Abstract
This method with associated device serves for generating an actuating signal for the rotation of a coach body in a track curve-dependent manner, the said body being fastened to the chassis of a rail vehicle so as to rotate about its longitudinal axis. Measuring signals are used for the vehicle velocity v, the angular speed omega of the chassis about its longitudinal axis and the transverse acceleration b. The latter is fed to a first low-pass filter 4. In order to match the actuation signal to the real conditions of the rail as far as possible it is proposed to feed the measuring signal for the angular speed omega to a second low-pass filter 5 and to multiply its output signal in a multiplying element 6 by a signal dependent on the square of the vehicle velocity v. The actuation signal is then formed in a summation element 7 from the output signals of the first low-pass filter 4 and of the multiplying element 6. The acceleration due to gravity g is also included in the velocity-dependent signal for the multiplying element 6 in accordance with (v<2>/c-g). For the outputting of the actuation signal, other lower limit values epsilon 1 are provided for the angular speed omega and epsilon 2 for the angle phi of the camber of the track.
