Description

Technical Field

[0001] This application relates to the field of front position light technology, and in particular to a front position light system and control method, storage medium and electronic device. Background Technology

[0002] To improve the vehicle's appearance and width indication, a continuous front position light is used. A continuous light typically cannot meet the light distribution requirements of a front position light on its own; it relies on the left and right headlights on either side. According to regulations, if any light source in the front position light fails, the remaining light source must still meet the light distribution requirements; otherwise, both must be extinguished. Therefore, when the continuous light works in conjunction with the left and right headlights as front position lights, the continuous light must be linked to the control of the left and right headlights.

[0003] Currently, to achieve coordinated control of the continuous light strip with the left and right headlights, an interface is typically added to the vehicle controller to connect to the continuous light strip. The vehicle controller then controls the illumination of the continuous light strip after confirming the working status of the left and right headlights. This method requires adjustments to the hardware interface of the vehicle controller and the addition of connecting wiring, which not only increases costs but also makes the wiring more complex. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of the prior art where direct control of the through lights by the whole vehicle requires the addition of interfaces and wiring, and to provide a front position light system and control method, storage medium and electronic equipment.

[0007] The first controller is electrically connected to the third lamp and is used to output a first signal to the third lamp;

[0008] The second controller is electrically connected to the third lamp and is used to output a second signal to the third lamp. The third lamp lights up when it receives the first signal and the second signal.

[0009] Furthermore, the first signal is a drive current, and the second signal is a drive signal.

[0010] Furthermore, the third lamp includes a lamp body and a switching circuit;

[0011] The first controller, the switching circuit, and the lamp body are connected in series and electrically connected to the negative terminal of the power supply.

[0016] The technical solution of this application also provides a control method for the front position light system as described above, including...

[0017] In response to the command to turn on the front position lights, the vehicle controller sends a first control command to the first controller and a second control command to the second controller;

[0018] The first control command includes a first light on / off command and a third light on / off command. The first controller controls the first light to turn on or off according to the first light on / off command, and outputs a first signal to the third light according to the third light on / off command.

[0019] The second control command includes a second light on / off command and a third light on / off command. The second controller controls the second light to turn on or off according to the second light on / off command, and simultaneously outputs a second signal to the third light according to the third light on / off command.

[0020] Furthermore, when the third light on / off command includes a gradual timing sequence:

[0021] The first controller outputs a first signal to the third lamp and controls the magnitude of the first signal according to the gradual timing sequence;

[0022] The second controller outputs a second signal to the third lamp.

[0023] Furthermore, when the third light on / off command includes a flashing timing sequence:

[0024] The first controller outputs a first signal to the third lamp interval according to the flashing sequence;

[0025] The second controller outputs a second signal to the third lamp interval according to the flashing sequence, and the first signal and the second signal are output synchronously.

[0026] Furthermore, the third light on / off command includes a flashing timing sequence, and each flashing timing sequence includes a gradient timing sequence:

[0027] The first controller outputs a first signal to the third lamp interval according to the flashing timing, and controls the magnitude of the output first signal according to the gradual change timing;

[0028] The second controller outputs a second signal to the third lamp interval according to the flashing sequence.

[0043] Front position light system:

[0044] The front position light system in the embodiments of this application, such as Figure 1 As shown, it includes a vehicle controller 04, a first light 01, a second light 02, and a third light 03 located between the first light 01 and the second light 02;

[0045] The first light 01 is equipped with a first controller 11, the second light 02 is equipped with a second controller 21, and the vehicle controller 04 is electrically connected to the first controller 11 and the second controller 21;

[0046] The first controller 11 is electrically connected to the third lamp 03 and is used to input a first signal to the third lamp 03;

[0047] The second controller 21 is electrically connected to the third lamp 03 and is used to input a second signal to the third lamp 03. The third lamp lights up when it receives the first signal and the second signal.

[0048] Specifically, the first light 01 and the second light 02 can be the left headlight and the right headlight of the vehicle, respectively, and the third light 03 is a through-type center light.

[0049] The first controller 11 is located in the first lamp 01. The first controller 11 sends a driving current and a driving signal to the lamp body in the first lamp 01 according to the control signal from the vehicle controller 04, thereby controlling the start / stop and brightness of the first lamp 01. Similarly, the second controller 21 is located in the second lamp 02. The second controller 21 sends a driving current and a driving signal to the lamp body in the second lamp 02 according to the control signal from the vehicle controller 04, thereby controlling the start / stop and brightness of the second lamp 02. The internal circuit structure of the first lamp 01 and the second lamp 02 is not an improvement of this invention; reference can be made to the existing vehicle lamp structure, and it will not be described in detail here.

