Description

  The present invention relates to a side illuminating lamp system, and more particularly, to a side illuminating lamp system that turns on a side illuminating lamp in accordance with the operating status of a direction indicator.

  Conventionally, some vehicles are provided with side illumination lamps on the side of a bumper attached to the front of the vehicle. This side illumination lamp is characterized by being lit in conjunction with the operation of the direction indicator. However, in order for the direction indicator to blink the lamp, the side-illumination lamp can obtain a signal directly from the signal line of the direction indicator in order to keep it on continuously so as not to be affected by the blinking of the direction indicator. A method for determining whether the side illumination lamp is turned on or off is common.

  This side illumination lamp greatly contributes to securing the side view. In particular, it can be mounted on an old vehicle that does not use a high-illuminance light source such as HID or LED. Therefore, it is possible to improve the visibility of the side confirmation when the vehicle is driven for the occupant, and for the passerby, it leads to the early detection of the vehicle coming from the side, greatly contributing to accident prevention. For this reason, many side illumination lamps have been set not only as standard equipment for vehicles, but also as order-installation equipment installed at dealers.

  However, when retrofitting with custom mounting, it is necessary to connect the signal line of the direction indicator to the side illumination lamp, so it is necessary to pass a new harness through the vehicle body, which is cumbersome. The wages were also increasing.

Therefore, as shown in Patent Document 1, a smoothing circuit that smoothes the blinking signal of the direction indicator, a transistor that is provided at the subsequent stage of the smoothing circuit and that continuously turns on the side illumination lamp by inputting the smoothing signal, and smoothing A lighting circuit that has a constant voltage element that stabilizes the voltage input to the smoothing circuit, which is provided in the previous stage of the circuit, converts the blinking signal that blinks the direction indicator into a continuous lighting signal and continuously lights the side illumination lamp By turning off the side illumination lamp after a predetermined time from the stop of the blinking signal input, the off-delay time of the side illumination lamp can be made constant even if the voltage of the blinking signal for the direction indicator fluctuates. Possible technologies have been proposed.

  However, according to Patent Document 1, the blinking cycle of the direction indicator greatly varies depending on the vehicle type and the vehicle environment. Therefore, it is necessary to set the off-delay time with the longest cycle in order to have versatility. For this reason, the off-delay time from the completion of blinking of the lamp of the direction indicator to the extinguishing of the side-illumination lamp has occurred at a maximum of about 700 ms, so that it can be recognized that the extinguishing timing is delayed. Therefore, there is a problem that the user feels uncomfortable.

  In recent years, it has become difficult to obtain a driving signal for a direction indicator as the computerization of vehicles progresses. Further, a method of arranging a plurality of switches in a grid and reading them sequentially is adopted, and there is a tendency to reduce the number of wires. Therefore, it is necessary to operate the side illumination lamp by acquiring the blinking signal of the direction indicator without passing a new wiring for the signal of the direction indicator through the vehicle body.

  The present invention has been made in view of the above circumstances, and without passing a new wiring for obtaining a signal of the direction indicator through the vehicle body, the side illumination lamp with respect to the completion timing of the blinking operation of the direction indicator It is an object of the present invention to provide a side illumination system that does not give a sense of incongruity to a user without causing a significant delay in the turn-off timing.

  In order to solve the above-mentioned problem, in the side illumination lamp system of the present invention comprising a direction indicator and a side illumination lamp that illuminates the side of the vehicle in accordance with lighting of the direction indicator, the direction indicator When the indicator is activated and blinks, the measuring means that measures at least one of the blinking lighting time and the extinguishing time and sets the measuring time, and the operation of the direction indicator according to the measuring time measured by the measuring means And determining means for determining whether or not the operation of the direction indicator has been completed by the determining means, and switching means for turning off the side illumination lamp. To do.

  According to this configuration, it is possible to determine whether or not the blinking operation of the direction indicator is completed according to the measurement time obtained by measuring at least one of the lighting time and the extinguishing time among the blinking times of the direction indicator. . And when it is judged that the blinking operation of the direction indicator is completed, the side illumination lamp is turned off immediately, so that the side illumination lamp can be smoothly turned off after the lighting of the direction indicator completes blinking. Can do. In addition, since the blinking time of the direction indicator is measured to determine the blinking operation status of the direction indicator, it is smooth after the lighting of the direction indicator completes blinking without being affected by the vehicle type or vehicle environment. Since the side illumination lamp can be turned off, the off-delay time of the side illumination lamp can be shortened. Further, the blinking pulse signal of the direction indicator necessary for measuring the blinking time of the direction indicator is a signal wired to the direction indicator without passing a new wiring for obtaining the direction indicator signal through the vehicle body. Since it is only necessary to branch the line and connect it to the side illumination lamp system of the present invention, even when the side illumination lamp is retrofitted, the work becomes easy and the labor paid by the user can be reduced. Thus, the willingness to wear can be improved.

