  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this embodiment demonstrates the lamp | ramp automatic cut system which employ | adopted the illuminating device for vehicles of this invention.

(First embodiment)
FIG. 1 shows an overall configuration of a lamp auto cut system 10 mounted on a vehicle. The lamp automatic cut system 10 includes an input device 1, a navigation ECU 2, a body ECU 3, an AFS_ECU 4, and a headlamp 5 composed of two headlights arranged on the left and right sides of the front of the vehicle.

  The input device 1 is a device for a driver (user) of a vehicle to perform an input operation, and is disposed in the vicinity of an instrument panel of the vehicle. In the present embodiment, a case where a touch switch integrated with a display device connected to the navigation ECU 2 (input by touching the display screen) is adopted as the input device 1 will be described. The switch is not limited to a mechanical switch. The input device 1 outputs an input operation signal corresponding to a user's touch operation (input operation) to the navigation ECU 2.

  The navigation ECU 2 that is a control device of the car navigation system is configured as a microcomputer, and includes a well-known CPU, ROM, RAM, I / O, internal memory, and a bus line that connects these configurations. It has been. In the ROM, a program to be executed by the car navigation system is written, and a CPU or the like executes predetermined arithmetic processing according to this program.

  The navigation ECU 2 is connected to a display device provided with the touch switch described above, a position detector composed of a GPS (Global Positioning System) receiver, a map data input device (none of which is shown), and the like. A road map indicating the current position of the vehicle and a road map indicating the guide route are displayed on the display device, or a facility search is executed. The navigation ECU 2 functions as a display control device for the body ECU 3, and displays a lamp auto cut menu screen shown in FIG. 4 and a customization screen shown in FIG. 5 on the display device in accordance with a control signal from the body ECU 3.

  When the input operation signal is input from the input device 1 when FIG. 4 is displayed, the navigation ECU 2 determines which menu is selected from “user customization” and “user position”. Then, the customization information including the menu contents is output to the body ECU 3.

  Further, when the input operation signal is input from the input device 1 when FIG. 5 is displayed, the navigation ECU 2 determines the customization content corresponding to the input operation signal and includes the customization content. The customization information is output to the body ECU 3. Here, the customization screen shown in FIG. 5 will be described.

  On the customization screen shown in FIG. 5, it is possible to input the lighting direction and lighting time (lighting duration) of two headlights in lamp auto-cut control described later. The lighting direction of the two headlights is based on the front of the vehicle. When executing the lamp auto cut control, the right side of the headlight is changed to the left / right diagonally forward direction from the front of the vehicle. / Changed by touching a portion of the left headlight where "to the left" / "to the right" is displayed. Accordingly, in the lamp auto cut control, even when there are a plurality of ranges ahead of the vehicle that the user desires to illuminate, the lighting direction of the headlight can be changed to illuminate each range.

  In addition, the lighting times shown in FIG. 5 can be changed to the lighting times desired by the user by touching the places where “long” / “short” are displayed. In normal lamp auto-cut control, the headlights are turned on by receiving power from the vehicle battery, so the upper limit of lighting duration (about 30 seconds) is set in consideration of battery exhaustion. Yes. Therefore, it is desirable that the lighting time can be input within a range not exceeding the upper limit time. Further, by changing the lighting time to 0 seconds, only one of the two headlights can be turned on. Thereby, the electric power supplied from a vehicle-mounted battery can be suppressed.

  As described above, on the customization screen of FIG. 5, the customization content including the lighting direction and lighting time of each of the two headlights is input. Then, the navigation ECU 2 outputs customization information including the customization contents to the body ECU 3.

  The body ECU 3 is configured as a microcomputer, and has a well-known CPU, ROM, EEPROM (Electronically Erasable and Programmable Read Only Memory), RAM, I / O, internal memory, and a bus for connecting these configurations. A line is provided. In the EEPROM, whether or not lamp auto-cut is executed, the menu information described above, and customization information are written.

  When the execution of the lamp auto cut is set to “present”, the body ECU 3 turns the vehicle ignition switch and power switch “off” while the lighting / extinguishing switch of the headlamp 5 is “auto”. After that, when the door of the driver's seat of the vehicle is opened, the lamp auto cut control is performed so that the two headlights of the headlamp 5 are turned on until a predetermined time elapses and are automatically turned off when the predetermined time elapses. Execute.

  The body ECU 3 outputs a lamp auto-cut control signal (an on / off signal for the headlamp 5) according to the lighting time included in the customization information to the headlamp 5, so that the two headlights in the lamp auto-cut control are output. Controls turning on and off. Further, when the menu content included in the customization information is “user customization”, the body ECU 3 outputs the lighting direction information included in the customization information to the AFS_ECU 4.

