Description

  The present invention relates to a lighting control device for a hazard lamp installed in an automobile, and more particularly, to a lighting control device capable of adjusting a lighting state according to preference by installing as an option.

  The automobile is equipped with a hazard lamp that keeps blinking 60 to 120 times per minute when the vehicle is temporarily stopped temporarily or temporarily. This hazard lamp blinks by pressing a hazard switch such as a push button type or other toggle switch provided around the dashboard or steering wheel in the passenger compartment. Since this hazard switch has a design specification that is less frequently used in normal operation and neglects operability during operation, the hazard switch is generally arranged at an inconvenient location.

  For the purpose of warning the danger of a rear-end collision, the hazard lamp has been established as a normal traffic rule to turn on the hazard switch and keep it blinking repeatedly for a required time. As a typical example of the rear-end collision prevention display, it is also used on a daily basis when a truck for delivery service parks for a short time on the street to deliver cargo, or when a taxi temporarily stops to get on and off passengers. The However, in general passenger cars, unless it is a vehicle failure, it is not used so often from the beginning, so the operability based on the layout of the hazard switch is less likely to be a little inconvenient. .

  However, in today's automobile culture, it is well established to operate hazard lamps only for a short time of about a few seconds for some kind of signal to a passing car, for example, “Indication of thank you for giving me the path”. In such a use, since it is a daily thing, operability during driving cannot be neglected.

Therefore, a structure is known in which a hazard switch is attached to a steering wheel that is easily reachable from the driver. In other words, by disposing the button of the hazard switch in a part of the airbag housing part in the center of the steering wheel or in the vicinity thereof, the hazard lamp can be blinked with the same feeling as that of blowing a horn (horn). There was what was made possible (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-115622 (paragraphs 0005 to 0008, FIG. 1)

  However, the hazard switch is constituted by a toggle switch, and after the ON operation is performed once, the ON state is continued until the OFF operation is performed. Therefore, the OFF operation must be executed after the ON operation. Therefore, even if the monitor lamp on the panel indicates that the hazard lamp is blinking, it is indispensable to turn it off when it is no longer necessary to turn it on. Therefore, if the turn-off operation is automatic, it will never be over.

  In addition, if the hazard lamp blinks for “thank you”, the burden on the driver is reduced because only one operation is required to blink for only a few seconds and then automatically turn off at an appropriate timing. Being reduced and kind.

Therefore, in the present invention, if the above-mentioned problem is solved and a switch arranged close to the driver is turned on with a light operation, the hazard lamp blinks according to the time set in advance in the timer and then automatically turns off. It is an object of the present invention to provide a hazard timer that can be used.
Further, lighting is controlled by several types of operations such as “instantaneous touch”, “long press”, “instant touch after long press”, or “pressing for a long time to be actuated (press for a while)”. That is, it is also an object to be able to adjust the ON-OFF timing according to the time until touching (pressing) and releasing, the number of times of touching (pressing), a combination pattern thereof, and the like.

  In order to solve the above problems, the invention according to claim 1 is directed to a toggle switch (SW21) that keeps the hazard lamp (24) blinking in response to an ON operation, and always according to an ON output of the toggle switch (SW21). A hazard timer (30) connected to a lighting control unit (20) having an intermittent means (23) for supplying intermittent current from a power source (AL12) to a hazard lamp (24) and adding a timer function; A touch sensor (11) that senses a predetermined operation; and a timer (10) that is turned off when a set time (T) elapses after the touch sensor (11) senses a predetermined operation and is turned on. The hazard timer (3), wherein the timer (10) and the toggle switch (SW21) are connected to input the OR output to the intermittent means (23). ) It is.

