Description

  The present invention relates to a vehicular rapid deceleration indicator lamp device (a vehicular rapid deceleration indicator lamp system) that notifies a driver of a following vehicle of a sudden deceleration state of a host vehicle by blinking a lamp.

  This kind of vehicular rapid deceleration indicator lamp device is conventionally known (for example, Patent Document 1). A conventional vehicle rapid deceleration indicator lamp device will be described below. A conventional vehicle rapid deceleration indicator lamp device includes a brake lamp, a vehicle speed sensor, a blinking speed calculation control circuit, and a brake lamp lighting circuit. In a conventional vehicle rapid deceleration indicator lamp device, the blinking speed calculation control circuit calculates the deceleration rate of the vehicle speed based on the output signal from the vehicle speed sensor, and when the deceleration rate exceeds the set value, the speed corresponding to the deceleration rate A lamp flashing signal for flashing the brake lamp is output to the brake lamp lighting circuit, and the brake lamp lighting circuit flashes the brake lamp at a flashing speed corresponding to the lamp flashing signal from the flashing speed calculation control circuit. As a result, the conventional vehicle rapid deceleration indicator lamp device can inform the driver of the following vehicle of the sudden deceleration state of the own vehicle to call attention (call attention) and contribute to traffic safety. . In addition, the conventional vehicle rapid deceleration indicator lamp device has an effect of notifying the driver of the following vehicle of the sudden deceleration state (rapid braking state) of the host vehicle in the initial stage of the flashing of the brake lamp, and the brake. In a stage after the initial stage of the blinking of the lamp, an indicator function indicating that the host vehicle is continuing the rapid deceleration state can be achieved.

  However, the conventional vehicle rapid deceleration indicator lamp device blinks the brake lamp at a speed corresponding to the deceleration rate of the vehicle, but the speed at which the brake lamp is turned on and the speed at which the brake lamp is turned off (that is, the brake lamp is blinked). The rising speed and falling speed) are constant. As a result, the conventional vehicle rapid deceleration indicator lamp device is useful for drivers of subsequent vehicles who are aware of the sudden deceleration state of the preceding vehicle and are closely watching the preceding vehicle when the brake lamp is instantaneously started and stopped. The flashing light of the brake lamp that lasts for several seconds is a strong stimulus, which may cause discomfort or stress to the driver of the following vehicle. In particular, when a semiconductor-type light source such as an LED that rises and falls instantaneously is used as a light source for a brake lamp, the above-mentioned possibility appears remarkably. On the other hand, in the case of a conventional vehicle rapid deceleration indicator lamp device, when the brake lamp rises and falls slowly, the strong stimulation of the flashing light of the brake lamp is alleviated. Is damaged.

In FIG. 2, 100 of the vehicle speed (km / h) indicates 100 km / h, and 0 of the vehicle speed (km / h) indicates 0 km / h, that is, the vehicle is stopped. Further, in FIG. 2, the lamp 1 and the lamp 2 are turned on, and the lamp 1 and the lamp 2 are turned off. Furthermore, in FIG. 2, T1 indicates an initial stage, and T2 indicates a subsequent stage. Furthermore, in FIG. 2, t1 indicates when the vehicle is suddenly decelerated, t2 indicates when the initial stage T1 has elapsed, that is, when the initial stage T1 switches to the transition stage T2, and t3 indicates when the vehicle is The time when the lamp is stopped, that is, when the blinking state of the lamp 1 and the lamp 2 is finished is shown.

  Hereinafter, the configuration of the vehicle rapid deceleration indicator lamp device according to the first embodiment will be described. As shown in FIG. 1, the vehicle rapid deceleration indicator lamp device according to the first embodiment includes a lamp 1, a deceleration detection unit 2, and a control device 3.

  The lamp 1 is disposed at a predetermined position of a vehicle (not shown). In this example, the lamp 1 uses a brake lamp provided at the rear of the vehicle. The brake lamp 1 is turned on when a brake pedal (not shown) is depressed and the brake switch 10 is turned on, and is turned off when the brake switch is released and the brake switch 10 is turned off. As the light source of the brake lamp 1, for example, a self-luminous semiconductor type light source (LED in this embodiment) such as LED and EL (organic EL) is used.

