Description

Technical Field

[0001] This application relates to the field of automotive intelligent electronic technology, and in particular to a method and device for intelligent prompting of physical buttons in vehicles. Background Technology

[0002] With the continuous development of society, automobiles have become an indispensable means of transportation in people's daily lives, and the resulting traffic safety issues have increasingly attracted people's attention. Therefore, automobile safety has become a major direction for the future development of automobiles.

[0003] Currently, in-vehicle buttons are basically divided into two types: virtual buttons set in the central control screen and physical buttons. Although physical buttons have simpler and more fixed functions compared to virtual buttons, they are more suitable for drivers to operate blindly while driving.

[0004] However, when there are many physical buttons, they are concentrated in one place, and the shape and triggering method of the physical buttons are similar, the driver may not be able to distinguish these physical buttons well by blind operation, which may lead to accidental touches, thereby distracting the driver and causing safety hazards. Summary of the Invention

[0005] In view of this, this application provides a method and device for intelligent prompting of physical buttons in vehicles, enabling drivers to quickly distinguish physical buttons even through blind operation, thereby improving driving safety.

[0006] Specifically, the following technical solutions are included:

[0007] On the one hand, this application provides a method for intelligent prompting of in-vehicle physical buttons, the method including:

[0008] Infrared sensors installed inside the physical buttons detect whether a finger is approaching the button.

[0009] When a finger approaches a physical button, the blower inside the button is activated, allowing air to be blown out through the nozzle on the button.

[0010] When the conditions for stopping the blowing are met, the blowing device located inside the physical button will be turned off.

[0011] Alternatively, the method may also include:

[0012] When an infrared sensor located inside the physical button detects a finger approaching the button, the button's key identifier is obtained.

[0013] Turn on the blower device located inside the physical button, and control the opening and closing state of the heating wire of the blower device according to the button markings, so that natural wind or hot air is blown out through the air outlet located on the physical button.

[0014] Optionally, when the conditions for stopping the blowing are met, the blowing device located inside the physical button is turned off, including:

[0015] When the blower operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the conditions for stopping the blower are met, and the blower inside the physical button is turned off.

[0016] Alternatively, the method may also include:

[0017] When a finger approaches the physical button, the air generated by the car's air conditioning is directed to the physical button through the air duct, and the air is blown out through the air outlet set on the physical button.

[0018] Alternatively, the method may also include:

[0019] When an infrared sensor located inside the physical button detects a finger approaching the button, the button's key identifier is obtained.

[0020] According to the button labels, control the on / off state of the compressor or heat pump of the vehicle air conditioner, and direct one of the air types generated by the vehicle air conditioner—natural wind, hot air, or cold air—to the physical button through the air duct, so that the air is blown out through the air outlet set on the physical button.

[0021] Alternatively, the method may also include:

[0022] When the airflow from the vehicle's air conditioning system—either natural air, hot air, or cold air—is directed through the air duct to the physical button for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the airflow from the vehicle's air conditioning system—either natural air, hot air, or cold air—is stopped being directed through the air duct to the physical button.

[0023] Alternatively, the air vent may be the mounting gap of the physical button, or the air vent may be located on the edge of the physical button, or the air vent may be located on the top surface of the physical button.

[0024] Alternatively, when the air vent is located on the top surface of the physical button, the method further includes:

[0025] When a finger approaches a physical button, the ventilation device inside the button is activated, drawing air through the vent on the button.

[0026] When the ventilation device operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the ventilation device inside the physical button is turned off.

[0027] Alternatively, physical buttons may include a front windshield defroster button, a rear windshield defroster button, a trunk opening button, an air conditioning compressor start button, or an air conditioning heat pump start button.

[0028] On the other hand, this application also provides an in-vehicle physical button intelligent prompting device, the device comprising:

[0029] The monitoring module is configured to detect whether a finger is near the physical button using an infrared sensor located inside the physical button.

[0030] The ventilation module is configured to activate a blower located inside the physical button when a finger approaches the physical button, allowing air to be blown out through the air vent on the physical button.

