Vehicle Wireless Apparatus Location-Based Transmission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-to-vehicle and infrastructure-to-vehicle communication systems face challenges in adhering to varying radio frequency regulations across countries, leading to potential violations when vehicles with terminal devices are exported or imported, as the systems automatically transmit signals upon startup without determining compliance with local radio laws.
Innovation Solution
A wireless apparatus is developed for vehicles, equipped with a detector to identify vehicle startup, an acquirer to gather position information, and a controller to determine if the vehicle is within a designated region, activating or deactivating the transmission function to ensure compliance with local radio laws by determining whether to transmit signals based on the vehicle's location.

Engineering Contradiction Analysis
1Productivity
If the terminal device transmits a signal automatically upon vehicle startup, then the communication function is activated and ready for use, but the transmission may violate the Radio Law of the destination or importing country
Solution Approach 1:
The controller determines whether signal transmission is permitted before the terminal device actually transmits signals. The detector detects vehicle startup, the acquirer obtains position information, and the controller examines whether the position is within a designated region before activating transmission, preventing legal violations in advance
Solution Approach 2:
The controller acts as an intermediary between the vehicle startup event and the signal transmission function. It intermediates by detecting startup, acquiring position information, examining whether transmission is permitted, and only then activating the transmission function if compliant with local radio laws
2Productivity
If the transmission function is always activated, then communication availability is maximized, but radio wave transmission may occur in areas where it is restricted or prohibited
Solution Approach 1:
The transmission function's activation state is made dynamic rather than static. The controller continuously monitors position information and dynamically adjusts the transmission function's activation state based on whether the vehicle is within designated regions, allowing transmission when permitted and preventing it when restricted
Solution Approach 2:
The system implements feedback by continuously acquiring position information and examining whether transmission is permitted at different locations. The controller receives feedback from position monitoring and adjusts transmission activation accordingly, ensuring communication availability only in legally permitted areas

AI summary
A vehicle control method for a first vehicle is provided. The first vehicle includes a global navigation satellite system (GNSS) receiver configured to acquire a position of the first vehicle and a wireless communicator configured to transmit at least the position of the first vehicle to a second vehicle. The method acquires the position of the first vehicle by the GNSS receiver when an engine or a motor of the first vehicle starts. The acquired position of the first vehicle is transmitted to the second vehicle by the wireless communicator when the acquired position of the first vehicle is within a region, and not transmitted to the second vehicle when the acquired position is out of the region.