  According to the invention which concerns on Claim 1, there exist the following effects. First, when the operator turns on the toggle switch (SW21), intermittent current is supplied from the constant power supply (AL12) to the hazard lamp (24) and continues to blink. Since this toggle switch (SW21) continues the condition branched by the most recent past operation, after the ON operation is performed once, the ON state is continued until the OFF operation is performed. On the contrary, after the OFF operation is performed once, the OFF state is continued until the ON operation is performed. Therefore, if the operator turns on the toggle switch (SW21) once, the hazard lamp (24) continues to blink until it is turned off next time.

  On the other hand, even if the touch sensor (11) that senses a predetermined operation is touched once and the output is turned ON, the timer (10) is turned OFF when the set time (T) elapses after the ON output. The timer (10) and the toggle switch (SW21) are connected to input their OR outputs to the intermittent means (23) if either one is ON.

  When the OR outputs of the toggle switch (SW21) and the timer (10) are input to the intermittent means (23), the intermittent current is constantly supplied from the power source (AL12) to the hazard lamp (24) and continues to blink. As a result, if any one of the touch sensor (11) and the toggle switch (SW21) is ON, the hazard lamp (24) blinks ON.

  When the operator touches the touch sensor (11) once with the toggle switch (SW21) turned off, the hazard lamp (24) blinks after the touch sensor (11) is turned on and the set time (T ) Is turned off after elapse. Therefore, if the operator touches the touch sensor (11) only once, the hazard lamp (24) can be blinked and automatically turned off for a short set time (T) as generally desired.

  When the toggle switch (SW21) is turned on, the hazard lamp (24) continues to blink, but this conditional branch is more effective than others, so at this time the outputs of the touch sensor (11) and timer (10) No matter which is ON-OFF, it becomes meaningless and the hazard lamp (24) continues to blink.

  According to a second aspect of the present invention, in addition to the first aspect of the present invention, the time (t) when the continuation of the touch operation is recognized by the touch sensor (11) capable of identifying the start and end of the touch is short and long Alternatively, the hazard timer (30) is characterized in that the timing at which the timer (10) is turned ON and / or the set time (T) is controlled in accordance with a repeated touch pattern.

  According to the second aspect of the present invention, when the touch sensor (11) identifies the start and end of the touch, the length of time (t) during which the touch operation is continued can be measured, and the touch can be repeated. The repeated touch pattern can be recognized by patterning the interval between the previous touch and the subsequent touch, and the length of the touch time (t) before and after each touch.

  That is, the timing at which the timer (10) is turned on and off is adjusted depending on the time until the touch sensor (11) is touched (pressed) and how many times it is touched (pressed). By doing so, for example, “instantaneous touch”, “long press”, “instant touch after long press”, or “pressing for a time just to actuate (press for a while)” can be performed in several types, and the lighting control changes Can be attached.

  The invention according to claim 3 is characterized in that, in addition to the invention according to claim 1 or 2, the touch sensor (11) is disposed in the operation part of the parking brake (29) or in the vicinity of the operation part. A hazard timer (30).

  According to the invention of claim 3, if the parking brake (29) is operated, the touch sensor (11) disposed in the vicinity of the operating part of the parking brake (29) or in the vicinity of the operating part is inevitably touched. Since the hazard lamp (24) blinks for the set time (T) of the timer (10) without requiring the consciousness or attention of the person, ensuring safety and other signals are easy.

  In particular, in the case of an arrangement where the operability of the existing hazard switch (toggle switch (SW21)) is neglected depending on the vehicle type, it is easy to turn off the hazard lamp (24) during operation, so it is easy to neglect safety. In that respect, the touch sensor (11) disposed in the operation part of the parking brake (29) or in the vicinity of the operation part is within the reach of the driving driver, so that the operability is good, ensuring safety, etc. It is easy to sign.

  The invention according to claim 4 is a hazard timer (30) characterized in that, in addition to the invention according to any one of claims 1 to 3, a push switch is used as the touch sensor (11). is there.

  According to the invention which concerns on Claim 4, it is a hazard timer (30) using a push switch as a touch sensor (11), and since it can abbreviate | omit the electronic circuit for comprising a touch sensor (11), it is simple In addition, the cost can be reduced by reducing the cost.

