Embodiment
About the illumination controller in saddle ride type vehicle involved in the present invention, enumerate suitable execution mode, be described in detail below with reference to accompanying drawing.
Fig. 1 is the block diagram of the illumination controller 10 in saddle ride type vehicle.Illumination controller 10 possesses: the control device 18 be located at the direction lamp switch (switch element) 12 of the saddle ride type vehicle of two-wheeled motorcycle etc., warning against danger lamp switch (switch element) 14, light device 16 and according to the direction lamp switch 12 of driver and the operation of warning against danger lamp switch 14, light device 16 lighted.
Light device 16 has: the indicator light LED24R that the indicating device LED24L that on the right side of the front portion being located at the described front portion of saddle ride type vehicle and the right side at rear portion of the front left LED20L being located at the described front portion of saddle ride type vehicle and the left side at rear portion of formation left direction indicator light and rear left LED22L, formation right direction indicator light, LED20R and rear right LED22R, expression left direction indicator light are lighted, expression right direction indicator light are lighted.Indicating device LED24L and 24R is arranged in the not shown instrument component that is equipped in described saddle ride type vehicle, plays function as lighting the indicator light confirmed.
Control device 18 has: pressure unit 30, interval power supply extra cell 32, control part (control unit) 34 and drive division 36L, 36R.Pressure unit 30 is connected with storage battery 38, provides such as 8 ~ 16V(volt from storage battery 38 to pressure unit 30) voltage.The voltage step-down provided is supplied to control part 34 and interval power supply extra cell 32 to assigned voltage (such as 5V) by pressure unit 30.In addition, directly voltage is provided from storage battery 38 couples of drive divisions 36L, 36R.
In addition, interval power supply extra cell 32 applies the voltage V1 of constant voltage off and on to direction indicator light switch 12 and warning against danger lamp switch 14.Such as, although not shown, but interval power supply extra cell 32 have: to the assigned voltage provided from pressure unit 30 carry out dividing potential drop bleeder circuit and to the constant voltage V1(such as 0 ~ 2V after bleeder circuit dividing potential drop) output carry out the switch of on-off.Then, by under the control of control part 34, this switch of interval power supply extra cell 32 carries out on-off action, generates pulse voltage, direction indicator light switch 12 and warning against danger lamp switch 14 is applied to the pulse voltage of the voltage V1 of this generation.In addition, if the voltage V1 applied direction indicator light switch 12 and warning against danger lamp switch 14 to be off and on set to the high voltage of 8V ~ 16V etc., be then easy to produce leakage current, but in the present embodiment, by voltage V1 is set to less voltage, the generation of leakage current can be suppressed.
At this, the waveform of the voltage that interval power supply extra cell 32 exports has the mode waveform for identifying whether to create at direction lamp switch 12 and warning against danger lamp switch 14 peculiar (intrinsic) of leakage current.
As shown in Figure 2, the waveform (distinctive mode waveform) from the output voltage of interval power supply extra cell 32 can be such as the waveform that have passed through the pulse voltage after modulation with the voltage V0 of 0V and voltage V1 alternately change, its frequency.That is, output voltage can be the voltage of the mode waveform formed with predetermined multiple different frequency modulation(FM).In the illustrated example shown in fig. 2, be duty ratio be 50%, frequency carries out with 100Hz, 50Hz, 200Hz modulating the mode waveform formed.
In addition, as shown in Figure 3, can be such as with the waveform of the voltage V0 of 0V and voltage V1 alternately change, multiple pulse voltages that duty ratio is different from the output voltage of interval power supply extra cell 32.That is, output voltage can be the voltage of the mode waveform formed with predetermined multiple different duty ratio.In the example depicted in fig. 3, be frequency-invariant, the duty ratio mode waveform that carries out changing with 50%, 25%, 75% and formed.In addition, the waveform from the output voltage of interval power supply extra cell 32 also can be with the voltage V0 of 0V and voltage V1 alternately change and its frequency have passed through the waveform of the pulse voltage after modulation, and is the waveform of multiple pulse voltages that duty ratio is different.
Frequency setting from the output voltage of interval power supply extra cell 32 is the frequency (number Hz degree) that causes higher than artificial operation (operation of the loudspeaker (siren) of described saddle ride type vehicle is located in the on-off operation of the direction lamp switch 12 that such as driver carries out or warning against danger lamp switch 14 or operation) and lower than the frequency of ring frequency (such as 380Hz ~ 440Hz) of loudspeaker being located at described saddle ride type vehicle.In addition, the waveform from the output voltage of interval power supply extra cell 32 can be only the waveform that frequency have passed through the pulse voltage after modulation, or also can be only the waveform of multiple pulse voltages that duty ratio is different.
