A method for controlling an active rear axle steering of a motor vehicle when steering out from straight travel with given actual dynamics of the wheel guidance of the motor vehicle, wherein an actual steering signal of the motor vehicle is received by a control circuit from at least one sensor, then from the actual steering signal a dynamic model of the wheel guidance calculates a time variation of a differential signal describing a deviation of the actual steering signal from an imaginary nominal steering signal which would be needed in order to perform the steering with a given nominal dynamics, and from the differential signal a predetermined conversion rule is used to generate a nominal steering signal for the rear axle steering and the rear axle steering is actuated with this.

In an electric power steering device which controls an assist motor such that a turning angle of turning wheels approaches a target turning angle set corresponding to steering torque based on an operation of a steering wheel by a driver, pure steering torque is calculated by correcting detection steering torque detected by a torque sensor based on a steering angle detected by a steering angle sensor, and a target turning angle is set based on this pure steering torque. Thereby, influence of moment of inertia and viscous friction of a constituent member on an upstream side of the torque sensor in a steering mechanism, etc. is eliminated, and a correct target turning angle is set. As a result, the turning angle can accurately correspond to the operation of the steering wheel by the driver to attain good drivability.

A steering column assembly is disclosed that comprises: an elongate rotatable steering column, a displacement motor, a torque feedback motor; an engagement mechanism and a control.

The displacement motor displaces the steering column between the stowed and deployed positions. The torque feedback motor is connected to the steering column and by which the steering column is rotatable. The engagement mechanism is engaged when the steering column is in the stowed position and limits the angular displacement of the steering column to a predetermined value. A control is configured to control the operation of the displacement motor and torque feedback motor and to inhibit and enable the steering function of the steering column.
