[0002] The in-vehicle network bus management function enables the nodes of vehicle electronic control units (ECUs) to sleep and wake up orderly.

[0035] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0037] The following will, with reference to the accompanying drawings, detail a communication method, device, electronic device, and medium compatible with a CAN transceiver provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0038] See Figure 1 , Figure 1 is one of the flowchart diagrams of a communication method compatible with a CAN transceiver provided by the embodiments of the present application. As Figure 1 shown, this method is applied to an in-vehicle network bus management system. The in-vehicle network bus management system includes N control chips and CAN transceivers corresponding to the N control chips one by one, and specifically includes the following steps:

[0039] Step 101, read the first parameter of the target control chip, where the target control chip is any one of the N control chips.

[0040] It is worth mentioning that the control chip in the present application can be an electronic control unit (ECU), or other control structures capable of performing control logic processing and sending application messages to the CAN bus. The above target control chip can be one of the control chips in the in-vehicle network management bus. The target control chip is correspondingly connected to a CAN transceiver, which is the target CAN transceiver. The CAN transceiver can serve as an interface between the control chip and the physical bus, converting the logic level of the control chip into the differential level of the CAN bus and transmitting data on two bus cables with differential voltages.

[0041] In the above steps, by reading the first parameter of the target control chip, the communication rule or command of the target control chip can be determined. Based on this, the first parameter is transmitted to the CAN transceiver that can receive and match this type of rule, so that the target control chip and the target CAN transceiver are corresponding. In this way, when there is a demand for the target control chip, the target control chip can be woken up through the target CAN transceiver, forming a high-speed and synchronous transmission channel.

[0042] Step 102: Obtain the preset M read / write register driver programs, and respectively obtain the second parameter of the target CAN transceiver based on each of the read / write register driver programs, obtaining M second parameters. Wherein, the target CAN transceiver is the CAN transceiver corresponding to the target control chip, one read / write register driver program corresponds to one type of CAN transceiver, and M is an integer greater than 1.

[0043] It should be noted that the embodiment of the present application is directed to the problem that it is difficult for the control chip to communicate with the CAN transceiver of different models, and it is necessary to reconfigure the register read / write driver program corresponding to this type of CAN transceiver. By presetting the read / write register driver programs of each model for the target CAN transceiver, a software version can be made compatible with multiple types of CAN transceivers. Please refer to Figure 2 , for example, the relationship between the existing CAN transceiver and the control chip is that 3 types of CAN transceivers require 3 hardware settings and 3 software settings. However, in the present application, by presetting the read / write register driver programs of each model such as TCAN, TJA, and UJC, writing TJA_1146_ReadReg(), and being ready at any time for the target CAN transceiver to call this read / write register. Finally, only 1 hardware setting and 1 software setting are required for 3 types of CAN transceivers.

[0044] In addition, since each read / write register driver program corresponds to one type of CAN transceiver, it is necessary to determine the register driver program of the target CAN transceiver corresponding to the target control chip. This can be achieved by determining the second parameter corresponding to each register driver program, and identifying the read / write register driver program required for the specific CAN transceiver to communicate with the control chip through the second parameter. In this way, various types of CAN transceivers can be made compatible through the preset read / write register driver programs corresponding to each type of CAN transceiver. After replacing different CAN transceivers, there is no need to configure the driver program for this type, which can reduce the development and maintenance costs and improve the system operation efficiency.

[0045] Step 103: Compare the first parameter and the M second parameters, and obtain the target second parameter that matches the first parameter. The M second parameters include the target second parameter.

[0046] In this step, based on the first parameter of the obtained target control chip and the second parameter corresponding to each register driver, the first parameter and the second parameter are compared and matched. The comparison and matching between the first parameter and the second parameter can specifically be that the rule corresponding to the first parameter is the same as the rule corresponding to the second parameter, or the instruction setting of the first parameter is the same as the instruction setting of the second parameter.

[0047] Step 104: Determine the read / write register driver corresponding to the target second parameter as the target read / write register driver, where the target read / write register driver is used to drive data transmission between the target control chip and the target CAN transceiver.

[0048] In a specific implementation, the target second parameter can represent the specific applicable rules of the read / write register driver in a type of CAN transceiver. When the first parameter matches the target second parameter, it can be determined that the read / write register driver corresponding to the target second parameter can drive the wake-up of the target control chip. When communication is required, it can transmit communication signals to the target control chip and also receive the communication signals sent by the target control chip to the CAN bus. In this way, the read / write register driver corresponding to the target second parameter can be used as the target read / write register driver to drive data transmission between the target control chip and the target CAN transceiver. Even if different types of CAN transceivers are replaced, through the specific method of the embodiments of the present application, a communication channel can be established between the target control chip and the target CAN transceiver, and the target read / write register driver in the replaced CAN transceiver can be determined. Therefore, the present application can be compatible with different models of CAN transceivers, and the communication connection to the control chip can be realized through the CAN transceiver.

[0049] Optionally, before reading the first parameter of the target control chip, it further includes:

[0050] Perform a system initialization operation on the in-vehicle network bus management system;

[0051] Configure and connect a preset pin on the target control chip to the corresponding target CAN transceiver through the Serial Peripheral Interface (SPI), and set a third parameter of the SPI, where the third parameter includes the baud rate.

