Description

Technical Field

[0001] This invention relates to the field of vehicle control, and more particularly to a vehicle intelligent welcome control method and system. Background Technology

[0002] Intelligent car welcome systems provide drivers and passengers with a more convenient and comfortable travel experience. They mainly use intelligent technologies such as sensor technology, intelligent recognition technology, vehicle communication technology, and human-computer interaction to execute corresponding functions. How to provide more reliable and intelligent welcome services has become a major challenge for intelligent car welcome systems.

[0003] Currently, most vehicles use relatively fixed welcome modes, lacking adaptability to different weather conditions and unable to provide appropriate welcome services in complex weather environments. Furthermore, in extreme conditions, a fixed welcome mode can significantly reduce the quality of the welcome service. Additionally, when passengers approach the vehicle, the vehicle typically activates welcome lights, automatically unlocks, and retracts the seats using memory functions. However, most vehicles currently only support preset, fixed, and single welcome modes. This lacks personalized customization options, requiring passengers to manually operate buttons to control lights, air conditioning, and windows, failing to achieve intelligent and automated control of these components. Finally, these welcome mode functions fail to create effective interaction with the owner and passengers, lacking the necessary human-machine interface experience and making it difficult to adapt to the future development trend of intelligent driving. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a vehicle intelligent welcome control method and system that identifies environmental information, executes different welcome strategies for different environments, and provides reliable welcome services.

[0005] To achieve the above objectives, embodiments of the present invention provide a vehicle intelligent welcome control method, comprising:

[0006] Based on the distance between passengers and the vehicle, different welcome control signals are responded to to generate corresponding welcome activation commands;

[0007] Based on the corresponding welcome activation command, obtain different weather environment information and activate the welcome mode under different weather conditions;

[0008] The welcoming actions will be performed according to the welcoming mode under different weather conditions.

[0009] This invention proposes a vehicle intelligent welcome control method that senses the distance between passengers and the vehicle and issues different welcome control signals accordingly. This allows for immediate response to passenger needs. Furthermore, by combining weather information, it automatically generates and executes welcome actions tailored to individual preferences, significantly enhancing the personalization and intelligence of the passenger experience. Correspondingly, it identifies and adapts to different weather conditions, automatically switching to the most suitable welcome mode and generating welcome actions for different weather conditions, providing reliable welcome service actions.

[0010] Furthermore, the step of generating corresponding welcome activation commands based on the positional distance between passengers and the vehicle in response to different welcome control signals includes:

[0011] When the distance between the passenger and the vehicle is less than a first preset distance value, a first welcome control signal is triggered; wherein, the first welcome control signal includes: a local hard-wired welcome control signal, a key welcome control signal, or a remote welcome control signal;

[0012] When the distance between the passenger and the vehicle is greater than a first preset distance value and less than a second preset distance value, a second welcome control signal is triggered; wherein, the second welcome control signal includes: a key welcome control signal or a remote welcome control signal;

[0013] When the distance between the passenger and the vehicle is greater than a second preset distance value, a third welcoming control signal is triggered; wherein, the third welcoming control signal includes: a remote welcoming control signal;

[0014] Based on the first welcoming control signal, the second welcoming control signal, or the third welcoming control signal, a corresponding welcoming start command is generated.

[0015] The present invention proposes a vehicle intelligent welcome control method, which sets multiple welcome signal acquisition methods according to different distances between passengers and the vehicle, making the control of the welcome mode more flexible.

[0016] Furthermore, it also includes:

[0017] When responding to the first welcome control signal, if there is no key welcome control signal or remote welcome control signal, the first welcome opening command is generated by responding to the local hardwire welcome control signal; if there is a key welcome control signal but no remote welcome control signal, the first welcome opening command is generated by responding to the key welcome control signal; if there is a remote welcome control signal, the first welcome opening command is generated by responding to the remote welcome control signal.

[0018] When responding to the second welcoming control signal, if there is no remote welcoming control signal, the second welcoming opening command is generated by responding to the key welcoming control signal; if there is a remote welcoming control signal, the second welcoming opening command is generated by responding to the remote welcoming control signal.

[0019] When responding to the third welcoming control signal, a third welcoming activation command is generated by responding to the remote welcoming control signal.

[0020] The present invention proposes a vehicle intelligent welcome control method, which, under the premise of acquiring multiple welcome signals, also distinguishes the priority of each signal to avoid signal redundancy caused by the simultaneous occurrence of multiple signals, thereby improving the vehicle's recognition accuracy of the welcome start command.

[0021] Furthermore, based on the corresponding welcome activation command, different weather environment information is obtained, and different welcome modes are activated under different weather conditions, including:

[0022] Upon receiving the first, second, or third welcome opening command, different weather environment information is obtained, including rainfall information, sunshine information, and temperature information.

[0023] When rainfall and sunshine information meet the preset requirements, the rainy day welcome mode is activated and a voice reminder is issued.

[0024] When the temperature is below the preset temperature threshold, the ice and snow welcome mode will be activated and a voice reminder will be issued.

[0025] When the temperature exceeds the preset temperature threshold, the "Hot Summer Welcome Mode" is activated and a voice reminder is issued.

[0026] Furthermore, the provision of corresponding welcoming actions based on different weather conditions includes:

[0027] When the rainy weather welcome mode is activated, the vehicle area controller drives the various components of the vehicle to perform the corresponding rainy weather welcome actions.

[0028] When the ice and snow welcome mode is activated, the vehicle area controller drives the various components of the vehicle to perform the corresponding ice and snow welcome actions.

[0029] When the "Hot Summer Welcome Mode" is activated, the vehicle area controller drives various vehicle components to perform corresponding hot summer welcome actions.

[0030] Furthermore, when the rainy weather welcome mode is activated, the vehicle area controller drives various vehicle components to perform corresponding rainy weather welcome actions, including:

[0031] When the rain welcome mode is activated, the vehicle's area controller will drive the front and rear fog lights to turn on.

[0032] The vehicle area controller activates the rearview mirror heating and defrosting function.

