Key Takeaways
- Hirain Technologies wird ein Imaging-Radar bereitstellen, das auf dem ultra-hochauflösenden Chipset von Arbe Robotics für das Level-3-Autonomes-Fahrprogramm eines chinesischen Automobilherstellers basiert.
- Serien-Produktionslieferungen sind für Q4 2027 geplant, vor Beginn der Fahrzeugmontage.
- Das Radar kombiniert Hirains System-Engineering, Validierung und Hoch-Volumen-Fertigung mit dem 77-GHz-Chipset von Arbe, das ≤0,1° Winkelauflösung und >200 m Reichweite liefert.
- Die Partnerschaft erweitert die Zusammenarbeit der beiden Unternehmen von ADAS zu voller Level-3-Automatisierung und positioniert das System für den Multi-Marken-Einsatz im Portfolio der Gruppe.
Overview of the Selection
Eine große chinesische Automobilgruppe hat das Hirain-Arbe Imaging Radar als primären Sensor für ihr bevorstehendes Level-3-automatisiertes Personen-fahrzeug-Programm ausgewählt. Die Entscheidung deckt mehrere Marken innerhalb der Gruppe ab und signalisiert eine breite Einführung statt eines Pilot-Modells. Hirain übernimmt End-to-End-Verantwortlichkeiten – Design, Fertigung, Integration, Validierung und Qualitätssicherung – während Arbe das Kern-Radar-Chipset liefert, das hochauflösende Daten an den zentralen Autonom-Fahr-Controller des Fahrzeugs speist.
Partnership Expansion
| Aspect | Hirain’s Role | Arbe’s Contribution |
|---|---|---|
| System Development | Lead architecture, integration, and vehicle-level validation | Provide ultra-high-resolution radar chipset |
| Manufacturing | High-volume automotive-grade production (AEC-Q100 qualified) | Chipset fabricated in 28 nm CMOS |
| Quality & Validation | Full-stack testing, ISO 26262 compliance (ASIL-D) | Deliver calibrated sensor data streams |
| Delivery Timeline | Series-production start Q4 2027 | Chipset availability aligned with Hirain’s schedule |
Technical Highlights
- Frequency & Bandwidth: 77 GHz FMCW operation with 4 GHz instantaneous bandwidth.
- Angular Resolution: ≤0.1° (up to 10× finer than conventional 77 GHz radars).
- Detection Range: >200 m for high-RCS targets; >150 m for low-RCS pedestrians.
- Field-of-View (FoV): 200° horizontal coverage achieved through a stacked-antenna array.
- Data Rate: Up to 2 Gbps raw radar data, pre-processed to 200 Mbps for the vehicle’s central computer.
- Environmental Robustness: Operates from –40 °C to +125 °C, meets IP68 sealing standards.
These specifications enable reliable perception of complex urban scenarios—critical for Level 3 functions such as traffic-jam chauffeur, lane-keeping with automatic overtaking, and high-speed highway cruising.
Production Roadmap
- Prototype Validation: Completed Q2 2025, including hardware-in-the-loop (HIL) testing on the automaker’s development vehicle.
- Pilot Production: Limited run of 5,000 units scheduled for 2026 to support pre-series vehicle builds.
- Series Production: Full-scale manufacturing to commence Q4 2027, targeting an annual output of 150,000 radar modules for multi-brand deployment.
Hirain’s established automotive supply chain and Arbe’s proven chipset design reduce risk and accelerate time-to-market for the Level 3 program.
How It Stacks Up Against Conventional Radar
| Feature | Hirain-Arbe Imaging Radar | Traditional 77 GHz FMCW Radar |
|---|---|---|
| Angular Resolution | ≤0.1° | 1–2° |
| Horizontal FoV | 200° | 120°–150° |
| Maximum Range | >200 m | 150–180 m |
| Data Throughput | 2 Gbps (raw) | 500 Mbps (raw) |
| Integration Level | Full sensor-fusion ready, OEM-grade software stack | Sensor-only, requires external processing |
| Production Volume | 150k units/yr (target) | 100k units/yr (typical) |
| Compliance | ISO 26262 ASIL-D, AEC-Q100 | ISO 26262 ASIL-B, AEC-Q100 |
The table illustrates the leap in resolution and field coverage that the Hirain-Arbe system brings to Level 3 applications, reducing reliance on complementary LiDAR or camera arrays.
Implications for Level 3 Automation
The integration of ultra-high-resolution radar directly into the vehicle’s perception stack provides several strategic advantages:
- Redundancy: Radar’s immunity to adverse lighting complements camera-based systems.
- Scalability: A single sensor package can serve multiple vehicle models, lowering BOM cost.
- Regulatory Readiness: ASIL-D compliance aligns with upcoming Chinese autonomous-driving safety mandates.
By delivering a sensor that meets both performance and volume-manufacturing criteria, Hirain and Arbe are positioning the Chinese automaker to meet its planned 2029 market launch for Level 3 vehicles.
Bottom Line
Hirain Technologies and Arbe Robotics have cemented a partnership that delivers an imaging radar capable of the resolution, range, and reliability required
