Description

Technical Field

[0001] The present application relates to the field of intelligent network connection technology, and in particular to a control method and device for a car ceiling light. Background Art

[0002] At present, with the continuous development of automobile intelligence, networking and sharing technology, the number of electrical appliances in the whole vehicle is increasing, and the demand for electricity in the whole vehicle is also increasing. Therefore, the requirements for the power of the generator selection and the capacity of the battery selection are also increasing, which in turn increases the cost of the whole vehicle. The increase in the cost of the whole vehicle will lead to a decrease in the competitiveness of the vehicle. Therefore, without reducing customer satisfaction with the vehicle, the whole vehicle energy-saving technology or control method that reduces electricity consumption has become the development trend of the whole vehicle power management technology.

[0003] In the related art, the ceiling light inside the car will be turned on for lighting after the vehicle is turned off or when the driver or passenger opens any door, thereby providing lighting convenience for the driver and passenger at night or in dim environments.

[0004] However, in the related art, regardless of whether the external environment of the vehicle is day or night, the car roof light will turn on when the driver or passenger opens the door or turns off the engine. Therefore, if the roof light is turned on during the day or in a relatively bright environment, it will cause a waste of battery power, which will not only increase the power consumption of the entire vehicle, but also increase the generator power and battery capacity of the vehicle. The degree of intelligence is low and the user experience is poor, which needs to be improved urgently. Summary of the invention

[0037] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] The following describes the control method and device of the car ceiling light of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the prior art mentioned in the background technology center above cannot intelligently control the opening and closing of the ceiling light in the car according to the actual situation, and the power demand of the whole vehicle and the cost of the whole vehicle are increasing, and the competitiveness of the car is declining, the embodiment of the present application provides a control method of the car ceiling light, in which the actual brightness of the current external environment of the vehicle can be identified; the actual state of the vehicle and the actual state of each door can be detected; when the actual brightness is less than a preset threshold and the actual state of any door is open, or when the brightness is less than a preset threshold and the actual state of the vehicle is off, the car ceiling light of the vehicle is turned on. Thus, the problem that the prior art cannot intelligently control the opening and closing of the ceiling light in the car according to the actual situation, and the power demand of the whole vehicle is increasing, and the competitiveness of the car is declining is solved.

[0039] Specifically, Figure 1A schematic flow chart of a method for controlling a car ceiling light provided in an embodiment of the present application.

[0040] like Figure 1 As shown, the control method of the automobile ceiling light includes the following steps:

[0041] In step S101 , the actual brightness of the current external environment of the vehicle is identified.

[0042] It is understandable that the actual brightness of the current external environment refers to the luminous flux per unit solid angle and unit projection area when leaving, arriving at or passing through a certain surface. The embodiment of the present application can automatically determine and identify the brightness of the current external environment of the vehicle according to conditions such as the brightness threshold of the vehicle light sensor.

[0043] In the actual implementation process, there are many ways to identify the brightness of the external environment. For example, the embodiment of the present application can detect the brightness of the light in the external environment through the light sensor LS, and provide the light brightness signal of the external environment to the body control module BCM (Body Control Module) through LIN (Local Interconnect Network, low-speed serial communication bus) to identify the actual brightness value of the current environment. As for the light brightness value, in the embodiment of the present application, the outdoor light brightness value on a sunny day can be set between 30000-300000 lux; the outdoor light brightness value on a cloudy day can be set between 3000-10000 lux; the indoor brightness value at dusk can be set between 5-500 lux; and the brightness value at night can be set between 0.03-0.2 lux.

[0044] Therefore, the embodiment of the present application detects and identifies the actual brightness value of the external environment in which the vehicle is currently located, thereby providing data support for the subsequent turning on of the car's ceiling lights.

[0045] In step S102, the actual state of the vehicle and the actual state of each door are detected.

