The invention discloses a four wheel independent steering electric car steering control method and a four wheel independent steering electric car steering control system, and solves the technical problem that a four wheel independent driving and four wheel independent steering electric car is lack of a stable and affordable steering strategy in the prior art. The four wheel independent steering electric car steering control method includes: when an electric car needs to swerve, obtaining a steering wheel turning angle and car speed of the electric car; based on a car speed and car speed transmission ratio mathematic model, obtaining a variable transmission ratio between the steering wheel angle and a rear wheel turning angle of the electric car at different car speeds; obtaining a front wheel turning angle of the electric car based on the steering wheel turning angle; obtaining a car ideal condition of the electric car based on a variable transmission ratio car ideal model, the car speed and the front wheel turning angle; simultaneously, obtaining a car virtual condition of the electric car based on a four wheel steering electric car linear two freedom model, the car speed and the front wheel turning angle; obtaining the rear wheel turning angle of the electric car based on the car ideal condition and the car virtual condition of the electric car, and controlling the electric car to swerve based on the front wheel turning angle and the rear wheel turning angle of the electric car.
