What STÄHLE GmbH does

STÄHLE GmbH is a German family-owned manufacturer of robotic systems for automated vehicle testing, founded in 1984 and headquartered in Wimsheim, Germany. The company designs and produces a modular portfolio of mechatronic actuators — driving robots (AUTOPILOT/SAP2000 series), steering robots (SSP3000, SspFrontFree), pedal robots (up to 2,000 N brake force), shift robots (up to 1 million cycle durability), and free-drive systems (SfpHybrid) — all controlled by a unified AUTOPILOT32 real-time software platform. The system achieves ±0.5 km/h speed accuracy and ±2 cm lane-holding tolerance via differential GPS, meeting WLTP, EPA, FTP-75, SAE J2951, and NCAP testing requirements. The company has installed over 1,400 systems at more than 200 customers across 40+ countries, including automotive OEMs, Tier-1 suppliers, and ADAS/autonomous driving developers.

The business model combines precision hardware sales (modular robot systems), software licensing (AUTOPILOT platform with proprietary GUIs for emission and track-driver workflows), and aftermarket services (spares, remote diagnostics, updates). Sub-brands include AUTOPILOT for driving robots, SDrive for drive-by-wire path-following, and DriverModule for simulation-to-test-track bridging (SIM/HIL/VIL/PG) with integrations to IPG CarMaker, AVL DRIVINGCUBE, and MATLAB/Simulink. Go-to-market is event-driven (Testing Expo series, ADAS California, SIAT, VIL Tour) supplemented by regional channel partners in the USA, China, India, Korea, and DACH Europe, with direct engineering sales at the Wimsheim headquarters responding within 24 hours. Customers are exclusively enterprise (automotive OEMs, Tier-1s, regulatory bodies, test facilities), with relationships often spanning decades. The company is ISO 9001 certified, family-managed by Dieter, Klaus, and Kurt Stähle, and reports no external funding or institutional ownership.
