The invention relates to a thermal management system control method and device, a vehicle, a storage medium and a system, and relates to the technical field of power system management of hybrid power vehicles. The method comprises the steps of obtaining the rotating speed and torque of a motor; according to a preset heat production rate MAP and the rotating speed and the torque of the motor, the operation working condition of the motor is determined; the heat production rate MAP is used for representing the motor heat production rate distribution condition of the motor at different rotating speeds and torques; determining a target cooling flow supply table corresponding to the motor according to a corresponding relation between a preset operation condition and a cooling flow supply table and the operation condition of the motor; and cooling oil is supplied to a cooling loop of the motor according to the target cooling flow supply table. The method is suitable for the running process of the vehicle, and the running condition of the motor can be accurately judged, so that the cooling flow supplied by the cooling pump for controlling the cooling flow is matched with the actual demand of the motor.
