Vehicle Intersection Warning System Brake Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle collision warning systems are inadequate in effectively evaluating scenarios at intersections and providing timely warnings to prevent collisions between host and remote vehicles.
Innovation Solution
A vehicle intersection warning method that exchanges information between host and remote vehicles, determines the presence of an intersection, assesses the possibility of contact, and evaluates the operating condition of the host vehicle's brake to determine the appropriate warning type to provide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle collision warning systems are implemented, then safety is improved, but the system fails to effectively evaluate intersection scenarios and provide timely warnings
Solution Approach 1:
The system performs preliminary evaluation of intersection scenarios by determining the presence of intersections and assessing collision possibilities before actual collisions occur. The processor evaluates multiple parameters including vehicle positions, velocities, and intersection geometries in advance to generate timely warnings.
Solution Approach 2:
The warning system is divided into distinct functional modules: intersection detection module, collision possibility assessment module, brake condition evaluation module, and warning generation module. Each module processes specific aspects of the scenario independently and contributes to the overall warning decision.
2Measurement precision
If comprehensive vehicle information exchange is performed, then assessment accuracy is improved, but system complexity increases
Solution Approach 1:
The system uses a universal communication protocol that allows vehicles to exchange multiple types of information (position, velocity, acceleration, brake status) through a single standardized interface. This multi-functional approach reduces the need for separate dedicated systems for each parameter.
Solution Approach 2:
A centralized processor acts as an intermediary that receives information from multiple vehicles, processes the data, and generates warning decisions. This mediator approach simplifies the overall system architecture by centralizing the complex evaluation logic in one location rather than distributing it across multiple vehicles.
3Reliability
If brake operating condition evaluation is added, then warning relevance is improved, but processing time increases
Solution Approach 1:
The system continuously monitors and evaluates brake operating conditions in advance as part of the regular information exchange cycle. By maintaining up-to-date knowledge of brake status beforehand, the system can quickly determine warning relevance without adding significant processing delay when a potential collision scenario is detected.

AI summary
A vehicle intersection warning method is provided. The method comprises exchanging host vehicle information and remote vehicle information between a host vehicle and a remote vehicle, determining a presence of a road intersection based on at least one of the host vehicle information and the remote vehicle information. determining, by operation of a processor, whether a possibility of contact between the host vehicle and the remote vehicle exists proximate the intersection based on the exchanged host vehicle information and remote vehicle information, and evaluating an operating condition of a brake of the host vehicle while the possibility of contact exists to determine a type of warning to provide to the host vehicle.
