A method for identifying orientations of reconnected vehicles, specifically comprising the following steps: 101, installing an attitude sensor on the head of an engineering vehicle, the attitude sensor being installed on a driving box of a front driving cab, and the direction of the attitude sensor being consistent with the direction of the head of the vehicle; 102, comparing angle information of master and slave vehicles, and determining a coupling mode of the vehicles by means of an angle deference of the two vehicles to be reconnected; 103, manually selecting a work number of a salve vehicle to be reconnected for coupling, and confirming the coupling mode; and 104, after the coupling mode between the vehicles to be reconnected is clear, controlling a traveling direction and gear shifting of a reconnected vehicle set by means of operations on a master vehicle. The method for identifying a vehicle orientation by using an attitude sensor is simple and easy to implement, and the problem concerning confirmation of a coupling mode of engineering vehicles to be reconnected during wireless reconnection is solved, so that it is more convenient and quick to marshal maintenance trains each having one rail powered vehicle at either end and multiple unpowered vehicles at the middle.
