Description

Technical Field

[0001] This invention relates to the field of new energy commercial vehicle technology, and specifically to a method for monitoring the software version of a new energy commercial vehicle controller. Background Technology

[0002] New energy commercial vehicles lack controller software version monitoring functionality. To determine whether the actual vehicle controller software version matches the software version released by the data management platform, a diagnostic tool must be connected to read the actual vehicle version and then compared with the software version on the data management platform. Software version mismatches may only be exposed during the debugging phase, resulting in a certain lag. It is difficult to detect unauthorized modifications to the software of the monitored object after the vehicle leaves the factory.

[0003] When a vehicle rolls off the production line, it cannot automatically determine whether the software version of the monitored object and the software version of the data management platform are consistent; after the vehicle leaves the factory, if the controller software is changed, the vehicle manufacturer will not be aware of it. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a method for monitoring the software version of a new energy commercial vehicle controller.

[0005] The technical solution adopted by this invention to solve its technical problem is: a method for monitoring the software version of a new energy commercial vehicle controller, comprising the following steps:

[0006] S1: Monitoring the software version monitoring function developed by the monitoring entity;

[0007] S2: The monitored object reports its own software version information;

[0008] S3: The display device completes the design for displaying information about software version inconsistencies;

[0009] S4: The writing device completes the writing of the software version comparison value.

[0010] Preferably, the monitoring entity develops a software version monitoring function for the new energy vehicle controller to design a software version request function and receive software version information from the monitored object according to the specified message ID and data format. At the same time, it designs and stores the software version information of the monitored object obtained from the data management platform and written by the diagnostic instrument.

[0011] Preferably, the monitoring object feeds back its own software version information by receiving a software version request message sent by the monitoring subject and feeding back its own software version information to the monitoring subject in a prescribed data format.

[0012] Preferably, the display device is designed to display software version inconsistency information by having the instrument parse the software version inconsistency information received from the new energy vehicle controller as a controller software version inconsistency according to the prescribed display content and parsing method.

[0013] Preferably, after the writing device completes the writing of the software version comparison value for the vehicle to be taken off the production line, it uses a diagnostic tool to obtain the software version information of the monitored object from the data management platform based on the vehicle information, and writes it to the new energy vehicle controller through the diagnostic service.

[0014] The present invention has the following beneficial effects: it can quickly identify the matching status of vehicle controller software version in the production and after-sales stages, which facilitates quick problem location, improves the efficiency of fault diagnosis in production and after-sales, and can also restrict suppliers from privately rewriting programs, ensuring the consistency of vehicle performance, which is a soft benefit.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, a method for monitoring the software version of a new energy commercial vehicle controller includes the following steps:

[0020] S1: Monitoring Entity 2 Software Version Monitoring Program

[0021] The new energy vehicle controller 21 is designed with a software version request function and receives software version information from the monitored object 4 according to the specified message ID and data format. At the same time, it is designed to store the software version information of the monitored object 4 obtained from the data management platform and written by the diagnostic instrument 31. Specifically, it completes the function of storing the software version comparison value of the monitored controller, which is not lost when power is off; each time the vehicle key is powered on, it uses a specific event-type message to request the software version of the monitored controller and temporarily stores the software version fed back by the monitored controller, which is lost when power is off; when it detects that the stored software version comparison value is inconsistent with the value fed back by the monitored object 4 controller, it sends the comparison result to the display device 1.

[0022] S2: Monitored object 4 reports its own software version information.

[0023] After receiving the software version request message sent by the monitoring subject 2, the monitored object 4 replies with its own software version information to the monitoring subject 2 in accordance with the prescribed data format.

[0024] S3: Display device 1 completes the design for displaying software version inconsistency information.

[0025] Instrument 11 interprets the software version inconsistency information received from the new energy vehicle controller 21 as a software version inconsistency of a certain controller, according to the prescribed display content and parsing method.

[0026] S4: Write device 3 completes writing of the software version comparison value.

[0027] After the vehicle rolls off the production line, the diagnostic tool 31 uses the vehicle information to obtain the software version information of the monitored object 4 from the data management platform and writes it into the new energy vehicle controller 21 through the diagnostic service.

[0028] like Figure 2 As shown, the control flow of this invention is as follows:

[0029] When the vehicle rolls off the production line, the diagnostic tool 31 obtains the control software version information of the monitored object 4 from the data management platform and writes it to the vehicle controller 21. If the vehicle key is in the ON position, the vehicle controller 21 sends a software version request message three times. The vehicle controller 21 compares the software version information fed back by the monitored object with the written information. If they match, the process ends. Otherwise, the instrument panel 11 displays that the software versions of the transmission controller 41, motor controller 42, battery management system 43, or intelligent integrated controller 44 in the monitored object 4 are inconsistent.

[0030] This invention is not limited to the above-described embodiments. Anyone should know that any structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention.

[0031] The technologies, shapes, and structures not described in detail in this invention are all known technologies.
