Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In a first aspect, an embodiment of the present disclosure provides a method for detecting a vehicle-mounted HMI device, as shown in fig. 1, the method is used for detecting the vehicle-mounted HMI device, and the method mainly includes:
101. receiving a detection instruction aiming at the vehicle-mounted N screen connection HMI equipment, wherein the detection instruction carries a target detection mode and a target detection item, and N is an integer greater than or equal to 2.
In practical applications, a Human Machine Interface (HMI) device is an important vehicle-mounted device, and is an important medium for interaction between a user and a vehicle. At present, in order to enable the HMI device to provide better interactive experience for users, the vehicle-mounted N-screen HMI device is also increasingly applied to vehicles. The vehicle-mounted N-screen HMI device comprises two or more screens, and each screen has different display functions. Illustratively, the vehicle-mounted 4-screen HMI device comprises an instrument screen, an air conditioner screen, an entertainment audio screen and a secondary driving screen. In order to ensure the reliability of the vehicle-mounted HMI equipment, the vehicle-mounted HMI equipment needs to be detected in the research and development stage, the production stage and the offline stage of the vehicle-mounted HMI equipment.
Specifically, the vehicle-mounted N-screen HMI equipment needs to be detected in a research and development stage, a production stage and a offline stage, so three detection modes are set for the vehicle-mounted N-screen HMI equipment in the three stages, and the three detection modes comprise a design verification DV mode, a part offline detection mode and a whole vehicle offline detection mode. The DV mode is mainly used for detecting vehicle-mounted N-screen HMI equipment in various test processes of high and low temperature, vibration, electromagnetic compatibility and the like. The component offline detection mode is mainly used for the production offline detection stage of the vehicle-mounted N screen-connected HMI equipment, offline detection of the vehicle-mounted N screen-connected HMI equipment is achieved, and defective products are eliminated. The whole vehicle offline detection mode is mainly used for offline detection of a whole vehicle and detection of vehicle-mounted N screen connection HMI equipment on a whole vehicle production assembly line.
Specifically, the detection items aiming at the vehicle-mounted N screen-connected HMI device can be determined based on specific service requirements, and may include, but is not limited to, reading factory software and hardware version information, detecting screen display effect, screen backlight, bluetooth communication, USB disk music reading, 2G/3G/4G/5G data transmission, 2G/3G/4G/5G talk, WIFI data transmission, LIN communication, CAN communication, GPS positioning, vibration sensor detection, ethernet communication, light sensor function, touch screen detection, backup battery discharge detection, apple inc authorization authentication, motherboard/center control/rider temperature sensor detection, pot detection, peripheral voltage detection, RTC clock detection, USB inter-board communication, FM detection, around-view camera and front-view camera detection, headphone interface, and MIC detection.
Specifically, one detection item may correspond to one or more detection modes, but different detection modes have different detection requirements, so that the detection cases of one detection item in different detection modes are different.
Specifically, when the vehicle-mounted N-screen HMI equipment needs to be detected, a detection person can issue a detection instruction in at least the following two modes: firstly, triggering a target detection mode and a button corresponding to a target detection item under a set interface; and secondly, inputting a target detection mode and a mark corresponding to a target detection item under a setting interface. It should be noted that the target detection mode and the target detection item carried by the detection instruction may be flexibly combined based on the service requirement, thereby satisfying various detection requirements.
102. And selecting target detection equipment corresponding to the target detection items, and selecting target detection cases corresponding to the target detection items in the target detection mode.
In practical applications, the detection device is set according to the detection items. Illustratively, the detection device may include, but is not limited to, at least one of a speaker, a GPS signal amplifier, a telephone, and an FM signal generator. It should be noted that, because the detection requirements of different detection items are different, different detection devices correspond to different detection items. Illustratively, if the detection item is a 2G/3G/4G/5G call, the corresponding detection devices are a sound box and a telephone. And if the detection item is GPS positioning, the corresponding detection equipment is a GPS signal amplifier.
Specifically, when the detection instruction is received, based on a preset corresponding relationship between the detection device and the detection item, the target detection device corresponding to the target detection item carried by the detection instruction is selected from the preset detection devices, so that the selected target detection device is used to perform the detection related to the target detection item.
