Description

Technical Field

[0001] The present invention relates to the field of intelligent driving technology, and in particular to a vehicle adaptive welcoming method, system, medium and equipment. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In recent years, with the rapid development of technologies such as the Internet of Things, artificial intelligence, big data, and cloud computing, the automotive industry is undergoing a profound transformation, transforming from traditional mechanical transportation to an intelligent mobile platform that integrates advanced information technology. As an important part of the automotive user experience, the welcome system is also undergoing a revolutionary upgrade to better integrate into the smart car ecosystem. The existing welcome system can adaptively adjust the lights, identify the distance between the car key and the car, and thus determine whether the owner is approaching, and make light and voice announcements in advance. However, the existing vehicle welcome system only welcomes the driver, but ignores the comfort of the passengers, and cannot adaptively adjust the in-vehicle facilities according to the number and weight of the passengers. Therefore, how to achieve adaptive welcome control when multiple people are riding in the vehicle has become one of the technical problems that need to be solved in the existing technology. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a vehicle adaptive welcoming method, system, medium and equipment, which can judge the number and characteristics of vehicle passengers in real time, and adaptively adjust the in-vehicle facilities such as air conditioning, ventilation, broadcasting or lighting according to the judgment results, so as to improve the comfort of passengers.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A first aspect of the present invention provides a vehicle adaptive welcoming method, comprising the following steps:

[0007] Detect the user approaching the vehicle and control the vehicle to start the welcome mode;

[0008] After all passengers are seated, identify the location, quantity and quality of passengers;

[0009] Adaptively adjust the facilities in the vehicle according to the recognition results, including adjusting the air conditioning temperature and ventilation volume according to the number and quality of passengers; adjusting the interior lighting according to the position of the passengers and the external environmental conditions;

[0010] The vehicle is inspected for safety procedures before departure, and passengers are reminded to depart after the inspection is completed.

[0011] Furthermore, the process of detecting the user approaching the vehicle is as follows:

[0012] Set distance threshold;

[0013] Use Bluetooth technology to detect the distance between the vehicle key held by the user and the vehicle;

[0014] When the distance between the key and the vehicle is less than the set distance, it is determined that the user is approaching the vehicle.

[0015] Furthermore, the steps of controlling the vehicle to start the welcome mode include:

[0016] Obtain the external environmental conditions and vehicle key location, and turn on the interior lights in advance;

[0017] Adjust the interior lighting based on the external environmental conditions;

[0018] Voice prompts based on environmental conditions and vehicle key position.

[0019] Furthermore, the external environmental conditions include: abundant light conditions, dim light conditions, and heavy rainfall conditions.

[0020] Furthermore, the specific steps for adjusting the air conditioning temperature and ventilation volume according to the number and quality of passengers are as follows:

[0021] Obtain the number and mass of passengers and calculate the heat dissipation of the human body;

[0022] Calculate the required air conditioning temperature based on the heat dissipation of the human body;

[0023] Calculate the required ventilation volume based on the number of passengers.

[0024] Furthermore, the vehicle's pre-departure safety procedures include:

[0025] Detect whether the doors and trunk are closed;

[0026] Check whether the seat belt is worn properly;

[0027] Check whether all passengers are seated properly.

[0028] When the Bluetooth key is within 10 meters of the vehicle, the vehicle is activated, and the sensor monitors the key position. After identifying the key position, the environmental sensor determines the weather conditions. If it is judged to be daytime, all lights are turned off. To facilitate the owner to find the vehicle, the external speaker is used to voice prompt the owner's specific location, such as "I am behind the left". When the vehicle is parked for a long time, it is in a closed state, which may cause the air quality in the car to deteriorate. Therefore, with the help of the external temperature sensor, the vehicle predicts and automatically adjusts the internal climate to the optimal state. If it is judged to be a night environment, the LED lights under or around the rearview mirror will be activated to directly illuminate the ground to the area under the feet of the owner, and the light source on the ground can move with the movement of the owner. Specifically, the projection positioning of the light source is realized by the position of the Bluetooth key, and then the effect of the light source on the ground moving with the movement of the owner can be achieved. Therefore, no matter which direction the owner approaches the vehicle, the light can just illuminate its path, greatly reducing the risk of tripping due to poor vision. If it is judged to be a rainy environment, the LED lights under or around the rearview mirror will be activated to directly illuminate the ground to the area under the feet of the owner, and the light source on the ground can move with the movement of the owner. Through sensors (such as radar, cameras or special moisture detection sensors) and advanced image recognition algorithms, it can identify areas of water on the ground and provide voice prompts to the owner of the road conditions, such as "there is a pothole ahead."

