Vehicle-Wide Display Layout for Adaptive Driver-Passenger Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in vehicles do not adequately adapt to varying driving states and passenger configurations, leading to suboptimal operability and potential safety issues during manual and automatic driving modes.
Innovation Solution
A display device with a display unit extending from the driver's seat to the passenger seat, featuring an operation unit and a control unit that adjusts the display and operation areas based on the vehicle's driving state and steering operation unit position, ensuring appropriate arrangement and preventing erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display unit extends from the driver's seat to the occupant seat to provide a large display area, then the display capability is improved, but the operability deteriorates due to difficulty in determining the appropriate operation area during different driving states
Solution Approach 1:
The operation area is dynamically adjusted based on the driving state (manual or automatic) and steering wheel position. During automatic driving with the steering wheel in the home position, the operation area expands to include the entire display unit. During manual driving or when the steering wheel is displaced, the operation area is restricted to prevent interference with steering operations, thus resolving the contradiction between large display area and ease of operation.
2Ease of operation
If the operation area is expanded to cover the entire display unit for improved accessibility, then the ease of operation is improved, but the reliability deteriorates due to potential erroneous operations during manual driving
Solution Approach 1:
The system continuously monitors the driving state (manual or automatic) and steering wheel position to dynamically adjust the operation area. This feedback mechanism ensures that the operation area is restricted when steering operations are needed, preventing erroneous inputs while maintaining full accessibility during automatic driving, thus resolving the contradiction between ease of operation and reliability.
3Device complexity
If the display device provides fixed display and operation areas regardless of driving state, then the device complexity is reduced, but the adaptability deteriorates due to inability to respond to different driving conditions
Solution Approach 1:
The operation area is dynamically adjusted based on the driving state (manual or automatic) and steering wheel position. During automatic driving with the steering wheel in the home position, the operation area expands to include the entire display unit. During manual driving or when the steering wheel is displaced, the operation area is restricted to prevent interference with steering operations, thus resolving the contradiction between large display area and ease of operation.

AI summary
A display device mounted on a vehicle, including: a display unit, wherein the vehicle has a driver's seat for a driver who drives the vehicle to sit and an occupant seat for a passenger of the vehicle to sit, the driver's seat and the occupant seat being arranged side by side, and the display unit is provided extending from the driver's seat to the occupant seat; an operation unit that receives an operation onto an operation area provided on the display unit; a display control unit that causes content to appear on a display area of the display unit; and a control unit that adjusts at least one of the operation area and the display area on the display unit depending on a driving state of the vehicle and a use state of a steering operation unit of the vehicle.