  Furthermore, since the means for obtaining the direction indicator signal has a different electrical connection configuration for each vehicle type, it is necessary to prepare a plurality of side illumination lamp connection systems with various specifications. By using the side illumination lamp system of the present invention, it is possible to use only one specification, so that the manufacturing cost and management cost can be reduced in the production of the side illumination lamp. As a result, the user's willingness to attach to the side illuminating lamp is improved, and the penetration rate of the side illuminating lamp is improved, thereby increasing the safety of the vehicle and greatly contributing to accident prevention. .

  Further, in addition to the above-described invention, a calculation unit that calculates an average value of lighting times from a plurality of lighting times of the direction indicator among the measurement times measured by the measurement unit, and the lighting calculated by the calculation unit Storage means for storing an average value of time, and the determination means, when the lighting time measured by the measurement means is shorter than a predetermined time than the average value of the lighting time stored in the storage means, It is determined that the operation of the direction indicator is completed.

  According to this configuration, when the blinking operation of the direction indicator is completed during lighting, since the lighting time is shorter than the average lighting time calculated, the measured lighting time average value is calculated. If it is shorter than the predetermined time, it can be determined that the blinking operation of the direction indicator has been completed, and the side illumination lamp can be quickly turned off. In addition, each lighting time during the blinking operation of the direction indicator varies depending on the ambient temperature and component characteristics, so the average value of the lighting time is taken to improve the accuracy of the completion timing in the blinking operation of the direction indicator. Can be made. Thereby, even when the blinking operation of the direction indicator is completed during lighting, the side illumination lamp can be smoothly turned off, and a side illumination system that does not give the user a sense of incongruity can be provided.

  Further, in addition to the above-described invention, a calculation unit that calculates an average value of the turn-off time from a plurality of turn-off times of the direction indicator among the measurement times measured by the measurement unit, and the light extinction calculated by the calculation unit Storage means for storing an average value of time, and the determination means, when the turn-off time measured by the measurement means is longer than the average value of the turn-off time stored in the storage means, It is determined that the operation of the direction indicator is completed.

  According to this configuration, when the blinking operation of the direction indicator is completed while the lights are turned off, the average time of the turn-off time calculated is longer than the average value of the turn-off time calculated. If it is longer than the predetermined time, it is determined that the blinking operation of the direction indicator is completed, and the side illumination lamp can be quickly turned off. In addition, each turn-off time during blinking operation of the direction indicator varies depending on the ambient temperature and component characteristics. Therefore, taking the average value of the turn-off time improves the accuracy of the completion timing of blinking operation of the direction indicator. Can be made. This eliminates the need to set a long off-delay time for the side illumination lamp. Therefore, the side illumination lamp can be turned off smoothly after the lamp of the direction indicator completes blinking without being affected by the vehicle type or the vehicle environment, and the off-delay time can be shortened.

  In addition to the above-described invention, the information processing apparatus further includes a storage unit that stores at least one of a predetermined first fixed value and a second fixed value, and the determination unit includes the measurement time measured by the measurement unit. Among them, when the lighting time of the direction indicator is shorter than the first fixed value stored in the storage means, or the turn-off time of the direction indicator of the measurement time measured by the measuring means is stored. When it is longer than the second fixed value stored in the means, it is determined that the operation of the direction indicator is completed.

  According to this configuration, by setting the first fixed value as the threshold value of the minimum period of the lighting time, when the measured lighting time of the direction indicator is shorter than the first fixed value, the direction indicator flashes. The side illumination lamp can be turned off by judging that the operation has been completed. In addition, by setting the second fixed value as the threshold value of the maximum turn-off time, when the turn-off time of the measured direction indicator is longer than the second fixed value, the blinking operation of the direction indicator is completed. It can be judged that the side illumination lamp can be turned off. This eliminates the need to set a long off-delay time for the side illumination lamp. Therefore, it is possible to smoothly turn off the side illumination lamp after the lamp of the direction indicator completes blinking without being affected by the vehicle type or the vehicle environment, and the off delay time of the direction indicator can be shortened. it can.

