Abstract:
A vehicle having at least four wheels which are arranged on two axles, can be cushioned relative to a body of the vehicle in the direction of a vertical axis of the body and are provided with inflatable tires, and having a tire pressure alarm system comprising:at least four position generators, one such position generator being assigned to each wheel;signals from said position generators providing an indication of respective vertical distances between an associated wheel center and a body of the vehicle; anda control unit which is coupled to receive signals from said position generators, and which is programmed to determine for each wheel a time-related mean values for said vertical distance;determine from the mean values of three wheels on two axles, a desired center position of a fourth wheel; anddetermine that an unequal tire pressure exists if an actual center position of said fourth wheel deviates by more than a given tolerance from the desired value; andgenerate an alarm in response to a determination that unequal tire pressure exists.
