Further, the CPU 10 described above is an illumination canceling means for canceling the illumination of the switch 6 by the pilot lamp 4 when the possibility of operating the switch 6 is zero or low based on the determination result of the possibility determining section 11. (Fourth step S of the subroutine shown in FIG. 4)
24) and a plurality of illumination zones A, B, C, D, E,
Two or more lighting zones of F that are adjacent to each other (eg,
Zones A, B, and C) are adjacent to each other by the adjacency determination unit (see seventh step S7 of the main routine shown in FIG. 3) that determines whether or not the infrared sensor 5 is turned on, and the adjacency determination unit described above. When the infrared sensors 5 in two or more illumination zones are turned on, the superior illumination means that illuminates only the illumination zone on the side where the possibility of operating the switch 6 is high based on the determination result of the possibility determination section 11 (FIG. Refer to the fourth step S24 of the subroutine shown in FIG. 4, and this step S24 serves as both the illumination canceling means and the superior illumination means in this embodiment) and the only illumination based on the determination result of the possibility determining section 11 described above. When it is determined that only the infrared sensor 5 in the zone is turned on, the first prohibiting means for prohibiting the operation of the above-mentioned illumination canceling means (in the main routine of FIG. 11th step and S11 reference), when the infrared sensor 5 is determined to become ON in the illumination zone was mutually spaced by the adjacent determining unit, a second inhibiting means for inhibiting the operation of the illumination canceling means described above (Figure 3
11th step S11 in the main routine of
In this embodiment, step S11 also serves as the first and second prohibiting means).

Here, the cancel selection switch X in the operation unit 7 (see FIG. 2) described above is a selection means for operating the above-mentioned illumination cancellation means (see fourth step S24), and a non-cancel selection. The switch Y is a selection means for deactivating the illumination canceling means.

That is, each of these select switches X,
Y is configured to be selectable according to the occupant's preference,
In this embodiment, the cancel select switch X
The processing after the fourth step S4 in the flowchart of FIG. 3 is executed only when is turned ON.

Further, the mode switch M in the above-mentioned operation portion 7 is turned on according to the occupant's preference. When the mode switch M is ON, all the pilot lamps 4 in the corresponding zone in which the operability of the switch 6 is other than zero are turned on (all the possibilities are turned on), and the mode switch M = It is a selection means for turning on only the pilot lamps 4 in the corresponding zone where the switch 6 is likely to be operated (only those with a high possibility of being illuminated) when the switch 6 is off. The operation of the vehicle switch lighting device thus configured will be described in detail below with reference to the flowcharts shown in FIGS.

First, in a first step S1 of the main routine shown in FIG. 3, the CPU 10 reads a small lamp signal (a signal of the small lamp that is normally turned on only at night), and in a second step S2, the CPU 10 executes the reading. It is determined whether or not the small lamp is ON (at night) (including when traveling in a tunnel), and only when YES is determined, the process proceeds to the next third step S3. The nighttime determination may be executed by the output of the solar radiation sensor instead of the small lamp signal described above.

In the third step S3, the CPU 10 turns on the cancel select switch X and the non-cancel select switch Y in the operation unit 7 (see FIG. 2),
Performs OFF judgment and selects switch for cancellation X
Only when is ON, the process proceeds to the next fourth step S4. In the above-mentioned fourth step S4, the CPU 10 turns off all the pilot lamps 4a, 4b, 4c, 4d, 4e, 4f for night illumination in all the illumination zones A, B, C, D, E, F.

Next, in a fifth step S5, the CPU 10 determines whether or not at least one infrared sensor 5 in the illumination zones A, B, C, D, E, F has been turned ON, and when a NO determination is made (all When the infrared sensor 5 is off)
It is not necessary to illuminate the lighting zone in
While returning to step S4, when at least one infrared sensor 5 is turned on in response to the operation of the occupant (including the case where a plurality of infrared sensors 5 are turned on), the process proceeds to the next sixth step S6. Transition.

