1. A device for correcting the angle of attitude of an automotive vehicle which comprises, in addition to the usual control of the steering of rod wheels of an axle by a steering wheel,means inducing on at least one axle a correction of lock in accordance with parameters representative of the dynamic state of the vehicle and measured by sensors delivering corresponding electric signals,these parameters including instantaneous speed S'"'"' of the vehicle, its angular velocity of yaw θ

  • '"'"' and its lateral acceleration R, andmeans for computing a correcting electric signal from these parameters which is applied to lock correcting means,wherein the improvement comprisessaid means for computing the correcting signal are adapted to develop this signal from a value (e) equal to (R-θ

    '"'"'S'"'"')/S'"'"' or to R-θ

    '"'"'S'"'"' in a manner of an error signal in a closed loop system, tending to reduce the correcting signal to zero by an appropriate control of the lock means.