In practical applications, different detection modes have different detection requirements, so that in order to meet the detection requirements in different modes, one detection item has different detection cases in different detection modes, that is, each detection item has different detection cases in different detection modes.
Specifically, when a detection instruction is received, based on the corresponding relationship among the detection use cases, the detection items, and the detection modes, the target detection use case corresponding to the target detection item in the target detection mode is selected from the preset detection use cases, so that the selected target detection use case is used to perform the related detection of the target detection item in the target detection mode.
103. And executing the target detection case by utilizing the vehicle-mounted N screen connection HMI equipment and the target detection equipment to obtain a detection result.
Specifically, when the target detection case is selected, the target detection case is respectively issued to the vehicle-mounted N-screen connection HMI device and the target detection device, so that the vehicle-mounted N-screen connection HMI device and the target detection device are matched to execute the target detection case.
Specifically, the process of executing the target detection case by matching the vehicle-mounted N screen connection HMI equipment and the target detection equipment at least comprises the following two steps:
firstly, the vehicle-mounted N screen connection HMI equipment and the target detection equipment are matched to execute a target detection case once.
And secondly, executing the target detection case by utilizing the vehicle-mounted N screen connection HMI equipment and the target detection equipment in a preset period. The method can eliminate accidental false detection due to multiple target detection cases, thereby improving the detection reliability. Specifically, the detection result is obtained based on the detection information formed every cycle. Illustratively, the detection result is obtained based on an average value of the detection information of each period.
Specifically, based on the vehicle-mounted N-screen HMI device and the target detection device executing the detection information formed by the target detection case, the process of obtaining the detection result is as follows: extracting preset parameters from the target detection case, and extracting result parameters corresponding to the preset parameters from detection information formed by the vehicle-mounted N-screen connection HMI equipment and the target detection equipment executing the target detection case; and comparing the result parameters with the preset parameters to obtain the detection result. And if the difference between the result parameter and the preset parameter is in a preset difference range, the fact that the vehicle-mounted N-screen connection HMI equipment has no problem is indicated, and a detection result that the vehicle-mounted N-screen connection HMI equipment passes detection is generated. If the difference between the result parameter and the preset parameter is out of the preset difference range, the fact that the vehicle-mounted N screen connection HMI equipment has problems is indicated, a detection result that the vehicle-mounted N screen connection HMI equipment fails in detection is generated, and an alarm is given based on the detection result that the detection result fails, so that a detector can timely carry out exception elimination processing on the vehicle-mounted N screen connection HMI equipment according to the alarm.
According to the detection method of the vehicle-mounted HMI equipment, when a detection instruction aiming at the vehicle-mounted N screen connection HMI equipment is received, the target equipment corresponding to the target detection item carried by the detection instruction is selected, and the target detection case corresponding to the target detection item in the target detection mode carried by the detection instruction is selected. And then, executing the target detection case by utilizing the vehicle-mounted N screen connection HMI equipment and the target detection equipment to obtain a detection result. Therefore, when the vehicle-mounted N-screen HMI equipment is detected, the detection can be completed through the detection equipment and the detection case, and manual verification is not needed. Therefore, the scheme provided by the embodiment of the disclosure can improve the automation degree of detection of the vehicle-mounted HMI equipment, greatly saves labor, can meet long-term repeated detection, and fully verifies the reliability of the complex vehicle-mounted HMI equipment, thereby improving the quality of the factory vehicle-mounted HMI equipment.
In a second aspect, according to the method in the first aspect, another embodiment of the present disclosure further provides a method for detecting a vehicle HMI device, as shown in fig. 2, the method mainly includes:
201. when a detection instruction aiming at the vehicle-mounted N-screen connection HMI equipment is received, determining whether a last detection mode adjacent to the target detection mode exists or not based on a preset execution sequence of at least one detection mode; the detection instruction carries a target detection mode and a target detection item. If so, execute 202; otherwise, 203 is executed.
