A power steering system for use in a land vehicle with separately driven steerable wheels (30). Servo-control is produced by creating a differential torque by means of motors (40). The servo-control is provided when a torque is applied to the steering wheel (10), by generating a differential torque through the motors (40) to create servo-control forces due to virtual lever arms (39) defined between the centre of traction (34) of each wheel (30) and the imaginary intersection between the ground and a virtual extension of the steering axis (32) of the wheel (30).
Une servodirection utilisée dans un véhicule terrestre dont les roues directionnelles (30) sont motrices de façon indépendante. Un asservissement est produit en créant un couple différentiel à l'aide des moteurs (40). L'asservissement est fourni lorsqu'un couple est appliqué au volant (10), en générant le couple différentiel par les moteurs (40) de façon à créer des forces d'asservissement à cause de bras de levier virtuel (39) définis entre le centre de traction (34) de chaque roue (30) et l'intersection imaginaire avec le sol d'une prolongation virtuelle de l'axe d'orientation (32) de la roue (30).
