Vehicle-Internal Update Transmission Device for Motor Vehicle Control Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle update systems external to the vehicle lack the ability to consider vehicle-specific conditions and energy management, leading to potential battery drain and inefficient updates.
Innovation Solution
A system where the update package is managed and installed internally within the motor vehicle, allowing for vehicle-specific prioritization and flexible distribution across the network, with a master control device coordinating the update process and considering dependencies between control units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transmission device is arranged external to the motor vehicle to manage update package transmission for multiple vehicles, then the update package can be made available for a plurality of motor vehicles, but the motor vehicle-specific conditions and energy management cannot be considered, leading to potential battery drain and inefficient updates
Solution Approach 1:
The system segments the update management function by introducing a vehicle-internal transmission device that operates autonomously within each motor vehicle. This transmission device receives update packages from external sources and independently manages their distribution to control units, allowing each vehicle to handle updates independently while maintaining the ability to serve multiple vehicles through the external transmission device
Solution Approach 2:
The vehicle-internal transmission device acts as an intermediary between external update sources and internal control units. It receives update packages externally, processes them according to vehicle-specific conditions and energy availability, and then distributes them internally, thereby bridging the gap between external update distribution and internal vehicle requirements
2Device complexity
If the external transmission device downloads the update package into the motor vehicle without internal management, then the transmission process can be simple, but the energy store may be emptied and the motor vehicle may no longer be drivable
Solution Approach 1:
The vehicle-internal transmission device performs preliminary actions by receiving and storing update packages in advance before they are installed on control units. It can buffer update packages and manage their installation timing based on energy availability and vehicle operational conditions, preventing situations where the vehicle runs out of energy during critical operations
Solution Approach 2:
The system implements feedback mechanisms where the vehicle-internal transmission device monitors energy store levels and vehicle operational status, using this information to control the timing and pace of update package installation. This feedback loop ensures that updates are installed only when energy and operational conditions permit, maintaining vehicle reliability
3Speed
If the update package is distributed without considering control unit dependencies, then the distribution process can be faster, but the installation may fail due to unmet software dependencies
Solution Approach 1:
The system dynamically adjusts the update installation process by evaluating control unit dependencies in real-time. The vehicle-internal transmission device can reorder update installations based on detected dependency relationships, pausing dependent updates until their prerequisites are installed, thereby maintaining both speed and correctness through adaptive process management