  According to a fifth aspect of the present invention, in addition to the first aspect of the present invention, when the predetermined operation is completed after being turned on at the start of the predetermined operation and continuing arbitrarily. A hazard timer (30) comprising the timer (10) having a function of turning off when a set time (T) elapses after starting.

  According to the fifth aspect of the present invention, the timer (10) is activated and set after the predetermined operation is continuously turned on from the start of the predetermined operation to the end by “pressing for a time to be actuated (pressing for a while)”. Turns OFF when time (T) has elapsed. Therefore, since the arbitrary length which touched the touch sensor (11) is extended a little and the hazard lamp (24) blinks, safety is ensured and other signals are easy.

  According to a sixth aspect of the present invention, in addition to the first aspect of the present invention, the timer (10) is started using the ON output of the parking brake operation indicator lamp (25) as a trigger. A hazard timer (30) characterized in that

  According to the sixth aspect of the present invention, when the parking brake is operated, whether it is a side lever (manual) type or a foot pedal (stepping) type, the parking brake operation indicator lamp (25) such as a panel is lit in red. After the timer (10) is activated and turned on, the hazard lamp (24) blinks for a set time (T) and then automatically turns off. In particular, in a vehicle type equipped with a foot pedal type parking brake, it is possible to blink the hazard lamp (24) in conjunction with the parking brake without depending on the touch sensor (11).

  According to the first aspect of the present invention, the operator simply touches the touch sensor (11) once and automatically blinks the hazard lamp (24) for a short set time (T) as desired. Since it can be turned off, convenience is enhanced.

  According to the second aspect of the present invention, for example, “touch for a moment”, “long press”, “long press”, “depending on the time until the touch sensor (11) is touched (pressed) and how many times it is touched (pressed)”. The operation can be differentiated into several types, such as “touch for a moment after long press” or “press as long as you want to activate (press for a while)”, and change the lighting control.

  According to the third aspect of the present invention, the touch sensor (11) disposed in the operation part of the parking brake (29) or in the vicinity of the operation part is operated with respect to the lighting operation of the hazard lamp (24). It is easy to ensure safety and other cues.

  According to the invention which concerns on Claim 4, since the electronic circuit for comprising a touch sensor (11) can be abbreviate | omitted, it can be made simple and cheap and cost can be reduced.

  According to the invention which concerns on Claim 5, since arbitrary length which touched the touch sensor (11) is extended a little and the hazard lamp (24) blinks, ensuring safety and other signals are easy.

  According to the invention of claim 6, in a vehicle type equipped with a foot pedal type parking brake, the hazard lamp (24) blinks in conjunction with the parking brake without depending on the touch sensor (11). Is possible.

  Next, the configuration and operation of the embodiment of the present invention will be described in detail with reference to the drawings as appropriate. FIG. 1 is a block diagram illustrating wiring in which a hazard timer according to the embodiment is optionally connected to an existing lighting control unit.

  As shown in FIG. 1, the hazard timer 30 of the present invention is configured to be optionally connected to an existing lighting control unit 20 in a vehicle to exhibit its function.

  The lighting control unit 20 includes a toggle switch SW21, a connect box 22, and intermittent means (flash relay block) 23, and controls the lighting of the hazard lamp 24. The hazard lamp 24 is generally used also as a direction indicator lamp (hereinafter abbreviated as “blinker”), and is often used by distinguishing the lighting form under the control of the lighting control unit 20.

  Specifically, out of the orange signal lights that are arranged at the four corners of the vehicle, a total of four lamps, if either one of the right and left lights blinks, it becomes a blinker application, and all four lights at these four corners blink at the same cycle. This is what is called a hazard lamp 24.

  The intermittent means 23 is an electromagnetic relay or a semiconductor circuit for intermittently turning on and off the lighting current in order to continue blinking 60 to 120 times per minute, and the intermittent means 23 may also be used as a winker. Many. In addition, regarding the use of the blinker of these signal lights, the description is omitted because it is not essential for the description of the present invention.