  The deceleration detection unit 2 detects a deceleration state of the vehicle and outputs a detection signal by operating a brake device (not shown), for example. In this example, the deceleration detection unit 2 uses a vehicle speed sensor. The vehicle speed sensor detects a vehicle speed (accelerated state or decelerated state) and outputs a detection signal thereof.

  As shown in FIG. 1, the control device 3 includes a storage unit 4, a determination unit 5, and a lamp driving unit 6. The control device 3 uses a computer mounted on a vehicle, for example, a car navigation (navigation system) computer, a control circuit unit, or a dedicated ECU (electronic control unit). The control device 3 sequentially processes the steps of the flowchart shown in FIG.

The storage unit 4 is, for example, a ROM, and includes a first parameter for determining a sudden deceleration state of the vehicle, a second parameter for determining the progress of the initial stage T1, and the brake lamp 1 A first flashing signal for flashing in a first flashing pattern in an initial stage T1, a second flashing signal for flashing the brake lamp 1 in a second flashing pattern in the subsequent stage T2, and a turn-off signal for turning off the brake lamp 1 , Is stored. In this example, the vehicle is in a sudden deceleration state is about 6 m / s ² or more.

  As shown in the initial stage T1 of “LAMP 1” in FIG. 2, the first blinking pattern is a blinking pattern that turns on and off (flashes) the brake lamp 1 instantaneously in the initial stage T1. Similarly, as shown in the subsequent stage T2 of “LAMP 1” in FIG. 2, the second blinking pattern is the same as that in the subsequent stage T2 after the initial stage T1. This is a blinking pattern that turns on and off (flashes) more slowly than one blinking pattern.

  In the first flashing pattern in which the brake lamp 1 is flashed instantaneously at the initial stage T1, the “instantaneous” is a time that a person feels “instantaneously” when he / she looks at the brake lamp 1; About 10 ms or less. For example, it is almost the same as the LED on / off time. That is, as shown in FIG. 3, the rise time T3 for turning on the brake lamp 1 is about 10 ms or less and is substantially vertical. The fall time for turning off the brake lamp 1 is the same as the rise time T3.

  In the second flashing pattern in which the brake lamp 1 flashes slowly in the subsequent stage T2, the “slow” is paired with the “instantaneous”, and as an example, about 200 ms or less. And For example, it is approximately the same as the lighting time of an incandescent bulb. That is, as shown in FIG. 3, the rise time T4 for turning on the brake lamp 1 is about 200 ms or less and has a substantially linear inclination. The fall time for turning off the brake lamp 1 is the same as the rise time T4.

  The blinking control of the brake lamp 1 uses, for example, a pulse wide modulation (PWM) method. In the initial stage T1, the time for which the brake lamp 1 is turned on and off instantaneously in the first blinking pattern is about 1 second or less, preferably about 500 ms to about 1 s. In the initial stage T1, the number of times the brake lamp 1 is turned on and off instantaneously in the first blinking pattern is 2 to 5 times, in this example, 2 times. Further, the number of times that the brake lamp 1 is turned on and off instantaneously in the first blinking pattern in the initial stage T1 is 2 to 5 times, in this example, 2 times, between about 500 ms to about 1 s. is there.

  When the determination unit 5 determines that the vehicle is in a sudden deceleration state based on the detection signal from the deceleration detection unit 2 and the first parameter of the storage unit 4, the determination unit 5 outputs a first blink signal of the storage unit 4. In addition, when the initial stage T1 is counted from the start and it is determined that the initial stage T1 has elapsed based on the count and the second parameter of the storage unit 4, the second flashing signal of the storage unit 4 is output. Is. The object for which the determination unit 5 counts the initial stage T1 from the start is the blinking time of the brake lamp 1 or the number of blinks of the brake lamp 1.

  The lamp driving unit 6 controls the power supplied to the brake lamp 1 based on the blinking signal from the determination unit 5. That is, the lamp driving unit 6 causes the brake lamp 1 to blink in the first blinking pattern in the initial stage T1 by the first blinking signal from the determination unit 5 and the second blinking from the determination unit 5. The brake lamp 1 is blinked in the second blinking pattern in the subsequent stage T2 by a signal.

