A light control method, a light control system, and a vehicle

Abstract

This invention provides a vehicle lighting control method, a lighting control system, and a vehicle, relating to the field of vehicle lighting control technology. In response to a trigger command indicating that the vehicle's rest mode is activated, this invention sends a shutdown setting signal or an automatic setting signal to the vehicle's lighting switch device; subsequently, it receives a shutdown request signal or an automatic request signal from the lighting switch device and controls the opening and closing of the vehicle's exterior lights based on the shutdown request signal or the automatic request signal. This technical solution, when the vehicle is in rest mode, first controls the state of the lighting switch device, and then controls the opening and closing of the vehicle's exterior lights after receiving the state signal from the lighting switch device, rather than directly controlling the opening and closing of the vehicle's exterior lights based on the vehicle's rest mode. This setup ensures that the state of the lighting switch device is consistent with the state of the vehicle's exterior lights, enabling intelligent control of the vehicle's exterior light status based on the activation or deactivation of the rest mode.

Description

Technical Field

[0001] This invention relates to the field of vehicle lighting control technology, and in particular to a vehicle lighting control method, a lighting control system, and a vehicle. Background Technology

[0002] With the development of automotive technology, cars are becoming increasingly intelligent. Cars are no longer just a means of transportation, but also a second space for users to rest and relax. Current vehicles have headlight switches located on the central control screen via a soft switch, which allows for convenient and intelligent headlight shut-off when the rest mode is activated. However, most vehicles on the market with mechanical switches do not automatically shut off headlights and other power-consuming devices in rest mode. Users need to manually activate the mechanical switch to turn off the lights. After resting, users may forget that they turned off the lights and not remember to turn the mechanical switch back on, or the mechanical switch status may be inconsistent with the actual headlight status after the lights are turned off in rest mode. For example, the actual headlights may be on, while the mechanical switch may be off. Summary of the Invention

[0003] One objective of the first aspect of this invention is to provide a vehicle lighting control method that solves the technical problem in the prior art where the state of the mechanical switch is inconsistent with the actual state of the vehicle's exterior lights.

[0004] Another objective of the first aspect of this invention is to save development costs.

[0005] The second aspect of this invention is to provide a vehicle lighting control system.

[0006] The third aspect of the present invention is to provide a vehicle having the above-described lighting control system.

[0007] According to a first aspect of the present invention, the present invention provides a method for controlling the lights of a vehicle, comprising the following steps:

[0008] In response to the trigger command to activate the vehicle's rest mode, a turn-off setting signal or an automatic setting signal is sent to the vehicle's light switch device.

[0009] The system receives a shutdown request signal or an automatic request signal from the light switch device, and controls the opening and closing of the vehicle's exterior lights according to the shutdown request signal or the automatic request signal. The shutdown request signal is generated by the light switch device after receiving and executing the shutdown setting signal, and the automatic request signal is generated by the light switch device after receiving and executing the automatic setting signal.

[0010] Optionally, the following steps are also included:

[0011] In response to the trigger command to turn off the vehicle rest mode, an automatic set signal is sent to the light switch device;

[0012] The system receives an automatic request signal from the light switch device and controls the opening and closing of the vehicle's exterior lights according to the automatic request signal.

[0013] Optionally, the step of sending an off setting signal or an automatic setting signal to the vehicle's light switch device in response to a trigger command to activate the vehicle's rest mode specifically includes the following steps:

[0014] In response to a trigger command to activate the vehicle's rest mode, the vehicle receives gear information, including P, N, R, and D gears.

[0015] When the vehicle is in P or N gear, a turn-off signal is sent to the light switch device.

[0016] Optionally, the step of receiving the vehicle's gear information in response to a trigger command to activate the vehicle's rest mode includes the following steps:

[0017] When the vehicle's gear is switched from R or D to P or N, a shutdown setting signal is sent to the light switch device.

[0018] Optionally, the step of receiving the vehicle's gear information in response to a trigger command to activate the vehicle's rest mode further includes the following steps:

[0019] When the vehicle's gear is shifted from P or N to R or D, an automatic setting signal is sent to the light switch device.

