Driving Assistance Apparatus Proactive Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems cannot ensure the safety of a subject vehicle when a dangerously running vehicle, such as one with a drowsy driver, is approaching, as they rely on driver notification and evaluation rather than proactive collision avoidance.
Innovation Solution
A driving assistance apparatus equipped with processing circuitry and a communicator that identifies the driving state of a following vehicle through image recognition, determines surrounding circumstances, and controls autonomous driving to avoid collisions by communicating with the following vehicle and adjusting the subject vehicle's path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver assistance apparatus notifies the driver of the subject vehicle about the driving performance of the following vehicle, then the driver can be aware of potential dangers, but the driver cannot necessarily handle the situation calmly when a dangerously running vehicle is approaching
Solution Approach 1:
The system performs preliminary identification of dangerous driving states through pattern matching of face orientation and eye status, and executes preliminary notification to the following vehicle before a collision situation develops, allowing preventive action rather than reactive response
Solution Approach 2:
The communication device serves as an intermediary by transmitting notifications about dangerous driving states to the following vehicle, enabling the subject vehicle to indirectly influence the behavior of the dangerously running vehicle without requiring direct driver intervention
2Loss of information
If the system monitors the following vehicle and notifies the driver through a display speaker, then the driver receives information about driving performance, but the driver assistance apparatus cannot secure the safety of the subject vehicle with certainty in dangerous situations
Solution Approach 1:
The system establishes a feedback loop by notifying the following vehicle of its dangerous driving state, which may prompt the driver to correct their behavior, thereby creating a self-correcting system that continuously monitors and responds to safety conditions
Solution Approach 2:
The system executes preliminary identification and notification processes before a collision becomes inevitable, allowing the following vehicle driver time to respond and correct their driving behavior, thus preventing the dangerous situation from escalating
3Measurement precision
If the system uses pattern matching to recognize face orientation and eye status, then the driving state can be identified, but the system requires additional processing complexity to analyze images around the subject vehicle
Solution Approach 1:
The system applies pattern matching specifically to critical local features such as face orientation and eye status rather than analyzing the entire image, focusing computational resources on the most indicative indicators of driver state
Data Source
AI summary
A driving assistance apparatus includes processing circuit, and a communicator that communicates with the outside. The processing circuitry executes the following processes: identifying a driving state of a driver in a following vehicle behind a subject vehicle on the basis of a rear image containing the back of the subject vehicle; determining circumstances around the subject vehicle on the basis of images around the subject vehicle including the rear image; and controlling the autonomous driving of the subject vehicle on the basis of the driving state of the driver in the following vehicle, identified in the identifying process, and the circumstances, determined in the determining process.