  The vehicle rapid deceleration indicator lamp device according to the first embodiment is configured as described above. Hereinafter, the operation of the vehicle rapid deceleration indicator lamp device according to the first embodiment, that is, the procedure (steps) of the process of the control device 3 is described. ) Will be described with reference to the flowchart of FIG.

  First, the determination unit 5 of the control device 3 inputs a detection signal from the deceleration detection unit 2 (the determination unit 5 inputs a detection signal S1 from the deceleration detection unit 2). The determination unit 5 of the control device 3 compares the detection signal from the deceleration detection unit 2 with the first parameter stored in the storage unit 4 (the determination unit 5 determines the detection signal and the first of the storage unit 4. Compare with parameters S2).

  Here, the determination unit 5 of the control device 3 determines whether or not the vehicle is in a rapid deceleration state (is the vehicle in a rapid deceleration state? S3). That is, when the value of the detection signal from the deceleration detection unit 2 is less than the determination reference value of the first parameter stored in the storage unit 4, the determination unit 5 of the control device 3 determines that the vehicle is not in a sudden deceleration state. Then, the process returns to the step (S1). On the other hand, when the value of the detection signal from the deceleration detection unit 2 is equal to or greater than the determination reference value of the first parameter stored in the storage unit 4, the determination unit 5 of the control device 3 determines that the vehicle is in a sudden deceleration state. Then, the process proceeds to the next step (S4).

  The determination unit 5 of the control device 3 outputs the first blinking signal stored in the storage unit 4 to the lamp driving unit 6 (the determination unit 5 outputs the first blinking signal of the storage unit 4 to the lamp driving unit 6. S4). The lamp driving unit 6 causes the brake lamp 1 to blink in the first blinking pattern in the initial stage T1 by the first blinking signal from the determination unit 5. As a result, the brake lamp 1 flashes in the first flash pattern in the initial stage T1, that is, turns on and off instantaneously (the brake lamp 1 flashes in the first flash pattern in the initial stage T1 S5).

For example, as shown in FIG. 2, at the time t1 when the vehicle running at 100 km / h starts decelerating and the deceleration reaches about 6 m / s ² or more and suddenly decelerates, the brake lamp 1 is Flashes in the first flashing pattern in the initial stage T1.

  Further, the determination unit 5 of the control device 3 counts the initial stage T1 from the start, and compares the count with the second parameter stored in the storage unit 4 (the determination unit 5 selects the initial stage T1). Is counted from the start, and the count is compared with the second parameter of the storage unit S6).

  Here, the determination unit 5 of the control device 3 determines whether or not the initial stage T1 has passed (whether the initial stage T1 has passed? S7). That is, when the count number counted by the determination unit 5 is less than the determination reference value of the second parameter stored in the storage unit 4, the determination unit 5 of the control device 3 determines that the initial stage T1 has not elapsed. Then, the process returns to the step (S4). On the other hand, when the count number counted by the determination unit 5 is equal to or larger than the determination reference value of the second parameter stored in the storage unit 4, the determination unit 5 of the control device 3 determines that the initial stage T1 has elapsed. Then, the process proceeds to the next step (S8).

  The determination unit 5 of the control device 3 outputs the second flashing signal stored in the storage unit 4 to the lamp driving unit 6 (the determination unit 5 outputs the second flashing signal of the storage unit 4 to the lamp driving unit 6. S8). The lamp driving unit 6 causes the brake lamp 1 to blink in the second blinking pattern in the subsequent stage T2 by the second blinking signal from the determination unit 5. As a result, the brake lamp 1 flashes in the second flashing pattern in the subsequent stage T2, that is, slowly turns on and off (the brake lamp 1 flashes in the second flashing pattern in the subsequent stage T2 S9).

  For example, as shown in FIG. 2, at the time t2 when the brake lamp 1 flashes in the first flashing pattern in the initial stage T1 for about 500 ms to about 1 s or flashes twice, the brake lamp 1 is in the transition stage. Flashes in the second flashing pattern at T2.

  Moreover, the determination part 5 of the control apparatus 3 inputs the detection signal from the deceleration detection part 2 again (the determination part 5 receives detection signal S10 from the deceleration detection part 2). The determination unit 5 of the control device 3 compares the detection signal from the deceleration detection unit 2 with the first parameter stored in the storage unit 4 (the determination unit 5 determines the detection signal and the first of the storage unit 4. Comparison with parameters S11).