[0046] In the embodiments of the present application, the actual state of the vehicle may refer to the vehicle being in the engine ignition CRANK, engine running RUN, vehicle power on ACC and vehicle off OFF states; and the actual state of the door may refer to the door being open or closed. After identifying the actual brightness of the vehicle's current external environment, the embodiments of the present application further need to detect whether the vehicle is in an off state, and at the same time detect whether the actual state of each door of the vehicle is open. When the vehicle is in an off state or any door is in an open state, the embodiments of the present application also need to detect the activation mode of the vehicle's external lights before or when the vehicle is turned off, such as high beam, low beam, position light or overtaking light mode.

[0047] Specifically, there can be many ways of detection. For example, the embodiment of the present application can control the vehicle start switch through the intelligent entry and start system PEPS (Passive Entry Passive Start), and provide the vehicle start switch power mode status through the CAN (Controller Area Network) bus to detect whether the vehicle is in an off state.

[0048] like Figure 2 As shown, the embodiment of the present application further includes door status switches, such as a left front door status switch, a right front door status switch, a left rear door status switch, and a right rear door status switch. The door status switch is used to receive user instructions and provide hard-wired four-door opening and closing signals according to the user instructions, and the embodiment of the present application determines whether the vehicle door is in an open state based on this signal. In addition, the embodiment of the present application further includes an external light combination switch, and the external light combination switch can be used to receive user instructions and provide hard-wired external light opening and closing signals according to the user instructions, such as turning on or off light signals such as overtaking lights, high beam lights, position lights, automatic lights, and low beam lights.

[0049] Therefore, the embodiment of the present application ensures the subsequent operation of turning on the car's ceiling lights by detecting whether the vehicle is in an ignition-off state, the actual state of each door of the vehicle, and the on state of the vehicle's exterior lights before or when the ignition is turned off.

[0050] In step S103, when the actual brightness is less than a preset threshold and the actual state of any door is open, or when the brightness is less than a preset threshold and the actual state of the vehicle is off, the vehicle's roof light is turned on.

[0051] It can be understood that the preset threshold here refers to the set light brightness critical value, which is used to judge the brightness of the external environment.

[0052] In the actual implementation process, the embodiment of the present application can, but is not limited to, set the preset threshold value of the brightness of the external environment light to 10000 lux. When the brightness value of the environment light is greater than 10000 lux, it means that the external environment is bright, and the car dome light does not need to be turned on at this time; and when the brightness value of the environment light is less than 10000 lux, it means that the external environment is dark, and the car dome light needs to be turned on at this time. When the vehicle's dome light switch is in the DOOR gear, and the vehicle is in the off state or any door of the vehicle is open, the embodiment of the present application first detects the state of the vehicle's external light before or at present, and if any of the high beam, low beam and position light is in the lit state, the operation of turning on the car dome light is executed; if the high beam, low beam and position light are all in the off state, the embodiment of the present application performs the next detection condition, that is, detecting the brightness of the light of the external environment, and if the brightness of the external environment light is lower than the calibrated critical value, the operation of turning on the car dome light is executed.

[0053] It should be noted that the preset threshold can be set by those skilled in the art according to actual conditions, and is only provided for illustrative purposes without any specific limitation.

[0054] In the above statement logic, the car dome light is automatically turned on or off according to the external light status and the brightness of the external environment. If the user wants to change the state of the car dome light at this time, he can control the change of the car dome light state by switching the dome light switch gear state according to his own needs. When the dome light switch is in the ON gear, the car dome light is on; when the dome light switch is in the OFF gear, the car dome light remains off.

[0055] It should be noted that in the car ceiling light control logic, the ceiling light switch status condition has a higher priority than the external light status signal and the external ambient light brightness signal to meet the user's special needs without affecting the user's convenience in using the light.

[0056] Therefore, the embodiment of the present application determines whether to turn on the car dome light by comparing the actual brightness of the vehicle's current external environment with a preset threshold, thereby improving the accuracy of turning on the car dome light and improving the user experience.

[0057] Optionally, in one embodiment of the present application, when the actual brightness is greater than or equal to a preset threshold and the actual state of any door is open, or when the actual brightness is greater than or equal to a preset threshold and the actual state of the vehicle is off, the car ceiling light is kept off.

[0058] Furthermore, when it is determined that the external environment is brighter, that is, the brightness of the external environment light is higher than the calibrated critical value of 10,000 lux, the embodiment of the present application will not turn on the ceiling light after the vehicle is turned off or when the driver or passenger opens any door.

