Adaptive Backing Guidance for Side Obstacle Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backing assistance systems fail to effectively assist drivers in parking at an appropriate distance from obstacles on the side of the vehicle.
Innovation Solution
A backing assistance apparatus that monitors seat usage on both sides of the vehicle, sets reference distances based on seat usage, and displays a guide element on a rearview screen indicating the appropriate distance from detected obstacles during reversing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional backing assistance systems are used, then basic rear view monitoring is provided, but the system cannot assist in parking at appropriate distance from side obstacles
Solution Approach 1:
The assistance system is segmented into multiple functional modules: seat usage detection module, obstacle detection module, reference distance setting module, and guide element display module. Each module independently processes specific aspects of the parking assistance function, allowing the system to provide targeted guidance for different seating configurations and obstacle scenarios.
Solution Approach 2:
The system performs preliminary detection of seat usage status before the backing maneuver begins. Based on this preliminary information, the system pre-calculates and sets appropriate reference distances for guide elements, ensuring that the correct safety margins are applied before the vehicle starts moving backward.
2Adaptability or versatility
If fixed reference distance is used for backing assistance, then simple display is achieved, but the system cannot adapt to different seat usage scenarios
Solution Approach 1:
The reference distance is made dynamic rather than fixed. The system automatically adjusts the reference distance based on real-time seat usage detection, differentiating between cases where occupants are present or absent. This dynamic adaptation allows the system to handle various seating scenarios without requiring manual configuration or complex user input.
Solution Approach 2:
The system performs self-configuration by automatically detecting seat usage status and setting appropriate reference distances without requiring user intervention. The controller autonomously determines the correct safety margins based on detected occupancy patterns, eliminating the need for manual distance setting by the driver.
3Manufacturing precision
If no seat usage monitoring is implemented, then simple system structure is maintained, but appropriate reference distance cannot be determined
Solution Approach 1:
The seat usage monitoring system serves multiple functions: it detects occupancy status, determines which seats are in use, and provides this information to the distance calculation module. This multi-functional approach allows a single monitoring system to support both safety assessment and precise distance determination without requiring separate dedicated systems.

AI summary
A backing assistance apparatus includes a controller configured to monitor a usage of each seat on a driver side and a passenger side of a vehicle, set a reference distance on each of the driver side and the passenger side according to the usage, and upon detecting an obstacle on a side of a space to which the vehicle is predicted to proceed when the vehicle is backing, display, on a screen that shows an image of a rear of the vehicle to assist in backing the vehicle, a guide element indicating a position that is distant from the detected obstacle by the reference distance.
