More specifically, as shown in FIG. 5, when the start command signal SLstart is received, the meter ECU 60 starts the left side lighting process simultaneously with the reception of the start command signal SLstart (time t53).

  In the left side lighting process, first, the outer side lighting portion 24a of the left side lighting unit 24 is turned on, and when the divided lighting time Tbk elapses from the lighting start, the center lighting portion 24b is kept while the lighting of the outer side lighting portion 24a is continued. Further, when the divided lighting time Tbk has elapsed from the lighting start while the lighting of the outer lighting portion 24a and the central lighting portion 24b continues, the inner lighting portion 24c is lit, and the divided lighting time Tbk from the lighting start Is a process of turning off "all the lighting portions 24a to 24c".

(Stop of left side lighting control L0)
When the left rear vehicle 10c is not detected, the radar sensor ECU 42 transmits, to the driving support ECU 50, a left rear vehicle non-detection signal SLhkc for notifying the driving support ECU 50 that the left rear vehicle 10c is not detected. When the driving support ECU 50 receives the left rear vehicle non-detection signal SLhkc, the driving support ECU 50 transmits, to the meter ECU 60, a stop command signal SLstop for stopping the left side lighting control L0.

  When the meter ECU 60 receives the stop command signal SLstop at a time point during the predetermined interval Titv in the left side lighting control L0, the meter ECU 60 stops the left side lighting control L0 simultaneously with the reception of the stop command signal SLstop.

  On the other hand, when the meter ECU 60 receives the stop command signal SLstop at the time when the left side lighting process is being performed, the meter ECU 60 completes the left side lighting process being performed and simultaneously stops the left side lighting control L0.

  The above is the outline of the left side lighting control L0 by the present embodiment. According to this, the driver of the host vehicle 10a can know that the left rear vehicle 10c is present to the left rear of the host vehicle 10a by lighting of the left side lighting unit 24.

<When the rear right vehicle is detected after the detection of the rear left vehicle>
By the way, the left rear vehicle 10c is detected as shown in (A) of FIG. 8 and then the left rear vehicle 10c is detected as shown in (B) of FIG. The right rear vehicle 10b may be detected in a state where it is being executed. In this case, the meter ECU 60 controls the lighting of the right lighting unit 23 according to the detection timing of the right rear vehicle 10b as described below.

(Right-hand lighting control R1)
As shown in FIG. 9, when the right rear vehicle 10b is detected at time t90 during the predetermined interval Titv during execution of the left lighting control, the meter ECU 60 performs right lighting described below at the time of detection of the right rear vehicle 10b. Start control R1. That is, the meter ECU 60 starts “control for repeatedly performing the right side lighting process at predetermined intervals Titv” simultaneously with the start of the left side lighting process (time t91) performed immediately after the detection of the right rear vehicle 10b.

(Right side control R2)
Furthermore, as shown in FIG. 10, when the right rear vehicle 10b is detected at time t100 during execution of the left side lighting process, the meter ECU performs right lighting control R2 described below at the detection time of the right rear vehicle 10b. Start. That is, after completion of the left side lighting process under execution, the meter ECU 60 starts “control to repeat the right side lighting process with the predetermined interval Titv repeated” at time t101 when the predetermined interval Titv passes.

  The above is the outline of the operation of the present implementation device when the right rear vehicle 10b is detected after the detection of the left rear vehicle 10c. According to the right side lighting control R1, even when the right side lighting unit 23 starts lighting when the right rear vehicle 10b is detected during the left side lighting process, the lighting start of the right side lighting unit 23 by the right side lighting process is started And turn off (end of lighting) aligns with the start of lighting and turning off (end of lighting) of the left side lighting unit 24, respectively. Therefore, it is possible to reduce the possibility that the driver may feel bothered in lighting the right side lighting unit 23 and the left side lighting unit 24, or the driver may overlook that the right rear vehicle 10b is detected.

<Case where a left rear vehicle is detected after detection of a right rear vehicle>
(Left side lighting control L1 and L2)
By the way, the right rear vehicle 10b may be detected, and then the left rear vehicle 10c may be detected in a state in which the right rear vehicle 10b is detected (that is, a state in which the right lighting control is performed). In this case, the meter ECU 60 executes one of the “left lighting controls L1 and L2” similar to the “right lighting controls R1 and R2” according to the detection timing of the left rear vehicle 10c. Control lighting.

  According to the left side lighting control L1, even when lighting of the left side lighting unit 24 is started when the left rear vehicle 10c is detected during execution of the right side lighting process, lighting start of the left side lighting unit 24 by the left side lighting process and The light off (lighting end) is aligned with the lighting start and light off (lighting end) of the right side lighting unit 23, respectively. Therefore, it is possible to reduce the possibility that the driver may feel bother in lighting of the right side lighting unit 23 and the left side lighting unit 24 or may overlook the detection of the left rear vehicle 10c.

<Specific operation of this implementation device>
Next, the specific operation of the present embodiment will be described. The CPU (hereinafter simply referred to as “CPU”) of the driving support ECU 50 of the present embodiment executes the routine shown by the flowchart in FIG. 11 each time a predetermined time elapses. Therefore, at the predetermined timing, the CPU starts the process from step 100 in FIG. 11 and proceeds to step 105 to determine whether the right rear vehicle 10b is detected.

  When the right rear vehicle 10b is detected, the CPU makes a “Yes” determination in step 105, proceeds to step 110, and determines whether the value of the right side lighting flag Xr is “0”.