  Further, in addition to the above-described invention, a calculation unit that calculates an average value of measurement times from a plurality of the measurement times measured by the measurement unit, an average value of the measurement times calculated by the calculation unit, and the measurement unit And a storage means for storing a predetermined number of measurements, and the determination means, when the measurement count stored in the storage means is greater than or equal to a predetermined count, the measurement means The measurement time measured by the means is compared with the average value of the measurement times stored in the storage means. If the number of measurements stored in the storage means is less than a predetermined number, the measurement time is measured by the measurement means. The measured time is compared with the fixed value stored in the storage means to determine whether or not the operation of the direction indicator is completed.

  According to this configuration, if the number of measurements measured by the measuring means is equal to or greater than the predetermined number, whether the blinking operation of the direction indicator is completed by comparing the average value calculated by the calculating means with the measured measurement time. The side illumination lamp can be turned off according to the determination result. Further, when the number of measurements measured by the measuring means is less than the predetermined number, the fixed value stored in the storage means is compared with the measured measurement time to determine whether or not the blinking operation of the direction indicator is completed. Thus, the side illumination lamp can be turned off according to the determination result. Thereby, for example, when the cycle and duty of the blinking signal pulse generated by the blinking waveform generation circuit of the direction indicator at the lighting time and the turn-off time immediately after the start of blinking operation of the direction indicator are not stable, To improve the accuracy of the completion timing of blinking operation of the direction indicator by using a fixed value instead of using the average value calculated from the initial lighting time and extinguishing time when there is little variation in measurement time Can do. In addition, when the blinking signal pulse of the direction indicator is stable or when the number of measurements is large and the variation in the measurement time is small, the accuracy of the completion timing in the blinking operation of the direction indicator is used by using the calculated average value. Can be improved. Therefore, it is possible to smoothly turn off the side illumination lamp after the lamp of the direction indicator completes blinking without being affected by the vehicle type or the vehicle environment, and the off delay time of the direction indicator can be shortened. it can.

  According to the present invention, by determining whether or not the blinking operation of the direction indicator is completed, according to the measurement time of measuring the lighting time and the extinguishing time or at least one of the blinking time of the direction indicator, The side that does not give a sense of incongruity to the user without passing a new wiring for acquiring the signal of the direction indicator through the vehicle body, without the delay in the timing of turning off the side illumination lamp with respect to the completion timing of the blinking operation of the direction indicator An illumination lamp system can be provided.

  FIG. 3 is an explanatory view schematically showing the side illumination lamp system according to the first embodiment of the present invention. A control circuit 31 is provided in the case 30 shown in FIG. 2, and the connection state of the control circuit 31 is schematically shown in FIG. As shown in FIG. 3, a direction indicator (left) signal line 26L, a direction indicator (right) signal line 26R, and a headlight (H / L) signal are input to the input terminal shown on the left side of the control circuit 31. The line 27, the lamp power supply line 28, and the GND line 29 are connected.

  Further, the direction indicator (left) signal line 26L connected to the direction indicator (left) 13L is branched and connected to the input terminal of the control circuit 31. Similarly, the direction indicator (right) signal line 26R connected to the direction indicator (right) 13R is branched and connected to the input terminal of the control circuit 31. In FIG. 3, the left and right side illumination lamps 20 are controlled by one control circuit 31, but a control circuit 31 may be provided for each of the left and right side illumination lamps 20.

  FIG. 4 shows a lamp state of a side irradiation lamp to which the side irradiation lamp system according to the first embodiment of the present invention is applied, and a lamp state of a side irradiation lamp to which the side irradiation lamp system according to the conventional example is applied. It is the timing chart which compared these. In FIG. 4, the vertical axis indicates signal information received from the signal line connected to the input terminal of the control circuit 31, the lighting state of the side illumination lamp connected to the output terminal, and the like. The horizontal axis is the time axis (t).

  The headlight signal 51 is a pulse signal input to the control circuit 31 from the headlight signal line 27L. The upper row is a signal for turning on the headlight, and the lower row is a signal for turning off the headlight. It is assumed that the headlight ON state is 12V and the headlight OFF state is a pulse signal that sets 0V.

  The direction indicator switch state 52 indicates the switch state of the direction indicator that is changed by the operation of the occupant in the vehicle control unit, and the upper portion indicates the switch ON state and the lower portion indicates the switch OFF state. Note that the control circuit 31 of the present invention has not acquired a signal indicating the direction indicator switch state.

  The direction indicator lamp signal 53 is a pulse signal input to the control circuit 31 from the direction indicator signal line 26. The upper row shows the lighting state, and the lower row shows the lighting state. The lighting state is 12V, the headlight extinguishing state is 0V, the lighting state and the extinguishing time are repeatedly flashed, the cycle is 85.7 times / min, and the duty ratio is 1: 1.

