Towing Assistance Path Planning for Angle-Aware Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing towing assistance systems require complex calculations to generate multiple paths based on the positional relationship between the towing vehicle and the target stop position, increasing computational cost and difficulty in path generation, especially when considering parking angles.
Innovation Solution
A towing assistance apparatus that includes a detection unit to identify parking regions and a computation unit to generate a target path comprising a forward and backward path based on predefined stop positions, calculating deviation amounts to simplify path generation regardless of parking angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple backward paths are generated based on positional relationships between towing vehicle and target stop position, then path selection accuracy is improved, but calculation cost increases
Solution Approach 1:
The system pre-calculates and stores multiple backward path patterns in advance, so that during actual towing assistance, the computation unit only needs to select from pre-generated patterns rather than calculating all possible paths in real-time. This reduces calculation cost while maintaining path selection accuracy
Solution Approach 2:
The path generation problem is segmented into two parts: (1) pre-generation of backward path patterns stored in the storage unit, and (2) real-time selection and combination with forward trajectories. This segmentation allows complex path calculations to be performed offline, reducing real-time computational burden
2Measurement precision
If multiple backward paths are generated considering parking angles, then path accuracy is improved, but path generation difficulty increases
Solution Approach 1:
Multiple backward path patterns covering different parking angle scenarios are pre-calculated and stored. During operation, the system simply selects the appropriate pre-generated pattern based on the current parking angle, avoiding complex real-time calculations while maintaining high path accuracy
Solution Approach 2:
The system handles different parking angles by selecting from pre-generated path patterns that correspond to different angle parameters. This approach manages complexity by organizing solutions according to parameter variations rather than calculating each scenario from scratch

AI summary
A towing assistance apparatus assists backward parking of a towing vehicle towing a towed vehicle. The towing assistance apparatus includes: a detector configured to detect a parking region having an entrance on a lateral side of the towing vehicle; and a calculator configured to generate a target path including a forward and backward path of the towing vehicle based on a default stop position and path set in advance The calculator calculates a first deviation amount in a front-rear direction of the towing vehicle between a target stop position determined based on the parking region and the default stop position, and a second deviation amount in the front-rear direction of the towing vehicle generated according to a parking angle when the towing vehicle is parked, and the forward path generated based on a sum of the first and second deviation amounts.
