Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles equipped with blind spot detection (BSD) systems have fixed sensing areas, failing to adapt to varying driving situations and unable to effectively communicate risk levels to drivers.
Innovation Solution
A driver assistance apparatus that dynamically adjusts the BSD zone based on vehicle information and environmental factors, outputting alarm signals of different levels to enhance driver awareness of potential risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed BSD zone is used for detecting other vehicles, then the detection area is clearly defined, but the system cannot adapt to varying driving situations and risk levels
Solution Approach 1:
The BSD zone is changed from a fixed static area to a dynamic adjustable area that varies based on driving situations. The processor adjusts the BSD zone boundaries according to vehicle speed, acceleration, and other driving parameters, allowing the detection area to expand or contract dynamically to match the current risk level and driving context.
Solution Approach 2:
The system changes the parameters defining the BSD zone (such as zone boundaries, detection sensitivity, and alarm thresholds) based on varying driving conditions. By modifying these parameters in real-time according to vehicle state and environmental factors, the system adapts its detection behavior without requiring a completely different detection mechanism.
2Reliability
If alarm signals are output for all detected objects in the BSD zone, then comprehensive safety monitoring is achieved, but unnecessary alarms increase and reduce driver trust
Solution Approach 1:
Different alarm levels and notification methods are applied to different regions within the BSD zone. Instead of treating all detected objects uniformly, the system evaluates the position, speed, and characteristics of each object relative to the vehicle and generates appropriately weighted alarm signals. Critical objects in high-risk zones trigger immediate alerts, while less concerning objects generate softer notifications or are monitored without alarming the driver.
3Area of stationary object
If the BSD zone covers a large area to detect all potential risks, then comprehensive coverage is achieved, but the system cannot distinguish between high and low risk situations
Solution Approach 1:
The BSD zone is divided into multiple sub-zones or risk levels, each representing different degrees of danger. The processor segments the detection area into regions such as high-risk zones (close to vehicle, direct collision path), medium-risk zones (moderate distance, potential conflict), and low-risk zones (peripheral areas). This segmentation allows the system to maintain comprehensive coverage while providing differentiated risk assessment for objects in different regions.

AI summary
The present invention relates to a driver assistance apparatus for a vehicle, which includes a sensing unit for sensing an object located outside the vehicle, and a processor for changing a blind spot detection (BSD) zone on the basis of vehicle information and providing a signal corresponding to an alarm on the basis of the changed BSD zone, thereby varying the BSD zone for sensing other vehicles according to situation and outputting an alarm indicating a level of danger.
