Solution Overview
Problem
Vehicle functions are often difficult to modify or update without visiting a workshop, requiring hardware replacement, which is disruptive and inefficient.
Innovation Solution
A method for starting up a new program package on vehicle computing units, involving loading, validating, and deploying the package, which can be done wirelessly, and includes emulation and authentication to support various hardware platforms, allowing for dynamic function assignment and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle functions are implemented statically during manufacture, then hardware reliability is improved, but adaptability and ease of updating deteriorate
Solution Approach 1:
The system separates vehicle functions into static hardware components and dynamic software program packages. The program packages are divided into manageable units that can be independently loaded, validated, and deployed to specific computing units, allowing updates without hardware changes.
Solution Approach 2:
Program packages are copied from a central archive to a vehicle-specific archive, and then deployed to target computing units. This copying mechanism enables distribution and updating of software functions across multiple computing units without modifying the underlying hardware.
2Manufacturing precision
If program packages are loaded and deployed manually in workshops, then validation accuracy is improved, but productivity and time consumption deteriorate
Solution Approach 1:
The system implements automated validation and deployment processes. The validation unit automatically validates program packages against validation rules, and the deployment unit automatically deploys validated packages to appropriate computing units, eliminating the need for manual workshop intervention while maintaining validation accuracy.
Solution Approach 2:
The system incorporates validation rules and automatic feedback mechanisms to ensure program packages meet required standards before deployment. The validation unit provides feedback on whether packages are suitable for deployment, enabling automated decision-making while maintaining high validation accuracy.
3Manufacturing precision
If program packages are validated manually, then validation thoroughness is improved, but time consumption and operational complexity deteriorate
Solution Approach 1:
Validation rules are prepared in advance and stored in the validation unit. Program packages are validated against these pre-configured rules automatically during the deployment process, eliminating the need for time-consuming manual validation while maintaining thoroughness through comprehensive rule sets.
4Adaptability or versatility
If hardware is replaced to update vehicle functions, then functional capability is improved, but cost and operational disruption deteriorate
Solution Approach 1:
The system replaces mechanical hardware replacement with software-based program package deployment. Instead of physically replacing hardware components to update vehicle functions, the system loads and deploys software packages to existing computing units, dramatically reducing cost and operational disruption while maintaining functional capability.
