The invention discloses an automobile active steering coupling device capable of achieving the variable transmission ratio 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 a planetary gear train I and a planetary gear train II, wherein the planetary gear train I and the planetary gear train II are arranged in parallel, a gear ring I in the planetary gear train I and a planet carrier II in the planetary gear train II are connected together, 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 I. The planet carrier II is fixedly arranged, the planet carrier II 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 number of gear shifting changes is large, the transmission efficiency is high, the steering stability is high, the failure rate is low, reliability is high, and the control process is more flexible.