  Note that the toggle switch SW21 in claim 1 is a general term for conditional branch switches having the property of switching and maintaining conditions from ON to OFF or from OFF to ON each time one operation is performed. In particular, the switch lever that reverses the rotation angle and branches conditionally is not limited to a narrowly-defined toggle switch that specifies the shape of the switch lever. Including push switches, slide switches, and seesaw switches. In other words, it means existing hazard switches that are used in most types of general vehicles.

  Also, a connect box 22 for relaying the wiring from the toggle switch SW21, an intermittent means 23 to which the ON-OFF control line 21a from the toggle switch SW21 and the constant power supply AL12 are connected via the connect box 22, The circuit is configured such that the continuous power supply AL12 is intermittently connected to the hazard lamp 24 by the continuous opening / closing operation of the intermittent means 23.

Hazard timer 30 is constituted by a timer 10 for driving is connected to a constant power AL12, by the touch sensor (push switch) 11 that is connected to the timer input 10 _in. The hazard timer 30 is connected to the lighting control unit 20 via the control line 13 by the timer output unit 10 _out . The timer input unit 10 _in is also connected with a lighting signal or a lighting power source of the parking brake operation display lamp 25.

  The hazard timer 30 is connected to the existing lighting control unit 20 in the vehicle only by connecting the control line 13 to any of the connection points 22a and 22b in the connection box 22 included in the lighting control unit 20 or before and after. The power supply AL12 is always connected as a power supply for driving the hazard timer 30 itself.

  As is well known for vehicular electrical wiring, a positive voltage of an on-vehicle 12V (or 24V) battery is connected via a fuse or the like (not shown) so that a constant power supply AL12 is supplied. However, a circuit is configured by connecting a conductive portion such as a vehicle frame chassis of the vehicle to the ground wire as a ground wire.

  The touch sensor 11 senses that the capacitance specific to the electrode changes when a human finger or the like is touched, and operates an open / close switch such as a relay. An electronic circuit or the like corresponding to the capacitance change detection relay (see FIG. The touch sensor 11 may be replaced with a simple push switch. In that case, the corresponding electronic circuit or the like can be omitted, so that simplification and cost reduction can be achieved.

  On the other hand, as a more realistic design specification, the lighting voltage of the parking brake operation display lamp 25 may be cited instead of the touch sensor 11. And the timer 10 is started using the ON output of the parking brake operation display lamp 25 as a trigger. By doing so, both the side lever (manual) type and the foot pedal (stepping) type, when the parking brake is activated, the timer 10 is activated and set at the timing when the parking brake operation indicator lamp 25 on the panel, etc. is lit red. After the hazard lamp 24 blinks for the time T, it is automatically turned off. In particular, in a vehicle type equipped with a foot pedal type parking brake, it is possible to blink the hazard lamp 24 in conjunction with the parking brake without depending on the touch sensor 11. Here, it is specifically explained that “the timer (10) is started using the ON output of the parking brake operation display lamp (25) as a trigger” defined in claim 6.

  Note that the touch sensor 11 may have other configurations as long as it is a sensing unit that senses a predetermined operation as defined in claim 1. Furthermore, the touch sensor 11 according to claim 2 may have any other configuration as long as it is a sensing means that can identify the start and end of the touch and can identify the length of the touch time t and convert it into an electrical signal. .

  Preferably, the timing at which the timer 10 is turned on and / or the set time T is controlled according to the length of the time t at which the continuation of the touch operation on the touch sensor 11 is recognized or the repeated touch pattern.

  Specifically, if the touch sensor 11 identifies the start and end of the touch, it is possible to measure the length of the time t during which the touch operation is continued, and when repeatedly touching, until the previous touch and the subsequent touch The repetitive touch pattern can be recognized by patterning the interval and the lengths of the touch time t before and after.