[0050] In this application, the third lamp 03 is controlled by the first controller 11 and the second controller 21. The third lamp 03 is provided with two interfaces that are connected to the first controller 11 and the second controller 21 respectively. The vehicle controller 04 controls the first lamp 01, the second lamp 02 and the third lamp 03 simultaneously by sending instructions to the first controller 11 and the second controller 21. There is no direct connection interface between the third lamp 03 and the vehicle controller 04. Only the connection circuit needs to be added to the first lamp 01 and the second lamp 02, which avoids the layout of long-distance wiring harnesses, reduces costs and saves layout space.

[0051] The first controller 11 is used to input a first signal to the third lamp 03, and the second controller 21 is used to input a second signal to the third lamp 03. The first signal is a variable signal, and the second signal is a fixed signal. The first signal and the second signal control the brightness and on / off state of the third lamp 03, respectively. The third lamp 03 lights up when it receives the variable signal and the fixed signal.

[0052] As an example, the first signal is the driving current, and the second signal is the driving signal. The driving current supplies power to the third lamp 03. The larger the driving current, the brighter the third lamp 03. The driving signal provides a switching signal to the third lamp 03, which can be a PWM signal. The circuit can only turn on the third lamp 03 after receiving the driving signal.

[0053] In this embodiment, the third lamp 03 illuminates only when the first signal and the second signal are received simultaneously. Therefore, both the first controller 11 and the second controller 21 can control the third lamp 03 to turn off independently, and can turn off the third lamp 03 at the same time as the first lamp 01 or the second lamp 02 turns off. Compared with the prior art where the third lamp 03 is controlled to turn off by the vehicle controller 04, it has a faster response speed to ensure compliance with regulatory requirements.

[0054] In one embodiment, such as Figure 2 As shown, the third lamp 03 includes a lamp body 31 and a switching circuit 32;

[0055] The first controller 11, the switch circuit 32, and the lamp body 31 are connected in series and electrically connected to the negative terminal of the power supply. The second controller 21 is electrically connected to the switch circuit 32 and is used to control the on and off of the switch circuit 32.

[0056] Specifically, the drive current output by the first controller 11 flows to the negative terminal of the power supply after passing through the switching circuit 32 and the lamp body 31, thus forming a current loop. The series connection order of the switching circuit 32 and the lamp body 31 is not limited, and the lamp body 31 can be an LED.

[0057] The second controller 21 is electrically connected to the switching circuit 32 and is used to input drive current to the switching circuit 32. The switching circuit 32 can be a MOS switching circuit, and the switching circuit 32 is turned on when the drive current is input.

[0058] In this embodiment of the application, when the first controller 11 outputs a driving current and the second controller 21 outputs a driving signal, the circuit containing the lamp body 31 and the switch circuit 32 is energized, and the lamp body 31 lights up.

[0059] In one embodiment, such as Figure 2 As shown, the third lamp 03 also includes a first filter circuit 33, a second filter circuit 34, and a constant current circuit 35;

[0060] The first controller 11 is connected in series with the first filter circuit 33, and then in series with the switch circuit 32 and the lamp body 31;

[0061] The second controller 21 is connected in series with the second filter circuit 34 and then electrically connected to the switching circuit 32;

[0062] The constant current circuit 35 is connected in series in the loop between the first controller 11 and the lamp body 31.

[0063] Specifically, the first filter circuit 33 filters the drive current output by the first controller 11, reducing the ripple coefficient of the rectified output voltage, improving the stability of the drive current, and protecting the lamp body load. The constant current circuit 35 is connected in series between the first controller 11 and the lamp body 31. The constant current circuit 35 maintains a constant current before the current flows into the lamp body 31, thus providing a stable current to the lamp body 31. As an example, such as... Figure 2 As shown, the first filter circuit 33, the switching circuit 32, the constant current circuit 35, and the lamp body 31 are connected in series.

[0064] The second filter circuit 34 is used to filter the drive signal output by the second controller 21, remove interference signals, and improve the stability of the drive signal.

[0065] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0066] Control method of front position light system:

[0067] The control method for the front position light system in this application embodiment is applied to the front position light system in any of the foregoing embodiments, and the control method includes...

[0068] In response to the command to turn on the front position lights, the vehicle controller sends a first control command to the first controller and a second control command to the second controller;

[0069] The first control command includes a first light on / off command and a third light on / off command. The first controller controls the first light to turn on or off according to the first light on / off command, and outputs a first signal to the third light according to the third light on / off command.

[0070] The second control command includes the second light on / off command and the third light on / off command. The second controller controls the second light to turn on or off according to the second light on / off command, and at the same time outputs a second signal to the third light according to the third light on / off command.