  The side illumination lamp lighting state 54 indicates an ideal state in which the side illumination lamp 20 is turned on or off according to the states of the headlight signal 51 and the direction indicator lamp signal 53. The upper row indicates that the side illumination lamp 20 is turned on, and the lower row indicates that the side illumination lamp 20 is turned off. That is, when the headlight signal 51 is ON, and the turn signal lamp signal 53 is in a blinking state that repeats a lighting state and a light-off state, the side illumination lamp 20 is turned on, and the others are turned off. It is said.

  The lamp state 60 of the side illumination lamp 20 in the conventional example A shows a case where wiring is provided from the control unit of the vehicle which is the conventional example and connected to the side illumination lamp 20. In this case, since the information of the direction indicator switch state 52 can be acquired, the lamp state 60 of the side illumination lamp 20 in the conventional example A can obtain the same time chart as the direction indicator switch state 52. Therefore, the lamp state 60 of the side illumination lamp 20 in the conventional example A is the same time chart as the side illumination lamp lighting availability state 54 showing an ideal state in which the side illumination lamp 20 is turned on or off. As a result, the side illumination lamp 20 can be turned off without delaying the completion of the operation of the direction indicator 13, but a dedicated wiring must be newly passed through the vehicle body, which is cumbersome and labor-intensive. It is increasing.

The lamp state 70 of the side illuminating lamp 20 in the conventional example B shows a case of the side illuminating lamp system of Patent Document 1 as a conventional example. In this case, if the predetermined time (off delay time) has elapsed since the turn-on state of the turn signal lamp signal 53 is changed to the turn-off state, it is determined that the turn indicator 13 has completed the blinking operation, and the side light 20 Turn off the light. At this time, since the predetermined time greatly varies depending on the vehicle type and the vehicle environment, the ideal time for turning on or off the side illumination lamp 20 is shown in order to set the longest period in order to have versatility. The off-delay time of t ₀ B shown in FIG. 4 occurs with respect to the side illumination lamp lighting availability state 54, and a large delay occurs in the timing of turning off the side illumination lamp.

The lamp state 80 of the side illuminating lamp 20 in the first embodiment indicates a case of the side illuminating lamp system in the first embodiment. In the first embodiment, the control circuit 31 measures the lighting time (t ₀ 1) simultaneously with the start of blinking of the direction indicator lamp signal 53. At this time, when the lighting time (t ₀ 1) is smaller than the fixed value k1 compared to the fixed value k1, it is determined that the operation of the direction indicator 13 is completed, and when the lighting time is equal to or longer than the fixed value k1, It is determined that the device 13 is in operation. Here, since the lighting time (t ₀ 1) is larger than the fixed value k1, it is determined that the direction indicator 13 is in operation, and the lighting time (t ₀ 1) is provided in the control circuit 31. To remember.

Next, the control circuit 31 measures the second lighting time (t ₀ 2) of the blinking signal of the direction indicator lamp signal 53. At this time, when the lighting time (t ₀ 2) is smaller than the lighting time (t ₀ 1) stored in the memory plus a predetermined value in consideration of variation, it is determined that the operation of the direction indicator 13 is completed. If it is larger than the value obtained by adding the predetermined value, it is determined that the direction indicator 13 is in operation. Here, since the lighting time (t ₀ 2) is larger than the lighting time (t ₀ 1) stored in the memory plus a predetermined value considering variation, it is determined that the direction indicator 13 is in operation. Then, the lighting time (t ₀ 2) is stored in a memory provided in the control circuit 31. At this time, the control circuit 31 calculates the average value (t _a 1) of the lighting time (t ₀ 1) stored in advance and the second lighting time (t ₀ 2) measured previously and stores it in the memory. To do.

t _a 1 = (t ₀ 1 + t ₀ 2) / 2

Next, the control circuit 31 measures the third lighting time (t ₀ 3) of the blinking signal of the direction indicator lamp signal 53. At this time, if the lighting time (t ₀ 3) is smaller than the average value (t _a 1) stored in the memory plus a predetermined value considering variation, it is determined that the operation of the direction indicator 13 is completed. If it is larger than the value obtained by adding the predetermined value, it is determined that the direction indicator 13 is in operation. Here, since the lighting time (t ₀ 3) is larger than the average value (t _a 1) stored in the memory plus a predetermined value considering variation, it is determined that the direction indicator 13 is in operation. The lighting time (t ₀ 3) is stored in a memory provided in the control circuit 31. At this time, the control circuit 31 calculates the first lighting time (t ₀ 1) and the second lighting time (t ₀ 2) stored in advance, and the third lighting time (t ₀ 3) measured previously. An average value (t _a 2) is calculated.