Direction lamp switch 12 makes lighting and the switch lighting on-off of right direction indicator light of left direction indicator light, driver is when hope makes left direction indicator light light, direction lamp switch 12 is connected (switch connection of left direction indicator light) with the 1st contact 12a, when hope makes right direction indicator light light, direction lamp switch 12 is connected (switch connection of right direction indicator light) with the 2nd contact 12b.
1st contact 12a prevents with resistance 40(resistance value Rref via the overdue bright of control device 18) and ground connection, the 2nd contact 12b prevents with resistance 42(resistance value Rref via the overdue bright of control device 18) and ground connection.If direction lamp switch 12 is connected with the 1st contact 12a, then off and on the two ends of resistance 40, voltage V1 is applied to overdue bright preventing from interval power supply extra cell 32, if direction lamp switch 12 is connected with the 2nd contact 12b, then apply voltage V1 to overdue bright preventing with the two ends of resistance 42 from interval power supply extra cell 32.
Warning against danger lamp switch 14 is the switches lighting (left direction indicator light and right direction indicator light are lighted simultaneously) on-off making hazard warning light, when hazard warning light is lighted in hope, warning against danger lamp switch 14 is connected (warning against danger lamp switch 14 is connected) with the 3rd contact 14a.3rd contact 14a brightly to prevent with resistance 40,42 and ground connection via overdue respectively.If warning against danger lamp switch 14 becomes connection, then apply voltage V1 to overdue bright preventing with the two ends of resistance 40,42 off and on from interval power supply extra cell 32.Overduely brightly voltage VL, VR with the two ends of resistance 40,42 produce is prevented to be input in control part 34 via holding wire 46,48 at this.
Owing to applying voltage V1 to direction lamp switch 12 off and on from interval power supply extra cell 32, therefore when direction lamp switch 12 disconnects (during the state that the 1st contact 12a and the 2nd contact are not all connected), when producing leakage current in the reason owing to being attached with moisture etc. at direction lamp switch 12 (electric leakage resistance Rm is such as 1k Ω), apply voltage V2(V2=Rref × V1/(Rm+Rref to overdue bright preventing with the two ends of resistance 40,42 off and on from direction lamp switch 12)).That is, to overdue bright prevent with resistance 40,42 apply with voltage V0 and voltage V2 hocket change voltage.
In addition, owing to applying voltage V1 to warning against danger lamp switch 24 off and on from interval power supply extra cell 32, therefore, when warning against danger lamp switch 14 disconnects, when producing leakage current in the reason owing to being attached with moisture etc. at warning against danger lamp switch 14 (electric leakage resistance Rm is such as 1k Ω), apply voltage V2(V2=Rref × V1/(Rm+Rref to overdue bright preventing with the two ends of resistance 40,42 off and on from warning against danger lamp switch 14)).That is, to overdue bright prevent with resistance 40,42 apply with voltage V0 and voltage V2 hocket change voltage.If resistance value Rref is such as 100 Ω, then voltage V2 becomes (100/1100) V1 ≒ 0.09V1, becomes the value being less than voltage V1.
Control part 34, based on overdue bright voltage VL, VR preventing the two ends using resistance 40,42 of the input via holding wire 46,48, differentiates the on off state of direction lamp switch 12 and warning against danger lamp switch 14.In detail, control part 34 is applying the timing of voltage V1 to direction indicator light switch 12, the overdue bright voltage VL at the two ends with resistance 40 that prevents becomes threshold value Vt(V2<Vt<V1) more than when, be judged as that direction lamp switch 12 is connected (switch connection of left direction indicator light) with the 1st contact 12a, when overdue bright prevent from becoming more than threshold value Vt with the voltage VR at the two ends of resistance 42, be judged as that direction lamp switch 12 is connected (right direction indicator light switch is connected) with the 2nd contact 12b.In addition, control part 34 is applying the timing of voltage V1 to warning against danger lamp switch 14, overdue bright when preventing from all becoming more than threshold value Vt with voltage VL, the VR at the two ends of resistance 40,42, is judged as that warning against danger lamp switch 14 is connected.
