Beschreibung
Zusammenfassung:	The invention discloses a vehicle, an electric drive axle and a control method thereof. The electric drive axle is mounted on a vehicle chassis and includes a central drive mechanism. The drive mechanism includes two motors arranged coaxially, wherein the motor shafts of the two motors are both connected with reduction mechanisms and can be in driving connection to wheels on both sides through thereduction mechanisms. The electric drive axle also comprises a control unit in signal connection to both of the motors to switch the working modes of the two motors according to the driving conditionof the vehicle. Components such as an gearbox, a differential and the like in a traditional electric drive axle are removed from the electric drive axle provided by the invention, so as to greatly simplify the structure of the electric drive axle, save a space under the chassis, contribute to the optimization of the overall vehicle frame arrangement and reduce the weight of the electric drive axle for reducing the running
