Flashes, the owner can be alerted, and the security against theft and the like can be improved.

(Embodiment 4) FIG. 5 shows Embodiment 4 of the present invention.
The door mirror lamp 22 arranged on the side closer to the owner of the vehicle is turned on with a higher illuminance than the door mirror lamp 22 arranged on the side opposite to the approach direction side. The hardware configuration of the fourth embodiment is the same as that of the first embodiment.

That is, in the first step SD1, it is determined whether or not a user authentication signal whose reception strength is greater than the set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. In some cases, the process proceeds to step SD2 to determine whether or not the lane change assist camera 24 on the driver's seat side has detected a person on the driver's seat side of the vehicle.

If the determination in step SD2 is YES, the process proceeds to step SD3, in which the door mirror lamps 22 are turned on, and the driver's side door mirror lamp 22 is turned on with a higher illuminance than the passenger's seat side. And
In the next step SD4, the door knob switch 19
It is determined whether or not contact with the knob of the driver's door has been detected. When the determination in step SD4 is NO, the operation in step SD4 is repeated, and when the determination is YES, the process proceeds to step SD8.

When the determination in step SD2 is NO, the process proceeds to step SD5, in which it is determined whether a lane change assist camera 24 on the passenger seat detects a person on the passenger seat side of the vehicle. Then, this step SD5
If the determination is NO, the process returns as it is, while if the determination is YES, the process proceeds to step SD6, where both door mirror lamps 22 are turned on, and the passenger side door mirror lamp 22 is turned on at a higher illuminance than the driver seat side. Turn on. Then, in the next step SD7, it is determined whether or not the door knob switch 19 has detected the contact of the knob of the driver's door, and the determination in step SD7 is NO.
Is satisfied, the operation of step SD7 is repeated, while if the determination is YES, the process proceeds to step SD8.

In step SD8, the lit door mirror lamp 22 is turned off, and the process returns.

When the owner of the vehicle approaches the vehicle from the driver's seat side by the signal processing operation of the CPU 16 of the on-vehicle device 15, the driver's seat side door mirror lamp 22 arranged in the approach direction side is turned on. Lighting control is performed with priority over the passenger side door mirror lamp 22.
Specifically, the driver's seat side door mirror lamp 22 is turned on with higher illuminance than the passenger's seat side. On the other hand, when the owner of the vehicle approaches the vehicle from the passenger seat side, the passenger side door mirror lamp 22 arranged on the approach direction side is turned on with higher illuminance than the driver seat side. When the hand of the owner of the vehicle contacts the knob of the driver's seat door, the lit door mirror lamp 22 is turned off.

In the fourth embodiment, the lane change support camera 24 detects the behavior of the vehicle owner regarding the approach or separation from the vehicle and the direction of approach of the vehicle owner to the vehicle. Approach direction detecting means.

Therefore, in the fourth embodiment, when a user authentication signal having a reception intensity higher than the set value is received, both door mirror lamps 22 are turned on, but the door mirror lamp 22 in the approach direction is moved to the opposite side. Since the lighting is performed with high illuminance prior to the door mirror lamp 22, it is possible to further improve the convenience of the vehicle owner while suppressing the consumption of the battery, as in the first embodiment.

(Embodiment 5) FIG. 6 shows Embodiment 5 of the present invention.
In place of the door mirror lamp 22 in the first to fourth embodiments, a roof lamp 27 for irradiating the driver's seat side is provided on the side of the roof rail on the driver's seat side of the left and right roof rails of the vehicle. The direction is directed to the approaching direction of the vehicle owner.

That is, in the fifth embodiment, the illumination direction of the roof lamp 27 can be changed by a lamp drive actuator 28 within a predetermined range on the driver's seat side (within a detection range of a position detection sensor described later). Have been. At the same position as the roof lamp 27, 1
A position detection sensor 29 is provided which comprises a pair of ultrasonic sensors and detects the distance to the owner present on the driver's seat side and the direction in which the owner exists. Thus, instead of the lane change support camera 24 in the first to fourth embodiments, the position detection sensor 29 includes an action detection unit that detects an action related to the approach or separation of the vehicle owner from the vehicle, And the approach direction detecting means for detecting the approach direction of the owner of the vehicle to the vehicle. The in-vehicle device 15 drives the lamp drive actuator 28 so that the irradiation direction of the roof lamp 27 is directed to the direction in which the owner is detected by the position detection sensor 29.

Hereinafter, the signal processing operation performed by the CPU 16 of the on-vehicle device 15 will be described in detail with reference to FIG.

