Murata has introduced the SCHA600 a new MEMS (Micro-Electro-Mechanical Systems) 6DoF (Six Degrees of Freedom) inertial sensor that delivers high performance for safety-critical automotive applications. The sensor enables new ADAS (Advanced Driver-Assistance Systems) functionality and AD (Automated Driving) through data fusion with GNSS (Global Navigation Satellite System) and various perception sensors such as camera, radar, and lidar.

 

As a single package, 6DoF component integrated with GNSS and perception sensor for L2+ and higher-level autonomy, the SCHA600 provides centimeter-level accuracy regarding vehicle dynamics and position for safe, robust, and verified autonomous driving. The SCHA600 is also designed with extensive failsafe functions and error bits for diagnostics, such as internal reference signal monitoring, checksum techniques for verifying communication, and signal saturation/over-range detection.

 

The Device is designed with a unique diagnostic feature of Murata’s 3-axis accelerometer which continuously operates for self-test function by monitoring the sensor during measurement, this makes sure of the proper operation of the entire signal chain from MEMS sensor movement to signal conditioning circuitry for every measurement cycle.

 

The SCHA600 is suitable to be used in various applications including Advanced Driver-Assistance Systems (ADAS), Automated Driving (AD), Inertial Navigation for dead reckoning, Lane Keeping Assistant (LKA), Motion and position measurements, and Platform stabilization
