The invention discloses a novel motor-based electric car four-wheel independent steering system, and aims at improving maneuverability and handling stability of an electric car. The four-wheel independent steering system has the advantages that when an electric car turns at low speed, front and rear wheels perform antiphase steering, a turning radius of the car can be reduced, and the mobility of the electric car is improved; when the electric car turns at high speed, the front and rear wheels mainly perform in-phase steering, a side slip angle of the car can be reduced, the steady-state overshoot amount of a yaw rate of the car and the like are lowered, and vehicle handling stability is further improved. The steering system comprises novel motors, a connecting mechanism and a transmission mechanism, wherein each novel motor adopts a linear transmission motor; the connecting mechanism is used for connecting the linear transmission motors with the transmission mechanism, and comprises a cylindrical connecting sleeve; the transmission mechanism comprises a steering knuckle arm. Four wheels are all steering wheels and respectively correspond to one linear transmission motor; the four linear transmission motors are mutually independent and directly drive the steering of the respectively corresponding wheel.
