技术领域Technical Field
本发明涉及车辆技术领域，具体地涉及指示图标的校验方法、计算机存储介质和车辆。The present invention relates to the technical field of vehicles, and in particular to a verification method for an indication icon, a computer storage medium and a vehicle.
背景技术Background technique
汽车仪表盘是驾驶员获取车辆信息的重要载体，而其中的指示图标(即WarningTelltale Indicator)则是用来提供车辆状态和故障信息的。根据作用的不同，可以将指示图标大致分为日常指示图标、警示指示图标和故障指示图标。其中，日常指示图标主要用于提示车辆各功能的开关情况，例如车门是否关闭、车灯是否开启等；警示指示图标主要作用是告知驾驶员车辆的状况，例如电池和各油液(例如机油、刹车油等)储量；故障指示图标主要用于提示车辆的故障部位，以帮助驾驶员及时发现并处理故障，避免造成损失或危险。The car dashboard is an important carrier for drivers to obtain vehicle information, and the indicator icons (i.e. Warning Telltale Indicator) are used to provide vehicle status and fault information. According to their different functions, indicator icons can be roughly divided into daily indicator icons, warning indicator icons and fault indicator icons. Among them, daily indicator icons are mainly used to indicate the switch status of various functions of the vehicle, such as whether the doors are closed, whether the lights are turned on, etc.; the main function of warning indicator icons is to inform the driver of the vehicle's condition, such as the battery and various oil (such as engine oil, brake oil, etc.) reserves; fault indicator icons are mainly used to indicate the faulty parts of the vehicle to help the driver find and deal with the fault in time to avoid losses or dangers.
指示图标的工作原理通常是通过与车辆的各系统相连的传感器或开关来检测车辆的状态或故障，电子控制单元(即Electronic Control Unit)获取到相应的信号后将图标的请求显示信号传输给座舱控制器(即Cockpit Controller)，座舱控制器根据请求显示信号在汽车仪表盘上显示对应的指示图标。The working principle of the indicator icon is usually to detect the status or fault of the vehicle through sensors or switches connected to various systems of the vehicle. After the electronic control unit (i.e., Electronic Control Unit) obtains the corresponding signal, it transmits the icon request display signal to the cockpit controller (i.e., Cockpit Controller). The cockpit controller displays the corresponding indicator icon on the car dashboard according to the request display signal.
指示图标对整车安全至关重要。然而，由于传感器故障、线路问题、仪表盘故障、软件故障和外部干扰等诸多因素的影响，导致实际使用过程中指示图标在汽车仪表盘上可能无法正常显示。这不仅极大地影响了用户的使用体验，而且存在较大的安全隐患，容易诱发行车事故。Indicator icons are crucial to vehicle safety. However, due to many factors such as sensor failure, line problems, dashboard failure, software failure and external interference, indicator icons may not be displayed properly on the car dashboard during actual use. This not only greatly affects the user experience, but also poses a major safety hazard and easily induces traffic accidents.
因此，本领域需要一种新的技术方案来解决上述问题。Therefore, this field needs a new technical solution to solve the above problems.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that in the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
为了解决或者在一定程度上改善现有技术中无法有效判定汽车仪表盘的指示图标是否正常显示的技术问题，本发明提供一种指示图标100的校验方法。该校验方法包括：将指示图标100划分成多个图像块(步骤S1)；获取每个图像块的图像信息(步骤S2)；将图像信息与预设图像信息进行比较(步骤S3)；和基于比较结果判断指示图标100是否显示正常(步骤S4)。In order to solve or improve to a certain extent the technical problem in the prior art that it is not possible to effectively determine whether the indicator icon of the car dashboard is displayed normally, the present invention provides a verification method for the indicator icon 100. The verification method includes: dividing the indicator icon 100 into multiple image blocks (step S1); obtaining image information of each image block (step S2); comparing the image information with preset image information (step S3); and judging whether the indicator icon 100 is displayed normally based on the comparison result (step S4).
