Description

CAN signal reserved field processing method, device, electronic device and storage medium Technical Field

[0001] The present application relates to the field of reserved word processing, and in particular to a CAN signal reserved field processing method, a CAN signal reserved field processing device, an electronic device, a storage medium and a vehicle. Background Art

[0002] Smart cars are developing rapidly, and more and more functions are being integrated into the central control system via the CAN bus. Software on the system, such as vehicle settings, driving settings, air conditioning, charging, and panoramic imaging, inevitably needs to receive signal instructions from the controller and generate corresponding interface displays. For software developers, handling controller anomalies is equally important and even more complex. These anomalies include path interruptions, no controller feedback, and reporting abnormal values. The most difficult to handle is when the signal reports a reserved field. This is primarily due to two reasons:

[0003] Different signals have different value ranges, and their corresponding Reserved fields are also different. For example, in a certain car model, the power mode signal (PowerMode) ranges from 0 to 15, with 1-3 and 5-14 being the Reserved fields; the atmosphere light brightness signal (AtmosphereLightBrightnessSt) also ranges from 0 to 15, with 8-15 being the Reserved field.

[0004] Most functional specifications require that the interface gray out after receiving the Reserved field, but the functional specifications of some models require that the Reserved field of some signals be treated as OFF.

[0005] The diversity of the aforementioned signals and requirements complicates exception handling for the Reserved field. Specific graying out is required for specific signals based on requirements, which significantly increases development workload and lacks flexibility, leading to increased development costs.

[0006] Therefore, a CAN signal reserved field processing solution is needed to effectively solve the development difficulties caused by the above-mentioned signal overlap, confusion and diversity of requirements.

[0070] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0071] FIG1 is a flowchart of a method for processing a reserved field of a CAN signal provided by one or more embodiments of the present invention.

[0072] The CAN signal reserved field processing method shown in FIG1 includes:

[0073] Step S1, obtaining CAN signal information corresponding to vehicle function and status;

[0074] Step S2, the CAN signal information of the vehicle function and status includes a reserved field corresponding to the preset vehicle function and status;

[0075] Step S3, setting a display strategy for the vehicle function and status according to the reserved fields for the preset vehicle function and status;

[0076] Step S4, wherein the reserved fields corresponding to the vehicle functions and states of the CAN signal information are identified;

[0077] Step S5: executing a display strategy corresponding to the vehicle function and status based on the identified reserved fields.

[0078] Specifically, multiple on-board devices or software modules are connected to the same CAN bus, each with a preset function that generates reserved fields. These reserved fields corresponding to the preset vehicle functions and status are displayed on the display terminal. Display policies, such as graying out or displaying them as off, are used. Typically, reserved fields correspond to states where the on-board device or software module is not functioning properly. However, different on-board devices may conflict on the same CAN bus. For example, for a certain vehicle model, the power mode signal (PowerMode) ranges from 0 to 15, with fields 1-3 and 5-14 representing the Reserved fields. The ambient light brightness signal (AtmosphereLightBrightnessSt) also ranges from 0 to 15, with fields 8-15 representing the Reserved fields. Therefore, a display policy for these vehicle functions and statuses is set based on the reserved fields for the preset vehicle functions and statuses, enabling differentiation between the on-board devices or software modules referenced by the reserved fields and implementing the display policy.

[0079] In this embodiment, based on the vehicle function and status corresponding to the identified CAN signal information, executing the display strategy corresponding to the vehicle function includes:

[0080] Generate a list based on the reserved fields corresponding to the preset vehicle functions and status;

[0081] Add an item showing the strategy to the list;

[0082] The items showing the strategy correspond to the items of preset vehicle functions, status and reserved fields;

[0083] Retrieve items from the list based on the CAN signal information corresponding to the vehicle function and status;

[0084] If the search result is an item corresponding to the preset vehicle function, status and reserved field, the corresponding display strategy is executed.

[0085] Specifically, based on the Can Matrix matrix table (i.e., list), the signal name and Reserved field (reserved field) of the corresponding vehicle-mounted equipment or software module are parsed out, and dynamic updating means are used to distinguish the vehicle-mounted equipment or software module pointed to by the reserved field, so as to solve the difficulties caused by the different signal and display strategy requirements of the vehicle-mounted equipment or software module.

[0086] The list already lists the signal name, the value of the reserved field, the signal status, etc., and then adds a display strategy item to the list so that the pointed vehicle device or software module can implement the corresponding display strategy according to the value of the reserved field.

