In some embodiments, the pressure sensor in the above scheme is selected as the pressure probe 7, and the temperature sensor is selected as the temperature probe 6. Therefore, the cost can be effectively reduced, the use is more convenient, and the narrow space of various working conditions can be met.

When the pressure difference between the pressure in the tire 2 and the ambient pressure is Δ p2 (Pa), it indicates that the tire pressure of the wheel is in a normal range, and if the cooling is continued, the tire pressure may exceed the normal range, which brings a safety hazard to driving. At this time, the electric energy storage device is controlled to stop providing electric energy for the semiconductor refrigeration sheet 1, so that the tire pressure of the wheel is within a normal range. The pressure difference delta p2 can be preset according to factors such as driving habits, weather environments and driving road conditions of users, automobile safety is improved, and automobile using experience of the users is improved.