[0033] Based on rainfall information, the vehicle area controller drives the windshield wipers to perform wiper actions at different speeds.

[0034] Furthermore, when the ice and snow welcome mode is activated, the vehicle area controller drives various vehicle components to perform corresponding ice and snow welcome actions, including:

[0035] When the Ice and Snow Welcome Mode is activated, the vehicle area controller will activate the rearview mirror heating and defrosting function.

[0036] The vehicle area controller monitors snowfall information and drives the windshield wipers to perform wiper actions at different speeds.

[0037] The vehicle area controller monitors temperature information and drives the air conditioner to be set to the first preset temperature value.

[0038] The vehicle area controller drives the door handle heating to break ice.

[0039] Furthermore, when the "Hot Summer Welcome Mode" is activated, the vehicle area controller drives various vehicle components to perform corresponding hot summer welcome actions, including:

[0040] When the "Welcome to Summer" mode is activated, the vehicle's zone controller will drive the windows to open or close.

[0041] The vehicle's zone controller drives the air conditioning to the second preset temperature value.

[0042] The intelligent vehicle welcome control method proposed in this embodiment of the invention further includes:

[0043] Based on the facial information of passengers, the system compares it with the passenger information stored in a pre-set database to determine the passenger's identity.

[0044] When the passenger's identity information is a fixed passenger, respond to the dedicated passenger's greeting instruction, based on the greeting mode under different weather conditions, and control the vehicle area controller to drive the vehicle's various components to perform the corresponding dedicated greeting actions;

[0045] When the passenger's identity information is that of a non-fixed passenger, the vehicle responds to the basic passenger greeting instruction, and controls the vehicle area controller to drive the various components of the vehicle to perform the corresponding basic greeting actions based on the greeting mode under different weather conditions.

[0046] This invention proposes a vehicle intelligent welcome control method that, based on conventional recognition technologies such as welcome target recognition and weather environment recognition, adds more complex control strategies and judgment logic. It determines different welcome modes based on different weather conditions and automatically sets corresponding functions to execute exclusive welcome actions based on the attributes of passengers. This overcomes the shortcomings of low practicality and redundant user experience, ultimately achieving the recognition of environmental and passenger information, executing different welcome strategies for different environments and different passengers, and providing reliable welcome services.

[0047] This invention also provides a vehicle intelligent welcome control system, including: a welcome activation command acquisition module, a welcome mode recognition module, and a vehicle control module;

[0048] The welcome opening command acquisition module is used to generate corresponding welcome opening commands based on the positional distance between passengers and the vehicle in response to different welcome control signals.

[0049] The welcoming mode recognition module is used to obtain different weather environment information based on the corresponding welcoming activation command, and activate the welcoming mode under different weather conditions.

[0050] The vehicle control module is used to perform corresponding welcoming actions based on the welcoming mode under different weather conditions.

[0051] This invention proposes a vehicle intelligent welcome control system. A welcome activation command acquisition module senses the distance between passengers and the vehicle, and issues different welcome control signals accordingly, enabling immediate response to passenger needs. Simultaneously, a welcome mode recognition module, combined with weather information, automatically generates and executes welcome actions tailored to individual preferences, significantly enhancing the personalization and intelligence of the passenger experience. It also identifies and adapts to different weather conditions, automatically switching to the most suitable welcome mode through the vehicle control module, generating welcome actions for different weather conditions, and providing reliable welcome services. Furthermore, based on passenger attributes, it distinguishes between exclusive and basic welcome services, providing reliable and comfortable passenger service. In addition, a vehicle area controller drives various vehicle components to execute welcome service actions, enabling rapid switching of execution logic for different modes, providing reliable and convenient welcome services.

[0052] Beneficial effects:

[0053] By sensing the distance between passengers and the vehicle and issuing different welcome control signals accordingly, the system can respond to passenger needs in real time. Simultaneously, by combining weather information, it automatically generates and executes welcome actions tailored to individual preferences, significantly enhancing the personalization and intelligence of the passenger experience. It can also recognize and adapt to different weather conditions, automatically switching to the most suitable welcome mode and generating appropriate welcome actions for different weather conditions, providing reliable welcome services. Furthermore, based on passenger attributes, it can differentiate between exclusive and basic welcome services, providing passengers with reliable and comfortable service. In addition, by driving various vehicle components to execute welcome service actions through the vehicle's area controller, it can quickly switch execution logic to meet different needs in different modes, providing reliable and convenient welcome services.

[0056] Figure 3 This is a schematic diagram of the module structure of a vehicle intelligent welcome control system according to a certain embodiment of the present invention. Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1

[0059] See Figure 1 , Figure 1 This is a flowchart illustrating the steps of a vehicle intelligent welcome control method according to a certain embodiment of the present invention. Figure 1 As shown in the figure, this embodiment of the invention proposes a vehicle intelligent welcome control method, including steps 101 to 103, the specific steps of which are as follows:

[0060] Step 101: Based on the distance between the passengers and the vehicle, respond to different welcome control signals and generate corresponding welcome activation commands;

[0061] As an example of this embodiment, when the distance between the passenger and the vehicle is less than a first preset distance value, a first welcome control signal is triggered; wherein the first welcome control signal includes: a local hard-wired welcome control signal, a key welcome control signal, or a remote welcome control signal; when the distance between the passenger and the vehicle is greater than the first preset distance value and less than a second preset distance value, a second welcome control signal is triggered; wherein the second welcome control signal includes: a key welcome control signal or a remote welcome control signal; when the distance between the passenger and the vehicle is greater than the second preset distance value, a third welcome control signal is triggered; wherein the third welcome control signal includes: a remote welcome control signal; and a corresponding welcome activation command is generated based on the first welcome control signal, the second welcome control signal, or the third welcome control signal.

