Vehicle Brake Control for Collision Notification and Hit-and-Run Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic braking systems do not effectively prevent accident expansion or deter drivers from fleeing the scene after a collision, as they lack integrated notification and brake control mechanisms to ensure the vehicle remains stationary during and after the incident.
Innovation Solution
A device and method that includes a collision detecting unit, notification unit, and brake control unit to automatically actuate the brake and maintain its state during notification to external organizations, preventing vehicle movement and potential driver flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver communicates with an external organization after a collision, then notification is provided, but the vehicle may start to move and the accident may expand
Solution Approach 1:
The brake control unit maintains the actuated state of the brake in advance during the notification process. This preliminary action ensures the vehicle remains stationary before any potential movement can occur, thereby preventing accident expansion while allowing notification to proceed
Solution Approach 2:
The brake control unit acts as an intermediary between the notification unit and the vehicle's motion. By maintaining brake actuation during notification, it mediates between the need to communicate accident information and the need to prevent vehicle movement that could worsen the situation
2Ease of operation
If the driver feels uncomfortable or upset after collision, then the driver may fail to actuate the parking brake, but the vehicle may move and become involved with injured persons
Solution Approach 1:
The system performs self-service by automatically maintaining brake actuation through the brake control unit without requiring driver intervention. This eliminates the need for the driver to manually operate the parking brake, even when uncomfortable or upset, thereby preventing unintended vehicle movement
Solution Approach 2:
The brake control unit provides continuous feedback control by monitoring the notification state and maintaining brake actuation accordingly. This automated feedback loop ensures the vehicle remains stationary throughout the notification process, compensating for any driver inability or unwillingness to operate the brake
3Device complexity
If no brake control is carried out after collision, then the system is simple, but ill-intentioned drivers may flee from the accident scene
Solution Approach 1:
The brake control unit maintains brake actuation in advance during the notification process, creating a preliminary constraint that prevents vehicle movement. This deterrent effect makes it difficult for ill-intentioned drivers to flee the scene, thereby enhancing driver accountability without requiring complex additional systems

AI summary
When a collision between a vehicle and a physical object is detected, a notification control unit transmits a notification command to a notification device. Upon receiving the notification command, the notification device notifies an external emergency notification center. While the notification device is notifying the emergency notification center, a brake control unit maintains the actuated state of a brake device and stops the vehicle. This configuration makes it possible to prevent any increase in accidents after a vehicle collision, and to prevent the driver from escaping.
