<h2>What is HIL</h2>
</div>
</div>
<div data-id="5c1bdfb" data-element_type="widget" data-widget_type="text-editor.default">
<p> Hardware-in-the-Loop, or hardware and software simulation, is an approach to testing the software of electronic systems by connecting them to a simulator of adjacent systems or environments.<br /> For example, to work out the algorithms of the chassis release system, a special computer is connected to the control unit with an accurate programming model of the chassis and an accurate simulation of signals from the chassis. For the control unit, this looks like a regular operation with a real unit.</p>
<p><img class="img-responsive" src="http://www.olnio.com/uploads/service/2ab756faccc97d99cce25b2c99565b93.jpeg" alt="" width="600" height="185" /></p>
<p> HIL is to a device like a flight simulator for a pilot. HIL spoofs signals by tricking the “senses”, trains and tests “skills”, algorithms and scripts.<br /> All systems interact with real signals and in real time. Today, simulators of control units and objects, sensors, environment, related systems and controllers, the whole system are created in this way. Control units, hydraulic and electric drives, communication and navigation systems, radars, autopilot systems, etc. are tested.</p>

<h2>HIL and prototyping in R&D</h2>
</div>
</div>
<div data-id="4d462bf" data-element_type="widget" data-widget_type="text-editor.default">
<p> HIL is also used for product prototyping. The mock-up models and “imitates” the behavior of the product itself (which is still being developed) when interacting with the environment. The HIL system simulates the environment of the product.</p>
<p><img class="img-responsive" src="http://www.olnio.com/uploads/service/8b61999d49ee629eaa4f2dbd5176b314.jpeg" alt="" width="600" height="151" /></p>
<p> </p>
<p>HIL simulators can be used on both sides, which allows you to smoothly, as products and algorithms are ready, move from two-sided simulation to testing real systems.</p>
<p> </p>
<p><span style="font-size: 18pt;">Test earlier, safer, cheaper</span></p>
<p> </p>
<p> HIL tests begin long before the product, related systems or landfill is ready. In advance, in laboratory conditions, you can see the behavior of the system and better prepare for field tests. In HIL mode, thousands of semi-natural tests are performed in a short time - without endangering people and equipment.</p>
<p> </p>
<p><span style="font-size: 18pt;">HIL for software debugging and improvement</span></p>
<p> The results of HIL's experiments provide feedback to embedded software developers and help them implement, fix, and improve bold innovations. HIL helps you reproduce an experiment, test hypotheses, and gather statistics. At the same time, unlike computer simulation, work is carried out with real devices and signals - and in real time.</p>
<p> </p>
<p><span style="font-size: 18pt;">HIL platform National Instruments</span></p>
<p> National Instruments' platform builds on over 40 years of experience in automated measurements and testing of the latest electronic devices, electromechanical systems, automatic control systems, bench tests and scientific experiments.</p>
<p> The platform has collected the best practices for solving problems in aviation and space, energy, automotive, shipbuilding, railway transport, medical instrumentation, and nuclear physics. Today it is an example of a solid, yet open and dynamically developing platform for responding to new engineering challenges.</p>
<p> </p>
<p> A typical HIL system includes a test object, data acquisition equipment, and a software model that receives, processes, and outputs signals to simulate real-world scenarios.</p>
<p> <span class="boldspan" style="font-weight: 400;">The execution of the model</span> must take place in hard real time, which in modern devices means a time scale and delay in units of microseconds. Hardware for software and hardware simulation is based on real-time processors and FPGAs, as well as special software such as NI VeriStand.</p>
<p> <span class="boldspan" style="font-weight: 400;">Data acquisition equipment</span> , as a rule, also includes special solutions for switching and signal conditioning and additional devices. So, it is typical to use external powerful amplifiers, load simulators, devices for simulating a break and introducing other malfunctions.</p>
<p> <span class="boldspan" style="font-weight: 400;">Rigging or cable</span> solutions for convenient and reliable connections take a special place in large systems designed to test different units.</p>
<p> <span class="boldspan" style="font-weight: 400;">Software for automation of tests</span> , analysis and storage of results, special communication protocols, loads, simulation of faults, etc. complement the functionality of the system.</p>

