Furthermore, according to the vehicle information display device according to the third aspect of the present invention, when the display of the display items is switched in the head-up display, the cause of switching can be easily recognized by the vehicle occupant.

Hereinafter, a vehicle information display device according to an embodiment of the present invention will be described with reference to the accompanying drawings.
The vehicle information display device 10 according to the present embodiment includes a vehicle state sensor 11, a display device 12, and a processing device 13, for example, as shown in FIG.
Furthermore, the processing device 13 includes, for example, a priority comparison unit 21, a storage unit 22, and a display control unit 23.

  The vehicle state sensor 11 includes, for example, a vehicle speed sensor that detects the speed (vehicle speed) of the host vehicle, an acceleration sensor that detects acceleration acting on the vehicle body, and a gyro that detects the posture and traveling direction of the vehicle body. A positioning signal such as a sensor, a yaw rate sensor that detects the yaw rate (rotational angular velocity around the vertical axis of the center of gravity of the vehicle), or a GPS (Global Positioning System) signal for measuring the position of the vehicle using, for example, an artificial satellite For example, the receiver is configured to include a sensor for detecting various states such as a remaining amount of window washer fluid, a parking brake non-released state, and a seat belt non-wearing state.

The display device 12 is a head-up display that projects various display items using, for example, a predetermined region of a windshield of a vehicle as a display region, and includes a light source, a display, a mirror (not shown), and the like. In accordance with a control signal output from the display unit 13, a plurality of display items can be displayed superimposed on a single display area, and stimulus intensity (for example, luminance, area, color, etc.) of the plurality of display items can be displayed. The display items are switched by changing each item individually.
In the stimulus intensity, the increase and decrease in luminance are, for example, an increase and decrease in area, a change in color from green to yellow, yellow to red, and a change in color from red to yellow, yellow to green red, for example. , Corresponding to.

The priority comparison unit 21 of the processing device 13 refers to the correspondence between various vehicle information stored in advance in the storage unit 22 and display items in accordance with, for example, various vehicle information output from the vehicle state sensor 11. Then, the display items displayed in the display area of the display device 12 are acquired, and the display of the display device 12 is referred to by referring to the correspondence with the priorities of the plurality of display items stored in the storage unit 22 in advance. The priority of the display item already displayed in the area is compared with the priority of the display item newly displayed in the display area.
For example, as shown in FIG. 2, a display item of a window washer fluid remaining amount warning light A indicating that the remaining amount of window washer fluid is a predetermined amount or less, and a brake warning light indicating that the parking brake is not released. With respect to the display item B and the display item of the seat belt non-wearing warning lamp C indicating that the seat belt is not worn, the priority is set so as to sequentially increase.

Based on the comparison result by the priority comparison unit 21, the display control unit 23 performs display in the display area from a display item already displayed in the display area of the display device 12 to a display item newly displayed in the display area. Change the switching time required for switching.
For example, the display control unit 23 refers to the correspondence between the priority comparison results of the display items before and after the display switching stored in the storage unit 22 in advance and the switching time, and acquires the switching time. The display switching, that is, the change of the stimulus intensity (for example, luminance) of each display item is controlled according to.

As described above, according to the vehicle information display device 10 according to the present embodiment, when the display items in the display area of the display device 12 are switched, switching required for switching according to the priority of the display items before and after switching. The time is changed.
As a result, for example, as in the comparative example shown in FIG. 3A, the switching time TE is set to zero regardless of the priority of the display items before and after switching, and the remaining amount of window washer fluid at an appropriate time te. For example, as shown in FIG. 3B, the luminance of the warning light A is changed from the predetermined maximum luminance CM to zero and the luminance of the brake warning light B is changed from zero to the predetermined maximum luminance CM. As in the embodiment, the switching time TE is set to an appropriate time tb according to the comparison result of the priorities of the display items before and after switching, and the window washer liquid is passed from the appropriate switching start time tb1 to the switching end time tb2. The luminance of the remaining amount warning light A is gradually changed from the predetermined maximum luminance CM to zero, and the luminance of the brake warning light B is gradually changed from zero to the predetermined maximum luminance CM. More, it is possible to recognize accurately and intuitively the occupant of the vehicle to change the priority of display items before and after the switching.

