Narrow-Road Vehicle Control for Oncoming-Passage Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving technologies struggle to navigate narrow roads and alleys safely, especially when faced with obstacles or parked vehicles, and inexperienced drivers often cause accidents due to insufficient judgment on vehicle widths.
Innovation Solution
A vehicle driving system equipped with sensors to monitor the environment, a controller to recognize oncoming objects, determine priority based on road width comparisons, and control vehicle travel to ensure safe passage for the object, even in congested conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving technology is implemented on narrow roads without sufficient peripheral space, then the system cannot safely navigate, but manual manipulation is required which inexperienced drivers cannot perform safely
Solution Approach 1:
The patent introduces an intermediary system between the driver and the vehicle controls. This system uses sensors to detect the narrow road environment and automatically adjusts vehicle parameters (steering angle, speed, acceleration) without requiring direct driver intervention, thus resolving the contradiction between automation and safety in narrow roads
Solution Approach 2:
The system performs preliminary detection of the road environment using sensors before the vehicle enters the narrow road section. It pre-calculates the optimal driving path and parameters, enabling the vehicle to automatically navigate the narrow road safely before the driver can react, thus improving both automation extent and reliability
2Ease of operation
If the vehicle width is not accurately judged by inexperienced drivers, then collisions occur with obstacles, but providing manual control does not solve the judgment problem
Solution Approach 1:
The vehicle's autonomous system performs the width judgment function that inexperienced drivers cannot do properly. The sensors and control system work together to automatically assess the vehicle's position relative to obstacles and adjust the driving path, making the system self-sufficient for width judgment without relying on driver skill
Solution Approach 2:
The patent replaces the driver's manual width judgment and steering control with an automated sensor-based system. The sensors detect obstacle positions and the control system calculates the appropriate steering adjustments, substituting the mechanical driver action with an automated electronic control system that accurately judges vehicle width and position
3Productivity
If the vehicle maintains high speed in narrow alleys with obstacles, then productivity is high, but the risk of collision with oncoming vehicles increases
Solution Approach 1:
The patent implements dynamic speed adjustment based on real-time detection of oncoming vehicles. When an oncoming vehicle is detected in a narrow alley, the system automatically reduces speed to a safe level. When the alley is clear, the vehicle can maintain higher speed, thus dynamically optimizing both productivity and safety based on the current traffic situation

AI summary
A vehicle driving system enabling safe traveling on a narrow road and a method performed by the vehicle driving system for controlling a vehicle are disclosed. The vehicle driving system includes a sensor configured to monitor an environment outside a vehicle and a controller. The controller is configured to recognize an oncoming traveling object through the sensor, derive a width of a travelable road between the traveling object and the vehicle, determine priority between the traveling object and the vehicle when the width of the travelable road is smaller than a sum of widths of the traveling object and the vehicle, and, when the traveling object is determined to have the priority, control traveling of the vehicle to provide a space in a lateral direction of the vehicle to allow the traveling object to pass.
