Efficient homologation of autonomous vehicles of SAE Level 3 and upwards requires testing and validation of software and hardware systems in the lab. This results in new challenges and requirements compared to traditional testing, such as simulation of validated sensor raw data with highest timing accuracy.
What do you need for lab-based homologation from SAE Level 3 via hardware-in-the-loop?
To overcome these challenges, a comprehensive end-to-end test architecture for the verification and validation of Level 3 functions in a controlled lab environment is needed. This includes the simulation of dozens of sensors simultaneously in real time and highly synchronized.
- Performance: Generation of realistic sensor data, i.e., in the same way as it would be generated in reality on the road.
- Synchronicity and low latency: Realistic sensor data must be fed into the autonomous driving function control units in a time-correlated manner.
- (Rest-) Bus Simulation: To satisfy the full AV stack, additional (rest)- bus data, such as steering angle and wheel speeds, is needed.
- Vehicle-to-X: Receive messages from other vehicles and the infrastructure.
- GPS/GNSS: Run-time GPS emulation for map-based localization.

dSPACE offers comprehensive solutions for the virtual homologation of automated vehicles: from physics-based sensor simulation, over real-time scenario simulation, to synchronous raw data insertion and closed-loop restbus emulation in Hardware-in-the-Loop (HIL) systems.
AURELION - Sensor-Realistic Simulation for ADAS/AD in Real Time
AURELION is a flexible software solution for sensor simulation and visualization. It enables you to integrate realistic sensor data into your processes for developing, testing, and validation of perception and driving functions. The same models can be used throughout various phases of development, for example in hardware-in-the-loop (HIL), software-in-the-loop (SIL), and vehicle-in-the-loop (VIL).
Environment Sensor Interface (ESI) Unit - Feeding digital data into camera, radar and lidar ECUs
Systems for autonomous driving use multiple environment sensors. To simulate the sensors in a HIL setup for sensor fusion and function testing, it is essential to accurately synchronize the stimulation of the individual sensors. The dSPACE Environment Sensor Interface Unit supports the time-correlated feeding of raw sensor data to one or more sensor ECUs.
SCALEXIO - Modular real-time system
The modular dSPACE SCALEXIO system can be used for hardware-in-the-loop (HIL) and rapid control prototyping (RCP) applications. It is highly scalable, provides high-performance processor technology for demanding real-time requirements as well as comprehensive, precise, and fast I/O capabilities.
SIMPHERA - The cloud-based, highly scalable solution for the simulation and validation of functions for autonomous driving
SIMPHERA is a software solution for simulating and validating functions for autonomous driving. It enables large-scale test execution in the cloud for software-in-the-loop (SIL) use cases, as well as a continuous workflow for hardware-in-the-loop testing.
