The invention provides a torque distribution method, device and equipment for a pure electric heavy truck. According to the torque distribution method, device and equipment for the pure electric heavy truck provided by the invention, the torque demand is searched from the MAP table corresponding to the current driving mode, the initial distribution proportion is determined from the torque distribution table, and when the first residual electric quantity of the electric trailer is greater than the preset threshold value, the initial distribution proportion is determined. And correcting the initial distribution proportion according to the first residual electric quantity and the second residual electric quantity of the electric trailer, and limiting the corrected distribution proportion obtained by correction to obtain a final target distribution proportion. On one hand, different driving modes use different MAP tables to determine torque requirements, so that the driving experience and the vehicle performance can be improved, and on the other hand, the initial distribution proportion is determined based on the pre-established torque distribution table, so that the energy efficiency can be improved, and the waste can be reduced; in addition, the distribution proportion is corrected and limited according to the remaining electric quantity, the charge state can be balanced, energy consumption minimization and endurance maximization are achieved, and driving safety and performance stability are guaranteed.

    本申请提供一种纯电重卡的扭矩分配方法、装置和设备。本申请提供的纯电重卡的扭矩分配方法、装置和设备,从当前驾驶模式对应的MAP表中查找扭矩需求,再从扭矩分配表中确定初始分配比例,进而在电动拖车的第一剩余电量大于预设阈值时,根据第一剩余电量与电动挂车的第二剩余电量修正初始分配比例,并对修正得到的修正分配比例进行限制,得到最终的目标分配比例。一方面,不同驾驶模式用不同的MAP表确定扭矩需求,可提高驾驶体验和车辆性能,另一方面,基于预先建立的扭矩分配表来确定初始分配比例,可以提高能效、减少浪费;此外,根据剩余电量修正并限制分配比例,可均衡荷电状态、实现能耗最小化和续航最大化,保证行驶安全和性能稳定。
