The invention relates to an unmanned racing car straight gear rack type man-machine co-driving dual-mode steering system which comprises a control mechanism, a steering gear and a transmission mechanism, the control mechanism comprises a steering wheel, a steering column transmission mechanism and a lower steering column gear, and the steering gear comprises a reversing gear box, a rack and a displacement sensor. The transmission mechanism comprises a motor, a speed reducer and an electromagnetic clutch; the steering wheel is in transmission connection with the lower steering column gear through the steering column transmission mechanism, and the lower steering column gear is connected with the reversing gear box in a matched mode and penetrates through the reversing gear box to be connected with the rack in a matched mode. The output end of the motor is connected with the speed reducer which is connected with the reversing gear box in a matched mode through the electromagnetic clutch. And the displacement sensor is linked with the rack so as to detect the displacement of the rack in real time. The system can flexibly achieve switching between manual operation and unmanned operation, steering is flexible and smooth, and the response speed is high.
