True-Power-On Steering Angle Sensor with Revolution Counter

摘要

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° in a vehicle, comprising—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—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.

1. A steering angle sensor for detecting a steering angle of a steering column over a range of angles greater than 360° in a vehicle, comprising:
a transmitter element for stimulating a transmitter field and a measuring sensor for stimulating an output signal depending on reception of the transmitter field, wherein the measuring sensor and the transmitter element are disposed so that the transmitter field received by the measuring sensor is dependent on the angle of rotation of the steering column that is to be detected, and a counting element with a non-volatile memory for counting and outputting a number of revolutions of the transmitter filed relative to a reference angle of rotation.
