SMI860 | Combined inertial sensor for vehicle dynamics control

Reliable operation due to excellent vibration resistance

SMI860 is especially designed to support safety and ADAS functions with ASIL rating: ESP®, roll-over sensing, adaptive cruise control, hill-hold control, and short-term localization for ADAS functions. The SMI860 is a five axis sensor measuring yaw rate (Ωz), roll rate (Ωx) and acceleration (axyz).

It provides all relevant inertial signals in just one sensor. Subsequent system algorithms will use these sensor signals to compute the dynamical driving state of a vehicle or its position.

Benefits

Excellent vibration robustness and offset stability

Developed for systems with requirements up to ASIL D

Target applications

ESP®

Roll-over sensing
