Murata has developed a new MEMS (Micro-Electro-Mechanical Systems) 6DoF (Six Degrees of Freedom) inertial sensor for autonomous Off-Highway vehicles, dynamic inclination sensing and GNSS positioning support. The sensor enables further advancement in technology and novel solutions for advanced driver / operator assistance systems, autonomous vehicles and GNSS based measurement instruments. The product delivers highest performance available on component level in key parameters like bias stability and noise. Murata calibrates orthogonality of all measurement axes. This allows our customers and system integrators to skip this costly and performance-critical process step.
Murata’s new SCHA63T sensor is the world’s first single package 6DoF component with this level of performance. Traditionally this level of inertial sensor performance has only been available on expensive high-end IMU modules. The sensor can enable centimetre-level accuracy in machine dynamics and position sensing, and can assist ensuring safe, robust and verified designs. One of the key focus areas in product development for SCHA63T has been to ensure operation during high mechanical shock and vibration. Within the same product family, there are also sensor variants qualified according to automotive AEC-Q100 standard. SHCA63T sensor includes several advanced self-diagnostic features and can achieve full compliance with ASIL-D (Automotive Safety Integrity Level).