Below, the 1st modification of embodiment mentioned above is demonstrated.
In the first modification, the storage unit 22 stores, for example, an individual switching time set for each display item according to the priority, as shown in FIG. 4, and the display control unit 23 is displayed in the display area. The switching time is set based on the individual switching time of the newly displayed display item, and the display item display is switched in the display area.
For example, in FIG. 4, the individual switching time is set so as to be shortened as the priority increases, and the window washer liquid remaining amount warning light A, the brake warning light B, and the seat belt non-switching are set. Individual switching times ta, tb, and tc (ta>tb> tc) are sequentially set for the wear warning lamp C according to the priorities pa, pb, and pc (pa <pb <pc). .

Accordingly, for example, as shown in FIG. 5A, when the display item is switched from the window washer fluid remaining amount warning light A to the brake warning light B, it is set for the brake warning light B that is newly displayed. The stimulation intensity, for example, the brightness of the window washer fluid remaining amount warning light A and the brake warning light B is changed by the individual switching time tb, and the switching time tb2 (tb2-tb1 = tb) from the appropriate switching start time tb1. Thus, the brightness of the window washer liquid remaining amount warning light A is gradually changed from the predetermined maximum brightness CM to zero, and the brightness of the brake warning light B is gradually changed from zero to the predetermined maximum brightness CM.
Further, for example, as shown in FIG. 5B, when the display item is switched from the brake warning light B to the seat belt non-wearing warning light C, it is set for the newly displayed seat belt non-wearing warning light C. The stimulation intensity, for example, the brightness of the brake warning light B and the seat belt non-wearing warning light C is changed by the individual switching time tc, and the appropriate switching start time tc1 to switching end time tc2 (tc2-tc1 = tc). The brightness of the brake warning light B is gradually changed from the predetermined maximum brightness CM to zero, and the brightness of the non-seat belt warning light C is gradually changed from zero to the predetermined maximum brightness CM.

  According to the first modification, since the switching time required for switching is set based on the individual switching time according to the priority of the display item to be newly displayed, the priority of the display item before and after the switching is It is possible to make the vehicle occupant accurately and intuitively recognize whether the vehicle rises or falls.

Below, the 2nd modification of embodiment mentioned above is demonstrated.
In the second modification, the storage unit 22 stores the individual switching time set for each display item according to the priority, as shown in FIG. 4, for example, as in the first modification described above. .
And the display control part 23 changes irritation | stimulation intensity | strength according to individual switching time for every display item.

For example, as shown in FIG. 6A, when the switching of the display item from the window washer fluid remaining amount warning light A to the brake warning light B is started from an appropriate switching start time t1, the window washer fluid remaining amount warning light is displayed. In A, the luminance is gradually changed from the predetermined maximum luminance CM to zero in a period over the individually set individual switching time ta (that is, a period from the switching start time t1 to time t3 (= t1 + ta)), and The brake warning light B gradually increases from zero to a predetermined maximum luminance CM in a period over an individually set individual switching time tb (that is, a period from switching start time t1 to time t2 (= t1 + tb)). Be changed.
When the switching of the display item from the brake warning light B to the seat belt non-wearing warning light C is started from an appropriate switching start time t4, the brake warning light B is set for an individually set individual switching time tb. In the period (that is, the period from the switching start time t4 to the time t6 (= t4 + tb)), the luminance is gradually changed from the predetermined maximum luminance CM to zero, and the seat belt non-wearing warning lamp C is individually set. The luminance is gradually changed from zero to a predetermined maximum luminance CM in a period over the individual switching time tc (that is, a period from switching start time t4 to time t5 (= t4 + tc)).

For example, as shown in FIG. 6B, when switching of the display item from the seat belt non-wearing warning light C to the brake warning light B is started from an appropriate switching start time t1, the seat belt non-wearing warning light In C, the luminance is gradually changed from the predetermined maximum luminance CM to zero in a period over an individually set individual switching time tc (that is, a period from switching start time t1 to time t2 (= t1 + tc)), and The brake warning light B gradually increases from zero to a predetermined maximum luminance CM in a period over an individually set individual switching time tb (that is, a period from switching start time t1 to time t3 (= t1 + tb)). Be changed.
Further, when the switching of the display item from the brake warning light B to the window washer fluid remaining amount warning light A is started from the appropriate switching start time t4, the brake warning light B is set to the individually set individual switching time tb. The luminance is gradually changed from the predetermined maximum luminance CM to zero in the extended period (that is, the period from the switching start time t4 to the time t5 (= t4 + tb)), and the window washer liquid remaining amount warning lamp A is individually set. The luminance is gradually changed from zero to the predetermined maximum luminance CM in the period over the individual switching time ta (that is, the period from the switching start time t4 to the time t6 (= t4 + ta)).

