Multilevel Parking Route Mapping for Correct Floor Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maneuvering systems in multi-story parking areas suffer from reduced comfort and reliability due to erroneous automated maneuver offers, often caused by insufficient GNSS and image data in distinguishing between similar-looking floors, leading to incorrect maneuver suggestions.
Innovation Solution
A maneuvering system that records a driving trajectory and floor information using GNSS, odometry, and incline data, allowing precise localization and ensuring automated maneuvers are performed on the correct floor by verifying the vehicle's position relative to the stored trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated maneuvering is offered based on GNSS and image data in multi-story parking areas, then the convenience of automated parking is improved, but the reliability deteriorates due to erroneous offers on incorrect floors
Solution Approach 1:
The patent adds a vertical dimension (floor level) to the positioning system by combining GNSS horizontal coordinates with incline sensor data to determine the third dimension. This allows the system to distinguish between identical parking areas on different floors, resolving the reliability issue while maintaining automated maneuver convenience.
Solution Approach 2:
The patent introduces an intermediary evaluation unit that processes and combines multiple data sources (GNSS coordinates, image data, and incline information) to determine floor level. This intermediary layer filters and validates data before activation decisions, preventing erroneous offers while enabling reliable automated maneuvering.
2Reliability
If multiple sensors are combined to determine floor level accurately, then the reliability of automated maneuvers is improved, but the device complexity increases
Solution Approach 1:
The patent utilizes the vehicle's existing incline sensor, which is already part of the vehicle's standard equipment for other purposes. By repurposing this existing sensor for floor level determination, the system achieves multi-dimensional positioning without adding external hardware, thus maintaining reliability while minimizing increased complexity.
Solution Approach 2:
The evaluation unit is designed to handle multiple functions: processing GNSS data, analyzing image data, evaluating incline information, and making activation decisions. This multi-functional approach consolidates what could be separate complex systems into a single integrated unit, improving reliability without proportionally increasing overall system complexity.

AI summary
A routing system for automatically routing a motor vehicle is designed to record a drive trajectory for a routing maneuver in a parking area in a recording mode on the basis of a route being traversed by a driver by means of the motor vehicle in a manual driving operation, said parking area having multiple levels. The routing system is additionally designed to store first level information for describing a level of the parking area in which the traversed route is arranged in combination with the recorded travel trajectory. Furthermore, the routing system is designed to use the recorded travel trajectory and the first level information for an automated routing maneuver in an automated mode.
