The seventh sensor 37 is a leveling sensor used to detect the inclination of the vehicle by comparing the height difference between the front and rear of the vehicle when a cargo or a passenger rides in a sudden braking, rapid acceleration or rear seat. When the inclination of the vehicle is detected by the seventh sensor 37, the controller 40 to be described later automatically adjusts the beam irradiation angle of the inclined headlamp 10 to maintain the originally designed beam irradiation angle. .

The leveling sensor is used to detect the inclination and output the inclination signal when a passenger is in the rear seat of the vehicle or the luggage is loaded in the trunk and the front part of the vehicle is inclined to be lifted upward.

Each of the sensors 31, 32, 33, 34, 35, 36, 37 is not limited to the present embodiment, and various structures or various types of sensors may be used.

By using a low pass filter, the high frequency noise is eliminated or a proper hysteresis width is basically determined so that the signal input of each sensor does not have a sensitive response to a noise signal or an unstable signal. It is desirable not to have a sensitive response to a shaking signal.

As illustrated in FIG. 1, the control device 40 includes a memory 42 storing table map information corresponding to each piece of information detected by the sensing device 30, and table map information corresponding to an input signal. The microcomputer 44 selects and outputs a control signal based on the information.

The memory 42 selects an illumination pattern (beam irradiation direction conversion or selective on / off of the head lamp) of the head lamp 10 in response to respective information detected from each sensor of the sensing device 30. Stores table map information for each sensor input.

The microcomputer 44 selects any one of the table map information stored in the memory 42 in response to an input signal of at least one sensor from the sensing device 30 to control the irradiation angle of the headlamp 10. When outputting a signal or a plurality of headlamps 10 are configured to output an on / off control signal.

Further, according to another embodiment, different weights are assigned to table map information for each sensor input, and one of the highest weights is selected from the illumination pattern information searched for each sensor input. In other words, when information is input from one or more sensors, the headlamp 10 controls the driving device 50 to select one of the input weights having the highest weight among the input information. However, the illumination pattern screening method is not limited thereto, and various methods are provided.

For example, when the driving device 50 is configured to adjust the irradiation angle of the headlamp 10 as described above, the respective irradiation angles retrieved from the table map information for each sensor input may be added up. One of the retrieved irradiation angles may be selected and controlled, and the weights of the table map information for each sensor input may be different and the weights may be calculated for each irradiation angle information searched for each sensor. This can be summed up.

On the other hand, the control device 40 may control the brightness of the head lamp 10 by adjusting the current strength applied to the head lamp 10, the left lamp (A, B, C, D) and the right lamp In addition to the mechanical configuration of the drive autonomous 50 configured to control the irradiation angle of the headlamp 10 to (A ', B', C ', D'), each lamp is selectively on / off controlled. The irradiation angle can be controlled to be adjusted.

In particular, when the headlamp 10 is composed of a plurality of lamps, the control device 40 is suddenly turned on when the vehicle corresponding to the rotational direction is extinguished if the vehicle goes straight again after rotating the curved road. It is preferable to have a pulse width modulator (PWM) so as not to turn off. The feeder buoyem is to control the output by adjusting the width of the operating pulse applied to the lamp, which is to solve the driver's anxiety caused by the lamp is suddenly turned off.

Meanwhile, the control device 40 further includes a decoder 103 for selecting stored table map information in response to the input detection signal. In addition, the headlamps 10 may be configured to be controlled at different irradiation angles. That is, the headlamp 10 of one side can be rotated to the left, and the headlamp 10 of the other side can be rotated to face the front. This is to form more various lighting patterns.

Referring to the operation of the first embodiment according to the present invention configured as described above are as follows.

First, when power is applied as shown in FIGS. 1 to 4A, the control device 40 is initialized. That is, the head lamp 10 is turned on or the irradiation angle is returned to the initial state.

Subsequently, when a detection signal is input from each sensor 31, 32, 33, 34, 35, 36, 37 of the plurality of sensing devices 30, the control device 40 determines the current state of the vehicle.

