Background

At this time, many vehicle factories' ECU (Electronic Control Unit ) products have a normal operation mode and an EOL (End Of Life) down-line operation mode. These factories will all make EOL final tests on products produced by themselves. The final purpose of EOL detection is to make a final process check for the product, including information such as the function, version number, factory setting, etc. of the product, so as to prevent customer complaints and even personal safety problems caused by product failure. The checking of the version number of the product is a necessary check, which relates to whether the product is successfully written or whether the satisfactory version is written.

It is known that EOL detects a version number by reading it by DID (Data Identifier) in UDS (Unified Diagnostic services, unified diagnostic service), but most factories read a software version number. Typically, the product software needs to be written after a Bootloader boot has been executed. The Bootloader of this Bootloader is also version number, and it needs to be checked for version number. Especially when the brushing process has a problem, the Bootloader of the product needs to be optimized and changed, and the change of the Bootloader version is involved; or if there is a product returned from the client, it is necessary to check which version the Bootloader belongs to, which time period to perform the writing operation or production, to confirm the point of time when the problem occurs. However, the prior art lacks a query way for Bootloader version numbers.

The first predetermined operation includes one of a single click, a double click, a long press, a slide, and a box selection.

Of course, the current version information is not limited to the version information of Bootloader, but may be other software and hardware version information of the controller.

According to an exemplary embodiment of the present application, in response to a first predetermined operation acting on a target node, displaying an initial interface including a first operation region and a second operation region, includes: in response to the first predetermined operation, displaying the initial interface including the first operation region, the second operation region, and a third operation region as shown in fig. 5, the third operation region including a third selection identifier 300, a plurality of third display regions 301, and a plurality of fourth display regions 302, the method further comprising: acquiring a plurality of the history version numbers and a corresponding plurality of the release dates in response to a fourth predetermined operation acting on the third selection identifier 300; the history version numbers are displayed in one-to-one correspondence in each of the third display areas 301, and the release dates are displayed in one-to-one correspondence in each of the fourth display areas 302. According to the first preset operation, an initial interface comprising a first operation area, a second operation area and a third operation area is displayed, and then according to preset operation on a third selection mark of the third operation area, all version numbers and corresponding release dates of the target controller are obtained, and the version information is displayed in a display area corresponding to the third operation area, so that operators can conveniently check the version numbers and the corresponding release dates of all stages of the target controller.

In addition, in addition to the third selection identifier, the plurality of third display areas and the plurality of fourth display areas, as shown in fig. 5, the third operation area further includes first character information 303, second character information 304, third character information 305, a plurality of fourth character information 306 and a plurality of fifth character information 307, where the first character information 303 is located at one side of the third selection identifier 300, the first character information 303 is character information indicating a function of the third selection identifier 300, such as "display XXX all history version and release date", the second character information 304 is located at one side of the third display area 301, the second character information 304 is used to indicate that the corresponding third display area 301 is an area of a version number of the display controller, the third character information 305 is located at one side of the fourth display area 302, the third character information 305 is used to indicate a release date of the corresponding version number of the display controller, the second character information 304 is located at one side of the fourth display area 306, the fourth character information 306 is located at the other side of the fourth display area 301, and the remaining one side of the fourth display area is used to indicate a release date of the fourth version number of the display controller, and the remaining display area is used to indicate a version number of the fourth display area 301.

In an actual application process, the fourth predetermined operation includes one of single click, double click, long press, sliding and box selection.

The third display area and the fourth display area may be displayed on the initial interface in a text box form, or may be displayed on the initial interface in other forms.

To further solve the problem of lack of query means for the version number of the controller in the prior art, in another specific embodiment of the present application, before responding to the first predetermined operation acting on the target node, the method further includes: as shown in fig. 7, establishing a CAN communication connection between the terminal and the target controller; adding an initial node in the CANoe software, and configuring a CAPL browser and a panel of the initial node; and correlating the configured CAPL browser with the configured panel to obtain the test node. The version information of the controller is subjected to change management through the CAPL script and the panel form, so that a test interface is obtained, the read version information of the controller can be intuitively displayed through the panel, the inquiry of the version number is further realized, the release information of the version is not required to be inquired from other files, and the working efficiency of operators is further improved.

