SUMACO MA3
车规级高性能测量单元
Automotive-grade High-performance Measurement Unit
SUMACO MA3是一款车规级惯性测量单元产品，主要面向辅助驾驶应用场景，该产品能够满足功能安全ASILB等级要求。
The SUMACO MA3 is an automotive-grade inertial measurement unit (IMU) product primarily designed for advanced driver assistance systems (ADAS) applications.
This product meets the functional safety requirements of ASIL B.
产品内部集成了三轴MEMS陀螺仪以及三轴MEMS加速度计,能够实现三轴角速度以及三轴加速度的状态测量。
产品出厂经过全温标定,实现了全温零偏、标度因数以及安装误差补偿,能够在宽温环境以及无卫星条件下持续提供精确的运动状态测量。
It integrates a three-axis MEMS gyroscope and a three-axis MEMS accelerometer, enabling the measurement of three-axis angular velocity and three-axis acceleration.
The product is factory-calibrated across the full temperature range, providing compensation for temperature-related zero bias, scale factor, and installation errors. It can continuously deliver precise motion state measurements in a wide temperature environment and under conditions without satellite signals.
