  By the way, when analyzing accidents involving vehicles such as trucks and buses, it can be seen that there are many accidents that contact pedestrians at intersections. Many of the causes of the accident are due to the driver overlooking a pedestrian or bicycle that moves to the side of the vehicle when turning left and right at night (especially when turning right).

  When a pedestrian or bicycle is moving on the side of the vehicle, the driver can visually recognize the pedestrian or bicycle through the side mirror. However, since pedestrians and bicycles do not illuminate lights or have low illumination intensity of lights, it is difficult to visually recognize pedestrians and bicycles moving on the side of the vehicle at night. In particular, medium- and large-sized vehicles such as trucks and buses have a longer overall length than passenger cars and are not equipped with lights that illuminate the side of the vehicle. It becomes even more difficult.

The left / right folding operation detection device 11 includes a sensor that detects a left / right folding operation of the winker lever. The left and right turn operation detection device 11 may detect both left turn operation and right turn operation, but since there are more contact accidents at the time of a right turn than a contact accident at the time of a left turn, one of the operations is detected. In this case, it is preferable to detect a right turn operation. And the left-right folding operation detection apparatus 11 will transmit the detection information to ECU15, if the left-right folding operation by a driver is detected.

  The moving body detection device 12 is a device that detects a moving body such as a pedestrian or a bicycle that moves on the side of the vehicle. The moving body detection device 12 is configured by a UWB (Ultra-Wide Band) radar, a laser radar, or the like. As shown in FIG. 2, the moving body detection device 12 is mounted on a side portion of the vehicle and can detect a moving body such as a pedestrian or a bicycle that moves on the side of the vehicle. The moving body detected by the moving body detection device 12 may move in any direction. However, from the viewpoint of preventing a contact accident at the time of turning left and right, the moving body moves in the same direction as the traveling direction of the host vehicle. It is preferable that it is a body. The detection range in which the moving body detection device 12 detects the moving body is not particularly limited. However, from the viewpoint of detecting the moving body with high accuracy and preventing a contact accident at the time of a left or right turn, The range is preferably within 30 m. And the mobile body detection apparatus 12 will transmit the detection information to ECU15, if the mobile body which moves the side of a vehicle is detected.

  The vehicle width lamp 13 is an illuminating device attached to a side portion of the vehicle, and is an illuminating device that can be visually recognized by a driver through a door mirror. The vehicle width lamp 13 may be a vehicle width lamp that is required to be attached to the vehicle by law.

  The spotlight 14 is an illumination device that illuminates the side of the vehicle. The spotlight 14 is an illuminating device that is attached to a side portion of the vehicle and irradiates light with a higher illuminance than the vehicle width lamp 13 in a narrow range. The mounting position of the spotlight 14 is not particularly limited, but is preferably a position where the driver can visually recognize it through the door mirror. In addition, the irradiation direction of the spotlight 14 is not particularly limited. However, when the vehicle turns right or left, the irradiation direction is applied to a moving object such as a pedestrian or a bicycle crossing a pedestrian crossing through which the vehicle passes. Preferably there is. The spotlight 14 may be fixedly attached to the vehicle or may be attached movably.

  The ECU 15 is an electronic control unit that includes a CPU, a ROM, a RAM, and the like and performs various controls of the host vehicle. The ECU 15 includes a lighting control unit 16 that performs lighting control of the vehicle width lamp 13 and the spotlight 14 based on detection information transmitted from the left / right folding operation detection device 11 and the moving body detection device 12.

  FIG. 3 is a diagram illustrating a state when the vehicle turns right. As shown in FIG. 3, the lighting control unit 16 detects the moving body moving on the side of the vehicle by the moving body detection device 12 and the left and right folding operation detection device 11 detects the left and right folding operation by the driver. The width lamp 13 and the spotlight 14 are turned on. As a lighting mode, various modes such as a mode in which the lighting state is continued for a predetermined time and a flashing mode in which lighting and extinguishing are repeated at a predetermined cycle can be employed.

  At this time, the lighting control unit 16 does not need to turn on both the vehicle width lamp 13 and the spotlight 14, and may turn on only the vehicle width lamp 13 or only the spotlight 14.

  Further, when the left / right turn operation detecting device 11 detects a right turn operation by the driver, the lighting control unit 16 does not turn on the width lamp 13 and the spotlight 14 attached to the left side portion of the vehicle, and turns on the right side of the vehicle. Only the vehicle width lamp 13 and the spotlight 14 attached to the part may be turned on. Similarly, when the left / right turn operation detection device 11 detects a left turn operation by the driver, the lighting control unit 16 does not turn on the vehicle width lamp 13 and the spotlight 14 attached to the right side of the vehicle, and Only the vehicle width lamp 13 and the spotlight 14 attached to the left side may be turned on. FIG. 3 shows a case where only the vehicle width lamp 13 and the spotlight 14 attached to the right side of the vehicle are turned on at the time of a right turn.

  As described above, according to the alert system 1 according to the present embodiment, when the moving body detection device 12 detects a moving body that moves on the side of the vehicle, the lighting control unit 16 includes at least the vehicle width lamp 13 and the spotlight 14. Since one of the lights is turned on, the moving body moving on the side of the vehicle at night is guided to the driver so that the moving body can be noticed.

