It is therefore a necessary trend to apply autopilot technology to shunting operations. The shunting operation is carried out in the field section, and the shunting mode does not depend on the track circuit code sending and the line data of the transponder, so that the ground driving permission cannot be received when the automatic driving technology is adopted, and therefore, how to calculate the movement authorization for the shunting mode becomes a key technology of the automatic driving application.
According to the invention, the shunting operation plan is received through the vehicle-mounted equipment, meanwhile, the shunting access information automatically triggered according to the shunting operation plan and the line data sent by the trackside transponder are calculated by the vehicle-mounted equipment in a shunting mode, the shunting control curve is calculated according to the driving license, and the control safety of automatic shunting is ensured.
