MEMS sensors ensure automotive "active safety"

Murata, which has always pursued innovation, expanded its MEMS sensor products by acquiring the Finnish MEMS giant VTI in 2012. The application in the field of automotive electronics is mainly reflected in the early prevention of accidents in the driving process of automobiles, that is, "active safety."

Murata's MEMS sensors are widely used in ASB (Brake Anti-lock Braking System), ESC (Electronic Stability Control System), ECS (Electric Control Suspension), EPB (Electric Hand Brake), HAS (Ramp Start Assistance), TMPS (Tire Pressure Monitoring) ), engine anti-shake, vehicle inclination measurement, in-vehicle heartbeat detection, etc. Compared with “passive safety” after accidents such as “airbags”, Murata’s MEMS sensors rely on their extremely high sensitivity and safety performance to “prevent problems before they occur”.

Cui Wei Murata, senior engineer in the Market & Business Development Department of Murata (China) Investment Co., Ltd., accelerometers, gyro sensors for preventing rollover, pressure sensors, sensors for tire pressure detection, and their combined sensors. In the car's active safety design, it has contributed. These sensors are AEC-Q100 compliant, featuring high accuracy, high stability, and high reliability, especially in the field of automotive electronic stability systems (ESC). Murata MEMS sensor In April of this year, Murata produced a new automotive-grade three-axis accelerometer SCC3300, which has a comprehensive improvement in performance compared to the old SCC3100, such as zero offset stability, noise, and linearity. Degree, vibration resistance, impact resistance, etc., high performance and high reliability in harsh environments. While focusing on traditional automotive safety applications, Murata is also focusing on emerging areas such as Advanced Auxiliary Driving Systems (ADAS) and future unmanned driving. Murata's MEMS sensors are also at the forefront of the industry and technology in advanced driver assistance systems (ADAS), namely front vehicle collision alarms, blind spot monitoring, lane departure warnings and automatic parking. It is worth mentioning that sensor technology, as a support for autonomous driving technology, opens up new areas for safe driving. Murata Acceleration and Gyro Combination Sensors In order to ensure the safety of driverless cars, laser radar, 24G, 77Ghz millimeter wave radar, vision technology cameras, ultrasonic radar and other high-tech will be applied to the car, it can be said that the future Driverlessness is a multi-sensor fusion and collaboration process, which must have MEMS sensors. Judging from the current situation, the IMU (Inertial Measurement Unit) can be used as a judgment of the vehicle's own attitude and contributes to future high-precision positioning. At the same time, for GPS signal loss or blocking (such as tunnels, placed in high-rise buildings), MEMS sensor-based IMU can provide reliable information for the car brain while being redundant. In the future, Murata will continue to devote itself to MEMS technology, constantly challenge new heights, and provide high-precision, high-reliability products for the automotive electronics market in terms of “safety”, “interconnection” and “pre-prevention”. Safer and smarter, make our lives more comfortable and more secure.
