Idle Vehicle V2X Communication via Relay Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Vehicle-to-Everything (V2X) communication standards do not effectively manage energy conservation for vehicles at rest or idle, as they primarily focus on vehicles in motion, leading to challenges in transmitting safety-related information with limited energy resources.
Innovation Solution
Implementing advanced energy conservation schemas in V2X communication systems that allow idle vehicles to transmit messages using the lowest energy methods available, such as relaying through nearby vehicles or infrastructure, by analyzing sensor data to prioritize and optimize message transmission based on battery availability and urgency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If idle vehicles transmit V2X messages using conventional high-power methods, then message transmission reliability is improved, but energy consumption increases beyond available battery resources
Solution Approach 1:
The patent introduces relay nodes (other vehicles or infrastructure) as intermediaries to forward messages from idle vehicles. This allows the idle vehicle to transmit messages with minimal energy by relying on relay nodes to propagate the information further, resolving the contradiction between transmission reliability and energy consumption.
Solution Approach 2:
The system dynamically adjusts transmission parameters based on vehicle state and energy availability. When a vehicle is idle and energy-constrained, the system switches to low-power transmission modes and utilizes relay nodes, while transitioning to higher-power direct transmission when the vehicle is in motion and energy is abundant.
2Adaptability or versatility
If V2X communication focuses on vehicles in motion, then existing standards and protocols are optimized, but idle vehicles cannot effectively transmit safety information
Solution Approach 1:
The patent extends V2X communication functionality to work universally across both moving and idle vehicle states. By incorporating state-aware communication protocols and relay node mechanisms, the system enables idle vehicles to participate in V2X communications equally, ensuring safety information can be transmitted regardless of vehicle motion status.
3Reliability
If idle vehicles continuously monitor and transmit sensor data, then safety and autonomy are improved, but battery energy depletes faster
Solution Approach 1:
The system implements periodic sensing and selective transmission rather than continuous operation. Sensors monitor the environment continuously but data transmission occurs only at periodic intervals when events are detected or at scheduled times, significantly reducing energy consumption while maintaining safety monitoring capabilities.
Solution Approach 2:
The communication system incorporates feedback mechanisms where relay nodes acknowledge receipt of messages and provide status information back to the idle vehicle. This allows the vehicle to optimize its transmission timing and frequency based on actual communication needs and energy levels, extending battery life while maintaining effective safety monitoring.

AI summary
This disclosure describe techniques to transmitting information from a vehicle to an intended destination, via a selected transmission method. A system is described that can capture current sensor data from a vehicle system of an idle vehicle and infer the occurrence of a trigger event. In doing so, the system may generate a message indicating the occurrence of the trigger event and transmit the message to one or more connected devices in a range of the intended destination.