First, in the first step SE1, it is determined whether or not a user authentication signal having a reception strength larger than a set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. In some cases, the process proceeds to step SE2, where it is determined whether the position detection sensor 29 has detected an owner within the detection range.

When the determination in step SE2 is NO, the process returns as it is, while when the determination is YES, the process proceeds to step SE3, where the roof lamp 2
Then, in step SE4, the lamp drive actuator 28 is driven to irradiate the roof lamp 27 in the direction and distance in which the owner is detected. That is,
The irradiation direction of the roof lamp 27 is changed so that the road surface on the front side in the traveling direction of the owner is illuminated. Then, in the next step SE5, it is again determined whether or not the owner has been detected within the detection range by the position detection sensor 29. When the determination in step SE5 is YES, the process returns to step SE4. If the determination is NO, the process proceeds to step SE6, where the roof lamp 27 is turned off and the process returns.

When the owner of the vehicle approaches the vehicle from the driver's seat side and enters the detection range of the position detection sensor 29 by the signal processing operation of the CPU 16 of the vehicle-mounted device 15, the roof lamp 27 is turned on. At the same time, the irradiation direction of the roof lamp 27 is directed to the direction in which the owner exists, and even if the owner moves, the irradiation direction is always directed to the direction in which the owner exists. When the owner goes out of the detection range of the position detection sensor 29 (eg, gets into the vehicle),
The roof lamp 27 turns off.

Therefore, in the fifth embodiment, the irradiation direction of the roof lamp 27 is directed toward the approaching direction of the vehicle owner, so that the front side of the traveling direction of the vehicle owner is reliably illuminated, and the convenience of the owner is improved. Properties can be further improved.

(Embodiment 6) FIG. 8 shows Embodiment 6 of the present invention.
The portable device 1 transmits an unlock signal (identification signal) for unlocking the lock of the vehicle door from the transmitter 11 for a predetermined period (for example, instead of the user authentication signal in the first to fifth embodiments). 0.5 to 1 second), and the receiver 26 and the CPU 16 of the on-vehicle device 15 are connected to the lane change support camera 24 in the first to fourth embodiments and the position detection in the fifth embodiment. Instead of the sensor 29, an action detecting means for detecting an action of the owner of the vehicle toward or away from the vehicle is configured.

In the sixth embodiment, the vehicle-mounted device 15
When the unlock signal is received by the receiver 26 and the reception strength is greater than the set value, the door lock actuator 23 is unlocked to unlock the door lock and the door mirror lamp 22 And when the unlock signal is received and the behavior detecting means detects that the owner of the vehicle is moving away from the vehicle, the door mirror lamp 22 is prohibited from being turned on and turned off.

First, in the first step SF1, it is determined whether or not an unlocking signal having a reception strength greater than the set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. Sometimes step SF
In step 2, the door lock actuator 23 is unlocked to unlock the door, and the door mirror lamp 22 is turned on. In the next step SF 3, the communication between the owner and the vehicle is determined based on the reception strength of the unlock signal. The distance L0 between them is calculated. Since the distance between the owner and the vehicle has a unique correspondence with the reception strength of the unlock signal, it can be determined by setting the correspondence in advance.

Then, in the next step SF4, it is determined whether or not a set time ΔT (time shorter than the time until the owner reaches the vehicle) has elapsed. If this determination is NO, the process proceeds to step SF4. While the operation of SF4 is repeated, when the set time ΔT has elapsed and the determination is YES, the process proceeds to Step SF5, where the distance L1 between the owner and the vehicle is calculated from the reception strength of the unlock signal, and the next In step SF6,
It is determined whether the value of L0-L1 is smaller than 0. That is, it is determined whether or not the distance L1 between the owner and the vehicle after the lapse of the set time ΔT is greater than the distance L0 before the lapse of the set time ΔT.

If the determination in step SF6 is YES, the process proceeds to step SF7 to turn off both door mirror lamps 22 and returns. On the other hand, if the determination is NO, the process proceeds to step SF8 to change the value of L0 to L1.
, And in the next step SF9, it is determined whether or not the ignition switch 18 is ON. This step SF
If the determination in No. 9 is NO, the process returns to step SF4, while if the determination is YES, the process proceeds to step SF7 and thereafter returns.

