Vehicle Control Unit Self-Configuration via Storage Evaluation Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle configuration systems require external tools and prior knowledge of functional and control units for parametrization, making it costly and inefficient to configure or reconfigure control units post-manufacturing.
Innovation Solution
A configuration system with a parametrizing unit and storage device that includes evaluation rules, allowing for fully automatic configuration of control units by interpreting configuration information for both the vehicle and control units, enabling parametrization and initialization without external tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If external tools and prior knowledge are used for parametrization, then configuration can be performed, but logistical costs increase and efficiency decreases
Solution Approach 1:
The control unit autonomously configures itself by reading configuration information from the storage device and processing it through its own processor, eliminating the need for external parametrizing tools and personnel. This self-service mechanism directly resolves the contradiction by enabling configuration capability while simultaneously improving efficiency and reducing logistical costs.
Solution Approach 2:
Configuration information is pre-stored in the storage device before the control unit needs to be configured. This preliminary preparation of configuration data allows the control unit to perform self-configuration without requiring external tools or prior knowledge, thereby improving configuration efficiency while maintaining ease of manufacture.
2Ease of manufacture
If external tools are used for parametrization, then control units can be configured, but device complexity increases
Solution Approach 1:
The configuration functionality is extracted from external tools and integrated directly into the control unit itself. The control unit's processor reads and processes configuration information internally, eliminating the need for external parametrizing tools. This extraction reduces system complexity while preserving configuration capability.
Solution Approach 2:
The control unit is designed with multi-functionality, serving both as the controlled device and as its own configuration tool. The processor performs both control functions and configuration processing functions, eliminating the need for separate external tools. This universality reduces device complexity while maintaining ease of manufacture.
3Ease of manufacture
If conventional parametrization methods are used, then control units can be configured, but time consumption increases
Solution Approach 1:
The control unit performs self-configuration by autonomously reading configuration information from the storage device and processing it through its own processor. This eliminates the time-consuming manual intervention required by conventional parametrization methods, significantly reducing configuration time while maintaining configuration capability.
Solution Approach 2:
The configuration process is designed to occur automatically and continuously as part of the control unit's operation, rather than as a separate manual step. The processor continuously reads and processes configuration information, eliminating idle time and interruptions associated with conventional methods, thereby reducing overall configuration time.

AI summary
A configuration system of a vehicle has at least one functional unit, a control unit pertaining to the functional unit, and a parametrizing unit provided in the vehicle, which is operatively connected with the control unit. The configuring system includes a storage device which can be read out by the parametrizing unit and which contains configuration information for the control unit, by which configuration information a parametrizing of the control unit can be carried out. The storage device additionally contains configuration information for the vehicle, in which case the storage device contains evaluation rules by which the parametrizing unit can determine configuration information for the configuration of the control unit from the configuration information for the vehicle and the configuration information for the control unit and can configure the control unit.
