High Performance Inertial Sensor for HAD Systems (SMU2xy)

Bosch Semiconductors

Highly automated driving (HAD) requires precise informations about the vehicle’s movements.
The sensor data is used for lane keeping during a safe stop or to verify movement information derived from camera image or steering angle sensor. The SMU2 family offers excellent offset stability over the entire temperature range.

SMU2 sensors feature a single-axis gyroscope and a 3-axis accelerometer.
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 capable of measuring all 6 degrees.
