VI-grade’s HiL solution powered by Concurrent Real-Time for Automotive Applications
The Hardware-in-the-Loop (HiL) testing market is gaining momentum, following the development of vehicles with advanced driver-assistance systems (ADAS) capabilities. This growth is driven by the need for a solution that can cost-efficiently validate the number of electronic control units (ECUs) incorporated into these vehicles.
Additionally, innovative HiL solutions are also required to test electric vehicles (EVs) and validate the function of the battery unit and other power electronics components.
To answer these needs, VI-grade has developed AutoHawk, the new HiL solution (powered by Concurrent Real-Time) for automotive applications.
AutoHawk consists of real-time hardware, real-time OS, real-time software and I/O cards and is highly configurable, since both VI-grade real-time software and/or software from 3rd party can be installed on it.
In the same configuration, AutoHawk can work as a stand-alone Linux based high-power computer, as a HiL system or in combination with a driving simulator or on a real vehicle.
AutoHawk is a flexible HiL platform that can be used across the entire product development cycle, from concept to sign-off.
Autohawk comes in 3 standard configurations with the latest 8, 16 and 24 cores to manage your projects and log data. All systems come with a communication card that supports CAN, CAN FD, LIN and can be further expanded with multiple IO boards and other automotive communication protocols (FLEXRAY, SENT, EtherCat, Automotive Ethernet and more)
For on-vehicle applications, the AutoHawk systems can be provided in rugged chassis. The systems are highly configurable and provide 4-7 slots to include boards for IO, the most versatile being freely programmable FPGA boards.
An expansion chassis for signal conditioning and fault insertion is available along with programmable power supplies.
Applications
Desktop (Offline + SIL +MIL) AutoHawk can be used for off-line simulations, DoE, optimization loops
In-lab (HiL + SIL +MIL) These are the typical HiL applications in which a device under test (DUT) is connected to AutoHawk running real-time software
On-sim (HiL + DiL + SIL +MIL) These are HiL applications in which the driver sends inputs to AutoHawk through the driving simulator -it is useful to test corner cases and where the closed-loop inputs are essential
On-vehicle (HiL + ViL + SIL +MIL) These are HiL applications where virtual vehicle model runs on the real vehicle with mutual influence
Digital Twins (HiL + DiL + ViL + SIL +MIL) Driving simulator and real vehicle are fully synchronized and therefore affect each other's behaviour
Typical applications are: Electric drive system development, steering system integration, EPS calibration, Steering feeling, Fault injection, Benchmarking, X-by-wire redundancy validation, ADAS development (i.e. Lane Keeping, Emergency Braking, Blind Spot Detection, Traffic Sign Recognition, Autopilot)
Benefits
Open architecture thanks to Linux based operating system providing deterministic real time and allowing easy integration of 3rd party products
Multi-core technology providing more computational power and allowing for more complex XiL setups all in one system
Commercial off-the-shelf components to take advantage of the latest innovations in the market
Support for automotive communication protocols (CAN, LIN, Flexray,…)
