Two headlights are mainly used to assist driving A = condition and the position of the front and opposite vehicles, but the early vehicle headlights are fixed on the front side of the vehicle and can only be illuminated to the front, such a When driving at night, it is easy to cause the body to tilt due to road undulations, thereby changing the range that the headlights can reach, affecting the front visibility of the driver; in addition, if the car is driving on uneven roads, the road is undulating. It will cause the front of the car to be lifted continuously, causing the driver in front to feel the strong glare when watching the rearview mirror. This will affect the driver of the car and observe the rear car condition through the rear mirror. Especially when the headlights use high-illumination discharge lamps (out When you call it "_ Lamp, HID Lamp", the impact is even greater. : To solve the above problems, some manufacturers have proposed a smart type of headlight control 2, a new patent case No. 281 836, which is mainly composed of - Ma Lilian: Γ optical static sensor and a control element, the motor is The pitch angle between the soap head lamp and the ground: the sensor is mounted on the chassis of the vehicle to confirm the posture of the vehicle, and the control unit controls and receives the message sent back by the sensor, thereby driving the motor Perform light control function, wherein: the multi-segment optical static sensor is arranged under the chassis of the car, and is equipped with a photointerrupter at each different angle, using 1298297 ===: rod, shaft and The arm causes the crying of the sensor to be interrupted.

The height of the lamp is high and low, and the road condition is timely. It is suitable for the upper and lower slope change sections. Therefore, it can be clear that the change angle of the tilt angle of the vehicle body is higher. '% to a lower adjustment frequency (for example - every six seconds) Change the height angle of the headlights, mainly = the vehicle headlights are continuously adjusted, thereby enhancing the driver's line of sight: and extending the service life of the actuating unit... less: [Embodiment] One; Ben; Ming Automatic control device for the headlights of the vehicle: The example is installed on the vehicle (10). Please refer to the figure shown in the first page. The beans are mainly transmitted to the dry.. /, the brother is activated... The road condition detection unit (20) and - the wringing is 7L (30) early. The road condition detection unit A (2 〇) is a modular circuit solid (1 〇) chassis inner side, and includes: a two-in-one microprocessor and a control program (21) having a built-in standard illumination height data. Wherein the beam quasi-illumination height data is 5 1298297 when the vehicle is in trouble, the headlight of the headlight is defined by the height, and the control procedure is detailed later; an acceleration sensor (G ςΡης^ , / , if _ 9 ,, GSenS〇r (2 2), is connected to the micro-reactor (2 1 ) to detect the relative angle of the six-inch and the acceleration sensor (2 2 ) and send it to the micro-processing cry Σσ ( 2 1 ), obtained by the microprocessor (2 1 ) to obtain a vehicle tilt #自贝 oblique angle (〇 (as shown in Figure _); general acceleration sensor is used to sense 敎 ^ ^ ^ ..., early force, test corner force and linear acceleration' and the invention is to apply the acceleration and salt, and the state is applied to calculate the inclination angle of the vehicle. The self-actuation single το (3 〇) is connected to the road condition detection list. The microprocessor (2)), the old man J丄) is compared to the vehicle tilt angle (α) by the processor (10) And Ling Xuan into Zhao ^ ^ ^, Hai Xinfeng illuminate the South 纟 data I, drive the actuation unit (30) to adjust the headlights (] Guo Pingbei and I 1 1) high and low angles of illumination, The actuating unit (3 〇) can be used for the purpose of driving the headlights to adjust the angle, such as the Kyrgyzstan, the ancient people, the go, and the straight/;, L motor, stepper motor, solenoid valve or induction coil. : In the above control program 'please refer to the third figure; it includes the following steps · Determine the vehicle tilt angle () value (100). If the frequency of change of month (α) is greater than a standard if the standard value is A lower adjustment frequency changes the south low angle of the head 1) (101); if the right is less than the standard value, the height angle (102) of the headlight (11) is changed at a higher adjustment frequency. In the present embodiment, the standard value of the vehicle tilt angle 纟 ") is changed every six seconds; and for the higher and two 1298297 _ rates, in this embodiment, each time is -second And adjust the height and angle of the headlights (1 1) every six seconds, where m (the souther frequency) and the headlights (lower operating frequency) are adjusted every six seconds (lower operating frequency) The difference lies in the fact that the operating frequency is more suitable for the upper and lower slopes when it is more suitable for the road conditions; and the lower the operating frequency is more suitable for driving on the non-flat road, and it is not necessary to frequently control the lights to change the angle. If the general vehicle just enters the uphill section, the range of the illumination will be reduced by the uphill section. The control device of the present invention can immediately tilt the body. The fifth picture does not 'and thus raises the angle of illumination of the front 35 (1 1 ) earlier, so that the headlights (1 1 ) can be pre-illuminated on the uphill section to reduce the visibility of the vehicle when entering the uphill section, thus helping At night As can be seen from the above, the present invention is based on the fact that the road condition detecting unit handles a number of strictnesses, so that the microprocessor determines whether the beam is broken or not, depending on the tilting state of the vehicle::: headlight irradiation The high and low angles, more importantly, the road condition of the present invention: the early detection system is a modular circuit, and the acceleration sensor is used to detect that the vehicle is beveled, so the road condition detection unit of the present invention is more conventional than the conventional one. Self-protection: the mechanical sensor inside the device will be more convenient; in addition, the method can be used to judge the change frequency of the car _ oblique, and the difference between the high and low angles of the headlights is changed. Therefore, the setting can be improved according to different road conditions.
