Description

Technical Field

[0001] This application relates to the intersection of automotive electronics technology and infant care technology, specifically to an automotive infant care system and method. Background Technology

[0002] With the increasing demand for family travel, it is becoming more and more common to travel with infants and toddlers. During the journey, the driver (usually a parent) needs to concentrate on driving and it is difficult to continuously and meticulously observe and care for the infants and toddlers in the back seat. Infants and toddlers may cry due to hunger, needing to urinate or defecate, discomfort, or a poor environment. If they are not responded to in time, it will not only affect the health and comfort of the infants and toddlers, but may also distract the driver and create safety hazards.

[0003] Currently, there are some in-vehicle child monitoring products or solutions on the market. For example, some existing technologies mainly focus on safety monitoring or providing entertainment content through cameras, lacking in-depth monitoring and response to the core physiological states of infants and young children (such as heart rate and body temperature) and excretion status. Other smart monitoring devices designed for static environments (such as infant cribs), while integrating various physiological and environmental sensors, do not consider the special characteristics of dynamic and mobile in-vehicle application scenarios, such as vehicle vibration, power supply, integration with in-vehicle systems (such as air conditioning and CAN bus), and interaction limitations during driving.

[0004] The existing technology has the following shortcomings: (1) The monitoring dimension is single and fails to comprehensively cover the physiological health, excretion needs and emotional behavior of infants and young children; (2) It lacks design for the dynamic characteristics of the vehicle environment and has low system integration; (3) The data processing logic is simple and fails to distinguish the emergency priority of nursing needs; (4) The human-computer interaction method fails to fully consider the continuous needs of driving safety and off-vehicle monitoring.

[0005] Therefore, there is an urgent need for a comprehensive solution that can be deeply integrated into automobiles to provide all-round, intelligent, and high-priority care. Summary of the Invention

[0006] The purpose of this application is to overcome the shortcomings of existing technologies and provide an intelligent car care system and method for infants and toddlers.

[0046] refer to Figure 1 One embodiment of this application proposes an intelligent car care system for infants and toddlers (infants and toddlers typically refer to children aged 0-3 years), which mainly includes the following five core modules: infant and toddler status monitoring module, in-vehicle environment monitoring module, information processing and control module, environment adjustment module, and caregiver interaction module.

[0047] (1) The infant and toddler status monitoring module specifically includes:

[0048] Physiological monitoring unit: Utilizes a flexible wearable photoelectric heart rate strap (worn on the infant's wrist or chest / abdomen) for continuous heart rate monitoring; employs a medical-grade high-precision thermistor temperature sensor (attached to the infant's armpit or forehead, secured with hypoallergenic tape) for real-time body temperature monitoring. Data is transmitted to the information processing and control module via Bluetooth Low Energy (BLE).

[0049] Excretion monitoring unit: A miniature humidity sensor and an ammonia (NH3) sensor are embedded in the absorbent layer of the baby diaper to monitor urination. A metal oxide semiconductor (MOS) odor sensor is installed in a concealed location under or to the side of the baby car seat cushion to directionally monitor the concentration of fecal characteristic gases such as hydrogen sulfide (H2S) to monitor defecation. The sensors are powered wirelessly (e.g., by RFID) or via wired micro-connection.

[0050] Behavioral Status Monitoring Unit: A wide-angle infrared high-definition camera (supporting low-light full-color) is embedded in the roof trim panel directly above the infant seat to capture images of the infant's front. A small directional microphone array is integrated around the camera to directionally pick up the infant's voice, and it features an active noise reduction algorithm to filter out engine and wind noise. This unit has built-in edge computing capabilities, which can initially run a lightweight image recognition model (for recognizing facial expressions and body movements such as closed eyes, open mouth crying, and frowning) and an audio feature extraction algorithm (for analyzing the frequency, intensity, and rhythm of crying sounds), and upload the processed feature data.

[0051] (2) The in-vehicle environment monitoring module reads data directly from the vehicle's body domain controller through the vehicle's standard CAN bus interface, including: air conditioning vent temperature, average in-vehicle temperature and humidity (from integrated sensors), ambient light sensor data, opening and closing status of each window and sunroof, current vehicle speed, etc.

[0052] (3) The information processing and control module is the "brain" of the system and can be integrated into the vehicle cockpit domain controller or used as an independent on-board computing unit. It receives real-time data streams from all the aforementioned monitoring modules. Its core is to run a predefined decision tree and rule engine algorithm, the execution flow of which is as follows: Figure 2 As shown, a strict priority is followed:

[0053] First priority (physiological health): Continuously compare heart rate and body temperature data to see if they exceed preset safety thresholds (thresholds can be personalized according to the infant's age). If any indicator is abnormal, the highest level alarm will be triggered immediately: a red warning window will pop up on the in-vehicle central control screen through the caregiver interaction module and an urgent voice prompt will be issued; if the system determines that the caregiver may have left the vehicle through the in-vehicle camera or the status of the doors, an emergency push notification will be sent to the bound mobile APP at the same time.