[0029] If the key is detected to be 2 meters away from the car, the owner's identity will be recognized and confirmed in all environments (fingerprint or face, etc.). After successful verification, the car will automatically log in to the corresponding owner's account. At night, the LED lights under or around the rearview mirror are turned off, and the welcome light is on. The owner can enjoy the welcome light set according to his or her preferences, which increases the vehicle's sense of technology and luxury, and makes each time you get in the car more pleasant. In rainy weather, the air conditioning defogger, rearview mirror heating, and front wiper will be automatically turned on to quickly clear the rain from the windows and rearview mirrors to ensure a clear driving field of vision, and the seat ventilation or heating will be turned on in advance according to the outside temperature.

[0030] When the driver enters the car, the car audio system will issue a cheerful voice welcome in the daytime environment, and display a specially customized sunny theme welcome interface or animation on the car screen according to the user's preferences, and send cleaning suggestions to the owner in a timely manner. In the night environment, the ambient light is turned on, and a relaxing voice welcome and night driving precautions are played. In the rainy environment, the ambient light is turned on, and a warm voice welcome and rainy driving precautions are played. When the system detects that the driver sits on the seat, the door automatically closes, and the air conditioner on the left side of the steering wheel is turned on to dry the rain on the umbrella. When the umbrella reaches the preset dryness standard, the air outlet is automatically closed or restored to the normal climate control mode.

[0031] A second aspect of the present invention provides a vehicle adaptive welcoming system, comprising:

[0032] A mode activation module is configured to detect a user approaching the vehicle and control the vehicle to activate a welcome mode;

[0033] A passenger detection module is configured to identify the position, quantity and quality of passengers after all passengers are seated;

[0034] The adaptive welcoming module is configured to adaptively adjust the facilities in the vehicle according to the recognition results, wherein the air conditioning temperature and ventilation volume are adjusted according to the number and quality of passengers; the interior lighting is adjusted according to the position of the passengers and the external environmental conditions;

[0035] The safety inspection module is configured to perform safety procedure inspection on the vehicle before departure and to remind passengers to depart after the inspection is completed.

[0036] The third aspect of the present invention provides a welcoming system for the vehicle adaptive welcoming method according to the first aspect, comprising:

[0037] Environmental sensor, used to receive information about environmental parameters inside and outside the vehicle;

[0038] Mode converter, used to switch between different welcoming modes;

[0039] The central processing unit is used to receive information transmitted by the environmental sensor, analyze and process it according to the preset threshold value and time rules, and generate a command based on the analysis result and send it to the device controller;

[0040] The device controller is used to receive commands sent by the central processing unit and control the facilities and mode conversion in the vehicle according to the commands.

[0041] A fourth aspect of the present invention provides a medium having a program stored thereon, which, when executed by a processor, implements the steps of the vehicle adaptive welcoming method as described in the first aspect of the present invention.

[0042] The fifth aspect of the present invention provides a device, including a memory, a processor, and a program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps in the vehicle adaptive welcoming method as described in the first aspect of the present invention are implemented.

[0043] One or more of the above technical solutions have the following beneficial effects:

[0044] The present invention discloses a vehicle adaptive welcoming method, system, medium and equipment. In order to overcome the single welcoming mode in the existing welcoming system, the present invention sets a plurality of welcoming modes, which can be adaptively switched according to the number of passengers and environmental conditions, and can detect the number of people in the vehicle, and adaptively adjust the air-conditioning temperature, light position and ventilation volume, so as to improve the comfort of all passengers.

