Hereinafter, the operation that description is had the vehicle autolights system of said structure.
Fig. 5 represents the diagram of circuit of the job procedure of vehicle autolights system according to an embodiment of the invention.In Fig. 5, " S " represents step.
Usually, lamp portion 40 does not work when vehicle is in fired state yet even light switch 10 is in the state of cut-offfing by day.But, according to the present invention, by non-attended light control circuit 20 being set when vehicle is in fired state, light switch 10 can automatically be converted to open mode, and non-attended light control circuit 20 can satisfy the functional burdening of the indicator lamp of connecting daytime to avoid vehicle generation traffic accident.
The operation of vehicle autolights system is described in the supposition that is in on-state according to light switch 10.
At first, when chaufeur started vehicle, light switch test section 208 detected light switch 10 and whether is in on-state, and detection signal is transferred to control part 209.In case receive the signal of light switch test section 208, whether control part 209 is automatic mode (S1) according to the pattern of this signal check light switch 10 just.
If the pattern of light switch 10 is automatic modes, then be installed in the lip-deep luminous flux detection sensor of front window feather edge 2011 with regard to detected resistance, this resistance changes according to the light quantity that incides on the vehicle front window.In addition, the luminous flux detection portion 201 that comprises luminous flux detection sensor 2011 and resistance R 1 gives control part 209 with the luminous flux detection signal output.
In case receive the luminous flux detection signal, control part 209 just compares this luminous flux detection signal and predetermined reference value, determines with this whether is daytime (S2) this moment.If be not daytime this moment, then control part 209 just checks whether is the dusk (S3) this moment.
If be that control part 209 is just exported to first relay 2031 by second switch 206 with the PWM connection signal and connected first relay 2031 at dusk at this moment, second switch 206 is used for the taillight of on/off lamp portion 30 automatically.
When connecting first relay 2031, the cell pressure that power supply unit 40 provides inputs to the taillight of lamp portion 30 can connect taillight (S4).Taillight is according to being controlled by the intelligent algorithm of the variable dynamic threshold management of two fixed thresholds and two, so as taillight at candlelight opens, pass shaded area at vehicle, or when vehicle ' is below elevated line, do not open.This intelligent algorithm can be applied to various vehicles and differently not set its controlling valu so that it does not need according to the kind of vehicle.
After taillight was opened, the resistance that changes according to the vehicle periphery illumination intensity detected can determine whether is night (S5) this moment continuously by luminous flux detection sensor 2011.If be not night this moment, program just turns back to step S4.
If be night at this moment, control part 209 is just exported to second relay 2032 by second switch 206 with the PWM connection signal and is connected second relay 2032, and second switch 206 is used for the headlight of on/off portion 30 automatically.
When connecting second relay 2032, the cell pressure that power supply unit 40 provides inputs to the headlight of lamp portion 30 connecting headlight (S6) with the brightness of PWM 100%.At this moment, the brightness of headlight can be carried out multistage adjusting by the program conversion pulse-width signal that is stored in the control part 209 according to the illumination intensity that luminous flux detection portion 201 is detected.
Then, vehicle moves the speed that test section 202 detects vehicle, and gives control part 209 as the mobile status detection signal with transmitted with car speed.In case receive the mobile status detection signal, control part 209 just determines whether vehicle is in temporary term stop state (signal is waited for: kept constant R.P.M in 10 seconds) (S7).
If vehicle is in the temporary term stop state, control part 209 just changes brightness or the shutoff headlight (S8) of pulse-width signal can reduce headlight.
Then, vehicle moves test section 202 and detects car speed continuously, the mobile status detection signal that control part 209 moves test section 202 transmission according to vehicle is determined vehicle whether begin to travel (S9) after temporary term stop finishes, if vehicle begins to travel, this program just is back to step S6, and the while is with the brightness operation headlight of PWM 100%.