[0031] The air-closing module is configured to shut off the air-blowing device located inside the physical button when the conditions for stopping airflow are met.

[0032] The vehicle-mounted physical button intelligent prompting method and device provided in this application, when an infrared sensor installed inside the physical button detects a finger approaching the physical button, it indicates that the driver is looking for the physical button. At this time, a blowing device installed inside the physical button is activated, allowing air to blow out through the air vent on the physical button, thereby using the air to mark the physical button. When the conditions for stopping the blowing are met, the blowing device installed inside the physical button is deactivated, enabling the driver to accurately distinguish the function of the physical button and determine its specific location, thus enabling completely blind operation, avoiding distraction, and improving driving safety.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The embodiments of this application provide the following technical solutions:

[0041] This application provides a method for intelligent prompting of physical buttons in vehicles, enabling drivers to quickly distinguish physical buttons even through blind operation, thus improving driving safety. The method is executed by the vehicle controller. Taking the vehicle controller as an example, as follows... Figure 1 As shown, steps S101, S102, and S103 are included, wherein:

[0042] In step S101, an infrared sensor located inside the physical button is used to detect whether a finger is approaching the physical button.

[0043] In step S102, when a finger approaches the physical button, the blower device inside the physical button is activated, allowing air to be blown out through the blower nozzle on the physical button.

[0044] In step S103, when the conditions for stopping the blowing are met, the blowing device located inside the physical button is turned off.

[0045] In some optional embodiments, the method further includes:

[0046] When an infrared sensor located inside the physical button detects a finger approaching the button, the button's key identifier is obtained.

[0047] Turn on the blower device located inside the physical button, and control the opening and closing state of the heating wire of the blower device according to the button markings, so that natural wind or hot air is blown out through the air outlet located on the physical button.

[0048] In some optional embodiments, when the conditions for stopping the blowing are met, the blowing device located inside the physical button is turned off, including:

[0049] When the blower operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the conditions for stopping the blower are met, and the blower inside the physical button is turned off.

[0050] In some optional embodiments, the method further includes:

[0051] When a finger approaches the physical button, the air generated by the car's air conditioning is directed to the physical button through the air duct, and the air is blown out through the air outlet set on the physical button.

[0052] In some optional embodiments, the method further includes:

[0053] When an infrared sensor located inside the physical button detects a finger approaching the button, the button's key identifier is obtained.

[0054] According to the button labels, control the on / off state of the compressor or heat pump of the vehicle air conditioner, and direct one of the air types generated by the vehicle air conditioner—natural wind, hot air, or cold air—to the physical button through the air duct, so that the air is blown out through the air outlet set on the physical button.

[0055] In some optional embodiments, the method further includes:

[0056] When the airflow from the vehicle's air conditioning system—either natural air, hot air, or cold air—is directed through the air duct to the physical button for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the airflow from the vehicle's air conditioning system—either natural air, hot air, or cold air—is stopped being directed through the air duct to the physical button.

[0057] In some alternative embodiments, the air vent is the mounting gap of the physical button, or the air vent is located on the edge of the physical button, or the air vent is located on the top surface of the physical button.

[0058] In some optional embodiments, when the air outlet is positioned on the top surface of the physical button, the method further includes:

[0059] When a finger approaches a physical button, the ventilation device inside the button is activated, drawing air through the vent on the button.

[0060] When the ventilation device operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the ventilation device inside the physical button is turned off.

[0061] In some alternative embodiments, the physical buttons include a front windshield defroster button, a rear windshield defroster button, a trunk opening button, an air conditioning compressor opening button, or an air conditioning heat pump opening button.

[0062] The intelligent prompting method for in-vehicle physical buttons provided in this application indicates that the driver is looking for the physical button when an infrared sensor inside the physical button detects a finger approaching the button. At this time, a blower inside the physical button is activated, allowing air to blow out through the air vent on the physical button, thus using the air to mark the physical button. When the conditions for stopping the blowing are met, the blower inside the physical button is deactivated. This allows the driver to accurately identify the function of the physical button and determine its specific location, enabling completely blind operation, avoiding distraction, and improving driving safety.

