Small MEMS-based inertial measurement unit for autonomous vehicles

ACEINNA offers the new OpenIMU330B, a MEMS-based, small form factor high-performance 6-DOF inertial measurement unit that allows autonomous vehicles to accurately stay on track during turns and complex manoeuvres. Measuring only 11mm x 15mm x 3mm, the device is created for usage in ADAS and autonomous systems as well as for electronic stability control and Lane Keep Assist functions.

This triple-redundant architecture, coupled with the small, low-cost packaging, is designed to satisfy the challenging performance, reliability and cost demands of the automotive market.

“We are making it possible to quickly design in and integrate IMU guidance technology to AVG solutions critical for Level 3 ADAS systems,” says Mike Horton, CTO of ACEINNA. “This is the first and only affordable, highly compact and triple redundant IMU module on the market.”

The unit is powered by an ARM M4 CPU with an FPU. The module runs the OpenIMU open-source stack that incorporates an optimised full-state Kalman Filter for Attitude and GPS-Aided PVT measurement. A free tool-chain based on VS Code supports PC, MAC, and Ubuntu is provided.
