A thermal management system control method for a vehicle is disclosed. An embodiment of the present disclosure provides a thermal management system control method for a vehicle, including: (A) a process in which a controller determines whether a track driving mode is selected based on data detected from a data detector before track driving of the vehicle, and determines an alignment position of a valve; (B) a process in which the controller, through the process (A), determines the alignment position of the valve to control a water pump or an oil pump, and operates an air conditioner; and (C) a process in which, when the air conditioner is operated through the process (B), the controller controls a battery chiller expansion valve and a compressor, and ends the control.

In the present disclosure, heat sources for cooling and heating conditioning air are integrated as a coolant, both cooling performance and heating performance are ensured only by the coolant, and an entire package is reduced. That is, since a first air conditioning heat exchanger and a second air conditioning heat exchanger adjust a temperature of air, various types of air conditioning modes including cooling and heating modes may be implemented without using a separate temperature adjusting door. Accordingly, an overall size of an air conditioner is reduced. In addition, during cooling and heating processes, the first air conditioning heat exchanger and the second air conditioning heat exchanger are integrated and utilized. Therefore, the size of the heat exchanger may be reduced, the interior space may be ensured, and the air conditioning performance may be ensured without increasing a size of the heat exchanger.