[0062] By acquiring different combinations of local hard-wired welcome control signals, key welcome control signals, or remote welcome control signals based on different distance values, multiple executable schemes are provided for activating the vehicle's welcome mode. This prevents limitations caused by acquiring only a single signal, making the activation of the welcome mode more convenient. Specifically, in one possible implementation, when the distance between the passenger and the vehicle is less than a first preset distance, the passenger can send a local hard-wired welcome control signal by pulling the door handle, a key welcome control signal by transmitting a high-frequency signal via the remote key, or a remote welcome control signal via Ethernet communication based on the SOMEIP service. Responding to any of these three signals will automatically generate a welcome activation command. Similarly, when the distance between the passenger and the vehicle is greater than a first preset distance value but less than a second preset distance value, the passenger cannot activate the welcome mode by pulling the door handle. The system can send a local hard-wired welcome control signal, but it can also send a key welcome control signal via a high-frequency signal emitted by the remote key, or a remote welcome control signal via Ethernet communication based on the SOMEIP service. It automatically generates a welcome opening command by responding to these two signals. Finally, when the distance between the passenger and the vehicle exceeds a second preset distance value, the passenger cannot send a local hard-wired welcome control signal by pulling the door handle, nor can they receive the high-frequency signal emitted by the remote key to send a key welcome control signal. Instead, they can only send a remote welcome control signal via Ethernet communication based on the SOMEIP service, thereby generating a welcome opening command. It is worth noting that the first preset distance value can be set as the maximum distance at which the passenger can pull the door handle, and the second preset distance value can be set as the maximum distance at which the high-frequency signal emitted by the remote key can be received.

[0063] As another example of this embodiment, when responding to the first welcoming control signal, if neither the key welcoming control signal nor the remote welcoming control signal exists, a first welcoming opening command is generated by responding to the local hardwired welcoming control signal; if the key welcoming control signal exists but the remote welcoming control signal does not exist, a first welcoming opening command is generated by responding to the key welcoming control signal; if the remote welcoming control signal exists, a first welcoming opening command is generated by responding to the remote welcoming control signal. When responding to the second welcoming control signal, if no remote welcoming control signal exists, a second welcoming opening command is generated by responding to the key welcoming control signal; if the remote welcoming control signal exists, a second welcoming opening command is generated by responding to the remote welcoming control signal; when responding to the third welcoming control signal, a third welcoming opening command is generated by responding to the remote welcoming control signal.

[0064] Under the premise of acquiring multiple execution control signals, multiple signal response priorities are also set to prevent signal redundancy when multiple signals are acquired simultaneously, as their execution functions are all to activate the welcome mode, thus greatly improving the reliability of signal control. Specifically, one possible implementation is that there is a priority order when responding to the welcome activation command. If a local hardwired welcome control signal, a key welcome control signal, or a remote welcome control signal are all present, the priority of the control signal response is: remote welcome control signal > key welcome control signal > local hardwired welcome control signal. If only a local hardwired welcome control signal and a key welcome control signal are present simultaneously, the priority of the control signal response is: key welcome control signal > local hardwired welcome control signal. The corresponding welcome activation command is generated according to the priority order when responding to the welcome activation command.

[0065] Step 102: Based on the corresponding welcome activation command, obtain different weather environment information and activate the welcome mode under different weather conditions;

[0066] As an example of this embodiment, upon receiving a first welcome activation command, a second welcome activation command, or a third welcome activation command, different weather environment information is obtained. The different weather environment information includes: rainfall information, sunshine information, and temperature information. When the rainfall information and sunshine information meet preset requirements, the rainy day welcome mode is activated and a voice reminder is issued. When the temperature information is less than a preset temperature threshold, the ice and snow welcome mode is activated and a voice reminder is issued. When the temperature information is greater than the preset temperature threshold, the scorching heat welcome mode is activated and a voice reminder is issued.

[0067] This invention proposes a vehicle intelligent welcome control method that combines environmental information to obtain the current weather status and activates different welcome modes for different weather conditions, providing passengers with a diversified service experience. It executes different welcome actions for different weather conditions and improves the reliability of welcome actions in diverse and complex weather situations. Specifically, in one possible implementation, upon receiving a welcome activation command (first, second, or third welcome activation command), the current weather environment information is read, and different welcome service modes are activated based on the weather environment information. Specifically, through… By acquiring rainfall and sunlight information, the system determines whether it is currently in a rainy environment. For example, if the rainfall exceeds the rain warning threshold (different warning thresholds can be set according to different regional characteristics) or the duration of rainfall exceeds the warning time (different time thresholds can be set according to different regional characteristics), and the sunlight intensity is lower than the warning value (different values ​​can be set according to different regional characteristics), it is determined that it is in a rainy environment. The system then activates a rainy welcome mode and issues voice reminders such as "The roads are slippery in the rain, please be careful" and "The rainy intelligent welcome mode has been automatically activated for you." It is worth mentioning that the rainy welcome mode can adjust according to the amount of rainfall. (Configurable according to actual conditions) Information is categorized into "Light Rain Mode," "Moderate Rain Mode," and "Heavy Rain Mode." By acquiring temperature information, it determines whether the current environment is icy / snowy or extremely hot. When the temperature is below a preset threshold (e.g., below 23°C), and combined with historical weather data (e.g., snowfall the previous day), real-time weather data (e.g., current snow cover), or weather forecast data for a future period (e.g., 24 hours), it is determined to be in an icy / snowy environment. In this case, the "Ice and Snow Welcome Mode" is activated, issuing voice reminders such as "Icy / snowy weather, please drive carefully" and "Ice and Snow Intelligent Welcome Mode has been automatically activated for you." It's worth mentioning... Yes, the Ice and Snow Welcome Mode can be divided into "Cold Mode (10℃~23℃)" and "Snowy Mode (10℃ and below)" based on the ambient temperature. When the temperature information is higher than the preset temperature threshold (e.g., above 23℃), and combined with the light information (e.g., high light intensity), it determines that it has entered a hot environment. Then, the Hot Summer Welcome Mode is activated, and voice reminders such as "In hot weather, please keep the car ventilated" and "The Hot Summer Intelligent Welcome Mode has been automatically activated for you" are issued. It is worth mentioning that the Hot Summer Welcome Mode can be divided into "Hot Mode (23℃~30℃)" and "Easily Get Heatstroke Mode (30℃ and above)" based on the temperature information.

