The invention relates to the technical field of control of four-wheel drive pure electric vehicle power systems, and discloses a control method of a four-wheel drive pure electric vehicle power systemand a vehicle. A first motor, a second motor, a speed changer and a first two-way clutch are arranged on the vehicle, the first motor is in transmission connection with wheels of the vehicle throughthe first two-way clutch and the speed changer, the second motor is in transmission connection with the wheels of the vehicle, and the first motor and the second motor are both used for driving the vehicle to travel. The control method comprises driving travel control, and comprises the following steps of calculating travel torque required for vehicle travelling; judging whether the travel torqueis larger than the maximum torque which can be generated from the first motor to the wheel end or not; if yes, using the first motor and the second motor for driving the vehicle to travel at the sametime; and if not, using the first motor to drive the vehicle to travel, and enabling the second motor to be 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、一个变速器和第一双向离合器,所述第一电机通过所述第一双向离合器和所述变速器与车辆的车轮传动连接,所述第二电机与车辆的车轮传动连接,所述第一电机和所述第二电机均用于驱动车辆行驶,所述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;判定所述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,则所述第一电机和所述第二电机同时驱动车辆行驶;如果否,则所述第一电机驱动所述车辆行驶,所述第二电机处于静止状态。
