Description

  The present invention relates to a lighting device for a vehicle, in particular, a light emitting unit that is attached to a vehicle such as a bicycle and emits light by irradiating the surroundings with power supplied from a power source unit, and controls that supply power from the power source unit to the light emitting unit. The present invention relates to a vehicular illumination device including a control unit that is performed according to the above.

  As a conventional vehicular lighting device, one that switches the irradiation direction of a light emitting unit based on an output from a travel detection unit is known (for example, see Patent Document 1). Specifically, the amount of vehicle rotation is detected by a dynamo (generator), etc., and when it is detected that the vehicle is traveling at a high speed (strong driving detection), it is irradiated toward the far side and the vehicle is traveling at a slower speed. When it was detected (weak running detection), it was radiating toward the front.

  In some cases, a vibration sensor is used as the travel detection unit, and the light emission control of the light emitting unit is performed based on outputs from the travel detection unit and the light / darkness detection unit (see, for example, Patent Document 2 or Patent Document 3). Specifically, when the vehicle is detected by a vibration sensor, it is detected that the surroundings are dark (dark detection) and when the driving is detected, and the light is emitted. It was turned off when it was detected that the vehicle was in the state (no-run detection).

  In the vehicular lighting device described in Patent Document 1, since the dynamo detects the amount of rotation of the vehicle wheels, there is almost no error in detecting the running, but the dynamo is large and difficult to arrange. is there. For example, when a dynamo is placed on the vehicle body, wiring to transmit power and signals from the dynamo to the vehicle lighting device is required, which is difficult when a user purchases the vehicle lighting device and installs it on his / her vehicle. It is. If the dynamo is integrated with the vehicle lighting device, a rotating connection between the dynamo's rotating part and the vehicle wheel is required, and this also allows the user to purchase the vehicle lighting device and install it on his vehicle. When it is difficult. Furthermore, the cost of dynamo is very difficult due to its complicated structure.

  Further, in the vehicle lighting device described in Patent Document 2 or Patent Document 3, since it is not necessary to detect the rotation of the wheels of the vehicle because the vibration of the vehicle is detected by the vibration sensor and the traveling is detected, the above-described installation is performed. However, it is not difficult, and the structure is simple and the cost can be easily reduced. However, the accuracy of the traveling detection is not sufficient. For example, when traveling on a very flat road surface, it may be erroneously determined as no-run detection and the light may turn off, but it may be erroneously determined to be traveling due to vibration caused by wind or bicycle parking equipment while parking. There is also a possibility of doing. Since it is very dangerous if the lights are turned off during night driving, the sensitivity of the vibration sensor must be increased to determine that even minute vibrations are driving and light should be emitted. Due to the shaking, it is erroneously determined that the vehicle is running and emits light, so that the battery is consumed rapidly and the battery life is shortened. In addition, the switch can be operated and switched every time the bicycle is parked or the vehicle starts so as not to emit light during parking, but the user's hand is extremely troublesome.

  SUMMARY OF THE INVENTION In order to solve the above-described conventional problems, an object of the present invention is to provide a vehicular illumination device that is easy to install on a vehicle and that can perform a light emission control by determining a traveling state with low cost and high accuracy. And

The vehicle lighting device of the present invention in order to achieve the object is mounted on a vehicle such as a bicycle, a light emitting unit for irradiating the surroundings emit light by the supply of power from the power supply unit, the vibration of the vehicle, acceleration, Based on a signal obtained by detecting at least one of a position or a frequency of a periodic signal that changes depending on the running state of the vehicle , at least a no-running state that is a stopped state, a predetermined speed or more Based on a signal from the travel detection unit, and a travel detection unit that detects a strong travel state in which the vehicle travels at a low speed and a weak travel state in which the vehicle travels at a speed slower than the predetermined speed. a control unit for controlling the power that will be supplied to the parts, and the scan detection when the light emitting unit is turned off repeats the detection, if the detection result is no traveling state or a weak traveling state The control unit maintains the light emitting unit in the off state, and when the detection result is a strong running state, the control unit sets the light emitting unit to the light emitting state, and when the light emitting unit is in the light emitting state, The travel detection unit repeats the detection, and when the detection result is a weak travel state or a strong travel state, the control unit maintains the light emission state of the light emitting unit, and when the detection result is a no travel state, the control The unit determines whether or not the non-running state continues for a predetermined time, and maintains the light emitting state of the light emitting unit when it does not continue, and turns off the light emitting unit when continuing It is a thing.

