Based on the inductive sensor technology, these sensors measure the coupling between an excitation coil (TX) and two receiver coils (RX) via a rotating target. The coils are executed as printed circuit coils and the rotating target is a simple punched metal part. With the correct layout of the coils and the target, both synchronized to the number of pole-pair count of the motor, the IC output is proportional to the electrical angular position within one pole-pair segment with increased resolution and high performance of only 0.3° electrical INL!

Due to its flexibility, easy adaption and low overall system costs, these products act as the perfect resolver replacement and can be used for on-axis as well off-axis applications!

ams Automotive Solutions

As the world is becoming more and more connected, so are vehicles.


The challenge today is to enhance the process of travelling,
to make automobile traffic smarter, safer, more comfortable and even greener.

Angle sensing and motor control

Highly accurate, robust and reliable, compact position sensors from ams are an ideal fit for automotive angle and rotary position sensing applications.

ams automotive angle sensors are widely used for sensing the angle of the accelerator and brake pedals, and the position of gear shifters and chassis.

Dedicated rotary position sensors for motor control are also ideal for automotive uses, such as the pump motors in electric power steering and transmission system motors. The number of electric and hybrid electric vehicles on the road is also set to grow at a rapid rate. Here, the ams motor control sensor portfolio offers high accuracy at high rotation speeds, while remaining inherently immune to the external magnetic fields induced by the high currents flowing through the motor.

LiDAR solutions for autonomous vehicles

The move to equip vehicles with increasingly sophisticated driver assistance systems, and eventually to make the vehicle fully autonomous, requires a combination of object detection and imaging sensors. By combining radar detectors, cameras and optical depth sensing systems such as LiDAR, a vehicle can capture a detailed, real-time view of the space around it, while building in redundancy to protect against the failure of any one sensor.

For LiDAR systems, the VCSEL arrays and VCSEL driver technology from ams provide high-power light sources that operate extremely reliably over a broad temperature range.

Projection Lighting

Micro Lens Array (MLA) projection technology from ams enables automotive manufacturers to implement compact, small-footprint projection lighting which can cast bright and crisp images on to flat surfaces. Featuring inherently extended focal lengths, MLA Projected Lighting devices can cast images on a variety of surfaces and over long focal distances, making them ideal for both exterior body lighting and interior lighting.

Future applications include decorative lighting for cars' exterior and interior, but also safety lighting, such as an additional brake light or back up guide lamp, helping to raise awareness of other traffic participants about actions this vehicle is taking. With upcoming autonomy of cars, this will also become ever more important to show when a vehicle is in autonomous mode.

Driver monitoring and identification systems

In all but fully autonomous vehicles (classified as ‘Level 5’ autonomy), the driver’s ability to take back control of the vehicle must be monitored continuously. For this function, 3D optical sensing is already in use in vehicles to create depth maps which reveal the driver’s posture, and show where the driver is looking – data which can be used to determine their state of readiness to assume control of the vehicle. 3D sensing can also be used for driver identification and access control.

3D sensing solutions in use today and under development make use of ams technologies such as time-to-digital converters for time-of-flight measurement, and illumination solutions for structured light and adapted stereo vision systems.

High-precision sensing for automotive battery packs

Electric vehicles need to measure very precisely the traction battery’s state of charge and state of health in order to make an accurate estimate of the vehicle’s range

Shunt resistor-based, zero-offset battery sensing solutions from ams enable automotive battery management systems to make the very accurate current and voltage measurements which are required in this application.