The brightness of headlight is controlled by PWM according to illumination intensity.At night, but headlight Be Controlled and have the brightness of PWM 100%.In addition, as mentioned above, the learning functionality of intelligent vehicle mobility joins in the control part 209.That is, control part 209 is understood the dynamic characteristics of driving engine R.P.M, so that control part 209 executivecontrol function when vehicle ' stops control operation when vehicle stops.If vehicle is not because when traffic tie-up and low running speed, the control operation of control part 209 is just carried out.
If vehicle does not begin to exercise, then control part 209 just determines that vehicle is in dead ship condition, so that control part 209 is exported to first and second relays 2031 and 2032 with PWM one cut-off signal, turn-off first and second relays 2031 and 2032 with this, thereby close lamp portion 30.
When first and second relays 2031 and 2032 turn-offed, the cell pressure of supplying with lamp portion 30 by power supply unit 40 just was cut off so that lamp portion 30 is closed (S 10).
In the case, if chaufeur is wished the portion of turning on the light 30, he is with regard to necessary operating light switch 10, that is, chaufeur must be turned on turn-on lamp switch 10 so that open required lamp.In the case, light switch test section 208 detects the operation of light switch 10, and sends a signal to control part 209.At this moment, control part 209 determines according to the signal that is input into this from light switch test section 208 whether the pattern of light switch 10 is second manual modes (S11) that can force on/off lamp portion 30.
Though lamp portion 30 is by SELF CL when vehicle parking, if but chaufeur wants to continue to keep the opening of lamp portion 30, his switch 10 that just turns on the light in the schedule time after light switch 10 is closed, thus realize keeping continuously second manual mode of the opening of lamp portion 30.
That is, light switch test section 208 transmission signals is continuously given control part 209, so that control part 209 can be converted to manual mode with automatic mode by the mode of acquiescence.
Therefore, light switch test section 208 is connected first or second relay 2031 or 2032 so that power supply can offer lamp portion 30.
In addition, if light switch 10 is not back to on-state in the given time, control part 209 just definite chaufeurs are not thought operating light portion 30, so can keep the off state of first and second relays 2031 and 2032 continuously.
In second manual mode, control part 209 allows the taillight of lamp portion 30 to keep 15 minutes opening, allows the headlight of lamp portion 30 to keep 5 minutes opening (S12), and after this, this program is returned step 1.
If determine it is daytime in step 2, control part 209 just connects second relay 2032 so that headlight is used as the relay indicating light on daytime for second relay 2032 by output pwm signal.
When second relay 2032 is connected, the cell pressure that provides by power supply unit input to headlight so that the brightness that headlight is opened in about 20%-70%PWM scope.At this moment, the brightness of headlight can be carried out multistage adjusting by the program conversion pulse-width signal that is stored in the control part 209 according to the illumination intensity that luminous flux detection portion 201 is detected.
In addition, vehicle moves the speed that test section 202 detects vehicle, and gives control part 209 as the mobile status detection signal with transmitted with car speed.In case receive the mobile status detection signal, control part 209 just determines according to the mobile status detection signal whether vehicle is in temporary term stop state (S22).

In addition, if pattern is not an automatic mode in step S1, chaufeur is just turn-offing light switch 10 back turn-on lamp switches 10 with the manual on/off lamp portion 30 of energy, and light switch test section 208 detects the operation of light switchs 10, and outputs signal to control part 209.In case receive the signal of light switch test section 208, control part 209 just determines according to this signal whether this pattern is first manual mode (S31) of manually on/off lamp portion 30.
If this pattern is first manual mode, lamp portion 30 just carries out manual on/off by M/C light switch 10.If this pattern is not first manual mode, this program just is back to step 11.
In addition, if lamp portion 30 opens, Amperometric Detection Coupled portion 204 is with regard to the magnitude of current of detection effect in lamp portion, and current detection signal is sent to control part.Therefore, control part 209 is checked current value, if current value is in the predetermined reference value, just determines that lamp portion 20 is under the normal condition.
If current value is greater than or less than predetermined reference value, control part 209 is just determined one of them headlight and taillight et out of order at least, so control part 209 just sends to buzzer switch 207 with beep sound command signal.Therefore, buzzer switch 209 just is switched on, and produces beep sound with this.Therefore, chaufeur can easily be observed headlight or taillight.
