Moving to design architectures
The concrete realization of the abstract functionality is first considered in a technical architecture specification, referred to as functional design architecture. It specifies the refinements of analysis architecture for the realizations on a particular software and hardware platform (e.g. through partitioning and allocations of the abstract application functions). An illustration of this is shown in Figure 5. Here BrakeRR design function receives three different kinds of data: requested torque , wheel speed and vehicle speed . This function is connected to a local device manager sending the signal to the hardware function. This hardware function then provides the physical energy to BrakeTorque_RR.
In parallel with functions, EAST-ADL allows designing hardware architecture, consisting of sensors, actuators, power supplies and ECUs. Figure 6 shows a part of the hardware architecture where BrakeRR function from functional design in mapped to HW architecture. Sensor Encoder_RR provides Revolutions Per Minute via IOConnection to ECU_RR node which then sends the requests to the brake located in rear right. All the hardware components have an in port for power. ECU node component