  Here, the determination unit 5 of the control device 3 determines again whether or not the vehicle is in a rapid deceleration state (is the vehicle in a rapid deceleration state? S12). That is, when the value of the detection signal from the deceleration detection unit 2 is equal to or greater than the determination reference value of the first parameter stored in the storage unit 4, the determination unit 5 of the control device 3 determines that the vehicle is in a sudden deceleration state. Then, the process returns to the step (S8). As a result, the brake lamp 1 continues to blink in the second blinking pattern. On the other hand, when the value of the detection signal from the deceleration detection unit 2 is less than the determination reference value of the first parameter stored in the storage unit 4, the determination unit 5 of the control device 3 determines that the vehicle is not in a sudden deceleration state. The process proceeds to the next step (S13).

  The determination unit 5 of the control device 3 outputs the extinguishing signal stored in the storage unit 4 to the lamp driving unit 6 (the determining unit 5 outputs the extinguishing signal of the storage unit 4 to the lamp driving unit 6 S13). The lamp driving unit 6 turns off the brake lamp 1 in the blinking state of the second blinking pattern by the turn-off signal from the determination unit 5. As a result, the brake lamp 1 in the blinking state of the second blinking pattern is turned off (the brake lamp 1 is turned off S14).

  For example, as shown in FIG. 2, the brake lamp 1 is turned off at time t3 when the vehicle stops and the vehicle speed becomes 0 km / h. It should be noted that the brake lamp 1 may be turned off when the vehicle is no longer suddenly decelerated without the vehicle speed becoming 0 km / h. Thus, the operation of the vehicle rapid deceleration indicator lamp device according to the first embodiment, that is, the procedure (operation) of the process processing of the control device 3 is completed.

  The vehicle rapid deceleration indicator lamp device according to the first embodiment is configured and operated as described above. Hereinafter, effects of the vehicle rapid deceleration indicator lamp device according to the first embodiment will be described.

  As is apparent from the configuration and operation described above, the vehicular rapid deceleration indicator lamp device according to the first embodiment can achieve the following effects. That is, when the determination unit 5 of the control device 3 determines that the vehicle is in the rapid deceleration state, the brake lamp 1 is turned on and off instantaneously in the first flashing pattern in the initial stage T1, so that the rapid deceleration state of the host vehicle Can be noticed by the driver of the following car, etc., and can contribute to traffic safety. In the vehicle rapid deceleration indicator lamp device according to the first embodiment, the brake lamp 1 is continuously turned on and off more slowly in the second flashing pattern than in the first flashing pattern in the stage T2 after the initial stage T1 has elapsed. The stimulus of the flashing light of the brake lamp 1 given to the driver of the succeeding vehicle who has noticed the sudden deceleration state of the preceding vehicle once and is watching the preceding vehicle can be alleviated. For example, it is compared with the blinking state of the lamp 2 in FIG. 2 (the lamp of the conventional vehicle rapid deceleration indicator lamp device). That is, the conventional lamp 2 flashes instantaneously even after the initial stage T1 and after the stage T2, and there is a risk of stimulating the flashing light of the lamp 2 to the driver of the following vehicle. On the other hand, in the vehicle rapid deceleration indicator lamp device according to the first embodiment, the brake lamp 1 is continuously turned on and off more slowly than the first flashing pattern in the second flashing pattern in the stage T2 after the initial stage T1 has elapsed. Therefore, the stimulation of the flashing light of the brake lamp 1 given to the driver of the following vehicle can be mitigated.

  In the vehicle rapid deceleration indicator lamp device according to the first embodiment, the time for which the brake lamp 1 is instantaneously turned on / off in the first flashing pattern in the initial stage T1 is about 500 ms to about 1 s. Thus, the sudden deceleration state of the host vehicle can be surely noticed, and the stimulation of the flashing light of the brake lamp 1 can be surely mitigated. In other words, it has been proved by experiments that the time until the driver of the following vehicle looking away notices the flashing of the lamp of the preceding vehicle is about 1 second or less. As described above, the vehicular rapid deceleration indicator lamp device according to the first embodiment instantaneously turns on the brake lamp 1 in the first flashing pattern for about 500 ms to about 1 s in the initial stage T1 based on the proof of the experiment. Since it is turned on and off, the driver of the following vehicle can be made aware of the sudden deceleration state of the own vehicle, and the stimulation of the flashing light of the lamp can be alleviated with certainty.

