Here, the control part 11 receives the input of the lighting location and lighting mode of the illumination lamp 2 which should be lighted according to the said distance from a user via the operation panel 32 of the navigation apparatus 3. FIG. Hereinafter, a process performed when the control unit 11 receives the input will be described.

  FIG. 4 is a flowchart showing the processing procedure of the interior lamp control device 1 when the setting relating to the lighting of the illumination lamp 2 is registered. The control unit 11 determines whether a setting operation request has been received (step S11). The setting operation request is a request for receiving an input of the lighting lamp 2 that is lit when the vehicle C is located near the destination or the memory point and the lighting mode in which the lighting lamp 2 is lit. The setting operation request is output to the control unit 11 by a user setting operation performed via the operation panel 32 of the navigation device 3. If it is determined that a setting operation request has not been received (S11: NO), the control unit 11 waits until a setting operation request is received.

  When it determines with having received the setting operation request | requirement (S11: YES), the control part 11 communicates with the navigation apparatus 3, and displays a control object selection screen on the display part with which the operation panel 32 is provided (step S12). The control target selection screen is an operation screen that receives an input of the electric lamp 2 that is lit when the vehicle C is located near the destination or the memory point. FIG. 5 is an explanatory diagram illustrating a specific example of the control target selection screen. FIG. 5 schematically shows the display unit of the operation panel 32 when the control target selection screen is displayed. The control target selection screen includes a display representing the electric lamp 2 that can be a control target, and a display that can identify whether the control target is selected as a control target such as a check box or a radio button. In the control object selection screen of FIG. 5, it is indicated that the door illumination lamp 22 including the foot illumination lamp 21 and the illumination lamp 2 that illuminates the door handle and the door pocket is selected as the control object.

  Then, the control part 11 determines whether the input from the control object selection screen was received (step S13). When it determines with not receiving the input (S13: NO), the control part 11 waits until an input is received. The control unit 11 functions as a control target receiving unit of the present invention by executing the control program 12a in step S13.

  When it determines with having received the input (S13: YES), the control part 11 memorize | stores the received input content in the temporary memory part 13 (step S14). The received input content is information on the lighting lamp 2 to be controlled that is input on the control target selection screen. For example, the information on the step lighting lamp 21 and the vicinity of the door handle in the door lighting lamp 22 are illuminated. This is information on the illumination lamp 2.

  Subsequently, the control part 11 displays a lighting pattern selection screen on the display part with which the operation panel 32 is provided (step S15). The lighting pattern selection screen is an operation screen that receives an input of a lighting mode of the lighting lamp 2 that is lit when the vehicle C is located near the destination or the memory point. FIG. 6 is an explanatory diagram illustrating a specific example of a lighting pattern selection screen. FIG. 6 schematically shows the display unit of the operation panel 32 when the lighting pattern selection screen is displayed. The lighting pattern selection screen includes a display that indicates a lighting mode that can be turned on by the electric lamp 2, and a display that can identify whether or not a lighting mode such as a check box or a radio button has been selected. In the control target selection screen of FIG. 6, it is shown that “Pattern A” is selected.

  Then, the control part 11 determines whether the input from the lighting pattern input screen was received (step S16). When it determines with not receiving the input (S16: NO), the control part 11 waits until an input is received. The control part 11 functions as a lighting mode reception part of the present invention by executing the control program 12a in step S16.

  When it determines with having received the input (S16: YES), the control part 11 matches the received lighting aspect and the lighting lamp 2 which should be made to light memorize | stored in the temporary storage part 13 by step S14, and is illuminated. Store in the table 12b (step S17). For example, when the user selects the electric lamp 21 and the electric lamp 2 that illuminates the vicinity of the door handle on the above-described control object selection screen for the home, and selects the pattern A on the above-described lighting pattern selection screen. The control unit 11 stores information corresponding to the selection in the illumination lamp table 12b. At this time, the control unit 11 stores one row in the illumination lamp table 12b so that the registration point, the lighting point, and the lighting mode are “home”, “foot, door handle”, and “pattern A”, respectively. Add information for.

  When the interior light control device 1 performs the above processing, the user can control the control target to be turned on based on the position information where the vehicle C is located via the setting screen described in FIGS. 5 and 6. It is possible to select a lighting mode for lighting a control target.

