Automotive position sensors

Position Sensing

Contactless position sensors from ams offer best-in-class stray field immunity and superior durability, and they comply with the requirements of the most stringent safety standards.

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

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.

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.

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.