  Further, in the vehicle rapid deceleration indicator lamp device according to the first embodiment, the brake lamp 1 flashes from the flashing time of the brake lamp 1 as a target for the determination unit 5 of the control device 3 to count the initial stage T1 from the start. It can be changed to the number of times. When this count object is changed to the number of times the brake lamp 1 blinks, the vehicle rapid deceleration indicator lamp device according to the first embodiment is similar to the effect when the count object is the blink time of the brake lamp 1 described above. In stage T1, the number of times the brake lamp 1 is turned on and off instantaneously in the first blinking pattern is 2 to 5 times, and in this example, 2 times. Can be noticed, and the stimulation of the flashing light of the lamp can be surely mitigated. In addition, when the count target is changed to the number of times the brake lamp 1 blinks, the vehicle rapid deceleration indicator lamp device according to the first embodiment switches from the first blinking pattern at the initial stage T1 to the second blinking pattern at the subsequent stage T2. Since the determination (initial stage progress determination) is performed based on the number of flashes in the first flashing pattern of the brake lamp 1, the process is simpler than in the case where the above determination is performed based on the flashing time in the first flashing pattern of the brake lamp 1. Therefore, the structure of the control device is simplified, and the manufacturing cost can be reduced. In the vehicular rapid deceleration indicator lamp device according to the first embodiment, the number of times the brake lamp 1 is turned on and off instantaneously in the first flashing pattern in the initial stage T1 is twice between about 500 ms and about 1 s. It may be ~ 5 times.

  Furthermore, in the vehicle rapid deceleration indicator lamp device according to the first embodiment, when the determination unit 5 of the control device 3 determines that the vehicle is in the rapid deceleration state, the first flashing signal of the storage unit 4 is driven by a lamp. In the initial stage T1, the brake lamp 1 is turned on and off instantaneously in the first flashing pattern, so that the driver's driver can notice the sudden deceleration state of the host vehicle, and traffic safety Can contribute. Further, in the vehicular rapid deceleration indicator lamp device according to the first embodiment, the second flashing signal of the storage unit 4 is sent to the lamp driving unit 6 when the determination unit 5 of the active device 3 determines the progress of the initial stage T1. After the passage of the initial stage T1, the brake lamp 1 is continuously turned on and off more slowly than the first flashing pattern in the second flashing pattern after the initial stage T1 has elapsed. The stimulus of the flashing light of the lamp to the driver of the following car that is watching the vehicle can be mitigated.

  Furthermore, in the vehicle rapid deceleration indicator lamp device according to the first embodiment, since the lamp 1 is also used as a brake lamp, the number of parts can be reduced correspondingly, and the manufacturing cost can be reduced.

  6 and 7 show a second embodiment of the vehicle rapid deceleration indicator lamp device according to the present invention. In the figure, the same reference numerals as those in FIGS. 1 to 5 denote the same components.

  As shown in FIG. 6, the vehicle rapid deceleration indicator lamp device according to the second embodiment is configured such that the determination unit 5 of the control device 3 of the vehicle rapid deceleration display lamp device according to the first embodiment is a first determination unit. 7 and the second determination unit 8. When the first determination unit 7 determines that the vehicle is in a sudden deceleration state based on the detection signal from the deceleration detection unit 2 and the first parameter in the storage unit 4, the first blinking signal in the storage unit 4 is sent to the lamp drive unit. 6 is output. When the second determination unit 8 counts the initial stage T1 from the start and determines that the initial stage T1 has elapsed based on the count and the second parameter of the storage unit 4, the second determination unit 8 displays a second flashing signal in the storage unit 4 as a lamp. This is output to the drive unit 6.

  Hereinafter, the operation of the vehicle rapid deceleration indicator lamp device in the second embodiment, that is, the procedure (operation) of the process processing of the control device 3 will be described with reference to the flowchart of FIG.

