摘要： Apparatus and method for damping a steering movement in an active steering system of a vehicle, wherein a variable is determined which characterizes a force acting from outside the vehicle on the steering movement of the active steering system or a moment acting from outside the vehicle on the steering movement of the active steering system that has an accelerating effect on the steering movement of the steering system. The speed of the steering movement is limited as a function of the variable. Vehicle comprising said apparatus.

摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include an electric motor having a motor shaft. The motor shaft drives a spindle of a worm gear, and the worm gear comprises a spindle nut in such a manner that a rotational movement originating from the motor shaft is converted into a linear movement of the spindle nut along an axis. The spindle nut, for purposes of steering wheels of the motor vehicle, is connected to at least one tie rod. The worm gear may be a ball screw drive, a trapezoidal drive, or a roller screw drive.

摘要： A method is provided for operating an actuator of a steer-by-wire steering system of a motor vehicle at speeds from a standstill up to parking and/or maneuvering speeds. The method includes detecting an instantaneous steering angle of at least one wheel on an axle of the motor vehicle, detecting a steering angle demand, determining a limit value of an acceleration of a drive mechanism of the actuator at least as a function of the instantaneous steering angle, and activating the actuator for setting a steering angle of at least one wheel as a function of the steering angle demand and using the limit value of the acceleration.

摘要： The present embodiments may provide a steer-by-wire type steering apparatus which can significantly reduce production cost by reducing the number of components and simplifying the assembly procedure, by eliminating a pinion gear, etc., and sensing the position of a sliding bar on the basis of rotation information detected from a gear box which transfers the rotational force of a motor to the sliding bar.

摘要： A steering control including a steering column, a hub fixedly connected to the steering column, and a support member fixedly connected to the hub. The support member has a continuous outer surface including a central point. A steering member is moveably mounted upon the support member and a steering module is mounted in the support member. The steering module converts movement of the steering member relative to the support member into a steering position signal.
