Specifically, the vehicle can upload the latest software and hardware versions of the ECU to a whole vehicle software and hardware version management system through the OTA server, and update a vehicle ECU information table. For example, when activating the function FUN9 for a fee, it is first checked which ECUs of the vehicle are mapped by FUN 9. Whether the software of these ECUs has been flushed (whether there is a FUN9 function), and if it has been flushed but not activated, generate an instruction to the OTA server to activate FUN 9. The OTA server issues to the vehicle interior ECU activation function FUN 9. And according to the feedback information of the vehicle-mounted terminal, the activation state of the function FUN9 in the vehicle ECU information table is changed from Inactive to Active.
In one embodiment, step S11: at least one vehicle ECU to obtain OTA function mapping upon successful OTA function purchase, previously comprising: acquiring activation state information of an OTA function when receiving a use request of the OTA; when the OTA function is in an activated state, starting the OTA function; and when the OTA function is in an inactivated state, displaying an OTA function purchasing interface through a terminal display screen.

Specifically, the entire vehicle software and hardware version management system judges whether the ECU in the vehicle needs to be updated or not according to the vehicle identification information and the purchased OTA function code. And the whole vehicle software and hardware version management system acquires the ECU mapped by the OTA function according to the OTA function code. When the ECU mapped by the OTA function in the vehicle ECU information table of the corresponding vehicle has the corresponding OTA function code, the OTA function in the ECU in the vehicle can be directly activated, and the ECU mapped by the OTA function in the vehicle does not need to be updated. When the ECU which does not correspond to the OTA function code exists in the ECUs which are mapped by the OTA function in the vehicle ECU information table of the corresponding vehicle, the ECU which does not have the OTA function code needs to be updated, and the purchased OTA function is written.
Step S13: if so, an OTA function in the vehicle ECU is activated.
In one embodiment, step S13: if so, activating an OTA function in the vehicle ECU, including: generating an instruction for activating the OTA function to an OTA server; the OTA server sends an instruction to the vehicle interior ECU to activate the OTA function.
Specifically, the entire vehicle software and hardware version management system confirms that the corresponding OTA function (e.g., FUN5) software in each ECU of the vehicle is only not activated. An instruction to activate FUN5 is generated to the OTA server. The OTA server issues to the vehicle interior ECU activating the FUN5 function in the ECUs 3, 4, 5 (see table 2).
Step S14: and if the OTA function does not exist, generating an OTA function flash task to the corresponding ECU, and activating the OTA function after the ECU is updated.
Specifically, the automobile manufacturer may issue new functions periodically. For example, the software of the ECU6 is released, and the version is ECU6_ V1.2. The corresponding functions are as follows:
ECU6_V1.2 ECU6 FUN11、FUN12
after clicking the purchase function FUN11 in the function purchase store of the mobile phone APP or the vehicle-mounted large screen by the user. Looking at the ECU mapped by FUN11, we get FUN11 mapped ECU 6. The current ECU6 of the vehicle does not have software corresponding to the flush function FUN 11. The entire vehicle software and hardware version management system generates a flash task, so that the ECU6 corresponding to the vehicle is updated, and the function FUN11 in the ECU6 is only not activated. After the update is completed, an activation instruction is generated to activate the function FUN11 of the vehicle interior ECU 6.
The OTA function purchasing and activating method provided by the invention establishes the information table of each ECU for each vehicle.