Specifically, the vehicle-mounted N-screen HMI equipment needs to be detected in a research and development stage, a production stage and a offline stage, so that three detection modes are set for the vehicle-mounted N-screen HMI equipment in the three stages, and the three detection modes comprise a design verification DV mode, a part offline detection mode and a whole vehicle offline detection mode. Therefore, different detection modes respectively correspond to different phases of the vehicle-mounted N-screen HMI equipment, and the phases of the different vehicle-mounted N-screen HMI equipment have strict time sequences, so that an execution sequence is set for at least one preset detection mode based on the phases of the vehicle-mounted N-screen HMI equipment. It should be noted that the detection time of the detection mode sequentially positioned at the back cannot be earlier than the detection time of the detection mode sequentially positioned at the front. The detection sequence of the design verification DV mode, the component offline detection mode and the whole vehicle offline detection mode is as follows: the design verification DV mode is located before the part offline detection mode, and the part offline detection mode is located before the whole vehicle offline detection mode.
Specifically, in order to ensure a strict detection sequence, when a detection instruction is received, it is determined whether a previous detection mode adjacent to a target detection mode carried by the detection instruction exists based on a preset execution sequence of at least one detection mode. If there is no last detection pattern adjacent to the target detection pattern, indicating that the target detection pattern is the detection pattern ordered at the first position, it indicates that the detection can be performed, so 203 is performed. If there is a last detection pattern adjacent to the target detection pattern, indicating that the target detection pattern is not the first-ranked detection pattern, 202 is performed to determine whether the current detection is executable.
202. Judging whether the detection of the target detection item in the last detection mode adjacent to the target detection mode passes or not; if so, go to 203; otherwise, 207 is performed.
Specifically, when it is determined that the target detection item passes the detection in the previous detection mode, it indicates that the target detection item is qualified in the previous detection mode, and the detection in the current detection mode can be performed, so 203 is performed.
Specifically, when it is determined that the target detection item fails to be detected in the previous detection mode, it indicates that the target detection item is not qualified in the previous detection mode, and in order to ensure the detection accuracy, the detection in the current detection mode cannot be performed, and it is necessary to wait for the target detection item to be qualified in the previous detection mode, and then the detection in the current detection mode may be performed, so 207 is performed.
203. And selecting target detection equipment corresponding to the target detection items.
Specifically, the detailed description of this step is substantially the same as that of step 102 described above, and therefore, the detailed description thereof will not be repeated here.
204. And selecting a target detection case corresponding to the target detection item in the target detection mode.
Specifically, the detailed description of this step is substantially the same as that of step 102 described above, and therefore, the detailed description thereof will not be repeated here.
205. And executing the target detection case by utilizing the vehicle-mounted N screen connection HMI equipment and the target detection equipment.
In practical application, in order to improve data processing and interaction efficiency of the vehicle-mounted N-screen HMI device, the vehicle-mounted N-screen HMI device includes M boards, where M is an integer greater than or equal to 1. Each board card is used for controlling at least one screen of the vehicle-mounted N screen-connected HMI product. That is, each board executes a different test case. Illustratively, the vehicle-mounted 4 screen-connected HMI device comprises an instrument screen, an air conditioner screen, an entertainment audio-visual screen and an auxiliary driving screen, and the vehicle-mounted 4 screen-connected HMI device comprises a first board card and a second board card, wherein the first board card is used for controlling the entertainment audio-visual screen and the auxiliary driving screen, and the second board card is used for controlling the instrument screen and the air conditioner screen. That is, the first board is used for executing a test case related to the vehicle-mounted central control system, and the second board is used for executing a test case related to the driver instrument system.
Specifically, because different board cards in the vehicle-mounted N-screen HMI device execute different detection cases, the process of respectively executing the target detection case by using the vehicle-mounted N-screen HMI device and the target detection device may include: determining a target board card for executing the target detection case from M board cards of the vehicle-mounted N screen-connected HMI equipment; each board card is used for controlling at least one screen of the vehicle-mounted N-screen HMI product; executing the target detection case by using the target board card; and executing the target detection case by using the target detection equipment.
Specifically, because a Controller Area Network (CAN) bus in the vehicle is responsible for data transmission of various vehicle-mounted devices, when a target board card is used to execute a target detection case, a start detection instruction for the target detection case may be sent to the target board card through the CAN bus, so that the target board card cooperates with the target detection device to execute the target detection case based on the start detection instruction. When the target board card completes the target detection case, the detection information CAN be fed back through the CAN bus.
