    • The tire pressure sensor (13) for monitoring vehicle tires is fastened radically relative to the wheel axis at the circumference of a wheel rim and includes a reference pressure chamber (20) with a contact pin (22) which cooperates with an electrically conductive diaphragm (21) closing the reference pressure chamber (20) toward the tire. An added mass (30) is fastened freely at the diaphragm center for raising the switching threshold of the tire pressure sensor (13) as a function of speed and is dimensioned in such a way that the switching threshold is raised by a desired pressure differential (.DELTA.p) relative to the switching threshold p.sub.o at standstill at a predetermined radius r of the diaphragm (21), a predetermined rotational radius R of the diaphragm (21) and a predetermined rotational speed v of the diaphragm (21). The required added mass (m) results from the equation m=f(.DELTA.p, r.sup.2, R, v.sup.2), advantageously m=(.pi./4)r.sup.2 {[R/v.sup.2 ].DELTA.p - p.a}k wherein p is the material density of the diaphragm, a is the diaphragm thickness and the factor k is between 1.1 and 1.5.

    • A method is described for determining the wheel speed during braking of a vehicle having in addition to at least one wheel with speed sensor at least one further wheel without speed sensor and means for determining the braking pressure. For this purpose, the braking operation is subdivided into several time intervals during which the relative value from the braking energy and the kinetic energy of the vehicle are obtained, and the contribution of the wheels without speed sensors to the braking energy is defined during a first time interval. Furthermore, the ratio of the relative value in this time interval to the relative values in further time intervals is formed, and the mean value for the wheel speed of all wheels without speed sensors is ascertained in the further time intervals from the ratio of the relative values.
