Vehicle Trajectory Guidance by Type-Specific Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous parking systems lack efficiency in navigating vehicles of different types and sizes within parking lots, as they use general target trajectories that do not account for specific vehicle features, leading to suboptimal navigation and parking experiences.
Innovation Solution
A method and device that determine a target trajectory tailored to each vehicle type based on its unique parameters, such as wheelbase, height, and sensor system inaccuracies, allowing for optimized autonomous navigation and parking by sending the trajectory via a communication network, enabling the vehicle to drive independently within the parking lot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a general target trajectory is used for all vehicles, then the system complexity is reduced and data transmission is simplified, but the navigation accuracy and parking efficiency deteriorate due to inability to account for specific vehicle characteristics
Solution Approach 1:
The patent applies local quality by customizing the target trajectory according to each vehicle's specific characteristics (vehicle type, dimensions, sensor accuracy). Instead of using a uniform trajectory for all vehicles, the system adapts the trajectory parameters locally to match each vehicle's unique properties, thereby improving navigation accuracy without requiring complete system redesign
Solution Approach 2:
The patent implements parameter changes by adjusting trajectory parameters based on vehicle-specific data. The system modifies trajectory characteristics (such as turning radius, speed profiles, positioning points) according to vehicle dimensions and sensor accuracy, allowing the same basic trajectory framework to serve multiple vehicle types with optimized performance for each
2Productivity
If vehicle-specific target trajectories are determined for each vehicle type, then the navigation accuracy and parking efficiency are improved, but the data transmission volume and processing requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing target trajectories for different vehicle types before actual parking operations. The system prepares vehicle-specific trajectory data in advance based on vehicle characteristics, so that during actual parking operations, the vehicle only needs to receive and execute pre-prepared trajectory data rather than having complex real-time calculations performed
Solution Approach 2:
The patent implements universality by creating a standardized framework that can serve multiple vehicle types. Instead of developing completely separate trajectory systems for each vehicle model, the system uses a universal trajectory generation approach that adapts to different vehicle types through parameter adjustment, reducing overall data volume while maintaining vehicle-specific optimization
3Ease of operation
If autonomous driving is implemented without vehicle-specific trajectory adaptation, then the ease of operation is improved and setup is simplified, but the loss of time occurs due to suboptimal navigation routes
Solution Approach 1:
The patent applies self-service by enabling the vehicle to autonomously receive and execute its own vehicle-specific target trajectory without requiring manual configuration or complex real-time adjustments. The vehicle automatically identifies its type, receives the appropriate pre-calculated trajectory, and executes it independently, maintaining ease of operation while optimizing navigation time through vehicle-specific path optimization
