Vehicle Collision Avoidance Support with Steering Angle Intervention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision avoidance support systems for vehicles often provide unnecessary driving support when the steering angle is greater than a predetermined angle, leading to either suppressed necessary support or unnecessary activation, causing discomfort and potential collisions.
Innovation Solution
A collision avoidance support device and method that includes a support control unit, a suppression unit, and an intervention limiting unit to determine the necessity of support suppression based on vehicle information and the running environment, limiting intervention when the steering angle is greater than a predetermined angle, and adjusting support accordingly.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the driving support is suppressed when the steering angle is equal to or greater than a predetermined angle, then unnecessary driving support is reduced, but necessary driving support may be suppressed in situations where it is actually needed
Solution Approach 1:
The patent applies local quality by differentiating the suppression logic based on specific driving conditions. Instead of uniformly suppressing driving support when steering angle exceeds the threshold, the system selectively suppresses support only in specific scenarios (e.g., when shift device is in non-driving range or within a predetermined time after shift) while maintaining support in other scenarios. This localized application of suppression resolves the contradiction by ensuring necessary support is not suppressed.
Solution Approach 2:
The patent implements dynamics by making the suppression decision adaptive to changing driving conditions. The suppression unit dynamically adjusts whether to suppress driving support based on real-time inputs from the shift device state and timing information. This dynamic approach allows the system to respond appropriately to different driving situations, preventing both unnecessary suppression and unnecessary activation of driving support.
2Reliability
If the driving support is not suppressed when the steering angle is equal to or greater than a predetermined angle, then necessary driving support is maintained, but unnecessary driving support may be exercised in actual running situations
Solution Approach 1:
The patent applies local quality by differentiating the suppression logic based on specific driving conditions. Instead of uniformly suppressing driving support when steering angle exceeds the threshold, the system selectively suppresses support only in specific scenarios (e.g., when shift device is in non-driving range or within a predetermined time after shift) while maintaining support in other scenarios. This localized application of suppression resolves the contradiction by ensuring necessary support is not suppressed.
Solution Approach 2:
The patent implements feedback by continuously monitoring the shift device state and timing information to determine whether suppression should be applied. The suppression unit receives feedback from the state detection unit about current driving conditions and adjusts its suppression decision accordingly. This feedback mechanism ensures that driving support is suppressed only when appropriate while maintaining support when needed.
3Reliability
If the suppression of driving support is inhibited without exception when the steering angle is equal to or greater than a predetermined angle, then necessary driving support is maintained, but driver discomfort increases due to frequent unnecessary driving support
Solution Approach 1:
The patent applies local quality by differentiating the suppression logic based on specific driving conditions. Instead of uniformly suppressing driving support when steering angle exceeds the threshold, the system selectively suppresses support only in specific scenarios (e.g., when shift device is in non-driving range or within a predetermined time after shift) while maintaining support in other scenarios. This localized application of suppression resolves the contradiction by ensuring necessary support is not suppressed.
Solution Approach 2:
The patent implements parameter changes by introducing additional decision parameters beyond the steering angle threshold. The suppression unit considers multiple parameters including shift device state and time information to dynamically adjust the suppression decision. This multi-parameter approach allows the system to optimize both reliability and driver comfort by suppressing support only when appropriate conditions are met.

AI summary
A vehicle (100) includes a support control unit (111) that supports avoidance of a. collision with an object and a support suppressing unit (112) that suppresses the support of the support control unit (111) when a steering angle of the vehicle (100) is equal to or greater than a predetermined angle. The vehicle (100) further includes an intervention limiting unit (113) that determines whether the support suppression of the support suppressing unit (112) is necessary when the steering angle is equal to or greater than the predetermined angle on the basis of vehicle information acquired from the vehicle (100) or a running environment of the vehicle (100) and that limits intervention of the support suppression of the support suppressing unit (112) depending on the determination result.