On the other hand, control part 34 is applying the timing of voltage V1 to direction indicator light switch 12 and warning against danger lamp switch 14, overdue bright when to prevent with voltage VL, the VR at the two ends of resistance 40,42 all lower than threshold value, be judged as that the switch of left direction indicator light and right direction indicator light disconnects (direction lamp switch 12 not with the 1st contact 12a and any one state be connected of the 2nd contact 2b), warning against danger lamp switch 14 disconnects.Thus, even if when direction lamp switch 12 and warning against danger lamp switch 14 produce leakage current, can not be judged as that direction lamp switch 12 is connected with the 1st contact 12a or the 2nd contact 12b, also can not be judged as that warning against danger lamp switch 14 is connected.
At this, due to the voltage V1 by reducing interval power supply extra cell 32 pairs of direction indicator light switch 12 and warning against danger lamp switch 14 applying, noise component(s) will be made to become large, thus S/N is than reducing, therefore, consider due to the impact of noise (noise produced by the periphery of the illumination controller 10 of the ring of aforementioned loudspeaker etc.) and make the overdue bright situation preventing from becoming with voltage VL, the VR at the two ends of resistance 40,42 more than threshold value Vt.Even if in this case, the voltage applied due to interval power supply extra cell 32 pairs of direction indicator light switch 12 and warning against danger lamp switch 14 has distinctive mode waveform, therefore, can prevent the erroneous judgement due to the impact of noise from being that direction lamp switch 12 is connected with the 1st contact 12a or the 2nd contact 12b, or erroneous judgement is that warning against danger lamp switch 14 becomes connection.
If be simply described, control part 34 only when the voltage that the interval power supply extra cell 32 pairs of direction indicator light switch 12 apply mode waveform, with when the mode waveform of the overdue bright voltage VL preventing the two ends of use resistance 40 from producing is consistent, be just judged as that direction lamp switch 12 is connected with the 1st contact 12a.Control part 34 only when the voltage that the interval power supply extra cell 32 pairs of direction indicator light switch 12 apply mode waveform, with when the mode waveform of the overdue bright voltage VR preventing the two ends of use resistance 42 from producing is consistent, be just judged as that direction lamp switch 12 is connected with the 2nd contact 12b.In addition, control part 34 only when the voltage that the interval power supply extra cell 32 pairs of direction indicator light switch 12 apply mode waveform, with when overdue bright voltage VL, VR preventing the two ends of use resistance 40,42 from producing is consistent, be just judged as that warning against danger lamp switch 14 becomes connection.
Drive division 36L is used for front left LED20L, rear left LED22L and indicating device LED24L are lighted, control part 34, when being judged as that direction lamp switch 12 is connected with the 1st contact 12a, controlling drive division 36L and front left LED20L, rear left LED22L and indicating device LED24L is lighted.Drive division 36R is used for anterior rear side LED20R, rear right LED22R and indicating device LED24R are lighted, control part 34, when being judged as that direction lamp switch 12 is connected with the 2nd contact 12b, makes right side, front portion LED20R, rear right LED22R and indicating device LED24R light.In addition, control part 34 is when being judged as that hazard warning light 14 becomes connection, and on the right side of making front left LED20L, rear left LED22L, front portion, LED20R, rear right LED22R, indicating device LED24L and indicating device LED24R light.
Next, the flow chart of Fig. 4 and Fig. 5 is followed so that the action of illumination controller 10 to be described.Fig. 4 is the flow chart lighting action representing left direction indicator light, and Fig. 5 is the flow chart lighting action representing right direction indicator light.First, what left direction indicator light was described lights action.
Control part 34 judges whether read in timing arrives (the step S1 of Fig. 4).This reads in timing is carry out synchronous timing to the timing that direction indicator light switch 12 and warning against danger lamp switch 14 apply voltage V1 off and on interval power supply extra cell 32.
If be judged as that reading in timing does not arrive in step 1, then until arrive rest on step S1, read in timing to arrive if be judged as, then control part 34 reads in the overdue bright voltage VL preventing the two ends using resistance 40 of the voltage VL(corresponding with left direction indicator light) (step S2).
Next, control part 34 judges whether the voltage VL read in step S2 is more than threshold value Vt (step S3), and voltage VL is more than threshold value Vt if be judged as, then control part 34 makes count value C1 increase progressively (step S4).