[0063] This application also provides a method for intelligent prompting of physical buttons in vehicles, enabling drivers to quickly distinguish physical buttons even through blind operation, thus improving driving safety. The method is executed by the vehicle controller. Taking the vehicle controller as an example, as follows... Figure 2 As shown, the process includes steps S201, S202, S203, and S204, wherein:

[0064] In step S201, an infrared sensor installed inside the physical button is used to detect whether a finger is approaching the physical button.

[0065] In some optional embodiments, since some users may not want to be prompted by blowing air onto buttons, a "Button Air Prompt" option can be set in the central control screen. Users can operate on the central control screen to turn the "Button Air Prompt" option on or off by tapping. When the "Button Air Prompt" option is turned on, the intelligent prompting method for in-vehicle physical buttons provided in this embodiment can be executed.

[0066] Furthermore, when the "Button Airflow Indication" option is enabled, users can customize the settings, assigning a natural airflow indication to one specific in-vehicle physical button and a hot airflow indication to another. This allows drivers to easily distinguish these two physical buttons from other physical buttons, as well as from each other.

[0067] In some optional embodiments, when a driver is driving and there is a significant difference in temperature and humidity between the inside and outside of the vehicle, fogging may occur on the front and rear windshields, side windows, and exterior rearview mirrors. Severe fogging can significantly impair visibility, creating a safety hazard. In such cases, the driver needs to locate and activate the defroster button. However, if the driver is unfamiliar with the locations of the front and rear windshield defroster buttons, they may need to look down to find these physical buttons. In such urgent situations, looking down to find these buttons undoubtedly poses a greater threat to driving safety. To address this scenario, the driver can pre-set the "Button Airflow Indication" option on the central control screen, setting the front windshield defroster button to indicate natural airflow and the rear windshield defroster button to indicate hot airflow. When the driver's finger approaches these buttons, a corresponding airflow indication will be triggered. This allows the driver to easily distinguish these two physical buttons from other physical buttons and also differentiate them from each other, enabling them to locate the required buttons blindly and improving driving safety.

[0068] In some alternative embodiments, a preset condition can be set for the infrared sensor, such as indicating that the driver's finger is close to a physical button when the infrared sensor detects an object with a temperature in the range of 36-38 degrees Celsius entering the detection range.

[0069] In step S202, when a finger approaches the physical button, the button identifier of the physical button is obtained.

[0070] In some optional embodiments, when a finger approaches physical button A, the button identifier "001" of physical button A is obtained; correspondingly, when a finger approaches physical button B, the button identifier "010" of physical button B is obtained. Specifically, physical button A can be a front windshield defroster button, and physical button B can be a rear windshield defroster button.

[0071] In step S203, the blower device installed inside the physical button is turned on, and the opening and closing state of the heating wire of the blower device is controlled according to the button marking, so that natural wind or hot air is blown out through the blower nozzle installed on the physical button.

[0072] Understandably, physical buttons can have their own built-in air blowers, eliminating the need for air conditioning ducts and thus improving control flexibility.

[0073] After activating the air blower mechanism located inside the physical buttons, taking physical button A as the windshield defogger and physical button B as the rear window / rearview mirror heater button as an example, the heating coil of the air blower can be controlled according to the button markings to allow natural or hot air to be blown out through the air vents on the physical buttons. This can be achieved in the following control method:

[0074] According to the button label "001" on physical button A (windshield defogger button), the heating wire of the air blowing device of physical button A is kept in the off state, so that natural air is blown out through the air outlet set on physical button A (windshield defogger button).

[0075] According to the button label "020" on physical button B (rear windshield defroster button), the heating wire of the air blowing device of physical button B is turned on, so that hot air is blown out through the air outlet set on physical button B (rear windshield defroster button).

[0076] In step S204, when the blower operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the conditions for stopping the blower are met, and the blower inside the physical button is turned off.

[0077] Understandably, if the air blower operates for more than a preset time, it indicates that the air blower has been running for too long, and it will be turned off to save vehicle energy. When a physical button is triggered, it means that the driver has found and triggered the required physical button, and the air blower will be turned off to save vehicle energy. When the finger leaves the physical button, it means that the driver may need to control another physical button, and the air blower will be turned off to save vehicle energy.