[0054] Second priority (emotion and behavior): If physiological indicators are normal, analyze behavioral status data. First, determine if there is persistent crying (based on voice feature analysis). If there is no crying, the process jumps to the third step (third priority) below. If there is crying, proceed to the crying attribution analysis subprocess.

[0055] Third priority (excretion needs): Check the data from the excretion status monitoring unit. If urination or defecation is detected, the system initially determines that the crying is likely caused by excretion discomfort. At this time, the information processing and control module will generate two instructions: one is sent to the environmental adjustment module to start air purification; the other is sent to the caregiver interaction module to generate a text and voice reminder that "the infant may have excreted, it is recommended to check and change the diaper".

[0056] Fourth priority (environmental comfort): If the infant is not crying, or is crying but no excretion is detected, the system comprehensively judges whether the current in-vehicle environment is suitable. For example, if the in-vehicle temperature is higher than the upper limit of the infant's comfort range (e.g., 26°C) and the body temperature shows a slow upward trend, it is determined that cooling is needed; if the ambient light sensor shows that sunlight is directly shining on the infant's face, it is determined that shading is needed. The system can further combine historical data and use machine learning models to optimize the judgment. For example, if an infant cries repeatedly in the car during a specific time period (e.g., 2-3 pm) and the environmental data is normal, the system may learn to prompt the caregiver that "the infant may be entering a period of habitual irritability, and it is recommended to play soothing music."

[0057] When the vehicle is traveling at high speed, the system automatically increases the volume of the voice prompts to ensure the driver can hear them clearly. When ventilation is detected as needed but the windows are closed, the system prioritizes activating the air purifier and displays a message on the central control screen suggesting "opening the windows for ventilation in a safe area." This deep integration of the ventilation system with the vehicle's dynamic driving status enhances the system's applicability and safety in different driving scenarios, making the control strategy more intelligent.

[0058] (4) Environmental regulation module, which receives control commands from the information processing and control module and drives the corresponding vehicle actuators. The environmental regulation module specifically includes:

[0059] Temperature and humidity control unit: Sends target temperature, humidity and airflow commands to the vehicle air conditioning controller via CAN bus to achieve automatic adjustment.

[0060] The temperature and humidity control unit is configured to perform feedforward-feedback composite control based on the infant's body temperature monitoring data and the vehicle's interior temperature and humidity data to maintain a stable body temperature for the infant. The system not only adjusts the air conditioning according to the current interior temperature and humidity, but also proactively lowers the air conditioning set temperature when it detects a slow upward trend in the infant's body temperature (even if the current interior temperature is comfortable), preventing the infant from overheating. This is an intelligent temperature control strategy that combines real-time monitoring and predictive adjustment. This setup achieves a leap from "regulating the environment" to "maintaining the infant's physical comfort," providing more proactive and personalized temperature protection.

[0061] Air quality control unit: controls the switch and speed of the independently installed in-vehicle air purifier, or, if supported, controls the in-vehicle air circulation mode.

[0062] Lighting adjustment unit: Automatically controls the raising and lowering of the sunshade of the side window associated with the infant seat via the vehicle body controller, or adjusts the brightness and color temperature of the rear reading lights / ambient lights.

[0063] (5) Caregiver (the caregiver can be the infant's parent or other caregiver) interaction module, providing a dual interface, specifically including:

[0064] The in-vehicle central control display unit permanently displays key status icons for infants and toddlers (such as heart rate values, body temperature emoticons, and diaper wetness / dryness) on the main screen or quick access cards. It features a dedicated "Infant Monitoring" interface, which can display real-time video, historical graphs (heart rate and body temperature trends), and the system's current activity log (e.g., "14:30 Defecation detected, air purification activated"). All voice prompts are played through the in-vehicle audio system.

[0065] Mobile terminal remote interaction unit: The accompanying mobile APP maintains a connection with the vehicle's infotainment system via cellular network (such as 4G / 5G) or the user's mobile hotspot. The APP's main interface synchronously displays the infant's status and in-vehicle environmental data, supporting real-time video viewing. The APP provides a remote control panel, allowing caregivers to manually adjust the air conditioning temperature, start the air purifier, or turn on the interior lights when leaving the vehicle. When the system triggers any level of alarm or alert, the APP will simultaneously receive push notifications.

[0066] (6) Data storage and analysis module

[0067] Preferably, the in-car infant care system may also include a data storage and analysis module for long-term storage of historical data on the infant's condition and corresponding environmental adjustment records, and for generating a model of the infant's in-car travel habits and comfort. Specifically, the system records the infant's sleep time, preferred temperature range, and reactions to different light intensities during each trip. Based on this data, the system can generate personalized care strategies for different infants, such as automatically suggesting or implementing methods to create a sleep environment at their usual nap time. This gives the system learning and adaptive capabilities, evolving from a general care logic into a personalized intelligent care companion, further improving the accuracy of care and the infant's comfort experience.

