Solution Overview
Problem
Current vehicle-to-everything (V2X) communication systems lack efficient methods for initiating communication between vehicles based on the selection of target objects, leading to limitations in real-time data sharing and audio experiences between moving vehicles.
Innovation Solution
A system and method that allow a first device to detect the selection of a target object external to the device and initiate a communication channel using V2X or C-V2X communication systems, enabling the reception and spatialization of audio signals based on the relative position of the target object.

1Reliability
If V2X communication systems are used for real-time audio transmission between vehicles, then the audio experience and safety are improved, but the system complexity and latency requirements become more challenging to meet
Solution Approach 1:
The communication system is segmented into distinct functional modules: audio packet reception module, decoding module, spatialization module, and rendering module. Each module handles a specific aspect of audio processing, reducing overall system complexity while maintaining real-time performance through specialized processing pipelines.
Solution Approach 2:
The system performs preliminary actions by pre-establishing communication channels between vehicles before audio transmission begins. Spatialization parameters are pre-calculated based on vehicle relative positions, and audio packets are buffered and prepared for decoding in advance, reducing latency during actual audio playback.
2Ease of operation
If spatialized audio output is generated based on vehicle relative position, then the user experience and situational awareness are improved, but the processing time and computational requirements increase
Solution Approach 1:
The audio spatialization system dynamically adjusts rendering parameters based on real-time vehicle relative positions. As vehicles move, the system continuously updates spatialization calculations to maintain accurate audio source positioning, providing enhanced user experience without excessive processing delays through efficient dynamic recalibration.
Solution Approach 2:
The system replaces complex real-time 3D audio processing with optimized algorithms that calculate spatialized output based on simplified positional parameters. By substituting full physics-based acoustic modeling with computationally efficient spatialization techniques, the system reduces processing time while maintaining perceptual audio quality.
3Productivity
If audio packets are received and decoded in real-time from selected target vehicles, then the communication efficiency is improved, but the data transmission requirements and network load increase
Solution Approach 1:
The system extracts only the essential audio data packets from transmitted communications, filtering out redundant information. By taking out only the necessary audio packets for decoding and spatialization, the system maintains high communication efficiency while reducing the overall data transmission volume through selective packet processing.
