A longitudinal dual-power-source vehicle drive assembly includes an automatic transmission (10), a first power source (71) and a second power source (72), wherein a transmission input shaft (21) and a transmission output shaft (32) of the automatic transmission (10) are coaxial, the transmission input shaft (21) is connected to an output shaft of the first power source (71), the transmission output shaft (32) is connected to an input shaft of the second power source (72), the output shaft of the second power source (72) is connected to the vehicle axle half shaft (50), and the automatic transmission (10) has transmissions of two speed ratios. The present disclosure realizes functions of direct driving and speed change by using dual electric motors and direct driving and deceleration by using dual electric motors, forms transmissions of multiple speed ratios, has flexible transmission modes, reduces the radial dimension of the drive assembly, and has no power interruption in gear shifting, which improves the riding comfort, the power performance, the acceleration performance and the gradeability of the vehicle.
