The invention relates to a device for determining the steering wheel angle, comprising an angle sensor (10) which measures, in a precise manner, the corresponding angle range in at least one full rotation of the steering wheel (9) with a first accuracy; an incremental measuring angle sensor (11) which emits a first output signal which enables a modification of the angle position of the steering wheel (9) to be determined with a second accuracy which is greater than the first accuracy, and which emits a second output signal when the steering wheel (9) takes up at least one predetermined position which is assigned to at least two reference steering wheel angles, and an evaluation unit (12) which is connected to the angle sensors (10, 11). The evaluation unit (12) determines the steering wheel angle from an output value determined by means of a precisely measuring angle sensor (10), in accordance with the first output signal of the incremental measuring steering wheel angle (11). The evaluation device (12) adapts the value of the steering wheel angle to one of the reference steering wheel angles when the second output signal appears. The invention also relates to a method for determining the steering wheel angle.

The invention relates to a motor vehicle brake consisting of at least one brake disk or at least one brake drum, at least two brake linings and a device for determining a tension force acting upon the brake linings when the motor vehicle brake is actuated. The brake linings comprise a carrier plate (1) and a friction layer (2) which engages with the brake disk or brake drum. In order to measure the tension forces arising from the actuation of the brake in a sufficiently accurate, low-cost manner, the device for determining the tension force is configured in such a way that it detects modifications of the electric resistance (3) of the friction layer occurring during actuation of the motor vehicle brake and evaluates them in order to detect the tension force.

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 (d T ) 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 (d H,O ) recorded and stored essentially simultaneously with a previous switching off of the steering system and the total steering angle (d T,0 ) and the steering wheel angle (d H ) determined essentially simultaneously with a switching on of the steering system by means of the steering wheel angle transducer (130).
