Vehicle Communication Switching Based on Occupant Throughput Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limitations of 5G mmWave communication in vehicles, including narrow service area, blockage by obstacles, limited mobility support, and increased power consumption, make it inefficient for default use in vehicle-mounted electronic devices, particularly for V2X communication requiring high data transmission rates and low latency.
Innovation Solution
An electronic device on a vehicle monitors the number of occupants and their operation patterns to predict data throughput, switching between 5G mmWave and other communication schemes like 5G Sub 6, LTE, or 3G based on predicted throughput needs, reducing power consumption and preventing heating issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 5G mmWave communication scheme is used to achieve high data transmission rate and low latency, then V2X communication performance is improved, but power consumption increases and heating problems occur
Solution Approach 1:
The patent implements dynamic communication scheme selection that adapts to real-time vehicle conditions. The system switches between 5G mmWave and alternative communication schemes (5G Sub 6, LTE, 3G) based on occupancy status, operational mode, and environmental factors, thereby optimizing power consumption while maintaining adequate data transmission performance
Solution Approach 2:
The system changes communication parameters by selecting different communication schemes based on predicted data throughput requirements. When high data transmission rate is needed, 5G mmWave is selected; when lower throughput suffices, alternative schemes with lower power consumption are chosen, thus adjusting the power-performance parameter balance
2Productivity
If 5G mmWave communication scheme is used to achieve high data transmission rate, then V2X communication performance is improved, but service area is limited due to narrow beam characteristic
Solution Approach 1:
The system dynamically selects communication schemes based on the vehicle's operational context and environmental conditions. When the vehicle is in areas with poor 5G mmWave coverage or when broad coverage is needed, the system switches to alternative schemes with wider service areas, thus adapting the communication approach to spatial requirements
3Productivity
If 5G mmWave communication scheme is used to achieve high data transmission rate, then V2X communication performance is improved, but communication reliability is reduced due to blockage by obstacles
Solution Approach 1:
The system uses an intermediary decision-making mechanism that evaluates multiple factors (occupancy status, operational mode, signal quality) before selecting a communication scheme. This intermediary layer allows the system to choose more reliable communication paths when obstacles are detected or when environmental conditions suggest potential blockages
4Productivity
If 5G mmWave communication scheme is configured as default to ensure high data transmission rate, then V2X communication performance is improved, but heating problems occur due to continuous high power operation
Solution Approach 1:
The system implements periodic evaluation of communication needs based on changing vehicle conditions (occupancy changes, operational mode transitions). Rather than continuous high-power operation, the system periodically assesses whether 5G mmWave is necessary and switches to lower-power schemes when adequate performance can be achieved with alternative communication methods
Solution Approach 2:
The communication system serves itself by autonomously selecting appropriate communication schemes based on predicted data throughput requirements and real-time conditions, eliminating the need for continuous high-power operation and thereby reducing self-heating while maintaining adequate performance

AI summary
An electronic device mounted on a vehicle and an operating method of the electronic device are provided. The electronic device monitor the number of occupants riding in the vehicle, obtain communication access information includes information about the number of connectors accessing a communication module from among the occupants and information about an amount of data use through the communication module, recognize an operation pattern of the occupants, by using an occupant monitoring system (OMS), predict a data throughput to be transmitted and received through the communication module, by using the number of occupants, the obtained communication access information, and the operation pattern of the occupants, and determine, based on the predicted data throughout, whether to change a first communication scheme in use to a second communication scheme, which is fifth generation (5G) millimeter wave (mmWave) communication.