[0071] Specifically, when the vehicle controller receives a command to turn on the front position lights, it generates a first control command and a second control command based on the type of command, and sends the first and second control commands to the first controller and the second controller, respectively. For different types of front position light turn-on commands, the first, second, and third lights correspond to different on / off timings and brightness changes.

[0072] The first control command is used to control the on / off state of the first and third lights, and the second control command is used to control the on / off state of the second and third lights.

[0073] After receiving the first control command, the first controller controls the first lamp to turn on or off according to the first lamp on / off command. At the same time, it generates a third lamp first signal according to the third lamp on / off command and outputs it to the third lamp. The current change of the third lamp first signal is determined according to the brightness change rule in the third lamp on / off command.

[0074] After receiving the second control command, the second controller controls the second light to turn on or off according to the second light on / off command. At the same time, it generates a third light second signal according to the third light on / off command and outputs it to the third light. The third light second signal is determined according to the on / off timing rules in the third light on / off command.

[0075] In this embodiment, when the vehicle controller receives the command to turn on the front position lights, it sends a first control command and a second control command to the first controller and the second controller, respectively. The first controller and the second controller control the third light. The vehicle controller only needs to send two commands to control all three lights. The first controller controls the first light and the third light simultaneously, and the second controller controls the second light and the third light simultaneously. For the dynamic lighting effect of the three lights, the delay between the third light and the first and second lights can be avoided, thus improving the dynamic lighting effect of the front position lights.

[0076] In one embodiment, the third light on / off command includes a gradual timing sequence:

[0077] The first controller outputs a first signal to the third lamp and controls the magnitude of the first signal according to the gradual timing sequence;

[0078] The second controller outputs a second signal to the third lamp.

[0079] Specifically, when the brightness of the third light needs to gradually change during the lighting process, the third light's on / off command includes a gradual timing sequence. Different brightness levels correspond to different magnitudes of the first signal. The first controller generates a gradually changing first signal according to the gradual timing sequence and outputs it to the third light.

[0080] Furthermore, the third lamp requires a second signal to drive it when it is lit, regardless of its brightness. Therefore, if the third lamp's on / off command includes a gradual timing sequence, the second controller needs to continuously output a second signal to the third lamp.

[0081] In this embodiment of the application, the magnitude of the first signal is adjusted by the first controller, which enables the third lamp to light up in a gradual effect.

[0082] In one embodiment, the third light on / off command includes a flashing timing sequence:

[0083] The first controller outputs a first signal to the third lamp interval according to the flashing sequence;

[0084] The second controller outputs a second signal to the third lamp interval according to the flashing sequence, and the first signal and the second signal are output synchronously.

[0085] Specifically, when the third light needs to exhibit a flashing effect during its illumination process—that is, after a first illumination period followed by a second illumination period—the third light's on / off command includes a flashing sequence. During this time, a first signal and a second signal need to be output synchronously. Since the brightness of the third light remains constant during illumination, the output first signal remains unchanged. Therefore, the first controller outputs the first signal to the third light at intervals according to the flashing sequence, and the second controller outputs the second signal to the third light at intervals according to the flashing sequence.

[0086] In this embodiment, the third light is illuminated with a flashing effect by synchronously and intermittently outputting a first signal and a second signal by a first controller and a second controller. The first signal and the second signal are output intermittently, so the flashing effect can still be achieved even if either signal fails. For example, the third light can flash even if the first signal is continuously output and the second signal is output intermittently.

[0087] In one embodiment, the third light on / off command includes a flashing sequence, and each flashing sequence includes a gradient sequence:

[0088] The first controller outputs a first signal to the third lamp at intervals according to the flashing sequence, and controls the magnitude of the output first signal according to the gradual change sequence;

[0089] The second controller outputs a second signal to the third lamp at intervals according to the flashing sequence.

[0090] Specifically, when the third light needs to exhibit a breathing effect during its illumination process, its brightness gradually increases in the first time period, gradually decreases until it goes out in the second time period, and then cycles again after the third time period. In this case, the third light's on / off command includes a flashing sequence, and each flashing sequence includes a gradual transition sequence.

[0091] Both the second and first signals need to be output according to the flashing timing interval, and the magnitude of the first signal also needs to be adjusted according to the gradual timing during each output period.

[0092] In this embodiment, a first controller outputs a gradually changing first signal at intervals, and a second controller outputs a second signal at intervals, to achieve a breathing effect lighting of the third lamp. The interval output of both the first and second signals reduces the error rate of the breathing effect and improves the stability of the third lamp's lighting.

[0093] Depending on the needs, the control method of the front position light system in any of the above embodiments can be used to achieve different lighting effects of the front position lights. The third light can cooperate with the first and second lights to achieve different lighting effects according to the different light signals of the front position lights, such as welcome light signals, farewell light signals, etc.
