Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
Steering handle for motor vehicles comprising: a core; a secondary metal about the core; a dielectric material between said core and said secondary metal such that a capacitor is defined thereby; means for monitoring a capacitance of the capacitor and determining a contact between at least one hand of the driver and the steering handle based on the monitored capacitance; and a second secondary metal about the core and configured such that the secondary metal and the second secondary metal define a differential capacitor.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
Steering handle for motor vehicles according to claim 1 , wherein the steering handle is provided with a capacitive free hand recognition.
Claim 4
Dependent Claim
26 words
Steering handle for motor vehicles according to claim 1 , wherein damping of the monitored capacitance is identified when the driver acts upon the steering handle.
Claim 5
Dependent Claim
32 words
Steering handle for motor vehicles according to claim 1 , wherein the change of capacitance, in particular its damping, is recorded which is caused by the driver acting upon the steering handle.
Claim 6
Dependent Claim
20 words
Steer-by-wire steering system for a motor vehicle, wherein it is provided with a steering handle according to claim 1 .
Claim 7
Dependent Claim
28 words
Steering system for a motor vehicle on which a steering torque is actively applied (IPAS), wherein it is provided with a steering handle according to claim 1 .
