop band and a track adjacent to the CR track and to cover from 10 meters to 50 meters ahead of the C vehicle. It is also preferable to provide the SA 30 sweep area so that upper and lower extremities of the SA scan area on the virtual vertical screen are in the range of -0.5 ° to -4 ° with respect to the HH line and the right and left ends of the SA scan area 3024686 16 on the virtual vertical screen are in a range of -10 ° to 10 ° relative to the VV line. First, when the vehicle display system 7 is turned on, the control circuit 9 5 receives data from the camera embedded in the vehicle 60, the sensor embedded in the vehicle 62, the system 63, and the vehicle navigation system 61, and acquires information such as a position of an intersection 73 by means of the intersection detection section 57. At the same time, the control circuit 9 acquires information such as the presence of a pedestrian 71, the presence of another vehicle 72, a position of the pedestrian 71, and the position of the other vehicle 72, by means of the detection section of other entity 56.
    [0003] The vehicle display system 7 can be automatically started when the vehicle C is started or can be started by means of an operating switch provided in the vehicle C. [0039] Then, when the detection section 20 of another entity 56 detects that another entity is approaching the vehicle C or when the intersection detecting section 57 detects that the vehicle C is approaching an intersection, the control circuit 9 causes the display device 8 to dynamically trace a mark M having a predetermined shape. Criteria (determination criteria) for detecting whether or not another entity is approaching vehicle C and criteria (criteria for determining) whether or not vehicle C is approaching a vehicle intersection can be established on the basis of the knowledge that one skilled in the art has. With regard to the detection made by the detection section of another entity 56, a different criterion for determining whether or not another entity approaches the vehicle C may be provided for the case where the other entity 3024686 17 is a pedestrian and the case where the other entity is another vehicle. In addition, the case where a pedestrian approaching the vehicle C is one that crosses a road and the case where a pedestrian approaching the vehicle C is one who is walking along a road may use the different criterion for the determination. FIG. 7 shows an example of the mark, which is dynamically drawn by the display device 8 when the detection section 10 of another entity 56 detects that another entity is approaching the vehicle C or when the intersection detecting section 57 detects that the vehicle C is approaching an intersection. An symbol Si designates an example of a scan line. When scanning the scanning zone SA, light 15 emitted by the display device 8 is moved along the scanning line S1. The scanning mechanism 11 switches the reflector 36 on the basis of a control signal of the actuator control section 55, and scans the scanning zone SA horizontally at a high speed while moving a position of the light emitted downwards from a minimum distance dl. In coordination with this, the laser light source unit 10 turns on some or all of the first to third light sources (15 to 17) on the basis of a control signal from the source control unit. laser light 43 during a period in which the scanning mechanism 11 scans an area where the mark M is to be drawn, so as to emit the laser beam B2. In addition, the laser light source unit 10 stops all of the first to third light sources (15 to 17) during a period in which the scanning mechanism 11 scans outside the area where the mark M must be drawn. In Fig. 7, the dashed portions of the scan line S 1 indicate parts that are scanned while the first to third light sources 17 are turned off. Likewise, the solid line portions of scan line S1 indicate portions that are scanned while a portion or all of the first to third light sources are illuminated. The vehicle display system 7 travels around the high speed SA scanning area. That is, it takes a short time for the vehicle display system 7 to scan the scan area SA one time. Thus, the vehicle display system 7 can trace the M mark having an arbitrary shape by stacking beam emission points each of which is formed by a lathe (single scan). For example, if it is desired to move the mark M to the right, a second scan following the first scan traces a mark M2 which is moved to the right with respect to a mark M1 formed by the first moved scan of a minimum distance d2. Then, the third scan traces a mark M3 which is moved to the right with respect to the mark M2 formed by the second scan of the minimum distance d2. This process is repeated until a mark Mn in a predetermined position. As a result, the mark M is displayed so that the mark M appears to move to the right in the predetermined area. There is no limitation to scanning with the scanning mechanism 11 in the horizontal direction, and appropriate scanning may be adopted depending on the shape and / or movement of the M mark. [0041] Suitable examples of the mark M, which is dynamically displayed by the vehicle display system 7, will be described below with reference to FIGS. 8A to 10. FIGS. 8A to 10 show the vehicle C and the mark M from above. Reference 71 indicates a pedestrian, reference 72 indicates another vehicle, and reference 73 indicates an intersection. In the following description, front, back, right and left are defined with reference to a state where the mark M is seen from above (the state shown in FIGS. 8-10). (First example) FIG. 8A is an explanatory diagram of a first example of the vehicle display system. Figures 8B and 8C are modifications of the first example.
