Electric Power Steering
Motor Control & Angle Sensing
To achieve better fuel efficiency and reduce CO2 emissions, automakers are rapidly migrating from hydraulic to electronically controlled power steering technology. In power steering applications, ams sensors provide: • measurements of the angle of rotation of the steering wheel • measurements for motor control in the power-assisted steering mechanism
BLDC Motor
Motor Control
Position sensors from ams used in electronically commutated motors provide for precise control of torque both at start-up and in operation at speeds as high as 28krpm.

Pedal Position Sensor
Angle Sensing
The ams angle sensor solution for pedal modules is a contactless magnetic position sensor which offers best-in-class automotive safety features. It supports vehicle manufacturers in their efforts to comply with the provisions of the ISO26262 safety standard.
Shift by Wire
In a shift-by-wire application, the mechanical linkage from the gear-change lever to the gears is replaced by electronic control. This means the entire shift-by-wire system is safety-critical, including the angle sensor which measures the position of the lever. To meet the safety requirement, ams supplies a completely redundant position sensor comprising two separate sensor dies in a single compact package, in a stacked-die configuration.
Position Sensing
Automotive-qualified position sensors from ams are ideal for vehicle systems because of their high reliability and performance. Dual-die versions offer full redundancy to guarantee continued operation in the event of the failure of one die. The automotive functional safety process implemented by ams increases system reliability and makes ams devices easy to integrate into vehicle subsystems.
Rotary Magnetic Position Sensors
Motor Control
The accurate angle measurements produced by ams position sensors in electronically commutated motors improve the control of torque at start-up and in high-speed operation. Effective torque control provides for more efficient motor operation, and reduces vibration and other forms of mechanical interference caused by torque ripple.
