Autonomous Driving Control Planning Under Map Data Inconsistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving systems face challenges in calculating accurate potential accident liability values due to incomplete or outdated map data, leading to unexpected vehicle behavior and user confusion when map data acquisition fails or becomes inconsistent with the real world.
Innovation Solution
An automatic driving device that includes a map management unit to determine the acquisition status of map data and a control planning unit to generate and adjust control plans accordingly, ensuring user-perceptible interruptions during map inconsistencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map data is used for automatic driving control planning, then the control plan can be generated based on road structure and safety distance, but the system becomes vulnerable to user confusion when map data acquisition fails or becomes inconsistent
Solution Approach 1:
The system performs preliminary determination of map data acquisition status before generating the control plan. The map management unit checks whether map data is properly acquired and consistent with the real world in advance, allowing the system to prepare appropriate responses (such as notifying the user or switching to alternative control methods) before map inconsistencies cause confusion.
Solution Approach 2:
The system establishes a feedback loop where the map management unit continuously monitors the acquisition status of map data and provides this information to the control planning unit. When map data becomes inconsistent or unavailable, the system feeds back this status information and adjusts the control plan accordingly, preventing user confusion by maintaining transparent communication about system limitations.
2Object-affected harmful factors
If the system continuously monitors map data acquisition status, then user confusion can be reduced, but the device complexity increases
Solution Approach 1:
The map management unit is designed to perform multiple functions: it not only determines the acquisition status of map data but also manages the map data itself and communicates with the control planning unit. This multi-functional design reduces the need for separate dedicated monitoring components, thereby reducing overall system complexity while maintaining continuous monitoring capabilities.
3Reliability
If the control plan is changed according to map data acquisition status, then driving safety can be maintained, but the ease of operation decreases due to frequent plan adjustments
Solution Approach 1:
The control planning unit dynamically adjusts the control plan based on the current map data acquisition status. When map data is complete and consistent, the system uses standard control plans optimized for safety and efficiency. When map data becomes incomplete or inconsistent, the system automatically transitions to alternative control strategies that rely less on map data, maintaining driving safety while adapting to changing conditions.