    [0004] In the first example, as shown in FIG. 8A, a predetermined area D is provided to have a shape that spans a track width of the travel path CR in which the vehicle C rolls and which spreads in shape. fan. A width of the predetermined area D in the right and left directions may be fixed and set in advance based on the knowledge of one skilled in the art. Alternatively, the electronic fire control unit 51 can detect lane markings, road shoulders, and the like from data acquired by the on-board camera 60 and the like, specify a road width, and set the width of the predetermined area D in the right and left directions according to the specified track width. It is preferred that a length of the predetermined area D in the forward and reverse directions be set to cover a range of 10 meters to 15 meters in front of the vehicle C. It is also preferable that the length of the predetermined area D in the forward and reverse directions is set up so that a pedestrian who is further than a distance at which the vehicle control can avoid the collision between the vehicle C and the pedestrian even if, in the worst case the pedestrian had to walk on the road. The vehicle display system 7 detects whether the pedestrian 71 or the other vehicle 72 approaches or not the vehicle C and detects whether the vehicle C approaches the intersection 73. Then, on the basis of (i) information relating to the approach that is detected the earliest, or (ii) information concerning that of pedestrian 71, the other vehicle 72, and intersection 73 which is determined to be in a state where it has the greatest warning need, the vehicle display system 7 displays the mark M in the predetermined area D. The mark M has the bar shape which extends in the forward and backward directions. The predetermined shape D has the fan shape. A sequential scan in scan area SA is repeated to thereby display the mark M in the predetermined fan-shaped area D while periodically moving the mark M in the right and left directions. It is preferred that the M mark be moved slowly to reduce inconvenience to the driver of the vehicle C. For example, the M mark may be moved at about 2 cycles / second. According to the first example, in a state where there is a problem that the pedestrian 71 and / or the other vehicle 72 approaches the vehicle C, the mark M which is the longitudinal bar is displayed while being moved to the right and left. The dynamic display of the M mark attracts more visual attention from the pedestrian 71 or the other vehicle 72 (a driver of the other vehicle 72) than the static display of the mark M. Therefore, the pedestrian 30 71 and / or the driver of the other vehicle 72 easily notices that the vehicle C is approaching him. At the same time, the discomfort of the driver of the vehicle C can be reduced during driving because the display is made intermittently. On the other hand, the 3024686 mark 21 in the form of a longitudinal bar M is displayed so as to move back and forth in the right and left directions. Therefore, the attention of the pedestrian 71 and / or the driver of the other vehicle 72 is intuitively attracted. Even if the mark M is traced with some deformation, an advantageous effect according to which the attention is attracted is not deteriorated. As shown in FIG. 8B, the vehicle display system 7 can turn off or lower the laser light in a portion of the predetermined area D. It is preferable that the vehicle display system 7 scans an area comprising a central portion of the travel path CR, i.e., a central portion of the predetermined area D, while stopping the laser light and the vehicle display system 7 turning on the laser light only in a state where the vehicle display system 7 scans an area comprising the left and right ends of the travel path CR, i.e. right and left portions 20 of the predetermined area D. Alternatively , the vehicle display system 7 turns on the laser light such that (i) an illumination intensity of the laser light in the central portion of the predetermined area D is lower than that of the laser light in the p left and right sides of the predetermined area D or (ii) a scanning speed in the central part of the predetermined area D is slower than that in the right and left parts of the predetermined area D. More specifically, the marks M indicated by the dashed lines are not displayed (or are displayed with reduced intensity) and M marks indicated by solid lines are displayed. Thus, the mark M becomes less visible for the driver of the vehicle C in an area in which the driver pays a great deal of attention. As a result, any strange sensation that a blink or equivalent can give the driver of the vehicle C can be reduced while the beneficial effect for the pedestrian 71 and the other vehicle 72 can still be maintained. The predetermined zone D is not limited to the CR channel. The predetermined zone D may be in the vicinity of other entities on the basis of the information obtained by the detection section of another entity 56.
