Vehicle Communication Switching by Parking Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted communication devices fail to properly switch between wireless communication for ITS and wireless LAN communication, leading to improper stoppage of ITS communication, which can result in inadequate safety support systems and reduced convenience for users.
Innovation Solution
A vehicle-mounted communication device equipped with antennas and wireless units capable of switching between ITS and wireless LAN frequencies, a parking determination unit, and a storage unit to manage communication based on the vehicle's parking position, ensuring seamless switching between the two communication modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless communication for ITS is stopped when the vehicle is parked, then power consumption is reduced, but safety support functionality is lost when parked on the road
Solution Approach 1:
The patent applies local quality by differentiating the communication behavior based on the parking location. When parked on the road, ITS communication continues to ensure safety support functionality. When parked in a safe place like a parking lot, ITS communication is stopped to reduce power consumption. This location-dependent quality adjustment resolves the contradiction between power savings and safety functionality.
Solution Approach 2:
The patent implements dynamic switching between communication modes based on real-time conditions. The system dynamically determines whether the vehicle is parked on the road or in a safe place, and adjusts the communication state accordingly. This dynamic adaptation allows the system to optimize power consumption while maintaining safety functionality when needed.
2Loss of energy
If wireless LAN communication is used when parked, then power consumption is reduced, but user convenience is impaired due to improper switching
Solution Approach 1:
The patent applies self-service by implementing automatic determination of parking location and automatic switching between communication modes. The system independently judges whether the vehicle is parked on the road or in a safe place and autonomously selects the appropriate communication mode without requiring user intervention. This eliminates the burden on users to manually manage communication switching while optimizing power consumption.
3Reliability
If wireless communication for ITS is continuously performed, then safety support is maintained, but power consumption increases
Solution Approach 1:
The patent applies local quality by adjusting communication behavior based on specific parking locations. In locations where safety support is critical (parked on the road), ITS communication continues. In locations where safety risk is low (parked in safe places), communication is stopped to save power. This spatially differentiated approach resolves the contradiction between continuous safety support and power consumption.

AI summary
A vehicle-mounted communication device includes wireless units 3a and 3b that switch a frequency that performs wireless communication with antennas 2a and 2b between a frequency for wireless communication for ITS and a frequency for wireless LAN communication, a parking determination unit 6 that determines whether or not a vehicle is parked, a parking position storage unit 6a that stores as a parking position a position where it is determined that the vehicle is parked by the parking determination unit 6, and a wireless control unit 4 that controls the wireless units 3a and 3b to perform the wireless communication for ITS with the antennas 2a and 2b when the vehicle is running, and switch the wireless communication for ITS or the wireless LAN communication to be performed with the antennas 2a and 2b on the basis of the parking position stored in the parking position storage unit 6a when the vehicle is parked.
