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 an on-vehicle HMI device, as shown in fig. 1, where the method is used for detecting an on-vehicle HMI device, and the method mainly includes:
101. and receiving a detection instruction aiming at the vehicle-mounted N-connected-screen 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, the in-vehicle HMI (Human Machine Interface, human-machine interface) device serves as an important in-vehicle device, which is an important medium for interaction between a user and a vehicle. Currently, in order to enable the HMI device to provide better interaction experience for users, the on-board N-screen HMI device is also increasingly applied to vehicles. The vehicle-mounted N-screen HMI equipment comprises two or more screens, and each screen has different display functions. The vehicle-mounted 4-screen HMI equipment comprises an instrument screen, an air conditioner screen, an entertainment video screen and a secondary driving screen. In order to ensure the reliability of the vehicle-mounted HMI device, the vehicle-mounted HMI device needs to be detected in a development stage, a production stage and a offline stage of the vehicle-mounted HMI device.
Specifically, as the research and development stage, the production stage and the offline stage of the vehicle-mounted N-connected-screen HMI equipment are all required to be detected, three detection modes are set for the vehicle-mounted N-connected-screen HMI equipment aiming at the three stages, wherein 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 the vehicle-mounted N-screen HMI equipment in various test processes such as high and low temperature, vibration, electromagnetic compatibility and the like. The part offline detection mode is mainly used in the production offline detection stage of the vehicle-mounted N-connected screen HMI equipment, realizes offline detection of the vehicle-mounted N-connected screen HMI equipment, and eliminates defective products. The whole car off-line detection mode is mainly used for off-line detection of the whole car and detecting the vehicle-mounted N-connected screen HMI equipment on a whole car production assembly line.
Specifically, detection items for the vehicle-mounted N-linked-screen HMI device may be determined based on specific service requirements, and may include, but are not limited to, reading factory software and hardware version information, detecting a screen display effect, screen backlight, bluetooth communication, U-disc music reading, 2G/3G/4G/5G data transmission, 2G/3G/4G/5G call, WIFI data transmission, LIN communication, CAN communication, GPS positioning, vibration sensor detection, ethernet communication, optical sensor function, touch screen detection, standby battery discharge detection, apple IC authorization authentication, motherboard/central control/secondary drive temperature sensor detection, pot machine detection, peripheral voltage detection, RTC clock detection, USB inter-board communication, FM detection, head-to-eye camera detection, earphone interface, and MIC detection.
Specifically, one detection item may correspond to one or more detection modes, but since the detection requirements of different detection modes are different, the detection use cases of one detection item in different detection modes are different.
Specifically, when the vehicle-mounted N-connected screen HMI equipment needs to be detected, a detection personnel 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 setting interface; second, the target detection mode and the identification corresponding to the target detection item are input under the setting interface. It should be noted that, the target detection mode and the target detection item carried by the detection instruction can be flexibly combined based on the service requirement, so as to meet various detection requirements.
102. Selecting target detection equipment corresponding to the target detection item, and selecting a target detection case corresponding to the target detection item in the target detection mode.
In practical applications, the detection device is set according to the detection item. By way of example, 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, since the detection requirements of different detection items are different, different detection devices correspond to different detection items. For example, if the detection item is a 2G/3G/4G/5G call, the corresponding detection device is a speaker and a telephone. The detection item is GPS positioning, and the corresponding detection equipment is a GPS signal amplifier.
Specifically, when a detection instruction is received, selecting a target detection device corresponding to a target detection item carried by the detection instruction from preset detection devices based on the corresponding relation between the preset detection devices and the detection item, so as to execute detection related to the target detection item by using the selected target detection device.
In practical application, since the detection requirements of different detection modes are different, in order to meet the detection requirements of different modes, the detection cases of one detection item in different detection modes are different, that is, each detection item has a different detection case in different detection modes.
Specifically, when a detection instruction is received, a target detection case corresponding to the target detection item in the target detection mode is selected from preset detection cases based on the corresponding relation among the detection cases, the detection items and the detection modes, so that the detection of the correlation of the target detection item in the target detection mode is executed by using the selected target detection case.
103. And executing the target detection case by using the vehicle-mounted N-connected screen 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-connected screen HMI device and the target detection device, so that the vehicle-mounted N-connected screen HMI device and the target detection device cooperate to execute the target detection case.
Specifically, the process of executing the target detection case by matching the vehicle-mounted N-connected screen HMI device and the target detection device at least comprises the following two processes:
first, the on-board N-linked HMI device and the object detection device cooperate to execute an object detection use case once.