[0045] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will become obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0053] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or their combinations;

[0054] Embodiment 1:

[0055] Embodiment 1 of the present invention provides a vehicle adaptive welcoming method, such as Figure 1 As shown, the following steps are included:

[0056] Step 1: Detect when a user approaches the vehicle and control the vehicle to start the welcome mode.

[0057] The specific steps are as follows:

[0058] Step 1.1: Detect user approaching the vehicle.

[0059] Step 1.1.1: Set the distance threshold.

[0060] Step 1.1.2: Use Bluetooth technology to detect the distance between the vehicle key held by the user and the vehicle.

[0061] Step 1.1.3: When the distance between the key and the vehicle is less than the set distance, it is determined that the user is approaching the vehicle.

[0062] In this embodiment, the distance threshold can be set according to the actual situation, and different response modes can be customized according to the set threshold, such as double flash effect, sound effect or voice broadcast, etc. The distance is a straight-line distance.

[0063] Step 1.2: Control the vehicle to start the welcome mode, such as Figure 2 As shown, the system first performs initialization to determine whether to enter the automatic setting mode. If not, the welcome mode set by the customer is loaded. If yes, the weather type is determined. If it is rainy, the rainy welcome mode is loaded. If it is daytime, the daytime welcome mode is loaded. If it is night, the night welcome mode is loaded. The weather type is determined by the external environmental conditions.

[0064] Step 1.2.1: Obtain the external environmental conditions and the location of the vehicle key, and turn on the interior lights in advance;

[0065] Step 1.2.2: Adjust the interior lighting based on the exterior conditions.

[0066] The external environmental conditions include: abundant light conditions, dim light conditions and heavy rainfall conditions.

[0067] Step 1.2.3: Voice prompts based on environmental conditions and vehicle key location.

[0068] In a specific implementation, there are the following welcoming modes:

[0069] 1. If Figure 3 As shown, the car welcome mode under sufficient lighting conditions:

[0070] The light sensor senses the intensity of external light. When the ambient light is sufficient, the effect of the welcome light is greatly weakened. Therefore, when the light is sufficient, the welcome light is turned off, which saves energy and avoids unnecessary light pollution. When the Bluetooth key is within 10 meters of the vehicle, the sensor detects the position of the key and gives a voice prompt to the owner. For example, if the key is detected in the right front of the vehicle, the voice broadcast "I am in the left rear" will be broadcast to remind the owner. The volume is dynamically adjusted according to the surrounding noise level detected by the sound sensor to ensure that the owner can easily find the vehicle even in a noisy environment. When the vehicle is parked for a long time, it is in a closed state, which may cause the air quality in the car to deteriorate. Therefore, with the help of the external temperature sensor, the vehicle predicts and automatically adjusts the internal climate to the best state. For example, in the pleasant range of 10℃ to 25℃, it is preferred to use the smart sunroof or slightly open the side windows to introduce natural ventilation, combined with an efficient air purification system to maintain the fresh air in the cabin; in the face of extreme temperatures (below 10℃ or above 25℃), the air conditioning system is activated in advance to ensure a comfortable temperature when boarding. When the Bluetooth key is within 2 meters of the vehicle, the owner's identity is confirmed through fingerprint recognition. After successful verification, the vehicle will automatically log in to the corresponding owner's account, and the vehicle's various settings (such as seat position, rearview mirror angle, common navigation destinations, entertainment preferences, etc.) will be automatically adjusted according to the personalized configuration of the account. After entering the vehicle, the car audio system will issue a cheerful voice welcome, and display a specially customized sunny theme welcome interface or animation on the car screen according to the user's preferences. In addition, the body cleanliness monitoring sensor is used to evaluate the cleanliness of the vehicle and send cleaning suggestions to the owner in a timely manner.

