The invention discloses an automatic temperature control method and device for a thermal vacuum experiment of a spacecraft. The method comprises the steps that an initial temperature control area is divided based on the maximum temperature difference value of the initial temperature control area of the spacecraft, and a plurality of temperature control sub-areas are obtained; determining a first target temperature and a second target temperature of each temperature control sub-region; the first target temperature is the target temperature of the spacecraft in the heating stage and the high-temperature stage, and the second target temperature is the target temperature of the spacecraft in the cooling stage and the low-temperature stage; and for each temperature control sub-region, obtaining a performance parameter of the spacecraft in a high-temperature environment based on the first target temperature and a performance parameter of the spacecraft in a low-temperature environment based on the second target temperature, and determining the performance of the spacecraft according to the obtained performance parameters. By adopting the method, the temperature control precision in each temperature control area in the thermal vacuum test process can be improved.
