SMI710

Combined inertial sensor for vehicle dynamics control

Application & Technical Summary

SMI7xy

The SMI710 is a tri-axis (ayz, Ωx) combined inertial sensor specifically designed for premium vehicle dynamics control (VDC) functions, roll-stability control (RSC), and active damping systems (AD) but also for roll-over sensing (RoSe) functions.

Due to the combination of three chips in one housing, the SMI710 is able to measure data on the vehicle’s rotation around its roll axis. In addition, it delivers data on longitudinal and vertical acceleration to determine the dynamic state of the vehicle and to check the plausibility of the rotation rate signal.
