Multi-Maneuver Vehicle Park Assist System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle park assist systems cannot effectively identify and assist with parking in spaces that are too small for a single maneuver but large enough for multiple maneuvers, leaving drivers uncertain about the necessary steering trajectories.
Innovation Solution
A park assist system that uses a sensing system with ultrasonic sensors, GPS, and odometric sensors to determine the feasibility of a parking space and prompts the driver to execute calculated steering trajectories for multiple maneuvers, allowing the system to take over steering control for successful parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the park assist system only identifies parking spaces suitable for single maneuver parking, then the reliability of parking completion is improved, but the quantity of available parking spaces is reduced
Solution Approach 1:
The patent segments the parking maneuver into multiple discrete steps (first maneuver, second maneuver, etc.) rather than requiring a single continuous motion. The system divides the parking process into separate executable trajectories, allowing spaces that would be too small for one maneuver to be utilized through sequential maneuvers with intermediate stopping points.
2Ease of operation
If the system provides automated steering for single maneuver parking, then the ease of operation is improved, but the adaptability to different parking space sizes is reduced
Solution Approach 1:
The system dynamically adapts the parking strategy based on the detected slot length. When a space is detected to be suitable for multi-maneuver parking, the system automatically generates and executes a sequence of steering trajectories rather than a single trajectory, allowing the same automated steering system to handle both small and large parking spaces effectively.

AI summary
A park assist system for parking a vehicle in a target parking space includes a sensing system. The sensing system determines whether there is a sufficient slot length in a target parking space too small to complete a parking maneuver in a single maneuver, but large enough to complete a parking maneuver in more than one maneuver. During each of the more than one parking maneuvers, the driver is prompted to execute a calculated steering trajectory.
