Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of car bulb height adjusting system one of the present invention preferred embodiment；
Fig. 2 is the circuit diagram of voltage output module in a preferred embodiment of the present invention.
Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, technical scheme is made further
Describe, but the present invention is not limited to these embodiments.
Refer to Fig. 1, the car bulb height adjusting system of the application includes that adjustment module 100, voltage are defeated
Go out module 200, control module 300 and motor control panel 400.
Adjustment module 100 sends the instruction of regulation light height for the operation according to user or road conditions.
In the application, car bulb height can be dazzle light light height, it is possible to high for automobile dipped headlight light
Degree.
Adjustment module 100 can be manual adjustment knob, chooses car bulb by the manual turn knobs of user
Highly gear；Alternatively it is automatically adjusted module, such as, automatically sends out according to running car road conditions, angle of turn etc.
Go out car bulb height gear regulation signal.
After adjustment module 100 sends regulation signal, voltage output module 200 exports different magnitudes of voltage.Electricity
Pressure output module 200 can use multiple circuit mode, as long as it can export different magnitudes of voltage.Example
As used the swept resistance mode shown in Fig. 2, by change and then the electricity of change output of swept resistance resistance
Pressure value.May be used without the mode by multiple resistor coupled in parallel or series connection, make when adjustment module sends regulation signal
The resistance value obtaining multiple resistance access circuits changes and then changes the magnitude of voltage of output.
When using swept resistance, the magnitude of voltage that magnitude of voltage is continuous variable of voltage output module 200 output.
When using the mode of multiple resistor coupled in parallel or series connection, voltage output module 200 output magnitude of voltage be multiple not
Same voltage point value.
Now, voltage output module 200 output magnitude of voltage be analogue signal, if using this analogue signal as
Control signal controls the operation of motor then can produce the problems such as low, the motor vibrating of control accuracy.
In the application, the magnitude of voltage (analogue signal) of voltage output module 200 output is first delivered to control mould
Block 300, control module 300 exports the numeral of correspondence after calculating the car bulb height that this magnitude of voltage is corresponding
Control signal.Concretely, pre-stored difference light height is corresponding in control module 300 magnitude of voltage or
Range of voltage values, it is judged that the magnitude of voltage of reception is positioned at which grade preset voltage value scope and then the number of output correspondence
Word control signal.
Control module 300 can use the control modules such as conventional single-chip microcomputer, it is possible to is integrated in the control of automobile self
In molding block.Control module 300 completes control signal by analog quantity (magnitude of voltage) to the transformation of digital quantity.
General close together with adjustment module due to control module 300, therefore line loss is less, does not interferes with
The degree of accuracy of output voltage.In a preferred embodiment, also can be defeated with voltage by control module, adjustment module
Go out module to become one.
The digital controlled signal of control module 300 output is by automobile CAN-bus or LIN bus transfer extremely electricity
Machine panel 400.Be converted to export the electricity to motor by this digital controlled signal by motor control panel 400 again
Pressure.
In the application, between control module 300 and motor control panel 400, use CAN or LIN bus
Carry out digital data transmission, it is to avoid vehicle other disturbance of electronic signal.
Digital signal both will not occur line loss in transmitting procedure, also because of ground wire fluctuation, ripple will not occur
Dynamic so that car bulb altitude mixture control precision is relatively high and stable.In the present embodiment, twice voltage signal with
Digital controlled signal conversion each other all occurs in nearer two parts of mutual distance, such as motor control
Between making sheet and motor, voltage output module and control module, reduce loss and the ripple of voltage signal as far as possible
Dynamic.
In a preferred embodiment, control module 300 also receives automobile start stop signal, believes according to automobile start and stop
Number with voltage output module output magnitude of voltage calculate the car bulb height that this magnitude of voltage is corresponding.Automobile is opening
Time dynamic, magnitude of voltage fluctuation is more severe, if now exporting digital controlled signal according to original criterion, and can
Can be able to judge by accident.In the present embodiment, if automobile start stop signal being detected, then use default another set of
Magnitude of voltage correspondence light Height Standard, or before calculating magnitude of voltage correspondence light height, remove automobile start and stop
The impact that magnitude of voltage is fluctuated by signal.
Specific embodiment described herein is only to present invention spirit explanation for example.Belonging to the present invention
Those skilled in the art described specific embodiment can be made various amendment or supplement or
Similar mode is used to substitute, but without departing from the spirit of the present invention or surmount appended claims institute
The scope of definition.