  By using the control unit of the present invention, it is possible to realize a vehicular illumination device that can be easily installed on the user's own bicycle and that has high traveling detection accuracy.

  In addition, by configuring the light / darkness detection unit, the travel detection unit, and the timekeeping unit as in the present invention, it is possible to make a highly accurate travel determination suitable for the boarding scene.

  In addition, by detecting the attenuation or reflected light of transmitted light due to vehicle spokes, it is possible to realize a vehicular illumination device that can be easily installed on the user's bicycle by the user and that has higher traveling detection accuracy.

  According to the present invention, three or more types of traveling speeds are detected by detecting at least one of vehicle vibration, acceleration, position, and frequency (for example, detection of strong driving, weak driving detection, and no driving detection). By configuring the control unit to operate according to the detection output of the travel detection unit, it is possible to easily install without the need for wiring or contact adjustment at the time of installation. Can be obtained. As high-precision driving detection, if light emission starts with strong driving detection and light emission continues with weak driving detection, light emission starts with a large vibration at the start of boarding, and light emission continues even with a small vibration, such as when driving on a flat road. After the bicycle is parked, it will turn off if there is no vibration and light emission will not start with small vibrations such as wind. When traveling on a very flat road surface, it will not be in a dangerous state where it is erroneously determined as no-travel detection and turned off. On the other hand, it is possible to obtain a vehicle lighting device that does not shorten the battery life by consuming a wasteful energy by misjudging that the vehicle is running due to vibrations caused by wind during parking or shaking of parking facilities. .

(Embodiment 1)
FIG. 1 is a block diagram of a vehicular illumination device according to Embodiment 1 of the present invention. In FIG. 1, a fixing unit 1 holds each component and fixes a vehicle lighting device to a vehicle or the like. The power supply unit 2 supplies power to each unit. The travel detection unit 3 detects the acceleration of the vehicle with an acceleration sensor and detects the travel by a signal corresponding to the degree of acceleration or the frequency of the acceleration (strong travel detection, strong travel detection for detecting that the vehicle is traveling at a predetermined speed or more) Detection of weak running detected at a speed slower than the speed detected by the vehicle, and no running detection detecting that the vehicle is stopped), and the determination result is output to the control unit 4. Further, the travel detection unit 3 may be constituted by a vibration sensor, a positioning sensor, or the like. In that case, the travel detection determination is performed based on the vibration, the position change, or a signal corresponding to these frequencies, and the determination result is sent to the control unit 4. Output to. The control unit 4 controls the power supplied to the light emitting unit 5 based on the signal from the travel detection unit 3.

  In the case where the travel detection unit 3 is a vibration sensor, for example, the output is read 8 times and if 8 to 5 times “vibration” is detected, strong travel detection is performed. If 4 to 3 times “vibration” is detected, weak travel detection is performed. If the number of times is “vibration”, it is determined that no running has been detected. In the case of an acceleration sensor, if the output is 1.5 gal or more, it is determined that strong running is detected, if it is 0.5 gal or more and less than 1.5 gal, weak running is detected, and if it is less than 0.5 gal, it is determined that no running is detected. . In the case of a positioning sensor, a change in position is measured every second. If the displacement distance is 0.5 m or more, strong running detection is detected. If the displacement distance is 0.1 m or more and less than 0.5 m, weak running detection is detected. If there is, it is determined as no-running detection. In the case of frequency, when the peak frequency of the output signal of the vibration sensor or acceleration sensor is 10 Hz or more, strong running detection is detected. When the frequency is more than 10 Hz and less than 10 Hz, weak running detection is detected. However, these numerical values are merely examples, and the actual judgment level may be different from these numerical values.