t _a 2 = (t ₀ 1 + t ₀ 2 + t ₀ 3) / 3

Later, repeatedly, the lighting time of the immediately preceding measured (t 0 _n) is the larger than a value obtained by adding a predetermined value in consideration of variation in the average value stored in the memory (t a _{n -2),} the direction indication By determining that the device 13 is in operation, the lighting time (t ₀ n) is stored in a memory provided in the control circuit 31, and the average value is calculated again (t _a n ₋₁ ). The accuracy of the average value is increased, and the blinking state of the direction indicator can be accurately grasped.

t _a n ₋₁ = (t ₀ 1 + t ₀ 2 + t ₀ 3+... + t ₀ n) / n

Here, the case where the blinking operation is completed in the lighting time during the blinking operation in the direction indicator lamp signal 53 will be described. The control circuit 31 measures the fourth lighting time (t ₀ 4) of the blinking signal of the direction indicator lamp signal 53. At this time, since the lighting time (t ₀ 4) is smaller than the average value (t _a 2) stored in the memory plus a predetermined value considering variation, it is determined that the operation of the direction indicator 13 is completed. be able to. Therefore, the side illumination lamp lighting availability state 54 determines that lighting is prohibited and turns off the side illumination lamp 20 of the first embodiment. At this time, the lighting time and average value stored in the memory in the control circuit 31 are cleared.

As a result, the lamp state 80 of the side illumination lamp of the first embodiment can shorten the off-delay time (t ₀ B) as compared with the lamp state 70 of the side illumination lamp of the conventional example B. This is a time chart close to the side illumination lamp lighting availability state 54 showing an ideal state in which the side illumination lamp 20 is turned on or off. Therefore, it is possible to provide a side illumination system that does not give the user a sense of incongruity.

  FIG. 5 is a timing chart showing a direction indicator lamp state in the side illumination system according to the first embodiment of the present invention. In FIG. 5, a method of calculating the average value of the lighting time during the blinking operation of the direction indicator lamp signal 53 when determining whether or not the side illumination lamp shown in FIG. 4 is turned on will be described in detail.

  As shown in FIG. 5, even when the blinking operation of the direction indicator lamp signal 53 is long, the measured lighting time is used in order to calculate the average value in order. The average value calculated when the control circuit 31 determines that the blinking operation of the direction indicator 13 continues after measuring the lighting time of 7 times is as follows.

t _a 6 = (t ₀ 1 + t ₀ 2 + t ₀ 3 + t ₀ 4 + t ₀ 5 + t ₀ 6 + t ₀ 7) / 7

That is, for the lighting times after the third time, the average value stored in the memory of the control circuit 31 is compared to determine whether or not the blinking operation of the direction indicator 13 is completed. The first lighting time is determined as to whether or not the blinking operation of the direction indicator 13 is completed as compared with the fixed value k1, but is not particularly limited. For example, instead of the fixed value k1, the last lighting time (t ₀ 0) at the time of the blinking operation of the previous direction indicator lamp signal 53 and the average of the lighting time at the time of the blinking operation of the previous direction indicator lamp signal 53 are averaged. A value may be used.

Further, regarding the second lighting time (t ₀ 2), it is determined whether or not the blinking operation of the direction indicator 13 is completed as compared with the first lighting time (t ₀ 1). Not limited. Since the first lighting time is immediately after the start of blinking, the cycle is likely to be unstable. For example, instead of the first lighting time (t ₀ 1), the fixed value k1, the previous turn signal lamp signal 53 You may use the last lighting time (t0 ₀ ) at the time of blinking operation, or the average value of the lighting time at the time of blinking operation of the last direction indicator lamp signal 53.

Also, for the third and subsequent lighting times, the first lighting time (t ₀ 1) is not used for calculating the average value, for example, a fixed value k1, and the previous turn signal lamp signal 53 is blinking. The average value of the lighting time may be calculated by substituting the last lighting time (t ₀ 0) or the average value of the lighting time during the previous blinking operation of the direction indicator lamp signal 53. By the way, instead of the first lighting time (t ₀ 1), the average value when the last lighting time (t ₀ 0) during the blinking operation of the previous turn signal lamp signal 53 is used is as follows: Become.

t _a 6 = (t ₀ 0 + t ₀ 2 + t ₀ 3 + t ₀ 4 + t ₀ 5 + t ₀ 6 + t ₀ 7) / 7

  Thus, according to the first embodiment, when the blinking operation of the direction indicator is completed during lighting, the measured lighting time is calculated because the lighting time is shorter than the average lighting time calculated. When the average lighting time is shorter than a predetermined time, it is determined that the blinking operation of the direction indicator is completed, and the side illumination lamp can be turned off quickly. In addition, each lighting time during the blinking operation of the direction indicator varies depending on the ambient temperature and component characteristics, so the average value of the lighting time is taken to improve the accuracy of the completion timing in the blinking operation of the direction indicator. Can be made. Thereby, even when the blinking operation of the direction indicator is completed during lighting, the side illumination lamp can be smoothly turned off, and a side illumination system that does not give the user a sense of incongruity can be provided.