[0071] 2. If Figure 4 As shown, the car welcome mode in low light conditions:

[0072] The light sensor senses the intensity of external light. When the ambient light is dark, the Bluetooth key is within 10 meters of the vehicle. The sensor detects the key position. After identifying the key position, the LED lights under or around the rearview mirror will be activated, directly illuminating the ground to the area under the owner's feet. The light source on the ground can move with the owner's movement, helping the owner to quickly find the parking location of the vehicle and avoid accidents such as tripping due to unclear road conditions during the search process. When the Bluetooth key is within 2 meters of the vehicle, the LED lights under and around the rearview mirror are turned off, the welcome light is on, and the system adjusts the brightness, color and animation effects according to environmental changes to create a warm or eye-catching welcome scene. In addition to basic brightness and color adjustments, the system can also display different animation effects according to preset programs or learn user preferences, including but not limited to flowing turn signals, gradient welcome sequences or specific pattern projections, etc., aiming to create a unique welcome scene and increase the interactivity and fun of the vehicle; the system supports the preset exclusive lighting scenes for special holidays or anniversaries to add a sense of ceremony and personalized experience. The car computer can confirm the owner's identity through the fingerprint recognition on the key. After successful verification, the car computer will automatically log in to the corresponding owner's account. The vehicle's various settings (such as seat position, rearview mirror angle, common navigation destinations, entertainment preferences, etc.) will be automatically adjusted according to the personalized configuration of the account. After entering the vehicle, the ambient light turns on, the car audio system issues a warm voice welcome, and plays night driving precautions. According to the user's preferences, a specially customized night-themed welcome interface or animation is displayed on the car screen.

[0073] 3. If Figure 5 As shown, the car welcome mode under heavy rain conditions:

[0074] When the rain sensor detects heavy rainfall, the Bluetooth key is within 10 meters of the vehicle, and the sensor detects the key position. After identifying the key position, the LED lights under or around the rearview mirror will be activated, directly illuminating the ground to the area under the owner's feet, and the light source on the ground can move with the owner's movement. And through sensors (such as radar, camera or special moisture detection sensor) and advanced image recognition algorithms to identify the water accumulation area on the ground, voice prompts the owner "there is a water pit ahead", and the volume is increased as appropriate according to the amount of rainfall and the surrounding environment. It should be noted that the sensor is installed on the vehicle and the technical area is identified through the existing image recognition algorithm, which will not be repeated here. When the Bluetooth key is within 2 meters of the vehicle, the owner's identity is confirmed through fingerprint recognition. After successful verification, the car will automatically log in to the corresponding owner's account, and the vehicle's various settings (such as seat position, rearview mirror angle, common navigation destinations, entertainment preferences, etc.) will be automatically adjusted according to the personalized configuration of the account. In addition, the air conditioning defogger, rearview mirror heating, and front wiper are automatically turned on to quickly clear the rain from the windows and rearview mirrors to ensure a clear driving field of vision. The seat ventilation or heating is turned on in advance according to the outside temperature, so that the owner can feel the warm and dry comfortable environment as soon as he enters the car. After entering the vehicle, the ambient light is turned on, the car audio system issues a warm voice welcome, and plays the precautions for driving in the rain. According to the user's preferences, a specially customized rainy day theme welcome interface or animation is displayed on the car screen. When the system detects that the driver sits on the seat, the door closes automatically. There is an air conditioning outlet on the left side of the steering wheel. When the sensor detects that a wet umbrella is placed in the door guard, the air conditioning outlet automatically opens to dry the rain on the umbrella. The sensor can also monitor the dryness of the umbrella. Once the preset dryness standard is reached, the outlet is automatically closed or restored to the normal climate control mode.

[0075] Step 2: After all passengers are seated, identify the location, quantity and quality of the passengers.

[0076] In a specific implementation, a weight sensor and a temperature sensor are arranged under the seat of the vehicle, and the number of passengers is identified by weight changes. In order to prevent misjudgment caused by weight changes caused by placing items, the temperature sensor is prevented from performing temperature detection, and only when the temperature and weight change at the same time is it determined that there is a passenger sitting at the position. The sensor at each position transmits the obtained passenger position and mass to the vehicle controller.