[0068] Step 103: Perform the corresponding welcoming actions based on the welcoming mode under different weather conditions.

[0069] As an example of this embodiment, when the rainy welcome mode is activated, the vehicle area controller drives the various components of the vehicle to perform corresponding rainy welcome actions; specifically, when the rainy welcome mode is activated, the vehicle area controller drives the front fog lights and rear fog lights to turn on; the vehicle area controller drives the rearview mirror heating and defrosting function to turn on; and based on the rainfall information, the vehicle area controller drives the wipers to perform wiper actions at different speeds.

[0070] This invention proposes a vehicle intelligent welcome control method. In rainy weather, it intelligently controls modules related to rainy travel while deactivating modules unrelated to rain. Point-to-point activation of corresponding modules ensures the accuracy of welcome service actions. Specific implementation methods include: Hardware connection: The vehicle area controller is connected to the windshield wipers, front fog lights, and rear fog lights via wires or a bus. A heating element is installed inside the rearview mirror and connected to the vehicle area controller via wires or a bus. Software control: The vehicle area controller receives the rainy welcome mode activation command and reads rainfall information. Based on the rainfall information, it distinguishes between "light rain mode," "medium rain mode," and "heavy rain mode," driving the windshield wipers to operate at low, medium, and high speeds respectively. It also sends drive control signals to illuminate the front and rear fog lights and activate the rearview mirror heating function to remove water droplets and fog from the mirror surface.

[0071] As an example of this embodiment, when the ice and snow welcome mode is activated, the vehicle area controller drives the various components of the vehicle to perform corresponding ice and snow welcome actions; specifically, when the ice and snow welcome mode is activated, the vehicle area controller drives the rearview mirror heating and defrosting function to be turned on; the vehicle area controller monitors the snowfall information and drives the wipers to perform wiper actions at different speeds; the vehicle area controller monitors the temperature information and drives the air conditioner to be set to the first preset temperature value; the vehicle area controller drives the door handles to be heated and ice-breaking.

[0072] This invention proposes a vehicle intelligent welcome control method. Compared to rainy weather, the welcome service actions performed in icy and snowy weather include temperature regulation, intelligently adapting to different environmental welcome needs. The module's control activation and deactivation are influenced by environmental information, thus identifying and adapting to different weather conditions, automatically switching to the most suitable welcome mode, generating the execution actions for different weather conditions, and providing reliable welcome service actions. Specific implementation methods include: Hardware connection: The vehicle area controller is connected to the windshield wipers and air conditioning via wires or a bus; heating elements are installed in the rearview mirrors and door handles, and these heating elements are connected to the vehicle area controller via wires or a bus; Software control: The vehicle area controller receives the icy and snowy welcome mode activation command and reads the temperature information, distinguishing between different weather conditions based on the temperature information. The vehicle offers two modes: "Cold Mode (10℃~23℃)" and "Snow Mode (10℃ and below)". When entering Cold Mode (10℃~23℃), the windshield wipers and door handle heaters are not activated. The rearview mirror heaters are activated to remove frost, and the air conditioning is turned on and set to a comfortable temperature based on the ambient temperature. Different temperatures can also be set according to passenger preferences. When entering Snow Mode (10℃ and below), the vehicle's zone controller sends a signal to activate the rearview mirror and door handle heaters to remove snow and frost. It also sends a signal to activate the windshield wipers, adjusting their speed (low, medium, or high) according to the amount of snow. The air conditioning is also activated and adjusted to a comfortable temperature (e.g., 26℃) based on the interior and exterior temperatures.

[0073] As an example of this embodiment, when the "Hot Summer Welcome Mode" is activated, the vehicle area controller drives various vehicle components to perform corresponding hot summer welcome actions. Specifically, when the "Hot Summer Welcome Mode" is activated, the vehicle area controller drives the windows to open or close; the vehicle area controller also drives the air conditioning to be set to a second preset temperature value.

[0074] This invention proposes a vehicle intelligent welcome control method. The "Hot Summer Mode" and "Snowy Mode" cover a wide temperature range, essentially encompassing all possible environmental conditions during daily travel, providing comprehensive welcome services. Specific implementation methods include: Hardware connection: The vehicle area controller is connected to the windows and air conditioning via wires or a bus; Software control: The vehicle area controller receives the "Hot Summer Welcome Mode" activation command and reads temperature information. Based on the temperature information, it distinguishes between "Hot Mode (23℃~30℃)" and "Heatstroke Mode (30℃ and above)". When "Hot Mode (23℃~30℃)" is selected, the vehicle area controller sends a control signal to open the windows for ventilation; when "Heatstroke Mode (30℃ and above)" is selected, the vehicle area controller sends a control command to close the windows and set the air conditioning temperature to a comfortable level (e.g., 26℃).

[0075] As another example of the present invention, based on the facial information of the passenger, the passenger information is compared with the passenger information stored in the preset database to determine the passenger's identity information; when the passenger's identity information is a fixed passenger, a special passenger greeting instruction is responded to, and the vehicle area controller is controlled to drive the vehicle's various components to perform the corresponding special greeting actions based on the greeting mode under different weather conditions; when the passenger's identity information is a non-fixed passenger, a basic passenger greeting instruction is responded to, and the vehicle area controller is controlled to drive the vehicle's various components to perform the corresponding basic greeting actions based on the greeting mode under different weather conditions.