  According to the second modification, the stimulus intensity is changed for each display item based on the individual switching time corresponding to the priority for each display item. It is possible to make the vehicle occupant accurately and intuitively recognize whether the vehicle rises or falls.

  In the second modification described above, for example, as in the third modification shown in FIGS. 7A and 7B, a display item having a relatively high priority is displayed in the display area according to the individual switching time. When displayed, display in a display area of a display item having a relatively low priority may be prohibited regardless of the individual switching time of the display item having a relatively low priority.

For example, as shown in FIG. 7 (a), display items from a window washer liquid remaining amount warning light A having a relatively low priority from an appropriate switching start time t1 to a brake warning light B having a relatively high priority. When switching is started, display of the window washer liquid remaining amount warning light A is prohibited regardless of the individually set individual switching time ta, and the brake warning light B is individually set to the individual switching time tb. The luminance is gradually changed from zero to a predetermined maximum luminance CM in a period extending over (that is, a period from the switching start time t1 to time t2 (= t1 + tb)).
In addition, when switching of the display item from the brake warning light B having a relatively low priority to the seat belt non-wearing warning light C having a relatively high priority is started from an appropriate switching start time t4, the brake warning light is started. B is prohibited from being displayed regardless of the individually set individual switching time tb, and the seat belt non-wearing warning lamp C is set to a period over the individually set individual switching time tc (that is, the time from the switching start time t4). The luminance is gradually changed from zero to a predetermined maximum luminance CM during a period of time t5 (= t4 + tc)).

In addition, for example, as shown in FIG. 7B, the display items for the brake warning light B having a relatively low priority from the seat belt non-wearing warning light C having a relatively high priority from the appropriate switching start time t1. When the switching is started, the brightness of the seat belt non-wearing warning lamp C is increased in a period over an individually set individual switching time tc (that is, a period from the switching start time t1 to time t2 (= t1 + tc)). The predetermined maximum brightness CM is gradually changed to zero.
The brake warning light B has a luminance from zero to a predetermined maximum luminance CM in a period over an individually set individual switching time tb (that is, a period from switching start time t1 to time t3 (= t1 + tb)). Although it is gradually changed, the display is performed regardless of the individual switching time tb during the period in which the seat belt non-wearing warning light C is displayed (that is, the period from the switching start time t1 to the time t2 (= t1 + tc)). Display is permitted only during a period from time t2 when display of the seatbelt non-wearing warning lamp C ends to time t3 (= t1 + tb).
When the switching of the display item from the appropriate warning start time t4 to the relatively low priority brake warning light B to the relatively low priority window washer fluid remaining warning light A is started, the brake warning is issued. In the lamp B, the luminance is gradually changed from the predetermined maximum luminance CM to zero in a period over the individually set individual switching time tb (that is, a period from the switching start time t4 to the time t5 (= t4 + tb)). .
The window washer liquid remaining amount warning lamp A has a luminance from zero to a predetermined maximum in a period over an individually set individual switching time ta (that is, a period from switching start time t4 to time t6 (= t4 + ta)). Although it is gradually changed to the luminance CM, it is displayed regardless of the individual switching time ta during the period when the brake warning light B is displayed (that is, the period from the switching start time t4 to the time t5 (= t4 + tb)). Is prohibited, and display is permitted only in a period from time t5 when display of the brake warning light B is ended to time t6 (= t4 + ta).

Below, the 4th modification of embodiment mentioned above is demonstrated.
In the fourth modified example, the storage unit 22 corresponds to the correspondence between the comparison result of the priority of the display items before and after the display switching and the switching time, for example, as in the second to fifth embodiments shown in FIG. In addition, the correspondence relationship between the priority comparison results of the display items before and after the display switching and the switching mode is stored.
Then, based on the comparison result by the priority comparison unit 21, the display control unit 23 changes the display item from the display item already displayed in the display region of the display device 12 to the display item newly displayed in the display region. Switching which is a method of switching display in the display area from the display item already displayed in the display area of the display device 12 to the display item newly displayed in the display area while changing the switching time required for display switching Change the aspect.

