[0038] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0040] If the application documents contain similar descriptions such as "first, second, third", the following explanation shall be added: In the following description, the terms "first, second, third" are used only to distinguish similar objects and do not represent a specific order of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0042] To address the problems existing in related technologies, this application provides a lighting switching method. This method is applied to an electronic device, which may be a server, mobile terminal, computer, cloud platform, etc. The lighting switching device provided in this application can achieve its functions by having the electronic device's processor call program code, which can be stored in a computer storage medium.

[0043] See Figure 1 , Figure 1 This is a flowchart of a light switching method provided in an embodiment of this application, which includes the following steps:

[0044] Step S101: Collect detection information when the vehicle's lights are in automatic mode.

[0045] Automatic mode is the opposite of manual mode. Manual mode means that the driver determines the next step to be taken based on the current or anticipated vehicle status and then performs the corresponding operation.

[0046] In some embodiments, the vehicle lights are in manual mode, meaning that the driver determines whether to switch to high beams or low beams based on the current or anticipated ambient light intensity or other vehicle operating information, and performs the operation of switching the lights to high beams or low beams.

[0047] Most vehicles on the market currently have manual lighting. This single mode relies solely on the driver's judgment and operation to switch lights, which is prone to errors and can easily lead to untimely light switching, hindering the driver's normal driving and increasing the risk of traffic accidents.

[0048] In some embodiments, the vehicle's lights are in automatic mode, that is, the vehicle obtains the current or estimated light intensity of the environment in which the vehicle is located, or other vehicle operation-related information, such as about to pass through a tunnel or there are pedestrians at a certain distance ahead, through electronic devices, and determines and executes the switching of the lights to high beam or low beam according to preset logic.

[0049] Currently, the integrated intelligent high and low beam headlights devices for vehicles in China are highly intelligent but expensive, making them affordable only for a small number of high-end cars. Furthermore, these devices are only designed and installed on vehicles currently in production, making installation difficult on already manufactured vehicles, and in some cases, retrofitting is impossible. Moreover, these devices rely on onboard radar systems, which, while providing relatively accurate data processing, are susceptible to weather conditions and lack testing for prohibited objects, potentially leading to misjudgments of pedestrians. Additionally, due to radar performance limitations, the system's reaction time has a significant delay, and its sensitivity needs improvement.

[0050] In some embodiments, the switching between the manual and automatic modes described above can be performed manually by the driver or automatically by the vehicle operating system.

[0051] In some embodiments, the automatic mode is determined by detecting the ambient light intensity, wherein the automatic mode is activated when the ambient light intensity is lower than the ambient light intensity threshold.

[0052] In some embodiments, the detection information includes, but is not limited to, vehicle operating status information, which is information related to the driver's field of vision, including, but not limited to, ambient light intensity and road gradient.

[0053] In some embodiments, the detection information may also include vehicle prediction information, such as channels on the proposed route and biometric information at a preset distance in front of the vehicle.

[0054] In the above embodiments, the detection information affects the brightness within the driver's field of vision.

[0055] In some embodiments, the acquisition and detection information is achieved through electronic devices, including but not limited to sensors, which include various types, including but not limited to light sensors and angle sensors.

[0056] In some embodiments, the detection information may also be used for program budgeting or calculation, for example, based on the current light intensity, the distance to the channel on the proposed route, and the relevant information of the aforementioned channel, to calculate the light intensity at a preset time or preset location, as candidate reference information for switching vehicle lights.

[0057] Step S102: Switch the vehicle's lights based on the detection information.

[0058] In some embodiments, the detection information is one or more types.

[0059] In some embodiments, the detection information includes: light intensity, and switching the vehicle's lights based on the detection information includes:

[0060] Compare the light intensity with the set light intensity;

[0061] When the light intensity is greater than the first set light intensity, the vehicle's lights are switched to low beam.

[0062] When the light intensity is less than the second set light intensity, the vehicle's lights are switched to high beams;

[0063] The first set light intensity is greater than or equal to the second set light intensity.

[0064] In some embodiments, the inspection information includes: ramp angle information, and switching the vehicle's lights based on the detection information includes:

[0065] Based on the slope angle information, determine whether the vehicle is going uphill;

[0066] When the vehicle is going uphill, switch the vehicle's lights to high beam.

[0067] When the vehicle is going downhill, switch the vehicle's lights to low beam.

[0068] In some embodiments, determining whether the vehicle is going uphill based on the slope angle information includes:

[0069] Compare the ramp angle with the set ramp angle;

[0070] When the ramp angle is continuously greater than or equal to the set ramp angle for a period of time, the vehicle is determined to be going uphill.

[0071] The set ramp angle is greater than or equal to 0° and less than 90°.

