Inter-Vehicle Management Apparatus Dynamic Risk Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inter-vehicle management technologies rely solely on visibility state and do not adequately address the dynamic changes in safe distance due to driving scene and behavior, leading to insufficient safety and comfort assurance.
Innovation Solution
An inter-vehicle management apparatus and method that includes a processor to acquire scene information, estimate driving scenes, determine driving risk based on both scene and behavior information, and present assist information to the user through an information presentation unit before the emergency control unit activates, ensuring the user addresses the risk proactively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the target distance for inter-vehicle distance is changed based only on visibility state, then the control system is simple, but the safety and comfort of the user are not adequately assured because safe distance changes dynamically with driving scene and behavior
Solution Approach 1:
The patent implements dynamic adjustment of target inter-vehicle distance based on real-time detection of driving scenes (e.g., curved road, intersection, straight road) and user behavior patterns. The system transitions from static visibility-based control to dynamic scene-and-behavior-based control, allowing the target distance to adapt continuously to changing driving conditions and user responses, thereby improving safety assurance while maintaining reasonable system complexity through modular detection and processing components
Solution Approach 2:
The system incorporates feedback mechanisms by monitoring user responses to presented information and adjusting subsequent information presentation and target distance settings accordingly. The risk determination section uses feedback from scene estimation and behavior detection to continuously update risk levels, which then feed back into information presentation control and emergency control unit activation thresholds, creating a closed-loop control system that improves safety through adaptive response to user behavior
2Ease of operation
If the emergency control unit operates only when inter-vehicle distance reaches minimum target distance, then the activation condition is clear, but the safety and comfort of the user are not adequately assured because proactive risk addressing is missing
Solution Approach 1:
The patent implements preliminary action by presenting assist information to the user before the emergency control unit is activated. The system detects driving scenes and behavior patterns, determines risk levels in advance, and presents appropriate information (visual, auditory, or haptic) to prompt users to address potential risks before critical conditions are reached. This proactive information presentation allows users to take corrective actions before emergency braking or other emergency controls are triggered, enhancing safety while maintaining clear activation conditions
Solution Approach 2:
The information presentation unit serves as an intermediary between the risk determination system and the emergency control unit. Instead of direct transition from risk detection to emergency control activation, the system introduces an intermediate information presentation stage that communicates risk levels to the user and prompts appropriate responses. This intermediary mechanism bridges the gap between clear activation conditions and proactive safety assurance by enabling gradual user intervention before emergency controls engage

AI summary
An inter-vehicle management apparatus acquires scene information about a driving scene of a host vehicle, estimates the driving scene based on the scene information acquired, acquires behavior information about a driving behavior of the host vehicle driven by the user, determines a driving risk of the host vehicle driven by the user, based on the driving scene estimated and on the behavior information acquired, and controls a presentation of assist information by an information presentation unit in order to prompt the user to address the driving risk. When the driving scene estimated represents a follow-up traveling state of the host vehicle following the preceding vehicle, the assist information to be presented by the information presentation unit is selected based on a magnitude of the driving risk determined before the operation by an emergency control unit.
