[0106] Refer figure 2 with 3 When the engine assembly 6 is started by a low temperature mode or a normal temperature mode, it is also included to charge the low temperature start battery assembly 4, wherein when the low temperature start battery assembly 4 voltage is less than the first preset voltage, when the car is stopped again The low temperature start battery assembly 4 may not be possible to perform starting, and therefore, when the vehicle starts and the low temperature start battery assembly 4 voltage is less than the first preset voltage, the sixth control switch 42b is closed, and the low temperature start battery assembly 4 is charged. After reaching the preset, it is time to stop charging, to ensure that the low temperature start battery assembly 4 can start to start the engine assembly 6 smoothly.

[0107] Another embodiment of the present invention proposes a computer readable storage medium that stores a computer program, and when the computer program is executed by the processor, the vehicle start operation control method as described above is realized.

[0108] The computer readable storage medium of the present invention is similar to the beneficial effect of the car start operation control method relative to the prior art, and will not be described later.

[0109] While the present invention disclosures, the present invention is not limited thereto. Those skilled in the art can make various fracture and modifications without departing from the spirit and scope of the invention, and therefore the scope of the invention should be based on the scope of the claims.