[0078] In some alternative embodiments, the air vent is the mounting gap of the physical button, or the air vent is located on the edge of the physical button, or the air vent is located on the top surface of the physical button.

[0079] Understandably, since physical buttons have installation margins and there are installation gaps around them, using these gaps directly as air vents can reduce the implementation cost of the solution.

[0080] It's also understandable that the edge of a physical button refers to the side that the driver's hand won't touch when using it. Placing the air vent on the edge of the physical button ensures a good touch experience for the driver.

[0081] It is also understandable that the top surface of a physical button refers to the side with patterns or text markings, which is the side that the driver will touch when touching it. Placing the air vent on the top surface of the physical button ensures the effectiveness of the air blowing indicator.

[0082] In some alternative embodiments, the physical buttons include a front windshield defroster button, a rear windshield defroster button, a trunk opening button, an air conditioning compressor opening button, or an air conditioning heat pump opening button.

[0083] Understandably, some of these physical buttons are those that need to be activated promptly while the vehicle is in motion, such as the front windshield defroster button, the rear windshield defroster button, the air conditioning compressor start button, and the air conditioning heat pump start button. Others are buttons that are easily accidentally pressed while the vehicle is in motion, such as the trunk open button.

[0084] The vehicle-mounted physical button intelligent prompting method provided in this application uses an infrared sensor to detect whether a finger is approaching the physical button. When a finger approaches the physical button, a blower device installed inside the physical button is activated. Depending on which physical button it is, the opening and closing state of the heating wire of the blower device is flexibly controlled, allowing natural wind or hot air to be blown out through the air vent on the physical button. This allows the driver to easily distinguish these physical buttons even when operating them blindly, improving driving safety. Moreover, the blower device is turned off in time after the conditions for stopping the blower are met, reducing the energy consumption of the entire vehicle.

[0085] This application also provides a method for intelligent prompting of physical buttons in vehicles, enabling drivers to quickly distinguish physical buttons even through blind operation, thus improving driving safety. The method is executed by the vehicle controller. Taking the vehicle controller as an example, as follows... Figure 3 As shown, the process includes steps S301, S302, S303, and S304, wherein:

[0086] In step S301, an infrared sensor located inside the physical button is used to detect whether a finger is approaching the physical button.

[0087] In step S302, when an infrared sensor located inside the physical button detects that a finger is approaching the physical button, the button identifier of the physical button is obtained.

[0088] In step S303, according to the button label, the on / off state of the compressor or heat pump of the vehicle air conditioner is controlled, and one of the air types generated by the vehicle air conditioner, namely natural wind, hot air or cold air, is directed to the physical button through the air duct, so that the air is blown out through the air outlet set on the physical button.

[0089] Understandably, instead of providing a separate air blower for the physical buttons, one could utilize the air conditioning function to deliver the natural air, hot air, or cold air from the air conditioner to the specific physical buttons via an air duct.

[0090] Unlike heating wires, air conditioners can blow out cold air in addition to hot air, thus allowing for the differentiation of more physical buttons.

[0091] For example, the button for turning on the air conditioner compressor (C) is labeled "011", the button for turning on the air conditioner heat pump (D) is labeled "100", and the button for turning on the trunk (E) is labeled "101".

[0092] In vehicles equipped with both an air conditioning compressor and a heat pump, the compressor is generally used for cooling and is related to the sensory perception of "cold." Therefore, the compressor activation button C should use cold air as a notification. Conversely, the heat pump is generally used for heating and is related to the sensory perception of "heat." Therefore, the heat pump activation button D should use hot air as a notification. The trunk opening button E is generally prone to accidental activation; natural wind is sufficient.

[0093] Therefore, according to the button markings, controlling the on / off state of the vehicle's air conditioning compressor or heat pump, and directing one type of airflow—natural wind, hot air, or cold air—generated by the vehicle's air conditioning through the air duct to the physical button, so that the air is blown out through the air outlet set on the physical button, can include:

[0094] According to the button label "011" on the air conditioning compressor start button C, the vehicle air conditioning compressor is turned on and the heat pump is turned off. The cold air generated by the vehicle air conditioning is directed to the air conditioning compressor start button C through the air duct, and the cold air is blown out through the air outlet set on the air conditioning compressor start button C.

