In this work, a wireless remote-control function and fuzzy control function were added to the mini-loader of a hybrid gas-electricity powertrain. The loader uses a long-range (LoRa) protocol for communication, which is capable of long-distance signal transmissions and has a high level of sensitivity. A frequency-hopping mechanism based on received signal strength, center frequency, and sensitivity information was constructed for the LoRa system, which aids the transmission of information over long distances in a stable manner. This allows the loader to be utilized in remote regions or topographically complex areas. A fuzzy controller was incorporated to alleviate the fuel consumption problems of the hybrid powertrain and provided efficient and stable hybrid power by tuning the torque and rotation speed of the motor. The functionalized mini-loader has achieved data transfer success rates greater than 90% in wireless transmissions within a range of 100 m. The energy consumption of the functionalized powertrain was lowered by 8%.
