SMI710 | Combined inertial sensor for vehicle dynamics control

Safe and economical integrated sensor solution, applicable in systems up to ASIL D requirements

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.

Benefits

Excellent vibration resistance and offset stability over temperature and lifetime

Wide range of customized signal monitoring options

Various communication interfaces available

Target applications

Roll-stability control

Active suspension systems

Roll-over sensing