It should be noted that, in general, EOL off-line detection is to detect power supplied by a single controller, and the scheme is based on a certain ECU in the whole pile.

Step S202 of controlling the target controller to enter the EOL mode in response to a second predetermined operation acting on the first operation region;

specifically, as shown in fig. 3, the first operation area includes a first selection identifier 200 for entering the EOL mode and a first indicator lamp identifier 201, where the first selection identifier may be a checkbox or may be another selection identifier, and the first indicator lamp identifier has two states of on and off, and the first indicator lamp identifier is on when the target controller enters the EOL mode. The second predetermined operation may include one of a single click, a double click, a long click, a slide, and a box selection.

In addition to the first selection identifier and the first indicator light identifier, as shown in fig. 3, the first operation area further includes sixth character information 202 and seventh character information 203, where the sixth character information 202 is located on one side of the first selection identifier 200 and is used to illustrate the function of the first selection identifier 200, and if the sixth character information is "XXX controller enters EOL mode", the seventh character information 203 is located on one side of the first indicator light identifier 201 and is used to illustrate the meaning represented by the first indicator light identifier 201 being lit, and the seventh character information may be "XXX controller enters EOL successfully".

To further facilitate an operator determining whether a target controller has entered EOL mode, in one alternative, controlling the target controller to enter EOL mode in response to a second predetermined operation acting on the first operating region includes: responding to the second preset operation acting on the first selection identifier, and sending a first request message to the target controller, wherein the first request message is a message for controlling the target controller to enter the EOL mode; and under the condition that a first response message fed back by the target controller is received, the first indicator lamp mark is lightened, and the first response message is a message representing that the target controller enters the EOL mode. According to a second preset operation, a first request message for controlling the target controller to enter the EOL mode is sent to the target controller, so that the target controller responds to the first request message to enter the EOL mode and returns a first response message for successfully entering the EOL mode.

In practical applications, the first selection identifier and the first indicator light identifier are designed as system variables. Using an on sysvar function in the CAPL script, responsive to the system variable, the corresponding CAPL script processing logic is 1 upon detecting that the first selection identifier is checked. And when the first response message is detected, setting the CAPL script logic of the first indicator lamp identification to be 1, and immediately turning on the first indicator lamp identification to indicate that the EOL mode is successfully entered.

In a specific embodiment, sending a first request message to the target controller includes: periodically sending a first sub-request message to the target controller; under the condition that a first sub-response message fed back by the target controller in response to the first sub-request message is received, canceling the transmission of the first sub-request message, and starting to periodically transmit a second sub-request message to the target controller; and under the condition that a second sub-response message fed back by the target controller in response to the second sub-request message is received, canceling the transmission of the second sub-request message, and starting to periodically transmit a third sub-request message. And under the condition that a first response message fed back by the target controller is received, the first indicator lamp mark is lightened, and the method comprises the following steps: and under the condition that a third sub-response message fed back by the target controller in response to the third sub-request message is received, the first indicator lamp identifier is lightened.

The following are illustrated: in the case that the target controller is a T-BOX, three frames of messages need to be sent to the T-BOX, and when each frame of messages is responded correctly, the T-BOX enters EOL mode. The corresponding message is as follows:

transmitting first frame message

ID:18E002F1h CT:10000DLC:8

Data:55h 41h 46h 43h 33h 01h FFh DCh

After the transmission is finished, under the condition that the feedback message 1 is received:

ID:18E0F102h Data:55h 41h 46h 43h 33h AAh FFh 77h

cancelling the transmission of the first frame message and transmitting the second frame message:

ID:18E002F1h CT:10000DLC:8

Data:55h 41h 46h 43h 33h 02h FFh DFh

after the transmission is finished, under the condition that the feedback message 2 is received:

ID:18E0F102h Data:55h 41h 46h 43h 33h BBh FFh 66h

canceling the sending of the second frame message and sending a third frame message:

ID:18E002F1h CT:10000DLC:8

Data:55h 41h 46h 43h 33h 03h FFh DEh

after the transmission is finished, under the condition that the PC receives the feedback message 3:

ID:18E0F102h Data:55h 41h 46h 43h 33h CCh FFh 11h

indicating successful entry into EOL mode.

