Lane Change Assistance Feedback for Difficult Merge Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to reflect the intentions of occupants regarding lane change attempts during difficult driving conditions, leading to inefficiencies and occupant discomfort.
Innovation Solution
A vehicle control device that includes a lane change request reception unit, surroundings information acquisition, viability determination, and display instruction units to ask occupants whether to continue or cancel lane change requests, allowing the system to adapt to the occupant's intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system continuously attempts lane change by driving assistance when conditions are difficult, then the lane change may eventually succeed, but occupant fatigue increases and energy consumption rises due to unnecessary operations
Solution Approach 1:
The system displays a message to the occupant when lane change conditions are difficult, seeking feedback on whether to continue attempting lane change. Based on the occupant's response (continue or cancel), the system adjusts its behavior accordingly, thereby reducing unnecessary operations that cause fatigue while maintaining reliable lane change execution when appropriate
2Adaptability or versatility
If the system asks the occupant whether to continue lane change request when lane change is difficult, then occupant intentions are reflected, but the system complexity increases due to additional communication and control logic
Solution Approach 1:
The system applies partial action by selectively displaying messages only when lane change conditions are determined to be difficult, rather than continuously communicating with the occupant. This conditional approach reflects occupant intentions in critical situations while avoiding excessive communication that would increase system complexity
3Ease of operation
If the system displays messages asking to continue lane change when conditions are difficult, then occupant control is improved, but the loss of time occurs due to additional interaction steps
Solution Approach 1:
The system performs preliminary action by determining lane change viability conditions in advance and only displaying messages when conditions are actually difficult. This pre-established decision logic enables quick response to occupants while avoiding unnecessary time-consuming interactions in normal conditions, thus improving occupant control without significant time loss

AI summary
A vehicle control device that is installed at a vehicle configured to perform lane change assistance and that comprises a processor, wherein the processor is configured to: receive a request for a lane change by lane change assistance from an occupant of the vehicle; acquire surroundings information of the vehicle; when the request for a lane change has been received, determine whether or not the lane change by lane change assistance is viable based on the acquired surroundings information; and display a message, asking whether or not the request for a lane change by lane change assistance is to be continued, on a display section provided in a cabin of the vehicle in cases in which the lane change by lane change assistance has been determined to be difficult.
