The invention relates to a steer-by-wire steering system (6) for a motor vehicle (1). The steer-by-wire steering system (6) has at least one sensor unit (7) for detecting a current steering position of a manually drivable steering unit (2) of the motor vehicle (1), at least one electronic unit (8) connected to the sensor unit (7) and configured to generate a steering command in a manner dependent on the respective current steering position of the steering unit (2). In order to achieve pull drift compensation in the steer-by-wire steering system (6), the electronic unit (8) is configured to determine whether the motor vehicle (1) is in a straight driving state during a driving operation based on current vehicle dynamics data detected by the sensor, determine whether the current steering position of the steering unit (2) deviates from the straight travel position for a time period of a specified length and/or for a distance of a specified length during the straight travel state of the motor vehicle (1), if the current steering position of the steering unit (2) deviates from the straight travel position for a time period of a specified length and/or for a distance of a specified length during the straight travel state of the motor vehicle (1), a compensation steering command is generated by taking into account the deviation of the current steering position of the steering unit (2) from the straight travel position, and the compensated steering command is combined with the steering command to form a corrected steering command.

    本发明涉及用于机动车辆(1)的线控转向转向系统(6),该线控转向转向系统(6)具有至少一个用于检测机动车辆(1)的可手动驱动的转向单元(2)的当前转向位置的传感器单元(7)、至少一个连接至传感器单元(7)并且配置成以依赖于转向单元(2)的相应当前转向位置的方式生成转向指令的电子单元(8)。为了在线控转向转向系统(6)中实现拉动漂移补偿,电子单元(8)配置成根据传感器检测到的当前车辆动态数据来确定机动车辆(1)在驾驶操作过程中是否处于直行行驶状态下,确定在机动车辆(1)处于直行行驶状态过程中转向单元(2)的当前转向位置在指定长度的时间段内和/或在指定长度的距离内是否偏离直行行驶位置,并且如果在机动车辆(1)处于直行行驶状态过程中转向单元(2)的当前转向位置在指定长度的时间段内和/或在指定长度的距离内偏离直行行驶位置,则将转向单元(2)的当前转向位置与直行行驶位置的偏差纳入考虑而生成补偿转向指令,并且将补偿转向指令与转向指令相结合以形成校正转向指令。
