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 skilled attention and increased risk of accidents.
Innovation Solution
An apparatus and method utilizing an image sensor, location information receiver, and controller to capture and process data for autonomous reverse driving, identifying restricted areas and determining a safe reverse path based on pre-stored movement traces and map information, allowing the vehicle to reverse autonomously while avoiding obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually controls reverse driving while monitoring multiple devices, then the driver can identify obstacles and control the vehicle, but the driving complexity and required attention increase significantly
Solution Approach 1:
The system enables autonomous reverse driving where the vehicle automatically navigates backward using its own sensors and processors. The controller autonomously monitors obstacles, determines the reverse path, and controls steering and acceleration without requiring continuous driver intervention, allowing the vehicle to serve itself during reverse maneuvers
Solution Approach 2:
The patent replaces manual mechanical control with an automated control system. The controller (processor) substitutes for the driver's manual steering and monitoring tasks by processing data from image sensors and other detectors to automatically control the vehicle's reverse movement, eliminating the need for direct mechanical driver input
2Reliability
If the driver manually monitors multiple devices during reverse driving, then obstacle identification is possible, but the risk of accidents increases due to divided attention
Solution Approach 1:
The system implements continuous feedback loops where image sensors and other detectors constantly monitor the environment during reverse driving. The controller processes this real-time data and adjusts the vehicle's path accordingly, providing ongoing feedback about obstacle detection and automatic path adjustment to ensure safe reverse maneuvers
Solution Approach 2:
The controller acts as an intermediary between the sensors and the vehicle's movement systems. It receives data from multiple sensors (image sensors, obstacle detectors), processes this information, and translates it into appropriate steering and acceleration commands, mediating the complex task of obstacle avoidance between detection and execution
3Extent of automation
If autonomous reverse driving is implemented using sensors and processors, then driving convenience is improved, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions within a single device: it processes image data from sensors, identifies obstacles, determines the reverse path, controls steering, and manages acceleration. This multi-functionality consolidates what would otherwise require separate systems into one universal control unit, reducing overall system complexity while maintaining high automation
Solution Approach 2:
The system performs preliminary actions by pre-storing map information and pre-processing sensor data before reverse driving begins. The controller prepares the reverse path planning and obstacle detection frameworks in advance, so that during actual reverse maneuvers, the system can execute pre-planned sequences rather than making all decisions in real-time, reducing computational complexity during operation

AI summary
An apparatus and a method for controlling a reverse driving are disclosed. 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; 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.
