Travel Controller Potential Field Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control technologies do not adequately address the psychological discomfort experienced by drivers due to peripheral vehicles, particularly when large vehicles travel adjacent to the host vehicle, as they do not consider the psychological impact in adjusting the travel position of the host vehicle.
Innovation Solution
A travel control system that includes a vehicle detection device, a potential field generation device, and a control device to assign and manage potential fields indicating psychological pressure, allowing the host vehicle to avoid high-pressure areas, thereby reducing driver discomfort through adjustments in speed and lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous control maintains proper vehicle-to-vehicle distance, then safety is improved, but driver psychological discomfort increases due to peripheral vehicles traveling adjacent to the host vehicle
Solution Approach 1:
The system dynamically changes the vehicle-to-vehicle distance parameter based on the type of peripheral vehicle detected. When a large vehicle is detected in the adjacent lane, the host vehicle increases its distance from the peripheral vehicle, transforming the fixed safety distance into a variable parameter that adapts to different situations, thereby reducing driver psychological discomfort while maintaining safety
Solution Approach 2:
The system implements feedback by continuously monitoring the presence and type of peripheral vehicles, and adjusting the host vehicle's travel position accordingly. The travel position adjustment amount is determined based on feedback from the vehicle type determination device, creating a closed-loop control system that responds to environmental conditions
2Device complexity
If the host vehicle maintains a fixed travel position, then control simplicity is improved, but driver psychological discomfort increases when large vehicles travel adjacent to the host vehicle
Solution Approach 1:
The system transitions from static travel position control to dynamic travel position control. The travel position adjustment amount varies dynamically based on the type of peripheral vehicle detected, allowing the host vehicle to adapt its position in real-time. This dynamic adjustment reduces driver psychological discomfort when large vehicles are present while maintaining operational simplicity through automated control

AI summary
A travel control device includes: a vehicle detection device configured to detect a position of a peripheral vehicle that travels in a periphery of a host vehicle in a lane, in which the host vehicle travels, or a lane adjacent to and heading in a same direction of the host vehicle; a generation device configured to assign a potential field to a predetermined region, which is adjacent to the position of the peripheral vehicle, the potential field indicating a degree of psychological pressure received by a driver of the host vehicle, and configured to generate a potential distribution that represents a distribution of the potential field of the peripheral vehicle on a road; and a control device configured to control a travel condition of the host vehicle that the host vehicle travels in the potential field relatively low in the potential distribution.
