Communication Control Device for Digital Twin Frequency Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems face challenges in maintaining the quality of digital twins while managing communication costs, as frequent communication with multiple vehicles leads to bandwidth compression and increased costs, potentially degrading the quality of digital twin data due to processing delays.
Innovation Solution
A communication control device dynamically adjusts the frequency of communication with vehicles based on their distance from surrounding objects and speed, using a control unit to manage communication patterns, ensuring higher frequency for closer or faster vehicles to prioritize digital twin quality and reducing frequency for distant or slower vehicles to minimize costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the server performs communication with all vehicles at a uniform high frequency, then the quality of digital twin data is improved, but the communication cost increases and communication band is compressed
Solution Approach 1:
The patent applies local quality by differentiating communication frequencies based on individual vehicle conditions. Instead of uniform high-frequency communication with all vehicles, the system adjusts communication frequency locally for each vehicle according to its distance from surrounding objects and speed, thereby maintaining digital twin quality where needed while reducing overall communication cost.
Solution Approach 2:
The patent implements dynamics by making communication frequency adjustable and adaptive rather than fixed. The control unit dynamically changes communication frequency based on real-time vehicle states (distance to surrounding objects and speed), allowing the system to optimize between digital twin quality and communication cost according to changing conditions.
2Loss of energy
If the server reduces communication frequency to suppress communication cost, then communication cost is reduced, but the quality of digital twin deteriorates due to processing delay
Solution Approach 1:
The patent prevents uniform reduction of communication frequency by implementing local quality adjustments. Each vehicle receives customized communication frequency based on its specific situation - vehicles closer to surrounding objects or moving faster maintain higher communication frequencies to preserve digital twin quality, while distant or slow-moving vehicles reduce frequency to lower communication cost.
Solution Approach 2:
The patent employs feedback mechanisms where the control unit continuously monitors vehicle states (distance to surrounding objects and speed) and adjusts communication frequency accordingly. This feedback loop ensures that communication frequency is optimized based on actual vehicle conditions, preventing digital twin quality deterioration when cost reduction is needed.
3Measurement precision
If the server increases communication frequency for vehicles close to surrounding objects, then the quality of digital twin is secured, but the overall communication load increases
Solution Approach 1:
The patent applies local quality by concentrating communication resources on vehicles that need them most - those close to surrounding objects or moving faster. Instead of uniformly increasing communication frequency for all vehicles, the system selectively increases frequency only for specific vehicles based on their local conditions, thereby securing digital twin quality for critical vehicles while limiting overall communication load increase.
Solution Approach 2:
The patent implements partial action by applying high communication frequency only to the extent necessary for specific vehicles. Rather than maintaining high frequency for all vehicles, the system applies excessive communication frequency selectively to vehicles close to surrounding objects or moving faster, where it is most needed for maintaining digital twin quality, while using lower frequency for other vehicles.

AI summary
A communication control device for performing communication with a plurality of vehicles, comprising: a communication unit that performs communication including acquisition of vehicle data with a plurality of vehicles; a database that stores data for forming a digital twin that is time-synchronized with a real space on a virtual space based on vehicle data acquired by the communication unit; and a control unit that controls a frequency of communication performed by the communication unit, wherein when there is a first vehicle in which a distance from a surrounding object is less than a first threshold value on the digital twin, the control unit increases a frequency of communication performed between the first vehicle and the surrounding object than when the distance between the first vehicle and the surrounding object is equal to or greater than the first threshold value.
