Vehicle Management Control Device for Remote Software Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating and adapting vehicle control software require physical intervention by a technician, as vehicles protect their control software against external access, making wireless transmission of functions through public interfaces challenging.
Innovation Solution
A management control device within the vehicle acts as an intermediary, receiving functions from an external server via a wireless interface, decoding, and implementing them in the vehicle's control devices, allowing for remote software updates and adaptations without direct public interface access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control software is protected against external access to ensure security, then reliability is improved, but ease of operation deteriorates because remote updates become impossible
Solution Approach 1:
The patent introduces a management control device as an intermediary component within the vehicle's internal network. This mediator receives update commands from external sources and securely distributes them to protected control devices, thereby enabling remote updates without compromising the security protection against direct external access.
2Reliability
If control software is protected against external access, then reliability is improved, but productivity deteriorates because physical technician intervention is required for updates
Solution Approach 1:
The management control device serves as an internal intermediary that receives update commands from external sources and securely distributes them to protected control devices. This eliminates the need for physical technician intervention while maintaining security, thereby significantly improving update efficiency and productivity.
3Ease of operation
If a management control device is introduced to enable remote updates, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The management control device is designed to perform multiple functions: it manages software updates, handles diagnostics, and coordinates communication between external sources and internal control devices. By consolidating these functions into a single multi-functional component, the patent minimizes the increase in overall system complexity while enabling remote update capabilities.
