Abstract
A method for checking the tire pressure of a vehicle (1), which vehicle comprises at least one vehicle wheel (3) and a vehicle body (2) which is supported elastically on the vehicle wheel (3). The wheel includes a tire (7), filled with gas, on which wheel the vehicle stands on a subsurface (8). The vehicle body (2) is loaded with an additional mass and thereby the vehicle body is stimulated into a mechanical oscillation (16) relative to the subsurface (8). A response signal (A), that characterizes the mechanical oscillation (16), is measured and analyzed, whereby at least one response value that characterizes the current gas pressure in the tire is determined.

A method for checking tire pressure of a vehicle, which vehicle comprises at least one vehicle wheel and a vehicle body which is supported elastically on the vehicle wheel, the wheel including a tire filled with gas and the vehicle is supported by a subsurface via the tire, the method comprising:
- loading the vehicle body with an additional mass and thereby the vehicle body is stimulated into a mechanical oscillation relative to the subsurface, and
- measuring and analyzing a response signal, that characterizes the mechanical oscillation so that at least one response value that characterizes a current gas pressure in the tire is determined.