[0076] This invention proposes a vehicle intelligent welcome control method. Besides adapting to different weather conditions and performing different welcome operations, it also identifies passengers and provides personalized welcome services based on their individual needs, improving the reliability of the welcome service. Furthermore, it differentiates between fixed and non-fixed passengers, ensuring that fixed passengers receive personalized welcome actions while providing basic services to non-fixed passengers. Specifically, the method uses in-vehicle cameras and other devices to acquire facial information of passengers, compares it with facial data in the in-vehicle database, and determines whether the current passenger is a fixed passenger. Three to five fixed passengers can be selected, each with a specific personalized welcome mode. If the current passenger is determined to be a fixed passenger... Under different weather conditions, the vehicle executes corresponding exclusive welcome commands, with the vehicle area controller controlling the activation of exclusive ambient lighting, adjustment of exclusive air conditioning parameters, adjustment of exclusive rearview mirror position, adjustment of exclusive seat position, and activation of exclusive welcome lights. If the current passenger is not a regular passenger, the basic passenger welcome mode is used, controlling the activation of corresponding basic ambient lighting, adjustment of basic air conditioning parameters, adjustment of basic rearview mirror position, adjustment of basic seat position, and activation of basic welcome lights under different weather conditions. It is worth mentioning that if it is necessary to register the current non-regular passenger as a regular passenger, the passenger's adjustment of various parameters of the basic welcome mode under different weather conditions can be recorded, and the passenger's habits can be recorded as the corresponding exclusive welcome mode, and the passenger's facial data can be updated to the vehicle database.

[0077] This invention proposes a vehicle intelligent welcome control method that senses the distance between passengers and the vehicle and issues different welcome control signals accordingly. This allows for immediate response to passenger needs. Furthermore, by incorporating weather information, it automatically generates and executes welcome actions tailored to individual preferences, significantly enhancing the personalization and intelligence of the passenger experience. It also identifies and adapts to different weather conditions, automatically switching to the most suitable welcome mode and generating appropriate welcome actions for each weather condition, providing reliable welcome services. Additionally, based on passenger attributes, it differentiates between exclusive and basic welcome services, offering reliable and comfortable service. Moreover, by driving various vehicle components to execute welcome service actions through a vehicle area controller, it can quickly switch execution logic to meet different needs, providing reliable and convenient welcome services.

[0078] Example 2

[0079] See Figure 2 , Figure 2 This is a schematic diagram of the vehicle welcome mode control framework structure of a vehicle intelligent welcome control method according to a certain embodiment of the present invention; as shown below. Figure 2 As shown in the figure, the vehicle welcome mode control framework of the intelligent welcome control method for vehicles proposed in this embodiment of the invention includes: a vehicle domain controller VDC, a mobile APP 201, a first body domain controller ZCUFL, a second body domain controller ZCUFR, a third body domain controller ZCUR, a door collision detection module 2018, an entertainment cockpit domain controller 2019, and an air conditioning module 2022.

[0080] The first vehicle body domain controller ZCUFL includes: a first window control service module 202, a first lighting control service module 203, a first seat control service module 204, a first wiper control service module 205, a first door lock control service module 206, and a first rearview mirror control service module 207.

[0081] The second vehicle body domain controller ZCUFR includes: a second window control service module 208, a second lighting control service module 209, a second seat control service module 2010, a second wiper control service module 2011, a second door lock control service module 2012, and a second rearview mirror control service module 2013.

[0082] The third body domain controller ZCUR includes: the third door and window control service module 2014, the third lighting control service module 2015, the third seat control service module 2016, and the third wiper control service module 2017.

[0083] The Entertainment Cockpit Domain Controller 2019 includes: Welcome Mode Switch Service Module 2020 and Voice Reminder Service Module 2021;

[0084] The door collision detection module 2018 is connected to the first body domain controller ZCUFL, and the air conditioning module 2022 is connected to the second body domain controller ZCUFR.

[0085] Based on the above-described vehicle welcome mode control framework, the intelligent vehicle welcome control method proposed in this embodiment of the invention will be explained in detail below:

[0086] S1: Receive the intelligent welcome activation command;

[0087] As an example of an embodiment of the present invention, the intelligent welcome opening command includes: a local hard-wired welcome control signal, a key welcome control signal, or a remote welcome control signal; wherein, the local hard-wired welcome control signal is obtained as follows: when a passenger approaches the vehicle (less than a first preset distance value) and pulls the door handle, the first body domain controller ZCUFL receives the opening command input by the door collision detection module 2018, generates a corresponding local hard-wired welcome control signal, and uses the local hard-wired welcome control signal to open different welcome modes;

[0088] The key welcome control signal is obtained as follows: when the passenger is between the first preset distance value and the second preset distance value, the low-frequency signal broadcast by the base station is received through the remote key, decrypted and authenticated by ID, and then a high-frequency signal is transmitted. After the vehicle is authorized, the corresponding key welcome control signal is generated. The key welcome control signal is used to open different welcome modes.

[0089] The remote welcome control signal is obtained as follows: when the passenger is at a distance greater than the second preset distance value, a smart welcome activation command is sent through the mobile APP. This command is transmitted to the cloud via 4G / 5G / WIFI network and then transmitted to the vehicle domain controller (VDC) based on the Ethernet TCP / IP protocol. The remote welcome control signal is then generated and used to activate different welcome modes.

[0090] In the intelligent vehicle welcome control method proposed in this embodiment, the Ethernet TCP / IP protocol is used for communication transmission. Although the TCP / IP protocol itself does not have a service discovery mechanism, it can be used in combination with other protocols (such as RESTful API) to realize service discovery and invocation. In comparison, the TCP / IP protocol has universality, reliability and wide compatibility, and the technology is more mature.

[0091] It is worth mentioning that when generating the local hard-wired signal control activation mode, it should be confirmed first that the reception control signal is not obtained through key control or remote control.

