A vehicle temperature control system (01), comprising: a power supply device (100), a control device (200) and a temperature regulating device (300), The temperature regulating device (300) being made of a semiconductor material. A first end (001) of two ends of the temperature regulating device (300) is provided outside a vehicle, and a second end (002) thereof is provided inside the vehicle. The control device (200) is provided between the power supply device (100) and the temperature regulating device (300). The control device (200) is used to control the flow of the current, provided by the power supply device (100), on the two ends of the temperature regulating device (300), so as to make the first end (001) and the second end (002) of the temperature regulating device (300) absorb or release heat. The system solves the problem in the prior art that vehicle temperature control systems have a complex structure and high cost, and simplifies the structure of the vehicle temperature control system, reduces c
