Vehicle Display Control for Blocking Unintended Driver Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display systems risk unintended operations when new proposals or instructions are displayed to drivers while they are already operating the vehicle, leading to potential erroneous reflections of operations.
Innovation Solution
A display control device that receives proposal information and temporarily changes the display from a usual image to a proposal image, prohibiting the reflection of operation signals in instructions during a predetermined time period to prevent erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If new proposal information is displayed to the driver during vehicle operation, then the driver receives necessary instructions, but the driver may perform unintended operations on the new proposal
Solution Approach 1:
The system performs preliminary action by displaying proposal information in a non-operable state first, allowing the driver to read and understand the proposal before enabling operations. The control section displays the proposal image and maintains it in a state where operations are not reflected, then after a predetermined time period, transitions to allowing operations. This ensures the driver has time to process the information before being able to act on it, preventing unintended operations.
2Speed
If the driver is allowed to operate immediately when new proposal is displayed, then operation responsiveness is improved, but erroneous operations occur
Solution Approach 1:
The system implements a predetermined time period delay between displaying the proposal and enabling operations. During this period, the proposal is displayed but operations are not reflected. This timing mechanism balances responsiveness by eventually allowing quick operation while preventing immediate erroneous operations during the transition phase.
3Ease of operation
If the display continuously shows operational options, then the interface remains responsive, but the driver may accidentally select wrong options
Solution Approach 1:
The system displays the proposal image in a preliminary non-operable state, showing the interface elements but preventing their selection. After the predetermined time period elapses, the system transitions to an operable state where selections are reflected. This approach maintains interface responsiveness by keeping all elements visible while temporarily preventing harmful selections.
Solution Approach 2:
The control section implements preliminary anti-action by blocking operation signals during the predetermined time period. Even when the driver attempts to operate the interface, the control section prevents these signals from being reflected in the instruction execution. This counter-measure specifically addresses the harmful effect of potential erroneous operations during the transition phase.

AI summary
A display control device includes a processor. The processor being configured to: receive proposal information relating to a proposal that requests an instruction from a vehicle occupant of a vehicle; receive an operation signal that is outputted in accordance with an operation of the vehicle occupant; and in a case of receiving the proposal information, change display of a display device provided within the vehicle from a usual image to an image that includes a proposal image relating to the proposal, and, during a predetermined time period from start of display of the proposal image, prohibit reflection of the operation signal in the instruction.