  Next, a second embodiment of the present invention will be described.

  FIG. 6 shows a lamp state of a side illuminating lamp to which a side illuminating lamp system according to a second embodiment of the present invention is applied and a lamp state of a side illuminating lamp to which a side illuminating lamp system according to a conventional example is applied. It is the timing chart which compared these. FIG. 6 corresponds to FIG. 4 of the first embodiment of the present invention, and the description is omitted when the content is the same.

In FIG. 6, the lamp state 90 of the side illumination lamp 20 in the second embodiment indicates a case of the side illumination lamp system in the second embodiment. In the second embodiment, the control circuit 31 measures the turn-off time (t ₁ 1) after the turn-on operation of the direction indicator lamp signal 53. At this time, if the turn-off time (t ₁ 1) is larger than the fixed value k2 compared to the fixed value k2, it is determined that the blinking operation of the direction indicator 13 is completed, and if it is equal to or less than the fixed value k2, the direction The indicator 13 determines that the blinking operation is in progress. Here, since the turn-off time (t ₁ 1) is smaller than the fixed value k2, it is determined that the direction indicator 13 is in operation, and the turn-off time (t ₁ 1) is provided in the control circuit 31. To remember.

Next, the control circuit 31 measures the second turn-off time (t ₁₂ ) of the blinking signal of the direction indicator lamp signal 53. At this time, when the turn-off time (t ₁ 2) is longer than a value obtained by adding a predetermined value considering variation to the turn-off time (t ₁ 1) stored in the memory, it is determined that the operation of the direction indicator 13 is completed. If it is smaller, it is determined that the direction indicator 13 is in operation. Here, since the turn-off time (t ₁ 2) is smaller than a value obtained by adding a predetermined value considering variation to the turn-off time (t ₁ 1) stored in the memory, it is determined that the direction indicator 13 is in operation. The turn-off time (t ₁ 2) is stored in a memory provided in the control circuit 31. At this time, the control circuit 31 calculates an average value (t _b 1) of the extinguishing time (t ₁ 1) stored in advance and the second extinguishing time (t ₁ 2) measured previously and stores it in the memory. To do.

t _b 1 = (t ₁ 1 + t ₁ 2) / 2

Next, the control circuit 31 measures the third turn-off time (t ₁₃ ) of the blinking signal of the direction indicator lamp signal 53. At this time, if the turn-off time (t ₁ 3) is longer than the average value (t _b 1) stored in the memory plus a predetermined value that takes variation into account, the blinking operation of the direction indicator 13 is completed. If it is determined that the direction indicator 13 is smaller, it is determined that the direction indicator 13 is blinking. Here, since the turn-off time (t ₁ 3) is smaller than the average value (t _b 1) stored in the memory plus a predetermined value considering variation, it is determined that the direction indicator 13 is in operation. Then, the turn-off time (t ₁₃ ) is stored in a memory provided in the control circuit 31. At this time, the control circuit 31 uses the first turn-off time (t ₁ 1) and the second turn-on time (t ₁ 2) stored in advance and the third turn-off time (t ₁ 3) measured previously. An average value (t _b 2) is calculated.

t _b 2 = (t ₁ 1 + t ₁ 2 + t ₁ 3) / 3

Thereafter, when the turn-off time (t ₁ n) immediately before the measurement is repeated is smaller than the average value (t _b n ₋₂ ) stored in the memory plus a predetermined value considering variation, the direction indication By determining that the device 13 is in operation, storing the extinguishing time (t ₁ n) in a memory provided in the control circuit 31, and calculating the average value (t _b n ₋₁ ) again. The accuracy of the average value is increased, and the blinking state of the direction indicator can be accurately grasped.

t _b n ₋₁ = (t ₁ 1 + t ₁ 2 + t ₁ 3+... + t ₁ n) / n

Here, the case where the blinking operation is completed in the turn-off time during the blinking operation in the direction indicator lamp signal 53 will be described. The control circuit 31 measures the fourth turn-off time (t ₁₄ ) of the blinking signal of the direction indicator lamp signal 53. At this time, when the turn-off time (t ₁₄ ) becomes larger than a value (t ₁ C) obtained by adding a predetermined value considering variation to the average value (t _b 2) stored in the memory, the direction indicator 13 It can be determined that the operation of is completed. Therefore, the side illumination lamp lighting availability state 54 determines that lighting is prohibited, and turns off the side illumination lamp 20 of the second embodiment. At this time, the turn-off time and average value stored in the memory in the control circuit 31 are cleared.

