The invention discloses an automobile active steering coupling device based on double rows of planetary gear trains and a steering system. The automobile active steering coupling device comprises a mechanical transmission device and a power drive device. The mechanical transmission device comprises the planetary gear train I and the planetary gear train II, wherein the planetary gear train I and the planetary gear train II are arranged in parallel and share one gear ring, a manual input portion is input to the planetary gear train I through a sun gear I, a displacement assisting motor input portion is delivered to a planet carrier I through a worm wheel and a worm and is input to the planetary gear train I, and the planet carrier I and the sun gear I conduct input at the same time, and output is conducted through the gear ring. A planet carrier II is fixedly arranged, the gear ring inputs movement into the planetary gear train II, and finally outward output is conducted through a sun gear II. The automobile active steering coupling device is small in overall structure, the installation space is saved, and arrangement is convenient; the variable-transmission-ratio steering is achieved, the steering stability is high, the failure rate is low, reliability is high, and the control process is more flexible.
