Description

Daytime running light control system

technical field

The utility model relates to the field of automobiles, in particular to an automobile daytime running light control system.

Background technique

Daytime running lights are daytime running lights installed on the front of the car body, which are lamps that make the vehicle easier to be recognized when driving in the daytime. Its function is not to enable the driver to see the road, but to let others know that a car is coming. Therefore, this lamp is not a lighting lamp, but a signal lamp. Of course, the addition of daytime running lights can make the car look cooler and more dazzling, but the biggest function of daytime running lights is not to look good, but to provide the recognition of the vehicle. Turning on headlights while driving abroad can reduce 12.4% of vehicle accidents and 26.4% of death rates in car accidents. In short, the purpose of daytime running lights is for traffic safety.

However, after installing the daytime running lights, if the daytime running lights are only used as signal lights for pedestrians to avoid, it is a bit wasteful. As part of the car light system, the daytime running lights can strengthen the signals of other lights.

Therefore, the problem of how to effectively use daytime running lights as signal strengthening lights has become one of the current technical problems that need to be solved urgently.

Utility model content

The purpose of the utility model is to provide a daytime running light control system which can effectively utilize the daytime running light.

In order to solve the technical problem of the utility model, the utility model provides a daytime running light control system, which includes a central control unit, a dimming module, a first LED constant current control module for controlling the left daytime running light, and a first LED constant current control module for controlling the right The second LED constant current control module of the side daytime running lights and the central control unit are respectively connected with the first LED constant current control module, the second LED constant current control module and the dimming module.

Wherein, the daytime running light control system further includes a left side daytime running light connected to the first LED constant current control module.

Wherein, the daytime running light control system further includes a right daytime running light connected to the second LED constant current control module.

Wherein, the dimming module adopts a PMW pulse modulation module.

Compared with the prior art, the daytime running light control system of the utility model effectively utilizes the function of the daytime running light, besides having the function of reminding pedestrians to avoid, it can also enhance the function of the turn signal.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in FIG. 1 , in the present utility model, the daytime running lights include a left daytime running light arranged on the left side of the vehicle and a right daytime running light arranged on the right side of the car. The daytime running light control system includes a central control unit, a first LED constant current control module, a second LED constant current control module and a dimming module. The first LED constant current control module and the second LED constant current control module are respectively connected with the left daytime running light and the right daytime running light, and are respectively used to control the light emission of the left daytime running light and the right daytime running light. The dimming module is used to control the brightness of the daytime running light on the left and the daytime running light on the right. The central control unit is respectively connected with the first LED constant current control module, the second LED constant current control module and the dimming module, and is used to send control signals to the first LED constant current control module, the second LED constant current control module and the dimming module. The light module controls the lighting state of the daytime running lights. The central control unit respectively detects the ACC signal, the turn signal and the small light status signal for real-time monitoring, so as to send control signals to the first LED constant current control module, the second LED constant current control module and the dimming module to control the lighting of the daytime running lights state. The dimming module uses a PMW pulse modulation module to ensure that the current of the lamp is consistent every time it is turned on, so that the brightness is consistent and flickering is avoided.

As shown in Figure 2, the control process of the above-mentioned daytime running light control system is as follows:

After the car is started, the central processing unit detects the ACC signal, and the daytime running lights are on;

Continue to detect the ACC signal, if the ACC signal is low, it means that the car stops starting, and the daytime running light turns off after 15 seconds;

If the ACC signal is high, continue to detect the turn signal; if there is a turn signal, control the daytime running lights to change together with the turn signal to enhance the signal of the turn signal; if there is no turn signal, keep the daytime running light on normally;

Detect whether the small light is turned on, if it is turned on, reduce the brightness of the daytime running light and reduce the energy consumption of the car; if the small light is not turned on, continue to keep the daytime running light on normally.

Compared with the prior art, the daytime running light control system of the utility model effectively utilizes the function of the daytime running light, besides having the function of reminding pedestrians to avoid, it can also enhance the function of the turn signal.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the utility model belongs, on the premise of not departing from the concept of the utility model, some simple deduction or replacement can also be made, which should be regarded as belonging to the protection scope of the utility model.
