Vehicle Screen Content Switching to Prevent Driver Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems do not effectively manage the display content on a screen shared by a driver and a front passenger, often leading to distractions for the driver due to dynamic or private content intended for the passenger.
Innovation Solution
A method and system that analyze the display elements on a vehicle screen to determine if they are dynamic or private, replacing them with static alternatives from the driver's perspective while maintaining the original content for the front passenger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single screen is used for both driver and front passenger, then device complexity is reduced, but the driver may be distracted by dynamic or private content intended for the passenger
Solution Approach 1:
The patent applies local quality by displaying different content on different regions of the same screen. The display device shows passenger-oriented dynamic content in a first display region and driver-oriented static content in a second display region, allowing each user to see appropriate content without distraction while using a single screen device.
Solution Approach 2:
The patent segments the display content into different types (dynamic/passenger-oriented and static/driver-oriented) and displays them in separate regions. This segmentation allows the system to provide personalized content to each user while maintaining a unified screen device, resolving the contradiction between device simplicity and distraction prevention.
2Ease of operation
If dynamic display content is shown to both driver and passenger, then ease of operation is improved, but driver safety is compromised due to distraction
Solution Approach 1:
The system automatically provides different quality of display content to different users based on their role. Passenger-oriented dynamic content is displayed in the first region while driver-oriented static content is displayed in the second region, eliminating the need for manual content management while ensuring driver safety.
Solution Approach 2:
The display device automatically determines what content to show each user based on their position and the nature of the content. The system self-adjusts the display content without requiring driver intervention, providing ease of operation while maintaining safety by automatically preventing distracting content from reaching the driver.
3Object-affected harmful factors
If separate screens are provided for driver and passenger, then driver distraction is eliminated, but device complexity and cost increase
Solution Approach 1:
The patent merges the functionality of separate driver and passenger display devices into a single display device. By using one screen with multiple display regions that show different content simultaneously, the system achieves the safety benefits of separate displays while reducing device complexity and cost through consolidation.
Solution Approach 2:
The single display device performs multiple functions by displaying different content for different users simultaneously. It serves both as a passenger entertainment device and a driver information display, eliminating the need for separate devices while maintaining all necessary functions.
4Loss of information
If all display content is visible to both users, then information sharing is improved, but passenger privacy is compromised
Solution Approach 1:
The system applies local quality by displaying different information in different regions of the screen. Passenger-oriented content including private information is displayed in the first display region visible to the passenger, while driver-oriented content is displayed in the second region, ensuring information is shared appropriately without compromising privacy.
Solution Approach 2:
The display content is segmented into passenger-oriented and driver-oriented categories, with each type displayed in its designated region. This segmentation ensures that private passenger information remains visible only to the passenger while still allowing necessary information sharing through the shared display device.

AI summary
The present disclosure relates to a method for adjusting a screen of a vehicle, wherein the screen is provided for a front passenger of the vehicle, and wherein it is originally provided to display at least one display element. The at least one display element is analyzed to determine, whether the at least one display element is dynamic and/or is provided only for the front passenger. Based on the determination, at least one static display element that differs from the display element originally provided for display is alternatively displayed from the driver's perspective.
