車載用MEMSセンサ

ST offers a portfolio of MEMS automotive sensors qualified according to AEC-Q100. Our automotive sensor portfolio includes digital accelerometers with low and high g full scale, and digital 3-axis gyroscopes.

ST’s low g 3-axis accelerometers have advanced power-saving features and an extended temperature range that make them the ideal choice for non-critical automotive applications including telematics, navigation, infotainment and security. Our high g acceleration sensors feature an extended temperature range and are suitable for airbag applications in vehicle safety restraint systems.

Our 3-axis gyroscopes offer superior stability over time and temperature, and guarantee the level of accuracy required by the most advanced navigation systems embedding dead reckoning. ST’s 3-axis gyroscopes have a single sensing structure for motion measurement along all three orthogonal axes, while other solutions on the market rely on two or three independent structures. Our solution eliminates any interference between the axes that inherently degrades the output signal. The result is increased accuracy and reliability of motion-controlled functionalities.

ST’s MEMS automotive sensors are developed on the same technology platform used for high-volume MEMS at the core of many industrial and consumer applications.
