The control module is connected with an inclination sensor for detecting the pitch angle of the vehicle in the vertical direction.

The utility model has the advantages of: intelligently adjust the angle of the intelligent headlight automatically according to signals such as the speed of the vehicle, the steering wheel angle, and the distance between incoming vehicles, improve the lighting conditions of driving, and significantly increase the driving safety of driving at night and in complex road conditions; Modernized control mode, low energy consumption, safe and reliable; simple structure, built-in installation, low manufacturing cost.

Description of drawings

The following is a brief description of the contents expressed in the accompanying drawings of the utility model specification and the marks in the figures:

Fig. 1 is a structural block diagram of the control system of the intelligent headlight in the embodiment of the utility model.

Detailed ways

The specific implementation of the present utility model will be described in further detail below through the description of the best embodiment with reference to the accompanying drawings.

As shown in Figure 1, a control system for a car's front smart headlights includes a control module, a smart headlight, a photosensitive sensor, a vehicle speed sensor, a steering wheel angle sensor, and a light adjustment motor. The vehicle speed sensor is used to collect vehicle speed information, and the steering wheel The angle sensor is used to collect the rotation angle of the steering wheel. The vehicle speed sensor and the steering wheel angle sensor are respectively connected to the control module to transmit the vehicle speed information and rotation angle information to the control module. After processing and analyzing the rotation angle information and vehicle speed information, the control module adjusts the motor through the lights Control the adjustment of the irradiation angle of the intelligent headlight.

The photosensitive sensor is arranged outside the car and is used to detect the light environment of the car. It is connected to the control module. When the ambient light is weak, the control module controls the automatic opening of the intelligent headlight by sending a driving signal. In order to save cost to realize this solution, the control module can adopt the vehicle body controller BCM.

The front intelligent headlights are divided into left headlights and right headlights, and the corresponding headlight adjustment motors are divided into left headlight adjustment motors and right headlight adjustment motors. Both the left headlight adjustment motor and the right headlight adjustment motor include a horizontal adjustment motor and a vertical adjustment motor to complete the left and right adjustment of the car lights in the horizontal direction, so as to realize the left and right adjustment of the light, and adapt to the light following changes when turning and changing lanes . The vertical adjustment motor enables the adjustment of the light angle when the car is going uphill or downhill. The specific implementation manner of adjusting the irradiation angle of the vehicle light by the vehicle light adjusting motor can be realized by using various mechanical structures in the prior art, which are not specifically limited here.

A distance measuring sensor is installed on the front of the car to detect the distance of the vehicle coming. When the distance of the vehicle coming is less than the set distance, adjust the vertical adjustment motor to adjust the lights downward in the vertical direction to reduce the impact of the light on the car. In the case of car interference, when the distance measuring sensor cannot detect the oncoming vehicle or the oncoming vehicle is far away, the vertical adjustment motor can be used to adjust the headlights in the vertical direction, so that the distance ahead of the lights is farther and the field of vision is wider. . As for adjusting the vertical adjustment motor when the set distance of the oncoming vehicle is less than the set value, the set distance here can be set according to specific conditions, and is not specifically limited here.

In order to adapt to the adjustment of the light angle when going uphill and downhill, an inclination sensor connection for detecting the vertical pitch angle of the car is provided here. The inclination sensor detects the pitch angle data of the car in the vertical direction due to uphill and downhill, and transmits it to the control module. When going uphill or downhill, the field of view distance is adjusted by the numerical value adjustment motor in the vertical direction, reducing the on-boarding of bridges, etc. Visibility problems on downhill roads.

Apparently, the specific implementation of the utility model is not limited by the above methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the present invention, they all fall within the protection scope of the present invention.
