Solution Overview
Problem
Autonomous driving systems face challenges in safely transitioning from autonomous to manual mode during emergency avoidance and braking scenarios, particularly due to unintentional user inputs caused by high kinetic energy, which can lead to accidents.
Innovation Solution
An apparatus and method that utilize a sensor device to assess collision risks, a user input sensing device to detect control inputs, and a processor to determine when to switch from autonomous to manual mode, ensuring safety by maintaining autonomous control during emergency maneuvers and only switching to manual mode when the risk is mitigated or a user intentionally takes control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous driving system allows switching to manual mode during emergency avoidance control and emergency braking control, then the user can take control of the vehicle, but unintentional user inputs due to high kinetic energy may cause accidents
Solution Approach 1:
The system performs preliminary assessment of user input intent before allowing mode switching. The processor analyzes whether the user input is intentional or unintentional by evaluating the driving situation, kinetic energy level, and input characteristics in advance of the mode transition, preventing accidental switching during high-risk emergency maneuvers
Solution Approach 2:
The system implements feedback mechanisms where the processor continuously monitors user inputs, driving conditions, and system state. This feedback loop enables the system to distinguish between intentional user commands and unintentional inputs caused by emergency vehicle movements, dynamically controlling whether mode switching is permitted based on real-time assessment
2Reliability
If the autonomous driving system maintains autonomous control during emergency maneuvers, then safety is improved by preventing unintentional user inputs, but the user cannot respond to unexpected situations
Solution Approach 1:
The system dynamically adjusts the autonomous driving mode based on real-time driving conditions. During emergency avoidance control and emergency braking control, the system maintains autonomous mode to prevent unintentional inputs. However, when emergency conditions are resolved or when user input is determined to be intentional, the system allows switching to manual mode, creating a flexible, adaptive control system that responds to changing situations
3Ease of operation
If the system switches to manual mode immediately upon user input during autonomous driving, then user intent is respected, but risky events may occur due to high kinetic energy from emergency maneuvers
Solution Approach 1:
The system applies preliminary anti-action by preventing the harmful effect of unintentional user inputs before they can occur. During emergency avoidance control and emergency braking control, the processor blocks mode switching requests that are determined to be unintentional, countering the potential harm of accidental manual activation during high kinetic energy states before the switching can cause safety issues

AI summary
An apparatus for controlling autonomous driving and a method for the same are provided. The apparatus includes a sensor device provided in a vehicle to acquire information on a collision risk during autonomous driving of the vehicle, a user input sensing device to sense a control input, which is input from a user of the vehicle, for switching an autonomous driving mode, and a processor to determine a collision risk, based on the information acquired through the sensor device, to determine whether to switch the autonomous driving mode, based on the control input of the user, when the collision risk is determined as being present, and to control autonomous driving of the vehicle, based on a determination result of whether to switch the autonomous driving mode.
