Abstract
A sensor for measurement of yawing motion, pitching or rolling motion, particularly as suited for use in motor vehicle control systems, contains an annular hollow object (1, 2, 4) in which a magnetic fluid (MF) is located. The magnetic fluid is set into rotation by an electromagnetic field and serves as the rotating mass of the sensor. The measuring signal is obtained by measuring the forces (F) acting on the rotating mass or by generating compensation fields.
Claims8
Sensor for measurement of an angular motion, comprising:
- a rotating mass that is connected to a body, the rotating mass being a magnetic fluid that is located in a ring-like hollow space and that is rotated around a rotational axis by an electromagnetic field;
- and
- equipment for measuring and analyzing forces acting on the rotating mass.
A method of installing a sensor with a magnetic fluid that is rotated around a ring-like hollow space about a rotational axis by an electromagnetic field for measuring an angular motion in a vehicle, including the steps of:
- arranging the sensor in proximity to the center of gravity of the vehicle;
- orienting the sensor in such a way that a rotational plane of the magnetic fluid approximately runs perpendicular to the plane of the angular motion to be measured;
- and
- connecting the sensor to the vehicle.