For example, in the second embodiment shown in FIG. 8, when the display item is switched from the relatively low priority window washer fluid remaining amount warning light A to the relatively high priority seat belt non-wear warning light C, After the time t2 when the brightness of the washer liquid remaining warning light A reaches zero and the brightness of the seat belt non-wearing warning light C reaches the predetermined maximum brightness CM, the brightness of the non-seat belt warning light C is temporarily increased. Therefore, the predetermined maximum luminance CM is increased.
On the other hand, when the display item is switched from the relatively high priority seatbelt non-wearing warning light C to the relatively low priority window washer liquid remaining warning light A, the brightness of the non-seatbelt warning light C is increased. After the time t2 when the brightness of the window washer liquid remaining amount warning light A has reached the predetermined maximum brightness CM after reaching zero, the brightness of the window washer liquid remaining amount warning lamp A is temporarily set to be higher than the predetermined maximum brightness CM. Reduce.

Further, for example, in the third embodiment shown in FIG. 8, at the time of switching the display item from the window washer liquid remaining amount warning light A having a relatively low priority to the seat belt non-wearing warning light C having a relatively high priority. The brightness of the window washer liquid remaining amount warning light A is gradually changed from the predetermined maximum brightness CM to zero, and the brightness of the seat belt non-wearing warning light C is gradually changed from zero to the predetermined maximum brightness CM. In the period from time t1 to time t2, the brightness of the seat belt non-wearing warning lamp C is temporarily increased to a predetermined brightness.
On the other hand, when the display item is switched from the relatively high priority seatbelt non-wearing warning light C to the relatively low priority window washer liquid remaining warning light A, the brightness of the non-seatbelt warning light C is increased. In a period from time t1 to time t2 when the predetermined maximum brightness CM is gradually changed to zero and the brightness of the window washer liquid remaining amount warning lamp A is gradually changed from zero to the predetermined maximum brightness CM. The brightness of the window washer liquid remaining amount warning lamp A is temporarily reduced to a predetermined brightness.

Further, for example, in the fourth embodiment shown in FIG. 8, at the time of switching the display item from the window washer liquid remaining amount warning light A having a relatively low priority to the seat belt non-wearing warning light C having a relatively high priority. The brightness of the window washer liquid remaining amount warning light A is gradually changed from the predetermined maximum brightness CM to zero, and the brightness of the seat belt non-wearing warning light C is gradually changed from zero to the predetermined maximum brightness CM. In the period from the time t1 to the time t2, it is necessary for the luminance of the non-seat belt warning light C and the luminance of the window washer liquid remaining warning light A to reach a half value of the predetermined maximum luminance CM. Reduce time.
On the other hand, when the display item is switched from the relatively high priority seatbelt non-wearing warning light C to the relatively low priority window washer liquid remaining warning light A, the brightness of the non-seatbelt warning light C is increased. In a period from time t1 to time t2 when the predetermined maximum brightness CM is gradually changed to zero and the brightness of the window washer liquid remaining amount warning lamp A is gradually changed from zero to the predetermined maximum brightness CM. The time required for the brightness of the non-seat belt warning light C and the brightness of the window washer liquid remaining warning light A to reach a value half of the predetermined maximum brightness CM is extended.

Further, for example, in the fifth embodiment shown in FIG. 8, when the display item is switched from the window washer liquid remaining amount warning light A having a relatively low priority to the seat belt non-wearing warning light C having a relatively high priority. The brightness of the window washer liquid remaining amount warning light A is gradually changed from the predetermined maximum brightness CM to zero, and the brightness of the seat belt non-wearing warning light C is gradually changed from zero to the predetermined maximum brightness CM. In the period from time t1 to time t2, the brightness and window of the seat belt non-wearing warning light C at the time when the brightness of the seat belt non-wearing warning light C and the brightness of the window washer liquid remaining warning light A are switched. The brightness of the washer liquid remaining amount warning lamp A is lowered to a value that is 1/2 of the predetermined maximum brightness CM.
On the other hand, when the display item is switched from the relatively high priority seatbelt non-wearing warning light C to the relatively low priority window washer liquid remaining warning light A, the brightness of the non-seatbelt warning light C is increased. In a period from time t1 to time t2 when the predetermined maximum brightness CM is gradually changed to zero and the brightness of the window washer liquid remaining amount warning lamp A is gradually changed from zero to the predetermined maximum brightness CM. The brightness of the seat belt non-wearing warning light C and the brightness of the window washer fluid remaining warning light A at the time when the brightness of the seat belt non-wearing warning light C and the brightness of the window washer liquid remaining warning light A are switched. , More than a value of 1/2 of the predetermined maximum brightness CM.