Secondly, the vehicle-mounted N-connected screen HMI equipment and the target detection equipment are utilized to execute the target detection use case in a preset period. The method can eliminate error detection caused by accidental occurrence due to the fact that multiple target detection cases are executed, so that the detection reliability is improved. Specifically, the detection result is obtained based on the detection information formed for each cycle. Illustratively, the detection result is obtained based on the average value of the detection information of each period.
Specifically, based on detection information formed by the target detection case executed by the vehicle-mounted N-connected screen HMI device and the target detection device, the process of obtaining a 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 executing the target detection case by the vehicle-mounted N-connected screen HMI equipment and the target detection equipment; and comparing the result parameter with the preset parameter to obtain the detection result. If the difference between the result parameter and the preset parameter is compared within the preset difference range, the fact that the vehicle-mounted N-screen HMI equipment has no problem is indicated, and a detection result passing the detection of the vehicle-mounted N-screen HMI equipment is generated. If the difference between the result parameter and the preset parameter is compared to be out of the preset difference range, the problem of the vehicle-mounted N-connected screen HMI equipment is indicated, a detection result that the vehicle-mounted N-connected screen HMI equipment fails to detect is generated, and an alarm is given based on the detection result that the vehicle-mounted N-connected screen HMI equipment fails to detect, so that a detector can timely conduct abnormality elimination processing on the vehicle-mounted N-connected screen HMI equipment according to the alarm.
According to the detection method of the vehicle-mounted HMI equipment, when the detection instruction aiming at the vehicle-mounted N-connected screen 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 using the vehicle-mounted N-connected screen HMI equipment and the target detection equipment to obtain a detection result. Therefore, in the embodiment of the disclosure, when the vehicle-mounted N-connected HMI device is detected, the detection device and the detection case can be used without manual verification. Therefore, the scheme provided by the embodiment of the disclosure can improve the automation degree of detection of the vehicle-mounted HMI equipment, greatly save manpower, and can meet long-term repeated detection, fully verify the reliability of the complex vehicle-mounted HMI equipment, thereby improving the quality of the factory-leaving vehicle-mounted HMI equipment.
In a second aspect, according to the method of the first aspect, another embodiment of the disclosure further provides a method for detecting an on-vehicle HMI device, as shown in fig. 2, where the method mainly includes:
201. when a detection instruction aiming at the vehicle-mounted N-connected screen HMI equipment is received, determining whether a last detection mode adjacent to the target detection mode exists or not based on the execution sequence of at least one preset detection mode; the detection instruction carries a target detection mode and a target detection item. If so, 202; otherwise, 203 is performed.
Specifically, the research and development stage, the production stage and the off-line stage of the vehicle-mounted N-connected-screen HMI equipment are all required to be detected, so three detection modes are set for the vehicle-mounted N-connected-screen HMI equipment aiming at the three stages, and the three detection modes comprise a design verification DV mode, a part off-line detection mode and a whole vehicle off-line detection mode. It can be seen that the different detection modes respectively correspond to the stages of the different vehicle-mounted N-linked-screen HMI devices, and the stages of the different vehicle-mounted N-linked-screen HMI devices have strict time sequence, so that the execution sequence is set for at least one preset detection mode based on the stages undergone by the vehicle-mounted N-linked-screen HMI devices. The detection time of the detection mode sequentially located at the rear cannot be earlier than the detection time of the detection mode sequentially located at the front. The detection sequence of the DV mode, the part offline detection mode and the whole vehicle offline detection mode is designed and checked as follows: the design verification DV mode is located before the part off-line detection mode, and the part off-line detection mode is located before the whole vehicle off-line detection mode.
Specifically, in order to ensure a strict detection sequence, when a detection instruction is received, it is required to determine whether a last detection mode adjacent to a target detection mode carried by the detection instruction exists based on an execution sequence of at least one preset detection mode. If it is detected that there is no previous detection pattern adjacent to the target detection pattern, indicating that the target detection pattern is the detection pattern ordered first, it is indicated that the detection can be performed, so 203 is performed. If a detection exists of a previous detection pattern adjacent to the target detection pattern, indicating that the target detection pattern is not the first-ordered detection pattern, then in order to determine if the current detection is executable, 202 is performed.
202. Judging whether the detection of the target detection item in a last detection mode adjacent to the target detection mode passes or not; if yes, execute 203; otherwise, execution 207 proceeds.
Specifically, when it is determined that the detection of the target detection item in the previous detection mode passes, it is indicated that the target detection item in the previous detection mode is acceptable, and the detection in the current detection mode is possible, so that 203 is executed.
Specifically, when it is determined that the detection of the target detection item in the previous detection mode is not passed, it is indicated that the target detection item in the previous detection mode is not qualified, in order to ensure the accuracy of the detection, the detection in the current detection mode cannot be performed, and after waiting for the target detection item in the previous detection mode to be qualified, the detection in the current detection mode is performed, so that the step 207 is performed.
