Vehicle Display Interface for Autonomous Lane Change Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle occupants feel unsafe during autonomous lane changes because they are not aware of the conditions of the destination lane, including the presence of other vehicles, which can lead to uncertainty about the lane change process.
Innovation Solution
A display device for vehicles that includes a control section and a display section, which displays lane information and confirmation displays before a lane change, showing the acquisition of vicinity information, goal position confirmation, and lane change feasibility, ensuring the occupant is informed about the lane change process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If autonomous lane change is conducted without displaying confirmation information, then lane change execution speed is improved, but vehicle occupant safety perception deteriorates
Solution Approach 1:
The system displays confirmation information about destination lane conditions (presence of other vehicles, lane availability) before executing the lane change. This preliminary display action allows the occupant to verify safety conditions in advance, improving safety perception without delaying the actual lane change execution.
Solution Approach 2:
The system provides visual feedback to the occupant by displaying confirmation information regarding the destination lane conditions. This feedback mechanism allows the occupant to understand what the autonomous driving system perceives, thereby improving safety perception while maintaining automated execution speed.
2Reliability
If detailed lane condition information is displayed, then occupant safety perception is improved, but device complexity increases
Solution Approach 1:
The system extracts and displays only the essential confirmation information needed for occupant safety perception, such as the presence of other vehicles in the destination lane and lane availability. By selecting only critical information rather than displaying all possible data, the system improves safety perception without unnecessarily increasing display complexity.
Solution Approach 2:
The system displays confirmation information in a localized and focused manner on the display unit, presenting key safety-related details (other vehicle presence, lane conditions) in a concentrated format rather than dispersing information throughout the interface, thereby improving clarity without increasing overall system complexity.
3Reliability
If confirmation display is shown regardless of other vehicle presence, then occupant safety perception is consistently improved, but information loss occurs when lane is clear
Solution Approach 1:
The system dynamically adjusts the confirmation display based on the detected lane conditions. When other vehicles are present in the destination lane, the system displays confirmation information to enhance safety perception. When the lane is clear, the system omits or modifies the display, preventing information loss and maintaining context accuracy while still providing safety confirmation when needed.

AI summary
A display device includes a display section provided in a cabin of a vehicle that is capable of autonomous driving, memory, and a processor connected to the memory. The processor is configured to, before conducting a lane change by autonomous driving from a first lane in which the vehicle is running to a second lane that is distinct from the first lane, display a lane display and a confirmation display at the display section. The lane display corresponds to the first lane and the second lane. The confirmation display relates to confirmation of a condition of the second lane.
