SMI860
Combined inertial sensor for vehicle dynamics control
Application & Technical Summary
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.
Product benefits
- Excellent vibration robustness and offset stability
- Developed for systems with requirements up to ASIL D
Target applications:
- ESP®
- Roll-over sensing
- Adaptive cruise control
- Short-term localization
- and other safety and ADAS functions
reliable operation
due to excellent vibration resistance
