SCHA600 6-DOF XYZ-Axis Gyroscope & XYZ-Axis Accelerometer with Digital SPI Interface
Murata
has developed a new MEMS (Micro-Electro-Mechanical Systems) 6DoF (Six Degrees of Freedom) inertial sensor that realizes 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.
The product
delivers the best performance available for automotive applications in regard to bias stability and noise.
The orthogonality of the measurement axes
is calibrated at Murata, allowing system integrators to skip this costly and performance-critical process step.
This new sensor
is a single package 6DoF component to be integrated with GNSS and perception sensors for L2+ and higher levels of autonomy.
The new sensor
enables centimeter-level accuracy in regard to vehicle dynamics and position, enabling safe, robust and verified autonomous driving.
Extensive attention
has been given to guarantee operation during high mechanical shock and vibration.
The product
is qualified according to the AEC-Q100 standard, includes several advanced self-diagnostic features and is fully ASIL-D (Automotive Safety Integrity Level) compliant.
Murata has more than 20 years of experience of providing inertial sensors for safety critical automotive applications like ESC.
This expertise
has been utilized for the development of the SCHA600 sensor. SCHA600 series features extensive failsafe functions and error bits for diagnostics.
These include internal reference signal monitoring, checksum techniques for verifying communication, and signal saturation/over range detection.
The unique diagnostic feature of Murata’s 3-axis accelerometer
is the continuously operating self-test function, which monitors the sensor during measurement.
This patented self-test function
verifies the proper operation of the entire signal chain from MEMS sensor movement to signal conditioning circuitry for every measurement cycle.