[0072] In some embodiments, the detection information includes the aforementioned light intensity information and slope angle information, and in addition to the cases described above where the vehicle's lights are switched based on the detection information, it also includes:

[0073] When the vehicle is going uphill and the light intensity is greater than the first set light intensity, the vehicle's headlights are switched to low beam.

[0074] As previously stated, the light switching method provided in this application can be implemented by various types of electronic devices, such as terminals. The following description uses a server as an example of an electronic device. Figure 2 The electronic device structure shown in this embodiment includes a processor 210, a memory 220, an external communication interface 230, and a user interface 240. The various components in the electronic device are coupled together via a bus system 250. It is understood that the bus system 250 is used to implement communication between these components. In addition to a data bus, the bus system 250 also includes a power bus, a control bus, and a status signal bus. However, for clarity, in… Figure 2 The general labeled all buses as Bus System 250.

The user interface 240 also includes input means, including user interface components that facilitate user input, such as microphones, touch screen displays, cameras, other input buttons and controls.

[0077] In some embodiments, a user can switch between automatic and manual modes of the vehicle's lights via an input device.

[0078] In some embodiments, users can learn about relevant information regarding vehicle headlight switching through the output device, including but not limited to the conditions for headlight switching and the execution result of headlight switching.

[0079] The memory 220 can be removable, non-removable, or a combination thereof. Exemplary hardware devices include solid-state storage, hard disk drives, optical disk drives, etc. Memory includes, for example, one or more storage devices physically located away from the processor.

[0080] The memory 220 may include volatile memory or non-volatile memory, or both. The non-volatile memory may be read-only memory (ROM), and the volatile memory may be random access memory (RAM). The memory 220 described in this application embodiment is intended to include any suitable type of memory.

[0081] In some embodiments, memory 220 is capable of storing data to support various operations, examples of which include programs, modules, and data structures or subsets or supersets thereof, as illustrated below.

[0082] In some embodiments, the lighting switching device provided in this application can be implemented in software. Figure 2A headlight switching device stored in memory 220 is shown. This device can be software in the form of programs and plug-ins, including the following software modules: an acquisition module 2211 for acquiring detection information when the vehicle's lights are in automatic mode; and a headlight switching module 2212 for switching the vehicle's lights based on the detection information. These modules are logically connected and can therefore be arbitrarily combined or further separated according to the functions they implement.

[0083] In some embodiments, the acquisition module 2211 includes an A / D conversion module, which converts the detection information of analog quantities into detection information of digital quantities.

[0084] In some embodiments, the lighting switching module 2212 includes a chip, which includes a microcontroller.

[0085] This application also provides a lighting switching system, including the electronic device and sensor as described above, wherein the sensor is connected to the electronic device and is used to measure detection information and transmit the detection information to the electronic device.

[0086] In some embodiments, the sensor includes: a slope detection sensor and / or a light intensity sensor.

[0087] This application also provides a storage medium storing a computer program that can be executed by one or more processors and can be used to implement the light switching method described in any of the above claims.

[0088] Example 1

[0089] This application provides a lighting switching system for use in a vehicle, including a light intensity sensor and an electronic device. The light intensity sensor is connected to the electronic device, which includes a microcontroller and an A / D conversion module. The A / D conversion module is integrated into the microcontroller. The light intensity sensor measures light intensity information and transmits the light intensity information to the A / D conversion module. The A / D conversion module converts the analog information into digital information and transmits it to the microcontroller. The microcontroller controls the lights according to the light intensity information.

[0090] The light intensity sensor is digital, comprising a thermistor and a photoresistor. It communicates via an I2C bus, converting light intensity values ​​into voltage values. These voltage values ​​are then conditioned and converted back to voltage, supporting four external voltage inputs. The photoresistor outputs a voltage signal between 0 and 5V. When the output voltage of the light intensity sensor reaches a certain value, an alarm is triggered. The higher the voltage, the more prominent the alarm, such as an illuminated indicator light, thus protecting the circuit.

[0091] The working process of the lighting switching system in this embodiment is as follows:

[0092] When the light intensity is lower than the ambient light intensity threshold, the vehicle lights will automatically turn on. The aforementioned activation is automatic by the system, and the ambient light intensity threshold is preset by the driver or the system.

[0093] After activating the automatic mode, the driver can manually switch from automatic to manual mode. When switching from automatic to manual mode, the automatic mode will be automatically reset.

[0094] After activating the vehicle's automatic headlight mode, the system determines the light intensity. If the light intensity is greater than a first preset light intensity, the system switches the vehicle's headlights to low beam. If the light intensity is less than a second preset light intensity, the system switches the vehicle's headlights to high beam. The first preset light intensity is greater than or equal to the second preset light intensity.

[0095] Example 2

[0096] This application provides a lighting switching system for vehicles, including a slope detection sensor and an electronic device. The slope detection sensor is connected to the electronic device, which includes a microcontroller and an A / D conversion module. The A / D conversion module is integrated into the microcontroller. The slope detection sensor measures the slope angle information and transmits the light intensity information to the A / D conversion module. The A / D conversion module converts the analog information into digital information and transmits it to the microcontroller. The microcontroller controls the lights based on the light intensity information and the slope angle information.