[0020] Optionally, the step of sending an off setting signal or an automatic setting signal to the vehicle's light switch device in response to a trigger command to activate the vehicle's rest mode further includes the following steps:

[0021] In response to a trigger command that activates the vehicle rest mode, the vehicle's speed information is received;

[0022] When the vehicle's speed exceeds a preset speed value, an automatic set signal is sent to the light switch device.

[0023] Optionally, the following steps are also included:

[0024] After sending a shutdown setting signal or an automatic setting signal to the light switch device, the state of the light switch device remains unchanged for a preset time.

[0025] Optionally, the step of receiving an automatic request signal sent by the light switch device and controlling the opening and closing of the vehicle's exterior lights according to the automatic request signal specifically includes the following steps:

[0026] Upon receiving an automatic request signal from the light switch device, the system acquires external light information.

[0027] The vehicle's exterior lights are turned off when the ambient light outside the vehicle is less than a preset light value, and turned on when the ambient light outside the vehicle is greater than or equal to the preset light value.

[0028] According to a second aspect of the present invention, the present invention also provides a vehicle lighting control system, comprising:

[0029] The control module includes a memory and a processor. The memory stores a calculation program, which, when executed by the processor, is used to implement the above-described lighting control method.

[0030] According to a third aspect of the present invention, the present invention also provides a vehicle including the above-described lighting control system.

[0031] In this invention, in response to a trigger command indicating that the vehicle's rest mode is activated, a shutdown setting signal or an automatic setting signal is sent to the vehicle's light switch device. Then, a shutdown request signal or an automatic request signal from the light switch device is received, and the opening and closing of the vehicle's exterior lights is controlled according to the shutdown request signal or the automatic request signal. This technical solution, when the vehicle is in rest mode, first controls the state of the light switch device, and then controls the opening and closing of the vehicle's exterior lights after receiving the state signal from the light switch device, rather than directly controlling the opening and closing of the vehicle's exterior lights based on the vehicle's rest mode. This setup ensures that the state of the light switch device is consistent with the state of the vehicle's exterior lights, enabling intelligent control of the vehicle's exterior light state based on the opening or closing of the rest mode, and ensuring that the light switch device functions normally without being affected by the intelligent opening and closing of the vehicle's exterior lights.

[0032] Furthermore, this invention does not require modification to the connection relationship between the light switching device, the vehicle exterior lights, and the control module, and does not require modification to mature software models such as the vehicle exterior light activation logic. The vehicle exterior light activation logic still depends on the light switching device request, and the addition of new functions and logic does not affect the original mature model, thereby saving development costs.

[0033] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0042] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] Figure 1 This is a schematic flowchart of a vehicle lighting control method according to an embodiment of the present invention. Figure 1 As shown, in one specific embodiment, the vehicle lighting control method includes the following steps:

[0044] Step S100: In response to the trigger command to turn on the vehicle rest mode, send an off setting signal or an automatic setting signal to the vehicle's light switch device.

[0045] Step S200: Receive an off request signal or an automatic request signal from the light switch device, and control the opening and closing of the vehicle's exterior lights according to the off request signal or the automatic request signal. The off request signal is generated after the light switch device receives and executes the off set signal, and the automatic request signal is generated after the light switch device receives and executes the automatic set signal. Here, the off set signal and the off request signal can be understood as the OFF set signal and the OFF request signal, respectively, and the automatic set signal and the automatic request signal can be understood as the AUTO set signal and the AUTO request signal, respectively.

[0046] In this embodiment, when the vehicle is in rest mode, the status of the light switch device is controlled first, and then the status signal of the light switch device is received before the vehicle's exterior lights are turned on or off. Instead of directly controlling the vehicle's exterior lights based on the vehicle's rest mode, this setting ensures that the status of the light switch device is consistent with that of the vehicle's exterior lights. It can intelligently control the lighting status of the vehicle's exterior lights based on the opening or closing of the rest mode, and ensure that the light switch device can be used normally without being affected by the intelligent opening and closing of the vehicle's exterior lights.