When by driver's direction of operating indicator light switch 12, direction lamp switch 12 is connected with the 1st contact 12a, or when warning against danger lamp switch 14 is switched on, because voltage VL becomes voltage V1, therefore voltage VL becomes more than threshold value Vt.In addition, when direction lamp switch 12 is not connected with the 1st contact 12a, or when warning against danger lamp switch 14 disconnects, if generation leakage current, because voltage VL becomes voltage V2, therefore voltage VL becomes below threshold value Vt, but sometimes because of the impact of noise, voltage VL becomes more than threshold value Vt.
Next, control part 34 judges whether count value C1 is more than certain value (step S5).As judging that whether count value C1 is the reason of more than certain value, owing to being judged as that voltage VL is more than threshold value Vt sometimes because of the impact of noise, therefore, in step s 5, what cause to prevent the impact of noise is overdue bright, judges that the whether continuous stipulated number of voltage VL read in step S2 is more than threshold value Vt.In other words, judge in certain time range, the mode waveform of the voltage that interval power supply extra cell 32 applies, with whether consistent at the mode waveform of the overdue bright voltage preventing the two ends of use resistance 40 from producing.
To the waveform of the pulse voltage that direction indicator light switch 12 and warning against danger lamp switch 14 apply off and on owing to being distinctive mode waveform, therefore, even if when being judged as that in the impact because of noise voltage VL is more than threshold value Vt, applying the timing of voltage V1, the voltage VL of reading also can not become more than threshold value Vt by stipulated number continuously.In addition, the frequency setting due to the pulse voltage by applying be cause higher than artificial operation frequency, lower than the frequency of ring frequency of loudspeaker being located at described saddle ride type vehicle, therefore all the more so.
In step s 5, if be judged as, count value C1 is not more than certain value, then return step S1, if be judged as, count value C1 is more than certain value, then control part 34 controls the flicker (step S6) that drive division 36L starts left direction indicator light, returns step S1.That is, the flicker of front left LED20L and rear left LED22L is started.Now, the flicker of start instruction device LED24L is gone back.In addition, when the flicker carrying out left direction indicator light, do not carry out the action of step S6, directly return step S1.
On the other hand, in step S3, if become certain value to go forward at count value C1, be judged as that voltage VL is not more than threshold value Vt, then (0) (step S7) reset to count value C1, make left direction indicator light extinguish (step S8), return step S1.Now, indicating device LED24L is also made to extinguish.When making left direction indicator light extinguish, do not carry out the action of step S8.
So, owing to carrying out synchronous reading in timing with the timing that interval power supply extra cell 32 applies voltage V1 to direction indicator light switch 12 and warning against danger lamp switch 14 off and on, read in the voltage VL corresponding with left direction indicator light, if be judged as, more than the continuous stipulated number of this voltage VL is threshold value Vt, left direction indicator light is then made to glimmer, therefore, even if when there occurs leakage current, overdue bright (by mistake the flicker) of the left direction indicator light that also can prevent the impact of noise or leakage current from causing.
Next, what right direction indicator light was described lights action.Control part 34 judges whether read in timing arrives (the step S11 of Fig. 5).This reads in timing as described above, is carry out synchronous timing to the timing that direction indicator light switch 12 and warning against danger lamp switch 14 apply voltage V1 off and on interval power supply extra cell 32.
If be judged as that reading in timing does not arrive in step 11, then until arrive rest on step S11, read in timing to arrive if be judged as, then control part 34 reads in the overdue bright voltage VR preventing the two ends using resistance 42 of the voltage VR(corresponding with right direction indicator light) (step S12).
Next, control part 34 judges whether the voltage VR read in step S12 is more than threshold value Vt (step S13), and voltage VR is more than threshold value Vt if be judged as, then control part 34 makes count value C2 increase progressively (step S14).
When by driver's direction of operating indicator light switch 12, direction lamp switch 12 is connected with the 2nd contact 12b, or when warning against danger lamp switch 14 is switched on, because voltage VR becomes voltage V1, therefore voltage VR becomes more than threshold value Vt.In addition, when direction lamp switch 12 is not connected with the 2nd contact 12b, or when warning against danger lamp switch 14 disconnects, if generation leakage current, because voltage VR becomes voltage V2, therefore voltage VR becomes below threshold value Vt, but sometimes because of the impact of noise, voltage VR becomes more than threshold value Vt.
