This invention provides a heavy-duty truck modular hybrid trailer drive system and method based on real-time traction force, relating to the field of vehicle energy management technology. The system includes a heavy-duty truck tractor unit, a modular secondary trailer, and a general cargo trailer. The modular secondary trailer is detachably connected to the heavy-duty truck tractor unit via a standard saddle, adapting to existing heavy-duty trucks without modification. The heavy-duty truck tractor unit can be driven by a direct-drive engine, pure electric, or range-extended hybrid system. The modular secondary trailer is equipped with a modular energy source module, a drive motor, and an RCU controller. The modules are quick to install and remove and offer multiple options. The VCU and RCU work together to achieve optimal torque distribution, triple validity checks, and real-time fine-tuning, recovering kinetic and gravitational potential energy during braking. This invention achieves coordinated drive between the tractor unit and trailer, reducing energy consumption, increasing range, allowing the trailer to operate independently, adapting to multiple operating conditions, and significantly improving safety and operational efficiency.
