to u v according to equation 22 then gives equ20 the subsystem with the state variables r u03b4 v and u03b4 h is then not observable from a v thus a feedback of a v would not have any influence on the dynamics thereof the subsystem is controllable from u h due to the value 1 of the gyro feedback thus its eigenvalues are placed as desired by a state vector feedback the state r which is obtained by a gyro and the variables u03b4 v and u03b4 h which are obtained by front and rear steering angle sensors can be measured and consequently the state vector feedback can be implemented conversely for a given characteristic polynomial p s from equation 43 the state vector feedback required therefor can be obtained as equ22 with the pole placement matrix equ23 in driving tests it must then be determined which position of the eigenvalues of the yaw motion is considered desirable by drivers according to the invention the front steering angle need not be measured on the contrary an electronic integrator is used in the rear wheel steering together with an actuator i e a mechanical integrator a compensator of the second order can thus be construed as illustrated in a block circuit diagram of.