  FIG. 7 is a flowchart showing a processing procedure when the lighting of the electric lamp 2 is controlled by the interior light control device 1. The control unit 11 of the interior lamp control device 1 initializes the determination flag (step S21). The determination flag is a flag for identifying whether or not the lighting mode of the illumination lamp 2 has been determined by the lighting mode determination process in step S <b> 24 described later, and is stored in the temporary storage unit 13. The determination flag indicates that the lighting mode is determined when the value is 1, and indicates that the lighting mode is not determined when the value is any other value. In step S21, the control unit 11 initializes the determination flag to a value other than 1.

  Next, the control unit 11 determines whether or not it is at a communication timing to communicate with the navigation 3 (step S22). For example, the control unit 11 is configured to issue a command to the communication unit 14 so as to communicate with the navigation device 3 every predetermined time, and a communication timing at which communication with the navigation device 3 should be performed every time the predetermined time elapses. It is determined that The predetermined time is, for example, the same as the time for the navigation device 3 to acquire the position information at the position information receiving unit 31. When it determines with it not being in communication timing (S22: NO), the control part 11 waits until it becomes communication timing.

  When it determines with it being in communication timing (S22: YES), the control part 11 acquires the positional information on the vehicle C from the navigation apparatus 3 (step S23). The control unit 11 functions as a position information acquisition unit of the present invention by executing the control program 12a in step S23.

  Next, the controller 11 performs a lighting mode determination process (step S24). The lighting mode determination process is a process of determining a lighting mode to be lit on the electric lamp 2 based on the position information of the vehicle C acquired in step S23, and will be described in detail later.

  Thereafter, the control unit 11 determines whether or not the value of the determination flag is 1 (step S25). When it determines with the value of a determination flag not being 1 (S25: NO), the control part 11 returns a process to step S22.

  When it determines with the value of a determination flag being 1 (S25: YES), the control part 11 performs lighting control so that it may become the lighting aspect determined by step S24 (step S26). Next, the control unit 11 determines whether an end operation has been received via the operation panel 32 (step S27). The end operation is an operation for the control unit 11 to end the process of controlling the lighting of the illumination lamp 2 based on the position information of the vehicle C. For example, the driver performs the operation via the operation panel 32. Enter.

  When it is determined that the end operation has not been received (S27: NO), the control unit 11 returns the process to step S21, and when it is determined that the end operation has been received (S27: YES), the control unit 11 ends the process. .

  FIG. 8 is a flowchart showing the procedure of the lighting mode determination process. The control unit 11 of the interior lamp control device 1 reads position information of one registration point from the electrical lamp table 12b (step S31). For example, the control unit 11 reads home position information from the illumination lamp table 12b.

  Next, the control unit 11 calculates a distance based on the position information acquired in step S23 in FIG. 7 and the position information read in step S31 (step S32). For example, the control unit 11 calculates a linear distance between the positions represented by the position information based on the longitude and latitude coordinates representing the position information. The control unit 11 functions as a calculation unit of the present invention by executing the control program 12a in step S32.

  Here, in step S32, the control unit 11 may calculate the distance of the route from the position represented by the position information acquired in step S23 to the position represented by the position information read out in step S31. At this time, the control unit 11 can obtain and calculate information related to the route from the navigation device 3. Further, the control unit 11 may cause the navigation device 3 to calculate the distance of the route and acquire the calculation result from the navigation device 3. Furthermore, the interior light control device 1 and the navigation device 3 may be integrally configured, and the control unit 11 may perform processing corresponding to step S32 such as calculation of the distance of the route.

  After performing the process of step S32, the control part 11 determines whether the distance calculated by step S32 is below a 1st distance (step S33). The first distance is a distance representing the upper limit of the long-distance area, and is, for example, 500 m. When it determines with it not being below 1st distance (S33: NO), the control part 11 advances a process to step S40.

  When it determines with it being below 1st distance (S33: YES), the control part 11 determines whether the distance calculated by step S32 is below 2nd distance (step S34). The second distance is a distance representing the upper limit of the middle distance area, and is 200 m, for example. When it determines with it not being below 2nd distance (S34: NO), the control part 11 determines to a 1st lighting mode (step S35), and advances a process to step S39. The first lighting mode is a lighting mode when the calculated distance is in the long distance range.

  When it determines with it being below 2nd distance (S34: YES), the control part 11 determines whether the distance calculated by step S32 is below 3rd distance (step S36). The third distance is a distance representing the upper limit of the short-range area, and is 100 m, for example. When it determines with it not being below 3rd distance (S36: NO), the control part 11 determines to a 2nd lighting mode (step S37), and advances a process to step S39. The second lighting mode is a lighting mode when the calculated distance is in the middle distance range.