  The value of the right side lighting flag Xr is a step executed after the start command signal SRstart for starting the right side lighting control is sent to the meter ECU 60 by the processing of any of “step 120, step 135 and step 140 described later”. It is set to "1" by the processing of 125. Therefore, when the value of the right side lighting flag Xr is “1”, the right side lighting flag Xr indicates that the right side lighting control is being executed.

  On the other hand, the value of the right side lighting flag Xr is set to "0" by the process of step 155 executed after the stop command signal SRstop for stopping the right side lighting control is sent to the meter ECU 60 by the process of step 150 described later. Be done. Therefore, when the value of the right side lighting flag Xr is “0”, the right side lighting flag Xr indicates that the right side lighting control is being stopped.

  If the value of the right side lighting flag Xr is "0" when the CPU executes the process of step 110, the CPU determines "Yes" in step 110 and proceeds to step 115, and the value of the left side lighting flag Xl is It is determined whether it is "0".

  The value of the left side lighting flag Xl is set to "1" when the start command signal SLstart for starting the left side lighting control is sent to the meter ECU 60. Therefore, when the value of the left side lighting flag X1 is "1", the left side lighting flag X1 indicates that the left side lighting control is being executed.

  On the other hand, when the stop command signal SLstop for stopping the left side lighting control is sent to the meter ECU 60, the value of the left side lighting flag Xl is set to "0". Therefore, when the value of the left side lighting flag X1 is “0”, the left side lighting flag X1 indicates that the left side lighting control is being stopped.

  If the value of the left lighting flag Xl is "0" when the CPU executes the process of step 115, the CPU determines that the result of step 115 is "Yes", and performs the process of steps 120 and 125 described below. Then, the process proceeds to step 195 to end this routine once.

  Step 120: The CPU sends to the meter ECU 60 a start command signal SRstart for starting the right side lighting control R0. Thereby, meter ECU60 starts said right side lighting control R0.

  Step 125: The CPU sets the value of the right side lighting flag Xr to "1".

  On the other hand, if the value of the left side lighting flag Xl is "1" at the time when the CPU executes the process of step 115, the CPU determines "No" in step 115 and proceeds to step 130 and turns on the left side. It is determined whether the process is being executed. When the left side lighting process is being executed, the CPU makes a “Yes” determination at step 130, proceeds to step 135, and sends out to the meter ECU 60 a start command signal SRstart for starting the right side lighting control R2. Thereby, meter ECU60 starts right side lighting control R2.

  Thereafter, the CPU proceeds to step 125 and sets the value of the right side lighting flag Xr to “1”, and then proceeds to step 195 and temporarily ends this routine.

  On the other hand, when the left side lighting process is not being executed at the time when the CPU executes the process of step 130, the CPU determines “No” in step 130 and proceeds to step 140 to perform the right side lighting control R1. A start command signal SRstart for starting is sent to the meter ECU 60. Thereby, meter ECU60 starts right side lighting control R1.

  Thereafter, the CPU proceeds to step 125 and sets the value of the right side lighting flag Xr to “1”, and then proceeds to step 195 and temporarily ends this routine.

  After the CPU sends the start command signal SRstart for starting the right side lighting control to the meter ECU 60 as described above, the value of the right side lighting flag Xr is set to “1”. Therefore, while the right rear vehicle 10b is once detected and thereafter the right rear vehicle 10b is still detected, the CPU determines "Yes" in step 105, proceeds to step 110, and proceeds to step 110. The determination is “No”, the process directly proceeds to step 195, and this routine is temporarily ended.

  Furthermore, when the right rear vehicle 10b is not detected at the time when the CPU executes the processing of step 105, the CPU determines “No” in step 105 and proceeds to step 145, and the value of the right lighting flag Xr is It is determined whether or not it is "1". That is, it is determined whether the right side lighting control is currently being executed. If the value of the right side lighting flag Xr is "1", the CPU determines "Yes" in step 145, sequentially performs the processing of step 150 and step 155 described below, and then proceeds to step 195 to execute this process. End the routine once.

  Step 150: The CPU sends to the meter ECU 60 a stop command signal SRstop for stopping the right side lighting control being executed. Thereby, the right side lighting control is stopped.

  Step 155: The CPU sets the value of the right side lighting flag Xr to "0".

  On the other hand, if the value of the right side lighting flag Xr is “0” at the time when the CPU executes the processing of step 145, the CPU determines “No” in step 145 and proceeds directly to step 195. End the routine once.

  The above is the specific operation of the present embodiment for controlling the lighting of the right side lighting unit 23. According to this, when the right rear vehicle 10b is detected during execution of the left side lighting process (determination with "Yes" in each of Step 105 and Step 110, determination with "No" in Step 115, and The lighting of the right side lighting unit 23 is started at the detection time of the right rear vehicle 10b (i.e., in the middle of the left side lighting process) (step 135). However, in this case, the lighting start and extinguishing (lighting end) of the right side lighting unit 23 by the subsequent right side lighting processing are aligned with the lighting start and extinguishment (lighting end) of the left side lighting unit 24 (step 135). Therefore, it is possible to reduce the possibility that the driver may feel bothered in lighting the right side lighting unit 23 and the left side lighting unit 24, or the driver may overlook that the right rear vehicle 10b is detected.

  Although not shown, the CPU executes control of lighting of the left side lighting unit 24 when the left rear vehicle 10c is detected by a routine similar to the routine shown in FIG.
