Emergency Stop Control Using Rear Vehicle Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control technologies fail to prevent collisions by not considering the visibility state of rear vehicles when an emergency stop is initiated, leading to potential accidents due to obscured views caused by preceding vehicles.
Innovation Solution
An apparatus and method that utilize vehicle sensors and rear sensors to detect the relative distance and speed of rear vehicles, adjusting the vehicle's speed based on collision risk, and determining the visibility state by considering the heights and widths of both the target and preceding vehicles, to prevent collisions during emergency stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle performs automatic emergency stopping without considering rear vehicle visibility, then the driver's safety is improved, but the risk of collision with rear vehicles increases
Solution Approach 1:
The system performs preliminary detection of rear vehicles and their visibility states before executing emergency stopping. By identifying whether rear vehicles can observe the stopping vehicle through the first rear vehicle's obstruction, the system prepares appropriate deceleration strategies in advance to prevent collisions
Solution Approach 2:
The system continuously monitors the positions and states of first and second rear vehicles, using this feedback information to dynamically adjust the stopping deceleration. When the second rear vehicle's visibility is obstructed, the system reduces deceleration to allow the stopping vehicle to remain visible as a warning to approaching traffic
2Speed
If the vehicle stops quickly in emergency, then the stopping distance is reduced, but the visibility warning to rear vehicles is insufficient
Solution Approach 1:
The system dynamically adjusts the deceleration rate based on real-time visibility conditions. When the second rear vehicle's field of view is obstructed by the first rear vehicle, the system reduces deceleration to maintain the stopping vehicle's visibility as a warning signal. When visibility is not obstructed, the system can apply stronger deceleration

AI summary
Disclosed are an apparatus for controlling a stop of a vehicle and a method thereof. In order to prevent a collision accident occurring by a second rear vehicle in an emergency stop of the vehicle in advance, the apparatus includes a vehicle sensor that detects various types of information on a target vehicle, a rear sensor that detects a first rear vehicle and a second rear vehicle driving behind the target vehicle, and a controller that is electrically connected to the vehicle sensor and the rear sensor to control an emergency stop of the target vehicle in consideration of a state of a field of view of the second rear vehicle with respect to the target vehicle when the target vehicle is stopped in emergency.