In the sixth step S6, the CPU 10 determines whether or not only one infrared sensor 5 is turned on,
When only one is turned on (when YES is determined), the following first
The process proceeds to step S11, and this eleventh step S11
Then, the CPU 10 turns on the pilot lamp 4 of the illumination with only one illumination zone in which the infrared sensor 5 is turned ON as a corresponding zone, and at the same time, starts the CPU built-in timer, and in the next twelfth step S12, the CPU 1
0 determines whether or not the timer has expired, in other words, whether or not the timer with built-in CPU has timed up, and when NO is determined, the first
While returning to step S11, Y of timer end
When the ES determination is made, the process returns to the fourth step S4. That is, when only one infrared sensor 5 is turned on, the pilot lamp 4 in the corresponding illumination zone lights up only for a certain period of time set by the timer, and the switch 6 in the corresponding illumination zone is illuminated. To do.

By the way, in the above-mentioned sixth step S6, O
When it is determined that there are a plurality of infrared sensors 5 having the number N, the process proceeds to the seventh step S7. In the seventh step S7, the CPU 10 determines whether or not the corresponding zones of the infrared sensors 5 that are turned on are two or more zones adjacent to each other, and when YES is determined (for example, three adjacent illumination zones A are adjacent to each other). , B, C infrared sensors 5a, 5b, 5c are both turned on), the process proceeds to the next eighth step S8, while a NO determination is made (for example, for two illumination zones A, F separated from each other). When both the infrared sensors 5a and 5f are turned on), the process proceeds to another tenth step S10.

In the tenth step S10, the CPU 10
Defines each lighting zone as the corresponding zone. For example, when the infrared sensors 5a and 5f of the illumination zones A and F are simultaneously turned on as described above, both of the two illumination zones A and F are set as the corresponding zones, and the following eleventh and twelfth steps are performed. By the processing of S11 and S12, the pilot lamps 4a and 4 of the respective illumination zones A and F are
f is turned on for a certain period of time set by a timer to illuminate the switches 6a and 6f in the respective illumination zones A and F.

On the other hand, in the above-described seventh step S7, it is determined that the corresponding zones of the plurality of turned-on infrared sensors 5 are two or more zones adjacent to each other (for example, illumination zones A, B, C). Sometimes, the process proceeds to the eighth step S8, and in the eighth step S8, the CPU 10 determines the operation condition according to a subroutine (see FIG. 4) described later, and then determines the illumination zone in the next ninth step S9 ( Determine the zone to be illuminated). After the illumination zone is determined in this ninth step S9, the pilot lamp 4 in the corresponding illumination zone is lit for a certain period of time set by a timer by the processing of the eleventh and twelfth steps S11 and S12 in the same manner as described above. Then, the switch 6 in the illumination zone is illuminated.

First step S of the subroutine shown in FIG.
At 21, the CPU 10 determines whether or not all the operability of the switches 6 in the two or more adjacent illumination zones in which the infrared sensor 5 is turned ON is high. For example, the infrared sensors 5a, 5 of the three lighting zones A, B, C adjacent to each other of the air conditioning zone A, the audio zone B, and the cigarette lighter zone C, respectively.
When both b and 5c are turned on, the switches 6a, 6b. It is determined whether or not all the operation possibilities for 6c are high.

Here, as an example of operability determination, if the radio receiver has good reception sensitivity, the operability is determined to be zero, and if the radio receiver has low reception sensitivity, The operability is determined to be "low", and when the reception sensitivity of the radio receiver is rapidly deteriorated, the operability is determined to be "high".

Further, when the wiper switch is ON (when it is raining), when the front defroster switch is ON (when the windshield is cloudy), when the temperature difference between the inside and outside air is more than a predetermined value (when the outside air temperature is low), and when the heater switch is ON (on the window). (When there is frost)
If any one of the conditions is satisfied, the operability of the switch 6d in the rear defogger zone D is determined to be “high”.

