摘要： In a vehicle, apparatus, and method for damping a steering system, which is assisted by a motor of the vehicle, and in which the motor assists a driver of the vehicle in moving a toothed rack of the steering system in a motor mode of the motor and the motor is rotated in a generator mode of the motor by a movement of the toothed rack, a speed of the motor is determined. The damping is performed if the speed exceeds a first threshold value and the motor is operating as a generator, and the damping is suppressed if the motor is operating as a motor or the speed falls below the first threshold value or a second threshold value.

摘要： A method for operating an electrical power steering system of a transportation vehicle wherein a steering wheel angle is pre-defined by a steering wheel as a measure for a desired wheel steering angle for at least one steerable wheel of the transportation vehicle, where an electrical power drive with an electric motor provides a steering support, and where a support torque of the steering support is reduced based on a damping function in response to the combustion engine of the transportation vehicle being started. Also disclosed is an associated electrical power steering system, to a computer program, and to a control appliance.
