Autonomous Reverse Path Control Using Forward Trace Replay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face difficulty in reverse driving due to the need to control the steering wheel while identifying multiple devices like rearview mirrors and cameras to avoid obstacles, especially in restricted areas like dead ends or one-way streets, requiring special skills and attention.
Innovation Solution
An apparatus and method utilizing an image sensor, location information receiver, and controller to capture and process data, identifying restricted areas and determining a reverse driving path based on pre-stored movement traces, allowing autonomous reverse driving while avoiding obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver manually controls reverse driving while monitoring multiple devices, then the driver can avoid obstacles, but the driving operation becomes complex and difficult
Solution Approach 1:
The system enables autonomous reverse driving where the vehicle automatically controls itself to reverse along the forward path using stored movement trace data, eliminating the need for the driver to manually coordinate steering and monitor multiple devices
Solution Approach 2:
The system pre-stores the forward movement trace data before reverse driving is needed, allowing the vehicle to automatically replay this trajectory in reverse without real-time driver intervention for path planning
2Measurement precision
If the driver focuses attention on monitoring devices during reverse driving, then obstacle detection improves, but the driver requires special skills and increased attention
Solution Approach 1:
The system replaces the driver's manual monitoring and control operations with automated image recognition and control systems that process camera feeds and execute reverse maneuvers without requiring driver expertise in coordinate mapping and trajectory calculation
3Ease of operation
If autonomous reverse driving is implemented, then driving convenience improves, but the system complexity increases
Solution Approach 1:
The system uses the existing forward movement trace storage mechanism for dual purposes: storing forward trajectory data and enabling autonomous reverse driving, avoiding the need for separate dedicated reverse driving hardware systems

AI summary
Disclosed are an apparatus and a method for controlling a reverse driving. The apparatus includes: a movement trace storage unit configured to detect and store the movement trace of the vehicle moving forward; a restricted driving area identifier configured to identify a restricted driving area, based on at least one of the processing result of the image data, the location information, and pre-stored map information; a reverse driving path determiner configured to identify whether a reverse driving request signal is received when the restricted driving area is identified, generate one or more driving paths, based on, the stored movement trace when the reverse driving request signal is received, and determine the reverse driving path, based on the one or more driving paths; and a movement controller configured to control movement of the vehicle to reverse the vehicle along the reverse driving path. The present disclosure has an effect of providing driving convenience by controlling a reverse driving when a vehicle enters a dead end or a one-way street by mistake.