  That is, the timing at which the timer 10 is turned on and off is adjusted depending on the time until the touch sensor 11 is touched (pressed) and how many times it is touched (pressed). By doing so, for example, “instantaneous touch”, “long press”, “instant touch after long press”, or “pressing for a time just to actuate (press for a while)” can be performed in several types, and the lighting control changes Can be attached.

  In FIG. 1, the touch sensor 11 is indicated by a push switch symbol. The push switch closes the electrical contact by a pressing force against the biasing of the spring, and when the pressing force is lost, the push switch operates as an open / close switch that opens the electrical contact by the biasing of the spring. Hereinafter, for convenience of explanation, the touch sensor 11 and the push switch 11 may be read in the same meaning. In FIG. 1, the push switch 11 and the timer 10 are shown separated from each other so that they can be arranged at the optimum positions. However, the push switch 11 and the timer 10 may be integrated.

FIG. 2 is a time chart of the hazard timer according to the embodiment, where (a) is a touch sensor OFF, (b) is a timer output OFF, (c) is a lighting state of a hazard lamp, and (d) is ON / OFF of a toggle switch. State, (e) ON output by momentary touch below threshold (threshold value) t ₁ to the touch sensor, (f) ON output of timer set time, (g) spans hazard lamp set time T blink, (h) the toggle switch OFF, (i) is oN considerable time output due to the touch threshold value t ₁ or more threshold t ₂ the following times on the touch sensor, (j) the timer oN output, separated at any time , (k) a state where the blinking time X of the hazard lamps are separated at any time, (l) is a toggle switch OFF, (m) is oN the output of the touch sensor that is time touch exceeds the threshold t _2, n) is an ON output of a timer extended by a set time T at a time corresponding to (m), (o) is a blinking time X of a hazard lamp controlled at a time corresponding to (n), and (p) is a toggle. The switch is OFF.

Here, in FIGS. 2A to 2D, if the toggle switch SW21 shown in FIG. 2D is ON, the power AL12 is always output intermittently from the intermittent output unit 23 _out and supplied to the hazard lamp 24. Thus, the hazard lamp 24 continues to blink at a cycle of 60 to 120 times (standard) per minute as shown in (c).

In FIGS. 2E to 2P, when the toggle switch SW21 shown in FIGS. 2H and 1L is OFF, as shown in FIG. 2E, the ON signal of the touch time t is sent from the push switch 11. When input to the timer input unit 10 _in , the timer 10 is turned off after outputting the ON signal of the set time T as shown in (f) according to the length of the touch time t.

Specifically, as shown in (e), the timer 10 shown in (f) when the touch sensor (push switch) 11 is 0 <t <threshold value t _1, that is, “touching momentarily” (or “cushing”). Is turned OFF after outputting the ON signal for the set time T.

As shown in (i) by another operation, the timer shown in (j) when the touch sensor (push switch) 11 is “long touch” (or “long press”) not less than the threshold value t _{1 and not} more than the threshold value t _2. 10 is turned OFF after an ON signal is output until the next “instantaneous touch”. For example, if the touch sensor 11 is “long touched” when it stops for only one minute before the convenience store, the hazard lamp 24 will start flashing. This is convenient when you “touch for a moment” and the light goes out. In this case, the timing at which the timer (10) is turned ON and / or the set time (T) according to the length of the time (t) when the continuation of the touch operation is recognized or the repeated touch pattern is set. It specifically explains what is defined as “controlled”.

  Further, as a kind of touch sensor 11, for example, when a “switch that is turned on only while being pressed and turned off when released”, as represented by a push switch or the like, is pressed for a very short time as shown in FIG. In other words, if the user presses “push”, the hazard lamp 24 blinks for the set time T as shown in FIG. On the other hand, when the push switch 11 is “long pressed”, the hazard lamp 24 blinks for an arbitrary time as shown in (k) and then automatically turns off. That is, the blinking time X is arbitrary.