[0092] S2: Implement different welcoming modes depending on different weather conditions;

[0093] S2.1, Rainy Day Welcome Mode:

[0094] Upon receiving a welcome activation command (first, second, or third welcome activation command) and entering the welcome activation state, the first vehicle domain controller (ZCUFL) collects rainfall and illumination information via the onboard light and rain sensor and sends it to the vehicle domain controller (VDC) via a CAN signal. The CAN network signal can be customized. The VDC interacts with the infotainment cockpit domain controller (2019) to obtain current and future weather characteristics for a specified period (the length of which can be customized, e.g., 24 hours). Based on the received rainfall and illumination information, and the current and future weather characteristics, the VDC determines whether the current environmental conditions meet the preset welcome entry conditions (e.g., rainfall exceeding the rain warning level). The system determines whether to enter the Rainy Day Welcome Mode based on rainfall intensity (e.g., rainfall duration exceeding the warning time, light intensity below the warning value). Rainy Day Mode is further categorized into Rainy Day Mode 1, Rainy Day Mode 2, and Rainy Day Mode 3 (equivalent to "light rain mode," "moderate rain mode," and "heavy rain mode," respectively). When the Vehicle Domain Controller (VDC) determines that the Rainy Day Welcome Mode is ready, it sends a pop-up notification and voice prompt to the vehicle's central control screen via CAN signal, issuing voice reminders such as "Roads are slippery in the rain, please be careful" and "Rainy Day Intelligent Welcome Mode has been automatically activated for you." Once the Rainy Day Welcome Mode is activated, the First Body Domain Controller (ZCUFL), Second Body Domain Controller (ZCUFR), and Third Body Domain Controller (ZCUR) drive the corresponding modules to perform corresponding actions via CAN signal.

For the exclusive welcome mode, it automatically adjusts to the memory position. It is worth mentioning that the opening of the seat module also requires the first seat control service module 204 of the first body domain controller ZCUFL, the second seat control service module 2010 of the second body domain controller ZCUFR, and the third seat control service module 2016 of the third body domain controller ZCUR to obtain the local hard-wire signals of the four doors of the vehicle, and drive the corresponding seat module according to the local hard-wire signals of different doors. For example, if the first seat control service module 204 of the first body domain controller ZCUFL receives the local hard-wire signal of the left front door, it drives the left front seat to adjust its position, etc.

[0096] (2) Door lock module: The first door lock control service module 206 of the first body domain controller ZCUFL drives the left front door lock through CAN signal, the second door lock control service module 2012 of the second body domain controller ZCUFR drives the right front door lock through CAN signal, and the third door and window control service module 2014 of the third body domain controller ZCUR drives the rear door lock through CAN signal, thereby controlling the unlocking and locking of the door lock. It is worth mentioning that when the remote welcome control signal is used to enter the welcome mode, the door lock module does not perform unlocking and locking operations until the first door lock control service module 206 of the first body domain controller ZCUFL receives the opening input from the door collision detection module 2018 and then the door lock module performs unlocking and locking operations. The first door lock control service module 206 of the first body domain controller ZCUFL can drive four door locks to perform unlocking and locking actions at the same time, or can independently control a door lock to perform unlocking and locking actions.

[0099] (5) Wiper module: The first wiper control service module 205 of the first body domain controller ZCUFL drives the front wiper motor and the front washer motor through CAN signal, and the second wiper control service module 2011 of the third body domain controller ZCUR drives the rear wiper and the rear washer motor through CAN signal, thereby realizing the opening and closing of the wipers. It is worth mentioning that, depending on the different rainy weather welcome modes, such as rainy weather mode 1, rainy weather mode 2, rainy weather mode 3, etc. (equivalent to "light rain mode", "medium rain mode" and "heavy rain mode", etc.), the wipers are controlled to achieve low-speed wiping, medium-speed wiping and fast wiping actions.

[0100] In addition, depending on the different vehicle models and passenger needs, modules such as fragrance modules, air suspension modules, horn modules, and AVS modules (Adaptive Variable Suspension) can be configured. The control principle can be the same as the modules mentioned above, so it will not be elaborated here.

[0101] S2.2, Ice and Snow Welcome Mode:

[0102] Upon receiving a welcome activation command (first, second, or third welcome activation command) and entering the welcome activation state, the first body domain controller (ZCUFL), the second body domain controller (ZCUFR), and the third body domain controller (ZCUR) collect temperature information via onboard temperature sensors and transmit it to the vehicle domain controller (VDC) via CAN signals. The CAN network signal can be customized. The VDC interacts with the infotainment cockpit domain controller (2019) to obtain current and future weather characteristics (the length of which can be customized, e.g., 24 hours). Based on the received temperature information and the current and future weather characteristics, the VDC determines the current environmental characteristics. The system determines whether to enter the ice and snow welcome mode based on whether the preset welcome conditions are met (such as the temperature being lower than the preset temperature threshold). Depending on the ambient temperature, it can be divided into "cold mode (10℃~23℃)" and "snow mode (10℃ and below)". When the vehicle domain controller (VDC) determines that the ice and snow welcome mode is met, it sends a pop-up notification and voice prompt to the vehicle's central control screen via CAN signal, issuing voice reminders such as "Please drive carefully in icy and snowy weather" and "Ice and snow intelligent welcome mode has been automatically activated for you". Once the ice and snow welcome mode is activated, the first body domain controller (ZCUFL), the second body domain controller (ZCUFR), and the third body domain controller (ZCUR) drive the corresponding modules to perform corresponding actions via CAN signal.

For the exclusive welcome mode, it automatically adjusts to the memory position. It is worth mentioning that the activation of the seat module also requires the first seat control service module 204 of the first body domain controller ZCUFL and the second body domain controller ZCUFR. The second seat control service module 2010 and the third seat control service module 2016 of the third body domain controller ZCUR obtain the local hard-wire signals of the four doors of the vehicle and drive the corresponding seat modules according to the local hard-wire signals of different doors; for example, if the first seat control service module 204 of the first body domain controller ZCUFL receives the local hard-wire signal of the left front door, it drives the left front seat to adjust its position, etc.; in addition, it also drives the seat to perform heating function according to the specific ambient temperature in different ice and snow welcome modes ("cold mode 10℃~23℃" and "snow mode 10℃ and below"), and can also automatically adjust the heating temperature for the exclusive welcome mode.

[0104] (2) Door lock module: The first door lock control service module 206 of the first body domain controller ZCUFL drives the left front door lock through CAN signal, the second door lock control service module 2012 of the second body domain controller ZCUFR drives the right front door lock through CAN signal, and the third door and window control service module 2014 of the third body domain controller ZCUR drives the rear door lock through CAN signal, thereby controlling the unlocking and locking of the door lock.

