Vehicle Alert System Using Transient Condition Data for V2X Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication and sensing systems lack a warning or alert capability from the host vehicle to other receiving vehicles, limiting their effectiveness in preventing potential hazards.
Innovation Solution
A motor vehicle alert system that uses a communication module to receive and send vehicle data in a vehicle mobility data format, incorporating a tracker module to update vehicle data, a transient condition data device to identify hazardous conditions, and a message standard conformance module to transmit alerts to proximate vehicles, enabling the host vehicle to notify other vehicles of potential hazards through V2X telematics communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle communication and sensing systems are used to detect other vehicles and provide warnings to the driver, then collision avoidance capability is improved, but the system lacks a warning capability to other receiving vehicles
Solution Approach 1:
The system enables the host vehicle to serve multiple functions: detecting hazards, generating warnings, and communicating with both the driver and other vehicles. The communication module transmits transient condition data to multiple recipients (driver via warning device and other vehicles via V2V communication), making the system universally applicable for hazard notification across different targets.
Solution Approach 2:
The communication module acts as an intermediary that bridges the host vehicle and other receiving vehicles. It receives transient condition data from the tracker module, formats it according to message standards, and transmits it to other vehicles, enabling indirect communication and hazard warning without direct vehicle-to-vehicle contact.
2Reliability
If the system transmits transient condition data to other vehicles, then collision avoidance is improved, but the device complexity increases
Solution Approach 1:
The system divides the alert generation process into separate functional modules: the tracker module for vehicle data collection, the transient condition data device for hazard detection, the message standard conformance module for data formatting, and the communication module for transmission. This segmentation allows each module to perform its specific function independently, reducing overall system complexity while maintaining effectiveness.
Solution Approach 2:
The system changes the state of vehicle data from raw sensor inputs to formatted alert messages by transforming the data structure and content. The message standard conformance module converts internal vehicle data formats into standardized communication formats, enabling efficient transmission without requiring complex interface management.
3Reliability
If the system continuously monitors and transmits vehicle data, then safety coverage is improved, but the information processing load increases
Solution Approach 1:
The system extracts only the critical transient condition information from the continuous stream of vehicle data. Instead of transmitting all sensor data continuously, the transient condition data device identifies and extracts only the hazardous conditions (such as swerve conditions) that require alerting, reducing the information processing load while maintaining safety coverage.
Solution Approach 2:
The tracker module continuously updates vehicle data in advance, and the transient condition data device pre-evaluates this data to identify potential hazards before they manifest as actual collisions. This preliminary monitoring and evaluation allows the system to prepare alert messages in advance, reducing real-time processing requirements during actual hazard events.

AI summary
A motor vehicle alert system based on vehicle dynamics input includes a communication module positioned in a host vehicle receiving and sending vehicle data in a vehicle mobility data format. A list generator in communication with the communication module generates the vehicle data as specific vehicle identification data in a track list to distinguish a sensed vehicle and at least one other vehicle positioned proximate the host vehicle. A tracker module in communication with the list generator periodically updates the vehicle data for the sensed vehicle and the at least one other vehicle. A transient condition data device generates data identifying when a transient condition of the sensed vehicle is present. A message standard conformance module receives the data identifying the transient condition and forwards the data identifying the transient condition to the communication module for transmission to the at least one other vehicle proximate to the host vehicle.