[0059] Therefore, the embodiment of the present application does not turn on the ceiling light when the brightness of the external ambient light is higher than the critical value, which not only reduces the power consumption of the entire vehicle and improves the economy of the entire vehicle, but also reduces the generator selection power and battery selection capacity of the entire vehicle.

[0060] Optionally, in one embodiment of the present application, before turning on the vehicle's ceiling light, it also includes: determining whether the vehicle meets a preset ceiling light control condition; if the vehicle meets the preset ceiling light control condition, controlling the vehicle to enter a ceiling light energy-saving mode.

[0061] As an embodiment, the preset ceiling light control condition can be understood here as the condition for controlling the vehicle's electrical energy, such as the current battery capacity of the vehicle is below 50% or the driver and passengers manually select the economic driving mode, so that the vehicle can be in an energy-saving state at this time.

[0062] For example, the present application can set the brightness of the ceiling light to three states: strong light, dim light, and weak light. The ceiling light energy-saving mode is when the ceiling light is in dim light and weak light state. Furthermore, before turning on the car ceiling light, the embodiment of the present application also needs to determine whether the vehicle meets the preset ceiling light control conditions at this time. If the vehicle meets the preset ceiling light control conditions, the embodiment of the present application controls the vehicle to enter the ceiling light energy-saving mode, and the car ceiling light is turned on with a dim light; if the preset ceiling light control conditions are not met, the car ceiling light can be turned on in strong light mode. It should be noted that the preset ceiling light control conditions can be set by those skilled in the art according to actual conditions and are not specifically limited here.

[0063] Therefore, the embodiment of the present application controls the vehicle to enter the ceiling light energy-saving mode by determining whether the vehicle meets the preset ceiling light control conditions, thereby reducing the power consumption of the entire vehicle and improving the user's driving experience.

[0064] Optionally, in one embodiment of the present application, the preset ceiling light control condition includes that the current SOC of the vehicle is less than a preset SOC value or the vehicle is in an energy-saving condition.

[0065] It should be understood by those skilled in the art that SOC reflects the remaining capacity of the battery, that is, the ability of the battery to continue to work. When the discharge is complete, the SOC is 0, and when it is fully charged, the SOC is 1, that is, it is generally expressed as 0-100%. The battery SOC can be estimated by parameters such as the battery terminal voltage, charging current and internal resistance, and displayed on the vehicle display to prompt the driver of the vehicle's remaining power and mileage.

[0066] In the actual implementation process, the embodiments of the present application may, but are not limited to, set the preset SOC to 50%. When the actual SOC of the vehicle is lower than 50%, it is determined that the vehicle is in low power mode, and the system controls the car ceiling lights to enter energy-saving mode. When the vehicle is in energy-saving conditions, the embodiments of the present application will also control the car ceiling lights to enter energy-saving mode to reduce power consumption.

[0067] Therefore, the embodiment of the present application sets the ceiling light control conditions to control the automobile ceiling light to enter the energy-saving mode, thereby reducing the vehicle's power consumption and improving the economy of the entire vehicle.

[0068] Optionally, in one embodiment of the present application, turning on a car dome light of a vehicle includes: determining a target brightness of the car dome light according to actual brightness; and lighting the car dome light according to the target brightness.

[0069] It is understandable that the target brightness of the car dome light refers to the brightness mode determined by the car dome light according to the actual ambient brightness value. The embodiment of the present application can match the specific car dome light brightness according to the actual brightness value range of the external environment, and light up the car dome light after determining the target brightness of the car dome light to achieve lighting.

[0070] For example, the embodiment of the present application can set the car ceiling light to three lighting modes, namely strong light, dim light and weak light. When the light brightness value of the external environment is 3000-10000 lux, the car ceiling light turns on the weak light mode; when the light brightness value of the external environment is 500-3000 lux, the car ceiling light turns on the dim light mode; and when the external environment is dark and the light brightness value is below 500 lux, the car ceiling light turns on the strong light mode.

