This invention relates to the field of industrial unmanned aerial vehicle (UAV) technology, specifically a hydrogen fuel cell and lithium battery hybrid UAV. The UAV includes a fuselage, a high-pressure hydrogen storage tank fixedly mounted on top of a gas cylinder mounting base, a battery stack mounted on the bottom of a mounting frame assembly, and a circuit control module located inside the mounting frame assembly. This hydrogen fuel cell and lithium battery hybrid UAV, based on multi-source data fusion and a sliding window anti-disturbance design, achieves accurate identification of all operating conditions, including steady-state cruise, high-power transients, surplus recharge, and regenerative braking. It is equipped with a differentiated intelligent power allocation algorithm, enabling a dynamic allocation strategy that allows for continuous and stable main power supply from the fuel cell during cruise, coordinated lithium battery replenishment during high-power conditions, and real-time recharge of the lithium battery with surplus power. Through a power change rate feedforward compensation design, it maximizes the utilization of the high energy density of hydrogen energy while simultaneously achieving energy recovery and reuse, further improving the system's energy utilization rate.

This invention provides a method for calculating the torque of a distributed loading vehicle and the distributed loading vehicle itself. The calculation method includes: obtaining the actual required torque based on the driving state, the battery's limited power, and the motor's rotational speed; distributing the actual required torque evenly to the front and rear axles, and further distributing the torque of the front axle to the two motors on the front axle and the torque of the rear axle to the two motors on the rear axle based on the steering angle, thus obtaining the required torque for all four motors; obtaining the axle slip ratio and axle acceleration, and if at least one of the following conditions is met: the slip ratio is greater than a preset slip ratio threshold, and the axle acceleration exceeds a preset acceleration threshold, then the required torque for the two motors corresponding to the abnormal axle is transferred, wherein the abnormal axle is the axle that meets the conditions. Therefore, it is possible to actively intervene in the torque of the abnormal axle after detecting slippage or lock-up, thereby improving vehicle safety, ensuring vehicle power performance, and reducing wheel wear.
