1. A method for monitoring a wheel parameter of a wheel using a monitoring device, the monitoring device containing a power supply having an energy converter for converting kinetic energy from the wheel into operating power for wheel electronics, and a transmission unit for transmitting the wheel parameter to an evaluation unit, which comprises the steps of:
- reading out and transmitting the wheel parameter to the evaluation unit at a transmission time, for which the power has been provided by the power supply;
calculating a predicted time of transmission in the evaluation unit with help from at least one dynamic performance parameter and a model of the power supply, the model being stored in a memory of the evaluation unit;
comparing the predicted time of transmission and an actual transmission time; and
emitting an alarm signal if a difference is detected between the predicted time of transmission and the actual transmission time or if an absence of a transmission is detected.

9. A monitoring system for monitoring a wheel parameter of a wheel, the monitoring system comprising:
-
an evaluation unit; and a monitoring device, containing; a power supply having an energy converter for converting kinetic energy from the wheel into operating power for said monitoring device; and a transmission unit for transmitting the wheel parameter to said evaluation unit at defined transmission times; said evaluation unit having a computing unit, a data memory and an input/output unit, said evaluation unit being programmed to; calculate at least one predicted time of transmission of the wheel parameter on a basis of at least one dynamic performance parameter and a model of said power supply, the model being stored in said data memory; compare the predicted time of transmission with at least one actual transmission time, such that a comparison value thus obtained allows conclusions to be drawn concerning a functional status of said monitoring device; and emit an alarm signal in response to a comparison result. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