    [0005] As shown in FIG. 8C, the predetermined area D can be provided to be at the foot of the pedestrian 71, and the mark M can be displayed dynamically in the predetermined area D. (Second example) [0047] The Fig. 9A is a diagram for explaining a second example of the vehicle display system 7. Fig. 9B illustrates a modification of the second example. In the second example, as shown in FIG. 9A, the predetermined area D is intended to be a rectangular longitudinal shape in the vehicle CR travel path C. In this case, a width of the predetermined area D in the Right and left directions and a length of the predetermined area D in the forward and reverse directions can be fixed or variable. For example, it is preferable that the predetermined zone D be set to be in a range of 10 meters to 50 meters in front of the vehicle C and to 3 meters wide. The vehicle display system 7 30 detects whether a pedestrian 71 and / or another vehicle 72 or not approaches the vehicle C and detects whether the vehicle C approaches an intersection 73. On the basis (i) information concerning the approach that is detected as soon as possible or (ii) information concerning one of the pedestrian 3024686 23 71, the other vehicle 72, and the intersection 73 which is determined to be in a state where it has the greatest warning need, the vehicle display system 7 displays the mark M in the predetermined area 5 D. The mark M is a side bar extending in the directions right and left in the predetermined region of longitudinal rectangular shape D. A sequential scan in the scanning zone SA is repeated to thus display the mark M in the predetermined region of longitudinal rectangular shape D while periodically moving the mark M in a single directio n from the back side to the front side. According to the second example, in a state where there is a problem that the pedestrian 71 and / or the other vehicle 72 approaches the vehicle C, the mark M which is the lateral bar is displayed while being moved forward. The dynamic display of the M mark attracts more visual attention to the pedestrian 71 or the other vehicle 72 (a driver of the other vehicle 72) than the static display of the M mark. Therefore, the pedestrian 71 and / or the driver of the other vehicle 72 easily notices that the vehicle C is approaching him. At the same time, the discomfort of the driver of the vehicle C can be reduced during driving because the display is made intermittently. In addition, the mark in the form of side bar M is displayed so as to move forward. Therefore, the attention of the pedestrian 71 and / or the driver of the other vehicle 72 is intuitively attracted. Even if the mark M is traced with some deformation, an advantageous effect according to which the attention is drawn is not deteriorated. In the second example, it is preferable that the vehicle display system 7 displays the mark M with a display speed (at which the mark 30 M is moved forward) which progressively increases towards a end before the predetermined zone D. Thus, the mark M is displayed with an increase in movement speed when the mark M 5 is farther from the vehicle C. Therefore, the pedestrian 71 and / or the driver of the other vehicle 72 are encouraged to pay attention to an early stage of approaching the vehicle C. [0051] In the second example, as shown in FIG. 9B, it is preferable that the vehicle display system 7 display the mark. in the form of a lateral bar M in order to have a greater width towards a rear end of the predetermined zone D. Thus, the pedestrian 71 and / or the driver of the other vehicle 72 can be aware of a distance up to 'veh icule C depending on the thickness of the bar. In the second example, the display speed of the mark M can be changed depending on a position of the pedestrian 71, that is to say if the pedestrian 71 20 is a pedestrian 71c crossing the path CR or pedestrian 71a walking along the CR track. In order to cause the pedestrian 71c to pay more attention, the vehicle display system 7 displays the M mark for the pedestrian 71c at a display speed higher than a display speed at which the mark M for the crossing pedestrian 71a is displayed. There is the problem of inadvertently causing an unnecessary sensation of excessive pressure by displaying the M mark for the pedestrian 71a at the same speed as the M