Parking Assistance Start Timing Using Position and Azimuth Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance technologies face challenges in efficiently preparing for parking assistance before a vehicle arrives near a target parking position, often leading to delayed automatic parking and user annoyance.
Innovation Solution
A parking assistance method that uses a travel route generated from teaching travel by a driver to determine if the vehicle is oriented correctly at a prescribed position, allowing for early preparation and notification for starting parking assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If parking assistance preparations are started early before the vehicle arrives near the target parking position, then the productivity of the parking process is improved, but the user may be annoyed by unnecessary guidance notifications
Solution Approach 1:
The system performs preliminary actions by determining in advance whether the vehicle is approaching a target parking position based on stored position information and current position data. This allows the system to prepare for parking assistance notifications only when appropriate, rather than continuously or过早, thus improving productivity while avoiding unnecessary user annoyance.
Solution Approach 2:
The system uses feedback mechanisms by continuously monitoring the vehicle's current position against stored target parking position information. This feedback loop enables the system to intelligently determine when to activate parking assistance notifications, ensuring they are provided at appropriate moments rather than causing unnecessary annoyance to users.
2Measurement precision
If the vehicle position is continuously monitored to determine when to start parking assistance, then the measurement precision of vehicle position is improved, but the loss of time for processing position data increases
Solution Approach 1:
The system performs preliminary actions by storing target parking position information in advance during teaching travel. This pre-stored information is then used for quick comparison with current position data, eliminating the need for complex real-time analysis and thus reducing processing time while maintaining high measurement precision.
Solution Approach 2:
The system creates a copy of the target parking position information and stores it for future reference. This copied position data can be quickly compared with current vehicle position without requiring repeated complex calculations, thereby reducing processing time while maintaining accurate position detection.

AI summary
A parking assistance method according to the present disclosure is a method of performing autonomous travel of a vehicle based on a travel route generated using teaching travel by a driver. The parking assistance method includes: acquiring a position of the vehicle and an azimuth in a travel direction of the vehicle; outputting, based on the position and the azimuth in the travel direction, when the vehicle is located and oriented with a prescribed azimuth in a prescribed position, a notification to a user to prompt an operation to start parking assistance; and receiving the operation by the user to start the parking assistance. The prescribed position is located within a range of a prescribed distance from a start position of the travel route.