FIG. 2 is a flowchart showing the operation of the vehicular illumination apparatus according to the first embodiment of the present invention. The operation when the acceleration sensor according to the first embodiment is used will be described with reference to FIG. Travel detection A is performed in a light-off state, and travel detection A is repeated if no travel detection or weak travel detection is detected. As a result, even if the vehicle is parked, light is not emitted even if a weak acceleration caused by wind or bicycle parking equipment is applied to the vehicle, and wasteful energy consumption of the power supply unit such as a battery is prevented. When it is determined that the strong running is detected in the running detection A, the light emitting unit emits light. As a result, it is determined that strong running is detected with strong acceleration due to unlocking at the start of running, stand release, or shaking at the start of rowing, and the light emitting unit automatically starts to emit light. When the light emitting unit is in a light emitting state, travel detection B is performed. If strong travel detection or weak travel detection is detected, travel detection B is repeated and the light emission state is continued. As a result, if it is detected that the vehicle is running more than weakly detected, it will continue to emit light, and it will continue to emit light even if it is traveling on a flat road with little shaking. If it is determined in the running detection B that no running is detected, the light emitting unit is turned off. As a result, the light emitting unit is automatically turned off when there is no acceleration after parking. After the lights are turned off, the process returns to the travel detection A again.

(Embodiment 2)
FIG. 3 is a block diagram of the vehicular illumination apparatus according to the second embodiment of the present invention. In FIG. 3, the light / dark detection unit 6 is supplied with power from the power supply unit 2, and according to the degree of external (ambient) brightness, the brightness is detected when the brightness is higher than a predetermined value, and the ambient brightness is lower than the predetermined value. Performs dark detection and outputs the signal to the control unit 4. The control unit 4 includes a timer 7 inside, and supplies power to the light-emitting unit 5 based on a signal from the travel detector 3, a signal from the light / dark detector 6, and a timing result from the timer 7. Control. The control unit 4 can set or change the time constant of the time measuring unit 7, the travel determination constant of the travel detection unit 3, the light / dark determination constant of the light / dark detection unit 6, and the like based on the signal from the input unit 8. The other components are the same as the components in FIG.

  FIG. 4 is a flowchart showing the operation of the vehicular illumination apparatus according to the second embodiment of the present invention. The operation when the vibration sensor according to the second embodiment is used will be described with reference to FIG. Light / darkness detection C is performed in the off state, and light / darkness detection C is repeated until darkness detection is performed. As a result, even during the daytime when the vehicle is on and running, the light remains off and energy consumption such as batteries due to unnecessary light emission is prevented. Running detection E is performed until 1 second has passed after the change from light detection to dark detection, and the light emitting unit emits light when strong running detection or weak running detection is detected. If the no-run detection is confirmed, the process returns to the light / dark detection C. This makes it possible to detect weak driving with weak vibrations and to automatically emit light immediately when light enters a place where the road surface is flat even when driving in a light-off state, that is, in a bright place during the daytime. Because it is safe.

  Running detection C is performed after a lapse of 1 second from the change of light detection to dark detection, and the light emitting unit emits light when strong running detection is detected. As a result, strong driving is detected by strong vibration caused by unlocking at the start of driving, stand release, or shaking at the start of rowing, and the light emitting unit automatically starts to emit light. If weak running detection or no running detection is detected in the running detection C, the process returns to the light / dark detection C. As a result, no light is emitted during parking, even if weak vibrations caused by wind or parking facilities are applied to the vehicle, and wasteful energy consumption of the power supply unit such as a battery is prevented. The determination time (1 second) after the change from the light detection to the dark detection, which is a branch determination to the travel detection E and the travel detection C, varies depending on the travel detection signal until the travel detection is determined. In other words, if the vibration sensor output is “vibration” 3 times out of 8 times, weak running is detected, but if “vibration” is detected even once before the detection of this running detection, the light detection to dark detection is detected. The determination time after the change is extended to 15 seconds. In this way, when entering a flat road surface that suddenly becomes dark such as a tunnel in the daytime, the time for light emission in weak running detection is sufficiently long, 15 seconds after changing from light detection to dark detection, so it is reliable. Can emit light. On the other hand, during parking at dusk, the time when there is a risk of light detection and light emission due to wind or shaking of the bicycle parking facilities can be made within a short time of 1 second. Can prevent energy consumption.

