    摘要： The push device (2) comprises an annular rotary shoe (4), the internal periphery (15) of which is eccentric with respect to the external periphery (16) and is applied against the back of the rack which is thus pushed towards the teeth of the steering pinion. An anti-backlash mechanism comprises an internally toothed stationary outer ring (3) inside which the shoe (4) is rotatably mounted. The external periphery of the shoe is provided with catching means (17) that co-operate with the notches (6) of the ring (3), with spring means urging the shoe (4) relative to the ring (3). Thus, the catching means (17) co-operate successively with the notches (6) in order to maintain a small clearance between the rack and the pinion.

    摘要： The invention relates to a method for securing the assistance torque (15) supplied by an electric assistance motor (8) in a motor vehicle power steering system, the securing method being characterized in that it includes the steps of: estimating the force on the steering system rack from the torque exerted by the driver on the steering wheel (2), from the assistance torque (15), and optionally from other parameters such as the speed of the electric assistance motor; comparing a target assistance torque with an authorized assistance range, defined with respect to the estimated rack force (17) at any moment, and in the event the target assistance torque is maintained above predefined limits for a predefined duration, correcting and optionally interrupting the power steering.

    摘要： The method consists in: (A) determining in which actual sector (tr_engine) the booster motor is located, a sector of the booster motor being defined by two successive poles; determining a relative angle position (Angle_steerwh_rel) of the steering wheel in relation to the booster motor; (B, C, D) identifying a sector, known as neutral (tr_engine_neutral), in which the booster motor is located when the rotation speeds of the rear wheels, i.e. right (v rear R) and left (v rear L) of the vehicle, are equal; (E) determining an angle offset (angle_offset) of the steering wheel corresponding to a neutral angle position of the steering wheel; determining an absolute angle position (angle_steerwh_absolute) of the steering wheel which is equal to the difference between the relative angle position (angle_steerwh_rel) of the steering wheel and the offset angle (angle_offset) thereof.

    摘要： The invention relates to a power steering system in which the set value for torque or force at the steering wheel is predetermined on the basis of various parameters and information so as to provide the most driving comfort in all conditions of driving the vehicle. The torque or force set value is predetermined on the basis of the sideways acceleration of the vehicle, the acceleration in turn being predetermined mainly from an estimate of the force exerted on the rack, and preferably also predetermined by other methods, with the estimate being weighted among all of the obtained values. Said method is particularly useful for vehicles provided with electrical power steering.