  The AFS_ECU 4 is an AFS (Adaptive Front-Lighting System, “Light distribution variable type headlight” that improves the visibility by turning the headlight optical axis in the steering direction and turning on the vehicle traveling direction during cornering while the vehicle is running. Control system) (also called “light system”). The AFS_ECU 4 controls the optical axis direction of the headlight so that the traveling direction of the vehicle is lit while the vehicle is running, and during the lamp auto cut control when the vehicle is parked (customized information from the body ECU 3 (the headlight 5 When the lighting direction is input), the optical axis direction of the headlight is changed according to the customization information. The headlamp 5 has a drive mechanism that rotationally drives the optical axis directions of the two headlights in a horizontal plane.

  This drive mechanism is a known mechanism that drives the headlight to rotate within a predetermined angular range around a vertical rotation axis. The motor is electrically connected to the AFS_ECU 5 and controlled by the AFS_ECU 5, and the motor A worm gear that rotates integrally with the rotation shaft, and a worm wheel that is screw-engaged with the worm gear are provided. And it fixes to the worm wheel so that the rotating shaft of a headlight may rotate integrally with a worm wheel. With this drive mechanism, the optical axis directions of the two headlights can be adjusted independently of each other within a predetermined angle range (for example, ± 15 degrees).

  The AFS_ECU 4 generates a drive signal for driving the drive mechanism according to the customization information (lighting direction) and outputs the drive signal to the headlamp 5. As described above, the AFS includes a drive mechanism that rotationally drives the optical axis direction of the headlight of the headlamp 5 in a horizontal plane. By driving this drive mechanism, the lighting direction is set in the left-right direction of the vehicle. It becomes possible to change.

  Next, as shown in FIG. 2, the operation of the lamp auto-cut system 10 will be described on the assumption that the lighting direction of the two headlights at the time of lamp auto-cut control is changed (customized) to the right front side of the vehicle. To do. First, prior to the execution of the ramp auto cut control, the customization process shown in FIG. 3 is executed. Steps S11 to S13 of the customization process are executed by the body ECU 3 using an initial setting tool prepared separately.

  In step S11, it is determined whether or not to turn on the headlamp 5 when the driver gets off. Here, if an input indicating that the two headlights are to be turned on (indicating that lamp auto-cut control is to be executed) has been input from the initial setting tool, lamp auto-cut is present (lamp auto-cut is being performed) in step S12. ) And is written (stored) in the EEPROM of the body ECU 3 in step S13. On the other hand, if an input indicating that the two headlights are not to be turned on (indicating that lamp auto-cut control is not to be executed) has been input from the initial setting tool, this process ends.

  Subsequent processing from step S14 is executed by the body ECU 3 using the input device 1 and the navigation ECU 2. Note that the customization process of FIG. 3 may be executed from step S14 after the process from step S11 to step S13 using the initial setting tool is executed once.

  In step S14, it is determined whether or not it is desired to illuminate a range other than the front of the vehicle during the ramp auto cut control. Here, when the user performs an input operation to illuminate light other than the vehicle lighting from the input device 1, the process proceeds to step S15, and the user inputs a change in the lighting direction of the headlamp 5. Thus, in this embodiment, when the user desires to illuminate a diagonally forward direction of the vehicle other than the front of the vehicle, an input operation for changing the lighting direction is requested from the user. On the other hand, this process is complete | finished when a user performs input operation to the effect of illuminating vehicle illumination from the input device 1. FIG.

  In step S15, the lamp auto cut menu screen shown in FIG. 4 is displayed on the display device connected to the navigation ECU 2. In step S16, it is determined whether or not “1. User customization” has been selected from the menu displayed on the lamp auto cut menu screen. If it is determined that “1. User customization” is selected, the process proceeds to step S17. On the other hand, if it is determined that “2. User position” has been selected, customization information including the menu contents indicating that “User position” has been selected is written (stored) in the EEPROM of the body ECU 3 in step S19.

  In step S17, the customization screen shown in FIG. 5 is displayed on the display device connected to the navigation ECU 2. The user inputs the lighting direction and lighting time of each of the two headlights by touching the customization screen. For example, as shown in FIG. 2, when it is desired to light the vehicle's right diagonal forward direction for 15 seconds, the location where “to the right” is displayed so that the lighting direction of the left and right headlights is in the right direction. Touch to operate. Further, a touch operation is performed on a portion where “long” or “short” is displayed so that the lighting time of the left and right headlights is 15 seconds.

  In step S18, it is determined whether or not a touch operation has been performed on the portion displayed as “Determine” on the customization screen in FIG. 5, that is, whether or not the lighting directions and lighting times of the two headlights have been customized. If the determination is affirmative, customization information including the lighting direction and lighting time of each of the two headlights is written (stored) in the EEPROM of the body ECU 3 in step S19. On the other hand, if a negative determination is made, it is assumed that customization has not been completed, and the process returns to step S17.

  When the customization process of FIG. 3 is completed, the lamp auto-cut process (lamp auto-cut control) shown in FIG. 6 can be executed. Next, the lamp auto cut process shown in FIG. 6 will be described. First, when the user turns off the ignition switch of the vehicle while the on / off switch of the headlamp 5 is “auto”, whether or not the door of the driver's seat of the vehicle is opened in step S21. Judging. If the determination is affirmative, the process proceeds to step S22. If the determination is negative, the process ends.

