Automated Driving Control to Avoid Parallel Travel Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During automated driving without monitoring obligation, the continuation of a parallel traveling state between vehicles can lead to a decrease in convenience for the driver as occupants of adjacent vehicles may see the driver performing secondary tasks, compromising the driver's comfort.
Innovation Solution
A vehicle control device and method that includes a traveling environment specifying unit and a parallel-traveling avoiding unit to execute control strategies that prevent the subject vehicle from entering a parallel traveling state with adjacent vehicles, thereby maintaining driver convenience by ensuring the driver's tasks are not visible to occupants of adjacent vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated driving without monitoring obligation is implemented, then driver convenience is improved by allowing secondary tasks, but driver privacy deteriorates as occupants of adjacent vehicles can see the driver performing tasks
Solution Approach 1:
The system performs preliminary detection of adjacent vehicles and proactively executes parallel-traveling avoiding control before the driver engages in secondary tasks that could be observed, thereby preventing privacy exposure while maintaining the ability to perform convenience-enhancing activities
Solution Approach 2:
The control system acts as an intermediary between the driver's need for convenience and the privacy concern, automatically adjusting vehicle trajectory to maintain safe distance from adjacent vehicles, thus mediating the conflict without requiring driver intervention
2Loss of energy
If parallel traveling state is maintained, then fuel efficiency is improved by reducing frequent lane changes, but driver comfort deteriorates due to visibility of driver tasks by adjacent vehicle occupants
Solution Approach 1:
The system detects adjacent vehicles in advance and proactively adjusts lane position or executes lane changes before the parallel traveling state is established, preventing the privacy issue while minimizing unnecessary maneuvers to maintain fuel efficiency
Solution Approach 2:
The control system dynamically adjusts the vehicle's lateral position and lane selection based on real-time detection of adjacent vehicles, transitioning between maintaining parallel travel and executing lane changes according to privacy requirements and fuel efficiency considerations

AI summary
A technique for a vehicle configured to execute automated driving without monitoring obligation is described. A traveling environment of the vehicle is specified. Parallel-traveling avoiding control is executed based on the traveling environment specified by the traveling environment specifying unit during the automated driving without monitoring obligation. The parallel-traveling avoiding control is travel control of the vehicle to avoid a parallel traveling state in which the vehicle and an adjacent vehicle traveling in an adjacent lane adjacent to a traveling lane of the vehicle travel in parallel.