  First, the first determination unit 7 of the control device 3 inputs a detection signal from the deceleration detection unit 2 (the first determination unit 7 inputs a detection signal from the deceleration detection unit 2 S101). The first determination unit 7 of the control device 3 compares the detection signal from the deceleration detection unit 2 with the first parameter stored in the storage unit 4 (the first determination unit 7 compares the detection signal with the storage unit). Comparison with the first parameter of 4 S102).

  Here, the first determination unit 7 of the control device 3 determines whether or not the vehicle is in a rapid deceleration state (is the vehicle in a rapid deceleration state? S103). That is, when the value of the detection signal from the deceleration detection unit 2 is less than the determination reference value of the first parameter stored in the storage unit 4, the first determination unit 7 of the control device 3 determines that the vehicle is not in a sudden deceleration state. Judgment is made, and the process returns to the step (S101). On the other hand, when the value of the detection signal from the deceleration detection unit 2 is equal to or greater than the determination reference value of the first parameter stored in the storage unit 4, the first determination unit 7 of the control device 3 is in the state of rapid deceleration. The process proceeds to the next step (S104).

  The first determination unit 7 of the control device 3 outputs the first blinking signal stored in the storage unit 4 to the lamp driving unit 6 (the first determination unit 7 drives the first blinking signal of the storage unit 4 by lamp driving. Output to unit 6 S104). The lamp driving unit 6 causes the brake lamp 1 to blink in the first blinking pattern in the initial stage T1 by the first blinking signal from the first determination unit 7. As a result, the brake lamp 1 flashes in the first flashing pattern in the initial stage T1, that is, turns on and off instantaneously (the brake lamp 1 flashes in the first flashing pattern in the initial stage T1 S105).

For example, as shown in FIG. 2, at the time t1 when the vehicle running at 100 km / h starts decelerating and the deceleration reaches about 6 m / s ² or more and suddenly decelerates, the brake lamp 1 is Flashes in the first flashing pattern in the initial stage T1.

  The second determination unit 8 of the control device 3 counts the initial stage T1 from the start, and compares the count with the second parameter stored in the storage unit 4 (the second determination unit 8 The initial stage T1 is counted from the start, and the count is compared with the second parameter of the storage unit 4 (S106).

  Here, the second determination unit 8 of the control device 3 determines whether or not the initial stage T1 has passed (whether the initial stage T1 has passed? S107). That is, when the count number counted by the second determination unit 8 is less than the determination reference value of the second parameter stored in the storage unit 4, the second determination unit 8 of the control device 3 has passed the initial stage T1. It judges that there is no, and it returns to the said process (S104). On the other hand, when the count number counted by the second determination unit 8 is equal to or larger than the determination reference value of the second parameter stored in the storage unit 4, the second determination unit 8 of the control device 3 is one in which the initial stage T1 has elapsed. The process proceeds to the next step (S108).

  The second determination unit 8 of the control device 3 outputs the second flashing signal stored in the storage unit 4 to the lamp driving unit 6 (the second determination unit 8 drives the second flashing signal of the storage unit 4 by lamp driving. Output to unit 6 S108). The lamp driving unit 6 causes the brake lamp 1 to blink in the second blinking pattern in the subsequent step T2 by the second blinking signal from the second determination unit 8. As a result, the brake lamp 1 flashes in the second flashing pattern in the subsequent stage T2, that is, gradually turns on and off (the brake lamp 1 flashes in the second flashing pattern in the subsequent stage T2 S109).

  For example, as shown in FIG. 2, at the time t2 when the brake lamp 1 flashes in the first flashing pattern in the initial stage T1 for about 500 ms to about 1 s or flashes twice, the brake lamp 1 is in the transition stage. Flashes in the second flashing pattern at T2.

  Moreover, the 1st judgment part 7 of the control apparatus 3 inputs the detection signal from the deceleration detection part 2 again (the 1st judgment part 7 inputs detection signal S110 from the deceleration detection part 2). The second determination unit 7 of the control device 3 compares the detection signal from the deceleration detection unit 2 with the first parameter stored in the storage unit 4 (the first determination unit 7 compares the detection signal with the storage unit). 4 and the first parameter (S111).