In this way, the possibility determining unit 11 determines whether the operability of the switch 6 of various vehicle-mounted devices is "high" or "low" based on the function state signal U or the vehicle surrounding information signal V.
It is judged in three stages of "zero".

When YES is determined in the first step S21, the process proceeds to the next second step S22, and in this second step S22, the CPU 10 determines that all the zones with high possibility of operation are to be illuminated. To do. For example, when the above infrared sensors 5a, 5b, 5c are both turned on, and the switch 6a, 6b, 6c is highly operable by the function state signal U and the ambient information signal V, three illumination zones A, B are provided. , C are all applicable zones to be illuminated.

On the other hand, NO in the above-mentioned first step S21.
At the time of determination, the process proceeds to another third step S23. For example, the infrared sensors 5a, 5b, 5c of three lighting zones A, B, C adjacent to each other of the air conditioning zone A, the audio zone B, and the cigarette lighter zone C are all turned on, and the respective lighting zones A, B, C are turned on. The operability for the switches 6a, 6b, 6c of the
If there is a low possibility of operation or zero among a, 6b, and 6c, the process proceeds to the third step S23.

In the third step S23, the CPU 10 determines whether or not the manipulability of which the manipulability is not high is zero, and when YES is determined, the CPU 10 proceeds to the fourth step S24.
When the O determination is made, the process proceeds to another fifth step S25.

For example, the switch 6 of the air conditioning zone A among the switches 6a, 6b and 6c of the above illumination zones A, B and C, respectively.
When the operability of a is high and the operability of each of the switches 6b and 6c of the audio zone B and the cigarette lighter zone C is zero, the process proceeds to the fourth step S24 and the lighting zones A, B and C are Switches 6a, 6b. If the operability of the switch 6a in the air conditioning zone A is high and the operability of the switches 6b and 6c in the audio zone B and the cigarette lighter zone C is low (not zero), the process proceeds to the fifth step S25. To do.

In the above-described fourth step S24, the CPU 10
Considers only the lighting zone of the switch that has high operability as the applicable zone. For example, as described above, the lighting zone A,
Among the switches 6a, 6b, 6c of B and C, the switch 6a of only the air conditioning zone A is highly likely to be operated, and the switches 6b of the audio zone B and the cigarette lighter zone C are
When the operability of 6c is zero, only the air conditioning zone A is set as the corresponding zone to be illuminated, and the other two illumination zones B and C are excluded from the corresponding zone in order to cancel the illumination.

In the above-mentioned fifth step S25, the CPU 10
Determines whether the mode switch M is ON. As described above, the mode switch M is selectively operated according to the occupant's preference. When the mode switch M = ON (YES
At the time of determination), all the pilot lamps 4 in the corresponding zone where the operability of the switch 6 is other than zero are turned on, and when the mode switch M = OFF (at the time of NO determination), the operability of the switch 6 is high. It is preset so that only the pilot lamp 4 in FIG.

Therefore, NO in the above-mentioned fifth step S25.
When the determination is made, the process proceeds to the fourth step S24, and when the YES determination is made, the process proceeds to another sixth step S26. For example, the switches 6a, 6b. 6c
Of the above conditions, the operability of the switch 6a of the air conditioning zone A is high and the operability of the switches 6b and 6c of the other two zones B and C are both low.
25, when the mode switch M = OFF, the process proceeds to the fourth step S24, and in this fourth step S24, the CPU 10 sets only the zone A with high operability as the corresponding zone, while the mode switch When M = ON, the process proceeds to the sixth step S26, and in this sixth step S26, the CPU 10 operates in all zones other than zero in the possibility of operation, that is, the air conditioning zone A, the audio zone B, and the cigarette lighter zone C (operation possible). Switch zones that have high operability and switch zones that have low operability) are all applicable zones.

