Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional prediction methods are used without context information, then the system complexity is low, but the prediction precision is insufficient
Solution Approach 1:
The system collects and stores context information (driving state, interaction type, timestamp) in advance during normal vehicle operation. This preliminary data collection enables the machine learning model to make accurate predictions without adding complexity to the real-time prediction process, as the data preparation work is done beforehand
Solution Approach 2:
A machine learning model serves as an intermediary between raw context information and prediction results. The model processes multiple context variables (driving state, interaction type, temporal patterns) and transforms them into actionable predictions, managing the complexity by encapsulating the analysis logic within the model rather than in the main system architecture
2Ease of operation
If context-sensitive adaptation is implemented, then the usability is improved, but the processing time increases
Solution Approach 1:
The system continuously pre-processes and stores context information in structured formats during normal operation, including driving state, interaction types, and temporal patterns. This preliminary organization of data allows the prediction model to quickly retrieve and analyze relevant information without time-consuming data preparation during critical moments
Solution Approach 2:
The system predicts multiple possible future interactions and prepares multiple adaptation scenarios in advance, rather than waiting to determine the exact needed adaptation. This excessive preparation ensures that the most relevant adaptation is already ready when needed, reducing actual processing time while maintaining high usability
3Reliability
If real-time prediction is implemented, then the driving safety is improved, but the computational load increases
Solution Approach 1:
The system performs predictions at multiple time horizons and prepares multiple potential adaptation scenarios simultaneously. By computing a set of possible future states and their corresponding adaptations in advance, the system ensures that safe adaptations are ready when needed, improving driving safety while distributing computational load over time rather than concentrating it at critical moments

AI summary
A method for producing a model (15) for automated prediction of interactions of a user with a user interface of a motor vehicle. Vehicle operating logs (11, 12, 13) are provided and each includes a record of a time sequence of user interactions with the user interface. Each of the user interactions recorded in the vehicle operating logs (11, 12, 13) is assigned context information (21, 22) that includes a functional category (21) of the user interaction and a driving state (22) of the motor vehicle at the time of the user interaction. Training data (14) are generated based on the vehicle operating logs (11, 12, 13) and the associated context information (21, 22). A context-sensitive interaction model (15) is trained by machine learning on the basis of the training data (14) to make a prediction about a future user interaction based on a time sequence of past user interactions.