[0077] Step 3: Adaptively adjust the facilities in the vehicle according to the recognition results.

[0078] Step 3.1: Adjust air conditioning temperature and ventilation volume according to the number and quality of passengers.

[0079] Step 3.1.1: Obtain the number and mass of passengers and calculate the heat dissipation of the human body.

[0080] Q 总 =Aσ(T1 4 -T0 4 ).

[0081] Among them, Q 总 is the total heat dissipation (W / m 2 ), A is the human body surface area (m 2 ), σ is the Stefan-Boltzmann constant, T1 is the body surface temperature (K), and T0 is the ambient temperature (K).

[0082] Step 3.1.2: Calculate the required air conditioning temperature based on the heat dissipation of the human body.

[0083] According to the human thermal comfort theory, the required air conditioning temperature can be calculated by the following formula:

[0084] T 空调 =M-W+E+C+R / Q 总 .

[0085] Where: T 空调 is the required air conditioning temperature (℃), M is the human energy metabolism rate (W / m 2 ), W is the mechanical work done by the human body (W / m 2 ), E is the heat carried away by evaporation of sweat and exhaled water vapor (W / m 2 ), C is the convective heat transfer between the outer surface of the clothed body and the environment (W / m 2 ), R is the radiation heat exchange between the outer surface of the clothed body and the surrounding surface (W / m 2 ), Q 总 is the total heat dissipation (W / m 2 ).

[0086] Among them, parameters such as M, W, E, C, R, and A are estimated based on the passenger mass, and the estimation method adopts the existing method for estimation.

[0087] Step 3.1.3: Calculate required ventilation based on the number of occupants.

[0088] The ventilation volume calculation formula is: L=nV.

[0089] Where: L is the ventilation volume (m 3 / h), n is the number of cabin ventilation times (times / h), V is the cabin volume (m 3 ).

[0090] Since human breathing causes an increase in carbon dioxide concentration, the number of times the compartment is ventilated is related to the number of people. The deep learning model is used to learn the relationship between the number of times the compartment is ventilated and the number of people. The relationship between the number of people and the number of compartment ventilation is substituted into the ventilation volume calculation formula to obtain the required ventilation volume.

[0091] Step 3.2: Adjust the interior lighting based on the position of the passengers and the external environmental conditions.

[0092] Step 3.2.1: Get the passenger's seat position and turn on the lights according to the passenger's seat position.

[0093] According to the passenger position located by the sensor, the lights at the corresponding position are turned on, and the lights at the position without passengers are not turned on. This function is applicable to vehicles with multiple position lights.

[0094] Step 3.2.2: Adjust the light brightness according to the external environment conditions.

[0095] The external environmental conditions include: abundant light conditions, dark light conditions, and heavy rain conditions. The lighting is adaptively adjusted according to the external light intensity transmitted back by the sensor.

[0096] Step 4: Carry out a safety procedure check on the vehicle before departure and remind passengers to depart after the check is completed.

[0097] Step 4.1: Perform a pre-departure safety procedure check on the vehicle.

[0098] Step 4.1.1: Check whether the doors and trunk are closed.

[0099] Step 4.1.2: Check whether the seat belt is worn properly.

[0100] Check whether the seat belts are fastened to determine whether the passengers are wearing them properly.

[0101] Step 4.1.3: Check whether all passengers are seated properly.

[0102] If the weight sensor changes drastically several times in a short period of time after a passenger is seated, it can be determined that the passenger is not seated properly, such as when a passenger stands up or a child jumps on the seat. At this time, a voice announcement is required to remind the passenger.

[0103] Step 4.2: After the test is completed, the passenger will be reminded to depart.

[0104] According to the test results, the passenger is reminded. For example, if the safety procedure test is passed, a voice prompt such as "Ready to go, please sit down" is issued. If it is detected that the door is not closed, a voice prompt such as "The passenger door is not closed" is issued.
