The invention relates to a device for measuring the steering rack path of a motor vehicle steering system, which has a steering actuation device and a steering rack actively connected thereto. Said steering rack can be displaced in an essentially linear manner and pivots the wheels into a desired position via additional elements such as a steering tie rod and a steering knuckle arm. One or more field-producing means are provided in the vicinity of the steering rack, the material thereof consists of a plastic-bonded permanent-magnetic material, and has/have a course of the magnetic field line and/or course of the magnetic field intensity according to the Nonius principle. In addition, at least one sensor module is mounted in a fixed manner next to the steering rack, has at least one magnetic field sensor and at least one sensor switching circuit, and transforms the course of the magnetic field line or course of the magnetic field intensity into output signals, which can be processed further and which indicate a linear path change or the position of the steering rack in the direction of its longitudinal axis.

摘要:
A method for determining the absolute position of a linear actuator is described. In the process, the rotational angle position of the rotor of the corresponding electric motor of the linear actuator is determined by a first sensor. In addition, the rotary angle position of a transmitter wheel of a second sensor coupled to the rotor is determined by means of a special transmission ratio. The absolute position of the linear actuator is derived from the differential value of the determined rotary angle positions. The method can be implemented in a simple and inexpensive manner.

The invention relates to a method for determination of a steering angle in a steering system, provided with a superimposed gear, operated by an actuator, by means of which a total steering angle on a steering gear output side part of the steering column at the gear output side, composed of a steering gear input side adjusted steering wheel angle and an additional steering angle as controlled by the actuator may be adjusted, whereby with the steering system switched off the actuator motor is locked and the steering wheel angle is determined by a steering wheel angle transducer arranged on the input side of the steering gear. According to the invention, the method is characterised in that the total steering angle (δT) is determined by an incrementally-measuring steering angle transducer (132), arranged on the gear output side on the steering column, starting from an initial value, whereby the initial value on switching on the system is determined from a value for the steering wheel angle (δH,O) recorded and stored essentially simultaneously with a previous switching off of the steering system and the total steering angle (δT,0) and the steering wheel angle (δH) determined essentially simultaneously with a switching on of the steering system by means of the steering wheel angle transducer (130).
