Step S2: configuring a task threshold, setting a fusing condition and issuing an upgrade task;
configuring the task threshold includes: defining a threshold parameter for a part of the automobile, and configuring a threshold formula according to the threshold parameter;
in practical application, the configuration task threshold generates a configuration file, and the configuration file is uploaded to a system for storage.
In practical application, the automobile parts are all parts related to ECU in the upgrading of automobile OTA, including video entertainment domain controller, blind area monitoring system module assembly and central gateway, etc., the upgrading task corresponds to the automobile parts, each part also has respective part number, the corresponding relation between part name and upgrading task can refer to table 2,
table 2: correspondence table for part name upgrading task
In practical applications, the defined threshold parameters are combined with operators, and the threshold formulas are configured according to the characteristics of the vehicle parts, for example: error information with serious abnormal level of the part represented by E1 and error information with ordinary abnormal level of the part represented by E2 are used, symbols such as < >, =,.ltoreq.and more are used, and a threshold formula is flexibly configured through preset threshold parameters and operators.
In practical applications, the terms used for the threshold formula configuration are as follows:
task_name: representing a "task name";
task_record: representing "task blown", a value of "01" representing blown; "02" represents normal execution tasks;
ecu_name: representing "part name";

Fusing condition 1 may be configured to:
fusing condition 1=fusing condition a or fusing condition b, meaning that fusing condition 1 is triggered whenever either fusing condition a or fusing condition b is triggered.
Fusing condition 2 = undetected and detection failure and download failure and installation incomplete and upgrade precondition is not satisfied.
Fusing condition 2 may be configured to:
fusing condition 2=fusing condition a and fusing condition b, meaning that fusing condition 2 will be triggered only if fusing condition a and fusing condition b are triggered simultaneously.
Step S3: the method comprises the steps of obtaining version information of a vehicle and matching an upgrading task for the vehicle;