As a result, compared to the off-delay time (t ₁ B) of the lamp state 70 of the side irradiation lamp of the conventional example B, the off-delay time (t ₁ C) of the lamp state 90 of the side irradiation lamp of the second embodiment. Therefore, the time chart is close to the side illumination lamp lighting enable / disable state 54 showing an ideal state in which the side illumination lamp 20 is turned on or off. Therefore, it is possible to provide a side illumination system that does not give the user a sense of incongruity.

  FIG. 7 is a timing chart showing the direction indicator lamp state in the side illumination lamp system according to the second embodiment of the present invention. FIG. 7 corresponds to FIG. 5 of the first embodiment of the present invention.

  As shown in FIG. 7, even when the blinking operation of the direction indicator lamp signal 53 is long, the measured turn-off time is sequentially used for calculating the average value. The average value calculated when the control circuit 31 determines that the blinking operation of the direction indicator 13 continues after measuring the extinguishing time seven times is as follows.

t _b 6 = (t ₁ 1 + t ₁ 2 + t ₁ 3 + t ₁ 4 + t ₁ 5 + t ₁ 6 + t ₁ 7) / 7

That is, for the third and subsequent turn-off times, the average value stored in the memory of the control circuit 31 is compared to determine whether or not the blinking operation of the direction indicator 13 has been completed. Regarding the first turn-off time, it is determined whether or not the blinking operation of the direction indicator 13 is completed as compared with the fixed value k2, but is not particularly limited. For example, instead of the fixed value k2, the last turn-off time (t ₁₀ ) when the previous turn signal lamp signal 53 blinks and the average turn-off time when the last turn signal lamp signal 53 blinks are averaged. A value may be used.

Further, regarding the second turn-off time (t ₁ 2), it is determined whether or not the blinking operation of the direction indicator 13 is completed as compared with the first turn-off time (t ₁ 1). Not limited. Since the first turn-off time is immediately after the start of blinking, the cycle is likely to be unstable. For example, instead of the first turn-off time (t ₁ 1), the fixed value k2, the previous turn signal lamp signal 53 flashing last off time during operation (t 1 _0), or may be used an average value of the off time during flashing operation the last direction indicator lamp signal 53.

For the third and subsequent turn-off times, the first turn-off time (t ₁ 1) is not used for calculating the average value, for example, a fixed value k2 and the previous turn signal lamp signal 53 is blinking. The average value of the extinguishing time may be calculated by substituting the last extinguishing time (t ₁₀ ) or the average value of the extinguishing time during the previous blinking operation of the direction indicator lamp signal 53. Incidentally, instead of the first off time (t 1 _1), the average value in the case of using the last off time flashing operation when the previous direction indicator lamp signal 53 (t 1 ₀₎ is the following Become.

t _b 6 = (t ₁ 0 + t ₁ 2 + t ₁ 3 + t ₁ 4 + t ₁ 5 + t ₁ 6 + t ₁ 7) / 7

  As described above, according to the second embodiment, when the blinking operation of the direction indicator is completed while the lights are turned off, the turn-off time is longer than the calculated turn-off time average value. When it is longer than the average value of the turn-off time that has been performed for a predetermined time or more, it is determined that the blinking operation of the direction indicator has been completed, and the side illumination lamp can be quickly turned off. In addition, each turn-off time during blinking operation of the direction indicator varies depending on the ambient temperature and component characteristics. Therefore, taking the average value of the turn-off time improves the accuracy of the completion timing of blinking operation of the direction indicator. Can be made. This eliminates the need to set a long off-delay time for the side illumination lamp. Therefore, the side illumination lamp can be turned off smoothly after the lamp of the direction indicator completes blinking without being affected by the vehicle type or the vehicle environment, and the off-delay time can be shortened.

  The present invention may also be a third embodiment that combines the first embodiment and the second embodiment. In this case, the storage means for storing the measurement time measured by the measurement means stores the first storage means for storing the lighting time during the blinking time of the direction indicator and the extinguishing time during the blinking time of the direction indicator. Second lighting means, and when the lighting time immediately before the blinking time is measured, it is compared with the lighting time stored in the first memory means, while the lighting time immediately before the blinking time is measured. In this case, the side illumination lamp system has a determination unit that determines whether or not the operation of the direction indicator is stopped in comparison with the turn-off time stored in the second storage unit.

