In-Vehicle Communication Device Prediction Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, communication with a central center is often interrupted in environments like tunnels or underground areas, leading to wasteful consumption of resources and power due to repeated and unnecessary data transmission attempts.
Innovation Solution
A communication device with a prediction unit that anticipates communication interruptions based on predetermined information, such as traveling routes or current vehicle positions, and controls data transmission to conserve resources by stopping or limiting data exchange during predicted interruption periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device periodically transmits data to the center or receives data from the center when communication is interrupted, then the communication device can attempt to restore communication, but resources and power are wastefully consumed
Solution Approach 1:
The prediction unit performs preliminary action by predicting communication interruption before it actually occurs. Based on this prediction, the controller proactively stops data transmission in advance, preventing wasteful power consumption during the interruption period while ensuring communication can be restored when the interruption ends.
2Loss of energy
If the communication device stops transmitting data when communication interruption is predicted, then power consumption is reduced, but communication with the center may be delayed
Solution Approach 1:
The communication device employs periodic action by resuming data transmission after a predetermined time elapses following communication interruption. This periodic resumption strategy balances power savings during interruption with timely restoration of communication, preventing indefinite delays while avoiding continuous power consumption.

AI summary
A communication device is provided in a vehicle and is configured to communicate with an external center. The communication device includes a collection unit configured to collect data to be transmitted to the center, a communication unit configured to transmit the data collected by the collection unit to the center, a prediction unit configured to predict an occurrence of communication interruption between the center and the communication unit based on predetermined information, and a controller configured to cause the communication unit to stop transmitting the data in a case where the prediction unit predicts that a predicted time from a current time to the occurrence of communication interruption is less than a first predetermined time.
