A dual-mode active rear-wheel steering device based on a multi-linkage mechanism, including: a steering angle control motor with a speed-reduction mechanism, a multi-linkage mechanism assembly for converting rotational motion of the steering angle control motor into linear motion of an end of the push rod, a steering actuating mechanism for converting linear motion of the multi-linkage mechanism assembly into rotation of a knuckle around a kingpin to make the rear wheels steer, a first electromagnetic pin puller and a second electromagnetic pin puller respectively configured to control a first extendable-retractable push rod assembly and a second extendable-retractable push rod assembly to work at a fixed or variable axial length. The device uses the steering angle control motor to drive the two rear wheels to turn in the same direction or opposite directions through the control of energized state of the two electromagnetic pin pullers.
