Lane Change Return Control With Predicted Timing Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to provide a sense of security to occupants when a condition to start a second lane change control is not satisfied for a specific period of time after a first lane change, leading to occupant anxiety.
Innovation Solution
A vehicle control device and method that includes displaying a first image expressing information related to the start of the second lane change control prior to its execution, along with displaying a predicted time until the control becomes executable, and providing images for interrupt conditions, thereby enhancing occupant awareness and reducing anxiety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control system waits for the second lane change control to become executable before providing information to the occupant, then the information provided is accurate and reliable, but the occupant experiences anxiety and loss of security during the waiting period
Solution Approach 1:
The system performs preliminary action by displaying information about the second lane change control before it becomes executable. Specifically, it shows that the control is being prepared and provides an estimated time until execution, allowing the occupant to understand the system's status and reduce anxiety without compromising the reliability of the actual control execution.
Solution Approach 2:
The system implements feedback by continuously providing the occupant with status information about the second lane change control. This includes displaying whether the control is executable and providing estimated time information, creating a feedback loop that keeps the occupant informed about the system's state and reduces uncertainty.
2Object-affected harmful factors
If the system displays information about the second lane change control too early, then the occupant's anxiety is reduced, but the information may be misleading or cause vexation if the control does not execute as expected
Solution Approach 1:
The system applies partial action by providing limited information about the second lane change control - specifically showing that it is being prepared and providing estimated time - without over-promising execution. This partial information provision reduces anxiety while maintaining reliability by not making definitive claims about execution timing that could prove misleading.
3Device complexity
If no information is provided about the second lane change control status, then the system maintains simplicity and avoids potential misinformation, but the occupant experiences prolonged anxiety and feels lack of security
Solution Approach 1:
The system extracts and displays only the essential information about the second lane change control status - specifically whether it is executable and estimated time information - without providing excessive detail. This selective information extraction reduces occupant anxiety while maintaining system simplicity and avoiding information overload.

AI summary
A vehicle control device including a processor that, after a first lane change control has been executed on a vehicle traveling in a cruising lane to move the vehicle to a target lane, is configured to execute a second lane change control on the vehicle to return the vehicle from the target lane to the cruising lane, and a display device that is configured to display a first image expressing information related to a start of the second lane change control prior to the second lane change control being executed on the vehicle traveling in the target lane.
