摘要： A steering wheel angle sensor is described comprising a first part and a second part, wherein the first part and the second part are moveable relative to each other in rotational direction and the first part comprises at least one first signal generating means (1, 2) generating a sine signal (x2, x5) in response to an angular position of the second part and at least one second signal generating means (3, 4) generating a cosine signal (y2, y5) in response to the angular position of the second part. Such a steering wheel angle sensor should allow a simple fault detection. To this end fault detecting means (9) are provided, wherein the fault detecting means (9) form a sum of the square of the sine signal (x2, x5) and the square of the cosine signal (y2, y5) and generates a fault signal, if the sum is not within a predetermined range.

摘要： A hydraulic steering arrangement is described comprising a steering unit (1), a steering wheel and a steering wheel angle sensor (3) detecting an angle of rotation between the steering wheel and the steering unit (1). Such a steering arrangement should have a simple construction. To this end the steering wheel angle sensor (3) comprises a transmitter/receiver arrangement fixed to the steering unit (1) and a target assembly (4) which is rotateably fixed to the steering wheel by means of a connection geometry (9) and comprises a passive reaction arrangement.
