Vehicle Collision Avoidance Steering Control with Corner Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision avoidance systems for vehicles risk causing the vehicle to veer into an opposing lane when changing direction to avoid an object ahead, especially in scenarios involving corners or hills, leading to potential collisions.
Innovation Solution
A collision avoidance apparatus that includes detection means, collision avoidance means, corner determination means, and prohibition means to assess whether a corner or hill is present and adjust the vehicle's steering control accordingly, preventing direction changes that could lead to lane deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steering control is used to change the travelling direction of the own vehicle to avoid collision with an object ahead, then collision avoidance capability is improved, but the risk of veering into an opposing lane increases
Solution Approach 1:
The system performs preliminary detection of corners and hills ahead using map data or recognition devices before executing steering avoidance maneuvers. By identifying these road features in advance, the system can determine whether steering control is safe to execute, thereby preventing the harmful effect of veering into opposing lanes while maintaining collision avoidance capability when conditions permit
Solution Approach 2:
The system continuously monitors road conditions by detecting corners and hills ahead, and uses this feedback information to dynamically adjust whether steering avoidance is permitted. This closed-loop control ensures that steering maneuvers are only executed when road geometry allows safe execution, resolving the contradiction between collision avoidance and lane deviation prevention
2Reliability
If the travelling direction of the own vehicle is changed to avoid collision with an object ahead, then collision avoidance is achieved, but lane discipline is compromised
Solution Approach 1:
The system determines in advance whether the road geometry (corners, hills) permits safe steering maneuvers before allowing collision avoidance steering. This preliminary assessment ensures that lane position stability is maintained while still enabling collision avoidance when road conditions are favorable
Solution Approach 2:
The system changes the operational parameter of steering control availability based on detected road conditions. When corners or hills are detected, steering avoidance is prohibited; when such features are absent, steering avoidance is permitted. This dynamic parameter adjustment resolves the contradiction between maintaining lane discipline and achieving collision avoidance

AI summary
A collision avoidance apparatus includes a control unit that is configured to perform a collision avoidance process. The control unit determines whether or not an object is present ahead of the own vehicle. When the control unit determines that an object ahead is present, the control unit determines whether or not there is a likelihood of a collision between the object ahead and the own vehicle and whether or not a corner is present ahead of the own vehicle. When the control unit determines that a corner is not present and when a predetermined collision avoidance condition is established, the control unit is capable of changing a travelling direction of the own vehicle to avoid collision between the object ahead and the own vehicle. When the control unit determines that a corner is present, the control unit does not perform a travelling direction change of the own vehicle.