[0071] Therefore, the embodiment of the present application determines the target brightness of the car ceiling light by the actual brightness of the external environment, so as to match the optimal ceiling light brightness mode, thereby improving the user's driving experience.

[0072] Optionally, in one embodiment of the present application, before turning on the car ceiling light of the vehicle, it also includes: extracting at least one scene feature of the current external environment; determining the current scene of the vehicle based on the at least one scene feature; matching the target operating mode of the car ceiling light according to the current scene, so as to control the operation of the car ceiling light according to the target operating mode.

[0073] It should be noted that the scene feature here refers to the characteristics of the environment in which the vehicle is located. For example, the scene feature that an outdoor environment on a sunny day should have is a high light brightness value; the scene feature that an underground parking lot should have is a low light brightness value and obstacles around. Before turning on the car dome light, the embodiment of the present application also needs to first identify and determine the scene in which the vehicle is currently located; then match the corresponding target operation mode of the car dome light according to the current scene in which the vehicle is located; and finally control the operation of the car dome light according to the target operation mode of the car dome light.

[0074] As a feasible method, the embodiment of the present application can firstly take a picture of the scene in which the vehicle is currently located through the vehicle-mounted camera, and extract the scene features in the picture; after collecting the scene features, the embodiment of the present application can further model and analyze the collected data, input the collected scene features into the preset scene classification model for training, and obtain the specific scene in which the vehicle is currently located; finally, different car top light operation modes are matched according to different scenes. For example, when the current scene is identified as an underground parking lot, the environment is relatively dark, and the car top light is turned on in strong light mode; when the current scene is identified as outdoors on a sunny day, the light brightness is relatively high, and the car top light is turned off; when the scene is identified as outdoors on a cloudy day, the car top light is turned on in low light mode.

[0075] Therefore, the embodiment of the present application identifies the scene in which the current vehicle is located to match the corresponding car ceiling light operation mode, thereby improving the accuracy of setting the light intensity of the car ceiling light, realizing intelligent control of the car ceiling light, and reducing the vehicle's power consumption.

[0076] The following is a specific embodiment and a schematic diagram of the execution logic of the vehicle ceiling light control method of the present application is described in conjunction with the accompanying drawings.

[0077] Figure 3 The following is a schematic diagram of the execution logic of the car ceiling light control method. Figure 3 As shown, the car ceiling light control logic of this application is as follows:

[0078] S301: Detect the gear state of the car dome light. If the car dome light switch is in the DOOR gear, execute S302; if the car dome light switch is in the ON gear, execute S307; if the car dome light switch is in the OFF gear, execute S309;

[0079] S302: The car ceiling light switch is in the DOOR position, and S303 is executed;

[0080] S303: The vehicle is turned off or any door is opened, and S304 is executed;

[0081] S304: Determine the state of the exterior lights of the vehicle before or at present, if the high beam, low beam and position lights are all off, execute S305; if any one of the high beam, low beam and position lights is on, execute S308;

[0082] S305: Determine the relationship between the brightness of the external light and the critical value. If the brightness is higher than the critical value, execute S306; if the brightness is lower than the critical value, execute S308;

[0083] S306: Turn off the car ceiling light and continue to execute S301;

[0084] S307: The car ceiling light switch is turned on, and S308 is executed;

[0085] S308: Turn on the car ceiling light and continue to execute S301;

[0086] S309: The car ceiling light switch is in the OFF position, and S306 is executed;

[0087] According to the embodiment of the present application, the actual brightness of the current external environment of the vehicle is identified, and the actual state of the vehicle and the actual state of each door are detected to intelligently control the opening and closing of the car ceiling light. When the actual brightness is less than a certain value and the actual state of any door is open, or when the brightness is less than a certain value and the actual state of the vehicle is off, the embodiment of the present application turns on the car ceiling light of the vehicle, thereby realizing intelligent control of the car ceiling light, reducing the power consumption of the whole vehicle, and improving the economy of the whole vehicle and the driving experience of the user. Thus, the problems that the prior art cannot intelligently control the opening and closing of the interior ceiling light according to the actual situation, and the power demand of the whole vehicle is increasing, and the competitiveness of the vehicle is declining are solved.
