SMU200

High performance inertial sensor for HAD systems

Application & Technical Summary

SMI860

SMU200 features a single-axis yaw rate sensor (Ωz) and a 3-axis accelerometer (axyz).

Typical applications include localisation by combining the GNSS position information with the sensor’s data, resulting in a significantly more precise positioning. The combination of a SMU200 with two SMU210 makes a system capable of measuring all 6 degrees of freedom (yaw, pitch and roll rate as well as acceleration in x, y and z direction).

Product benefits

  • On-board safety controller for monitoring of sensor functions
  • Excellent offset stability over the entire temperature range
  • Developed according to ISO26262 for systems with safety targets up to ASIL D

Target applications:

  • Localisation
  • Other ADAS functions

Precise localisation

Detects smallest directional deviations
