Automobile signal lamp luminous intensity automatic control system and control method

Abstract

The invention discloses an automobile signal lamp luminous intensity automatic control system and control method. The system comprises an environment information acquisition module, a vehicle state acquisition module, a data processing module and a signal lamp driving module. The method comprises the following steps: acquiring brightness information and vehicle speed information of the current environment of a vehicle through an environment information acquisition module and a vehicle state acquisition module; determining a light-emitting target brightness value of the vehicle signal lamp based on a light-emitting intensity control strategy of the vehicle signal lamp in the data processing module; and enabling the data processing module to send a control signal to the signal lamp driving module according to the automobile signal lamp light-emitting target brightness value to automatically adjust the automobile signal lamp light-emitting intensity. According to the control system and the control method, the luminous intensity of the automobile signal lamp is automatically set by recognizing the environment where the automobile is located, coordination of the luminous intensity of the automobile signal lamp, the automobile speed and the brightness of the surrounding environment is achieved, and the driving and riding safety is further improved.

Description

technical field [0001] The invention belongs to the technical field of automobile signal lamp control, and in particular relates to an automatic control system and control method for the luminous intensity of an automobile signal lamp. Background technique [0002] Car lights refer to various traffic lights installed on cars to ensure safe driving. Among them, they are divided into: lighting lights and signal lights according to their functions. [0003] Signal lights enable other road users at a distance to clearly recognize the light signal. The lamp parameters related to this include luminous intensity, luminous area, beam spread angle and light color. In order to easily identify light signals at night with a dark background, for signal lights that are only used at night, such as position lights, marker lights, and parking lights, the luminous intensity is usually only between a few candela to tens of candela. For signal lights used day and night, such as turn signals, ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the GB 5920-2019 national mandatory standard stipulates the technical requirements for the light distribution performance of front position lights, rear position lights, position marker lights and brake lights of motor vehicles and trailers, but it does not affect the light intensity. The technical requirements stipulate the light intensity range of signal lights, but there is a lack of specific light intensity values ​​set for different external environments, and it is impossible to adjust the corresponding signal light intensity as the external environment and vehicle speed change.

[0005] Under actual road conditions, the luminous intensity of car signal lights should be coordinated with the speed of the vehicle and the light and shade of the surrounding environment. It is not conducive to safety if it is close to the upper limit of the standard. For example, under night driving conditions, when the rear car and the front car stop at the same time to wait for the signal light, or when the distance between the rear car and the front car is relatively close, if the signal light intensity of the front car If it is too high, it is very easy to cause an impact on the vision of the driver behind, making the driver dizzy, and there is a great potential safety hazard