The above-described embodiment and the first to fourth modifications may be combined as appropriate. For example, as shown in FIG. 9, the first modification described in the second embodiment in the fourth modification is described. When combined with the example, when the display item is switched from the window washer fluid remaining amount warning light A to the brake warning light B, the individual switching time tb set for the newly displayed brake warning light B is used. The stimulus intensity, for example, luminance, of the window washer fluid remaining amount warning light A and the brake warning light B is changed, and the window washer fluid remaining amount warning light A is changed from time t2 to time t3 (t3−t2 = tb). The luminance is gradually changed from the predetermined maximum luminance CM to zero, and the luminance of the brake warning light B is gradually changed from zero to the predetermined maximum luminance CM. Then, after the time t3 when the brightness of the window washer liquid remaining warning light A reaches zero and the brightness of the brake warning light B reaches the predetermined maximum brightness CM, the brightness of the brake warning light B is temporarily predetermined. It is increased more than the maximum brightness CM.
Further, when the display item is switched from the brake warning light B to the seat belt non-wearing warning light C, the brake warning light B is set according to the individual switching time tc set for the newly displayed seat belt non-wearing warning light C. The stimulation intensity, for example, the luminance of the non-seat belt warning light C is changed, and the luminance of the brake warning light B changes from the predetermined maximum luminance CM to zero from time t4 to time t5 (t5-t4 = tc). And the brightness of the warning light C not wearing the seat belt is gradually changed from zero to a predetermined maximum brightness CM. Then, after time t5 when the brightness of the brake warning light B reaches zero and the brightness of the non-seat belt warning light C reaches the predetermined maximum brightness CM, the brightness of the non-seat belt warning light C temporarily To a predetermined maximum brightness CM.
Further, when the display item is switched from the seat belt non-wearing warning light C to the brake warning light B, the seat belt non-wearing warning light C is set according to the individual switching time tb set for the newly displayed brake warning light B. The stimulation intensity, for example, the brightness of the brake warning light B is changed, and the brightness of the non-seat belt warning light C is changed from the predetermined maximum brightness CM to zero from time t6 to time t7 (t7−t6 = tb). And the brightness of the brake warning light B is gradually changed from zero to a predetermined maximum brightness CM. Then, after the time t7 when the brightness of the non-seat belt warning light C reaches zero and the brightness of the brake warning light B reaches the predetermined maximum brightness CM, the brightness of the brake warning light B is temporarily set to the predetermined maximum. The luminance CM is lowered.
Further, when the display item is switched from the brake warning light B to the window washer fluid remaining amount warning light A, the brake warning is performed by the individual switching time ta set for the newly displayed window washer fluid remaining amount warning light A. The stimulation intensity, for example, the luminance of the lamp B and the window washer liquid remaining amount warning lamp A is changed, and the luminance of the brake warning lamp B is set to the predetermined maximum luminance CM from time t8 to time t9 (t9-t8 = ta). The brightness of the window washer liquid remaining amount warning lamp A is gradually changed from zero to a predetermined maximum brightness CM. Then, after the time t9 when the brightness of the brake warning light B reaches zero and the brightness of the window washer fluid remaining warning light A reaches the predetermined maximum brightness CM, the brightness of the window washer fluid remaining warning light A is increased. It is temporarily increased beyond the predetermined maximum brightness CM.

  According to the fifth modified example, when the display item is switched, the priority of the display item before and after switching is changed by changing the switching mode (for example, change in luminance with time) according to the priority of the display item before and after switching. It is possible to make the vehicle occupant accurately and intuitively recognize whether the degree increases or decreases.
