Hirain und Arbe Radar für Level 3 Fahrzeugprogramm ausgewählt

Hirain und Arbe Radar für Level 3 Fahrzeugprogramm ausgewählt

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:

  1. Redundancy: Radar’s immunity to adverse lighting complements camera-based systems.
  2. Scalability: A single sensor package can serve multiple vehicle models, lowering BOM cost.
  3. 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