In addition, in practical application, in order to increase the data processing speed of the board card and reduce the load of the board card, one board card may include a first processing chip and a second processing chip. The second processing chip is used for acquiring data, for example, acquiring the electric quantity of a vehicle-mounted battery, and collecting audio by an MIC. The first processing chip is used for processing data, for example, judging whether the vehicle is charged or not based on the electric quantity of the vehicle-mounted battery acquired by the second processing chip. Specifically, the first processing chip is configured to trigger the second processing chip under the trigger of the detection device; executing the target detection case according to the data which is fed back by the second processing chip and is related to the target detection case; and the second processing chip is used for collecting data related to the target detection case under the trigger of the first processing chip and feeding the data back to the first processing chip.
206. And executing detection information formed by the target detection case by utilizing the vehicle-mounted N screen connection HMI equipment and the target detection equipment to obtain a detection result.
Specifically, executing detection information formed by the target detection case by using the vehicle-mounted N-screen HMI device and the target detection device to obtain a detection result includes: extracting preset parameters from the target detection case, and extracting result parameters corresponding to the preset parameters from detection information formed by the vehicle-mounted N-screen connection HMI equipment and the target detection equipment executing the target detection case; comparing the result parameter with the preset parameter to obtain the detection result
Specifically, the process of extracting the result parameter corresponding to the preset parameter from the detection information formed by the vehicle-mounted N screen connection HMI device and the target detection device executing the target detection case includes at least two types:
firstly, when the vehicle-mounted N-screen connection HMI equipment and the target detection equipment are matched to execute a target detection case once, the result parameters are directly extracted from the detection information of the time.
Secondly, when the target detection case is executed by utilizing the vehicle-mounted N screen connection HMI equipment and the target detection equipment in a preset period, result parameters are respectively extracted from detection information of each period, the extracted result parameters are subjected to average processing, and the result parameters are obtained after the average processing.
Thirdly, when the vehicle-mounted N-screen connection HMI equipment and the target detection equipment are used for executing the target detection case in a preset period, result parameters are respectively extracted from detection information of each period. In order to eliminate the influence of accidental factors, the highest and lowest result parameters can be removed, and then the remaining result parameters are averaged, and the average result parameter is the first result parameter.
It should be noted that the specific types of result parameters and preset parameters are related to the executed detection cases. Illustratively, when the detection use case is 4G communication detection use case "a segment of audio", the resulting parameter and the preset parameter are both the frequency and waveform of the audio. When the detection case is a forward-looking camera detection case of one picture, the result parameters and the preset parameters are the resolution and the pixels of the picture.
Specifically, the step of comparing the result parameter with the preset parameter to obtain the detection result may include: and determining a comparison result of the result parameter and a preset parameter, and determining whether the comparison result is within a preset difference range. And if the difference between the result parameter and the preset parameter is in a preset difference range, the fact that the target detection item of the vehicle-mounted N-screen connection HMI equipment passes the detection in the target detection mode is indicated, and then a detection result that the vehicle-mounted N-screen connection HMI equipment passes the detection is generated. If the difference between the result parameter and the preset parameter is out of the preset difference range through comparison, the fact that the detection of the target detection item of the vehicle-mounted N screen connection HMI equipment in the target detection mode is failed is indicated, a detection result that the detection of the vehicle-mounted N screen connection HMI equipment is failed is generated, and based on the detection result that the detection is failed, an alarm is given, so that service personnel can carry out exception handling on the detection of the vehicle-mounted N screen connection HMI equipment according to the alarm.
207. And sending a prompt for detecting the instruction violation.
Specifically, the prompt can be displayed to the detection personnel on a set interface, so that the detection personnel can adjust the detection progress in time based on the prompt.
According to the method shown in fig. 1 or fig. 2, a detection method of a vehicle-mounted HMI device is further provided according to another embodiment of the present disclosure, taking the vehicle-mounted HMI device with 4 screens, the target detection mode being the "part offline detection mode", and the target detection item being the "4G communication", as shown in fig. 3, the method includes:
301. when a detection instruction for the vehicle-mounted 4 screen-connected HMI equipment is received, the design verification DV mode adjacent to the last detection mode of the target detection mode 'component offline detection mode' is determined to exist based on the execution sequence of the preset design verification DV mode, the component offline detection mode and the whole vehicle offline detection mode, and the execution is carried out 302.
