In some HIL test cases, it is possible to access the electronic control unit (ECU) not only by its electrical interfaces. It it also possible to have mechanical access via electric load machines that mechanically simulate a passenger car’s steering wheel as a human-machine interface, for example. Depending on the requirements and applications, different load machines are used, such as rotary drives, spindle actuators, and highly dynamic linear motors. To deliver the desired values for these load machines in real time, a high synchronicity between the HIL simulator and the load machine controller is indispensable.
Technical Details
SCALEXIO:
Powerful and flexible dSPACE hardware-in-the-loop simulator
SCALEXIO TWINsync hardware:
External housing with a DS2656 FPGA Base Board and a DS5451 Custom I/O Module as the interface to the TWINsync components. The IOCNET connection makes it possible to use TWINsync hardware up to 100 m from the SCALEXIO simulator.
KEBA ServoOne:
Compact, high-performance motor control by KEBA Industrial Automation Germany GmbH for a high number of linear and rotary load motor systems from 2 to 450 ampere
Optional:
- EV1132 TWINsync Transfer Module:
Transfer element with spring terminals, e.g., to connect one or more remote sensor interface boxes (RSI)
- EV1117 Remote Sensor Interface (RSI):
Highly sensitive measurement device for analog signal sources or torque sensors.