203. And selecting target detection equipment corresponding to the target detection item.
Specifically, the detailed description of this step is substantially the same as that of step 102 described above, and thus 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 thus will not be repeated here.
205. And executing the target detection case by using the vehicle-mounted N-connected screen HMI equipment and the target detection equipment.
In practical application, in order to improve data processing and interaction efficiency of the vehicle-mounted N-connected-screen HMI device, the vehicle-mounted N-connected-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 HMI product. I.e., each card performs a different test case. The vehicle-mounted 4-screen HMI equipment comprises an instrument screen, an air conditioner screen, an entertainment video screen and a secondary driving screen, wherein the vehicle-mounted 4-screen HMI equipment comprises a first board card and a second board card, the first board card is used for controlling the entertainment video screen and the secondary driving screen, and the second board card is used for controlling the instrument screen and the air conditioner screen. That is, the first board card is used to execute a detection case related to the in-vehicle center control system, and the second board card is used to execute a detection case related to the driver instrument system.
Specifically, because different boards in the vehicle-mounted N-linked-screen HMI device execute different detection cases, the process of executing the target detection cases by using the vehicle-mounted N-linked-screen HMI device and the target detection device respectively may include: determining a target board card for executing the target detection case in M board cards of the vehicle-mounted N-connected-screen 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 use case by using the target detection equipment.
Specifically, since the CAN (Controller Area Network ) bus in the vehicle is responsible for data transmission of various vehicle-mounted devices, when the target board card is used to execute the target detection case, a start detection instruction for the target detection case CAN be sent to the target board card through the CAN bus, so that the target board card executes the target detection case in cooperation with the target detection device based on the start detection instruction. When the target board card executes the target detection use case, 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 and reduce the load of the board, one board may include a first processing chip and a second processing chip. The second processing chip is used for acquiring data, such as acquiring the electric quantity of a vehicle-mounted battery and collecting audio through MIC. The first processing chip is used for processing data, for example, judging whether the vehicle is charged or not based on the vehicle-mounted battery electric quantity acquired by the second processing chip. Specifically, the first processing chip is used for triggering the second processing chip under the triggering of the detection equipment; 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 use case under the triggering 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 using the vehicle-mounted N-screen HMI equipment and the target detection equipment to obtain a detection result.
Specifically, the detecting information formed by the target detection case is executed by using the vehicle-mounted N-connected screen HMI device and the target detection device, so as to obtain a detection result, including: extracting preset parameters from the target detection case, and extracting result parameters corresponding to the preset parameters from detection information formed by executing the target detection case by the vehicle-mounted N-connected screen HMI equipment and the target detection equipment; 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 executing the target detection case by the vehicle-mounted N-connected-screen HMI device and the target detection device at least includes two processes:
firstly, when the vehicle-mounted N-connected screen HMI equipment and the target detection equipment are matched to execute the target detection case once, the result parameters are directly extracted from the detection information of the time.
Secondly, when the vehicle-mounted N-connected screen HMI equipment and the target detection equipment are utilized in a preset period to execute the target detection case, respectively extracting result parameters from the detection information of each period, carrying out average processing on the extracted result parameters, and obtaining the result parameters after the average processing.
Thirdly, when the target detection case is executed by using the vehicle-mounted N-connected screen HMI device and the target detection device in a preset period, the result parameters are respectively extracted from the detection information of each period. In order to eliminate the influence of accidental factors, the highest and lowest result parameters can be removed first, then the average processing is carried out on the remaining result parameters, and the first result parameters are obtained after the average processing.
It should be noted that the specific types of the result parameters and the preset parameters are related to the executed detection cases. For example, when the detection case is "a section of audio" of the 4G communication detection case, the result parameter and the preset parameter are both the frequency and the waveform of the audio. When the detection case is a front-view camera detection case of 'one picture', the result parameter and the preset parameter are both the resolution and the pixels of the picture.
Specifically, the process 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 the preset parameter, and determining whether the comparison result is within a preset difference range. If the difference between the result parameter and the preset parameter is compared within a preset difference range, the detection passing of the target detection item of the vehicle-mounted N-connected screen HMI equipment in the target detection mode is indicated, and a detection result of the detection passing of the vehicle-mounted N-connected screen HMI equipment is generated. If the difference between the result parameter and the preset parameter is compared to be out of the preset difference range, the fact that the detection of the target detection item of the vehicle-mounted N-connected screen HMI equipment in the target detection mode fails is indicated, a detection result of the vehicle-mounted N-connected screen HMI equipment failing to pass the detection is generated, and an alarm is given based on the detection result failing to pass the detection, so that service personnel can carry out abnormal processing on the detection of the vehicle-mounted N-connected screen HMI equipment according to the alarm.