[0047] In this embodiment, the light switch is a mechanical switch, which allows the user to control the vehicle's exterior lights. This embodiment achieves intelligent control of the mechanical switch while ensuring that its original functions remain unaffected.

[0048] Figure 2 This is a schematic flowchart of a vehicle lighting control method according to another embodiment of the present invention.

[0049] like Figure 2 As shown, in this embodiment, the lighting control method further includes the following steps:

[0050] In step S300, in response to the trigger command to turn off the vehicle rest mode, an automatic setting signal is sent to the light switch device;

[0051] In step S400, an automatic request signal is received from the light switch device, and the vehicle's exterior lights are controlled to turn on or off according to the automatic request signal. It should be noted that steps S300 and S100 are not sequential.

[0052] This embodiment sends signals to the light switch device when the vehicle's rest mode is turned on and off, achieving intelligent control of the mechanical switch. The vehicle's exterior lights are then controlled only after receiving the signal from the light switch device. In existing technology, mechanical switches can only switch states when manually adjusted by the user, while this embodiment can also switch the state of the mechanical switch automatically through the control module, achieving intelligent control.

[0053] Figure 3This is a schematic flowchart of a vehicle lighting control method according to yet another embodiment of the present invention.

[0054] like Figure 3 As shown, in this embodiment, step S100 specifically includes the following steps:

[0055] Step S110: In response to the trigger command for activating the vehicle rest mode, receive the vehicle's gear information, including P, N, R and D gears.

[0056] Step S120: Selectively send a shutdown setting signal or an automatic setting signal to the light switch device according to the gear position information.

[0057] In this embodiment, step S120 includes the following steps:

[0058] Step S121: When the vehicle is in P or N gear, send an off setting signal to the light switch device;

[0059] Step S122: When the vehicle's gear is switched from R or D to P or N, a turn-off setting signal is sent to the light switch device;

[0060] Step S123: When the vehicle's gear is switched from P or N to R or D, an automatic setting signal is sent to the light switch device.

[0061] Step S124: When the vehicle is in R or D gear, an automatic set signal is sent to the light switch device. It should be noted that steps S121, S122, S123, and S124 are not sequential. That is, in this embodiment, the off set signal is sent to the light switch device only when the vehicle is in rest mode and in P or D gear, indicating that the vehicle is truly in rest mode. Upon receiving the off request signal from the light switch device, the vehicle's exterior lights are directly turned off. If the vehicle is in R or D gear, even if the vehicle is in rest mode, sending an automatic set signal to the light switch device does not directly turn off the exterior lights; instead, the exterior lights are controlled according to the automatic mode in the light switch device.

[0062] In steps S122 and S123, the gear shifting is done manually, meaning it is done by the user, and is primarily based on the user's operation.

[0063] In this embodiment, if the light switch receives and executes the automatic set signal, and the user presses the light switch again, the light switch switches to the off mode, which is equivalent to receiving the off set signal. The control module then executes the corresponding action according to the off request signal of the light switch.

[0064] In existing technology, vehicle lights are controlled via a large-screen soft switch, which can intelligently turn off during leisure and entertainment activities. However, switching the light status while driving requires navigating to the soft switch on the central control screen, resulting in multiple operational steps that are inconvenient and compromise driving safety. This embodiment, on the other hand, uses a mechanical switch, allowing users to control the lights simply by pressing it, which is much more convenient.

[0065] In this embodiment, step S100 further includes the following steps:

[0066] Step 1: In response to the trigger command for activating the vehicle's rest mode, receive the vehicle's speed information;

[0067] Step two: When the vehicle speed exceeds a preset speed value, an automatic set signal is sent to the light switch device. It should be noted that there is no sequential relationship between step one and step S110. When the vehicle rest mode is activated, both the vehicle's gear position and speed information need to be obtained. Only when both the vehicle's gear position and speed meet certain conditions will a turn-off set signal be sent to the light switch device, indicating that the vehicle is truly in rest mode. Here, the certain conditions refer to the vehicle being in P or D gear and the vehicle speed being less than or equal to a preset speed value. The preset speed value can be set to 5 km / h; in other embodiments, the preset speed value can be set according to other design requirements.

