Solution Overview

Problem

Existing vehicle systems require manual driver intervention to broadcast decentralized environmental notification messages (DENM), which can divert attention from the road and compromise safety.

Innovation Solution

A vehicle system utilizing a primary deep learning model with a camera sensor to detect events and a secondary deep learning model on a server for validation, allowing auto-triggering of DENM messages without driver interaction, with periodic updates and confirmation through a telematic control unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual driver intervention is used to broadcast DENM messages, then the driver can control event notification, but driver attention is diverted from the road compromising safety

Engineering Contradiction:
Improvedriver control of event notificationVSAvoiddriving safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables automatic event detection and DENM message broadcasting through the deep learning model without requiring driver intervention. The electronic control unit autonomously processes images from the camera sensor, detects events, and triggers notifications, allowing the system to serve itself rather than relying on manual driver input.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical interaction (driver pressing buttons or touching screens) with an automated electronic system. The deep learning model and electronic control unit substitute for the driver's manual operations, automatically detecting events and broadcasting DENM messages based on image analysis.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automatic event detection is implemented using deep learning model, then driver distraction is reduced, but system complexity increases

Engineering Contradiction:
Improvedriving safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The deep learning model acts as an intermediary between the camera sensor and the DENM message broadcasting system. It processes images and determines whether events warrant notification, mediating between raw sensor data and the communication system while maintaining automated operation without direct driver involvement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the event detection process into distinct functional modules: image capture by camera sensor, event detection by deep learning model in the electronic control unit, and notification broadcasting by the telematic control unit. This segmentation allows each component to specialize in its function while working together autonomously.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If multiple sensor types are used for event detection, then detection accuracy improves, but system complexity and cost increase

Engineering Contradiction:
Improveevent detection accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex multi-sensor hardware systems with a simplified single-sensor approach enhanced by deep learning software. Instead of using multiple physical sensors (LIDAR, radar, cameras), the system uses only camera sensors but compensates for their limitations through advanced image processing and deep learning algorithms that can detect various event types with high accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameter of detection from physical sensor diversity to computational complexity. Rather than adding more sensor types, it enhances the processing capabilities of the existing camera sensor through deep learning models, transforming the approach from hardware complexity to software intelligence.

Inventive Principle:
Principle #35Parameter changes
