Vehicle Control Unit for Loss of Control Warning via WAVE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle communication technologies primarily focus on propagating operating status information but fail to effectively prevent traffic accidents by not estimating and warning of potential risk scenarios, such as loss of control, which can lead to collisions.
Innovation Solution
An apparatus and method that utilize WAVE messages to broadcast and receive status information about vehicle control systems like ABS, ESC, and TCS, estimating potential accident risks and warning drivers through audible, visible, and vibrating means, or providing behavior guides like braking or emergency lighting to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle-to-vehicle communication systems broadcast operating status information, then information exchange between vehicles is improved, but the ability to prevent traffic accidents through risk estimation and warning is insufficient
Solution Approach 1:
The system performs preliminary risk estimation by analyzing vehicle status information before accidents occur. The control unit continuously monitors broadcast WAVE messages and estimates potential collision risks in advance, enabling early warning to drivers rather than reacting after accidents happen.
Solution Approach 2:
The patent introduces a control unit as an intermediary that processes vehicle status information from WAVE messages. This intermediary analyzes the data, estimates risks, and generates warnings, bridging the gap between raw information exchange and actionable accident prevention.
2Reliability
If the system monitors and analyzes WAVE messages from surrounding vehicles, then accident risk detection is improved, but the complexity of the control system increases
Solution Approach 1:
The control unit performs multiple functions: receiving WAVE messages, analyzing vehicle status information, estimating collision risks, and generating warnings. By consolidating these diverse functions into a single multi-functional control unit, the system achieves high reliability without proportionally increasing overall system complexity.
3Reliability
If the system provides early warning and behavior guides to drivers, then traffic accident prevention is improved, but the complexity of warning and guidance systems increases
Solution Approach 1:
The warning system is segmented into distinct output channels: audible warnings, visible warnings, and behavior guides. This segmentation allows each component to be optimized independently and provides drivers with multiple types of information in a structured manner, improving effectiveness while managing complexity through modular design.

AI summary
An apparatus for warning loss of control of a vehicle using communications between vehicles may include: a speed detecting unit for detecting a speed of a vehicle; a position detecting unit for detecting a current position and a travel direction of the vehicle; a route estimating unit for estimating a future position of the vehicle after a time period using the current speed and the position information; a WAVE message generating unit for generating a WAVE message comprising the future position information of the vehicle; a WAVE data communicating unit for broadcasting the WAVE message to a surrounding vehicle and an infrastructure periodically, and receiving WAVE message broadcast from the surrounding vehicle and the infrastructure; and a control unit for sensing accident risk using the future position information of the vehicle and the future position information of the surrounding vehicle, when the surrounding vehicle is in loss of control.
