step S130, the target data is sent to the terminal;
step S140, acquiring parameters to be inspected and data extraction conditions corresponding to the parameters to be inspected according to the second fault inspection data when the second fault inspection data sent by the terminal are received within a preset time interval, wherein the parameters to be inspected are selected from the set inspection parameters;
step S150, updating the set checking parameters by using the parameters to be checked, and updating the data extraction conditions by using the data extraction conditions.
In this embodiment, after acquiring target data according to first failure investigation data and sending the target data to the terminal, in a preset time interval, the terminal may change investigation parameters and data extraction conditions corresponding to the investigation parameters according to returned target data, select parameters to be investigated from the set investigation parameters, obtain parameters to be investigated, and determine data extraction conditions corresponding to the parameters to be investigated; and then sending the parameters to be checked and the conditions for extracting the data corresponding to the parameters to be checked to an electronic controller. And the electronic controller adopts the parameter to be checked to update the set checking parameter and adopts the data condition to be extracted to update the data extraction condition, and returns to execute the step of extracting target data corresponding to the set checking parameter meeting the data extraction condition from a pre-established parameter variable list and sending the target data to the terminal.

In the technical scheme of the embodiment, because the parameters to be inspected and the data extraction conditions corresponding to the parameters to be inspected are acquired according to the redetermined second fault inspection data within the preset time interval, the target data are extracted according to the parameters to be inspected and the data extraction conditions corresponding to the parameters to be inspected, and the fault inspection capability is improved by dynamically changing the inspection parameters and the data extraction conditions of the parameters to be inspected.

The parameter index information can be a parameter number or a parameter serial number; the parameter number may consist of letters, underlines or numbers; for example, the parameter numbers may be temperature_1, establishment_y, voltage_kl15, and the like.
According to the technical scheme, the embodiment adopts the parameter index information corresponding to the set investigation parameter; extracting detection data corresponding to the parameter index information from the parameter variable list; and determining target data based on the data extraction conditions and the detection data, thereby achieving the purpose of extracting the target data from the parameter variable list.
As shown in fig. 5, in a fourth embodiment of the present application, when the method for acquiring detection data of the present application is applied to a terminal, the method includes the following steps:
step S210, determining first troubleshooting data, wherein the first troubleshooting data comprise set troubleshooting parameters and data extraction conditions of the set troubleshooting parameters;
step S220, sending the first troubleshooting data to a vehicle controller, where the vehicle controller receives the first troubleshooting data sent by the terminal, extracts target data corresponding to the set troubleshooting parameters meeting the data extraction condition from a pre-established parameter variable list, and sends the target data to the terminal.

Specifically, the data extraction condition can be determined according to the parameter index information of the set investigation parameter and the preset investigation threshold value of the set investigation parameter; when the target data returned by the terminal changes, the investigation parameters can be redetermined according to the target data. When the investigation parameters are changed, the parameter index information corresponding to the investigation parameters in the data extraction conditions and the preset investigation threshold value of the investigation parameters are correspondingly changed. After first troubleshooting data are determined, the first troubleshooting data are sent to a vehicle controller through a wireless network, wherein the vehicle controller receives the first troubleshooting data sent by a terminal, extracts target data corresponding to the set troubleshooting parameters meeting the data extraction conditions from a pre-established parameter variable list, and sends the target data to the terminal.
Under other application scenes, the terminal can analyze the target data when receiving the target data fed back by the vehicle controller so as to obtain a fault analysis result; specifically, detection data of the vehicle speed or the temperature may exist in the target data at the same time; therefore, after obtaining the target data, the terminal needs to further analyze the target data to determine a fault analysis result; after obtaining the result of the fault analysis, for example, after determining that the fault is caused by temperature, the detected data of the vehicle speed may be screened out, and only the detected data related to the temperature may be retained; and further modifying the data extraction condition according to the detection data so as to improve the vehicle fault performance evaluation capability.
