National Instruments (NI) showcased its Advanced Driver Assistance Systems (ADAS) Vehicle Radar Test System (VRTS) and Camera Hardware-in-the-loop (HiL) test system technologies for the first time in India, at the Automotive Testing Expo 2018. These products have been recently launched in India, specifically designed to help lower the cost of test, reduce time to market and future-proof testers for upcoming requirements, noted the company.
The NI VRTS demonstration displayed the automated radar measurement and obstacle simulation capabilities for vehicular radar systems. This system is based on NI PXI Vector Signal Transceiver, along with a Variable Delay Generator and high performance mmWave Radio heads, it explained. The company said this system, combined with the expertise of its partner Konrad Technologies, provides a flexible solution to test both hardware and software sub-systems of a vehicle. These sub-systems include radar sensors, ADAS sub-systems, and embedded software.
Like the radar, a camera is an important component of ADAS Systems, noted NI, with the camera being able to detect specific details about objects and identifying what they really are. The camera HiL test system demo showed how to effectively emulate impairments that can be present in an actual system, the company said. It does so by using the IPG Carmaker Software from IPG Automotive and running the models in real-time on an NI PXI Controller. These models communicate with the IPG Video Interface Box which simulates the image sensor and provides the same electrical signals to the camera controller that an actual image sensor would do.
NI also showcased it recently-launched FieldDAQ device, which has been developed for rugged, distributed and synchronised data acquisition from complex electromechanical systems like vehicles, aircraft and industrial equipment. In addition, the company also displayed technologies like HiL validation, electric motor controller HiL and infotainment test demo with e-call testing setup at the event.
Murali Ravindran, Director, Automotive, Global Business Development, NI, presented at the Expo on ‘the importance of end-to-end ADAS test for connected cars.’ The session showed that vehicles are increasingly relying on more centralised processing architectures and sensor fusion techniques, implying that sub-systems can no longer be tested entirely independently because they don't function independently. To fully prove out the safety of future vehicles, their safety systems will require end-to-end testing to ensure systems interact and function as expected, he explained. The current ADAS end up in a combination of several sensor fusions, his presentation said.
