S303: and judging whether the dynamic stack of the software of the electronic control unit overflows or not according to the maximum utilization rate of the dynamic stack.
In the embodiment of the present application, the EMS in fig. 2 is specifically used for explanation, specifically, a software dynamic stack utilization rate state data flow is shown in fig. 4, and a detailed description of a specific test scheme is as follows:
according to the schematic diagram of the test system and the construction steps in FIG. 2, after the physical device is connected, the KL30 and KL15 switches are turned on; after a Lodobach debugger is adopted to burn a test program into EMS for running, a script 'stack _ coverage 1. cmm' is run in a Trace32 window of the debugger to carry out circulation state statistics on the program in the dynamic running process, and data is stored into a path corresponding to a formulated test computer in a binary file (.bin) mode; performing more than three rounds of simulated energy supplement and stopping running the 'stack _ covergae1. cm' script after the charging process is finished, running the batch processing script 'T32 _ Simlulator. bat' to enter a 'Simlulator' mode of a debugger, and automatically opening a 'Simlulator' mode window of a Trace32 program after the running is successful; and (3) running a script "stack _ covergae2. cmm" in a "Simtemplate" mode window of the Trace32 program to analyze, process and count the collected multiple binary files and store the statistical result in a percentage format in a csv file format to a disk specified path of the upper computer.
The process can be summarized as follows:
step 1: after the test device is built, a system is powered on to run a 'stack _ covergae1. cm' script;
step 2: after the energy supplementing and charging process is simulated for more than three times, the operation of a 'STACK _ coverage 1. cm' script on a debugger is stopped, and data are transmitted to the Latt Bach debugger from a STACK area of a tested electrical control unit (EMS) and then are stored under a corresponding preset path of a computer hard disk;
and step 3: importing the 'config _ sim.t 32' file into a preset test computer disk path to run a 'T32 _ Simlulator.bat' script to enter a debugger offline mode;
and 4, step 4: and running a 'stack _ covergae2. cm' script, importing each binary file collected and stored by the 'stack _ covergae1. cm' script into a debugger for traversing statistical calculation, and importing a calculation result into another preset upper computer disk path in a csv file format.
It should be further noted that, as described in the above test steps, the embodiment of the present application includes 2 debugger control scripts, 1 batch script, and 1 debugger mode state change configuration file. The 'STACK _ covergae1. cm' file is a first debugger control script and is mainly responsible for acquiring states of tested electrical control unit software STACK in a dynamic running process in a normal online mode of a debugger and saving the state information in a binary file format into a corresponding file path of a hard disk of a testing computer, and the work of the 'STACK _ covergae2. cm', the batch processing script ('T32 _ Simtemplate. bat'), and the work of a debugger mode state change configuration file ('config _ sim.t 32') are completely independent, because the operation of the 'STACK _ covergae1. cm' file does not depend on the operation of the following working products. The work of 3 products such as "stack _ cover 2. cmm", "T32 _ Simfluor. bat" and "config _ sim.t 32" has a pre-consequence relationship, and meanwhile, the statistical input source of "stack _ cover 2. cmm" is established after the normal operation of "stack _ cover 1. cmm" is finished. When the "STACK _ coverage 2. cmm" runs on the debugger, the STACK _ coverage 1.cmm "needs to be collected and stored on the hard disk of the testing computer in an offline mode to perform traversal analysis calculation by using the binary file import of the state, and the condition that the" config _ sim.t32 "file can be found under the corresponding path of the testing computer and the configuration information of the file is correct is required to be established on the basis that the" T32_ sim.
Furthermore, after the "STACK _ coverage 1. cm" script is run in the front to form a binary file under the "D: \ save" path, the script can be compiled to traverse the binary file without a debugger or by adopting other high-level languages to count the STACK utilization rate.
It should be noted that, for a technician, the technical staff needs to know the workflow of the mobile energy storage charging pile by applying the test scheme in the prior art, and how each ECU in the mobile energy storage charging pile works cooperatively; familiarity with HIL test equipment and debugger scripts is also required.
For the application, the most important thing for applying the test scheme of the present application is that technical personnel need to be familiar with the debugger script, and if the grammar of the debugger script is not familiar enough, the debugger script is difficult to be compiled to sample and analyze and count the STACK state of the program in the dynamic running process; in addition, because a test system needs to be built by adopting HIL test equipment to simulate the mobile energy storage charging pile to neutralize the charged electric automobile, other electronic control units need to be connected to the HIL by being familiar with the I/O interface definition of the HIL equipment to form a complete test system.
