The invention relates to a steering angle sensor for detecting a steering angle of a steering column over an angular range of more than 360&#xb0; in a vehicle, comprising&#x2014;a transmitter element for exciting a transmitter field and a measuring sensor for exciting an output signal dependent on a reception of the transmitter field, wherein the measuring sensor and the transmitter element are arranged such that the transmitter field received by the measuring sensor is dependent on the steering column rotational angle to be detected, and&#x2014;a counter element with a non-volatile storage unit for counting and outputting a number of revolutions of the transmitter field with respect to a reference rotational angle.

True-Power-On steering angle sensor with revolution counter

A steering angle sensor system for measuring a steering angle in a motor vehicle. The steering angle sensor system includes a magnetic encoder which is coupled to at least one magnetic field sensor that senses a variation in the steering angle even when the ignition is switched off, and an electronic memory for storing the steering angle variation. The steering angle sensor system also includes at least one magnetic-field-sensitive element which is coupled to the magnetic encoder for detecting the occurrence of steering movements at an early time in order to at least partially activate the steering angle sensor system and/or another system.
