  For example, as shown in FIG. 2, the indoor light 20 includes a dome lamp 21, a map lamp 22, a door courtesy lamp 23, and the like. The dome lamp 21 and the map lamp 22 are provided in the vicinity of the lamps 21 and 22. It is turned on or off according to the operation of the indoor light switches 21a and 22a.

  The indoor light switches 21a and 22a can be switched between two positions: off (lights off) and auto (for example, when the ignition switch IGSW is turned off and automatically turned on, and when the vehicle door lock is detected and automatically turned off). ing.

  The control circuit 30 (write control means) is composed mainly of a microcomputer in which a CPU 31, a RAM 32, a ROM 33, and an input / output unit (I / O) 34 are connected by an internal bus. The control circuit 30 is connected to the communication bus BUS via the communication interface IF1. Note that an ON / OFF signal of the ignition switch IGSW is input to the control circuit 30 via the communication bus BUS and the communication interface IF1. The ROM 33 stores a light control program for controlling the extinguishing operation of the outdoor light 10 as shown in FIG. 3, for example. The CPU 31 executes the control program stored in the ROM 33 using the RAM 32 as a work area.

  The navigation device NV is connected to the position detector 40, the transceiver 51, the operation switch group 52, the voice synthesis circuit 53 and the speaker 53a, the voice recognition unit 54 and the microphone 54a, the communication interface IF2, the hard disk device (HDD) 55, and the like. Control circuit 60 and the like.

  The position detector 40 functions as a current position detection unit of the host vehicle, and is a well-known geomagnetic sensor 41, a gyroscope 42 that detects the rotational angular velocity of the host vehicle, and a distance sensor that detects the travel distance of the host vehicle. 43 and a GPS receiver 44 that detects the position of the host vehicle based on radio waves from the satellite. Since these sensors 41 to 44 have errors of different properties, they are configured to be used while complementing each other.

  The transceiver 51 receives various types of information from the information center C as needed via an external wireless network. The operation switch group 52 includes, for example, a touch panel and a mechanical switch integrated with the display 52a. The voice recognition unit 54 and the microphone 54a are used for inputting various instructions by voice.

  The control circuit 60 is mainly configured by a microcomputer in which a CPU 61, a ROM 62, a RAM 63, an A / D conversion unit 64, a drawing unit 65, a nonvolatile memory 66, and an input / output unit (I / O) 67 are connected by an internal bus. . The CPU 61 performs control based on data in the navigation program 55 a and the database 55 b stored in the HDD 55, and controls reading / writing of data from / to the HDD 55. The A / D conversion unit 64 includes a well-known A / D (analog / digital) conversion circuit, and converts analog data input from the position detector 40 or the like to the control circuit 60 into digital data that can be calculated by the CPU 61, for example. . The drawing unit 65 generates display screen data to be displayed on the display 52a from display data and display color data stored in the HDD 55 or the like.

  In addition to the navigation program 55a, the HDD 55 stores so-called map matching data for improving the accuracy of position detection, and road map data 55c including road data representing road connections. The road map data 55c stores predetermined map image information for display, and road network information including link information (predetermined section information constituting each road) and node information (information defining a road branch point). Remember.

  The display 52a is formed of a known color liquid crystal display, and includes a dot matrix LCD (Liquid Crystal Display) and a driver circuit (not shown) for performing LCD display control. The driver circuit performs map display based on the display command and display screen data sent from the control circuit 60. At this time, the voice synthesis circuit 53 converts the digital voice data stored in the nonvolatile memory 66 or the HDD 55 into an analog voice according to a command from the navigation program 55a, and outputs the analog voice through the speaker 53a.

  When the navigation program 55a is activated by the CPU 61 of the control circuit 60, the navigation device NV selects the destination from the menu displayed on the display 52a by the operation of the operation switch group 52 or the voice input from the microphone 54a. When the route guidance process for setting and displaying the destination route on the display 52a is selected, the following process is performed.

  That is, when the user selects a point from a given point or facility search or address search on the map, a registered place set by the user, etc., and sets it as a destination, the current position of the host vehicle is obtained by the position detector 40, A process for obtaining an optimum guide route from the current position to the destination is performed. In addition, the guide route is displayed on the road map on the display 52a so as to guide the user to the appropriate route. When the host vehicle arrives at the set destination, a message to that effect is notified by at least one of the display 52a and the speaker 53a. The operation switch group 52, the microphone 54a, the navigation program 55a, and the like function as destination setting means.

  Next, the operation of the first embodiment configured as described above will be described. The CPU 31 of the control circuit 30 repeatedly executes the write control program of FIG.