  In step S22, it is read from the EEPROM of the body ECU 3 to determine whether or not “with lamp auto cut” is set. If the determination is affirmative, the process proceeds to step S23. If the determination is negative, the lamp auto cut control is not executed and the process is terminated.

  In step S23, it is determined whether or not customization is set, that is, whether or not customization information is written in the EEPROM of the body ECU 3. If an affirmative decision is made in step S23, the process of step S24 is executed, and if a negative decision is made, the process after step S26 is executed.

  In step S24, lighting is performed by changing the optical axis direction of each of the two headlights according to the lighting direction of each of the two headlights included in the customization information. In step S25, it is determined whether or not the lighting time has ended, that is, whether or not the time from the start of lighting has reached the lighting time included in the customization information. If an affirmative determination is made in step S25, the process proceeds to step S28. If a negative determination is made, the process returns to step S24.

  If a negative determination is made in step S23 (when customization is not set), the vehicle front direction is turned on in step S26. In step S27, it is determined whether or not the lighting time has ended, that is, whether or not the time from the start of lighting has reached a predetermined time (for example, 20 seconds). If an affirmative determination is made in step S27, the process proceeds to step S28. If a negative determination is made, the process returns to step S26. In step S28, the lighting of the headlight is finished (turned off).

  As described above, in the lamp auto-cut system 10 of the first embodiment, the user can customize the range (lighting direction) and lighting time that the user wants to illuminate during the lamp auto-cut control, and illuminates the customized lighting direction. The optical axis direction of each of the two headlights is changed. Thereby, when parking a vehicle at night or in a garage that does not have a lighting facility, it is possible to secure a field of view that the user wants to illuminate after getting off the vehicle.

Specifically, when the user position information is content indicating that the user is present on the right side of the vehicle, a drive signal for changing the optical axis direction of the headlamp is generated in the diagonally forward right direction of the vehicle. When the position information is content indicating that the user is present on the left side of the vehicle, a drive signal for changing the optical axis direction of the headlamp in the diagonally forward left direction of the vehicle is generated.

  Next, as shown in FIG. 8, when the user is present on the right side of the vehicle, it is assumed that the lighting direction of the two headlights during the ramp auto cut control is changed to the forward right diagonal direction of the vehicle. The operation of the cutting system 10 will be described. First, prior to the execution of the ramp auto cut control, the customization process shown in FIG. 3 is executed. Note that steps S11 to S15 in FIG. 3 are the same processing as the contents described in the first embodiment, and thus the description thereof is omitted.

  In step S16, it is determined whether or not "1. User customization" has been selected from the menu displayed on the lamp auto cut menu screen shown in FIG. If it is determined that “1. User customization” has been selected, the process proceeds to step S17. On the other hand, if it is determined that “2. User position” has been selected, the process proceeds to step S19. In this embodiment, assuming that “user position” has been selected, the process proceeds to step S19. In step S19, the customization information including the menu contents that the “user position” is selected is written (stored) in the EEPROM of the body ECU 3.

  When the customization process of FIG. 3 is completed, the lamp auto-cut process (lamp auto-cut control) shown in FIG. 10 can be executed. Next, the lamp auto cut process shown in FIG. 10 will be described. First, when the user turns off the ignition switch or the power switch of the vehicle while the on / off switch of the headlamp 5 is “auto”, the door of the driver's seat of the vehicle is opened in step S31. Determine whether it was done. If the determination is affirmative, the process proceeds to step S32. If the determination is negative, the process ends.

  In step S32, it is read from the EEPROM of the body ECU 3 to determine whether or not “with lamp auto cut” is set. If the determination is affirmative, the process proceeds to step S33. If the determination is negative, the lamp auto cut control is not executed, and the process ends.

  In step S33, it is determined whether a user position has been detected. If an affirmative determination is made in step S33, the process of step S34 is executed, and if a negative determination is made, the process after step S36 is executed.

  In step S34, according to the contents of the user information (that the user exists on the right / left side of the vehicle), the light axis directions of the two headlights are changed and turned on. In step S35, it is determined whether or not the lighting time has ended. If an affirmative determination is made in step S35, the process proceeds to step S38. If a negative determination is made, the process returns to step S34.

  If a negative determination is made in step S33 (when the user position is not detected), the vehicle front direction is turned on in step S36. In step S37, it is determined whether or not the lighting time has ended. If an affirmative determination is made in step S37, the process proceeds to step S38. If a negative determination is made, the process returns to step S36. In step S38, the lighting of the headlight is terminated (turned off).

  Thus, in the lamp auto cut system 10 of the second embodiment, the position of the user after the user gets off the vehicle is detected, and the range (lighting direction) to be illuminated during the lamp auto cut control is changed according to the user position. . Thereby, when parking a vehicle at night or in a garage that does not have a lighting facility, it is possible to secure a field of view that the user wants to illuminate after getting off the vehicle.
