Automatic Parking Route Simplification for Orientation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems generate training data with unnecessary routes when users turn back and forth to adjust vehicle orientation, leading to inefficient automatic parking operations.
Innovation Solution
A driving assistance apparatus that generates training data by connecting points on the traveling route where the vehicle's orientation difference is less than a threshold and the distance is less than another threshold, eliminating unnecessary turns and optimizing the target route for automatic parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle turns back and forth to adjust orientation during training traveling, then the vehicle can reach the target parking position, but unnecessary routes are generated increasing traveling distance and time
Solution Approach 1:
The patent extracts and removes unnecessary routes from the training traveling data. The route generation unit identifies and eliminates redundant back-and-forth movements, keeping only the essential path from start to target position, thereby reducing traveling time while maintaining orientation adjustment capability
Solution Approach 2:
The patent performs preliminary processing of the training route before actual automatic parking execution. The route generation unit pre-processes the training traveling data to generate an optimized target route, so that when automatic parking is executed, the vehicle follows the pre-optimized path without unnecessary detours
2Ease of operation
If the vehicle turns back and forth to adjust orientation during training traveling, then the vehicle can reach the target parking position, but the traveling route becomes longer and less efficient
Solution Approach 1:
The patent extracts and removes unnecessary routes from the training traveling data. The route generation unit identifies and eliminates redundant back-and-forth movements, keeping only the essential path from start to target position, thereby reducing traveling time while maintaining orientation adjustment capability
Solution Approach 2:
The patent performs preliminary processing of the training route before actual automatic parking execution. The route generation unit pre-processes the training traveling data to generate an optimized target route, so that when automatic parking is executed, the vehicle follows the pre-optimized path without unnecessary detours
3Adaptability or versatility
If the training data includes unnecessary routes from back-and-forth turning, then the vehicle can learn orientation adjustment, but the automatic parking operation becomes less precise
Solution Approach 1:
The patent extracts and removes unnecessary routes from the training traveling data. The route generation unit identifies and eliminates redundant back-and-forth movements, keeping only the essential path from start to target position, thereby reducing traveling time while maintaining orientation adjustment capability
Solution Approach 2:
The patent applies different processing quality to different parts of the route. The route generation unit identifies specific sections with unnecessary back-and-forth movements and optimizes only those local segments, while preserving the overall route structure and essential orientation adjustment portions

AI summary
A driving assistance method of performing automatic traveling of a vehicle based on a driving operation of a user is provided. The driving assistance method: stores a traveling route traveled by the vehicle according to the driving operation of the user in a training traveling mode; displays the traveling route from a traveling start position to a target parking position in the training traveling mode; and displays a target route from the traveling start position to the target parking position in an automatic traveling mode. The target route in the automatic traveling mode is shorter than the traveling route in the training traveling mode, and a first number of turns of the vehicle in the training traveling mode is same as a second number of turns of the vehicle in the automatic traveling mode.
