logiRECORDER HIL Simulation and Testing
Development and validation of autonomous vehicles and ADAS are extremely demanding processes that include real-life road testing and exhaustive laboratory-conducted simulations. While real-world road testing is the ultimate step before releasing an automotive product, many companies tend to replace it as much as possible with realistic software, and hardware-in-the-loop (HIL) simulations, which are less costly, offer greater controllability, and generally improve the test quality and validation coverage.
Simulations based on artificially generated sensory data are usable, but they do not represent the ultimate test and validation solution. A vehicle’s heterogeneous sensors generate a large amount of data, depend on various real-world parameters, and become interconnected in complex patterns that cannot be artificially generated for fully realistic simulations.
An example of this can be illustrated by a forward looking camera. While the camera may recognize objects with an extremely high accuracy in simulations with artificially generated and display projected road scenarios, it will present unexpected deficiencies when applied in road tests with real traffic situations and weather conditions such as rain, direct sun or fog.
Hardware-in-the-loop (HIL) simulations that integrate real electronics devices within the simulation environment provide higher levels of realism in simulations and tests.
The logiRECORDER Automotive HIL Video Logger is capable of playing back realistically restored recorded sessions, while simultaneously recording the Device Under Test (DUT) responses. The logiRECORDER directly interfaces DUTs through native interfaces, and fully exchanges the selected automotive sensors installed in a vehicle. The DUT receives data as expected within the car, and generates the programmed feedback.
