The dSPACE Simulator EcoLine system is based on dSPACE hardware-in-the-loop (HIL) technology. Five versions are available, each custom-made for a specific application. Features of the ready-to-go systems include convenient handling and a preconfigured HIL system. Function developers can perform HIL tests at an early stage, before integration tests are performed. A central DS1006 computer board enables calculation of processing-intensive real-time models, while an HIL I/O board, DS2202/DS2211, offers I/O interfaces and onboard signal conditioning. A wiring board provides ECU connection and integration of optional electric loads as well as a power unit for battery simulation, and a software package is also included. Special modules are added to the central system to create off-the-shelf packages including engine piezo, engine solenoid, transmission, vehicle dynamics, and body electronics.
