The detection method before the offline of the VTCU controller provided by the embodiment of the invention is executed by the computer equipment, and correspondingly, the detection system before the offline of the VTCU controller runs in the computer equipment. The order of the steps in the flow chart may be changed and some may be omitted according to different needs.
As shown in fig. 3, the method includes the following steps.
S1, a function detection program is written into the VTCU controller.
It should be noted that, the detection tool controller is pre-written with a related detection program, and after the VTCU controller to be detected is connected with the detection tool controller, the VTCU controller is only required to be written with a function detection program. After the current VTCU controller is detected, the current VTCU controller is pulled out from the detection station, and then the next VTCU controller to be detected is installed for detection.
S2, the detection function detects whether program writing is successful.
In this embodiment, after the function detection program is written into the VTCU controller, the refresh progress of the function detection program is monitored in real time, and the refresh progress of the function detection program is displayed on the man-machine interaction interface, so that the inspector can intuitively and timely view the writing progress on the interface. It should be noted that the result of the brushing is also displayed on the interface, and the next step is prompted after the brushing is successful.
And S3, if the controller is unsuccessful, judging that the VTCU controller is not qualified.
And S4, if the detection is successful, sending a detection execution command to the VTCU controller and the detection tool controller, and triggering the VTCU controller and the detection tool controller to interact according to a function detection program so as to execute the function detection of the VTCU controller.
After receiving the detection execution command, the VTCU controller and the detection tool controller start to execute the function detection program, and perform corresponding interaction according to the detection flow specified by the function detection program, so as to sequentially detect each function of the VTCU controller.
S5, receiving a detection signal of the VTCU controller for executing function detection.
The upper computer and the VTCU controller are communicated through the CAN bus, if the CAN bus of the VTCU controller CAN normally communicate, the correct detection signal CAN be received, otherwise, the detection signal CAN not be received or the received detection signal is abnormal. Based on the above, after sending a detection execution command to the VTCU controller and the detection tool controller, the embodiment first determines whether a detection signal for detecting the function executed by the VTCU controller is received within a preset time period; if not, judging that the CAN bus of the VTCU controller is abnormal in function, and judging that the VTCU controller is unqualified; if yes, judging whether the attribute of the received detection signal is normal, including whether the type of the detection signal is normal and whether the quantity of the detection signal is normal; if not, judging that the CAN bus of the VTCU controller is abnormal in function, and judging that the VTCU controller is unqualified; if so, judging that the CAN bus of the VTCU controller is normal in function, and executing the next step to judge whether each relevant function of the VTCU controller is normal according to the detection signal. The detection of the CAN bus function of the VTCU controller is realized through the steps.
And S6, judging whether each relevant function of the VTCU controller is normal or not according to the detection signals.
In this embodiment, the detection signals include a KEY (key_on) signal, a wake-up (AWAKE) signal, a high-side function detection signal, a low-side function detection signal, a PWM acquisition signal, a high-efficiency signal, a low-efficiency signal, a 5V power output, an analog acquisition signal, a position sensor detection signal, an input shaft sensor detection signal, an output shaft sensor detection signal, an EEPROM self-test signal, and an IMU inertial unit self-test signal.
And comparing each detection signal with the state of the relevant expected signal, and judging whether each relevant function of the VTCU controller is normal or not according to the comparison result. If the detected signal is the same as the relevant expected signal, the relevant function is normal, otherwise, the relevant function is abnormal.
And S7, if all relevant functions of the VTCU controller are normal, judging that the VTCU controller is qualified.
And S8, if any relevant function of the VTCU controller is abnormal, judging that the VTCU controller is unqualified.
In order to improve factory efficiency of the VTCU controller, when all relevant functions of the VTCU controller are normal after detection of all relevant functions of the VTCU controller are finished, the boot brushing of the boot program is automatically finished at the current station. Specifically, after each relevant function of the VTCU controller is normal, the boot program is written into the VTCU controller, whether the boot program is written successfully or not is detected, if so, the VTCU controller is judged to be qualified, if not, the VTCU controller is judged to be unqualified, and meanwhile, the detection of the boot writing function of the VTCU controller is realized.
After the boot program is written into the VTCU controller, the refreshing progress of the boot program is monitored, the refreshing progress of the boot program is displayed on a human-computer interaction interface, so that a inspector can know the writing progress in time, and meanwhile, the writing result is displayed on the interface.
In one embodiment, a 24V direct current power supply, a VTCU controller, a detection tool controller and a CAN acquisition card are connected together through a test harness, and then the CAN acquisition card is connected with an upper computer (with an installed off-line detection software) to form a detection framework for a VTCU controller production line. Clicking a 'test program flashing' button in the offline detection software to start flashing a test program in the VTCU controller, if the detection software prompts that the flashing fails, the VTCU controller is unqualified, if the detection software prompts that the flashing succeeds, clicking the 'offline detection' button in the offline detection software to start the offline function test of hardware of the VTCU controller, if the detection software prompts that the function is abnormal, the VTCU controller is unqualified, if the detection software prompts that the function is normal, clicking a 'BOOT flashing' button in the offline detection software to start flashing a BOOT program in the VTCU controller, if the detection software prompts that the flashing fails, the VTCU controller is unqualified, if the detection software prompts that the flashing succeeds, the VTCU controller is qualified, and the detection process is ended, and the VTCU controller meets the offline requirement.
