Autonomous Vehicle Positioning Correction for Volume Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for providing position information of autonomous vehicles do not accurately account for changes in vehicle volume, such as when baggage is loaded or a door is opened, leading to potential safety risks due to inaccurate positioning.
Innovation Solution
An apparatus and method that utilize a processor to acquire position information from an antenna installed in the vehicle, generate position data, and correct it based on changes in the vehicle's external appearance, such as door openings or passenger entry/exit, to provide precise positioning information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If position information is provided based on antenna location only, then the positioning system is simple, but the position accuracy deteriorates when vehicle volume changes
Solution Approach 1:
The system pre-stores multiple position data sets corresponding to different vehicle volumes (e.g., with/without baggage, doors open/closed) in advance. When a volume change occurs, the processor selects and applies the appropriate pre-calculated position data set, avoiding real-time complex calculations while maintaining high position accuracy.
Solution Approach 2:
The positioning system dynamically adapts to changing vehicle conditions by detecting volume changes (through sensors or image processing) and switching between different position data sets. This makes the system flexible and responsive to real-time vehicle state changes without requiring complete recalculation.
2Quantity of substance
If the vehicle volume is increased (e.g., loading baggage), then the cargo capacity is improved, but the position information accuracy deteriorates
Solution Approach 1:
Position data sets for different cargo loading scenarios are pre-calculated and stored. When baggage is loaded, the system detects the volume change and retrieves the corresponding position data set, ensuring accurate position information without requiring recalculation during cargo operations.
Solution Approach 2:
The system continuously monitors vehicle state (through sensors detecting door status, cargo presence) and uses this feedback to select the appropriate position data set. This closed-loop approach ensures position accuracy is maintained regardless of cargo capacity changes.
3Ease of operation
If door is opened, then the accessibility is improved, but the position data accuracy deteriorates
Solution Approach 1:
Position data sets accounting for door open/closed states are pre-prepared. When a door is opened (detected by sensors), the system immediately switches to the position data set corresponding to the door-open configuration, maintaining accuracy without interrupting the door operation.
Solution Approach 2:
The system dynamically adjusts position data based on real-time door status detection. This allows seamless transition between different door configurations while maintaining accurate position information for safety and navigation purposes.
4Device complexity
If conventional position information is provided without considering volume changes, then the system simplicity is maintained, but the safety deteriorates
Solution Approach 1:
Multiple position data sets for different safety-critical scenarios are pre-calculated and stored. The system maintains simplicity by selecting from these pre-prepared data sets based on detected conditions, rather than performing complex real-time calculations, thereby ensuring both safety and system simplicity.
Solution Approach 2:
The system uses sensor feedback to detect changes in vehicle state that affect safety (volume changes, door status) and automatically selects the appropriate position data set. This feedback mechanism ensures safety is maintained without requiring complex real-time processing.

AI summary
Disclosed is an apparatus for generating position data including a processor which acquires position information of an antenna installed in a vehicle, generates position data of the vehicle based on the position information of the antenna, acquires information about change in an external appearance of the vehicle, and corrects the position data of the vehicle based on the information about the change in the external appearance of the vehicle.
