Context-Aware Camera Display Mode Switching in Motor Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems for motor vehicles lack user-friendly and needs-based switching between different views on the display device, often requiring manual input or relying on automatic activation without considering driver preferences or vehicle conditions.
Innovation Solution
A method and camera system that record and learn the driver's behavior and vehicle conditions to automatically activate preferred display modes based on measurement parameters, such as global position and driving status, allowing seamless switching between views without unnecessary changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input is required to switch between different views on the display device, then the driver can select preferred views, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically switches between views based on vehicle status and learned driver preferences without requiring manual input. The camera system self-adjusts the displayed view by detecting vehicle conditions (reverse gear, cornering, parking brake) and autonomously selecting the appropriate operating mode that the driver previously preferred in similar situations.
Solution Approach 2:
The system learns from driver behavior by monitoring which views the driver manually selects in different vehicle conditions. This feedback is stored and used to automatically predict and switch to the driver's preferred view in similar future situations, continuously improving the ease of operation through adaptive learning.
2Ease of operation
If automatic view switching is implemented without considering driver preferences, then view switching is simplified, but the system may activate unwanted views that do not match driver needs
Solution Approach 1:
The system performs preliminary learning during the acquisition phase by monitoring driver manual selections and storing the associations between vehicle conditions and preferred views. This preliminary action builds a knowledge base that enables accurate automatic view selection later, ensuring both ease of operation and reliability.
Solution Approach 2:
The system uses the stored driver preference data to autonomously determine the appropriate view without manual intervention. By serving itself with learned preferences, the system achieves reliable automatic view switching that accurately reflects driver needs while maintaining operational simplicity.
3Adaptability or versatility
If the system continuously switches between views based on real-time vehicle status, then the display remains relevant to current conditions, but unnecessary view changes may occur
Solution Approach 1:
The system applies partial action by only switching views when the vehicle status changes in ways that actually warrant a different view according to the learned preferences. Not all status changes trigger a view switch - only those that match patterns previously associated with driver-preferred view changes, thereby maintaining stability while preserving adaptability.
Solution Approach 2:
The system uses feedback from stored driver preferences to filter and evaluate status changes. By comparing current status changes against learned patterns, the system determines whether a view switch is truly necessary, reducing unnecessary transitions while maintaining appropriate adaptability to meaningful condition changes.

AI summary
The intention is to disclose a solution enabling a display device (3, 3') in a motor vehicle (1) to be operated in a particularly user-friendly and requirement-compatible fashion. In a method according to the invention for displaying images on a display device (3, 3'), at least one camera records image data relating to an area in the surroundings (10 to 13) of the motor vehicle (1). The display device (3, 3') is operated in at least two operating modes which differ from one another in the view of the surroundings (10 to 13) on the display device (3, 3'). An operating mode of the display device (3, 3') is activated on the basis of an input by an operator. When the operating mode is activated by the operator, a data value which outputs this operating mode is stored in a memory device (7, 7') with an assignment to a current value of at least one measuring parameter (global position) of the motor vehicle (1). After this value for the measuring parameter occurs again, the assigned operating mode of the display device (3, 3') is activated automatically. A camera system (2) which is capable of learning is also made available for a motor vehicle (1).
