Hirain and Arbe radar selected for Level 3 vehicle program

Key Takeaways

• Hirain Technologies will supply and integrate Arbe Robotics’ ultra‑high‑resolution imaging radar for a Chinese automaker’s Level 3 driver‑assist program.
• Series‑production deliveries are slated for Q4 2027, ahead of the vehicle’s first build‑off.
• The partnership merges Hirain’s mass‑production expertise with Arbe’s 77 GHz ARS5400 chipset, offering ≤0.1° angular resolution and a 200 m detection range.
• The radar will feed raw high‑definition data to the vehicle’s central automated‑driving platform, supporting multiple brands under the same group.

Introduction

A major Chinese automotive group has chosen the imaging radar developed jointly by Hirain Technologies and Arbe Robotics for its forthcoming Level 3 automated‑driving passenger‑vehicle line. The decision covers several marques within the group and marks the first time the duo’s combined solution will move from prototype to series production.

What the Selection Means

Hirain’s Responsibilities

• System Engineering & Integration – Hirain will lead the end‑to‑end development of the radar module, from hardware design to software calibration.
• Manufacturing Scale‑Up – Leveraging its Tier‑1 automotive factories, Hirain will ramp to a volume capable of supporting multi‑brand production.
• Validation & Quality Control – Full‑vehicle validation, functional safety compliance (ISO 26262 ASIL‑D), and long‑term reliability testing will be overseen by Hirain.

Arbe’s Technical Contribution

• ARS5400 Chipset – Arbe supplies its 77 GHz, 4‑Tx/8‑Rx mmWave chipset, which delivers ≤0.1° angular resolution and 200 m range at 30 fps.
• Ultra‑High‑Resolution Imaging – The chipset creates point‑clouds comparable to short‑range lidar, enabling precise object classification in complex urban scenarios.
• Data Interface – High‑speed Ethernet (10 GbE) links the radar output directly to the vehicle’s central automated‑driving computer.

Timeline to Production

The schedule positions the radar deliveries four quarters ahead of the vehicle’s scheduled start of production, giving the automaker a buffer for integration and certification.

Technical Advantages for Level 3 Automation

Market Impact

• China’s Level 3 Segment – Analysts project China will host over 2 million Level 3‑capable vehicles by 2030, with a CAGR of ~30 %.
• Supply‑Chain Consolidation – By pairing a Tier‑1 integrator (Hirain) with a specialist chipset maker (Arbe), the partnership reduces the bill‑of‑materials (BOM) count and simplifies the supplier matrix.
• Competitive Edge – The imaging radar’s resolution rivals lidar at a fraction of the cost (≈US$120 per unit vs. $800–$1,200 for lidar), potentially lowering the price premium for Level 3 features.

Bottom Line

Hirain’s manufacturing muscle combined with Arbe’s cutting‑edge ARS5400 imaging radar creates a production‑ready Level 3 sensor solution that meets the demanding performance and safety criteria of China’s fast‑growing automated‑driving market. With series‑production slated for Q4 2027, the collaboration not only secures a foothold in a multi‑brand program but also sets a benchmark for cost‑effective, high‑resolution radar that could become the de‑facto standard for next‑generation driver‑assist systems.