  Here, the first determination unit 7 of the control device 3 determines again whether or not the vehicle is in a rapid deceleration state (is the vehicle in a rapid deceleration state? S112). That is, when the value of the detection signal from the deceleration detection unit 2 is equal to or greater than the determination reference value of the first parameter stored in the storage unit 4, the first determination unit 7 of the control device 3 is in a state of rapid deceleration. It returns to the said process (S108). As a result, the brake lamp 1 continues to blink in the second blinking pattern. On the other hand, when the value of the detection signal from the deceleration detection unit 2 is less than the determination reference value of the first parameter stored in the storage unit 4, the first determination unit 7 of the control device 3 determines that the vehicle is not in a sudden deceleration state. Determination is made and the process proceeds to the next step (S113).

  The first determination unit 7 of the control device 3 outputs the turn-off signal stored in the storage unit 4 to the lamp drive unit 6 (the first determination unit 7 outputs the turn-off signal of the storage unit 4 to the lamp drive unit 6. S113). The lamp driving unit 6 turns off the brake lamp 1 in the blinking state of the second blinking pattern by the turn-off signal from the first determination unit 7. As a result, the brake lamp 1 in the blinking state of the second blinking pattern is turned off (the brake lamp 1 is turned off S114).

  For example, as shown in FIG. 2, the brake lamp 1 is turned off at time t3 when the vehicle stops and the vehicle speed becomes 0 km / h. Thus, the operation of the vehicle rapid deceleration indicator lamp device according to the first embodiment, that is, the procedure (operation) of the process processing of the control device 3 is completed.

  Since the vehicle rapid deceleration indicator lamp device according to the second embodiment is configured and operated as described above, the same effects as those of the vehicle rapid deceleration indicator lamp device according to the first embodiment can be achieved. That is, in the vehicular rapid deceleration indicator lamp device according to the second embodiment, when the first determination unit 7 determines that the vehicle is in the rapid deceleration state, the first blinking signal in the storage unit 4 is sent to the lamp driving unit 6. In the initial stage T1, the brake lamp 1 is turned on and off instantaneously in the first blinking pattern, so that the driver's driver can notice the sudden deceleration state of the vehicle and contribute to traffic safety. Can do. In addition, in the vehicle rapid deceleration indicator lamp device according to the second embodiment, when the second determination unit 8 determines that the initial stage T2 has elapsed, the second blinking signal in the storage unit 4 is output to the lamp driving unit 6. After the initial stage T1, the brake lamp 1 is continuously turned on and off more slowly than the first flashing pattern in the second flashing pattern after the initial stage T1. It is possible to alleviate the stimulation of the flashing light of the lamp that is given to the driver of the succeeding vehicle.

  In particular, in the vehicle rapid deceleration indicator lamp device according to the second embodiment, the first determination unit 7 determines the rapid deceleration state of the vehicle, and the second determination unit 8 determines the progress of the initial stage. The processing speed can be increased compared with the case where the determination unit 5 determines the sudden deceleration state of the vehicle and the progress of the initial stage, and the processing capability of the control device is improved accordingly.

  Hereinafter, examples other than the first and second embodiments will be described. In the first and second embodiments, a brake lamp is used as the lamp 1. However, in the present invention, the lamp is a lamp other than the brake lamp, and is a lamp disposed at a predetermined position of the vehicle, for example, an existing lamp, a dedicated lamp, or a combination of these lamps.

The collision prevention system outputs an operation signal (detection signal) when the collision prevention system 27 is activated. The engine speed sensor detects the engine speed and outputs a detection signal thereof.

  Further, in the first and second embodiments, the lighting rise and extinguishing fall of the brake lamp 1 in the second blinking pattern are linearly inclined as shown in FIGS. 2, 3, and 4 (A). is there. However, in the present invention, the lighting rise and extinguishing fall of the brake lamp 1 in the second blinking pattern may have a curved inclination as shown in FIG. 4 (B), or in FIG. 4 (C). As shown, a stepped slope may be used.

  Furthermore, in the first and second embodiments, the flashing of the brake lamp 1 in the second flashing pattern is performed gently both at the rising and falling edges. However, in the present invention, the flashing of the brake lamp 1 in the second flashing pattern may be performed gradually at least one of lighting rising and lighting extinction falling.
