汽车传感器

ST可提供一系列符合AEC-Q100要求的MEMS汽车传感器。我们的汽车传感器系列产品包括量程范围从低重力加速到高重力加速度的数字加速度计以及数字式3轴陀螺仪。

ST的低重力加速度3轴加速度计具有先进的节能特性和宽广的温度范围，成为非关键性汽车应用中的理想选择，包括远程信息处理、导航、咨询娱乐以及安全。我们的高重力加速度加速度传感器具有更大的温度范围，适用于汽车安全约束系统中的气囊。

我们的3轴陀螺仪可提供卓越的稳定性，不随时间和温度变化，确保满足嵌入航位推算的最先进导航系统中的精度要求。这些三轴陀螺仪采用一种独立传感架构来测量3个正交轴上的运动，而市面上的其它解决方案则采用2或3种独立架构。我们的解决方案可以避免轴之间的干涉，因其会降低输出信号的质量。这样可以提高运动受控功能的精度和可靠性。

ST的MEMS汽车传感器都是在相同的用于大容量MEMS的技术平台上开发的，这是许多工业和消费类应用的核心所在。

New firmware fuses satellite data with vehicle-sensor data for advanced 3D navigation

TESEO DRAW sensor fusion firmware merges the satellite information with data from vehicle sensors such as the gyroscope, accelerometer, and wheel-speed sensors, to calculate location accurately in three dimensions including elevation. If the satellite signal is poor, TESEO DRAW compensates for the loss of accuracy, and if the signal becomes unavailable, navigation continues uninterrupted based on calculated location (dead reckoning).

With the new Teseo DRAW firmware, ST provides a unified platform comprising navigation engines, 3D positioning capability, and motion sensors. The firmware is loaded on Teseo III multi-constellation receivers.

New MEMS accelerometers for airbag central unit (ACU) complete ST’s airbag kit

STMicroelectronics has introduced two central airbag crash sensors alongside its peripheral crash sensors, airbag system ICs, and safety microcontrollers, creating a complete airbag-electronics kit that supports functional-safety requirements.

The AIS1120SX and AIS2120SX single- and dual-axis 120g in-plane MEMS accelerometers are designed to be mounted in the vehicle’s Airbag Control Unit (ACU) responsible for evaluating the sensor data and triggering the appropriate restraint system.

The sensors interact with an airbag system IC and a safety microcontroller, which coordinate airbag activation.

A choice of three airbag system ICs, the L9678P, L9679P, and L9680 meet the demands of applications ranging from entry or mid-level to high-end vehicles with multiple airbag firing loops. Click here for further information about airbag system ICs.