  At this time, lighting the vehicle width lamp 13 can prompt the driver to guide the line of sight at a low cost. On the other hand, by turning on the spotlight 14, it is possible to prompt the driver to guide the line of sight and to improve the visibility of the moving object. In addition, by performing lighting control of both the vehicle width lamp 13 and the spotlight 14, it is possible to further prompt the driver to guide the line of sight.

  In addition, since there are many contact accidents with the moving body at the left and right turn at night, the moving body detecting device 12 detects the moving body moving on the side of the vehicle, and the left and right turning operation detecting device 11 is operated by the driver. When the lighting control unit 16 detects lighting, the lighting control unit 16 performs lighting control of at least one of the vehicle width lamp 13 and the spotlight 14, so that unnecessary warning can be suppressed and efficient warning can be performed.

[Second Embodiment]
Next, a second embodiment will be described. The second embodiment is basically the same as the first embodiment. For this reason, in the following description, only matters different from the first embodiment will be described, and the same description as in the first embodiment will be omitted.

  FIG. 4 is a block diagram illustrating a schematic configuration of the alerting system according to the second embodiment. As shown in FIG. 4, the alert system 2 according to the present embodiment is a system mounted on a vehicle, and includes a moving body detection device 21, a left / right folding operation detection device 11, a vehicle width lamp 13, a spot A light 22 and an ECU 23 are provided.

  The mobile body detection device 21 is basically the same as the mobile body detection device 12 of the first embodiment, but can also detect the position of the mobile body that moves on the side of the vehicle. . Note that the moving body detection device 12 of the first embodiment may also detect the position of the moving body. The position of the moving body may be an absolute position or a relative position with respect to the host vehicle. And the mobile body detection apparatus 21 will transmit the detection information to ECU15, if the mobile body which moves the side of a vehicle, and the position of the said mobile body are detected.

  The spotlight 22 is basically the same as the spotlight 14 of the first embodiment, but further includes an irradiation direction changing device 24 that changes the irradiation direction.

  The irradiation direction changing device 24 may be any device as long as the irradiation direction of the spotlight 22 can be changed. For example, the irradiation direction changing device 24 may change the irradiation direction of the spotlight 22 by moving the direction of the light bulb or reflector of the spotlight 22, and rotates the spotlight 22 with respect to the vehicle. By doing so, the irradiation direction of the spotlight 22 may be changed.

  The ECU 23 is basically the same as the ECU 15 of the first embodiment, but includes a lighting control unit 16 and an irradiation direction change control unit 25 that performs drive control of the irradiation direction change device 24.

  The irradiation direction change control unit 25 irradiates the light of the spotlight 22 to the current position of the moving body by performing drive control of the irradiation direction changing device 24. More specifically, the irradiation direction change control unit 25 acquires the current position of the moving body based on the detection information transmitted from the moving body detection device 21. The irradiation direction change control unit 25 then applies the irradiation direction changing device 24 so that the light of the spotlight 22 is irradiated to the acquired current position of the moving body, that is, the light of the spotlight 22 follows the moving body. Is controlled. Thereby, the moving body continues to be irradiated with the light of the spotlight 22.

  By the way, the own vehicle and the moving body are moving objects. In addition, there is a time lag between when the moving body detection device 21 detects the position of the moving body and when the drive control of the irradiation direction change device 24 by the irradiation direction change control unit 25 is completed. For this reason, even if the irradiation direction of the spotlight 22 is changed, the moving body may have already moved outside the irradiation position of the spotlight 22.

  In such a case, a moving body movement path prediction unit (not shown) that predicts the movement path of the moving body detected by the moving body detection device 21 and a host vehicle movement path prediction unit (not shown) that predicts the movement path of the host vehicle. The irradiation direction change control unit 25 moves based on the moving path of the moving body predicted by the moving body moving path prediction unit and the moving path of the own vehicle predicted by the own vehicle moving path prediction unit. It is preferable to irradiate the current position of the body with the light of the spotlight 22.

  In addition, the movement path | route of a moving body can be calculated by various well-known methods. For example, based on the position of the moving object detected by the moving object detection device 21, the moving path so far of the moving object and the moving speed and moving direction when the moving object detection device 21 finally detected are calculated. The moving path of the moving body after a predetermined time can be calculated from the calculated moving path, moving speed and moving direction of the moving body. In addition, the travel route of the host vehicle can be calculated by various known methods. For example, the current travel route of the host vehicle and the current travel speed and travel direction are calculated from each sensor of the GPS and the host vehicle, and predetermined values are calculated from the calculated travel route, travel speed, and travel direction of the host vehicle. It can be obtained by calculating the travel route of the host vehicle after time. And the light of the spotlight 22 can be irradiated to the present position of a moving body by irradiating the light of the spotlight 22 in the relative direction of the moving body with respect to the own vehicle at the present time.

  Thus, according to the alerting system 2 according to the present embodiment, it is possible to alert the moving body by irradiating the current position of the moving body with the light of the spotlight 22 and to move the moving body. The visibility of the body can be further improved.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment.

  For example, in the above embodiment, the lighting device is turned on when the left / right folding operation detection device detects a left / right folding operation by the driver. The lighting device may be turned on when a moving body is detected.

  In the above embodiment, the lighting device is turned on when a moving body is detected on the side of the vehicle. However, in addition to lighting of the lighting device, a warning is displayed on the vehicle meter or an alarm is sounded. The driver may be alerted, or an alarm may be sounded from a sound output device such as a speaker to alert the moving object.