[0052] In a specific implementation, first, an initialization operation is performed on the in-vehicle network bus management system to facilitate the configuration and identification between the subsequent control chip and its corresponding CAN transceiver, reduce the interference of other operations, and improve the identification and communication efficiency. In addition, configuring the corresponding target control chip and target CAN transceiver includes two aspects: on the one hand, in terms of hardware settings, each control chip can select the same pin to connect to the Serial Peripheral Interface (SPI). Four consistent lines are occupied on the pins of each control chip. In this way, the control chip uses SPI configuration, which can save pins, save space for the Printed Circuit Board (PCB) where it is located, and can also provide a high-speed and synchronous communication channel. On the other hand, in terms of software settings, the communication channel between the control chip and its corresponding CAN transceiver can transmit communication signals quickly and synchronously by configuring the SPI parameters between them. For example, by configuring the baud rate of SPI, the rate of transmitting symbols between the control chip and its corresponding CAN transceiver can be preset, which is convenient for the subsequent identification between the target control chip and its corresponding target CAN transceiver and for waking up in time after identification.

[0053] Optionally, the reading of the first parameter of the target control chip includes:

[0054] Invoking the preset register in the target control chip;

[0055] Reading the first parameter of the target control chip based on the preset register;

[0056] Wherein, the first parameter includes electrical parameters, physical parameters, the model of the preset register, and the first address of the target control chip.

[0057] It should be noted that the acquisition of the first parameter of the above-mentioned target control chip can be based on the preset register built in the target control chip. By invoking this preset register, the first parameter related to this target control chip can be obtained. This first parameter can be the parameter information included in the Datasheet of the control chip, specifically, it can be the pin configuration, electrical parameters, physical parameters, etc. of the control chip. Since the factory configurations of different control chips are different, their Datasheet contents are different, and their specific characteristic specifications are also different, a CAN transceiver suitable for the corresponding control chip is required. Therefore, the CAN transceiver needs to invoke a read-write register driver program that can match this control chip to achieve the communication transfer between this control chip and the CAN transceiver.

[0058] Optionally, after determining that the read / write register driver corresponding to the target second parameter is the target read / write register driver, the method further includes:

[0059] When the in-vehicle network bus management system wakes up the network, obtain a fourth parameter of the control chip to be woken up, where the fourth parameter includes a second address of the control chip to be woken up;

[0060] Compare the target second parameter determined based on the target read / write register driver with the fourth parameter;

[0061] When the first address included in the target second parameter is the same as the second address included in the fourth parameter, wake up the target control chip corresponding to the second address.

[0062] It is worth mentioning that the network wake-up management in this application is set for the consideration of power saving of new energy vehicles. Since all electronic control units on new energy vehicles communicate with each other through CAN bus, Ethernet, etc., network management is to achieve coordinated sleep or wake-up of each ECU on the network of each ECU by setting fixed rules or commands. Sleep when there is no communication requirement and wake up when communication is needed, which is convenient for saving the battery power of new energy vehicles. In addition, when the vehicle has a demand for the ECU, the CAN transceiver can be woken up at any time to receive the vehicle's message and send the application message of the ECU.

[0063] In a specific implementation, after the target control chip and the target CAN transceiver establish a communication connection, when the vehicle needs to wake up the target control chip, the fourth parameter of the target control chip can be transmitted, and the fourth parameter can specifically be the second address of the target control chip. Subsequently, the fourth parameter can be given to the CAN bus, and the CAN bus sends this second address to each CAN transceiver. Each CAN transceiver identifies whether this second address is associated with the target second parameter of the target read / write register driver inside it. If the comparison result between the target second parameter determined by the target read / write register driver and the fourth parameter shows a match, at this time, it can be determined that the target control chip to be woken up is the control chip corresponding to the target read / write register driver, and the target control chip can be directly woken up through the target CAN transceiver. In this way, the wake-up of the target control chip is completed. Therefore, by setting the target read / write register driver in this application, it is possible to achieve compatible connection and configuration of control chips between different models of CAN transceivers, which is convenient for production management and control and reduces the development and maintenance costs.

[0064] Please refer specifically to Figure 3 , Figure 3FIG. 2 is a second schematic flowchart of a communication method compatible with a CAN transceiver provided by an embodiment of the present application. The method specifically includes the following steps:

[0065] Step 201, perform a system initialization operation on the in-vehicle network bus management system;

[0066] Step 202, configure and connect a preset pin on the target control chip to the corresponding target CAN transceiver through a Serial Peripheral Interface (SPI), and set a third parameter of the SPI;

[0067] Step 203, read a first parameter of the target control chip;

[0068] Step 204, obtain M read / write register driver programs preset in the target CAN transceiver, and respectively obtain a second parameter of the target CAN transceiver based on each of the read / write register driver programs to obtain M second parameters;

[0069] Step 205, compare the first parameter with the M second parameters, and obtain a target second parameter that matches the first parameter;

[0070] Step 206, determine the read / write register driver program corresponding to the target second parameter as the target read / write register driver program.

[0071] In the above specific embodiment, it is a specific process of establishing a communication connection between a target control chip and its corresponding target CAN transceiver in the in-vehicle network bus management system, and waking up the target control chip by transmitting a wake-up signal through the target CAN transceiver. For specific implementation, reference can be made to the foregoing embodiments, and details are not elaborated herein. Thus, the embodiment of the present application enables the control chip to identify and communicate with different models of CAN transceivers, select and determine the corresponding target read / write register driver program, without the need to re-develop software programs, facilitating the wake-up control of the control chip, improving the operation efficiency of the entire vehicle, and reducing the costs of production management and development maintenance.
