Detailed Description

The following description of the embodiments with reference to the drawings is provided to explain the embodiments of the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connection relationships among the components, the functions and working principles of the components, the manufacturing process, and the operation and use method, etc., so as to help those skilled in the art to understand the concept and technical solutions of the present invention more completely, accurately and deeply.

In fig. 1, an intelligent headlamp system of an intelligent vehicle includes a camera 1, a positioning module 2, a central processing unit 3, a headlamp control driving execution module 4, and a headlamp execution mechanism module 5.

The camera 1 is used for detecting whether a high beam is turned on by an incoming vehicle of a front object, detecting whether a vehicle exists in the front and detecting the front running environment. When an object arrives at the vehicle, the front-looking camera 1 judges whether the vision system can accurately detect and identify the traffic condition in front or not, and if a video image is captured in a blank state, the lane line, the vehicle and the pedestrian in the traffic environment cannot be identified. The high beam of the vehicle is not only required to be turned off, but also is automatically controlled to flicker by the control logic until the high beam of the target vehicle is turned off. Whether the high beam of the oncoming vehicle is turned off or not is judged according to the contrast of the video image captured by the front-view camera of the vehicle. In addition, if a vehicle exists in front of the vehicle, the high beam of the vehicle is turned off through a control logic algorithm, so that the driving safety is improved.

The positioning module 2 combines the camera 1 to realize visual positioning, and the positioning module 2 is GPS or big dipper location, can acquire the vehicle position in real time to can know the road information that will go according to positioning information cooperation map information, if will get into the bend, will get into the uphill road section etc..

And after the vehicle passes through the right turning road section, the right supplementary lighting lamp is turned off in the same way. The left side or the right side light filling lamp is automatically turned on to light the road environment of the side to be turned, the advance perception of the camera 1 to the front environment can be improved, and the driving safety at night can also be improved.

When the road condition in front is judged to be an uphill road section, when the vehicle is about to enter the uphill road section, the headlamp control algorithm 33 sends a control command to the headlamp drive control module 4, and the headlamp drive control module 4 controls the high beam focal length adjusting mechanism 53 and the dipped headlight focal length adjusting mechanism 54 to adjust the focal length of the high beam and the low beam, so that the pitch angle is increased, the high beam and the low beam illuminate the farther range of the uphill road section, and the night driving safety of the uphill road section is improved.

When the road condition in front is judged to be a downhill section, when the vehicle is about to enter the downhill section, a control instruction is sent to the headlamp drive control module 4 through the headlamp control algorithm 33, and the headlamp drive control module 4 controls the high beam focal length adjusting mechanism 53 and the dipped headlight focal length adjusting mechanism 54 to adjust the focal length of the high beam and the low beam, so that the pitch angle is reduced, the high beam and the low beam illuminate a farther range of the downhill road, and the night driving safety of the downhill section is improved.

When the positioning module 2 judges that the road in front is an uphill road or a downhill road, the focal length of the high beam is automatically adjusted, the pitch angle of the high beam is adjusted, and the lighting blind areas of the traditional vehicle during uphill driving and downhill driving are overcome.