[0087] In this embodiment, based on the reserved fields corresponding to the preset vehicle functions and states, the generated list includes:

[0088] Get vehicle model information;

[0089] Corresponding to the vehicle model, obtain the CAN signal information of the corresponding vehicle function and status;

[0090] Add items for vehicle models based on the list generated by the reserved fields corresponding to the preset vehicle functions and status;

[0091] Retrieve items from the list based on the CAN signal information corresponding to the vehicle function and status;

[0092] If the search result is an item corresponding to the preset vehicle function and status, then the item in the reserved field in the search list is retrieved according to the vehicle model;

[0093] If the search result is an item in the reserved field of the corresponding vehicle model, the vehicle model executes the display strategy of the corresponding reserved field.

[0094] Specifically, when using the list, the system first retrieves CAN signal information corresponding to the vehicle's functions and status based on the vehicle model. The list is then searched and a display strategy is implemented based on the search results. For example, the system first searches for items corresponding to the preset vehicle functions and status, finds items with reserved fields, and then determines the display strategy for those items within the reserved fields. Executing the display strategy can then align the vehicle's onboard devices and software modules to the vehicle model, preventing display conflicts.

[0095] In this embodiment, the display strategy includes:

[0096] Get the reserved fields based on the items in the retrieved list, and display the vehicle function interface of the corresponding model in gray;

[0097] According to the gray display of the vehicle function interface of the corresponding vehicle model, the information of the corresponding vehicle function and status is uploaded synchronously.

[0098] Specifically, a gray display indicates that the corresponding onboard device or software module on the bus is not functioning properly. Touch input on the display terminal will not produce the expected results. In this case, the vehicle computer can upload the gray display to the cloud, providing information and assistance to the vehicle.

[0099] FIG2 is a structural diagram of a CAN abnormality information system provided by one or more embodiments of the present invention.

[0100] The CAN abnormal information system shown in FIG2 includes: a controller module and an on-board function module;

[0101] On-board function module, used to control vehicle functions;

[0102] Controller module, used to connect the vehicle computer and the onboard functional modules;

[0103] The vehicle computer monitors the working status of the controller module and the vehicle function module;

[0104] The vehicle function module or controller module sends a reserved field according to abnormal working status;

[0105] The vehicle computer monitors the working status of the controller module and the vehicle function module, including monitoring whether the reserved field is received;

[0106] If the vehicle computer receives the reserved field, it identifies the vehicle function and status corresponding to the reserved field;

[0107] If the vehicle function and status corresponding to the reserved field are identified, the preset display strategy corresponding to the vehicle function and status is executed.

[0108] Specifically, the vehicle-mounted function module or controller module is part of the vehicle computer system, and will have abnormal working status. Corresponding to the abnormal working status, the reserved field of the corresponding vehicle-mounted function module or controller module is sent. The vehicle computer receives the reserved field and identifies the vehicle function and status corresponding to the reserved field. If the reserved field of the vehicle-mounted function module is identified, the reserved field of the corresponding vehicle function module is displayed in gray on the display terminal. For example, if the vehicle air conditioner fails, the reserved field of the corresponding air conditioner is sent, and the buttons for controlling the air conditioner are all displayed in gray, so that the user can immediately understand that the vehicle air conditioner cannot be used, instead of trying repeatedly. For example, if the reserved field of the controller module is identified, the CAN bus is completely paralyzed, and in the display strategy, directly select the display off (OFF).

[0109] In this embodiment, it also includes: a cloud service module;

[0110] The cloud service module is used to update the reserved fields of the corresponding vehicle functions and status;

[0111] The cloud service module is also used to update the preset display strategy corresponding to the vehicle function and status;

[0112] The cloud service module connects to the vehicle computer and receives vehicle model information from the vehicle system;

[0113] The cloud service module sends the reserved fields corresponding to the vehicle model based on the vehicle model information;

[0114] The reserved fields corresponding to the vehicle model include, the reserved fields corresponding to the vehicle function and status and the preset display strategy.

[0115] Specifically, when the vehicle computer receives the reserved field, it simultaneously sends the vehicle status information to the cloud server. The cloud server can pre-store information corresponding to various vehicle models, including reserved fields corresponding to vehicle functions and status, as well as preset more display strategies.

[0116] FIG3 is a structural diagram of a CAN signal reserved field processing device provided by one or more embodiments of the present invention.

[0117] As shown in Figure 3, the CAN signal reserved field processing device includes: a signal acquisition module, a display strategy module, a reserved field module, and a strategy execution module;

[0118] A signal acquisition module, configured to acquire CAN signal information corresponding to a vehicle function and status, wherein the CAN signal information corresponding to a vehicle function and status includes reserved fields corresponding to preset vehicle functions and statuses;

[0119] A display strategy module is used to set the display strategy of the vehicle function and status according to the reserved fields of the preset vehicle function and status;

[0120] A reserved field module is used to identify the reserved fields of vehicle functions and states corresponding to CAN signal information;

[0121] The strategy execution module is used to execute the display strategy corresponding to the vehicle function and status based on the identification of the reserved fields.