When the owner of the vehicle approaches the vehicle to the reference distance by the signal processing operation of the CPU 16 of the on-vehicle device 15, the door lock is unlocked and the both side mirror lamps 22 are turned on. Then, as the owner further approaches the vehicle, the lighting state of both door mirror lamps 22 is maintained. When the owner gets into the vehicle and turns on the ignition switch 18, the both door mirror lamps 22 are turned off. On the other hand, when the owner moves away from the vehicle during the approach, the ignition switch 18 is turned on.
The two side mirror lamps 22 are extinguished even if they do not.

Therefore, according to the sixth embodiment, when an unlock signal having a reception intensity higher than the set value is received and it is detected that the owner of the vehicle is moving away from the vehicle, the double door mirror lamp 22 is turned off. Since the lighting is prohibited, the battery consumption can be suppressed as much as possible while improving the convenience for the owner of the vehicle.

(Embodiment 7) FIG. 10 shows Embodiment 7 of the present invention, in which raindrops are detected as environment detecting means for detecting that the owner of the vehicle is in an environment where it is difficult to grasp the surroundings of the vehicle. A raindrop sensor 30 is provided. still,
In the seventh embodiment, the hardware configuration includes the raindrop sensor 3
This is the same as Embodiment 6 except that 0 is provided.

That is, in the seventh embodiment, when the raindrop is detected by the raindrop sensor 30, it is determined that the owner of the vehicle is in an environment where it is difficult to grasp the surroundings of the vehicle. When raindrops are not detected by the sensor 30, it is assumed that it is not detected that the owner of the vehicle is in an environment where it is difficult to grasp the surroundings of the vehicle. Then, when the reception strength of the unlock signal received by the receiver 26 is greater than the set value, the on-vehicle device 15 performs an action related to the approach or separation of the owner of the vehicle with respect to the vehicle (specifically, this embodiment). In the seventh embodiment, the lighting of the door mirror lamp 22 is controlled in accordance with the approach speed of the vehicle owner to the vehicle (the same applies to the later-described eighth embodiment). When the approach speed of the vehicle owner is higher than a predetermined value,
Basically, the door mirror lamp 22 is not turned on. However, even if the approach speed of the vehicle owner is higher than a predetermined value, when the raindrop sensor 30 detects that the vehicle owner is in an environment where it is difficult to grasp the surroundings of the vehicle, the door mirror lamp 22 is turned on.

The signal processing operation performed by the CPU 16 of the vehicle-mounted device 15 will be described below in detail with reference to FIG.

First, in the first step SG1, it is determined whether or not an unlocking signal having a reception strength greater than the set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. Sometimes step SG

It is determined whether or not the raindrop is detected by the raindrop sensor 30.

If the determination in step SG3 is NO and a raindrop is detected, the flow proceeds to step SG8. If the determination is YES and no raindrop is detected, the flow proceeds to step SG4 and the unlock signal is output. , The distance L0 between the owner and the vehicle is calculated from the reception strength of the vehicle, and in the next step SG5, is the set time ΔT (time shorter than the time until the owner reaches the vehicle) elapsed? Determine whether or not. When the determination in step SG5 is NO, the operation in step SG5 is repeated, and when the set time ΔT elapses and the determination becomes YES, step SG6 is performed.
Then, the distance L1 between the owner and the vehicle is calculated from the reception strength of the unlock signal. Then, the next step SG7
And the approach speed of the owner to the vehicle (L0−L1) / Δ
It is determined whether T is greater than a predetermined value (for example, normal walking speed: 4 km / h). If the determination is YES, the process returns as it is. If the determination is NO, the process proceeds to step SG8.

In step SG8, both door mirror lamps 22 are turned on, and in next step SG9, it is determined whether or not the ignition switch 18 is ON. When this determination is NO, the operation of step SG9 is repeated, while when the determination is YES, step SG10
And turns off both door mirror lamps 22 and returns.

When the owner of the vehicle approaches the vehicle to the reference distance by the signal processing operation of the CPU 16 of the in-vehicle device 15, first, the door lock is unlocked. At this time, if no raindrop is detected by the raindrop sensor 30, that is, if it is not detected that the owner of the vehicle is in an environment where it is difficult to grasp the surroundings of the vehicle, the approach speed of the owner is calculated. When the approach speed is higher than a predetermined value, the both-side mirror lamp 22 remains off. On the other hand, if the approach speed is equal to or less than a predetermined value,
When both door mirror lamps 22 are turned on and the owner gets into the vehicle and turns on the ignition switch 18, both door mirror lamps 22 are turned off. Further, even if the approach speed of the vehicle owner is higher than a predetermined value, the raindrop sensor 30