That is, the control device 40 is to determine the driving speed, the surrounding conditions, the driving state and the like of the vehicle according to the input information.

At this time, the control device 40 determines the illumination pattern by comparing and analyzing the input information and the information stored in the memory 42.

In other words, the input information is compared and analyzed to form a driving beam illumination pattern suitable for a general road, a driving beam illumination pattern suitable for a highway, and a driving beam suitable for a city road, a bad weather, a city road, or the like. It is to decide whether or not to form a complex lighting pattern.

To this end, the microcomputer 44 selects any one of the table map information 105 in response to a signal input for at least one sensor from the sensing device 30, and based on the selected table map information. The irradiation angle control signal is output.

This will be described in more detail as follows.

As shown in FIG. 4A, when at least one input signal for each sensor is input to the decoder 103 from each sensor of the sensing device 30, the decoder 103 controls the irradiation angle stored according to the input signal. A signal for selecting the corresponding table map information from the table map information 105 for signal output is output. Therefore, when one or more signals are input from each sensor, the decoder 103 outputs a corresponding signal to select corresponding table map information from the memory 42, and the microcomputer 44 based on the table map information. By outputting the irradiation angle control signal of the head lamp 10 to the drive device 50.

For example, when a detection signal from the first sensor 31 and the second sensor 32 is input to the decoder 103 at the same time, the decoder 103 outputs one signal corresponding thereto, and accordingly The table map information corresponding to the signal is selected to output an irradiation angle control signal suitable for an external situation detected by the first sensor 31 and the second sensor 32. At this time, each table map information stored in the memory 42 is preset and stored according to the number of cases.

When the irradiation angle control signal of the headlamp 10 is output as described above, the driving device 50 operates as follows.

That is, as shown in FIGS. 2A and 2B, the driving device 50 controls the upper and lower operating actuators 53 or the left and right operating actuators 55 according to the irradiation angle control signal to control the headlamp 10. The beam irradiation angle is adjusted to operate by the irradiation angle set around the pivot 51.

Meanwhile, referring to the present invention according to the second embodiment, as shown in FIG. 6, the head lamp 10 includes the left lamps A, B, C, and D and the right lamps A ', B', and C. As shown in FIG. ', D'), and if the driving device 50 is equipped with a driver 59, the control device 40 is a sensor of the sensing device 30 as shown in Figure 4a or 4b One of the table map information 107 for on / off control stored in the memory 42 is selected in response to the input signal of at least one sensor.

That is, when a signal is simultaneously input from the fifth sensor 35 and the sixth sensor 36, the decoder 103 outputs a signal to select the table map information corresponding thereto, and thus the microcomputer 44 selects the selected table. An on / off control signal is output to the driver 59 based on map information, and the driver 59 has left lamps A, B, C, and D and right lamps A ', B', and C. ', D') to only turn on or off the selected lamp to form an illumination pattern (beam irradiation direction) suitable for the detected ambient conditions.

In the above, the respective embodiments in which the control device 40 selects any preset and stored table map information corresponding to the input signal to output the irradiation angle or the on / off control signal have been described.

Hereinafter, an operation of each embodiment configured to weight each table map information and to select the table weight information having the highest weight among the selected table map information to output the irradiation angle control signal or the on / off control signal will be described.

That is, the control device 40 searches the table map information for each sensor input according to the input information for each sensor, and determines, that is, selects, an illumination pattern of the headlamp 10 based on the search result. By selecting one of the highest weight among the respective illumination pattern information searched for each sensor input, by selecting any one of the highest weight among the sensor information input from the sensing device 30 to control accordingly The signal is output to the driving device 50.

At this time, if the driving device 50 is configured to adjust the irradiation angle of the headlamp 10, and the table map information stored in the memory 42 is information for adjusting the irradiation angle of the headlamp 10, The control device 40 controls the upper and lower operation actuators 53 or the left and right operation actuators 55 of the driving device 50.