图1是本发明指示图标的校验方法的流程示意图。如图1所示，在一种或多种实施例中，当本发明指示图标100的校验方法开始后，首先执行步骤S1，即将指示图标100划分成多个图像块。接着，校验方法前进到步骤S2，即获取每个图像块的图像信息。然后，将图像信息与预设图像信息进行比较(即步骤S3)。最后，校验方法执行步骤S4，即基于比较结果判断指示图标100是否显示正常。通过上述的设置，本发明指示图标100的校验方法能够精准且自动地判断出指示图标100是否显示正常，提高指示图标100显示的准确性，防止指示图标100显示异常带来的行车风险，从而提高整车的安全性。FIG1 is a flow chart of the verification method of the indicator icon of the present invention. As shown in FIG1, in one or more embodiments, when the verification method of the indicator icon 100 of the present invention is started, step S1 is first executed, that is, the indicator icon 100 is divided into a plurality of image blocks. Next, the verification method proceeds to step S2, that is, obtaining the image information of each image block. Then, the image information is compared with the preset image information (i.e., step S3). Finally, the verification method executes step S4, that is, judging whether the indicator icon 100 is displayed normally based on the comparison result. Through the above-mentioned settings, the verification method of the indicator icon 100 of the present invention can accurately and automatically judge whether the indicator icon 100 is displayed normally, improve the accuracy of the display of the indicator icon 100, and prevent the driving risks caused by the abnormal display of the indicator icon 100, thereby improving the safety of the entire vehicle.
图2是本发明指示图标的校验方法的第一实施例的流程示意图。如图2所示，在一种或多种实施例中，本发明指示图标100的校验方法开始后，首先执行步骤S10，即将指示图标100划分成多个图像块。图6是本发明指示图标100的校验方法中划分图像块的实施例的示意图。如图6所示，在一种或多种实施例中，该指示图标100为电频故障指示图标100。替代地，指示图标100为机油报警指示图标100、发动机报警指示图标100、水温报警指示图标100、刹车故障指示图标100、胎压报警指示图标100、制动系统警告指示图标100或者其它合适的指示图标100。指示图标100的颜色可以是红色、黄色或者其它合适的颜色，只要符合国家标准GB 4094-2016《汽车操作件、指示器及信号装置的标志》即可。在一种或多种实施例中，将指示图标100划分成10个图像块，分别是第一图像块101、第二图像块102、第三图像块103、第四图像块104、第五图像块105、第六图像块106、第七图像块107、第八图像块108、第九图像块109和第十图像块110。替代地，图像块的数量也设置成比10个多或少的其它合适的数量，例如9个、11个等。另外，每个图像块的大小也可根据指示图标100的具体形状进行调整。FIG. 2 is a flow chart of a first embodiment of a verification method for an indicator icon of the present invention. As shown in FIG. 2, in one or more embodiments, after the verification method for the indicator icon 100 of the present invention is started, step S10 is first performed, that is, the indicator icon 100 is divided into a plurality of image blocks. FIG. 6 is a schematic diagram of an embodiment of dividing image blocks in the verification method for the indicator icon 100 of the present invention. As shown in FIG. 6, in one or more embodiments, the indicator icon 100 is an electric frequency fault indicator icon 100. Alternatively, the indicator icon 100 is an oil alarm indicator icon 100, an engine alarm indicator icon 100, a water temperature alarm indicator icon 100, a brake fault indicator icon 100, a tire pressure alarm indicator icon 100, a brake system warning indicator icon 100 or other suitable indicator icons 100. The color of the indicator icon 100 can be red, yellow or other suitable colors, as long as it complies with the national standard GB 4094-2016 "Signs of Automobile Operating Parts, Indicators and Signal Devices". In one or more embodiments, the indication icon 100 is divided into 10 image blocks, namely, a first image block 101, a second image block 102, a third image block 103, a fourth image block 104, a fifth image block 105, a sixth image block 106, a seventh image block 107, an eighth image block 108, a ninth image block 109 and a tenth image block 110. Alternatively, the number of image blocks is also set to other suitable numbers more or less than 10, such as 9, 11, etc. In addition, the size of each image block can also be adjusted according to the specific shape of the indication icon 100.
