HELIOS: ECU & Engine HILS System
The HELIOS platform is equipped with the functions required by any HILS system. The all-in-one design with integrated I/O boards and Interface boards makes the system compact and effective for quick building of HIL system. It is also a platform that enables high-speed inter-node communication and low-latency model synchronization to enable multi-node systems with multiple enclosures required for large-scale HILS.
Real-Time Simulation and Hardware-in-the-Loop with HELIOS HILS
Ideal platform for large-scale Hardware in the loop systems and integrated HILS systems
Vehicle systems are becoming more complex due to vehicle electrification, ADAS, and automated driving. For control development/verification, HILS corresponding to large-scale operations that use complex operations and third-party modeling tools for each functionality is needed. For example powertrain HILS (engine, transmission, battery, etc.) and Body Integrated HILS (such as system HILS/vehicle environment/weather environment/steering stability) working as one system is required.
A & D provides a highly scalable HILS platform for linking multiple CPUs and multiple chassis.
The control I/O board is equipped with fail circuits on-board, and no external board is required for fault simulation.
All I/O boards are equipped with a self-diagnostics function as a standard. If a problem occurs during the self-diagnostics test, the user can isolate the cause. It can also be used for pre-use inspection.
The system has an operation time monitor function and can monitor software operation time and power-on time. It can be used to manage the HILS equipment operation time.
