Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the overall process of the system is as follows:

[0031] Step 1: Information collection. Use the vehicle speed sensor and photosensitive sensor to collect the current vehicle speed and light intensity information.

[0032] Step 2: Discrimination of the environment. The main control module (the embodiment of the present invention adopts the vehicle-mounted electronic control unit ECU to realize) analyzes and judges the information collected by the sensor and adjusts the brightness of the headlight.

[0033] Further, the step 2 is specifically as follows:

[0034] Step 2.1: Estimate the current environment of the car according to the vehicle speed, and divide it into low-speed and complex road conditions, medium-speed urban road conditions, and high-speed road conditions. Driving speed less than 30km / h is d...

Abstract

The invention discloses a brightness-adjustable car intelligent headlamp system based on the environment, and a method. The current environment of a car is preliminarily judged according to the car speed and light intensity, and the illumination brightness of the headlamp is adjusted based on the light intensity in the current environment, and the effects of energy saving and light pollution reduction are taken into account while meeting the lighting requirements. A design of the brightness-adjustable car intelligent headlamp system based on the environment is provided, and the brightness of the car lamp can be adjusted by collecting the environmental information through a sensor and judging by a master controller. The system comprises the sensor, the master controller and an actuator, thelighting brightness of the headlamp can be adjusted according to the driving state and the environmental information of the car, and energy is saved while providing a better road lighting effect fora driver.

Description

technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to an adaptive automobile headlight. Background technique [0002] With the development of the automobile industry, people put forward higher requirements for automobile safety, and the automobile lighting system has been significantly developed. Due to the single lighting mode of traditional headlights, the lighting pattern and angle cannot be automatically changed with the road alignment and surrounding environment, and the adjustment of far and low beams is also manually switched. Such a headlight system can no longer meet the requirements The lighting requirements of different road environments, lighting blind spots and glare and other adverse conditions will bring panic to drivers, easily cause driving fatigue, and lead to a serious lack of comfort and safety when driving at night. The automotive intelligent headlight system can provide a variety of lighting ranges an...