Therefore, in the seventh embodiment, when the approach speed of the owner of the vehicle is higher than a predetermined value, the door mirror lamp 22 is basically not turned on, so that the consumption of the battery is effectively suppressed. Can be.
That is, when the approach speed of the owner of the vehicle is higher than a predetermined value, it can be determined that the owner is aware of the surroundings of the vehicle, such as running, so that the door mirror lamp 22 is not turned on. There is no problem. On the other hand, when the owner approaches slowly, it can be determined that the user walks while carefully watching the feet, etc., and in such a case, turning on the door mirror lamp 22 provides convenience for the owner. Can be enhanced. Then, even when the owner is running, etc., when the owner is in an environment where it is difficult to grasp the surroundings of the vehicle, such as during rainfall, the door mirror lamp 22 is turned on. Appropriate control can be performed to further enhance the convenience of the owner.

In the seventh embodiment, the raindrop sensor 30 is used as the environment detecting means for detecting that the owner of the vehicle is in an environment where it is difficult to grasp the surroundings of the vehicle. Alternatively, a device that detects the occurrence of fog or a device that detects the illuminance around the vehicle may be used.

(Eighth Embodiment) FIG. 12 shows an eighth embodiment of the present invention, in which the time until the owner of the vehicle arrives at the vehicle is calculated from the approach speed of the owner of the vehicle, and based on the calculated time. Thus, the lighting of the door mirror lamp 22 is controlled. In the eighth embodiment, the hardware configuration is the same as in the sixth embodiment.

That is, in the first step SH1, it is determined whether or not an unlocking signal whose reception strength is greater than the set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. Sometimes, the process proceeds to step SH2, in which the door lock actuator 23 is unlocked to unlock the door, and the next step SH3

In the next step SH4, the set time ΔT
(Less than the time it takes for the owner to reach the vehicle)
Is determined, if this determination is NO, the operation of step SH4 is repeated, and if the determination is YES after the set time ΔT has elapsed, the operation proceeds to step SH.
Proceeding to 5, the distance L1 between the owner and the vehicle is calculated from the reception strength of the unlock signal, and in the next step SH6, the approach speed V of the owner to the vehicle is calculated as V = (L0-L1). /
It is calculated by ΔT.

Next, in the next step SH7, the arrival time T to the owner's vehicle is calculated from the approach speed V and the distance L1 between the owner and the vehicle, and in the next step SH8,
It is determined whether T-T0 has elapsed. The value of T0 is a preset time (for example, 3 seconds), and is a time for turning on the door mirror lamp 22 before the time T0 for the owner to reach the vehicle.

When the determination in step SH8 is NO, the operation in step SH8 is repeated, while when the determination is YES, the process proceeds to step SH9, in which both door mirror lamps 22 are turned on. Then, the next step S
In step H10, it is determined whether the ignition switch 18 is ON. If the determination in step SH10 is NO, the operation in step SH10 is repeated. And returns.

When the owner of the vehicle approaches the vehicle by the signal processing operation of the CPU 16 of the on-vehicle device 15, the door lock is unlocked first, and then the approach speed V of the owner is reduced. The arrival time T to the owner's vehicle is calculated from the approach speed V, and the door mirror lamps 22 are turned on T0 before the arrival time T. Then, when the owner gets into the vehicle and turns on the ignition switch 18, both door mirror lamps 22 are turned off.

Also in the eighth embodiment, the receiver 26 and the CPU 16 of the in-vehicle device 15 are provided with action detecting means for detecting the action of the owner of the vehicle in approaching or leaving the vehicle, and the action of the owner of the vehicle with respect to the vehicle. And an approach speed detecting means for detecting the approach speed.

Therefore, in the eighth embodiment, the arrival time T from the owner of the vehicle to the vehicle is calculated from the approach speed V of the owner.
Is calculated and the lighting of the door mirror lamp 22 is controlled based on the arrival time T.
The door mirror lamp 22 can be turned on 0 hours before, and immediately after receiving the unlock signal, the door mirror lamp 22 can be turned on.
Need not be turned on. Therefore, battery consumption can be effectively suppressed while enhancing the convenience for the owner.

(Embodiment 9) FIG. 13 shows Embodiment 9 of the present invention, in which, in addition to the door mirror lamp 22, two bumper lamps 31 as illumination means for illuminating the periphery of the vehicle are further provided. The hardware configuration of the ninth embodiment is the same as that of the sixth embodiment except that the bumper lamp 31 is provided.

