Vehicle Blind-Zone Collision Avoidance During Turning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, especially commercial vehicles, face a high risk of collisions when turning due to blind zones, particularly with objects on the side or rear, which are not easily detected by drivers, especially when turning near curbs or intersections.
Innovation Solution
A method and apparatus that utilize sensors to predict the movement path of the vehicle and detect surrounding objects, determining collision risks and actuating braking and steering devices to avoid collisions, especially by using front and side detection sensors to gather information on road boundaries and other vehicles or pedestrians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driver manually operates the vehicle without assistance systems, then the device complexity is low, but the collision risk in blind zones increases
Solution Approach 1:
The system divides the detection task into multiple segments by using separate front detection sensors and side detection sensors. Each sensor targets specific blind zones (front blind zone and side blind zone), allowing comprehensive coverage while maintaining modular system architecture that balances complexity and effectiveness
Solution Approach 2:
The system performs preliminary detection of surrounding objects before the vehicle actually enters potential collision zones. By detecting objects in advance during the turning maneuver and predicting movement paths, the system prepares collision avoidance actions before critical moments arise, improving reliability without requiring overly complex real-time response systems
2Ease of operation
If the vehicle turns with a wide rotation radius, then the turning capability is improved, but the area covered by blind zones increases
Solution Approach 1:
The system extends detection from a single plane to multiple spatial dimensions by deploying sensors that detect objects in both front and side blind zones simultaneously. This multi-dimensional detection approach comprehensively monitors the expanded blind zone area created by wide rotation radius, allowing the vehicle to maintain good turning capability while compensating for increased blind zone coverage through enhanced spatial awareness
3Measurement precision
If sensors are used to detect surrounding objects, then the detection accuracy in blind zones is improved, but the energy consumption increases
Solution Approach 1:
The detection system is designed to serve multiple functions: detecting objects in front blind zones, detecting objects in side blind zones, and providing data for collision risk prediction. By making the sensor system multi-functional, the patent achieves high detection accuracy across all blind zones without requiring separate dedicated sensor systems for each function, thereby controlling energy consumption while maintaining precision

AI summary
A method for avoiding a collision of a vehicle, an apparatus for performing the method, and a computer program avoid a collision with an object positioned at a rear side or a side of an ego vehicle, which is a blind zone area when the ego vehicle turns, to prevent a side collision accident which may occur in a blind zone up turning driving, and determines a collision risk based on prestored surrounding object information upon restarting a vehicle to prevent the side collision accident due to carelessness of a driver upon driving after restarting of the vehicle.
