Automated Vehicle Driving Mode Switching for Map Error Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control technologies fail to flexibly change driving control when map information and recognized external world information differ, leading to potential inaccuracies in steering and acceleration.
Innovation Solution
A vehicle control device and method that determines driving modes based on surrounding situations, using a hardware processor to recognize errors in map information and adjust control modes by following a preceding vehicle's trajectory, maintaining recognizable road lane markings and trajectories for safe driving support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the vehicle continues the second driving mode when map information and recognized external world information differ, then the driving control remains stable and continuous, but the accuracy of steering and acceleration control deteriorates
Solution Approach 1:
The system dynamically adjusts the driving mode based on real-time conditions. When map information and recognized external world information differ and no preceding vehicle is detected, the system transitions from the second driving mode (with lighter driver task) to the first driving mode (with heavier driver task), enabling flexible adaptation to information discrepancies while maintaining control stability through controlled mode transitions
2Measurement precision
If the vehicle changes to the first driving mode when map information error is detected, then the control accuracy is improved, but the driver's task burden increases
Solution Approach 1:
The system implements feedback by continuously monitoring the presence of preceding vehicles and the consistency between map information and recognized external world information. When a preceding vehicle is detected within a predetermined distance, the system feedback-indicates that the second driving mode can be maintained, thereby improving ease of operation while preserving control accuracy through informed mode selection
3Reliability
If the vehicle uses map information for driving control, then the driving control is accurate and reliable, but the system cannot adapt when map information is erroneous
Solution Approach 1:
The system introduces an intermediary mechanism by using the recognized external world information and preceding vehicle detection as mediators between the map information and the driving control. When map information and recognized information differ, the system uses the detected surrounding situation (particularly preceding vehicle presence) as an intermediary to determine whether to maintain or change driving mode, enabling adaptation to map information errors while preserving reliability through multi-source information validation

AI summary
A vehicle control device recognizes a surrounding situation of a vehicle, controls steering and acceleration or deceleration of the vehicle without depending on an operation of a driver of the vehicle based on the surrounding situation and map information, determines a driving mode of the vehicle to be one of a plurality of driving modes including a first driving mode and a second driving mode, determines whether there is an error in the map information based on the surrounding situation and the map information, and in a case where an error is determined in the map information while the vehicle is driving in the second driving mode, continues the second driving mode when a preceding vehicle is recognized within a first predetermined distance, or changes the second driving mode to the first driving mode when a preceding vehicle is not recognized within the first predetermined distance.
