First Claim
1. A method of detecting a pressure loss of a tire in a vehicle equipped with a tire pressure monitoring system, which comprises performing the following steps in a parked state of the vehicle:
- a) deactivating the tire pressure monitoring system having at least one electronic wheel device disposed in a vehicle wheel;
b) activating the tire pressure monitoring system after one of a first defined period of time and upon a vehicle-side request;
c) determining tire-related information of vehicle wheels associated with electronic wheel devices by means of the respective electronic wheel device and generating status signals containing the tire-related information;
d) communicating the status signals to an evaluation device; and
e) returning to the method step (a) at a latest after a second period of time.