[0068] refer to Figure 3 One embodiment of this application proposes a car-based infant care method based on the aforementioned car-based infant care system, specifically including:

[0069] S1. Real-time monitoring of infants' physiological, excretory and / or behavioral states, and acquisition of in-vehicle environmental parameters.

[0070] Specifically, the system continues to operate while the vehicle is in motion. The infant status monitoring module reports: heart rate 120 beats / min (normal), body temperature 37.5 ℃ (normal to slightly elevated trend), humidity sensor signal surge (urination), and the microphone detected a slight sobbing sound. The in-vehicle environment monitoring module reports: in-vehicle temperature 28 ℃, strong light.

[0071] S2. According to the preset priority order, the crying information, excretion status and in-vehicle environmental parameters in the physiological state and behavioral state are analyzed and comprehensively judged in turn to obtain a comprehensive judgment result.

[0072] Specifically, the information processing and control module handles information according to priority: Level 1, normal physiological function; Level 2, mild crying detected; Level 3, urination detected. Therefore, the current situation is determined to be: the infant is crying mildly due to discomfort from urination and the heat inside the vehicle.

[0073] S3. Based on the comprehensive judgment results, generate corresponding environmental adjustment control instructions and / or caregiver reminder information.

[0074] Specifically, the information processing and control module then generates a set of instructions: (1) sends an instruction to the environmental adjustment module, requesting that the target temperature of the air conditioner be set to 24 ℃; (2) sends a text and voice reminder to the caregiver interaction module: "The baby has wet his / her diaper and the car is hot. The air conditioner has been automatically turned down. Please check the diaper when convenient."

[0075] S4. Execute the environmental adjustment control command to automatically adjust the in-vehicle environment, and present the infant's status information, environmental parameters, and caregiver reminder information to the caregiver through the in-vehicle central control display unit and / or mobile terminal remote interaction unit.

[0076] Specifically, the environmental control module adjusts the air conditioning. The caregiver interaction module displays a reminder text and voice broadcast on the central control screen, while simultaneously pushing the reminder to the caregiver's mobile app. After hearing the voice message, the caregiver understands that the situation has been partially addressed automatically (cooling down) and knows that the diaper needs to be disposed of after safely parking, thus alleviating anxiety and allowing them to focus on driving.

[0077] In one embodiment, the system detects that the infant's body temperature rapidly rises to 38.2 ℃ (exceeding the threshold), and the heart rate also increases. The information processing and control module immediately triggers the first-priority alarm. A red warning pops up on the central control screen: "Infant's body temperature is too high!", and a continuous buzzing alarm sounds. The mobile app simultaneously receives a push notification: "Urgent: Infant's body temperature is abnormal, please check immediately!" The system may also automatically adjust the vehicle's interior temperature to a lower level (e.g., 22 ℃) for physical cooling. This series of actions ensures that the most urgent health risks are communicated to the guardian in the most prominent way and through all available channels as soon as possible.

[0078] This application achieves the following beneficial effects by constructing a closed-loop system integrating multi-dimensional monitoring, intelligent decision-making, automatic adjustment, and two-way interaction:

[0079] 1. Enhanced Comprehensiveness and Timeliness of Care: The infant status monitoring module comprehensively collects physiological, excretory, and behavioral data, enabling a holistic understanding of infants' health and needs. The information processing and control module employs priority-based decision-making logic to ensure that the most urgent situations, such as abnormal heart rate, are identified and responded to immediately, avoiding delays that may result from simple parallel processing.

[0080] 2. Adaptive adjustment of in-vehicle environment: The system deeply integrates a vehicle environment monitoring and adjustment module, which can automatically and accurately adjust the in-vehicle microenvironment based on the infant's real-time status (such as starting purification due to excretion) or predictive needs (such as adjusting the temperature based on body temperature trends), significantly improving the comfort of infants in the vehicle.

[0081] 3. User-friendly and safe human-computer interaction: The caregiver interaction module provides dual channels: the in-vehicle central control screen and a remote mobile app. Caregivers can quickly obtain key information (such as video feeds) through the central control screen without significantly shifting their gaze; caregivers away from the vehicle can maintain uninterrupted monitoring and remote intervention via their mobile phones. This design balances the needs of driving safety and continuous monitoring.

[0082] 4. High system integration and strong reliability: The system is built on the vehicle power supply and communication network (such as CAN bus and Ethernet), and is deeply integrated with the vehicle's electronic and electrical architecture, ensuring stable operation, fast response and long-term reliability, and meeting automotive-grade requirements.

[0083] The embodiments of car-based infant care methods and car-based infant care systems are identical or related in technical concept, and can be referenced and learned from each other in terms of technical details and technical effects, which will not be repeated here.
