detailed description

FIG. 1 is a schematic structural diagram of a life reminding system for an automotive lighting device according to an embodiment of the present invention. In one embodiment, as shown in FIG. 1 , the life reminding system of an automobile lighting device of the present invention may generally include a lighting device 1 , a vehicle body controller 2 and a reminder device.

The lighting device 1 is usually installed at a corresponding position on the car. At present, the lighting device 1 can have various structural forms, such as a traditional light bulb and lamp holder structure, or a structure composed of an LED lighting module, a reflector, a lampshade, and a shielding layer. However, no matter what the structure is, its light source has a rated service time, and this time is usually obtained through relevant tests. Therefore, the lighting device 1 of the present invention has its rated service life. In addition, the lighting device 1 can present a variety of types according to the installation position, the type of light emission, the intensity of the light emission, and the function, such as the daytime running light 101, the position light 102, and the brake light 103. Similarly, They all have their corresponding rated service life.

The vehicle body controller 2, on the one hand, can detect whether the lighting device 1 is turned on, for example, a corresponding sensor can be installed on the switch part of the lighting device 1 to detect the turning-on command of the lighting device 1, thereby judging whether the lighting device 1 is turned on; on the other hand, The vehicle body controller 2 can determine whether the lighting device 1 is damaged, and a corresponding sensor can be installed to detect whether the lighting device 1 emits light. Make statistics, and accumulate the use time of this turn-on with all the use time of the previous turn-on this time to obtain the total use time of the lighting device 1, and then compare the total use time with the rated service life of the lighting device 1 entered in advance Perform subtraction to obtain the remaining available time of the lighting device 1; finally, the vehicle body controller 2 can also issue a corresponding warning command when the remaining available time of the lighting device 1 is less than a predetermined threshold and/or the lighting device 1 is damaged. Wherein, the above predetermined threshold is set to 48 hours to reserve enough time for the user to replace, of course, this time can also be set to other values as required.

The reminding device is a device for reminding according to the warning instruction issued by the above-mentioned vehicle body controller 2 . The reminding device can have various kinds of reminding, such as image reminding, sound reminding, or both image and sound reminding and the like. In this embodiment, image reminders and sound reminders are included, which are more diversified, and the image reminders and sound reminders can be reminded individually or in combination, so that the reminder effect is more obvious and the applicability is stronger. Specifically, the reminding device includes a display screen 3 , which is electrically connected to the vehicle body controller 2 , and is used to visually display the warning instruction issued by the vehicle body controller 2 on the display screen 3 . And there is a display controller 5 connected to the display screen 3, the display controller 5 receives the warning instruction sent by the body controller 2 through the CAN bus of the automobile, and displays the received warning instruction on the display screen in a visual manner. 3 on. In addition, the reminding device also includes an alarm horn 4, which is electrically connected to the vehicle body controller 2, and is used to remind the vehicle body controller 2 of a warning command by sound.

In addition, it should be noted that in other alternative embodiments, the display screen 3 can be a touch display screen, through which the rated service life of the lighting device 1 can be entered into the vehicle body controller 2, and the user can also Through this display screen 3, the reminder mode of the reminder device is set as a visual mode and/or a sound mode, which is easy to operate and more humanized.

To sum up, the light device life reminder system of the present invention can remind the user that the service life of the car light device is about to run out or has been damaged, thereby reducing safety risks, reducing the chance of being punished, and making the vehicle more humane and safe. intelligent.

Fig. 2 is a flow chart of a control method of a life reminding system for an automotive lighting device according to an embodiment of the present invention. As shown in Figure 2, the control method of the present invention may specifically include the following steps:

A step 101, one or more of the plurality of lighting devices 1 sends a notification signal that the corresponding lighting device has been turned on to the vehicle body controller 2 after being turned on or receiving a turn-on command;

B step 102, after the vehicle body controller 2 receives the above notification signal, judge whether the corresponding lighting device 1 is damaged; if damaged, proceed to F step 106; if not damaged, proceed to C step 103;

C Step 103, the vehicle body controller 2 counts the usage time of the corresponding lighting device 1 after it is turned on this time, and accumulates the usage time of the current startup and all the usage times that were turned on this time, so as to obtain the lighting The total use time of the device 1 being turned on; then proceed to step D and step 104;

D step 104, the vehicle body controller 2 subtracts the total usage time of the corresponding lighting device 1 from the rated service life of the corresponding lighting device 1 entered in the vehicle body controller 2, to obtain the remaining available time of the corresponding lighting device 1; and then Carry out step E step 105;

E step 105, the vehicle body controller 2 compares the remaining available time of the corresponding lighting device 1 with a predetermined threshold, and judges whether the remaining available time is less than the predetermined threshold; if it is less, proceed to F step 106; if not, then Return to B step 102;

F Step 106, the vehicle body controller 2 sends a warning instruction to the reminder device, so that the reminder device performs a reminder. The reminding device reminds visually through the display screen 3 and/or audibly through the alarm horn 4, so that the reminding methods are more diverse and the reminding effect is more obvious.

In addition, it should be noted that, in other alternative embodiments, the control method of the life reminding system of the automobile lighting device further includes step G.

Step G, enter the rated service life of each lighting device into the vehicle body controller 2 through the display screen 3 . Especially after the user has replaced a new lighting device 1, it is more convenient and timely to enter its rated life into the vehicle body controller 2 through manual input, and the vehicle body controller 2 immediately monitors the service life of the new lighting device 1, so that The control method of the whole lighting device life reminding system is more humanized.

Similarly, in other alternative embodiments, the control method of the life reminding system of the automotive lighting device further includes step H.

Step H, setting the reminder mode of the reminder device to the visual mode and/or the sound mode through the display screen 3 . The user can freely set the reminder method according to the needs, which is more humanized, and can make the reminder effect more obvious and the applicability stronger by mixing the reminder method.

So far, those skilled in the art should appreciate that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, the disclosed embodiments of the present invention can still be used. Many other variations or modifications consistent with the principles of the invention are directly identified or derived from the content.
