Update Manager is an embedded software solution for rolling out update campaigns across the entire vehicle architecture.
Modern vehicles include a wide range of ECUs, from simple controllers to high-performance processors that interact in different ways. Update Manager identifies and maps these hardware and software components and ensures communication between them.
All update packages are triggered and downloaded through a connection to a cloud backend. As a central control element within the vehicle architecture, MICROSAR Connect | Update Manager provides the foundation for managing updates across individual vehicles and entire fleets with over-the-air capabilities.
Key Capabilities for Update Management in Connected Systems
- Central solution to manage update campaigns across the vehicle or the entire networked system
- Maps the full network, from sensors and microcontrollers to zonal architectures and HPCs
- Interacts reliably with base software without tight dependencies
- Flexible integration into POSIX-based systems
- Supports encrypted updates for safety-related components
- Modular design enables flexible integration across different hardware environments
- Central orchestration ensures deterministic and reliable update processes without creating additional attack surfaces in the backend
- Optional hierarchical orchestration supports distributed development and rollout of update functions
- Clearly defined interfaces simplify the implementation of manufacturer-specific requirements
- Scales from individual vehicles to whole fleets
- Applicable across automotive, medical technology, and robotics systems
- Connects to third-party or proprietary backends through defined interfaces
- Supports compliance with ISO 24089, UNECE SUMS, and CSMS
Key Functions for Update Management
State Tracing and Control
- Monitor vehicle condition across your fleet
- Plan update campaigns for vehicle fleets and similar system structures
- Define and sequence ECU updates, including parallel execution where required
- Create and validate update instructions in the backend
Package Management in the System
- Mapping of the network, creation of an inventory list
- Dependency and progress monitoring
- Interruption and resumption of running updates
- Execution of individual ECU updates
- Error detection and rollback handling
- Storing and staging packages for distribution
HPC Updates
For larger ECUs such as high-performance computers (HPCs), the Vehicle Update Manager also supports distributed deployment. An additional instance runs on the HPC, abstracts its internal complexity, and manages sub-update campaigns.
This enables a hierarchical update structure within the vehicle and supports distributed development and release of update functions.
