Example two
In order to further explain the practical effect of the vehicle OTA state intelligent analysis processing of the invention, the embodiment discloses a vehicle OTA state intelligent analysis processing method and an application scenario realized based on the first embodiment.
Referring to fig. 2, the vehicle OTA state intelligent analysis processing method provided by the embodiment includes three aspects.
First, vehicle end OTA information acquisition stage
The OTA information is collected when the OTA of the vehicle is upgraded, the VIN code of the vehicle and the version information of the controller software are uploaded to the cloud OTA state analysis unit when the OTA of the vehicle succeeds or is abnormal, and an abnormal log is also uploaded when the OTA of the vehicle is abnormal.
Second, cloud OTA state analysis stage
The method comprises the steps that firstly, the cloud side collects the uploaded information, if the uploaded OTA software version is consistent with a target version, the OTA software version is considered to be successfully upgraded, and the total push vehicle, the successfully upgraded vehicles and the OTA success rate are counted;
secondly, if the OTA abnormal information is found, the system automatically sends an email to an OTA administrator, and the OTA abnormal information is known and processed at the first time;
thirdly, for the information of the OTA abnormity which is not confirmed, the information is firstly summarized according to the abnormal version number preliminarily, an OTA administrator arranges a developer to check an abnormal log on the system, after the abnormal reason is determined, an abnormal category is newly established in the system, the abnormal reason and an abnormal log comparison rule are noted (if the log contains a keyword XXX, the log is regarded as the same type of abnormity);
and fourthly, the system analyzes the abnormal logs in sequence according to the comparison rule of the abnormal logs, if the comparison rule is met, the abnormal information state is changed into confirmed state, and if the comparison rule is not met, the abnormal information state is still classified as unconfirmed abnormal. Repeating the third and fourth steps until all the abnormal information is confirmed.
Third, cloud OTA exception handling stage
For each exception category that has been validated, a solution is validated by the developer and added to the existing exception category. If the abnormity can be solved through OTA again, the updating packet can be uploaded to the abnormity processing unit again, and the upgrading packet is automatically pushed to the abnormal vehicle again through the acquired vehicle VIN code by the system; if the solution can not be solved through OTA, the system pushes the solution mail to the operation and maintenance personnel, and the operation and maintenance personnel contacts the owner of the vehicle to carry out offline processing.
Therefore, if the user who carries out OTA subsequently encounters the same problem, the user can be automatically identified by the existing abnormal category in the system and automatically processes the abnormal category. The system has learning ability, realizes the purpose of automatically analyzing and processing problems in the later period by manually maintaining the abnormal analysis processing rule in the earlier period, and reduces the labor cost and the OTA upgrading risk.
