Publication number: 20080294355Abstract: A method for calculation of the lateral force in a motor vehicle with an electromechanical or electrohydraulic steering system is disclosed. The method comprises the following steps: firstly a steering column force is recorded, from which a total restoring torque is calculated. The total restoring torque comprises restoring torques generated by differing forces acting on the wheels. Said restoring torques include a restoring torque generated by lateral force and other restoring torques. The other restoring torques are quantitatively determined on the basis of measured values and subtracted from the total restoring torque, in order to determine the restoring torque generated by lateral force. Finally the lateral force is determined from the restoring torque generated by the lateral force.Type: ApplicationFiled: March 23, 2005Publication date: November 27, 2008Inventors: Thomas Berthold, Ralf Schwarz, Stefan Fritz

Publication number: 20080269974Abstract: Disclosed is a method of controlling the driving dynamics of a vehicle, in which a nominal value ({dot over (?)}ref) of a driving state variable that corresponds to a preset driver input is compared with a detected actual value ({dot over (?)}) of the driving state variable, and in which a rolling moment distribution is detected and modified. The method is implemented in such a manner that the driving performance of the vehicle is determined by comparing the nominal value ({dot over (?)}ref) of the driving state variable with the actual value ({dot over (?)}) of the driving state variable. Also, depending on the determined driving performance, a new rolling moment distribution is determined which corresponds to a predefined driving performance and the new rolling moment distribution is adjusted.Type: ApplicationFiled: March 9, 2005Publication date: October 30, 2008Applicant: Continental Teves AG &Co. oHGInventors: Ralf Schwarz, Thomas Raste, Steffen Troster, Matthias Muntu