<p> A typical HIL system includes a test object, data acquisition equipment, and a software model that receives, processes, and outputs signals to simulate real-world scenarios.</p>
<p> Stands for large tasks are a complex of interacting systems and HIL simulators under common control. The stand also provides solutions for signal switching, for connecting various versions of models, breadboards and real systems, and simulates malfunctions. In addition, everything that happens is recorded for instant and delayed analysis. </p>
<p> The stands allow you to study situations that are either impossible or highly undesirable to create in real operation.</p>
<p> The equipment and software of the stand should provide:</p>
<ul>
<li>Working out various scenes of exploitation in real time;</li>
<li>Simulation of signals from sensors and actuators (physical influences or electrical signals);</li>
<li>The ability to replace real systems (electronic units, hydraulic and mechanical systems, etc.) with their HIL simulators and vice versa;</li>
<li>Simulation of hardware faults and software errors;</li>

<h3>HIL modeling of ADAS systems and unmanned vehicles</h3>
<p> ADAS driver assistance systems and unmanned vehicles are increasingly shifting concerns about the safety of the driver, passengers and other road users to automation in the form of sensors, cameras, lidars, radars and, above all, computer algorithms in vehicle systems. </p>
<p> </p>
<p> Algorithm testing and system testing is complicated by the required speed of time to market, maximum requirements for system reliability, a variety of sensors and their testing methods, constant updates and changes in requirements, technologies and expectations.</p>
<p> HIL software simulations and tests help meet this challenge.</p>
<p> </p>
<p> </p>
<h3>YEA Engineering ADAS-HIL Platform</h3>
<p> HIL systems for ADAS are designed to test both individual components of the system and their interaction within the framework of traffic scenarios. The ADAS-HIL platform in a typical configuration combines the following subtasks:</p>
<p> </p>
<p>• Hardware and software simulation for ECU</p>
<p>• Simulation of obstacles for vehicle radars</p>
<p>• Simulation of obstacles for lidars</p>
<p>• Projection of video images onto the optical lens of the camera</p>
<p>• Simulation of GPS / GLONASS signals</p>
<p> </p>
<p> </p>
<h3>HIL testing of radar sensors</h3>
<p> Simulation of radar sensor signals uses re-emission of the received radio signal with a delay and frequency shift. Dynamic obstacle simulation requires a wide instantaneous bandwidth and exceptional performance, which is achieved through tight integration of FPGAs in NI radios.</p>
<p> </p>
<p> The NI VRTS (Vehicle Radar Test System) kit provides object simulations for radars in the 76-81 GHz range. The minimum configuration for output control provides up to 4 simulated targets and is housed in an 8-slot PXI chassis. For more complex cases in research tasks, multi-module configurations are used based on one or more 17-word chassis.</p>
<p> </p>
<p>Key parts of the VRTS:</p>
<p>• NI 5551 - VDG variable delay module with 4 GHz bandwidth</p>
<p>• NI 5840 - VST vector transceiver with FPGA</p>
<p>• NI mmRH-3608 - mmWave interchangeable radio heads</p>
<p> </p>
<p><em><span class="boldspan" style="font-weight: 400;">Test radar sensors in Audi</span></em></p>
<p><em>“The widest bandwidth and low latency of the NI VST have</em></p>
<p><em>allowed our radar sensors to be tested</em></p>
<p><em>like never before. We were able to</em></p>
<p><em>simulate a lot of scenarios in the early stages and solve problems</em></p>
<p><em>that we could not have noticed before. ”</em></p>
<p> </p>
<p><em>Nils Koch, Audi AG</em></p>
<p> </p>
<h3>HIL testing system for radar sensors YEA Engineering</h3>
<p> The system is part of the ADAS-HIL platform and serves to validate sensors, electronic control units and ADAS systems. Used by Tier 1 suppliers and automakers.</p>
<p> The system integrates an anechoic chamber, a set of control and measuring equipment, a positioning system and open-type software. This allows for common tests and provides the flexibility to create your own scenarios and measurements.</p>
