The invention discloses a pure electric vehicle torque management control method, which has the main design conception that after a torque management function is in an on state, a torque arbitration function and a torque distribution function are started, and the torque arbitration demand torque comprises a driving demand torque, an intelligent demand torque and an energy recovery demand torque; determining a vehicle function corresponding to the current required torque type based on the arbitration result; and setting or dynamically adjusting the driving torque distribution ratio of the front axle and the rear axle or the recovery torque distribution ratio of the front axle and the rear axle according to the required torque type determined after arbitration in combination with the currently selected road mode and/or driving mode of the vehicle. Reasonable decision making is carried out on the torque demand of the pure electric vehicle, more comprehensive and refined front and rear axle torque matching is carried out by utilizing the decision making result and combining driving and road modes, and an effective solution thought is provided for the field of pure electric vehicles.

    本发明公开了一种纯电动车辆扭矩管理控制方法,本发明的主要设计构思在于,在扭矩管理功能处于开启状态后,开启扭矩仲裁功能以及扭矩分配功能:其中,扭矩仲裁的需求扭矩包括:驱动需求扭矩、智能化需求扭矩、能量回收需求扭矩;基于仲裁结果,确定当前的需求扭矩类型所对应的车辆功能;根据仲裁后所确定的需求扭矩类型,结合车辆当前所选的道路模式和/或驾驶模式,对前轴与后轴的驱动扭矩分配比或者前轴与后轴的回收扭矩分配比,进行设置或动态调整。本发明对于纯电动车辆的扭矩需求进行合理决策,并利用决策结果并结合驾驶与道路模式,进行更为全面、细化的前后轴扭矩配比,为纯电动车辆领域提供了行之有效的解决思路。
