[0002] When the car is driving, if the road surface changes, the car's lighting angle should also change accordingly to ensure driving safety. When going uphill, the road in front of the vehicle is relatively elevated. If the headlight angle is not adjusted, the light will shine into the sky, resulting in insufficient lighting of the road nearby and glare to oncoming vehicles. The opposite is true when going downhill. If it is not adjusted, the light will shine too close and cannot be seen clearly from a distance. When turning, due to the steering of the vehicle body, the original headlight illumination direction cannot cover the curve area well, and the blind spot is large, making it difficult for the driver to immediately discover potential dangers.

[0003] At present, the illumination angle of the headlights of automobiles needs to be adjusted manually, and it is not easy to change automatically according to the driving dynamics of the automobile, and the flexibility and intelligence are not strong enough.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please see attached Figures 1 to 4 As shown, an automobile control system with a dynamic detection function in an embodiment of the utility model includes a vehicle controller 2, the vehicle controller 2 is connected to a vehicle dynamic detection module 1 and a motor controller 3, the motor controller 3 is connected to a headlight adjustment mechanism 4, when the vehicle is driving, the vehicle dynamic detection module 1 transmits the vehicle dynamic information to the vehicle controller 2, the vehicle controller 2 transmits the control command to the motor controller 3, and the motor controller 3 controls the headlight adjustment mechanism 4 to act.

[0030] The vehicle dynamic detection module 1 includes a tilt sensor 11 and a steering wheel angle sensor 12 .

[0031] The tilt sensor 11 detects the front and rear tilt angles of the vehicle in real time, and provides information for the vehicle controller 2 to determine the driving state of the vehicle, so as to understand whether the vehicle is going uphill or downhill.

[0032] The steering wheel angle sensor 12 detects the rotation angle and rotation speed of the steering wheel, and provides information for the vehicle controller 2 to determine the driving direction of the vehicle to understand whether the vehicle is turning.

[0033] The headlight adjustment mechanism 4 includes a vehicle headlight 41, a vertical angle adjustment component 43, and a lateral angle adjustment component 45. The vertical and lateral angles of the vehicle headlight 41 are adjusted by the vertical angle adjustment component 43 and the lateral angle adjustment component 45, so as to adjust the light angle when the vehicle turns and goes uphill or downhill.

[0034] The lateral angle adjustment assembly 45 includes a second shell 451, and the upper end surface of the second shell 451 is rotatably connected to the connecting frame 44. The vertical angle adjustment assembly 43 includes a first shell 431, and the first shell 431 is fixedly connected to the inner side of the connecting frame 44. The rear end of the automobile headlight 41 is fixedly connected to the connecting shaft 42, and the rear end of the connecting shaft 42 is rotatably connected to the connecting frame 44.

[0035] The first housing 431 is internally rotatably connected with a first half worm gear 433 and a first worm 434 which are meshed with each other. The shaft end of the first half worm gear 433 is fixedly connected to the connecting shaft 42. The upper end of the first housing 431 is fixedly connected with a first stepper motor 432. The output end of the first stepper motor 432 is fixedly connected to the first worm 434. When the vertical angle adjustment assembly 43 is in use, the first half worm gear 433 is driven by the first stepper motor 432 to change its angle, thereby adjusting the vertical angle of the automobile headlight 41.

[0036] The second housing 451 is internally rotatably connected with a second half worm gear 453 and a second worm 454 which are meshed with each other. The shaft end of the second half worm gear 453 is fixedly connected to the connecting frame 44. The upper end of the second housing 451 is fixedly connected with a second stepper motor 452. The output end of the second stepper motor 452 is fixedly connected to the second worm 454. When the lateral angle adjustment component 45 is in use, the second stepper motor 452 drives the second worm 454 to rotate, thereby driving the second half worm gear 453 to change its angle, thereby adjusting the lateral angle of the car headlight 41.

[0037] It also includes a headlight position detection module 5, which detects the angle of the car headlight 41 and feeds it back to the vehicle controller 2. The headlight position detection module 5 includes a lateral angle sensor 51 and a vertical angle sensor 52. The lateral angle sensor 51 detects the lateral rotation angle of the car headlight 41, and the vertical angle sensor 52 detects the vertical rotation angle of the car headlight 41. By setting the headlight position detection module 5, the vehicle controller 2 can understand the actual position of the car headlight 41 in real time, so that timely correction can be made when deviation occurs.

[0038] The lower end of the first shell 431 is rotatably connected with a guide ball 435, and the upper end surface of the second shell 451 is provided with an arc-shaped guide groove 455, and the guide ball 435 is slidably connected to the arc-shaped guide groove 455. By arranging the guide ball 435 and the arc-shaped guide groove 455, when the vertical angle adjustment component 43 is rotated, the guide ball 435 can rotate along the arc-shaped guide groove 455, so that the first shell 431 can rotate stably.

[0039] Working principle: When in use, the tilt sensor 11 detects the front and rear tilt angles of the car in real time, and provides information for the vehicle controller 2 to determine the driving state of the car, so as to determine whether the car is going uphill or downhill. The steering wheel angle sensor 12 detects the rotation angle and rotation speed of the steering wheel, and provides information for the vehicle controller 2 to determine the driving direction of the car, so as to understand whether the car is turning. After the dynamics of the car change, the car dynamic detection module 1 transmits the information to the vehicle controller 2, and the vehicle controller 2 transmits the control command motor controller 3, and the motor controller 3 controls the headlight adjustment mechanism 4 to act. Specifically, when the car goes uphill, the vertical angle adjustment component 43 of the headlight adjustment mechanism 4 drives the illumination angle of the car headlight 41 to adjust downward, thereby reducing the light illumination angle and avoiding dazzling oncoming vehicles. When going downhill, the illumination angle of the car headlight 41 is driven to adjust upward, thereby increasing the illumination distance and improving the driver's field of vision. When the car turns, the lateral angle adjustment component 45 drives the car headlight to adjust the angle in the turning direction, so that the light can better illuminate the inside of the curve, reduce the visual blind spot, and thus improve driving safety.