如图2所示，当步骤S10完成后，本发明指示图标100的校验方法前进到步骤S20，即获取每个图像块的图像信息。接着，校验方法执行步骤S30，判断每个图像块的图像信息是否均与预设图像信息相同。在一种或多种实施例中，图像块的图像信息为RGB均值。相应地，预设图像信息为预设的RGB均值。需要指出的是，指示图标100大多采用单色显示，因此通过获取图像块的RGB均值即可方便且精准地获取其显示情况。例如，红色的RGB值为(255，0，0)，其RGB均值为85.0；黄色的RGB值为(255，255，0)，其RGB均值为173.33。当判断结果为是时，即每个图像块的RGB均值均等于预设的RGB均值，则判定指示图标100显示正常(即步骤S41)。否则，则判定指示图标100显示不正常(即步骤S42)。通过上述的设置，可以简化控制逻辑，确保判定结果的准确性。替代地，图像块的图像信息也可设置成修正后的RGB均值，以降低数据波动对判定结果造成的不利影响。As shown in FIG. 2 , after step S10 is completed, the verification method of the indicator icon 100 of the present invention proceeds to step S20, that is, obtaining the image information of each image block. Then, the verification method executes step S30 to determine whether the image information of each image block is the same as the preset image information. In one or more embodiments, the image information of the image block is the RGB mean. Accordingly, the preset image information is the preset RGB mean. It should be noted that the indicator icon 100 is mostly displayed in monochrome, so its display condition can be conveniently and accurately obtained by obtaining the RGB mean of the image block. For example, the RGB value of red is (255, 0, 0), and its RGB mean is 85.0; the RGB value of yellow is (255, 255, 0), and its RGB mean is 173.33. When the judgment result is yes, that is, the RGB mean of each image block is equal to the preset RGB mean, then it is determined that the indicator icon 100 is displayed normally (i.e., step S41). Otherwise, it is determined that the indicator icon 100 is displayed abnormally (i.e., step S42). Through the above settings, the control logic can be simplified to ensure the accuracy of the judgment result. Alternatively, the image information of the image block may also be set to a modified RGB mean value to reduce the adverse effect of data fluctuation on the determination result.
图3是本发明指示图标的校验方法的第二实施例的流程示意图。如图3所示，在一种或多种实施例中，当指示图标100显示正常时，本发明校验方法前进到步骤S51，即获取指示图标100的请求显示时间和实际显示时间。其中，“请求显示时间”和“实际显示时间”可以通过车辆内部的传感器和计时系统获得。例如，当电子控制单元(即ECU)根据传感器检测到的信号并发出相应的图标显示请求时，计时系统记录一个时间戳。该时间戳所记录的时间即为“请求显示时间”，它可以由微处理器或计时器生成。在一种或多种实施例中，以本发明在执行步骤S30后判定指示图标100显示正常的时间点作为指示图标100的“实际显示时间”。替代地，实际显示时间也可选取其它合适的时间点。接着，校验方法执行步骤S52，即判断实际显示时间与请求显示时间之间的差值是否小于等于预设时间差值。在一种或多种实施例中，预设时间差值的范围为500ms(即毫秒)-800ms，例如500ms、600ms、700ms、800ms等，使得预设时间差值具有适中的数值，以确保判断结果的精度。替代地，预设时间差值也可设置成其它合适的时间值。基于比较结果判定指示图标100是否显示延时。具体而言，当判断结果为是时，校验方法前进到步骤S53，即判定指示图标100没有显示延时。否则，校验方法前进到步骤S54，即判定指示图标100显示延时。当判定指示图标100显示延时后，可以通过合适的方式(例如文本显示、语音提醒等)向用户发出提醒，以便用户及时维修，消除行车隐患。FIG3 is a flow chart of a second embodiment of the verification method of the indicator icon of the present invention. As shown in FIG3, in one or more embodiments, when the indicator icon 100 is displayed normally, the verification method of the present invention proceeds to step S51, i.e., obtaining the requested display time and the actual display time of the indicator icon 100. Among them, the "requested display time" and the "actual display time" can be obtained by the sensor and the timing system inside the vehicle. For example, when the electronic control unit (i.e., ECU) issues a corresponding icon display request according to the signal detected by the sensor, the timing system records a timestamp. The time recorded by the timestamp is the "requested display time", which can be generated by a microprocessor or a timer. In one or more embodiments, the time point at which the indicator icon 100 is determined to be displayed normally after the present invention executes step S30 is used as the "actual display time" of the indicator icon 100. Alternatively, the actual display time can also select other appropriate time points. Then, the verification method executes step