The invention relates to the technical field of control of four-wheel drive battery electric vehicle power systems, and discloses a control method of a four-wheel drive battery electric vehicle powersystem and a vehicle. A first motor, a second motor, a first two-way clutch and a second two-way clutch are arranged on the vehicle, the first motor is in transmission connection with the first two-way clutch, the second motor is in transmission connection with the second two-way clutch, and the control method comprises driving running control and comprises the following steps that the running torque required by running of the vehicle is calculated; whether the running torque is larger than the maximum torque which can be generated from the first motor to the wheel end or not is judged; if yes, the first two-way clutch and the two-way clutch are both in a combined state, so that the first motor and the second motor drive the vehicle to run at the same time; and if not, the first two-way clutch is in a combined state, and the second two-way clutch is in a separated state, so that the first motor drives the vehicle to run, and the second motor is in a static state.
本发明涉及四驱纯电动汽车动力系统的控制技术领域,公开了一种四驱纯电动汽车动力系统的控制方法及车辆。车辆上设置第一电机、第二电机、第一双向离合器和第二双向离合器,所述第一电机与所述第一双向离合器传动连接,所述第二电机与所述第二双向离合器传动连接,控制方法包括驱动行驶控制,其包括如下步骤:计算车辆行驶所需的行驶扭矩;判定行驶扭矩是否大于所述第一电机到轮端能够产生的最大扭矩;如果是,则第一双向离合器和所述双向离合器均处于结合状态,以使第一电机和所述第二电机同时驱动车辆行驶;如果否,则第一双向离合器处于结合状态,所述第二双向离合器处于分离状态,以使第一电机驱动所述车辆行驶,所述第二电机处于静止状态。
