Driver Assistance Apparatus Using Inter-Vehicle Communication for Hazard Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems fail to accurately predict potential dangers from other vehicles and automatically control vehicle operations such as steering, speed reduction, or acceleration in response to dangerous driving patterns, especially when the dangerous vehicle is hidden from view or driving abnormally.
Innovation Solution
A driver assistance apparatus that includes a sensing unit to acquire information about nearby vehicles and a processor to detect the driver's gaze and pupil size, assess the driver's state, and control vehicle operations based on the driving pattern of potentially dangerous vehicles, using inter-vehicular communication to share information and adjust the vehicle's state accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver assistance system monitors only visible vehicles, then the system complexity is reduced, but the safety is compromised because hidden dangerous vehicles cannot be detected
Solution Approach 1:
The patent introduces communication units as intermediaries that enable vehicles to exchange information about dangerous driving patterns. This allows the system to detect hidden dangerous vehicles through information from other vehicles or infrastructure, improving safety without requiring direct visual detection, thus resolving the contradiction between safety and system complexity
Solution Approach 2:
The system performs preliminary detection of dangerous driving patterns by monitoring acceleration, braking, and steering behaviors before a collision occurs. By identifying potential dangers in advance through communication networks, the system can alert drivers or automatically respond, improving safety without needing complex real-time visual tracking of all surrounding vehicles
2Speed
If the system automatically controls vehicle operations, then the response time to dangerous situations is reduced, but the driver's control and decision-making ability may be compromised
Solution Approach 1:
The system implements partial automation by providing assistance rather than full automatic control. It can issue warnings, suggest maneuvers, or partially control specific functions like braking or steering assistance, allowing the driver to maintain ultimate control while benefiting from faster automated responses to dangerous situations
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor driver intent and vehicle state, adjusting automated controls in real-time. This allows the system to respond quickly to dangers while respecting driver decisions, resolving the contradiction between fast automated response and driver control by creating a collaborative control loop

AI summary
Disclosed are driver assistance apparatus and a control method for the same. The driver assistance apparatus includes a sensing unit configured to acquire information regarding an object outside a vehicle, the object including a first other vehicle being driven in the vicinity of the vehicle, and a processor configured to judge whether the first other vehicle is a dangerous vehicle based on at least one of the information regarding the object, user input provided from a driver of the vehicle, information regarding the state of the driver, and information regarding the first other vehicle provided from a second other vehicle being driven in the vicinity of the vehicle, and to execute at least one predetermined operation upon judging that the first other vehicle is a dangerous vehicle.