The two bumper lamps 31 are provided below the front and rear bumpers of the vehicle, respectively, so that the front and rear sides of the vehicle are illuminated by lighting. A total of four lamps are provided on the vehicle. Will be. Then, when the reception strength of the unlock signal received by the receiver 26 is greater than the set value, the on-vehicle device 15 performs an action related to the approach or separation of the vehicle owner (specifically, this implementation). In the ninth embodiment, the lighting of the door mirror lamp 22 and the bumper lamp 31 is controlled according to the distance between the owner of the vehicle and the vehicle (the same applies to a later-described embodiment 10). Specifically, the number of lamps to be turned on is changed.

The signal processing operation performed by the CPU 16 of the on-vehicle device 15 will be described below in detail with reference to FIG.

First, in the first step SI1, it is determined whether or not an unlocking signal having a reception strength greater than the set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. Sometimes step SI
Proceeding to 2, the door lock actuator 23 is unlocked to unlock the door, and in the next step SI3,
Both door mirror lamps 22 and both bumper lamps 31 are turned on.

Subsequently, in the next step SI4, the distance L between the owner and the vehicle is calculated from the reception strength of the unlock signal, and in the next step SI5, the distance L is set to the set distance L2.
It is determined whether it is smaller than. This set distance L2 is
The distance is set to be smaller than the reference distance at which the door lock is unlocked when the owner approaches the vehicle, and the owner hardly needs illumination by both bumper lamps 31.

When the determination in step SI5 is NO, the process proceeds to step SI6, in which the door mirror lamp 22 and the bumper lamp 31 are turned on for a predetermined time t3.
(Time during which battery consumption due to turning on the door mirror lamp does not matter) is determined.
If the determination in step SI6 is NO, the process returns to step SI4, while if the determination is YES, the process proceeds to step SI9.

On the other hand, the determination in step SI5 is YES
If so, the process proceeds to step SI7, where both bumper lamps 31 are turned off, and in the next step SI8, it is determined whether or not the ignition switch 18 is ON. When the determination in step SI8 is NO, the operation in step SI8 is repeated, and when the determination is YES, the process proceeds to step SI9.

In step SI9, both door mirror lamps 22 are turned off, and the process returns.

When the owner of the vehicle approaches the reference distance to the vehicle by the signal processing operation of the CPU 16 of the on-vehicle device 15, first, the door lock is unlocked, and both the door mirror lamp 22 and the both bumper lamps are released. 31
Is turned on, and thereafter, when the distance L between the owner and the vehicle becomes smaller than the set distance L2, both the bumper lamps 31 are turned off, and only the both door mirror lamps 22 continue to be turned on. Then, when the owner gets into the vehicle and turns on the ignition switch, both door mirror lamps 22 are turned off.

In the ninth embodiment, the receiver 26 and the CPU 16 of the on-vehicle device 15 constitute action detecting means for detecting the action of the owner of the vehicle in relation to approaching or leaving the vehicle. And a distance detecting means for detecting a distance between the vehicle and the vehicle.

Therefore, in the ninth embodiment, when the owner of the vehicle is at a position relatively distant from the vehicle, both door mirror lamps 22 and both bumper lamps 31 are turned on, so that the owner can recognize the presence of the vehicle. While it is easy to grasp the position and the situation of the entire surroundings of the vehicle, when the owner is very close to the vehicle, only the two door mirror lamps 22 for illuminating the left and right sides of the vehicle, which are considered to be required to be lit, are turned on. It is possible to prevent useless illumination by light. Therefore, while increasing the convenience of the owner,
Battery consumption can be effectively suppressed.

(Embodiment 10) FIG. 15 shows Embodiment 10 of the present invention, in which a reflector driving actuator 32 for driving the reflector of the door mirror lamp 22 to change the irradiation range of the door mirror lamp 22 is provided.
The tenth embodiment is the same as the sixth embodiment except that the irradiation range of the double-sided mirror lamp 22 can be changed.

When the unlock signal is received by the receiver 26, the vehicle-mounted device 15 changes the irradiation range of the door mirror lamp 22 according to the distance between the vehicle owner and the vehicle. (Note that, in the tenth embodiment, the irradiation range is not continuously changed, but the second range is smaller than the first range in both the vehicle longitudinal direction and the vehicle width direction than the first range.) Range and two steps).

The operation of signal processing performed by the CPU 16 of the vehicle-mounted device 15 will be described below in detail with reference to FIG.