S52, i.e., determining whether the difference between the actual display time and the requested display time is less than or equal to the preset time difference. In one or more embodiments, the range of the preset time difference is 500ms (i.e., milliseconds)-800ms, such as 500ms, 600ms, 700ms, 800ms, etc., so that the preset time difference has a moderate value to ensure the accuracy of the judgment result. Alternatively, the preset time difference can also be set to other suitable time values. Based on the comparison result, it is determined whether the indicator icon 100 displays a delay. Specifically, when the judgment result is yes, the verification method proceeds to step S53, that is, it is determined that the indicator icon 100 does not display a delay. Otherwise, the verification method proceeds to step S54, that is, it is determined that the indicator icon 100 displays a delay. When it is determined that the indicator icon 100 displays a delay, a reminder can be issued to the user in an appropriate manner (such as text display, voice reminder, etc.) so that the user can repair it in time to eliminate driving hazards.
图4是本发明指示图标100的校验方法的第三实施例的流程示意图。如图4所示，在一种或多种实施例中，当指示图标100显示正常时，本发明校验方法还执行步骤S61，即获取指示图标100的请求显示信息和实际显示信息。接着，校验方法前进到步骤S62，即判断实际显示信息是否与请求显示信息相同。在一种或多种实施例中，汽车仪表盘共有N种指示图标100，分别记为图标1、图标2、图标3……图标N，并且分别采用“1”和“0”标记每个图标是否需要显示，以生成请求显示信息。例如，汽车仪表盘共有8种指示图标100，并且图标2需要显示(其它图标无需显示)，则请求显示信息可以标记为“01000000”。实际显示信息可以通过像素采集和分析获取。基于比较结果判断指示图标100是否额外显示。具体地，在执行步骤S62时，当判断结果为是时，则判定指示图标100没有额外显示(即步骤S63)。当判断结果为否时，说明实际显示的指示图标100不仅有请求显示信息中需要显示的指示图标100，还存在其它额外的指示图标100，则执行步骤S64，即判定指示图标100存在额外显示。当判定指示图标100存在额外显示后，可以通过合适的方式(例如文本显示、语音提醒等)向用户发出提醒，以便用户及时维修，消除行车隐患。FIG4 is a flow chart of a third embodiment of the verification method of the indicator icon 100 of the present invention. As shown in FIG4, in one or more embodiments, when the indicator icon 100 is displayed normally, the verification method of the present invention further executes step S61, i.e., obtaining the request display information and the actual display information of the indicator icon 100. Then, the verification method proceeds to step S62, i.e., determining whether the actual display information is the same as the request display information. In one or more embodiments, there are N kinds of indicator icons 100 in the car dashboard, which are respectively recorded as icon 1, icon 2, icon 3 ... icon N, and "1" and "0" are used to mark whether each icon needs to be displayed, so as to generate the request display information. For example, there are 8 kinds of indicator icons 100 in the car dashboard, and icon 2 needs to be displayed (other icons do not need to be displayed), then the request display information can be marked as "01000000". The actual display information can be obtained by pixel acquisition and analysis. Based on the comparison result, it is determined whether the indicator icon 100 is additionally displayed. Specifically, when executing step S62, when the judgment result is yes, it is determined that the indicator icon 100 is not additionally displayed (i.e., step S63). When the judgment result is no, it means that the actually displayed indication icons 100 include not only the indication icons 100 required to be displayed in the requested display information, but also other additional indication icons 100, and then step S64 is executed, i.e., it is determined that the indication icons 100 are additionally displayed. When it is determined that the indication icons 100 are additionally displayed, a reminder can be issued to the user in an appropriate manner (such as text display, voice reminder, etc.) so that the user can make timely repairs and eliminate driving hazards.
