Cooperative Autonomous Driving Control via Driver State Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems and autonomous driving technologies face limitations in ensuring driver safety and convenience, particularly when drivers are drowsy or incapacitated, and are prone to errors due to varying road and weather conditions.
Innovation Solution
A cooperative autonomous driving apparatus and method that dynamically allocates driving control based on driver state and environmental factors, using a driver state determination unit, autonomous driving control unit, and driving control determination unit to switch between manual, cooperative, and autonomous driving modes, and updates section characteristics in a database based on risk indices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If driver assistance systems are used to assist drivers with longitudinal or lateral control, then driving convenience is improved, but the system cannot assist when the driver is drowsy or incapacitated
Solution Approach 1:
The system monitors driver state parameters (attention level, drowsiness indicators) and dynamically changes the operational mode of the driving assistance system based on these parameter changes, transitioning from manual assistance mode to autonomous driving mode when driver incapacity is detected
Solution Approach 2:
A driver state monitoring unit acts as an intermediary between the driver and the autonomous driving control unit, detecting driver state and mediating the transition of control authority based on the driver's capability level
2Reliability
If autonomous driving control is implemented, then driver safety is improved, but sensor recognition and determination errors may occur depending on driving environment
Solution Approach 1:
The system dynamically adjusts the level of autonomous driving control and monitoring based on real-time assessment of environmental conditions and sensor reliability, rather than operating in a fixed autonomous mode
Solution Approach 2:
The system continuously monitors driving environment conditions and sensor performance, using this feedback to adjust control strategies and maintain safety despite varying sensor recognition accuracy in different environments
3Ease of operation
If conventional driver assistance systems are used, then longitudinal or lateral control is assisted, but the system complexity increases requiring preparation for driver intervention
Solution Approach 1:
The autonomous driving control unit is designed to perform multiple functions including longitudinal control, lateral control, and driver state monitoring, replacing the need for separate assistance systems and reducing overall system complexity

AI summary
The present invention relates to an apparatus and method for performing cooperative autonomous driving between a vehicle and a driver. For this, a cooperative autonomous driving apparatus according to the present invention includes a driver state determination unit for determining a state of a driver and calculating the state of the driver as a risk index. An autonomous driving control unit classifies section characteristics of respective sections included in a path to a destination corresponding to the driver based on section data stored in a database (DB), and controls autonomous driving of a vehicle in which the driver is riding, based on a driving environment recognized for the path to the destination corresponding to the driver. A driving control determination unit determines driving modes of the respective sections included in the path based on the state of the driver and the section characteristics.
