Overview
Watch the video to learn about our advanced vehicle-in-the-loop test system, which combines real vehicle sensors with virtual environments. Our over-the-air simulation generates virtual objects in real time directly at the ultrasonic sensor level - the test vehicle perceives these as real. This allows complex parking maneuvers and scenarios to be tested safely, in a controlled manner, and repeatedly, offering significant advantages over traditional test drives.
The solution is also suitable for demanding applications such as virtual homologation tests in accordance with UN regulations, such as DCAS (UN ECE R171). This reduces costs and increases safety and reliability.

FAQ
Q1: What is the main challenge in testing automatic parking assistance systems in the real world?
A1: Testing in the real world is risky due to potential vehicle damage if the system fails, and it is difficult to repeat the exact driving maneuvers multiple times for consistent validation.
Q2: How does the vehicle-in-the-loop system improve testing of automatic parking?
A2: It integrates real vehicle sensors with a virtual environment by simulating ultrasonic signals over the air, allowing safe, deterministic, and repeatable testing without physical risks.
Q3: What role does the ultrasonic transducer level simulation play in this system?
A3: Simulation at the ultrasonic transducer level allows the system to emulate sensor echoes from virtual objects realistically, making the vehicle’s sensors “believe” the virtual environment is real.
Q4: How does the system simulate the presence of other vehicles during testing?
A4: Virtual vehicles are placed in the simulated 3D environment in AURELION, and their presence is conveyed via modulated ultrasonic signals to the real sensors of the ego vehicle.
Q5: What makes this testing approach compliant with UN regulations?
A5: UN regulations like DCAS explicitly allow the use of simulation for virtual homologation, making this method an approved approach for validating automated driving functions.
Q6: What are the benefits of virtual homologation compared to traditional testing?
A6: Virtual homologation offers safer, more reliable, and cost-efficient testing by enabling repeatable scenarios without physical risk, reducing the need for costly and time-consuming real-world trials.
Q7: Who can help build and implement such a vehicle-in-the-loop testing system?
A7: dSPACE specializes in simulation and validation technologies and offers collaboration opportunities to develop customized VIL systems for automated parking and other ADAS functions.