图5是本发明指示图标100的校验方法的第四实施例的流程示意图。如图5所示，在一种或多种实施例中，当指示图标100显示不正常时，本发明校验方法前进到步骤S71，即获取指示图标100的偏差率。其中，偏差率等于与预设图像信息不同的图像块的数量除以图像块的总数量。例如，图像块的总数量为10，与预设图像信息不同的图像块的数量为1，则偏差率即为10％。接着，控制方法执行步骤S72，即判断偏差率是否小于等于预设偏差率。在一种或多种实施例中，预设偏差率为50％。替代地，预设偏差率也可设置成比50％大或小的其它合适的数值。基于判断结果判断指示图标100为部分图像缺失或图像显示错误。具体而言，当判断结果为是时，说明偏差率较低，实际显示的指示图标100与请求显示的指示图标100差异不大，则判定指示图标100属于部分图像缺失。当判定指示图标100为部分图像缺失后，可以通过合适的方式(例如文本显示、语音提醒等)向用户发出提醒，以便用户及时维修，消除行车隐患。当判断结果为否时，说明偏差率较大，实际显示的指示图标100与请求显示的指示图标100之间存在较大的差异。换言之，实际显示的指示图标100可能与请求显示的指示图标100不属于同一类型，例如请求显示的指示图标100为电频故障指示图标100，而实际显示的指示图标100为机油报警指示图标100。因此，校验方法前进到步骤S74，即判定指示图标100为图像显示错误。当判定指示图标100为图像显示错误后，可以通过合适的方式(例如文本显示、语音提醒等)向用户发出提醒，以便用户及时维修，消除行车隐患。FIG5 is a flow chart of a fourth embodiment of the verification method of the indicator icon 100 of the present invention. As shown in FIG5, in one or more embodiments, when the indicator icon 100 is displayed abnormally, the verification method of the present invention proceeds to step S71, i.e., obtaining the deviation rate of the indicator icon 100. The deviation rate is equal to the number of image blocks that are different from the preset image information divided by the total number of image blocks. For example, if the total number of image blocks is 10 and the number of image blocks that are different from the preset image information is 1, then the deviation rate is 10%. Next, the control method executes step S72, i.e., determining whether the deviation rate is less than or equal to the preset deviation rate. In one or more embodiments, the preset deviation rate is 50%. Alternatively, the preset deviation rate can also be set to other suitable values greater or less than 50%. Based on the judgment result, it is determined that the indicator icon 100 is partially missing or the image display is wrong. Specifically, when the judgment result is yes, it means that the deviation rate is low, and the actual displayed indicator icon 100 is not much different from the requested indicator icon 100, then it is determined that the indicator icon 100 is partially missing. When it is determined that the indication icon 100 is partially missing, a reminder can be issued to the user in an appropriate manner (such as text display, voice reminder, etc.) so that the user can repair it in time and eliminate the hidden dangers of driving. When the judgment result is no, it means that the deviation rate is large, and there is a large difference between the indication icon 100 actually displayed and the indication icon 100 requested to be displayed. In other words, the indication icon 100 actually displayed may not be of the same type as the indication icon 100 requested to be displayed. For example, the indication icon 100 requested to be displayed is the electric frequency fault indication icon 100, while the indication icon 100 actually displayed is the oil alarm indication icon 100. Therefore, the verification method proceeds to step S74, that is, it is determined that the indication icon 100 is an image display error. When it is determined that the indication icon 100 is an image display error, a reminder can be issued to the user in an appropriate manner (such as text display, voice reminder, etc.) so that the user can repair it in time and eliminate the hidden dangers of driving.
