The invention discloses an automobile active steering coupling device based on a single-row planetary gear train and a steering system. The steering device comprises a mechanical transmission device and a power drive device. The power drive device comprises a displacement assistance motor, a worm wheel and a worm, wherein the worm wheel and the worm are meshed with each other. The mechanical transmission device is mainly composed of an input shaft, a sun wheel, a planet carrier, a planet gear, a gear ring, an output gear and an output shaft. The automobile steering system comprises a steering wheel, a torsion bar, a worm wheel and worm speed reduction mechanism, a cardan joint, a steering operation mechanism support, a gear and rack steering device and an active steering coupling device. The variable-transmission-ratio steering is achieved through the power coupling of the mechanism transmission device and the power drive device; the planet gear is of a double-gear structure, an elastic component and a thrust bearing are embedded between two gears, and the back clearance between the planet gear and the gear ring and the back clearance between the sun gear and the planet gear can be reduced; the overall structure is small in size, arrangement is convenient, the transmission efficiency is high, manufacturability is high, manufacturing expenses are low, gear shifting is stable, and the handling quality is good.
