Steering angle sensors

The angle sensors for absolute steering angle measure-

ment are available as a single-sensor SMD package for

conventional designs, which achieve the ASIL D rating via a

plausibility calculation of the two angle sensor signals as a

result of a significant movement of the steering wheel.

Infineon angle sensors support steering angle sensor con-

figurations with an on-board microcontroller, as well as sat-

ellite sensor designs, due to a broad variety of supported

communication interfaces. In particular, the SPC interface

allows the connection of angle sensor(s) and linear Hall

The sensors are also available in dual-sensor packages

for module designs, that support an ASIL D-rated steering

angle directly at power-on (ASIL D from start).

sensor(s) on a bus line in combined Torque-Angle-Sensor

(TAS) modules. Compared to conventional designs with

separate torque sensor and angle sensor modules, this

configuration reduces the cost of wiring and saves module

space.
