Vehicle Driving Support System Avoiding Unnecessary Intervention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving support systems often provide assistance regardless of the driver's intention, leading to unnecessary support that may trouble the driver and fail to account for the driver's ability to avoid obstacles through normal driving operations.
Innovation Solution
A vehicular driving support system that determines the future travel range based on the driver's normal driving operations, providing support only when no avoidance route is available within that range, using sensors to recognize obstacles and adjust support measures based on the driver's movement parameters and vehicle speed.

Engineering Contradiction Analysis
1Reliability
If driving support is provided whenever a solid body is detected within a threshold distance, then collision avoidance capability is improved, but unnecessary support is provided that may trouble the driver
Solution Approach 1:
The system changes the parameter of support provision from a fixed threshold-based approach to a dynamic approach that considers the driver's normal operational parameters. By calculating the traveling range based on the driver's current movement amount and normal operational variations, the system adapts the support provision criteria to match the driver's actual capabilities and intentions, reducing unnecessary support while maintaining collision avoidance.
Solution Approach 2:
The system incorporates feedback by continuously monitoring the driver's movement amount and comparing it with normal operational patterns. This feedback mechanism allows the system to determine whether the driver is performing normal driving operations or requires assistance, thereby providing support only when necessary and avoiding unnecessary interventions that would trouble the driver.
2Device complexity
If driving support is provided based on fixed threshold distance, then system simplicity is maintained, but driver's ability to avoid obstacles through normal driving operations is not considered
Solution Approach 1:
The system transitions from a static fixed-threshold approach to a dynamic evaluation method that continuously assesses the driver's movement amount and normal operational parameters. By calculating the traveling range based on real-time driver behavior data, the system adapts to different driving styles and conditions while maintaining reasonable computational complexity through efficient algorithms.
Solution Approach 2:
The system performs preliminary calculations of the traveling range and normal operational parameters in advance, storing these values for quick reference during critical moments. This preliminary action allows the system to rapidly determine whether support is needed without complex real-time computations, maintaining system simplicity while achieving adaptability to driver behavior.
3Ease of operation
If the traveling range is calculated based on driver's normal operational parameters, then unnecessary support is reduced, but calculation complexity increases
Solution Approach 1:
The system uses the driver's own movement data and operational patterns to self-determine when support is needed, eliminating the need for complex external judgment criteria. By leveraging the driver's normal operational parameters as the basis for traveling range calculation, the system reduces unnecessary support provision while keeping calculations relatively simple and data-driven.

AI summary
It is a task of the invention to provide an art that makes it possible to provide driving support suited for the feeling of a driver in a system that supports the avoidance of a collision of a vehicle. In order to achieve this task, according to the invention, in a system that supports the avoidance of a collision of a vehicle, a traveling range as a range of a route on which a host vehicle is to travel in a range of a driving operation to be normally performed by a driver is obtained, driving support is not provided if there is a route that allows a solid body to be avoided within the traveling range, and driving support is provided if there is no route that allows the solid body to be avoided within the traveling range.
