Vehicle Sensor Wash Button Display Based on Dirt Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems always display a touch panel switch for camera washing when the vehicle is in a rearward drive state, leading to unnecessary annoyance for users as the switch is displayed even when the camera is only slightly dirty.
Innovation Solution
A display control device that receives information on the dirtiness of vehicle-mounted sensors and controls the display of a wash execution button on a vehicle display device, ensuring it is only displayed when necessary based on the dirt status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel switch for camera washing is always displayed when the vehicle is in a rearward drive state, then the user can easily access the washing function, but the user feels annoyed when the camera is only slightly dirty and does not require washing
Solution Approach 1:
The system changes the display parameter of the wash execution button based on the dirtiness parameter of the sensor. When the sensor is detected to be dirty (meets predetermined condition), the button is displayed; when clean, it is hidden. This dynamic parameter adjustment resolves the contradiction by making the button accessible when needed but invisible when not needed, eliminating user annoyance while preserving ease of operation.
Solution Approach 2:
The system implements feedback by detecting the dirtiness state of the sensor and using this information to control the display state of the wash execution button. The detection unit provides feedback about sensor condition to the control unit, which then adjusts the UI accordingly. This feedback mechanism ensures the button is only displayed when washing is actually required, resolving the contradiction between accessibility and user annoyance.
2Object-affected harmful factors
If the wash execution button is displayed only when the sensor is detected to be dirty, then user annoyance is reduced, but the system complexity increases due to dirt detection requirements
Solution Approach 1:
The sensor system performs self-detection of its own dirtiness state. The detection unit monitors the sensor condition automatically without requiring external inspection or manual input from the user. This self-service approach allows the system to determine when washing is needed using existing sensor capabilities, reducing the need for additional complex detection hardware while still achieving the goal of reducing user annoyance.

AI summary
A display control device installed in a vehicle includes a receiving unit that receives information concerning dirt of a vehicle-mounted sensor installed in the vehicle, and a control unit that controls display of a wash execution button displayed on a display device installed in the vehicle for executing washing of the vehicle-mounted sensor, based on the information concerning the dirt received by the receiving unit.
