Driving Authority Transfer with Brake and Steering Status Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated valet parking systems face liability issues due to traffic accidents caused by abnormal states of the vehicle's braking and steering systems during authority transfer, necessitating a method to check the status of these systems before transferring driving authority.
Innovation Solution
A vehicle driving authority transfer method that checks the status of the braking and steering systems before transferring authority, ensuring normal operation to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If driving authority is transferred to the automated valet parking system, then automation level and convenience are improved, but liability disputes and safety risks increase due to potential system abnormalities
Solution Approach 1:
The patent implements a preliminary status check mechanism that detects the normality of the braking system and steering system before driving authority is transferred. This preliminary action ensures that the automated driving system only operates when critical systems are functioning properly, thereby maintaining high automation levels while preventing reliability issues from causing liability disputes.
2Ease of operation
If driving authority is transferred without system status check, then transfer process is simplified and faster, but traffic accidents may occur due to abnormal braking or steering systems
Solution Approach 1:
The patent introduces a preliminary status check step that detects whether the braking system and steering system are normal before completing the authority transfer. This preliminary detection maintains operational simplicity by automating the check process while effectively eliminating traffic accident risks caused by abnormal systems.
3Reliability
If system status check is implemented before authority transfer, then safety and reliability are improved, but transfer process complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the automated driving system automatically detects and evaluates the status of its own braking and steering systems before authority transfer. This self-detection approach improves safety without significantly increasing external system complexity, as the system uses its existing sensors and control units to perform the status check.
4Object-affected harmful factors
If comprehensive system checks are performed before authority transfer, then accident prevention capability is improved, but time consumption and operational efficiency decrease
Solution Approach 1:
The patent extracts and focuses detection efforts on only the critical systems most likely to cause accidents - specifically the braking system and steering system. By selectively checking only these essential components rather than performing comprehensive checks on all vehicle systems, the patent achieves effective accident prevention while minimizing time consumption during the authority transfer process.

AI summary
A vehicle driving authority transfer method and apparatus are described for assisted driving and automated driving. The method includes checking a status of a system of a vehicle before a driving authority of the vehicle is transferred. The driving authority of the vehicle is transferred only when the vehicle is at a normal status. Therefore, the status of the system of the vehicle is checked before transferring the driving authority of the intelligent vehicle, thereby avoiding a liability dispute arising from a traffic accident caused by abnormality of the status of the system of the vehicle, especially by abnormality of a braking system and/or a steering system closely related to vehicle operability/manipulability, after the driving authority of the vehicle is transferred.