[0095] According to the button marking "100" on the air conditioning heat pump start button D, the compressor of the vehicle air conditioner is turned off and the heat pump is turned on. The hot air generated by the vehicle air conditioner is directed to the air conditioning heat pump start button D through the air duct, and the hot air is blown out through the air outlet set on the air conditioning heat pump start button D.

[0096] According to the button label "101" on the trunk opening button E, the compressor and heat pump of the vehicle's air conditioning are turned off, and the natural air generated by the vehicle's air conditioning is directed to the trunk opening button E through the air duct, so that the natural air is blown out through the air outlet set on the trunk opening button E.

[0097] In step S304, when the natural wind, hot air, or cold air generated by the vehicle air conditioner is circulated through the air duct to the physical button for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the circulation of the natural wind, hot air, or cold air generated by the vehicle air conditioner to the physical button through the air duct is stopped.

[0098] In some alternative embodiments, the air vent is the mounting gap of the physical button, or the air vent is located on the edge of the physical button, or the air vent is located on the top surface of the physical button.

[0099] In some alternative embodiments, the physical buttons include a front windshield defroster button, a rear windshield defroster button, a trunk opening button, an air conditioning compressor opening button, or an air conditioning heat pump opening button.

[0100] The intelligent prompting method for in-vehicle physical buttons provided in this application uses an infrared sensor to detect whether a finger is approaching the physical button. When a finger approaches the physical button, the system flexibly controls the on / off state of the compressor or heat pump of the vehicle's air conditioning system, directing one of the air types—natural air, hot air, or cold air—through an air duct to the physical button. The air then blows out through an air outlet on the physical button, allowing the driver to easily distinguish these physical buttons even when operating them blindly, thus improving driving safety. Furthermore, once the conditions for stopping the blowing are met, the system promptly stops directing one of the air types—natural air, hot air, or cold air—through the air duct to the physical button, reducing overall vehicle energy consumption.

[0101] This application also provides a method for intelligent prompting of physical buttons in vehicles, enabling drivers to quickly distinguish physical buttons even through blind operation, thus improving driving safety. The method is executed by the vehicle controller. Taking the vehicle controller as an example, as follows... Figure 4 As shown, steps S401, S402, and S403 are included, wherein:

[0102] In step S401, an infrared sensor located inside the physical button is used to detect whether a finger is approaching the physical button.

[0103] In step S402, when an infrared sensor located inside the physical button detects that a finger is approaching the physical button, the ventilation device located inside the physical button is activated, and ventilation is performed through the air vent located on the top surface of the physical button.

[0104] Understandably, the top surface of a physical button refers to the side with the graphic or text markings, the side the driver touches. Besides using a blowing indicator, a ventilation system can also effectively help drivers distinguish different physical buttons. Activating the ventilation device inside the physical button creates negative pressure at the air vent on its top surface. When the driver places their finger on the top surface of that button, they can feel their finger being gently drawn in by the air vent. This suction effect doesn't occur when placing a finger on other physical buttons, allowing the driver to easily locate the button even without looking and differentiate it from others.

[0105] In some optional embodiments, the air vent on the top surface of the physical button can be configured as a plurality of evenly arranged small holes, each with a diameter of 1 mm, to ensure that the printing of the pattern and text on the top of the physical button is not affected, and the suction force on the finger is not too strong. The physical button that uses the ventilation method for reminder can be a physical button that is easy to be accidentally pressed, such as a trunk opening button.

[0106] In step S403, when the ventilation device operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, the ventilation device inside the physical button is turned off.

[0107] In some alternative embodiments, the physical buttons include a front windshield defroster button, a rear windshield defroster button, a trunk opening button, an air conditioning compressor opening button, or an air conditioning heat pump opening button.

