Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving assistance apparatuses are installed to improve driver convenience, then the functionality and assistance coverage are improved, but the consistency between assistance contents deteriorates
Solution Approach 1:
The driving assistance apparatus integrates multiple assistance functions (acceleration assistance, deceleration assistance, collision avoidance assistance) into a single system that can perform various driving assistance tasks. The system uses a unified assistance determination approach across different assistance types, ensuring consistent behavior while providing diverse functionality.
Solution Approach 2:
The system determines whether acceleration/deceleration assistance should be provided based on the predicted state of collision avoidance assistance. This feedback mechanism ensures that assistance contents are coordinated and consistent, preventing conflicting assistance actions while maintaining comprehensive functionality.
2Productivity
If acceleration assistance is provided to improve driving efficiency, then the productivity is improved, but the driver comfort deteriorates due to sudden deceleration assistance afterward
Solution Approach 1:
The system predicts the state of collision avoidance assistance in advance and uses this prediction to determine whether to provide acceleration or deceleration assistance. By performing this prediction beforehand, the system avoids sudden switches between acceleration and deceleration assistance, thereby maintaining driver comfort while preserving driving efficiency.
Solution Approach 2:
The system dynamically adjusts the type of assistance provided (acceleration or deceleration) based on the predicted collision avoidance assistance state. This dynamic adjustment ensures smooth transitions between different assistance modes, preventing abrupt changes that would discomfort the driver while maintaining optimal driving efficiency.

AI summary
A driving support apparatus for ensuring consistency of content for multiple driving supports related to vehicle acceleration/deceleration. The driving support apparatus is provided with a follow-up running support unit for performing acceleration/deceleration support for a vehicle. A collision-avoidance support unit avoids a collision with a moving body when the relationship between the vehicle and a moving body having a movement path intersecting with the path of the vehicle is determined to meet support conditions for invoking collision-avoidance support. An estimation unit estimates that the relationship between the vehicle and the moving body meets the support conditions for invoking collision-avoidance support using the acceleration/deceleration support by the follow-up running support unit. An adjustment unit adjusts the degree of acceleration/deceleration support by the follow-up running support unit on the basis of the relationship between the vehicle and the moving body having been estimated to meet the support conditions.
