Vcarsystem presents a shift from conventional ADAS measurement systems to PCIe-based architectures enabling lossless acquisition and replay of massive sensor data streams. PCIe measurement technology integrates directly into high-performance ECUs, providing multi‑gigabyte bandwidth with minimal CPU load via DMA/RDMA. The same PCIe infrastructure supports high-performance replay (HOL) solutions, allowing recorded real‑world data to be injected back into the system for reproducible laboratory validation. This convergence simplifies system complexity, reduces costs and significantly accelerates ADAS function development and validation.

• PCIe enables scalable, lossless ADAS data acquisition up to multigigabyte per second bandwidth
• DMA/RDMA minimizes CPU load while capturing raw sensor and ECU data
• PCIe loggers can be reused as replay hardware without modification
• Replay HOL enables reproducible lab validation using real‑world driving data
• Combined logging and replay reduce system complexity, capex and development time
