Parking Assist Route Recalculation and Obstacle Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assist systems fail to appropriately notify users when a vehicle stops traveling along a target route due to obstacles, leading to potential safety and convenience issues.
Innovation Solution
A parking assist system that includes an acquiring unit for surrounding information, a display unit, and a control unit capable of calculating alternative routes and displaying notifications to the user based on the success or failure of recalculating a route around obstacles, allowing the system to switch the vehicle's direction and start traveling without user intervention if safe to do so.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops traveling along the target route due to obstacle detection, then safety is improved by avoiding collision, but the user is not appropriately notified of the vehicle's behavior
Solution Approach 1:
The system implements feedback by notifying the user through the display unit when the vehicle stops due to obstacle detection. The control unit determines whether to display surrounding information or operation method notifications, ensuring the user is informed of the vehicle's stopped state and the reasons behind it, thus maintaining safety while improving information feedback to the user.
2Loss of information
If the system displays surrounding information when calculating alternative route, then user awareness is improved, but the display may not provide sufficient guidance when route recalculation fails
Solution Approach 1:
The display unit dynamically changes its content based on the route calculation outcome. When alternative route calculation succeeds, it displays surrounding information to maintain user awareness. When calculation fails, it switches to displaying operation method notifications to provide clear guidance on what the user should do, thus adapting to different operational states.
Solution Approach 2:
The control unit acts as an intermediary that determines what information to display based on the route calculation result. It mediates between the obstacle detection system and the display unit, selecting appropriate notification types to ensure both user awareness and ease of operation are maintained.
3Ease of operation
If the vehicle automatically starts traveling along the alternative route, then user convenience is improved by reducing intervention, but safety may be compromised without user confirmation
Solution Approach 1:
The system provides self-service by automatically calculating and executing alternative routes when obstacles are detected, reducing the need for user intervention. The control unit autonomously determines the next actions based on obstacle information and route calculation results, improving convenience while maintaining safety through continuous monitoring and appropriate user notifications.

AI summary
A parking assist system includes an acquiring unit, a display unit, and a control unit. In a case where the acquiring unit acquires information about an obstacle on a first target route during traveling of a vehicle along the first target route and thus the vehicle stops traveling along the first target route, the control unit tries to calculate a second target route to a target position from a position where the vehicle stops traveling along the first target route. Upon succeeding in calculating the second target route, the control unit causes the display unit to display surrounding information corresponding to the second target route. Upon failing to calculate the second target route, the control unit causes the display unit to display a notification about an operation method of the vehicle.