[0122] It is worth noting that although this system only discloses a signal acquisition module, a display strategy module, a reserved field module, and a strategy execution module, relatively speaking, what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the existing technology to form an infinite number of embodiments or technical solutions. In other words, this system is open rather than closed. Just because this embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned basic functional modules.

[0123] Through the above solution, the following beneficial technical effects are achieved:

[0124] This application parses out the reserved fields and registers them in a list according to the vehicle functions and status currently integrated on the bus, so that when the signal is displayed in gray, it is convenient to retrieve the corresponding specific device or function and prevent the reserved fields from overlapping and causing display confusion.

[0125] This application displays the vehicle function interface of the corresponding vehicle model in gray, so that users can promptly understand the missing status of the vehicle function and avoid misunderstanding the vehicle status and causing incorrect operations.

[0126] This application uses cloud services to share reserved field information among multiple vehicle models, so that when the vehicle configuration is increased or decreased, compatibility issues caused by unclear reserved fields can be resolved, reducing programming difficulties.

[0127] FIG4 is a schematic diagram of a CAN signal reserved field map according to a specific embodiment of the present invention.

[0128] FIG5 is a schematic diagram of generating a CAN signal reserved field map according to a specific embodiment of the present invention.

[0129] FIG6 is a schematic diagram of updating a CAN signal reserved field map according to a specific embodiment of the present invention.

[0130] FIG7 is a schematic diagram of the use of a CAN signal reserved field map according to a specific embodiment of the present invention.

[0131] In a specific embodiment, based on the Can Matrix matrix table, the signal name and the Reserved field (reserved field) are parsed out, and at the same time, dynamic update means are used to uniformly solve the interface display problem of the Reserved field, that is, to effectively solve the software editing difficulties caused by inconsistent signals and diverse vehicle equipment requirements.

[0132] The core of this embodiment is to generate and maintain a Map (equivalent to a list), which records the Reserved fields corresponding to all signals to be grayed out. For example, it can be defined that the key of the Map is the signal name, and the value is the Reserved field value of the signal, separated by a semicolon. Both Key and value are of String type. For example, the signal of the ambient light brightness of a certain car model is AtmosphereLightBrightnessSt, which occupies 4 bits in the Can matrix table. As shown in Figure 4, it can be seen that the definitions of 8-15 (binary 1000-1111) are all Reserved. Then the definition of the signal in the Map is<AtmosphereLightBrightnessSt,8;9;10;11;12;13;14;15> .

[0133] In another specific embodiment, generating and maintaining a Map mainly includes three steps: Map generation, Map update, and Map use.

[0134] As shown in Figure 5, map generation: Each vehicle model has its own corresponding Can matrix table. First, save the Can matrix table as a CSV file (a text file). CSV files are suitable for input during code execution. The code then parses the CSV file to obtain the name of each signal and its Reserved field, populating the signal reserved field map created in memory.

[0135] As shown in Figure 6, Map Update: When the central control application receives the Reserved value, it is usually grayed out. However, sometimes it does not need to be grayed out. In this case, the signal reservation field Map must be updated in advance. This update mainly occurs in two scenarios:

[0136] In scenario A, the functional specification clearly states that when the controller reports the Reserved value for certain signals, the interface does not need to be grayed out. In this case, these signals need to be removed from the signal reserved field Map based on the vehicle model.

[0137] In scenario B, if a controller has undergone a software update and a reserved field is enabled, the new function can be enabled without modifying the system ROM. Only application-level modifications and upgrades are required, greatly reducing R&D costs. Specifically, a change item is configured in the cloud and sent to the central control application, which then stores it in the database. After the system restarts and generates the signal reserved field map, the change item saved in the database is read and the map is updated. Based on this, the interface can directly and correctly display the new function.

[0138] As shown in Figure 7, Map usage: When the resident service receives a signal reported by the controller, it needs to first query the Map.

[0139] If it can be found, it means that the function corresponding to the signal needs to be grayed out. At this time, the received signal value must be converted into a pre-defined abnormal value (usually -0xFFFFFFFF) and reported to the corresponding application, which will then gray out the function on the interface.

[0140] If it cannot be found, it means that the function corresponding to the signal should be displayed normally. At this time, just report the received signal value directly to the corresponding application.
