Therefore, the embodiment of the application provides an ECU upgrading scheme, which can rapidly and conveniently upgrade the software of the electronic control unit and reduce misoperation caused by manual intervention.
The embodiment of the application discloses an ECU upgrading method applied to a target vehicle machine application, and referring to fig. 1, the method comprises the following steps:
step S11: the method comprises the steps of obtaining a vehicle identification of a target vehicle and original software version information of at least one ECU, uploading the information to a server, so that the server can determine a target ECU needing to be upgraded from the at least one ECU based on the vehicle identification and the original software version information, and sending an ECU software upgrading package of the target ECU to a target vehicle machine application.
In the embodiment of the present application, the Vehicle identifier may be a Vehicle VIN code (Vehicle Identification Number); the target vehicle machine application is application software configured in a vehicle machine for the vehicle.
In the embodiment of the application, the vehicle identification of the target vehicle and the original software version information of the at least one ECU are sent to the server through a vehicle-mounted WIFI (Wireless-Fidelity) or 4G or 5G network.
In the embodiment of the present application, the determining, by the server, a target ECU that needs to be upgraded from the at least one ECU based on the vehicle identifier and the original software version information specifically includes: so that the server determines the latest software version information of the at least one ECU based on the vehicle identification and the original software version information; comparing the original software version information and the latest software version information of the at least one ECU, and determining the ECU with inconsistent comparison as a target ECU needing to be upgraded.
Step S12: and receiving the ECU software upgrading packet of the target ECU sent by the server.
Step S13: and upgrading the target ECU based on the ECU software upgrading package.
In the embodiment of the application, the ECU is upgraded by using the target vehicle machine application without manual upgrading, so that the method is quicker and more convenient, the time of a vehicle owner is saved, and misoperation caused by manual intervention is reduced.
In this embodiment of the present application, after the target ECU is upgraded based on the ECU software upgrade package, the method further includes: updating the software version information of the target ECU as latest software version information based on the ECU software upgrade package. It should be noted that the target vehicle application stores the latest software version information of the current ECU for subsequent determination of whether the corresponding target ECU needs to be upgraded.
In this embodiment of the present application, if there is more than one target ECU, the upgrading the target ECU based on the ECU software upgrade package includes: determining multiple threads which are configured for upgrading in advance; and upgrading the target ECU simultaneously through the multithreading and based on the ECU software upgrading package. It should be noted that, when there are multiple target ECUs to be upgraded, the multiple target ECUs to be upgraded can be upgraded simultaneously through the multithreading; it is noted that when the number of threads is less than the number of target ECUs that need to be upgraded, the threads may be temporarily added for the upgrade to be performed simultaneously.

In this embodiment of the present application, if there is more than one target ECU, the upgrading the target ECU based on the ECU software upgrade package includes: determining the priority of the target ECU according to the influence degree on the vehicle safety; and upgrading the target ECU in sequence based on the priority.
It should be noted that different ECUs have different degrees of influence on vehicle safety, and when there are a plurality of target ECUs that need to be upgraded, the plurality of ECUs may be arranged from large to small according to the degrees of influence on vehicle safety to determine the priority for upgrading the original electronic control unit software. It should be noted that the upgrade influence degree is small after the upgrade influence degree is large as far as possible, so that the influence on the safety of the vehicle is prevented.
It should be noted that, when the number of threads is less than the number of target ECUs that need to be upgraded and the number of threads cannot be increased, the degree of influence of upgrading is large first and then the degree of influence of upgrading is small according to the priority. In one embodiment, if the number of threads is 3 and the number of target ECUs is 5, the target ECU of the first 3 priority levels is upgraded first, and the remaining two target ECUs are upgraded later. It should be noted that the upgrade completion times of the first 3 target ECUs may be the same or different, if one of the target ECUs is upgraded first, the target ECU with the fourth priority is upgraded continuously, and if the other target ECU is upgraded, the target ECU with the fifth priority is upgraded.

In an embodiment of the present application, the acquiring and uploading a vehicle identifier of a target vehicle and original software version information of at least one ECU to a server includes: and automatically acquiring the vehicle identification of the target vehicle and the original software version information of at least one ECU at regular time according to a preset time interval and uploading the information to a server. In one embodiment, different preset time intervals can be determined according to the existence time of the ECU in the target vehicle, the preset time interval corresponding to the ECU with shorter existence time is a longer time interval, and the preset time interval corresponding to the ECU with shorter existence time is a shorter time interval; specifically, a target time is set; setting a preset time interval corresponding to the original electronic control unit software with the existing time longer than the target time as a first preset time interval; setting a preset time interval corresponding to the original electronic control unit software with the existing time less than the target time as a second preset time interval; the first preset time interval is smaller than the second preset time interval.
