Produkt-Übersicht
We provide Automotive MEMS sensors which have reliability testing performed according to AEC–­Q100 and provide PPAP and qualification data upon request. These are designed or specifically qualified and tested for the Automotive market with those unique needs in mind. These support the rapid growth of convenience, infotainment, telematics, Advanced Driver Assistance Systems ­(ADAS), and other technological features for the Automobile.

Automotive Applications

Table 1 : Applications

Dead Reckoning

Vehicle To Vehicle Location

Vision Systems

Augmented Reality HUD

High performance 6-axis IMUs enhance positioning systems when GPS/GNSS signal is not available or reliable. Gyroscope and accelerometer outputs are fused to determine vehicle position even in multi-level parking or tunnels.

The accelerometer and gyroscope data fusion provides incredibly accurate location data for Vehicle to Vehicle systems and infrastructure.

6-axis IMUs enable camera image stabilization to compensate for road vibrations, allowing crisp and stable rear view image in electronic mirrors.

High performance 6-axis IMUs enable overlay projection stabilization, significantly increasing driver's awareness of surroundings.

Telematics

Lift Gate Control

In-Vehicle Infotainment

Smart Antenna

The accelerometer enables crash detection which can trigger emergency calls, and the gyroscope allows for vehicle positioning and driving style analysis.

Door control systems use accelerometer and gyroscope sensors to monitor doors dynamic conditions during automatic movement.

6-axis IMU sensors enable advanced features and deliver a superior user navigation experience.

6-axis IMUs in combination with GNSS enables local positioning computing, simplifying smart antenna installation as it requires only a power connection.