[0068] In this embodiment, the lighting control method further includes the following steps:

[0069] After sending an off set signal or an auto-set signal to the light switch device, the state of the light switch device remains unchanged for a preset time. That is, after receiving and executing the off set signal, if the light switch device receives an auto-set signal within the preset time, its state remains unchanged. Here, the preset time can be set to 200ms; in other embodiments, the preset time can also be set according to specific design requirements. After the preset time, if there is another need to switch the state of the light switch device, the current light action state is executed according to the request after the light switch device switches.

[0070] In this embodiment, step S400 specifically includes the following steps:

[0071] Step 3: Upon receiving an automatic request signal from the light switch device, acquire information about the ambient light outside the vehicle;

[0072] Step four: When the outside light level is lower than a preset light value, the vehicle's exterior lights are turned off; when the outside light level is greater than or equal to the preset light value, the exterior lights are turned on. This can be understood as the control module controlling the exterior lights based on the outside light level when the light switch is in automatic mode. During the day, the exterior lights can be turned off, and at night, they can be turned on. The light information is specifically obtained from the rain and light sensor signal.

[0073] Compared with existing mechanical switches, this embodiment can control the vehicle's exterior lights when intelligent scenarios are required. It can intelligently control the light status by turning it on or off according to the rest mode. The control device does not need to change the mature software model such as the light switch logic. The turning the lights on and off still depends on the switch request. The new functions and logic do not affect the original mature model, and can meet the needs of convenient operation of mechanical switches.

[0074] Figure 4 This is a schematic connection block diagram of a vehicle lighting control system 100 according to an embodiment of the present invention. Figure 4 As shown, in a specific embodiment, the vehicle's lighting control system 100 includes a control module 10. The control module 10 includes a memory 11 and a processor 12. The memory 11 stores a calculation program, which, when executed by the processor, is used to implement the aforementioned lighting control method. The processor 12 can be a central processing unit (CPU), a digital processing unit, etc. The processor 12 sends and receives data via a communication interface. The memory 11 is used to store the program executed by the processor 12. The memory 11 can be any medium capable of carrying or storing desired program code in the form of instructions or data structures, and accessible by a computer; it can also be a combination of multiple memories 11. The aforementioned calculation program can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded to a computer or external storage device via a network (e.g., the Internet, a local area network, a wide area network, and / or a wireless network). Here, the control module 10 can be a vehicle body controller.

[0075] For the purposes of this embodiment, a "computer-readable medium" can be any means that can contain, store, communicate, propagate, or transmit a program for use by or in conjunction with an instruction execution system, apparatus, or device. More specific examples of computer-readable media (a non-exhaustive list) include: an electrical connection (electronic device) having one or more wires, a portable computer disk drive (magnetic device), random access memory (RAM), read-only memory (ROM), erasable and editable read-only memory (EPROM or flash memory), fiber optic devices, and portable optical disc read-only memory (CDROM). Furthermore, a computer-readable medium can even be paper or other suitable media on which the program can be printed, since the program can be obtained electronically, for example, by optically scanning the paper or other medium, followed by editing, interpreting, or otherwise processing as necessary, and then stored in computer memory 11.

[0076] Figure 5 This is a schematic connection block diagram of a vehicle lighting control system 100 according to another embodiment of the present invention. Figure 5 As shown, in this embodiment, the lighting control system 100 also includes a central control screen 40, a lighting switch device 20, and vehicle exterior lights 30. The central control screen 40, the lighting switch device 20, and the vehicle exterior lights 30 are all connected to the control module 10 to realize signal transmission.

[0077] This embodiment also provides a vehicle that includes the aforementioned lighting control system 100. Details regarding the lighting control system 100 will not be provided here.

[0078] This embodiment enables intelligent control of the vehicle's exterior lights 30, avoiding driving safety risks caused by users forgetting to turn on the lights after resting. It also ensures that the actual state of the light switch device 20 is consistent with the actual state of the vehicle's exterior lights 30, preventing changes in the operating logic of the light switch device 20 when the vehicle's exterior lights 30 are intelligently controlled.

[0079] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
