Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers experienced in automatic parking feel inconvenience due to a corrected target vehicle speed being set too low, leading to decreased feelings of anxiety and discomfort during parking.
Innovation Solution
A parking assistance device that increases vehicle speed during parking based on previous parking behaviors, such as brake operation frequency and elapsed time, to adjust the target vehicle speed upper limit, thereby reducing driver inconvenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the target vehicle speed is corrected to a lower speed for safety during automatic parking, then the safety of the vehicle is improved, but the driver feels inconvenience and discomfort
Solution Approach 1:
The patent applies dynamics by making the target vehicle speed adjustable and adaptive rather than fixed. The system dynamically changes the speed parameter based on driver behavior patterns, transitioning from a static safety-oriented speed limit to a dynamic speed profile that responds to actual driver needs and experience level.
Solution Approach 2:
The patent implements feedback by monitoring driver behavior (brake operations, accelerator operations) during automatic parking and using this information to adjust the target vehicle speed. The system continuously observes driver responses and modifies speed parameters accordingly, creating a closed-loop control system that balances safety and driver comfort.
2Ease of operation
If the target vehicle speed is increased to improve driver comfort, then the driver convenience is improved, but the safety during parking is reduced
Solution Approach 1:
The system uses dynamics to adjust vehicle speed based on real-time driver behavior rather than maintaining a fixed speed. The target speed becomes a dynamic parameter that increases or decreases according to the driver's operational patterns, allowing the system to adapt speed levels to match driver confidence and skill.
Solution Approach 2:
The patent employs feedback mechanisms where the system monitors driver actions (such as brake and accelerator operations) and uses this information to adjust the target vehicle speed. This feedback loop enables the system to increase speed when driver behavior indicates confidence and comfort, while maintaining safety through continuous monitoring.
3Reliability
If the target vehicle speed is kept low at the start of automatic parking control, then the safety is improved for inexperienced drivers, but the experienced drivers feel inconvenience
Solution Approach 1:
The patent applies dynamics by implementing a adaptive speed system that transitions from static to dynamic based on driver experience. The target vehicle speed is no longer a fixed conservative value but evolves over time based on accumulated driver behavior data, allowing the system to adapt its characteristics to match the driver's experience level.
Solution Approach 2:
The system uses feedback from driver behavior patterns to determine the driver's experience level and adjust the target vehicle speed accordingly. By monitoring whether drivers perform brake operations or accelerator operations during automatic parking, the system learns and adapts its speed parameters to suit individual driver needs and experience.
