Abstract
A method and a monitoring unit for monitoring a tire of a vehicle record a first measured value of revolutions of a tire with a first sensor. In addition, a second measured value of the revolutions of a tire is recorded with a second sensor. Alternatively, a second measured value of a second, different measured variable of a tire can also be recorded. In a further step, the directly measured or derived measured values of a measured variable are compared and an error signal is generated if a determined deviation is greater than a predefinable tolerance value.

11. A method for monitoring a tire of a vehicle, the method comprising the following steps:
-
a) recording a first measured value of revolutions of the tire with a first sensor; b) recording a second measured value of the revolutions of the tire or a second measured value of a second, different measured variable of the tire with a second sensor; c) determining a deviation by comparing the first measured value with the second measured value or comparing the second measured value with a value of the second measured variable derived from the first measured value or comparing a value of a third measured variable of the tire derived from the second measured value with a value of the third measured variable derived from the first measured value; and d) generating an error signal if the determined deviation is greater than a predefinable tolerance value. - View Dependent Claims (12, 13, 14, 15)