[0108] The vehicle-mounted physical button intelligent prompting method provided in this application uses an infrared sensor to detect whether a finger is approaching the physical button. When a finger approaches the physical button, the ventilation device inside the physical button is activated, and air is drawn through the air vent on the top surface of the physical button. This allows the driver to easily distinguish these physical buttons even when operating them blindly, improving driving safety. Moreover, the ventilation stops in time after the stopping conditions are met, reducing the energy consumption of the entire vehicle.

[0109] This application also provides an intelligent prompting device for in-vehicle physical buttons, which can be installed in the vehicle controller, such as... Figure 5 As shown, the device includes:

[0110] The monitoring module 501 is configured to detect whether a finger is approaching the physical button via an infrared sensor located inside the physical button.

[0111] Ventilation module 502 is configured to activate a blower located inside the physical button when a finger approaches the physical button, so that air is blown out through the air vent located on the physical button.

[0112] The air-closing module 503 is configured to shut off the air-blowing device located inside the physical button when the conditions for stopping airflow are met.

[0113] In some alternative embodiments, the device further includes an acquisition module 504 configured to acquire the key identifier of the physical key when an infrared sensor located inside the physical key detects that a finger is approaching the physical key.

[0114] In some optional embodiments, the ventilation module 502 is also configured to activate the air blowing device located inside the physical button, and control the opening and closing state of the heating wire of the air blowing device according to the button marking, so that natural wind or hot air is blown out through the air blowing port located on the physical button.

[0115] In some optional embodiments, the air-closing module 503 is further configured to shut down the air-blowing device located inside the physical button when the blowing device operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor located inside the physical button detects that a finger has left the physical button.

[0116] In some alternative embodiments, the ventilation module 502 is also configured to direct air generated by the vehicle air conditioner to the physical button through an air duct when a finger approaches the physical button, so that the air is blown out through an air outlet set on the physical button.

[0117] In some optional embodiments, the ventilation module 502 is also configured to: control the on / off state of the compressor or heat pump of the vehicle air conditioner according to the button identifier, and direct one of the air, such as natural wind, hot air or cold air generated by the vehicle air conditioner, to the physical button through the air duct, so that the air is blown out through the air outlet set on the physical button.

[0118] In some optional embodiments, the air-closing module 503 is further configured to: stop supplying one of the natural wind, hot air, or cold air generated by the vehicle air conditioner to the physical button through the air duct for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button, then stop supplying one of the natural wind, hot air, or cold air generated by the vehicle air conditioner to the physical button through the air duct.

[0119] In some alternative embodiments, the air vent is the mounting gap of the physical button, or the air vent is located on the edge of the physical button, or the air vent is located on the top surface of the physical button.

[0120] In some optional embodiments, when the air vent is located on the top surface of the physical button, the ventilation module 502 is also configured to activate the exhaust device located inside the physical button when a finger approaches the physical button, and exhaust air through the air vent located on the physical button.

[0121] The air-closing module is also configured to shut down the air-closing device inside the physical button when the exhaust device operates for more than a first preset time, or when the physical button is triggered, or when the infrared sensor inside the physical button detects that a finger has left the physical button.

[0122] In some alternative embodiments, the physical buttons include a front defroster button, a rear defroster button, a trunk opening button, an air conditioning compressor start button, or an air conditioning heat pump start button.

[0123] The vehicle-mounted physical button intelligent prompting device provided in this application uses an infrared sensor to detect whether a finger is approaching the physical button. When a finger approaches the physical button, the air blowing device inside the physical button is activated. Depending on which physical button it is, the opening and closing state of the heating wire of the air blowing device is flexibly controlled, so that natural wind or hot air is blown out through the air outlet on the physical button. This allows the driver to easily distinguish these physical buttons even if operating them blindly, improving driving safety. Moreover, the air blowing device is turned off in time after the conditions for stopping the air blowing are met, reducing the energy consumption of the entire vehicle.

[0124] This embodiment and the method embodiment are based on the same inventive concept and are device embodiments corresponding to the method embodiments. Therefore, those skilled in the art should understand that the description of the method embodiment is also applicable to this embodiment, and some technical details will not be described in detail in this embodiment.
