The invention discloses a real-time energy management method based on dual-motor driving, a motor controller and a vehicle, and relates to the field of motor control. The method comprises the following steps: acquiring a wheel side required torque and a real-time vehicle speed of a vehicle; calculating motor peak torque under different motor working modes according to the real-time vehicle speed; determining an optimal motor working mode and a corresponding expected energy consumption power and expected power distribution proportion according to the wheel side demand torque and the motor peak torque; acquiring historical energy consumption power in a motor working mode at a historical moment, and determining a final power distribution proportion in combination with a preset reward and punishment factor and expected energy consumption power; and according to the final power distribution proportion, distributing the wheel side demand torque to the first motor and the second motor. Compared with the prior art, errors caused by a table look-up mode can be greatly reduced, and the driving comfort is improved while the economical efficiency is guaranteed by introducing reward and punishment factors.

    本发明公开了一种基于双电机驱动的实时能量管理方法、电机控制器及车辆,涉及电机控制领域。所述方法包括:获取车辆的轮边需求扭矩和实时车速;根据实时车速计算不同电机工作模式下的电机峰值扭矩;根据轮边需求扭矩和电机峰值扭矩,确定最优电机工作模式,以及对应的预期能耗功率与预期功率分配比例;获取历史时刻的电机工作模式下的历史能耗功率,结合预设的奖惩因子与预期能耗功率,确定最终功率分配比例;根据最终功率分配比例,将轮边需求扭矩分配给第一电机和第二电机。相较于现有技术,可大幅度降低由于查表方式带来的误差,通过引入奖惩因子,在保证经济性的同时提高了驾驶舒适性。