The above-mentioned steps S22, S24,
The pilot lamp 4 of the lighting zone set in the corresponding zone to be illuminated in S26 is turned on only for a certain time set by the timer in the processing of steps S9, S11, S12 of the main routine shown in FIG. The switch 6 is illuminated. In short, a plurality of lighting zones A, B, C, which are grouped according to the functions of the in-vehicle device,
In D, E, F, these illumination zones A, B, C, D,
Illumination means for illuminating E and F exceptionally (pilot lamp 4
And a proximity sensor (see infrared sensor 5) for predicting and detecting the operation of the switch 6 in advance, so that the operation of the switch 6 provided in each of the illumination zones A, B, C, D, E, F can be performed. When the proximity sensor (see infrared sensor 5) detects in advance, the above illumination means (see pilot lamp 4) illuminates the switch 6, but the possibility determination unit 11 determines whether or not the switch 6 is operable. A determination is made based on the state signal U of the function of the device or the ambient information signal V of the vehicle, and the above-mentioned illumination canceling means (fourth step S
24) cancels the illumination of the switch 6 by the illumination means (see the pilot lamp 4) when the operability of the switch 6 is zero or low based on the determination result of the possibility determination unit 11. In this way, when the operability for the switch 6 is zero or low, the night illumination of the switch 6 by the illumination means (see the pilot lamp 4) is canceled, so that unnecessary illumination zones are prevented from being inadvertently illuminated. There is an effect that can be.

Further, the adjacency determining section (see the seventh step S7) uses the above-mentioned plurality of illumination zones A, B, C, D, E ,.
It is determined whether or not the proximity sensors (see infrared sensor 5) in two or more illumination zones adjacent to each other among F are turned on, and the superior illumination means (see fourth step S24).
When the proximity sensor (see infrared sensor 5) in two or more illumination zones adjacent to each other is turned on by the adjacency determination unit (see seventh step S7), the possibility determination unit 11 determines whether the proximity sensor is based on the determination result. The illumination zone on the side where the switch 6 is likely to be operated is illuminated. Therefore, each proximity sensor in two or more lighting zones (see infrared sensor 5)
When the switches 6 are turned on at the same time, only the illumination zone on the side where the switch 6 is likely to be operated is illuminated, and it is possible to prevent the illumination zone on the side where the switch 6 is less likely to be operated from being mistakenly illuminated. There is an effect that can be done.

Further, in the above-mentioned first prohibiting means (see the eleventh step S11), only the proximity sensor (see the infrared sensor 5) in the only illumination zone is turned on based on the determination result of the possibility determining section 11 described above. When it is determined that
The above-described operation of the illumination canceling means (see fourth step S24) is prohibited. That is, when only the proximity sensor (see the infrared sensor 5) in the only illumination zone is turned on and it is determined that the object to be operated by the occupant is the only illumination zone, the above-mentioned first prohibiting means (11th).
By prohibiting the illumination canceling operation in step S11), it is possible to illuminate the switch 6 in the only illumination zone that the occupant should switch, and prevent the illumination from being canceled against the occupant's intention. There is an effect that can be.

In addition, the above-mentioned second prohibiting means (see the eleventh step S11) is the same as the above-mentioned adjacent determining section (seventh step S11).
7), it is determined that the proximity sensor (see infrared sensor 5) in the illumination zones separated from each other is turned on, the above-mentioned illumination canceling means (fourth step S24).
(See) is prohibited. That is, when each of the proximity sensors (see the infrared sensor 5) in the illumination zones separated from each other is turned on, the second prohibiting means (first
In one step S11), the illumination canceling operation is prohibited, and the switches 6 in the respective illumination zones separated from each other are illuminated, thereby preventing the illumination from being canceled against the intention of the occupant. There is.

In the correspondence between the configuration of the present invention and the above-described embodiment, the illuminating means of the present invention corresponds to the pilot lamps 4a to 4f of the embodiment. Similarly, the proximity sensor is the infrared sensors 5a to 5f. The illumination canceling unit corresponds to the fourth step S24 of the subroutine controlled by the CPU 10, the adjacency determining unit corresponds to the seventh step S7 of the main routine controlled by the CPU 10, and the superior illumination unit is the subroutine of the CPU 10 control.