After light emission, light / dark detection F is performed, and when the light detection continues for 5 seconds or more, the light emitting unit is turned off. If the light detection is less than 5 seconds, the process returns to the light / dark detection F to continue the light emission state. When darkness is detected, travel detection F is performed. Since the light detection is not turned off until the light detection continues for 5 seconds in this way, even if the bright and dark state is alternately repeated in a short time by the illumination from the street light at night and other vehicles, the light emission and the light turn off alternately It is possible to prevent the flickering phenomenon to be replaced. If strong travel detection or weak travel detection is detected in the travel detection F, the process returns to the light / dark detection F to continue the light emission state. When the no-run detection continues for 7 seconds or more in the running detection F, the light emitting unit is turned off. When the no-run detection continues for less than 7 seconds, the process returns to the light / dark detection F and the light emission state is continued. Thus, the light emitting unit does not turn off until it lasts for 7 seconds, so even if it is detected that there is no running temporarily while running on a flat road, the light emitting unit continues to emit light if weak running is detected within 7 seconds. Therefore, it is possible to prevent a dangerous state in which the lights are turned off during traveling.

  After the light emitting unit is turned off, the light / dark detection D is repeated until 60 seconds or more have elapsed, and the light / dark detection D is repeated unless dark detection is performed. If the darkness is detected within 60 seconds after the light is turned off, the traveling detection D is performed, and the light emitting unit emits light when the strong traveling detection or the weak traveling detection is performed. If no running is detected within 60 seconds after the lights are turned off, the process returns to the light / dark detection D. When 60 seconds or more have passed after the light is turned off, light / dark detection C is performed.

  By doing this, if no running is detected by waiting for a signal at night or temporarily stopped and the light-emitting part is turned off, and if driving is started again within 60 seconds, light emission is started even if weak running detection is started, so that light can be reliably emitted. . On the other hand, after parking for 60 seconds or more after the lights are turned off, the light is not emitted in the weak driving detection, and erroneous light emission due to wind and vibrations from the bicycle parking equipment is prevented.

  However, these numerical values are merely examples, and the actual judgment level may be different from these numerical values.

The block diagram and the flow diagram are the same as those in FIGS. 3 and 4, and the difference is that the traveling state is detected by detecting the attenuation or reflected light of the transmitted light by the spokes of the vehicle. . In FIG. 5, the vehicle lighting device 10 is fixed to the vehicle frame 9, and the position thereof is located inside the wheel 12 and in the vicinity of the spoke 11. The travel detection unit 3 of the vehicle illumination device 10 detects the light passing through the spoke 11 part of the vehicle in the horizontal direction or the light reflected by the spoke 11 with a lens or the like, so that the illuminance depends on the position of the spoke 11. Changes. Since this illuminance change is a cyclical change between light and dark periodically during travel, it is determined that strong travel is detected when the repetition period is early, weak travel is detected when slow, and no travel is detected when there is no change. Further, by performing light / dark determination with the average value of the illuminance, it also serves as a light / dark detector, thereby reducing the number of parts and reducing the cost.

  The vehicle lighting device according to the present invention does not require wiring or contact adjustment at the time of installation, can be easily installed, can detect a highly accurate travel, and can be configured at a low cost, and therefore the vehicle lighting device, particularly its bicycle.
