Abstract: A method for determining the tread depth of a vehicle tire, with the tire being mounted on a vehicle, the tire being rolled over or placed on a measuring station, the tread of the tire being optically sensed transversely to the rolling direction of the tire on at least one measuring line, a ray fan extending from a light source being reflected at the tire surface and a signal of the reflected ray fan being recorded by a sensor, and the signal of the reflected ray fan being evaluated by way of a triangulation method, is characterized in that the signal is recorded in a non-orthogonal manner to the tire surface.

Abstract: A method for automatically identifying a type of vehicle on a test stand includes: a) supplying predetermined parameters characterizing the type of vehicle; b) providing a test stand encompassing a plurality of sensors; c) sensing at least some areas of a tire on the test stand; and d) determining at least one tire property from values sensed by means of at least some of the sensors. The properties determined in step d) are compared with the predetermined parameters, and the type of vehicle is assigned on that basis, or parameters of a new type of vehicle are defined if the properties fail to match the parameters.

Abstract: A method for ascertaining the pressure and the profile depth in a pneumatic vehicle tire which is fitted to a vehicle, wherein the pressure is detected with the aid of an arrangement comprising load sensors, which arrangement supplies force signals for a two-dimensional pattern of the force distribution which is exerted by the vehicle tire in contact with the sensors when the vehicle moves over the arrangement, wherein the tire pressure is determined from the force distribution independently of the method of manufacture or the model of the tire and of the vehicle, is characterized in that the profile depth of the tire is determined before, while or after the pressure is determined.

Abstract: A system for detecting the pressure in a pneumatic vehicle tire which is mounted on a vehicle and/or the speed of the vehicle, having an arrangement composed of load sensors which supplies force signals for a two-dimensional pattern of the distribution of force which is exerted by the vehicle tire in contact with the sensors when the vehicle moves over the arrangement, a computer which is programmed in such a way that it defines the tire pressure and/or the speed on the basis of the distribution of force independently of the method of manufacture or the model of the tire and of the vehicle, and a device for displaying the pressure and/or the speed, is characterized in that the arrangement composed of load sensors comprises at least two series of load sensors which are arranged one behind the other in the direction of travel, wherein at least one row of load sensors is offset with respect to one or more rows of the load sensors by a predetermined absolute value transversely with respect to the direction of tra