And when the first selection identifier is detected to be checked, the corresponding CAPL script processing logic is 1, and then a first frame message is sent. Then using an on message function to respond to the message 18E0F102h, and sending a second frame sending message when detecting that the message content is the feedback message 1; when detecting that the message content is feedback message 2, sending a third frame sending message; when detecting that the message content is feedback message 3, the CAPL script logic of the first indicator lamp identification is set to be 1, the lamp is immediately electrically turned on, and the EOL mode is successfully entered. When not hooked, the lamp logic processes to 0 in CAPL, and the lamp remains off, meaning no message is sent out and the EOL mode is not entered.

Step S203, in the case that the target controller enters the EOL mode, responding to a third preset operation acted on the second operation area to obtain the current version information;

specifically, as shown in fig. 4, the second operation area includes a second selection identifier 204 for querying the current version information, the second operation area further includes a first display area 205 for displaying a version number, a second display area 206 for displaying the release date, and a plurality of second indicator light identifiers 207, the second indicator light identifiers 207 correspond to version states of new version, old version, and unclear state one by one, and the third predetermined operation may include one of a single click, a double click, a long click, a slide, and a box. The second selection identifier may be a check box or other selection identifiers, the first display area and the second display area may be text boxes, and may be displayed on a panel in other formats, and the second indicator identifier has two states of on and off, where when the second indicator identifier is on, the current version information is indicated to be the version state corresponding to the second indicator identifier.

In addition to the information, as shown in fig. 4, the second operation area further includes eighth character information 208, ninth character information 209, tenth character information 210, eleventh character information 211, and a plurality of twelfth character information 212, where the eighth character information 208 is located at one side of the second selection identifier 204 and is used to describe a function of the second selection identifier 204, and if the eighth character information 208 is "XXX controller version number read"; the ninth character information 209 is located at one side of the first display area 205, the ninth character information 209 is used for explaining that the first display area 205 is an area for displaying a current version number of the controller, the third character information 210 is located at one side of the second display area 206, and the third character information 210 is used for explaining that the corresponding second display area 206 is an area for displaying an issue date of the current version number of the controller; the eleventh character information 211 is located on the same side of the plurality of second indicator light identifiers 207, and is used for explaining meaning represented by the lighting of the second indicator light identifiers 207, the eleventh character information 211 may be "new and old version judgment", the twelfth character information 212 is located on one side of the second indicator light identifiers 207 in a one-to-one correspondence manner, and the twelfth character information is an explanation of the version state.

In an alternative, the obtaining the current version information in response to a third predetermined operation acting on the second operation area includes: transmitting a second request message for reading the current version information to the target controller in response to the third predetermined operation acting on the second selection identifier; receiving a second response message of the target controller, wherein the second response message carries information representing the current version information; and determining the current version information according to the second response message. And by operating the second selection identifier, the version information of the target controller including the current version of the Bootloader can be inquired and obtained, and the effect of inquiring the version information more simply and conveniently is further realized.

And the second selection identifier, the first display area, the second display area and the three first indicator lamp identifiers are processed into system variables, and when the second selection identifier is checked, the second selection identifier is correspondingly processed into logic 1 in the CAPL script, and an instruction for reading the current version number is started to be sent.

Further, determining the current version information according to the second response message includes: analyzing the second response message to obtain a target version number, wherein the target version number is the current version number of the target controller; determining whether a history version number identical to the target version number exists in the history information according to the target version number and the history information, wherein the history information comprises a plurality of history version numbers of the target controller and release dates of the history version numbers, and the history version number is one of the history version numbers; when the history version number exists in the history information, determining that the release date corresponding to the history version number is a target release date of the target version number, determining a version state of the target version number according to the target release date and a plurality of release dates, determining that the version state is a new version when the target release date is the latest of a plurality of release dates, and determining that the version state is an old version when the target release date is not the latest of a plurality of release dates; in the event that the history version number is not present in the history information, the version state of the target version number is determined to be an unclear state.
