The invention relates to a front wheel and rear wheel drive steering control system of an automobile in the technical field of automobile engineering. Steering wheel steering angle sensors are respectively connected with a drive turning electronic control unit; one end of each steering wheel steering angle sensor is connected with a steering wheel, and the other end of each steering wheel steering angle sensor is connected with a front wheel steering motor servo control unit; the front wheel steering motor servo control unit is respectively connected with a front wheel steering angle displacement sensor and a front wheel steering execution mechanism; a rear wheel steering motor servo control unit is respectively connected with a rear wheel steering angle displacement sensor and a rear wheel steering execution mechanism; the front wheel steering execution mechanism is connected with a front wheel, and the rear wheel steering execution mechanism is connected with a rear wheel. The invention combines front wheel drive steering and rear wheel drive steering, improves the lateral dynamic performance of the automobile, the driving characteristics of a driver and the operating stability of the automobile, changes a steering angle of the front wheel and the rear wheel in real time according to the drive working condition and a running parameter of the automobile and ensures that the automobile response follows the output response of a reference automobile model.
