The invention belongs to the field of electric vehicles, and discloses a vehicle thermal management system and a thermal management control method. The vehicle thermal management system comprises a drive cooling system, a battery thermal management system and a first switching device. An electric drive cooling loop is formed in the drive cooling system, and an electric drive water pump is arranged on the electric drive cooling loop; a battery cooling loop is formed in the battery thermal management system, and a battery water pump is arranged on the battery cooling loop; the first switching device is used for communicating the electric drive cooling loop and the battery cooling loop. According to the vehicle heat management system, when any one of the electric drive water pump and the battery water pump breaks down, the electric drive cooling loop and the battery cooling loop are communicated through the first switching device, liquid in the two loops is driven to flow through one water pump, refrigeration or heating is conducted synchronously, and the cooling efficiency is improved. And normal operation of the whole vehicle thermal system is ensured.
