The invention belongs to the technical field of vehicle thermal management, and particularly relates to a vehicle thermal management system, a control method and a vehicle, and the extended-range vehicle thermal management system comprises an air conditioning system, a battery loop, a motor electric drive loop, a multi-way water valve and a front-end heat dissipation group; the air conditioning system comprises a heat exchanger, and the air conditioning system and the battery loop are connected through the heat exchanger; the automobile heat management system selectively conducts heat exchange on the air conditioning system and the battery loop according to the environment temperature, the battery cell temperature and/or the motor electric drive temperature, and selectively conducts heat exchange on the battery loop and the motor electric drive loop through the multi-way water valve. And the temperature of the electric drive cooling liquid in the motor electric drive loop is selectively reduced through the front end heat dissipation set. The problems that an automobile power system is slow in heat dissipation and low in strong cooling capacity are solved.