As indicated by (f) with respect to (e) or (j) with respect to (i), different timings of the timer operation are formed according to the length of the pressing time of the push switch 11 and output from the timer output unit 10 _out. . At this time, the timer ON signal at the set time T is input to the operation input unit 23 _in of the intermittent means 23 via the control line 13 and output from the intermittent output unit 23 _out .

  Note that as the set time T with respect to the touch time t, various types or stepless proportional relationships, for example, a set time T that is 1 to 5 times the touch time t may be signal-formed.

When the touch ON output for a longer touch time t such that the touch sensor shown in (m) exceeds the threshold t ₂ and “presses for a while” is finished, the timer 10 is started and the ON is extended by the set time T. A signal is output and shown in (n). (O) shows a state in which the hazard lamp 24 continues to blink for a corresponding time X = t + T by the ON signal shown in (n). Here, as defined in claim 5, “the function of turning on when the predetermined operation is completed after being turned on by the start of the predetermined operation and turned off when the set time (T) has elapsed and then turned off. The timer (10) "is specifically explained.

  FIG. 3 is an actual layout diagram of the main part of the hazard timer according to the embodiment, and shows the layout of related parts in the driver's seat of the passenger car. It is easy to understand. As shown in FIG. 3, a toggle switch SW21 is disposed on the dashboard 28 at a position where the operation of the driver's right hand is barely possible, and the touch sensor 11 is located near the tip of an operation lever that is a grip portion of the parking brake 29. Optional equipment. As defined in claim 3, it is limited to “near the operation unit”, that is, on the operation lever, as “the touch sensor (11) is disposed in the operation unit of the parking brake (29) or in the vicinity of the operation unit”. It is not necessary, and it may be in the vicinity of a pedal of a foot pedal type parking brake (not shown) as long as it is “a position where it can be easily touched after operation”.

  In the actual driving situation of the vehicle, the hazard lamp 24 blinks when the driver or the like manually operates the toggle switch SW21 provided in the passenger compartment. The hazard switch constituted by the toggle switch SW21 is generally neglected in operability during operation. Specifically, it is arranged on the dashboard 28 or the like (see FIG. 3) on the back side of the steering wheel as viewed from the driver. Because it becomes.

  In most vehicle types, the parking brake 29 is used to avoid the problem of running the vehicle while the parking brake 29 is forgotten to be released and to notify the driver that the parking brake 29 is operating. An operation indicator lamp 25 is disposed on the dashboard 28.

  With the optional equipment of the hazard timer 30 according to the embodiment of the present invention, the touch sensor 11 is touched only by touching the touch sensor 11 regardless of whether the parking brake 29 is operated or not. After the hazard lamp 24 starts blinking at a frequency of ˜120 times (standard), approximately three-way lighting control can be performed. That is, as shown in FIG. 2 (g), the flashing is repeated only for the short set time T, or as the blinking time X = arbitrary time shown in (k), or the blinking time X = t + T shown in (o). . Then, the hazard lamp 24 can convey a feeling of “thank you” to a passing car with the effect of talking to a person.

In the present embodiment, for example, the setting time T may be appropriately adjusted within a range of 3 seconds to 20 seconds, or the user may be able to adjust according to preference.
The hazard timer 30 according to the present embodiment is an optional equipment on an existing automobile, but may be designed to be incorporated from the beginning as a standard equipment of an automobile.
Further, the touch sensor 11 has been described as being arranged near the tip of the operation lever of the parking brake 29, but this point may be arranged so as to be easy for the user to use.
Further, the touch sensor 11 may be replaced with various types as long as it can detect a predetermined operation.

It is a block diagram which shows the wiring which connected the hazard timer which concerns on embodiment as an option to the existing lighting control part. It is a time chart of the hazard timer concerning an embodiment. It is a principal part actual-position layout of the hazard timer which concerns on embodiment.
