Abstract
A control system for steering a road vehicle having front-wheel and rear-wheel steering, comprising a wheel base l (in m), a rear cornering stiffness c.sub.h (in N/rad), a center of gravity distance l.sub.v (in m) from the front axle and a mass m (in kg) and provided with a decoupled control circuit, a predetermined yaw damping D.sub.G is adjusted according to a damping parameter ##EQU1## via the steering of the rear wheels through an angle .delta..sub.h (in rad). Herewith the yaw rate r (in rad/s), travelling velocity v (in m/s) and steering wheel angle .delta..sub.L (in rad) are measured and the angle .delta..sub.h =(l/v-k.sub.D) (w.sub.h -r) is calculated by a microprocessor, whereby w.sub.h is formed as command variable from the measured steering wheel angle (.delta..sub.L) by a prefilter (F.sub.h) associated with the rear-wheel steering.
