1. A steering system for a motor vehicle comprising:
an electronics control unit configured to:
determine a present steering position of a manually actuatable steer-by-wire steering unit of the motor vehicle based on sensor data;
generate a steering command based on the present steering position of the steer-by-wire steering unit;
then, determine, based on sensor-detected present vehicle dynamics data, whether the motor vehicle is in a straight-ahead running situation during driving operation;
upon determining the motor vehicle is in the straight-ahead running situation, determine whether the present steering position of the steer-by-wire steering unit deviates from a straight-ahead running position of the steer-by-wire steering unit for at least one of a specified time period and a specified traveling distance of the motor vehicle;
upon determining a deviation of the present steering position of the steer-by-wire steering unit from the straight-ahead running position, generate a compensation steering command based on the deviation; and
generate a corrected steering command by combining the compensation steering command with the steering command,
wherein a resetting unit, that includes a resetting spring or a servo motor, is configured to, upon determining the present steering position deviates from the straight-ahead running position, act on the steer-by-wire steering unit with a resetting force in a direction of the straight-ahead running position.
