Vehicle Display Privacy Modes for Driving Diagnosis Results
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to effectively conceal driving diagnosis information from occupants other than the specific intended recipient, as they do not provide a mode to obscure the visual recognition of such information.
Innovation Solution
A vehicle display device with a mode setting unit that switches between a first mode for clear display of driving diagnosis results and a second mode where the display is made more difficult to recognize, using lower brightness and saturation, and potentially omitting characters, to prevent other occupants from understanding the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If driving diagnosis information is displayed clearly for the specific occupant, then the specific occupant can understand the information, but other occupants can also recognize the information
Solution Approach 1:
The display device dynamically changes display parameters (brightness, saturation, character presence) based on the detected mode, allowing the same display to serve different functions under different conditions. This resolves the contradiction by making the information accessible to the specific occupant in the first mode while preventing recognition by others in the second mode.
Solution Approach 2:
The patent changes physical display parameters (brightness, saturation, character inclusion) to control information recognizability. By adjusting these parameters based on the mode, the system achieves both information accessibility for the intended recipient and confidentiality from others simultaneously.
2Loss of information
If the display is made more difficult to recognize to prevent other occupants from knowing the information, then information confidentiality is improved, but the specific occupant may also have difficulty recognizing it
Solution Approach 1:
The system uses dynamic mode switching to adjust display characteristics. In the first mode, displays are optimized for recognizability; in the second mode, they are optimized for confidentiality. This temporal separation allows both requirements to be satisfied under different operating conditions.
Solution Approach 2:
By changing display parameters (brightness, saturation, character presence) based on the mode, the system achieves different levels of information accessibility. The specific occupant can understand the information when needed, while other occupants cannot recognize it when privacy is required.

AI summary
A vehicle display device includes: a mode setting unit provided in a vehicle for setting a mode of the vehicle to one of a first mode and a second mode; an acquisition unit provided in the vehicle for acquiring a driving diagnosis result of the vehicle; and a display unit that can display an image representing the driving diagnosis result in a first manner when the vehicle is in the first mode, and that can display the image representing the driving diagnosis result in a second manner that is more difficult for an occupant of the vehicle to recognize than in the first manner when the vehicle is in the second mode.
