[0039] See also Figure 1 , Figure 1A flow chart of a vehicle software configuration method provided by an embodiment of the present invention is shown. The vehicle software configuration method can be applied to an electronic controller, in which different versions of software are stored with different configurations. The different configurations are other configurations in the configuration information of each version of software except for the same configuration. The specific flow of this embodiment is described below using an electronic controller as an example. Figure 1 The process shown is described in detail, and the vehicle software configuration method may specifically include the following steps:

[0040] Step 110: Obtain the software version to be switched to in the vehicle.

[0041] In some embodiments, the electronic controller is disposed inside the vehicle, and the vehicle is provided with a vehicle display screen, which is communicatively connected to the electronic controller. The user can input the vehicle model in the vehicle display screen, and the electronic controller can obtain the software version to be switched to the vehicle according to the model.

[0042] The user can input the vehicle model by typing. The user can also input the vehicle signal by voice input.

[0043] Step 120: Determine the corresponding target difference configuration according to the software version to be switched.

[0044] In some embodiments, such as Figure 2 As shown, different versions of software stored in the electronic device have their own differential configurations. The current software version has the same configuration in the configuration information of each version of the software. The electronic controller stores the correspondence between the software version, the differential configuration and the switch quantity. The electronic controller can determine the switch quantity of each switch according to the software version to be switched and the correspondence, and determine the differential configuration with the switch quantity being on as the target differential configuration.

[0045] For example, the corresponding relationship between the software version, the difference configuration and the switch quantity quality is shown in Table 1. If the software version is EVR.V1.0, it is determined that the switch quantities of switch 1 and switch 2 are both on, and the difference configuration 1 and the difference configuration 2 are determined as the target configuration. Among them, EVR stands for Extended-Range Electric Vehicle (EVR), and EV stands for Electric Vehicle (EV).

[0046] Table 1

[0047]

[0048] Step 130: Switch the difference configuration corresponding to the current software version to the target difference configuration.

[0049] The vehicle software configuration method provided by the embodiment of the present invention obtains the software version to be switched by the vehicle, determines the corresponding target difference configuration according to the software version to be switched, and switches the difference configuration corresponding to the current software version to the target difference configuration. By storing the difference configuration of different versions of software through the electronic controller, the same set of software can be adapted to a variety of vehicle models and configuration requirements, without the need to maintain software separately for each vehicle model, reducing the number of software, thereby reducing the complexity of the version software, and further improving the user experience and vehicle performance.

[0050] In some implementations, the difference configuration includes parameter configuration and function configuration, and different storage methods can be configured to store software versions, parameter configurations, and function configurations.

[0051] As an implementation mode, the electronic controller stores the correspondence between the software version, parameter configuration and function configuration, and step 120 specifically includes: determining the corresponding target parameter configuration and target function configuration according to the software version to be switched and the correspondence.

[0052] For example, the corresponding relationship between software version, parameter configuration and function configuration is shown in Table 2.

[0053] Table 2

[0054] Software Version Parameter configuration Function Configuration EVR01 Battery voltage 1 Passenger seat heating function EV01 Battery voltage 2 No passenger heating function

[0055] In some embodiments, the correspondence between software version, parameter configuration and function configuration also includes the correspondence between switch quantity and software version. The electronic controller can determine the switch quantity of each switch according to the software version to be switched, determine the parameter configuration with the switch quantity as on as the target parameter configuration, and determine the corresponding target function configuration according to the correspondence.

[0056] As another embodiment, the electronic controller stores a first correspondence between the software version and the parameter configuration, and a second correspondence between the parameter configuration and the function configuration. Step 120 specifically also includes: determining the corresponding target parameter configuration based on the software version to be switched and the first correspondence; determining the corresponding target function configuration based on the target parameter configuration and the second correspondence.

[0057] For example, the first correspondence between the software version and the parameter configuration is shown in Table 3, and the second correspondence between the parameter configuration and the function configuration is shown in Table 4.

[0058] Table 3

[0059] Software Version Parameter configuration EVR01 Battery voltage 1 EV01 Battery voltage 2

[0060] Table 4

[0061] Parameter configuration Function Configuration Battery voltage 1 Passenger seat heating function Battery voltage 2 Heated windshield function

[0062] In some embodiments, the first correspondence also includes a correspondence between the switch quantity and the software version. The electronic controller can determine the switch quantity of each switch according to the software version to be switched, determine the parameter configuration when the switch quantity is on as the target parameter configuration, and determine the corresponding target function configuration according to the second correspondence.

[0063] In the scenario of vehicle electrical inspection offline, vehicle software configuration is performed, and the electronic controller communicates with the electrical inspection device, such as Figure 3 As shown, step 110 specifically also includes:

[0064] Step 111: Receive and store the vehicle configuration word sent by the electric inspection device.

[0065] In some embodiments, the electronic controller establishes a connection with the electrical inspection device. After the connection is successfully established, the electrical inspection device sends a vehicle configuration word, which includes vehicle information and the software version to be switched. The electronic controller receives and stores the vehicle configuration word sent by the electrical inspection device.

[0066] For example, the configuration word of the vehicle is 2E F0 10 01, wherein the seventh and eighth bits 01 of the configuration word represent the EVR model, that is, the software version to be switched.

[0067] Step 112: Identify the configuration word and obtain the software version to be switched.

[0068] In some implementations, the electronic device may identify the configuration word to obtain the software version to be switched, and then perform configuration switching according to steps 120 - 130 .

[0069] For example, the configuration word is 2E F0 10 01, and the electronic device can identify the seventh and eighth bits of the configuration word, 01 represents the EVR vehicle model, and obtain the software version to be switched (EVR vehicle model software version).

[0070] After step 130, the method further includes:

[0071] Step 140: Send the stored configuration word to the electric inspection device, so that the electric inspection device determines whether the difference configuration corresponding to the current software version is successfully switched to the target difference configuration according to the configuration word sent by itself and the configuration word received.

[0072] It should be noted that in the process of the electrical inspection device sending configuration words to the electronic controller, the configuration word received by the electronic controller may be different from the configuration word sent by the electrical inspection device due to signal interference, hardware failure, network problems, etc. Therefore, the electrical inspection device needs to determine whether the difference configuration corresponding to the current software version has been successfully switched to the target difference configuration based on the configuration words sent by itself and the configuration words received.

[0073] In order to perform the corresponding steps in the above embodiments and various possible methods, a device implementation method is given below.
