The invention relates to a method for saving power in a steering system (1) of a motor vehicle, comprising a wheel actuator (5) acting on a rack (6) for turning steerable wheels (4), and a control unit (10) for calculating an operating signal for the wheel actuator (5), the control unit (10) comprises a position controller which calculates a motor torque request as a function of the actual position or/and the measured position of the rack (6) and the requested rack position, whereby the method comprises the following steps: if the motor vehicle is stopped and no steering input is provided, starting the motor torque request; detecting, by a passive mode detection unit that is part of the control unit (10), a passive mode of the steering system (1); and setting the motor torque request to zero to save power in a case where the passive mode detection unit detects the passive mode.

    本发明涉及一种在机动车辆的转向系统(1)中节省功率的方法,所述转向系统包括作用于齿条(6)的车轮致动器(5)以及控制单元(10),所述车轮致动器(5)用于转动可转向车轮(4),所述控制单元(10)计算用于所述车轮致动器(5)的操作信号,其中,所述控制单元(10)包括位置控制器,所述位置控制器根据所述齿条(6)的实际位置或/和测量位置,以及所请求的齿条位置,计算电机转矩请求,其中,所述方法包括以下步骤:如果机动车辆停止并且未提供转向输入,由作为所述控制单元(10)的一部分的被动模式检测单元检测所述转向系统(1)的被动模式;以及在被动模式检测单元检测到被动模式的情况下,将电机转矩请求设置为零,以节省功率。
