Beschreibung
Zusammenfassung:	The invention discloses a control method and system for electric automobile dual motor driving. An electric automobile comprises a first power motor, a second power motor, a driving wheel and a transmission device for transmitting power between the motor and the driving wheel. The transmission device limits a first gear with a first transmission ratio and a second gear with a second transmission ratio. Furthermore, the transmission device can shift between the first power motor at the second gear and a single motor driving position which is connected with the transmission device in operation, between the first power motor at the second gear, the second power motor at the first gear and a dual motor first gear driving position which is connected with the transmission device in operation at the same time, and between the first power motor at the second gear, the second power motor at the second gear and a dual motor second gear driving position which is connected with the transmission device in operation at the
