The invention discloses a dual-motor dual-mode electric driving wheel transmission device and a vehicle with the same, and belongs to the technical field of electric driving wheels. A second planet carrier in a second planet row is connected with a second planet wheel in the second planet row and a first gear ring in a first planet row; the first driving motor is connected with a second planet carrier in the second planet row through a first input component; the second driving motor simultaneously drives the first sun gear and the second sun gear to rotate; an inner ring of the one-way clutch is connected with a first planet carrier in the first planet row, and an outer ring is connected with the machine shell and used for enabling the first planet carrier to rotate unidirectionally. The output component is connected with a second gear ring in the second planet row; the running and parking integrated brake is connected with the output component and used for braking the output component. The dual-motor dual-mode electric driving wheel transmission device does not need a complex hydraulic or electric actuating mechanism for gear shifting, is simple in structure and easy to engineer, realizes mode switching by controlling the motor and the one-way clutch, and improves the stability and reliability of gear shifting.