For example, if the information having the highest weight is speed information of the second sensor 32 for detecting the speed of the vehicle, the faster the speed of the vehicle, the farther the driver should secure a long distance clock. ) Operates the upper and lower operating actuators 53 so that the headlamp 10 is angled upward by an angle set upward from the pivot 51 while the first operating end 52 is tensioned. The angle is raised so that the light automatically illuminates the distance according to the speed of the vehicle.

At this time, if the driving device 50 according to the second embodiment is controlled, as shown in Figure 3a, the first link (57A) and the second link (57C) of the up and down drive unit 57 is a reflector 14 The first driving motor 57B is driven so that the reflector 14 is angled upward with respect to the fixing member 56 by pushing ().

On the other hand, when the vehicle travels at an intersection or a curved road and the rotation direction is to the left, a clock in the direction in which the driver rotates should be secured. Therefore, if the input information of the fifth sensor 35 for detecting the steering angle has the highest weight, the control device 40 prioritizes the other input information to the table map information corresponding to the fifth sensor 35. On the basis of this, a control signal for controlling the driving device 50 is output.

That is, the headlamp 10 controls the driving device 50 to adjust the irradiation angle in the rotational direction of the vehicle.

For example, when it is detected that the vehicle rotates to the right side, the microcomputer 44 searches the table map information for the irradiation angle according to the steering angle and outputs a control signal based on this to the driving device 50. If the driving device 50 is a component according to the first embodiment, the left and right operating actuators 55 operate to tension the second operating end 54. Subsequently, when the second operating end 54 is tensioned, the headlamp 10 is rotated by an angle set to the right about the pivot 51.

In addition, if the driving device 50 is a component according to the second embodiment, as shown in FIG. 3B, the second driving motor 58B of the left and right driving units 58 is driven to drive the fourth link 58C. And the third link 58A, which causes the third and fourth links 58A and 58C to be unfolded, thereby rotating the reflector 14 to the right about the fixing member 56 to irradiate the headlamp 10. The angle is toward the right direction the vehicle is to turn.

Therefore, the driver can sufficiently secure the road clock in the rotational direction.

On the other hand, if one or more information is input to the control device 40 from each sensor (31, 32, 33, 34, 35, 36, 37) of the sensing device 30, the microcomputer 44 is for each sensor The table map information is searched for each sensor input according to input information, and an illumination pattern of the head lamp 10 is selected based on the search result, wherein the illumination pattern is selected for each sensor input as described above. Different weights are assigned to the table map information, and one of the highest weights is selected from the respective illumination pattern information searched for each sensor input. In this case, the table map information is irradiation angle information as shown in Figs. 5a to 5g.

The input information for each sensor stored in the memory 42 is assigned a weight as shown in FIGS. 5A to 5G. In this state, the information on the uplight lighting state of the first sensor 31 for detecting the uplight lighting state of the headlamp 10, the speed information of the second sensor 32 for detecting the speed of the vehicle, and moisture When moisture sensing information of the third sensor 33 for sensing is input from the sensing device 30 to the microcomputer 44, the microcomputer 44 selects information having the highest weight among the respective information.

That is, when the headlamp 10 is turned on, the weight is 10%, when the speed of the vehicle is 90km / h, the weight is 30%, and when the fog or rain water is detected, the micom 44 has a weight of 20%. From the information input from the first sensor 31, the second sensor 32, and the third sensor 33, the speed information of the vehicle having the highest weight is selected to drive an irradiation angle control signal corresponding to 90 km / h. 50). In this case, the irradiation angle corresponding to 90 km / h is 2 ° as shown in FIG. 5B, so that the driving device 50 operates the upper and lower operation actuators 53 so that the headlamp 10 is centered on the pivot 51. Rotate upward by 2 ° so that the headlamp 10 forms an illumination pattern for illuminating a long distance.

