Rear Side Warning Sensing for Blind-Spot Tracking in Lane Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear lateral warning systems for vehicles fail to detect vehicles entering from the rear when the host vehicle changes lanes, leading to increased accident risks due to blind spots not being adequately monitored by radar sensors.
Innovation Solution
A system and method that adjust the monitoring area of a rear sensing device based on the vehicle's turning angle, using a driving determination device to assess lane changes and reset monitoring points and lines to maintain detection of rear vehicles, thereby preventing collisions and ensuring driving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar sensor monitors the rear lateral side of the vehicle with a fixed monitoring area, then the system can detect vehicles in the blind spot when the vehicle drives straight, but the monitoring range does not include the rear lateral vehicle when the vehicle changes lanes
Solution Approach 1:
The monitoring area is made dynamic by adjusting its position and orientation based on the vehicle's turning angle. The controller receives turning angle information from the driving determination device and dynamically repositions the monitoring area to track the rear lateral vehicle during lane changes, resolving the contradiction between fixed monitoring reliability and adaptability to lane changes.
Solution Approach 2:
The system changes the parameters of the monitoring area (position, orientation, and boundaries) based on the vehicle's turning angle. When the vehicle changes lanes, the monitoring area parameters are adjusted to follow the vehicle's new trajectory, ensuring continuous detection capability while adapting to the changing driving conditions.
2Reliability
If the monitoring area is adjusted dynamically based on turning angle, then the system can maintain detection of rear lateral vehicles during lane changes, but the system complexity increases due to additional control logic
Solution Approach 1:
The driving determination device serves multiple functions: it determines driving direction, calculates turning angles, and provides this information to the controller for monitoring area adjustment. By making this device multi-functional, the system achieves dynamic monitoring adaptation without adding separate dedicated components, thus managing complexity while improving reliability.
Solution Approach 2:
The controller acts as an intermediary that receives turning angle information from the driving determination device and translates it into monitoring area adjustments. This intermediary role allows the system to manage the complexity of dynamic adjustment through a centralized control logic rather than distributed complex mechanisms.

AI summary
The present disclosure discloses a system and a method of rear lateral sensing of a vehicle for resetting a monitoring area on the rear lateral side of the vehicle according to a turning angle of the vehicle when the vehicle changes lanes so that a blind spot generated at the time of a lane change is removed, thereby preventing a collision with a vehicle located on the rear lateral side of the vehicle and securing driving stability.