  In that case, the determination means calculates an average turn-off time value from a plurality of turn-off times stored in the second storage means, and when the previous turn-off time measured by the measurement means is longer than the turn-off time average value by a predetermined time or more. The operation of the direction indicator may be determined to have stopped.

  The determining means calculates the lighting time average value from the plurality of lighting times stored in the first storage means, and when the lighting time immediately before measured by the measuring means is shorter than the lighting time average value by a predetermined time or less, It may be determined that the operation of the direction indicator has stopped.

  In addition, the determination unit is configured such that when the lighting time measured by the measuring unit is longer than the first fixed value, or when the turn-off time measured by the measuring unit is shorter than the second fixed value, It may be determined that the operation has stopped.

  Further, the determination means is provided when a predetermined number or more of lighting times measured by the measurement means are stored in the first storage means under the condition of the lighting time among the blinking times of the direction indicator measured by the measurement means. Calculates the average value of the lighting time stored in the first storage means, compares the lighting time measured immediately before by the measuring means with the average value of the lighting time, and the lighting time measured by the measuring means is a predetermined number If not stored in the first storage means, the measurement time measured immediately before by the measurement means is compared with the first fixed value to determine whether or not the operation of the direction indicator has stopped. May be. In addition, the determination means is configured in the case where the turn-off time measured by the measurement means is stored in the second storage means for a predetermined number or more under the condition that the turn-off time of the turn indicator measured by the measurement means is the turn-off time. Calculates the average value of the extinguishing time stored in the second storage means, compares the extinguishing time measured immediately before by the measuring means with the average value of the extinguishing time, and calculates the predetermined extinction time measured by the measuring means. If not stored in the second storage means, the measurement time measured immediately before by the measurement means is compared with the second fixed value to determine whether the operation of the direction indicator has stopped. May be.

  Since a specific example of the third embodiment according to the present invention is a combination of the first embodiment and the second embodiment according to the present invention, a description thereof will be omitted. Incidentally, by combining the first embodiment and the second embodiment according to the present invention, the direction indicator 13 can be turned on or off at any timing of the lighting time or the light-off time. The off-delay time of the side illumination lamp 20 with respect to 13 can be shortened.

  Thus, according to this embodiment, whether or not the blinking operation of the direction indicator is completed according to the measurement time obtained by measuring at least one of the lighting time and the extinguishing time among the blinking time of the direction indicator. Judgment can be made. And when it is judged that the blinking operation of the direction indicator is completed, the side illumination lamp is turned off immediately, so that the side illumination lamp can be smoothly turned off after the lighting of the direction indicator completes blinking. Can do. In addition, since the blinking time of the direction indicator is measured to determine the blinking operation status of the direction indicator, it is smooth after the lighting of the direction indicator completes blinking without being affected by the vehicle type or vehicle environment. Since the side illumination lamp can be turned off, the off-delay time of the side illumination lamp can be shortened. Further, the blinking pulse signal of the direction indicator necessary for measuring the blinking time of the direction indicator is a signal wired to the direction indicator without passing a new wiring for obtaining the direction indicator signal through the vehicle body. Since it is only necessary to branch the line and connect it to the side illumination lamp system of the present invention, even when the side illumination lamp is retrofitted, the work becomes easy and the labor paid by the user can be reduced. Thus, the willingness to wear can be improved.

  Furthermore, since the means for obtaining the direction indicator signal has a different electrical connection configuration for each vehicle type, it is necessary to prepare a plurality of side illumination lamp connection systems with various specifications. By using the side illumination lamp system of the present invention, it is possible to use only one specification, so that the manufacturing cost and management cost can be reduced in the production of the side illumination lamp. As a result, the user's willingness to attach to the side illuminating lamp is improved, and the penetration rate of the side illuminating lamp is improved, thereby increasing the safety of the vehicle and greatly contributing to accident prevention. .

  According to the first, second, and third embodiments described above, the direction indicator blinks according to the measurement time obtained by measuring at least one of the lighting time and the extinguishing time among the blinking times of the direction indicator. By judging whether or not the operation has been completed, it is possible to set the timing of turning off the side illumination lamp with respect to the completion timing of the blinking operation of the direction indicator without passing a new wiring for acquiring the signal of the direction indicator through the vehicle body. There can be provided a side illumination system that does not cause a great delay and does not give the user a sense of incongruity.

  The preferred embodiments of the present invention have been described above. However, the present invention can be variously modified and changed without departing from the concept of the claims.
