Example of ASG Integration
Here, we demonstrate the integration of asg into a popular, Compact family car Model with a simple electronic setup that sells over 100,000 vehicles annually
OBJECTIVE
Transition the vehicle fully, onto the ASG control platform
The system adheres to modular and hierarchical principles with openness at all levels. Modules are strategically placed to minimise distance to connected sensors and actuators, regardless of the vehicle subsystem they belong to.
Power is supplied via a single-wire power bus (12V, 24V, or 48V), and communication is handled by a two-wire ring channel.
Critically, all modules collectively form a common, globally accessible information window (or global state) which is updated synchronously according to a strict 1 ms synchronisation schedule.

The ASG system composition includes:
- A two-wire line for the information flow transmission channel (or two-wire data bus)
- A single-wire power supply bus for powering the power nodes (or high-power components)
- Modules integrated into the system (up to 30 modules)
- Cables connecting the system modules to sensors, actuators, and other vehicle systems

Zone controlled by each module
Each ASG system module performs the following functions:
- Information exchange via the communication channel interface
- Computation and execution of control functions (The number of which is determined by the control options/features)
- Conversion of signals from vehicle sensors into the vehicle state vector
- Protection functions against overload and short circuits (SC), acting as a fuse function
- System monitoring/supervision functions
Vehicle nodes connected to ASG modules
The table below shows how each ASG module connect to electromechanical nodes of the vehicle. With the ASG distributed control systems, we are able to reduce the number of nodes necessary from 210 to 129 since the functions of 81 nodes are already fulfilled by ASG ECU's . The other components and systems are controlled or powered by ASG.
Notice the load capacity of each control unit, there is plenty of opportunity to add more nodes to the zone without strain or risk.
