[0051] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0052] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] Example 1

[0054] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a vehicle fan configuration method provided in this embodiment. The vehicle fan configuration method includes:

[0055] S101. When the vehicle controller of the target vehicle is woken up, read the fan configuration type identifier.

[0056] S102. When the fan configuration type is identified as the first preset value, the current fan type of the target vehicle is identified through the first pin, the second pin and the third pin of the vehicle controller; wherein, the fan type is a PWM fan or a two-speed fan.

[0057] In this embodiment, the first preset value can be 0 or 3, indicating that the fan has not been identified or the fan type identification has failed, and the fan needs to be re-identified.

[0058] S103. Set the fan configuration type identifier to the second preset value according to the fan type, and store the fan type.

[0059] In this embodiment, the second preset value can be 1 or 2, which indicates that the fan has been successfully identified and does not need to be identified again.

[0060] In this embodiment, the fan type is a PWM fan or a two-speed fan.

[0061] S104. Configure the target vehicle with the appropriate fan according to the fan type.

[0062] As an optional implementation, the method further includes:

[0063] When the fan configuration type is identified as the second preset value, the stored fan type is retrieved, and the corresponding fan configuration is performed on the target vehicle according to the fan type.

[0064] In this embodiment, this application provides a method for identifying the type of assembled fan based on VCU pin fault detection. The fan configuration identification scenarios mainly fall into the following two categories:

[0065] (1) After all components are installed in the factory and the battery is connected, the VCU will identify the fan configuration when it is woken up for the first time.

[0066] (2) After the fan is replaced and the VCU software is flashed, the VCU is woken up for the first time to recognize the fan configuration.

[0067] Implementing this method allows for disabling the driving of Pin1, Pin2, and Pin3 in both scenarios, immediately after the VCU is first woken up, while simultaneously detecting faults in Pin1, Pin2, and Pin3. After 200ms (calibrated value), the driving of Pin1, Pin2, and Pin3 is enabled, again with continued fault detection. Specifically, if Pin1 is detected as a closed circuit and Pin2 and Pin3 as open circuits without faults when the driving is disabled, and Pin1, Pin2, and Pin3 are all detected as normal after enabling, then the vehicle model can be identified as having a PWM wave controlled fan configuration. Conversely, if Pin1 is detected as an open circuit and Pin2 and Pin3 as closed circuits without faults when the driving is disabled, and Pin1, Pin2, and Pin3 are detected as normal after enabling, then the vehicle model can be identified as having a two-speed fan configuration. In this case, the identified fan type needs to be stored at the lower level for direct recognition and use upon the next VCU wake-up.

[0068] In this embodiment, the subject executing the method can be a computing device such as a computer or server, and no limitation is made in this embodiment.

[0069] In this embodiment, the subject executing the method can also be a smart device such as a smartphone or tablet, and no limitation is made in this embodiment.

[0070] As can be seen, the vehicle fan configuration method described in this embodiment can automatically identify the type of fan configured on the vehicle without human intervention, saving manpower and resources, avoiding errors caused by manual configuration, and thus improving configuration efficiency.

[0071] Example 2

[0072] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a vehicle fan configuration method provided in this embodiment. The vehicle fan configuration method includes:

[0073] S201. When the vehicle controller of the target vehicle is woken up, read the fan configuration type identifier.

[0074] S202. When the fan configuration type is identified as the first preset value, without enabling the first pin, the second pin, and the third pin of the vehicle controller, fault detection is performed on the first pin, the second pin, and the third pin simultaneously to obtain the first fault detection result.

[0075] In this embodiment, the first preset value can be 0 or 3, indicating that the fan has not been identified or the fan type identification has failed, and the fan needs to be re-identified.

[0076] S203. After a preset time period, when the first, second, and third pins are enabled, fault detection is performed on the first, second, and third pins simultaneously to obtain a second fault detection result.

[0077] In this embodiment, the preset time period can specifically be 200ms.

[0078] S204. Determine whether the first fault detection result is the preset first detection result. If yes, proceed to step S205; otherwise, proceed to step S207.

[0079] In this embodiment, the first detection result is preset to include the first pin being a closed circuit, and the second and third pins being open circuits and without faults.

[0080] S205. Determine whether the second fault detection result is the preset second detection result. If yes, proceed to step S206; otherwise, proceed to step S209.

[0081] In this embodiment, the preset second detection result includes that the first pin, the second pin, and the third pin are all normal.

[0082] S206. Determine that the target vehicle is currently configured with a PWM fan and proceed to step S210.

[0083] S207. Determine whether the second fault detection result is the preset second detection result. If yes, proceed to step S208; otherwise, proceed to step S209.

[0084] S208. Determine that the target vehicle is currently equipped with a two-speed fan and proceed to step S210.

[0085] S209. Output fault information indicating a fault in the vehicle controller, store the fault code indicating a fault in the vehicle controller, and end this process.

[0086] S210. Set the fan configuration type identifier to the second preset value according to the fan type, and store the fan type.

[0087] In this embodiment, the second preset value can be 1 or 2, which indicates that the fan has been successfully identified and does not need to be identified again.

[0088] S211. Configure the target vehicle with the appropriate fan according to the fan type.

[0089] As an optional implementation, the method further includes:

[0090] When the fan configuration type is identified as the second preset value, the stored fan type is retrieved, and the corresponding fan configuration is performed on the target vehicle according to the fan type.

[0091] Please refer to Figure 5 , Figure 5 A schematic diagram of the circuit structure used in a vehicle fan configuration method is shown. Upon initial wake-up, the VCU identifies whether the vehicle is configured with a PWM fan or a two-speed fan via three pins: Pin1, Pin2, and Pin3.

[0092] For details, please refer to Figure 6 , Figure 6 The diagram illustrates an example flowchart of a vehicle fan configuration method. As can be seen, after the VCU is powered on and woken up, it first reads the fan configuration type. If the fan configuration type is 0 or 3, it indicates that the fan has not been identified or the fan type identification has failed. In this case, the fan needs to be re-identified. If the fan type is 1 or 2, it indicates that the fan has already been successfully identified and does not need to be identified again.

[0093] This implementation allows for disabling the driving of Pins 1, 2, and 3 upon the VCU's initial wake-up, while simultaneously detecting faults in Pins 1, 2, and 3. After 200ms (calibrated value), the driving of Pins 1, 2, and 3 is enabled, again with continued fault detection. Specifically, if Pin 1 is detected as a closed circuit and Pins 2 and 3 as open circuits without faults when the driving is disabled, and Pins 1, 2, and 3 are all detected as normal after enabling, then the vehicle model can be identified as having a PWM-controlled fan configuration. Conversely, if Pin 1 is detected as an open circuit and Pins 2 and 3 as closed circuits without faults when the driving is disabled, and Pins 1, 2, and 3 are detected as normal after enabling, then the vehicle model can be identified as having a two-speed fan configuration. The identified fan type needs to be stored at the lower level for direct recognition and use upon the next VCU wake-up.

[0094] In this embodiment, the subject executing the method can be a computing device such as a computer or server, and no limitation is made in this embodiment.

[0095] In this embodiment, the subject executing the method can also be a smart device such as a smartphone or tablet, and no limitation is made in this embodiment.

[0096] As can be seen, the vehicle fan configuration method described in this embodiment can automatically identify the type of fan configured on the vehicle without human intervention, saving manpower and resources, avoiding errors caused by manual configuration, and thus improving configuration efficiency.
