The invention relates to a method for controlling an active rear axle steering device (16) of a motor vehicle (10) during steering from straight travel (20) in the case of a given actual dynamics of wheel guidance of the motor vehicle (10), in which an actual steering signal (25) of the motor vehicle (10) is received from at least one sensor by a control circuit (23), subsequently, a time-dependent curve of a differential signal (26) is calculated from the actual steering signal (25) by means of a wheel-guided dynamic model, said differential signal describing a deviation of the actual steering signal (25) from a virtual target steering signal, which is required, for example, in order to dynamically perform steering at a predetermined target, and the actual steering signal (25) is converted by means of a predetermined conversion rule. A target steering signal (27) for the rear axle steering device (16) is generated from the differential signal (26), and the rear axle steering device (16) is actuated with the target steering signal.
本发明涉及一种用于在机动车(10)的车轮引导的给定的实际动态的情况下,在从直线行驶(20)的转向期间控制机动车(10)的主动式后桥转向装置(16)的方法,其中,通过控制电路(23),从至少一个传感器接收机动车(10)的实际转向信号(25),随后借助车轮引导的动态模型从实际转向信号(25)计算差分信号(26)的随时间变化的曲线,差分信号描述了实际转向信号(25)与虚拟的额定转向信号的偏差,这例如是需要的,以便以预定的额定动态执行转向,并且通过预定的换算规则,由差分信号(26)产生用于后桥转向装置(16)的额定转向信号(27),并且以该额定转向信号驱控后桥转向装置(16)。
