Vehicle DCM Access Point Blocking for Faster Remote Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with data communication modules (DCMs) for wireless network connection, the transition from connecting to a local access point to accepting a connection from a user terminal can be hindered by ongoing data transmission, leading to increased waiting times, power consumption, and service response deterioration, especially when attempting remote parking after returning home.
Innovation Solution
The DCM is configured to prevent automatic connection to a predetermined access point for a specified period after the vehicle stops, allowing it to transition into a mode ready to accept a connection from a user terminal, thereby facilitating smooth remote parking operations by avoiding interruptions and reconnection processes.

Engineering Contradiction Analysis
1Reliability
If the DCM automatically connects to a predetermined access point when detected, then network connectivity is established, but connection requests from user terminals are delayed or blocked during ongoing data transmission
Solution Approach 1:
The system performs preliminary actions by detecting vehicle stop conditions and proactively managing access point connection status before user terminal connection requests are made. The controller monitors vehicle stop status and preemptively suspends or prevents automatic connection to access points during periods when remote parking operations are likely, ensuring the DCM is ready to accept user terminal connections without delay.
2Productivity
If the DCM maintains continuous connection to access points for data transmission, then data communication is ensured, but power consumption increases during vehicle stop periods
Solution Approach 1:
The system implements periodic action by evaluating vehicle stop conditions at regular intervals and dynamically adjusting access point connection status. During vehicle stop periods, the controller periodically checks whether the vehicle is stationary and suspends automatic connection to access points, thereby reducing power consumption during intervals when data transmission is not required, while resuming connections when the vehicle is in motion.
3Ease of operation
If the DCM accepts connection from user terminals immediately upon vehicle stop, then remote parking service responsiveness is improved, but conflicts with ongoing access point data transmission occur
Solution Approach 1:
The system extracts the access point connection function from the DCM's operational modes during vehicle stop periods. When the vehicle is detected to be stationary, the controller suspends or prevents the automatic connection function to access points, separating this function from active operation. This allows the DCM to dedicately accept user terminal connections for remote parking operations without interference from access point data transmission, eliminating resource conflicts.
