- the piezoelectric elements are arranged in pairs around the steering handle, preferably in segments.
- the free hand recognition is carried out by determining the deflection of the steering column.
- the hands-free detection by means of one or more waves or vibrations of the steering handle or the like. done on the steering handle. - A -
- the waves are optical waves.
- the waves are surface waves.
- the hands-free detection is carried out by determining the electrical conductivity of the surface of the steering handle.
- the free hand recognition takes place by means of a temperature measurement e surface of the steering handle.
- the steering handle has a heater and that at least one metallic component of the heater interacts with the hands-free detection.
- a filament or a hot foil is used as an electrode for a capacitive freehand detection.
- the heater is supplied with a DC voltage and the hands-free detection is supplied with a high-frequency AC voltage and that the electrical connection of the heater to the vehicle ground is electrically isolated.
- T he object is also achieved by a method for detecting a physical quantity on a steering handle, which is characterized in that the change of the physical quantity, in particular the damping, is detected, the entsteh upon exposure of the driver to the steering handle.
- the steering handle or the method is advantageously used in steer-by-wire steering or an IPAS system.

- 4 shows schematically a steering handle, in which a free hand recognition takes place according to surface waves on the steering handle.
- FIG. 5 shows schematically a steering handle with a heating device in which a capacitive free-hand detection takes place.
- FIG. 6 shows a schematic circuit diagram for a steering handle with heating device and capacitive freehand detection.
- a steering wheel is shown as a steering handle, in which a hands-free detection takes place capacitively.
- the steering wheel 1 has a core 2, usually a metal ring, which is screwed to the steering column 4 with a plurality of struts 3.
- the core 2 is covered with a plastic 5.
- another metal body is arranged around the metal ring 2 of the steering wheel 1.
- This can either consist of an electrically conductive metal foil or of an electrically conductive metal fabric.
- the metal body forms a capacity together with the metal ring ⁇ of the steering wheel.
- the dielectric forms the plastic casing 5 of the steering handle.
- the leather coating 7 or a plastic coating is used.
- the steering wheel thus represents a capacitor. This is switched as a capacitive transformer.
- the driver is grounded through contact with the seat, floor and pedals.
- the dielectric of the capacitor is changed by the driver's hand. If the driver has his hand on the steering wheel, he dampens the transmission. This damping is measured and if the damping value falls below a predetermined value, a signal is generated that the driver has no contact with the steering wheel 1.
- Electrode pairs 8, 9 are preferably arranged in the foam around the core 2 of the steering handle 1 as metal bodies. These are connected as differential capacitors. This eliminates malfunctions and temperature influences. ' The human hand changes the dielectric of the differential capacitor, which means that the hand on the steering wheel is recognized.
- a pressure-resistant cable (PST cable) 10 is inserted into the steering wheel. A slight pressure that is exerted on the steering wheel is sensed by the cable 10.
- the hands If the hands are on the steering wheel 1, they exert a lever force F on the steering column 4.
- a sensor 11 which detects the deflection, for example the angle cv Steering column bending, measures, a signal is generated when the deflection falls below a certain limit. It is then recognized that the driver's hands are no longer in contact with the steering wheel.
- Optical free-hand recognition is also provided.
- the outer cover of the steering handle is perforated.
- the figure schematically shows a steering wheel, in which a free hand detection of a contact between the hand of the vehicle driver takes place in accordance with surface waves of the steering handle.
- a circumference of the steering handle is a ring segment 12 made of a hard material.
- a mechanical wave W1 is introduced, which is reflected at the other end.
- the reflected wave W2 is measured. If the reflected wave W2 is severely weakened or no longer exists, the driver has at least one hand on the steering wheel.
- information about the function of the sensor is also available due to the phase shift. If the phase shift is constant, there is no fault.
- a hands-free detection with light waves takes place.
- a non-insulated glass fiber cable is placed around the steering wheel.
- the Light wave is coupled in and reflected at the end.
- the amplitude is weakened by touching the driver's hand.
- the hands-free detection by light waves and surface waves also works if it is not the reflected wave that is measured, but a measurement at the end of the cable or surface waveguide.
- An electrically resistive hands-free detection by means of a steering wheel is also provided.
- the steering wheel is covered with an electrically conductive plastic, which has insulating separators in short sections. Since the driver's hand has a certain electrical conductivity ', two or more parts are electrically bridged. This indicates that the driver has at least one hand on the steering wheel.
- the steering handle has evenly distributed temperature sensors over the circumference. If the sun heats the steering wheel in summer, it is colder where the hands rest. At low vehicle interior temperatures, e.g. in winter, it is warmer where the hands rest. By measuring a temperature difference or a temperature difference, the resting position of the driver's hand is recognized.
- an actuator for example a sinusoidal excitation that is not perceptible to the driver, is applied to the steering column.
- This suggestion is dampened by the hands on the steering wheel.
- This excitation can be read out with a sensitive accelerometer.
- the highest resolution and the lowest susceptibility to environmental influences and disturbances and overall the most reliable free hand detection of even gloved driver's hands is possible with capacitive measurement or with surface waves. These designs are therefore particularly preferred.

- a heating fabric 17 is arranged in a foam covering 16.
- a covering with leather 18 is provided as the outer covering.
- a capacitive free hand recognition is realized according to the invention, in which the knitted fabric 17 of the steering wheel heating is also used for the function of the free hand recognition.
- the metal heaters 17 of the steering handle form an electrode and the steering wheel core 14 forms the counterelectrode - two versions are provided:
- some threads or a film are additionally introduced into the knitted fabric 17 that are not required for heating.
- the knitted fabric is then incorporated into the steering handle, in particular the steering wheel.
- One part of the threads is used for heating, the additional threads or the additional foil used for free hand detection.
- the same metal threads are used for heating and for free-hand detection. While the heating is supplied with DC voltage, the hands-free detection is realized with high-frequency AC voltage pulses.
- the heating mass is galvanically isolated from the vehicle mass.
- the electronic circuit is shown in Fig.6.
