Vehicle Control Method for Autonomous Driving Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to allow passengers to take control of a vehicle that is autonomously driving, especially in emergency situations, and to determine the order of priority among multiple passengers for handing over control, while also considering factors like driver's license, sobriety, and consent.
Innovation Solution
A vehicle control method that determines if control needs to be handed over to a passenger, selects a passenger based on priority, and adjusts the seating and display environment to facilitate passenger control, including steering, acceleration, and braking, using sensors and external commands to ensure safe handover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving control is implemented, then driving safety and convenience are improved, but the ability to respond to emergency situations and sensor failures is worsened
Solution Approach 1:
The system pre-identifies qualified passengers who are capable of taking over driving control before emergencies occur. Passenger information including driving license status, sobriety levels, and consent preferences are collected and stored in advance, enabling rapid handover decision-making when sensor failures or emergencies occur without requiring real-time assessment
Solution Approach 2:
The vehicle control device acts as an intermediary between the autonomous driving system and passengers. It monitors sensor status, detects failures, and manages the handover process to qualified passengers, bridging the gap between automated control and human intervention capabilities
2Adaptability or versatility
If control handover to passengers is enabled, then emergency response capability is improved, but system complexity increases
Solution Approach 1:
The system evaluates passengers based on multiple parameters including driving license status, sobriety level, consent preference, and seating position. By changing and comparing these parameters against predefined thresholds and requirements, the system automatically determines qualified passengers without complex manual assessment procedures
Solution Approach 2:
Passengers pre-register their consent to receive driving control handover requests and provide their driving capability information in advance. This self-service approach reduces the system's burden of real-time assessment and enables automatic identification of qualified passengers when handover is needed
3Productivity
If multiple passenger priorities are established, then control handover efficiency is improved, but difficulty of detecting and measuring qualified passengers increases
Solution Approach 1:
The system performs preliminary assessment of passenger qualifications before handover situations occur. Passenger information including driving license status, sobriety, and consent preferences are collected and stored in advance, creating a ready-to-use database that enables rapid identification of the most suitable passenger when handover is needed
Solution Approach 2:
Different seating positions within the vehicle are assigned different priority levels for receiving driving control. The system evaluates passenger qualifications locally based on their specific seating position and the handover situation, rather than applying a single uniform assessment criterion to all passengers

AI summary
A vehicle control method is disclosed. The vehicle control method includes: while controlling the driving of a vehicle taking control of itself, determining if there is a need to hand over the control of driving to a passenger in the vehicle; if it is determined that there is a need to hand over the control of driving to a passenger in the vehicle, selecting at least one of passengers to whom the control of driving may be handed over; determining an order of priority in handing over the control of driving by taking into consideration the at least one selected passenger's occupancy state information; handing over the control of driving to a top priority passenger according to the order of priority; and controlling the driving environment by taking into consideration the top priority passenger's occupancy state information.
