Abstract: A method for determining non-directly measurable driving status variables of a vehicle reads in by a sensor device and transmits to a computing device the following: wheel speed of each vehicle wheel, steering angle of the vehicle, yaw angle rate, longitudinal road inclination of the vehicle, transverse road inclination of the vehicle. Driving status variables are calculated by the computing device with a computational model, so that further driving variables that are difficult to measure or not directly measurable can be determined on the basis of the calculated driving status variables. The calculated and determined variables are transmitted to an actuator device to control and/or regulate the vehicle. The computational model contains a vehicle model, a tire model, and a wheel suspension model and are solved together in the computing device according to the following differential equation system: ( M F + ? i = 1 n ? 3 M Ri ) ? q .

Abstract: A vulcanizable elastomeric composition and a method of forming said composition is presented. The method generally comprises the mixing of sulfur and an ultra-accelerator into a mixture of an elastomeric polymer matrix, fillers, and silane coupling agent during the silanization reaction step, prior to the occurrence of vulcanization. The addition of the ultra-accelerator, such as TBzTD, enhances the efficiency of the silanization reaction and forms at least one bond with the elastomeric polymer matrix. The silanization reaction step may comprise multiple mixing substeps in which the ultra-accelerator may be incorporated into the elastomeric composition.
