Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle collision avoidance systems are inadequate in complex driving situations such as overtaking or approaching intersections, particularly roundabouts, and do not effectively account for vehicles that may cross paths, leading to potential collisions and reduced safety and comfort.

Innovation Solution

A signaling system implemented in vehicles that determines the presence of crossing vehicles, suggests a behavior adjustment, and communicates this suggestion through electromagnetic signals or network messages, allowing both vehicles to adapt their driving accordingly, with priority determination and driver notification options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing vehicle collision avoidance systems are used, then basic collision detection is provided, but the systems are insufficient in complex driving situations such as overtaking or approaching intersections

Engineering Contradiction:

Improvecollision avoidance reliabilityVSAvoidadaptability to complex driving situations

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system segments the detection space into multiple zones (front, rear, left, right) and applies different detection algorithms and priority levels to each zone. This allows the system to handle complex driving situations by dividing the problem into manageable segments with specific detection rules for each area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from traditional two-dimensional sensor detection to three-dimensional spatial awareness by incorporating elevation data and creating a volumetric understanding of the environment. This enables better detection of vehicles in complex situations like overtaking or approaching intersections from multiple angles.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Difficulty of detecting and measuring

If traditional detection methods are used, then simple presence detection is achieved, but vehicles that may cross paths are not effectively accounted for

Engineering Contradiction:

Improvedetection simplicityVSAvoidcrossing vehicle detection accuracy

Core Design Contradiction:

Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The system performs preliminary detection and classification of vehicles before they become immediate threats. By identifying potential crossing vehicles early and predicting their trajectories, the system prepares advance warnings and suggests preventive behaviors, improving detection accuracy without adding complex real-time processing during critical moments.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback loops where detection results inform prediction models, which in turn refine detection parameters. This closed-loop approach allows the system to learn from past detections and improve its ability to identify crossing vehicles, balancing detection simplicity with improved accuracy over time.

Inventive Principle:

Principle #23Feedback

3Device complexity

If no intervehicle communication is implemented, then system complexity is reduced, but safety and comfort in complex traffic scenarios are reduced

Engineering Contradiction:

Improvesystem complexityVSAvoidsafety and comfort

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system uses electromagnetic signals as an intermediary to communicate between vehicles and with infrastructure. This mediator enables information exchange about detected vehicles, suggested behaviors, and traffic conditions without requiring direct physical connection or highly complex peer-to-peer communication protocols, thus balancing complexity with improved safety.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If proactive behavior adjustment is enabled, then collision risk is reduced, but driver vigilance and manual control may be reduced

Engineering Contradiction:

Improvecollision risk reductionVSAvoiddriver vigilance and control

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements partial automation where it suggests behaviors and provides warnings but leaves final decision-making to the driver. By offering selective assistance rather than full automation, the system reduces collision risk through proactive suggestions while maintaining driver vigilance and ultimate control, avoiding the complacency that can result from excessive automation.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The invention relates to a method for signaling a suggestion of a behavior, implemented by a signaling system, characterized in that it comprises the following steps: • determining (S500) an arrival of a first vehicle at a portion of a traffic route, there being a possibility of a second vehicle crossing paths with the first vehicle at said portion; • determining (S510) an arrival of the second vehicle at said portion; • determining (S520) a suggestion of a behavior of the second vehicle at said portion; and • sending (S530) a signal of said suggestion to the second vehicle; and • receiving (S640) a notification that said signal has been taken into account by the second vehicle.
