Abstract

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.