[0097] The slope detection sensor is a single-axis tilt sensor, which converts the slope angle into a voltage value. The system uses an 8-bit ADCPCF8591 to check the output value of the single-axis tilt sensor and convert it into the corresponding slope angle value. When a vehicle is detected traveling at a continuous tilt angle of 5° or greater, it is determined that the vehicle is going uphill. The aforementioned angle value can be set to meet the condition of being greater than or equal to 0° and less than 90°. Since the output of the single-axis tilt sensor has a sine function relationship with the direction of gravity, the horizontal direction and the vehicle's travel direction are combined to determine that one direction in the horizontal direction is the x-axis, which forms one side of the slope angle. The slope angle is the angle between the horizontal direction and the slope. When the vehicle is continuously going downhill, the single-axis tilt sensor tilts in the opposite direction and is in an invalid state, so no signal is sent to the microcontroller, and the vehicle is determined to be going downhill.

[0098] The working process of the lighting switching system in this embodiment is as follows:

[0099] When the light intensity is low and the driver's visibility is unclear, the driver can manually turn on the vehicle's lights in automatic mode. After turning on automatic mode, the driver can manually switch to manual mode. When switching from automatic to manual mode, the automatic mode will be automatically reset.

[0100] After activating the automatic mode of the vehicle lights, the system first determines whether the vehicle is going uphill. When the system detects that the vehicle is traveling at a tilt angle of 5° or greater, it determines that the vehicle is going uphill and switches the vehicle lights to high beam. When the single-axis tilt sensor does not send a signal to the microcontroller, it determines that the vehicle is going downhill and switches the vehicle lights to low beam.

[0101] Example 3

[0102] This application provides a headlight switching system. Compared with Embodiment 3, the difference lies in that the slope detection sensor is not a single-axis tilt sensor. In this embodiment, the slope detection sensor detects the angle between the road where the vehicle is located and the horizontal direction. The angle is formed by rotating the side formed by the orthographic projection of the road in the horizontal direction towards the vehicle's travel direction. When the angle is continuously greater than 0° and less than 90°, the vehicle is determined to be going uphill, and the vehicle headlights are switched to high beam; when the angle is greater than 90°, the vehicle is determined to be going downhill, and the vehicle headlights are switched to low beam.

[0103] Example 4

[0104] This application provides a lighting switching system for vehicles, including a light intensity sensor, a slope detection sensor, and electronic equipment. The light intensity sensor and the slope detection sensor are respectively connected to the electronic equipment. The electronic equipment includes a microcontroller and an A / D conversion module, with the A / D conversion module integrated into the microcontroller. The light intensity sensor measures light intensity information and transmits it to the A / D conversion module. The slope detection sensor measures slope angle information and transmits it to the A / D conversion module. The A / D conversion module converts the analog information into digital information and transmits it to the microcontroller. The microcontroller controls the lights based on the light intensity information and the slope angle information.

[0105] The light intensity sensor is the same as in Embodiment 1, and will not be described again here.

[0106] The ramp detection sensor is a single-axis tilt sensor, the same as in Embodiment 2, and will not be described again here.

[0107] The working process of the lighting switching system in this embodiment is as follows:

[0108] When the light intensity is lower than the ambient light intensity threshold, the vehicle lights will automatically turn on. The ambient light intensity threshold is preset by the driver or the system.

[0109] The automatic mode can also be activated manually by the driver. After activating the automatic mode, the driver can manually switch from automatic mode to manual mode. When switching from automatic mode to manual mode, the automatic mode will be automatically reset.

[0110] After activating the vehicle's automatic headlight mode, first determine if the vehicle is going uphill. If so, switch the headlights to high beam. Next, determine the light intensity. If the light intensity is greater than a first preset light intensity, switch the headlights to low beam. If the light intensity is less than a second preset light intensity, switch the headlights to high beam. The first preset light intensity is greater than or equal to the second preset light intensity.

[0111] Example 5

[0112] This application provides a lighting switching system for use in a vehicle, including a light intensity sensor, an infrared heat detector, a slope detection sensor, and electronic equipment. The far-infrared detector, light intensity sensor, and slope detection sensor are respectively connected to the electronic equipment. The difference between this embodiment and embodiment four is that it also includes a far-infrared detector. The infrared heat detector is used to detect living objects, such as pedestrians, in front of the vehicle.

[0113] Compared with Embodiment 4, the working process of this embodiment also includes switching the vehicle lights to low beam when the infrared detector detects a living object and the electronic device determines that the relevant set conditions are met.

[0114] In some embodiments, instruments for detecting other information are also included to detect relevant information as conditional information for vehicle headlight switching.
