Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems for agricultural working machines require manual operator input for adapting control strategies, which can distract the operator and hinder efficient process control.
Innovation Solution
A driver assistance system that communicates with an external computer unit to receive and transmit data, allowing it to select control strategies based on external information and sensor measurements, thereby automating the adjustment of control strategies during the work process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operator input is used to adapt control strategies, then the operator can adjust control parameters, but the operator becomes distracted and work process efficiency decreases
Solution Approach 1:
The driver assistance system automatically adapts control strategies by receiving external information and sensor measurements, eliminating the need for manual operator input. The system serves itself by autonomously selecting and adjusting control parameters based on incoming data, thereby resolving the contradiction between ease of operation and work process efficiency
Solution Approach 2:
The manual mechanical input process is replaced by an automated electronic system that receives external information and sensor data. The driver assistance system substitutes the operator's manual control adaptation with automated electronic control, improving efficiency while maintaining operational flexibility
2Productivity
If automated control strategy selection is implemented, then operator distraction is reduced, but the system complexity increases
Solution Approach 1:
The driver assistance system performs multiple functions: receiving external information, processing sensor measurements, selecting control strategies, and adjusting control parameters. By consolidating these diverse functions into a single multi-functional system, the patent manages complexity while achieving automated control strategy selection that improves productivity
3Measurement precision
If external information is continuously received and processed, then control strategy accuracy is improved, but data transmission requirements increase
Solution Approach 1:
The system receives external information and sensor measurements continuously to improve control strategy accuracy, but only processes and acts on the specific data portions that are relevant for control decisions. This partial processing approach maintains high accuracy while managing data transmission requirements by focusing only on essential information
Data Source
AI summary
An agricultural working machine with a driver assistance system is disclosed. The driver assistance system controls driving functions of the agricultural working machine and at least one working assembly of the agricultural working machine in the context of performing a work process. The driver assistance system accesses a set of rules in the form of control strategies to control the at least one work assembly according to a specific control strategy. The driver assistance system includes an interface to communicate with an external computer unit, which is remote from the agricultural working machine, and through which data can be exchanged between the driver assistance system and the external computer unit. For example, the driver assistance system receives data from the external computer unit via the interface during the work process of the agricultural working machine, and selects the control strategy for performing the work process based on the data.
