Vehicle Control System Switching Between White Line and Track Tracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to provide appropriate travel control when an emergency vehicle is present, as they do not effectively switch between white line tracing and track tracing to prioritize emergency vehicle passage.
Innovation Solution
A vehicle control system that includes an obtainment unit for periphery information, a determination unit to detect emergency vehicles, and a control unit to switch between travel control states based on white line tracing and track tracing, prioritizing track tracing when an emergency vehicle is approaching to create a travel space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle prioritizes white line tracing for travel control, then lane discipline is maintained, but emergency vehicles cannot pass efficiently
Solution Approach 1:
The system dynamically switches between white line tracing and track tracing modes based on the detection of emergency vehicles. When an emergency vehicle is detected, the system transitions from rigid white line adherence to flexible track tracing, allowing the vehicle to follow other vehicles and create passage space for emergency vehicles while maintaining normal lane discipline during regular operation
2Productivity
If the vehicle switches to track tracing when emergency vehicles are present, then emergency passage is enabled, but lane position precision is reduced
Solution Approach 1:
The system employs dynamic mode switching between white line tracing (high precision lane positioning) and track tracing (flexible emergency passage). The control unit selects the appropriate tracing mode based on emergency vehicle detection, thereby maintaining high lane position accuracy during normal operation while enabling efficient emergency passage when needed
3Stability of the object's composition
If the vehicle maintains fixed travel control based on white lines, then travel stability is ensured, but adaptability to emergency situations is reduced
Solution Approach 1:
The system transforms fixed white line-based travel control into a dynamic system that can adapt between two modes: white line tracing for stable normal operation and track tracing for emergency situations. This dynamic adaptability allows the vehicle to maintain travel stability during routine driving while responding effectively to emergency vehicles through mode switching
Solution Approach 2:
The system uses feedback from the periphery information acquisition unit to detect emergency vehicles and automatically switches between control modes. This feedback mechanism enables the system to respond to changing environmental conditions, maintaining stability during normal operation while adapting to emergency situations through automated mode transitions

AI summary
A control system of a vehicle that can travel in a first state in which travel control is performed based on a position of a white line on a travel lane and in a second state in which travel control is performed based on a travel position of another vehicle. Periphery information is obtained of the vehicle. It is determined, based on the periphery information obtained, whether an emergency vehicle is approaching. A control unit configured to perform control so that travel control in the first state is prioritized when it is determined that the emergency vehicle is not approaching. Travel control in the second state is prioritized when it is determined that the emergency vehicle is approaching.