It is worth mentioning that the wiper module is not executed in the "cold mode 10℃~23℃", while in the "snow mode (10℃ and below)", the wipers can be controlled to achieve low speed, medium speed and high speed wiper action according to the amount of snow.

[0108] (6) Air conditioning module: In the "cold mode 10℃~23℃", the second body domain controller ZCUFR drives the connected air conditioning module 2022 to turn on the heating function, and adjusts the interior temperature to a suitable temperature (such as 26℃) in real time according to the temperature information collected by the first body domain controller ZCUFL, the second body domain controller ZCUFR and the third body domain controller ZCUR.

[0109] (7) Door handle module: When entering the "Cold Mode 10℃~23℃", the first body domain controller ZCUFL, the second body domain controller ZCUFR and the third body domain controller ZCUR control the left front door handle, the right front door handle and the rear door handle to fold or unfold respectively; when entering the "Snow Mode (10℃ and below)", the first body domain controller ZCUFL, the second body domain controller ZCUFR and the third body domain controller ZCUR control the left front door handle, the right front door handle and the rear door handle to fold or unfold respectively, and control the heating motor to heat up in order to achieve defrosting and ice breaking;

[0110] In addition, depending on the different vehicle models and passenger needs, modules such as fragrance modules, air suspension modules, horn modules, and AVS modules (Adaptive Variable Suspension) can be configured. The control principle can be the same as the modules mentioned above, so it will not be elaborated here.

[0111] S2.3 Summer Welcome Mode:

[0112] Upon receiving a welcome activation command (first, second, or third welcome activation command) and entering the welcome activation state, the first body domain controller (ZCUFL), the second body domain controller (ZCUFR), and the third body domain controller (ZCUR) collect temperature information via onboard temperature sensors and transmit it to the vehicle domain controller (VDC) via CAN signals. The CAN network signal can be customized. The VDC interacts with the infotainment cockpit domain controller (2019) to obtain current and future weather characteristics (the length of the future period can be customized, such as 24 hours). Based on the received temperature information and the current and future weather characteristics, the VDC determines the current environmental characteristics. The system determines whether to enter the "Hot Summer Welcome Mode" based on whether the preset welcome conditions are met (such as temperature exceeding a preset threshold). This mode is categorized into "Hot Mode (23℃~30℃)" and "Heatstroke Mode (30℃ and above)" based on ambient temperature. When the Vehicle Domain Controller (VDC) determines that the "Ice and Snow Welcome Mode" is met, it sends a pop-up notification and voice prompt to the vehicle's central control screen via CAN signal, issuing voice reminders such as "In hot weather, please keep the vehicle ventilated" and "Hot Summer Intelligent Welcome Mode has been automatically activated for you." Once the Hot Summer Welcome Mode is activated, the first body domain controller (ZCUFL), the second body domain controller (ZCUFR), and the third body domain controller (ZCUR) drive the corresponding modules to perform corresponding actions via CAN signal.

[0113] (1) Seat Module: The first seat control service module 204 of the first body domain controller ZCUFL drives the left front seat via CAN signal; the second seat control service module 2010 of the second body domain controller ZCUFR drives the right front seat via CAN signal; and the third seat control service module 2016 of the third body domain controller ZCUR drives the rear seats via CAN signal, thereby controlling the position adjustment of each seat. For the exclusive welcome mode, it automatically adjusts to the memory position. It is worth mentioning that the activation of the seat module also requires the first seat control service module 204 of the first body domain controller ZCUFL, the second seat control service module 2010 of the second body domain controller ZCUFR, and the third seat control service module 2016 of the third body domain controller ZCUR to obtain the four seats of the vehicle. The system receives local hard-wired signals from the doors and drives the corresponding seat modules based on these signals. For example, if the first seat control service module 204 of the first body domain controller ZCUFL receives a local hard-wired signal from the left front door, it will drive the left front seat to adjust its position. In addition, it will drive the seats to perform ventilation functions under different hot weather welcome modes ("Hot mode 23℃~30℃" and "Easy heat mode 30℃ and above") based on the specific ambient temperature. In hot weather mode, the system controls the seats to perform low or medium ventilation functions through local hard-wired signals sent by the third body domain controller ZCUR. In easy heat mode, the system controls the seats to perform medium or high ventilation functions through local hard-wired signals sent by the third body domain controller ZCUR.

It is worth mentioning that when the remote welcome control signal is used to enter the welcome mode, the door lock module does not perform unlocking and locking operations until the first door lock control service module 206 of the first body domain controller ZCUFL receives the opening input from the door collision detection module 2018 and then the door lock module performs unlocking and locking operations. The first door lock control service module 206 of the first body domain controller ZCUFL can drive four door locks to perform unlocking and locking actions at the same time, or can independently control a door lock to perform unlocking and locking actions.

[0115] (3) Lighting Module: The first lighting control service module 203 of the first body domain controller ZCUFL drives the front fog lights, left front welcome lights, and left front ambient lights via CAN signals; the second lighting control service module 209 of the second body domain controller ZCUFR drives the right front welcome lights and right front ambient lights via CAN signals; the third lighting control service module 2015 of the third body domain controller ZCUR drives the rear fog lights, rear welcome lights, and rear ambient lights via CAN signals. It is worth mentioning that different side ambient lights can also be controlled simultaneously or independently according to the exclusive welcome mode to achieve a unique visual control effect; in addition, the corresponding exterior lights and interior lights (such as low beam headlights, high beam headlights, daytime running lights, and dome lights) can be controlled according to different driving needs.

