Autonomous Driving Control Restoration via Override Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving devices may inadvertently restore autonomous driving control contrary to the occupant's intention after an override operation, leading to potential safety and operational issues.
Innovation Solution
The autonomous driving device includes an autonomous driving release unit, a travel plan setting unit, and an autonomous driving restore determination unit that assess operation parameters and travel plan differences to determine and restore autonomous driving control based on the occupant's intention, using a second travel plan generated after an override operation.

1Productivity
If autonomous driving control is automatically restored after an override operation, then the system returns to automated operation quickly, but the restoration may occur contrary to the occupant's intention
Solution Approach 1:
The system monitors operation parameters (steering angle, acceleration, braking) during and after the override operation to detect the occupant's driving intentions. This feedback mechanism allows the system to determine whether the occupant intends to resume manual driving or return to autonomous driving, thereby restoring control accurately according to the occupant's intention rather than automatically.
Solution Approach 2:
The system evaluates operation parameters in real-time during the override operation to predict the occupant's intention before restoration occurs. By analyzing the magnitude and duration of override operations, the system preliminarily determines whether restoration should proceed, preventing unintended automatic restoration while maintaining efficient return to autonomous driving when appropriate.
2Reliability
If the system monitors operation parameters to determine occupant intention, then restoration accuracy improves, but system complexity increases
Solution Approach 1:
The operation parameter monitoring system serves multiple functions: it detects override operations, evaluates occupant intentions, determines restoration appropriateness, and provides feedback for continuous improvement. By making the monitoring system multi-functional, the patent avoids adding separate dedicated systems for each function, thereby improving restoration accuracy without proportionally increasing system complexity.

AI summary
An autonomous driving device configured to release the autonomous driving control if an override operation is input during the execution of the autonomous driving control which is based on a first travel plan, set a second travel plan different from the first travel plan after the input of the override operation, determine whether or not to restore the autonomous driving control with the autonomous driving control which is based on the second travel plan after the input of the override operation, and maintain the manual driving and prohibit automatic starting of the autonomous driving control until after a predetermined time elapses after the autonomous driving control is released and when the determination is made not to restore the autonomous driving control.
