This invention belongs to the field of motor drive technology, and more specifically relates to a coaxial planetary gear set two-speed dual-motor independent drive architecture and control strategy. The drive architecture includes coaxial drive motors TM1 and TM2, a double-cascaded planetary gear set, and wet friction brake pad mechanisms B1 and B2. Drive motor TM1 drives the wheels through the two-speed planetary gear set mechanism, while drive motor TM2 directly drives the wheels. This achieves high torque and ultra-high vehicle speed with a small size and lightweight design, greatly increasing the overall vehicle energy efficiency. Furthermore, depending on the vehicle's operating speed, when high torque is required at low, medium, and high speeds, drive motors TM1 and TM2 can drive the wheels simultaneously to achieve rapid acceleration. At ultra-high speeds, drive motor TM2 alone drives the wheels.