Next, control part 34 judges whether count value C2 is more than certain value (step S15).As judging that whether count value C2 is the reason of more than certain value, owing to being judged as that voltage VR is more than threshold value Vt sometimes because of the impact of noise, therefore, in step S15, what cause to prevent the impact of noise is overdue bright, judges that the whether continuous stipulated number of voltage VR read in step S12 is more than threshold value Vt.In other words, judge in certain time range, the mode waveform of the voltage that interval power supply extra cell 32 applies, with whether consistent at the mode waveform of the overdue bright voltage preventing the two ends of use resistance 42 from producing.
To the waveform of the pulse voltage that direction indicator light switch 12 and warning against danger lamp switch 14 apply off and on owing to being distinctive mode waveform, therefore, even if when being judged as that in the impact because of noise voltage VR is more than threshold value Vt, the voltage VR read in the timing applying voltage V1 also can not become more than threshold value Vt by stipulated number continuously.In addition, the frequency setting due to the pulse voltage by applying be cause higher than artificial operation frequency, lower than the frequency of ring frequency of loudspeaker being located at described saddle ride type vehicle, therefore all the more so.
In step S15, if be judged as, count value C2 is not more than certain value, then return step S11, if be judged as, count value C2 is more than certain value, then control part 34 controls the flicker (step S16) that drive division 36R starts right direction indicator light, returns step S11.That is, the flicker of anterior right side LED20R and rear right LED22R is started.Now, the flicker of start instruction device LED24R is gone back.In addition, when the flicker carrying out right direction indicator light, do not carry out the action of step S16, directly return step S11.
On the other hand, in step S13, if become certain value to go forward at count value C2, be judged as that voltage VR is not more than threshold value Vt, then (0) (step S17) reset to count value C2, make right direction indicator light extinguish (step S18), return step S11.Now, indicating device LED24R is also made to extinguish.When making right direction indicator light extinguish, do not carry out the action of step S18.
So, owing to carrying out synchronous reading in timing with the timing that interval power supply extra cell 32 applies voltage V1 to direction indicator light switch 12 and warning against danger lamp switch 14 off and on, read in the voltage VR corresponding with right direction indicator light, if be judged as, more than the continuous stipulated number of this voltage VR is threshold value Vt, right direction indicator light is then made to glimmer, therefore, even if when there occurs leakage current, overdue bright (by mistake the flicker) of the right direction indicator light that also can prevent the impact of noise or leakage current from causing.
If by driver's direction of operating indicator light switch 12, direction lamp switch 12 is connected with the 1st contact 12a, then with the action shown in Fig. 4, left direction indicator light is glimmered, if direction lamp switch 12 is connected with the 2nd contact 12b, then with the action shown in Fig. 5, right direction indicator light is glimmered.In addition, if make hazard warning light 14 connect by the operation of driver, then with the action shown in Fig. 4 and Fig. 5, left direction indicator light and right direction indicator light are glimmered simultaneously.
As described above, illumination controller 10 according to the present embodiment, generate the voltage of the distinctive mode waveform for identifying leakage current due to interval power supply extra cell 32 and direction indicator light switch 12 and warning against danger lamp switch 14 are applied, therefore, the voltage V1 applied by reducing interval suppresses the generation of leakage current, can prevent the light device 16 of the impact of due to leakage current overdue bright, because of light device 16 overdue bright of the impact of noise.
Interval power supply extra cell 32 generate the pulse voltage of having modulated frequency and (or) generate the different multiple pulse voltages of duty ratio, therefore, even if when making S/N than when reducing by making the voltage that applies off and on less, the overdue bright of light device 16 also can be prevented.
Interval power supply extra cell 32 is owing to generating the frequency that causes higher than artificial operation and lower than the pulse voltage of frequency of ring frequency of described loudspeaker being located at described saddle ride type vehicle, therefore, the ring frequency of the frequency that the frequency of pulse voltage generated can not cause with artificial operation and loudspeaker overlaps, and can improve the overdue bright of light device 16 and prevent precision.
To the voltage of voltage owing to being 0 ~ 2 volt that direction indicator light switch 12 and warning against danger lamp switch 14 apply, the generation of leakage current therefore can be suppressed.
More than use suitable execution mode to be illustrated, but technical scope of the present invention is not limited to above-mentioned execution mode.Can add various change or improvement in the above-described embodiment, this is apparent for those skilled in the art.The form adding such change or improvement also can be included in technical scope of the present invention, and this point obtains clearly in the record of the scope of claim.In addition, the symbol that the symbol in the bracket described in the scope of claim imitates in accompanying drawing adds, and should not be construed as the present invention and is defined in the key element having added this symbol.
