Automatic Parking Route Generation from Training Driving Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems generate training routes with unnecessary turns and deviations, leading to inefficient automatic parking operations.
Innovation Solution
A driving assistance apparatus that generates a target route by connecting points on the training route where the vehicle's orientation difference and distance are within certain thresholds, eliminating unnecessary turns and optimizing the path for automatic parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle travels back and forth to change traveling direction during training traveling, then the vehicle can reach the parking space, but the traveling route includes unnecessary routes that increase travel 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 traveling segments, keeping only the essential path from the initial position to the parking space, thereby reducing travel time while maintaining maneuverability
Solution Approach 2:
Instead of directly recording the actual training traveling route with all its inefficiencies, the system inverts the approach by generating an optimized route from the training data. It reconstructs the route by connecting key position points directly, rather than following the original inefficient path, thus achieving time savings
2Extent of automation
If the system uses the original training traveling route as the target route, then the automatic parking can be executed, but the vehicle performs unnecessary traveling every time
Solution Approach 1:
The system performs preliminary route optimization during the training phase. The route generation unit pre-processes the training traveling data to create an optimized target route that eliminates unnecessary segments. This preliminary action ensures that subsequent automatic parking operations execute efficiently without repeating wasted travel
Solution Approach 2:
The system creates an optimized copy of the training route rather than using the original. The route generation unit generates a new target route that copies only the essential positioning information from the training data, eliminating redundant segments while preserving the necessary parking maneuver information

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.
