Claim 10:
11. A method for determining a rotational speed of at least one wheel of a vehicle, the method comprising:
detecting, via a detection device of an apparatus, an angular velocity of the wheel that is correlated to the rotational speed making use of the detection device to provide an electrical detection signal depending on the angular velocity detected, wherein the apparatus includes the detection device, a first control unit with a first measurement device for measuring the detection signal, the first control unit being electrically joined to the detection device, and a second control unit with a second measurement device for measuring the detection signal, the second control unit being electrically joined to the detection device, the detection device being electrically switchable or is electrically switched between the first measurement device and the second measurement device; and
measuring the detection signal making use of the first control unit when the first control unit is operating without fault, making use of the second control unit when the second control unit is operating without fault, and making use of the first control unit and the second control unit when the first control unit and the second control unit are operating without fault to determine the rotational speed;
wherein the first control unit and the second control unit are connected via at least one electrical wire and a separate connection from the detection device to each of the first and second control units.
