Smart Cockpit based on ST ASM330LHH MEMS Sensor series Solution

With the development of automobile assisted driving and driverless driving, inertial navigation has increasingly become an indispensable technical requirement. Under the dense high-rise buildings, complex elevated buildings, and lengthy underground tunnels in the city, GPS signals are blocked and interfered, making it unable to provide navigation services. At this time, high-precision inertial navigation can make up for the loss of GPS signals and ensure normal navigation itineraries.

The core of the inertial navigation IMU is an inertial sensor. When the inertial navigation IMU is installed on a vehicle, it can calculate the vehicle's displacement and azimuth angle by measuring the acceleration and angular velocity of the vehicle's movement. It can fill the gap of GPS signal loss, provide high-precision positioning for vehicles, and ensure vehicle driving safety.

ST's automotive-grade six-axis inertial sensor ASM330LHH series provides ultra-high-resolution motion tracking functions for advanced vehicle navigation and information service systems. The ASM330LHH series can meet the continuity and accuracy requirements of vehicle positioning by inertial navigation.

When satellite signals are blocked, the ASM330LHH series can provide sensor data for advanced dead reckoning algorithms to calculate the precise position of the car. The advanced low-noise, temperature-stable design of the ASM330LHH series enables reliable in-vehicle information services and can also meet the needs of advanced autonomous driving systems.