mark for the crossing pedestrian 71c. As a result, the M mark for the crossing pedestrian 71c is displayed at a display speed corresponding to a speed at which the crossing pedestrian 71c is operating. (Third example) Fig. 10 is a diagram for explaining a third example of the vehicle display system 7. In the third example, as shown in Fig. 10, the predetermined area D has a 5 in the intersection 73 detected by the intersection detecting section 57. A range of the predetermined area D in this case may be fixed or variable. Upon detection of the intersection 73, the vehicle display system 7 displays the M mark having a spiral shape in the predetermined area D. Next, the sequential scan in the scan area SA is repeated to thereby display the mark M so that the mark M makes a circle from a center DO of the predetermined zone D to a lateral part DS of the predetermined zone D. In another example, the dynamic mark M can be displaced according to the displacement of the vehicle C. However, in the third example, the dynamic mark M can be displayed fixedly in the intersection 73 and not be moved according to the displacement of the vehicle C. In the third example, in a In a state where there is a problem that the pedestrian 71 and / or the other vehicle 72 approaches the vehicle C, the spiral mark M is displayed so as to dynamically spin. The dynamic display of the M mark attracts more visual attention to the pedestrian 71 or the other vehicle 72 (a driver of the other vehicle 72) than the static display of the mark M. Therefore, the pedestrian 71 and / or the driver of the other vehicle 72 easily notices that the vehicle C is approaching him. At the same time, the discomfort of the driver of the vehicle C can be reduced during driving because the display is made intermittently. On the other hand, the spiral mark M is displayed so as to spin. Therefore, even if the mark M is traced with some deformation, an advantageous effect according to which the attention is drawn is not deteriorated. The M mark may be a mark having a ripple pattern or a radiation pattern. [0055] (Other modified examples) It is preferable that the vehicle display system 7 executes the following command. That is, the vehicle display system 7 (i) causes the laser light source control unit 54 to reduce a lighting intensity of the laser light source unit 10 in an area in which the driver of the vehicle C pays close attention or (ii) increases a scanning speed of the scanning mechanism 11 in the area in which the driver of the vehicle C pays great attention, in order to adjust a quantity of such that the M mark is a slightly light-weighted part compared to one or more light distribution patterns formed by the headlight (light source units 5, 6). A luminance difference between the M mark and the light distribution pattern (s) is decreased. A contrast between the M mark and the light distribution pattern (s) formed by the lighthouse (the light source units 5, 6) is intentionally reduced. Thus, a strange sensation that the driver of the vehicle C may have may be further reduced. The mark M appears for the pedestrian 71 and the other vehicle 72 (the driver of the other vehicle 72) as being controlled in a more complex manner. Therefore, the pedestrian 71 and the other vehicle 72 (the driver of the other vehicle 72) notice the M mark earlier. As a result, the advantageous effect of attracting attention can be further increased. The examples and modifications described above of the dynamic display are merely examples of the invention. The respective examples and the respective modifications may be combined in different ways on the basis of the knowledge of one skilled in the art. It should be noted that examples of embodiments of the dynamic display obtained by such combinations are included within the scope of the invention. The vehicle display system 7 which dynamically displays the mark M uses, as the display device 8, the mechanism which scans with the laser light. However, the vehicle display system may use another mechanism / configuration.
    [0006] For example, an oscillating mechanism formed with a light passing hole having a shape of the M mark may be illuminated with the light source light, and the M mark may be mechanically tilted. Alternatively, several light sources can be sequentially lit.
