Inertial sensor with ASIL B for semi-autonomous driving

Application & Technical Summary


SMI240 is a 6in1 inertial sensor with ASIL B rating. The sensor is capable of measuring all 6 degrees of freedom: yaw/pitch/roll rate and acceleration in x/y/z directions.

Typical applications include L2 semi-autonomous driving, hands-free driving and positioning applications.

Product benefits

  • On-board safety controller for monitoring of sensor functions
  • Developed according to ISO26262 for systems with safety targets up to ASIL B

Target applications:

  • L2 semi-autonomous driving
  • Hands-free driving
  • Positioning applications
  • Other ADAS functions

for hands-free driving

Detects changes in the vehicle position
