    • PROBLEM TO BE SOLVED: To provide a control system for a vehicle regarding the vehicle consisting of a traction vehicle and a trailer.
      SOLUTION: The traction vehicle is provided with an electronically operable drive transmission system 20 regarding the control system for the vehicle consisting of the traction vehicle and the trailer. A driver inputs a trailer setting steering angle (ALW-SOLL) through a trailer steering angle setting value sensor 32. A modified traction vehicle setting steering angle (ALW-SOLL') of an axle having the purpose steering the traction vehicle is determined from the actual steering angle (ALW-IST) of the trailer and the trailer setting steering (ALW-SOLL) to simplify the reverse of the vehicle. In the operation state of the reversing device, the reversing device 30 changing the actual steering angle (ALW-IST) of the trailer into the trailer setting steering angle (ALW-SOLL) is provided in processing of a modified movement vector (BV') when the vehicle moves by taking over from the current traction vehicle setting steering angle (ZLW-SOLL) within the modified movement vector (BV').

    • The invention relates to a device and a method for the early recognition and prediction of unit damage in machine plants, in particular mobile machine plants. The structural noise of the machine plant is thus recorded by a sensor (1), transmitted as an acceleration signal and analysed in a digital signal processor (DSP). In order to inhibit negative influences from environmental vibrations or structural sound waves which are nothing to do with the status of the machine plant, the acceleration signal is firstly transformed into the frequency domain by means of a fast Fourier transformation and the data thus obtained is then transformed back into the time domain by means of a cepstrum analysis, such that resonance data from single shock impulses (a cepstrum) are obtained in the time domain. Said cepstrum is then compared with a comparative cepstrum, available in a memory unit corresponding to load and speed signals for the current operating status for a new machine plant. On exceeding threshold values the diagnostic signal, in particular information about the unit diagnosed as being damaged and the predicted remaining service life thereof is displayed for the user and an emergency operation initiated.
