Sirius is a Japan-based driving simulator platform for automotive R&D. Rather than simply selling software, it is positioned around a “Simulator as a Service” model, delivering the outcomes needed for experiments and evaluation tests. It can provide simulator equipment, CG and scenario data production, hardware integration, experimental environment setup, and operational support. It is a good fit for R&D teams that need a driving simulator but lack experience in modeling and system integration.
The platform works through several coordinated modules: Score handles executable files and project-level system configuration; UE4 is used for real-time, high-quality CG rendering; Re:sim manages multi-agent traffic flow and complex scenarios; S-Interface connects traffic participants such as vehicles, bicycles, motorcycles, and pedestrians; Function Extender supports complex scenario logic, CG display control, custom sounds/icons, motion systems, and external hardware integration. It also supports Multi-Player experiments and can connect to Simulink via S-Function, making it suitable for validating vehicle models and control algorithms.
The official site discloses fairly clear academic-oriented pricing: experimental environment setup is around 200,000–500,000 yen, equipment rental starts from 20,000 yen per month, and the Sirius usage fee is 30,000 yen for 1 month. Long-term licensing is 30,000 yen per month or about 150,000 yen per year. Training costs 50,000 yen per session, while technical support is quoted per request starting from about 5,000 yen. Consultation, meetings, and quotations are free, but we did not find a free edition or standard trial.
The main advantages are relatively manageable upfront adoption costs, plus the ability to customize CG, scenarios, and hardware connections around specific experimental goals. UDP communication, UE4 plugins, and Simulink integration also give it strong extensibility. The drawbacks are that self-service use has a high barrier to entry, and the official site also notes that considerable technical skill is required. Information for enterprise procurement is limited, including team permissions, data security and compliance, payment methods, and commercial pricing.
Sirius is best suited to universities, research institutions, and automotive R&D departments conducting experiments in ADAS, traffic interaction, ergonomics, and driving behavior. Its accessibility from China is unknown; cross-border procurement may involve issues with language, payment, hardware delivery, and on-site support. If a localized alternative is needed, options such as CARLA, CarMaker, rFpro, VI-grade, and dSPACE ASM may be worth evaluating.