First, in the first step SJ1, it is determined whether or not an unlocking signal having a reception strength greater than the set value has been received. If this determination is NO, the process returns as it is, while the determination is YES. Sometimes step SJ
Proceeding to 2, the door lock actuator 23 is unlocked to unlock the door, and in the next step SJ3,
The two door mirror lamps 22 are turned on with the irradiation range set to the first range.

Subsequently, in the next step SJ4, the distance L between the owner and the vehicle is calculated from the reception strength of the unlock signal, and in the next step SJ5, the distance L is set to the set distance L3.
It is determined whether it is smaller than. This set distance L3 is
The distance is set to be smaller than the reference distance at which the door lock is unlocked when the owner approaches the vehicle.

When the determination in step SJ5 is NO, the process proceeds to step SJ6, where the door mirror lamp 2
It is determined whether or not a predetermined time t4 (time during which the consumption of the battery due to the lighting of the door mirror lamp 22 does not cause a problem) has elapsed since the lighting of No. 2, and if the determination in step SJ6 is NO, the above-described step SJ4 On the other hand, when the determination is YES, the process proceeds to step SJ7. On the other hand, if the determination in step SJ5 is YES, the process directly proceeds to step SJ7.

In step SJ7, the irradiation range of both door mirror lamps 22 is reduced to the second range by the reflector driving actuator 32, and the next step SJ8 is performed.
It is determined whether the ignition switch 18 is ON. If the determination in step SJ8 is NO, the process proceeds to step SJ9 to determine whether a predetermined time t4 has elapsed since the turning on of the door mirror lamp 22. If the determination in step SJ9 is NO, the process proceeds to step SJ8. On the other hand, when the determination is YES,
Proceeding to step SJ10, both door mirror lamps 22 are turned off and the routine returns. On the other hand, when the determination in the step SJ8 is YES, the step SJ8
Go to J10 and return after a while.

When the owner of the vehicle approaches the reference distance to the vehicle by the signal processing operation of the CPU 16 of the on-vehicle device 15, first, the door lock is unlocked and the both side mirror lamps 22 are turned on. At this time, the irradiation range of the door mirror lamp 22 is set to the first range (relatively wide range), and a considerably wide range is illuminated on both the left and right sides of the vehicle. Thereafter, if the distance L between the owner and the vehicle becomes smaller than the set distance L3 before a predetermined time t4 has elapsed since the turning on of the door mirror lamp 22, the irradiation range of the door mirror lamp 22 becomes the second range (relatively). (Narrow range), and only the vicinity of the driver's seat door and the vicinity of the passenger seat door on the left and right sides of the vehicle are illuminated. Then, when the owner gets into the vehicle and turns on the ignition switch, both door mirror lamps 22 are turned off. Further, even if the predetermined time t4 has elapsed since the door mirror lamp 22 was turned on,
The door mirror lamp 22 goes out.

In the tenth embodiment, the vehicle-mounted device 15
Of the receiver 26 and the CPU 16 constitute action detecting means for detecting the action of the owner of the vehicle toward or away from the vehicle, and distance detecting means for detecting the distance between the owner of the vehicle and the vehicle. are doing.

Therefore, in the tenth embodiment, when the owner of the vehicle is at a position relatively distant from the vehicle,
By making the irradiation range of the door mirror lamp 22 wider, it becomes easier for the owner to grasp the location of the vehicle and the situation around the vehicle. On the other hand, when the owner comes quite close to the vehicle, the irradiation range is made narrower. It is possible to mainly illuminate a portion where it is considered necessary to illuminate, and the same operation and effect as in the ninth embodiment can be obtained without increasing the number of door mirror lamps 22.

In the first to tenth embodiments, the portable device 1
Is configured to automatically transmit an identification signal (user authentication signal or unlock signal) to the in-vehicle device 15.
Means that the owner operates the switch so that the
5 may be one that transmits an identification signal or one that is separate from the one that unlocks the door. further,
Instead of automatically transmitting the identification signal from the portable device 1 to the on-vehicle device 15, the identification signal is transmitted from the on-vehicle device 15 to the portable device 1, and the portable device 1 responds to the identification signal. May be transmitted to the vehicle-mounted device 15. In this case, for example, in the first embodiment, a step of “transmitting a user authentication signal to the portable device 1” is provided before step SA1 of FIG. 2, and in step SA1, it is determined whether or not the user authentication signal is received. Instead of “Yes”, “Determine whether a response signal from the portable device 1 to the user authentication signal has been received” may be performed.