[0116] (4) Rearview mirror module: When the hot summer welcome mode is on, the first rearview mirror control service module 207 of the first body domain controller ZCUFL drives the left front and rear mirrors to unfold and start the heating and defrosting function through CAN signal; the second rearview mirror control service module 2013 of the second body domain controller ZCUFR drives the right front and rear mirrors to unfold and start the heating and defrosting function through CAN signal; it can also automatically adjust the rearview mirrors to the memory position for the exclusive ride welcome mode;

[0117] (5) Window module: The first window control service module 202 of the first body domain controller ZCUFL drives the left front window through CAN signal; the second window control service module 208 of the second body domain controller ZCUFR drives the right front window through CAN signal; the third window control service module 2014 of the third body domain controller ZCUR drives the rear window through CAN signal, thereby realizing the opening and closing of the windows; it is worth mentioning that in hot mode, the first body domain controller ZCUFL, the second body domain controller ZCUFR and the third body domain controller ZCUR can drive the windows to open independently or simultaneously, and in heatstroke mode, the first body domain controller ZCUFL, the second body domain controller ZCUFR and the third body domain controller ZCUR can drive the windows to close independently or simultaneously.

[0118] (6) Air conditioning module: In hot mode or heatstroke mode, and when the windows are closed, the air conditioning module 2022 connected to the second body domain controller ZCUFR turns on the cooling function and adjusts the interior temperature to a suitable temperature (such as 26℃) in real time according to the temperature information collected by the first body domain controller ZCUFL, the second body domain controller ZCUFR and the third body domain controller ZCUR.

[0119] In addition, depending on the vehicle model and passenger needs, modules such as fragrance systems, air suspension systems, horn systems, and AVS (Adaptive Variable Suspension) can be configured. The control principles are the same as those of the modules mentioned above, and will not be elaborated further here. It is worth mentioning that the first body domain controller ZCUFL, the second body domain controller ZCUFR, and the third body domain controller ZCUR can not only control the modules according to commands, but also control the actions of vehicle components.

[0120] This embodiment specifically explains the welcome service control under three weather conditions. In real life, other welcome modes under different weather conditions can be added adaptively according to the location of the passengers. The principle of the welcome service control is the same as that explained in this embodiment, and will not be repeated here.

[0121] S3: Obtain passenger attribute characteristics to generate a unique welcoming function and execute the operation;

[0122] After entering different welcome modes, the system acquires facial information of passengers through in-vehicle cameras, specifically recognizing 3-5 fixed passengers (the number can be customized), and compares this information with the latest facial data in the in-vehicle database to determine the passenger's identity. Based on the passenger's identity, the system then performs the following actions:

[0123] S3.1: When the passenger is a fixed passenger, the first body domain controller ZCUFL, the second body domain controller ZCUFR, and the third body domain controller ZCUR send their facial information to the vehicle domain controller VDC via CAN signal (CAN network signal can be customized). The vehicle domain controller VDC obtains the passenger's identity and associated unique characteristics based on the passenger's facial information and issues a unique welcome mode command to enter a specific exclusive welcome mode, generally named "Passenger Mode 1, Passenger Mode 2, Passenger Mode 3...". For example, Passenger Mode 1 for passenger A: the seat automatically moves back 3cm, and the welcome light pattern is a children's animation and is pink; Passenger Mode 2 for passenger B: the seat automatically moves back 6cm, and the welcome light pattern is a car model and is blue; Passenger Mode 3 for passenger C: the seat automatically moves back 8cm, and the welcome light does not need to be turned on; and so on. Special welcome operations can be customized according to different passengers.

[0124] S3.2: When the passenger is a non-fixed passenger, the first body domain controller ZCUFL, the second body domain controller ZCUFR, and the third body domain controller ZCUR send their facial information to the vehicle domain controller VDC via CAN signal (CAN network signal can be customized). The vehicle domain controller VDC issues a basic welcome mode command to control each module to execute basic passenger settings. These settings can be factory settings or preset basic settings according to local passenger habits. If it is necessary to convert the non-fixed passenger into a fixed passenger, the vehicle domain controller VDC receives parameter update signals sent by each module in real time, records the adjustment of basic welcome mode parameters by each module during the non-fixed passenger's ride, and records the adjustment of basic welcome mode parameters as the new passenger mode. The facial information of the non-fixed passenger is synchronously updated to the vehicle database. Thus, the conversion between non-fixed and fixed passengers is completed.

[0125] This invention proposes a vehicle intelligent welcome control method that, based on conventional recognition technologies such as welcome target recognition and weather environment recognition, adds more complex control strategies and judgment logic. It determines different welcome modes based on different weather conditions and automatically sets corresponding functions to execute exclusive welcome actions based on the attributes of passengers (such as age, gender, and height). This overcomes the shortcomings of low practicality and redundant user experience, ultimately achieving the recognition of environmental and passenger information, executing different welcome strategies for different environments and different passengers, and providing reliable welcome services.

[0126] Example 3

[0127] See Figure 3 , Figure 3 This is a schematic diagram of the module structure of a vehicle intelligent welcome control system according to one embodiment of the present invention. Figure 3 As shown, this embodiment of the invention proposes a vehicle intelligent welcome control system, including: a welcome start command acquisition module 301, a welcome mode recognition module 302, and a vehicle control module 303;

[0128] The welcoming opening instruction acquisition module 301 is used to generate corresponding welcoming opening instructions based on the positional distance between the passenger and the vehicle, in response to different welcoming control signals.

[0129] The welcoming mode recognition module 302 is used to obtain different weather environment information based on the corresponding welcoming start command, and start the welcoming mode under different weather conditions.

[0130] The vehicle control module 303 is used to perform corresponding welcoming actions based on the welcoming mode under different weather conditions.

[0131] This invention proposes a vehicle intelligent welcome control system. A welcome activation command acquisition module senses the distance between passengers and the vehicle, and issues different welcome control signals accordingly, enabling immediate response to passenger needs. Simultaneously, a welcome mode recognition module, combined with weather information, automatically generates and executes welcome actions tailored to individual preferences, significantly enhancing the personalization and intelligence of the passenger experience. It also identifies and adapts to different weather conditions, automatically switching to the most suitable welcome mode through the vehicle control module, generating welcome actions for different weather conditions, and providing reliable welcome services. Furthermore, based on passenger attributes, it distinguishes between exclusive and basic welcome services, providing reliable and comfortable passenger service. In addition, a vehicle area controller drives various vehicle components to execute welcome service actions, enabling rapid switching of execution logic for different modes, providing reliable and convenient welcome services.
