AUTONOMOUS & CONNECTED VEHICLES
The data-driven road to automated driving JACE ALLEN | ADAS/AD ENGINEERING AND BUSINESS DEVELOPMENT, DSPACE INC.
Data replay and enrichment tools help analyze driving scenarios and verify simulations based on real-world events. For ADAS and highly automated driving (HAD) applications, the road to homologation--the process of showing a product meets regulatory standards and specifications -- is a long journey that begins and ends with the data. In fact, it’s all about the data. The moment the vehicle’s perception sensors capture data, a complex process begins. The data must be taken through an intensive series of checks and balances to validate standards and specifications, including safety and technical requirements. This process requires a powerful and flexible end-to-end, data-driven development tools. The first step toward homologation begins with data logging within the actual vehicle. Data logging allows engineers to evaluate the development, validation, and optimization of artificial intelligence (AI) algorithms and electronic controls for autonomous functions. Specifically, data logging supports the following activities: • • • • •
Using dSPACE ModelDesk and UAI technology, measurement data collected from the live image on the top is transformed into a 3D simulated scenario on the bottom to enable the testing of perception algorithms.

Data enrichment to train AI/machine learning algorithms Prototyping of sensor fusion and perception algorithms in the vehicle Playback of recorded data in the laboratory to simulate test drives and support large-scale simulation Real-time trajectory planning to determine the best position, velocity, acceleration, etc., of the vehicle in a driving scenario Motion control development for optimal control of the autonomous vehicle in reaction to changing parameters and system inputs
Autonomous prototype vehicles generate huge amounts of data (petabytes) from their numerous imaging sensors (lidar, cameras, radar, ultrasonic). Buses and networks (CAN, CAN FD, Ethernet, FlexRay, etc.) get this data where it needs to go. V2X interfaces such as DSRC (Dedicated Short-Range Communications) or 4G or 5G, as well as GPS or electronic horizon capabilities with HD maps are all typically part of the data logging system.
