  FIG. 5 is a flowchart showing a flow of control related to the marker lamp groups 63 and 64 among the control by the alerting device 200. First, the lamp control unit 210 determines whether or not the main switch of the engine is turned on in the first step S100, and when it is determined that it is turned on (YES), the process proceeds to the next step S102. In step S102, it is determined whether or not the turn lever 80 has been operated (ON). If it is determined that the turn lever 80 has been operated (YES), the process proceeds to the next step S104 to determine whether the operation is a right turn operation or a left turn operation. to decide.

  In the case of a left turn operation, the process proceeds to step S105, the left marker lamp group 63 is turned on, and the process proceeds to the next step S108. On the other hand, in the case of a right turn operation, the process proceeds to step S107, the right marker lamp group 64 is turned on, and the process proceeds to the next step S108. In step S108, it is determined whether or not the operated turn lever 80 has been turned off. When it is determined that the turn lever 80 has not been turned off (NO), the marker lamp groups 63 and 64 are continuously lit, but are turned off. When it is determined that (YES), the process proceeds to the next step S110.

  In step S110, the time since the turn lever 80 is turned off is measured, and it is determined whether or not the time has elapsed for a predetermined time, for example, 3 to 5 seconds, and when it is determined that the predetermined time has elapsed (YES). Shifts to the next Step S112. In step S112, the marker lamp groups 63 and 64 that have been turned on are turned off, and the process proceeds to the last step S114. In step S114, it is determined whether or not the main switch has been turned off. When it is determined that the main switch has been turned off (YES), the process ends, but when it is determined that the main switch has not been turned off (NO), Returning to step S102, the same processing is repeated.

  FIG. 6 and FIG. 7 show the behaviors of surrounding pedestrians and bicycles when the large vehicle 100 is turned left by such control. That is, when the driver of the large vehicle 100 makes a left turn at the intersection, the turn lever 80 is operated to turn on (blink) the left turn signal lamp 66 when it is several tens of meters before entering the intersection. Then, in conjunction with the operation of the turn lever 80, the left marker lamp group 64 is instantly turned on to illuminate the left side of the vehicle body at once.

  As a result, the left side of the vehicle body suddenly becomes brighter and becomes conspicuous even from a distance, so that it is possible to reliably inform the surrounding pedestrians, bicycles, motorcycles, etc. about the left turn of the large vehicle 100 in advance. In particular, even for large tow cars that do not understand the behavior when turning right and left compared to general large vehicles that are frequently seen such as large trucks and buses, it is suitable for surrounding pedestrians, bicycles, motorcycles, etc. Since it is possible to reliably call attention and stop unreasonable behavior, it is possible to prevent contact or entanglement accidents caused by surrounding pedestrians when turning left. Moreover, since it is not a voice alert, it does not cause noise around the intersection.

  Even when the turn lever 80 automatically returns by turning the steering wheel during the left turn operation and the left turn signal lamp 66 is once turned off, the left marker lamp group 64 continues to be lit for several seconds thereafter. Thereby, even if the operation of the turn lever 80 stops without permission, the left marker lamp group 64 continues to be lit for a predetermined time without being turned off, so that it is possible to continue to draw attention to surrounding pedestrians and the like. After that, after a few seconds have elapsed since the left turn is completed, the left marker lamp group 64 is automatically turned off, so that power (battery) is not wasted.

  On the other hand, when driving on the right turn, the right marker lamp group 63 is lit in conjunction with the operation of the turn lever 80, and the right side of the vehicle body is illuminated brightly at a stroke to call attention. This action can be stopped for pedestrians and bicycles. As a result, it is possible to prevent contact or entrainment accidents caused by surrounding pedestrians and the like when traveling right. In the present embodiment, the marker lamp group 63 or 64 continues to be lit while the turn lever 80 is operating. However, the marker lamp group 63 or 64 is flashed in conjunction with the flashing of the signal lamps 65 and 66 or in a unique cycle. Anyway.

  Further, if only the marker lamp groups 63 and 64 in the turning direction are turned on as in the above-described embodiment, the marker lamp lighting power (battery) is prevented while preventing unnecessary lighting of the marker lamps that do not contribute much to the avoidance of accidents. ), Etc., as shown in step S108 of FIG. 8, when the turn lever 80 is operated regardless of the left or right turn direction of the vehicle, all the marker lamp groups 63 and 64 are operated. May be lit. Further, as shown in step S111 in the figure, all the marker lamp groups 63 and 64 may be turned off simultaneously with the return of the turn lever 80.

  In the present embodiment, the lamp control unit 210 electronically controls the lighting of the marker lamp groups 63 and 64. However, the marker control unit 210 uses an analog circuit such as a bimetal or an electronic relay linked with a turn signal relay. The lighting of the lamp groups 63 and 64 may be controlled.

  Further, as shown in FIG. 9, the marker lamp groups 63 and 64 may be lit in conjunction with the back lamp 68. That is, if the main switch is turned on in the first step S100, whether or not the back gear switch (SW) 44 is turned on in the next step S103, that is, the shift lever is put in the back gear (reverse). It is determined whether or not the vehicle has run backward. When it is determined that the back gear SW 44 is turned on (YES), the process proceeds to the next step S106, the marker lamp groups 63 and 64 are all lit, and the process proceeds to the next step S109. In step S109, it is determined whether or not the back gear SW44 is turned off, that is, whether or not the shift lever is disengaged from the back gear. If it is determined that the back gear SW44 is turned off, the process proceeds to the next step S110. .

  In step S110, the time since the back gear SW 44 is turned off is measured, and it is determined whether or not the time has elapsed for a predetermined time, for example, 3 to 5 seconds, and when it is determined that the predetermined time has elapsed (YES). Shifts to the next Step S111. In step S111, all the marker lamp groups 63 and 64 that have been turned on are turned off, and the process proceeds to the last step S114. In step S114, it is determined whether or not the main switch has been turned off. When it is determined that the main switch has been turned off (YES), the process ends, but when it is determined that the main switch has not been turned off (NO), Returning to step S102, the same processing is repeated.

  In this way, if the back gear SW 44 is turned on and the marker lamp groups 63 and 64 are interlocked with the lighting of the bup lamp 68, the large vehicle can be reliably moved backwards by pedestrians around it. I can let you know. As a result, attention can be drawn to surrounding pedestrians, bicycles, motorcycles, and the like, so that contact or entanglement accidents caused by surrounding pedestrians when the vehicle body is retracted can be prevented.

  In the flow of FIG. 9, all the marker lamp groups 63 and 64 are turned off after the back gear SW 44 is turned off and a predetermined time elapses. However, all the marker lamps are turned off simultaneously when the back gear SW 44 is turned off. The groups 63 and 64 may be turned off. Further, when the marker lamp groups 63 and 64 are lit, the blinking may be repeated at a predetermined interval.
