The invention provides a torque distribution method, device and equipment for a hybrid heavy truck. The invention provides a torque distribution method of a hybrid heavy truck. The hybrid heavy truck is formed by matching a fuel trailer with an electrically-driven trailer. The method comprises the steps that according to the pedal position at the current moment and the vehicle speed at the current moment, the static torque requirement is obtained; according to the pedal position at the current moment, the pedal position at the previous moment, the time difference between the current moment and the previous moment and the dynamic response coefficient of the fuel trailer, the dynamic torque requirement is obtained; determining an overall torque demand according to the static torque demand and the dynamic torque demand; searching a target distribution proportion matched with the vehicle speed and the overall torque demand at the current moment from a pre-established torque distribution table; and torque distribution is conducted on the fuel trailer and the electric drive trailer according to the target distribution proportion. According to the torque distribution method, device and equipment for the hybrid heavy truck, the dynamic property, economical efficiency and safety of the hybrid heavy truck can be improved.
