The invention discloses a control method and device of a dual-motor hybrid power vehicle and the vehicle. The method comprises the following steps: calculating a torque drop rate of a series drive motor; calculating the torque drop time of the series drive motor; comparison value information is obtained, the comparison value information at least comprises a first comparison value and a second comparison value, the first comparison value is a preset comparison value of the torque drop rate of the series drive motor, and the second comparison value is a preset comparison value of the torque drop time of the series drive motor; and generating a target control strategy set based on the torque drop rate of the series drive motor, the torque drop time of the series drive motor and the comparison value information, wherein the target control strategy set is used for controlling the drive motor to control the torque drop at different torque drop slopes. The technical problem that due to the fact that engine torque response is slow, the power battery is prone to being overcharged and overdischarged is solved.

    本发明公开了一种双电机混合动力车辆的控制方法、控制装置及车辆。其中,该方法包括:计算串联驱动电机扭矩下降速率;计算串联驱动电机扭矩下降时间;获取比较值信息,比较值信息至少包括第一比较值、第二比较值,第一比较值为串联驱动电机扭矩下降速率的预设的比较值,第二比较值为串联驱动电机扭矩下降时间的预设的比较值;基于串联驱动电机扭矩下降速率、串联驱动电机扭矩下降时间和比较值信息生成目标控制策略集,目标控制策略集用于控制驱动电机以不同的扭矩下降斜率控制其扭矩下降。本发明解决了由于发动机扭矩响应较慢导致的动力电池易产生过充过放现象的技术问题。
