SMI700 | Combined inertial sensor for vehicle dynamics control

SMI7xy

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

The SMI700 is a tri-axis (axy, Ωz) combined inertial sensor specifically designed for ESP® and premium vehicle dynamics control functions.

Due to the combination of three chips in one housing, the SMI700 is able to measure data on the vehicle’s rotation around its vertical axis (gyroscope, gyro). In addition, it delivers data on the lateral and longitudinal acceleration to determine the dynamic state of the vehicle and to check the plausibility of the rotation rate signal.

Benefits

Excellent vibration robustness and offset stability

Wide range of customized signal monitoring options

Various communication interfaces available

Target applications

ESP®

Adaptive cruise control

Other safety and ADAS functions
