The invention relates to a hybrid electric vehicle and a control method thereof. A method of controlling a hybrid electric vehicle including an engine and a first electric machine connected to main driving wheels and a second electric machine connected to auxiliary driving wheels includes: determining a required torque; determining a first torque continuously output by the second motor based on the required torque and the vehicle speed in response to the fact that the preset condition is met; determining a second torque discontinuously output by the second motor based on a state of an engine clutch disposed between the engine and the first motor, a state of the transmission, or the required torque to compensate for the acceleration loss in a case where the acceleration loss occurs; a final torque of the second electric machine is determined based on the first torque and the second torque.

    本发明涉及一种混合动力电动车辆及其控制方法。混合动力电动车辆包括连接到主驱动轮的发动机和第一电机以及连接到辅助驱动轮的第二电机,控制混合动力电动车辆的方法包括:确定所需扭矩;响应于预定条件满足,基于所需扭矩和车速来确定第二电机连续输出的第一扭矩;基于布置在发动机和第一电机之间的发动机离合器的状态、变速器的状态或所需扭矩,确定第二电机不连续输出的第二扭矩,以在加速度损失发生的情况下补偿加速度损失;基于第一扭矩和第二扭矩来确定第二电机的最终扭矩。