In this case, the driver must obtain a long-distance watch rather than a short distance because it is a bad rain or rainy weather when the vehicle is traveling at a speed of 90 km / h. Therefore, when the irradiation angle of the headlamp 10 is adjusted upward by 2 °, the irradiation angle condition in bad weather and the irradiation angle condition according to the vehicle speed are satisfied.

In addition, even when the respective information is input from the fourth sensor 34, the fifth sensor 35, and the sixth sensor 36, the irradiation angle is selected so as to match any of the highest weights among the respective information as described above. It will output the control signal.

On the other hand, when the table map information is lamp on / off information is controlled as follows.

As shown in FIGS. 7A to 7G, in the state in which the input information for each sensor is weighted, from the fourth sensor 34 among the first sensors 31 to the seventh sensor 37 of the sensing device 10. Assuming that the information that the ambient brightness is 5Lx or less, the information that the steering angle is + 20 ° (to the right) from the fifth sensor 35 and the information that the vehicle speed is 120 km / h from the second sensor 32 are simultaneously input, If the ambient brightness is less than 5Lx, the weight is 12%, the steering angle is + 20 °, the weight is 10%, and when the vehicle speed is 120km / h, the weight is 50%, the information of the second sensor 35 The weight is the highest.

Accordingly, the microcomputer 44 outputs a control signal for turning on both the left lamps A, B, C, and D and the right lamps A ', B', C ', and D'. Causes the left lamps A, B, C, and D and the right lamps A ', B', C ', and D' to light up.

In this case, when the vehicle is driving at a high speed of 120 km / h, the left lamps A, B, C, and D and the right lamps A ', B', C 'and D' are both turned on to drive at high speed. Along the front clock, that is, the side, near, long distance, such as a watch can be sufficiently secured.

At this time, when the steering angle is 20 ° (to the right) and when the vehicle speed is 120 km / h, the weight of the vehicle is high and the illumination pattern suitable for high-speed driving is formed, but the left lamps A, B, C, D) and the right lamps (A ', B', C ', D') are turned on so that not only the front side but also the side lamps to turn are turned on, resulting in sufficient visibility of the front of the vehicle and the direction to turn do.

On the other hand, information that the ambient brightness is 5Lx or less from the fourth sensor 34 of the sensing device 10, information that the steering angle is + 90 ° (to the right) from the fifth sensor 35, and the sixth sensor 32 Assuming that 100m distance from the vehicle in front is inputted simultaneously, the weight is 12% when the ambient brightness of the vehicle is less than 5Lx, and the weight is 21% when the steering angle is + 90 °. Since the weight in the case of 20m is 4%, the information weight of the fifth sensor 35 is the highest.

Accordingly, the microcomputer 44 turns off the left lamps A and B located at the leftmost side among the left lamps A, B, C and D and the right lamps A ', B', C 'and D'. Outputs a control signal for turning on all remaining lamps, and causes the driver 59 to have left lamps C and D and right lamps A ', B', C 'and D except the left lamps A and B. Make sure all the lights are on.

If the left lamps (C, D) and the right lamps (A ', B', C ', D'), except for the left lamps (A, B), are turned on in this manner, ensure sufficient visibility in the direction in which the vehicle intends to turn. The lighting pattern is formed so that the driver can sufficiently secure the clock in the direction to rotate.

In this series of motions, even if the driver does not select the system, the system detects the surrounding conditions, road conditions, and vehicle conditions, and automatically forms the appropriate lighting pattern. Therefore, the driver ensures the best visibility regardless of the road conditions or surrounding conditions. Done.

In each of the above embodiments, the illumination pattern of the headlamp 10 is automatically generated by selecting any one of the table map information corresponding to the input signal of at least one sensor and outputting an irradiation angle control signal or an on / off control signal. The system is controlled to convert or form a lighting pattern by weighting each piece of information and then outputting the irradiation angle control signal or the on / off control signal corresponding to the information with the highest weight. However, various modifications will be possible without being limited thereto.