  First, it is determined whether or not the destination is set by the operation switch group 52 or the microphone 54a of the navigation device NV (S11). When the destination is set (S11: Yes), the current position information of the host vehicle is acquired from the position detector 40 (S12, refer to FIG. 4A). If the destination is not set (S11: No), the execution of this write control program is temporarily terminated.

  Next, based on the current position information acquired in S12, it is determined whether or not the current position matches the destination (S13). For example, as shown in FIG. 4B, when the destination is set at home and the host vehicle arrives at the home, it is determined that the current position matches the destination position (S13: Yes), and the outdoor light 10 is It is determined whether it is in a lighting state (S14). If the outdoor light 10 is in a lighting state by operating the outdoor light switch 14 during night driving (S14: Yes), the outdoor light 10 is controlled to be turned off (S15). If the destination is set but the current position does not match the destination (S13: No), or if the current position matches the destination but the outdoor light 10 is not lit (S14: No), the execution of this write control program is once terminated.

  As is clear from the above description, in the first embodiment, when it is determined by the execution of the light control program of FIG. 3 that the current position of the host vehicle matches the destination of the host vehicle (S13: Yes). ), The outdoor light 10 in the lighting state is controlled to be turned off (S14: Yes, S15). Thus, if the navigation device NV mounted on the vehicle is used, the outdoor light 10 is automatically turned off when the host vehicle arrives at the destination only by setting the destination in advance. Thus, since the outdoor light 10 can be automatically turned off almost certainly by using the navigation device NV mounted on the vehicle, forgetting to turn off the outdoor light 10 can be satisfactorily prevented. In addition, since a special device is not required to be newly provided, the vehicle autolight device can be configured simply and inexpensively.

Second Embodiment In the second embodiment, the CPU 31 of the control circuit 30 is configured to repeatedly execute, for example, the write control program of FIG. 5 instead of the write control program of FIG. Since other configurations are the same as those in the first embodiment, the same reference numerals are given to step processes that perform the same functions, and descriptions thereof are omitted.

  The write control program of FIG. 5 is different from the write control program of FIG. 3 in that the process of step S21 is executed between steps S14 and S15. That is, when it is determined that the current position matches the destination (S13: Yes), the outdoor light 10 is turned on when the outdoor light 10 is in a lighting state (S14: Yes) and the ignition switch IGSW is on. Is maintained (S21: No), the outdoor light 10 is in a lighting state (S14: Yes), and the ignition switch IGSW is off, the outdoor light 10 is controlled to be turned off (S21). : Yes, S15).

  According to the second embodiment, the outdoor light 10 is controlled to be extinguished on the condition that the ignition switch IGSW is turned off, which is one of the conditions for getting off the user (S21: Yes, S15). Therefore, since the outdoor light 10 is not immediately turned off even when the host vehicle arrives at the destination, the uncomfortable feeling given to the user can be eliminated.

c. Third Embodiment In the third embodiment, the CPU 31 of the control circuit 30 is configured to repeatedly execute, for example, the write control program of FIG. 6 instead of the write control program of FIG. Since other configurations are the same as those in the first embodiment, the same reference numerals are given to step processes that perform the same functions, and descriptions thereof are omitted.

  The write control program of FIG. 6 is different from the write control program of FIG. 3 in that the process of steps S31 to S33 is executed instead of the process of step S15 of FIG. That is, when it is determined that the current position matches the destination (S13: Yes), if the outdoor light 10 is in a lighting state (S14: Yes), the outdoor light 10 is controlled to be turned off and the indoor light 20 is controlled to be turned on. (S31). In this case, the dome lamp 21 and the map lamp 22 are lit when the indoor light switches 21a and 22a are in the auto position. If a predetermined time has elapsed after the process of step S31 (a timer not shown starts timing), the indoor light 20 is controlled to be turned off (S32: Yes, S33).

  According to the third embodiment, when the own vehicle arrives at the destination, the indoor light 20 is automatically turned on (S31). For example, when searching for the room or preparing to get out after adjusting the room, etc. The convenience of the user can be improved. Moreover, since the lighting state of the indoor light 20 is canceled by the processing of steps S32 and S33, it is possible to satisfactorily prevent forgetting to turn off the automatically lit indoor light.

  In the third embodiment, the lighting state is released after a predetermined time has elapsed since the indoor light 20 is turned on. However, instead of the releasing means shown in step S32, For example, the lighting state of the indoor light 20 is determined by using the processing contents for detecting the operation of a door lock button in a wireless key switch or the operation of a door lock switch provided on an outside door handle in a vehicle adopting a smart key system as release means. You may comprise so that it may cancel | release.
