[0049] To make the technical problems, technical solutions and advantages to be solved by the present application clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described here without departing from the scope and spirit of the present application. In addition, descriptions of known functions and structures are omitted for clarity and conciseness.
[0050] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure or characteristic related to the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.
[0051] In various embodiments of the present application, it should be understood that the magnitudes of the serial numbers of the following processes do not mean the order of execution is prior or subsequent. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
[0052] The present application aims at the problem that the existing technology cannot remotely monitor the electronic control unit of an electric vehicle, and provides a wake-up monitoring method and device.
[0053] To solve the above problems, the technical solution of the present application is developed independently. In this solution, the gateway node monitors the active wake-up status of each subnet node through network management messages, and sends the result to the telematics box (T-Box) through network management messages. The T-Box sends it to the cloud server or the mobile phone terminal through wireless communication. Relevant engineers can quickly locate the problematic electronic control unit by logging in to the cloud server or using a mobile application (APP).
[0054] Such as Figure 3As shown in the figure, the present application provides a block diagram of a wake-up monitoring system. The block diagram of the wake-up monitoring system includes a gateway 1, a T-Box 2 connected to the gateway, and a plurality of subnets connected to the gateway 1, such as subnet 2 to subnet n. Here, the number of subnets is not limited and can be set according to specific needs. Each subnet includes a plurality of electronic control units (ECUs), and the number of ECUs is not limited and can be set according to specific needs. For example, in Figure 3 subnet 2, three electronic control units are provided, namely the first electronic control unit, the second electronic control unit, and the third electronic control unit, and each electronic control unit corresponds to a function that can be realized.
[0055] Such as Figure 1 As shown, based on the above Figure 3 content, the present application provides a wake-up monitoring method, including:
[0056] Step 100, obtaining the communication status of the vehicle;
[0057] Step 200, determining the sleep indication information of the electronic control unit according to the communication status of the vehicle;
[0058] Step 300, sending the sleep indication information to the cloud server.
[0059] In this embodiment, the gateway monitors the sleep and wake-up states of each electronic control unit in each network segment in real time, and sends the status information of each controller to the cloud server. Here, it can be uploaded to the cloud server through wireless communication technology. The abnormal sleep and wake-up information of the electronic control unit can be queried through the remote monitoring platform on the cloud server. The technical solution of the present application can remotely determine the control units that the whole vehicle fails to sleep normally, and can also remotely determine the control units that are abnormally woken up.
[0060] Optionally, the step 200 includes:
[0061] Step 210, when the communication status of the vehicle is in the power-off state, monitoring the network packets of the electronic control unit;
[0062] Step 220, determining the type of the electronic control unit according to the network packets;
[0063] Step 230, determining the sleep indication information of the electronic control unit according to the type of the electronic control unit.
[0064] In this embodiment, after the vehicle power supply switches to the power-off state (OFF power), the gateway controller enables the monitoring state. By the types of the electronic control units, the sleep indication information of the electronic control units is further determined, and the sleep state or wake-up state of the current electronic control unit can be determined through the sleep indication information. The technical solution of this application can remotely determine the control units that fail to normally enter the sleep state of the vehicle and can also remotely determine the control units that are abnormally woken up.
[0065] Optionally, step 220 includes:
[0066] When the electronic control unit is within the preset range of network management, it is determined as an electronic control unit directly managed by the network;
[0067] When the electronic control unit is outside the preset range of network management, it is determined as an electronic control unit directly managed by the network;
[0068] Wherein, the preset range of network management is a preset range for classifying the types of the electronic control units.
[0069] In this embodiment, the gateway controller identifies the corresponding control unit by identifying the message identity number (message ID). There are two types of control units on the bus, one is the directly network-managed control unit and the other is the indirectly network-managed control unit. Here, the preset range of network management is exemplified by 0400 - 045F. If the message information of the electronic control unit is within the range of 0400 - 045F, it is determined as a directly network-managed electronic control unit; if the message information of the electronic control unit is within a range less than 0400 or greater than 045F, that is, outside the preset range of network management, it is determined as an indirectly network-managed electronic control unit.
[0070] Optionally, step 230 includes:
[0071] When the type of the electronic control unit is a directly network-managed electronic control unit, obtain the first bus information of the directly network-managed electronic control unit;
[0072] If the network message in the first bus information includes the message identity number (message ID) of the directly network-managed electronic control unit, then determine that the sleep indication information of the electronic control unit is an abnormal wake-up indication bit; otherwise, determine that the sleep indication information of the electronic control unit is a sleep indication bit.
[0073] Here, the sleep indication information represents the state through the sleep indication bit. The electronic control unit with a sleep indication bit of 1 is an abnormal non-sleeping control unit, and the electronic control unit with a sleep indication bit of 0 is a normally sleeping electronic control unit.
[0074] In this embodiment, since the electronic control unit (ECU) participating in direct network management is within the preset range of network management, it is only necessary to detect whether there is a message ID corresponding to the ECU within the preset range of network management. If the message ID corresponding to the ECU appears, it is determined that the sleep indication information of the ECU participating in direct network management is an abnormal wake-up indication bit, that is, the sleep indication bit of the ECU is set to 1. Otherwise, it is determined that the sleep indication information of the ECU is a sleep indication bit, that is, the sleep indication bit of the ECU is set to 0.
[0075] Optionally, step 230 further includes:
[0076] When the type of the ECU is an ECU for indirect network management, obtain the second bus information of the ECU for indirect network management;
[0077] If at least one frame of network message in the second bus information includes the message identification number of one of the ECUs for indirect network management, it is determined that the sleep indication information of the ECU is an abnormal wake-up indication bit; otherwise, it is determined that the sleep indication information of the ECU is a sleep indication bit.
[0078] In this embodiment, since the ECU participating in indirect network management is outside the preset range of network management, it will receive message information of multiple ECUs outside the preset range of network management. If at least one frame of network message in the second bus information includes the message ID of one of the ECUs for indirect network management, that is, if there is a corresponding message ID in one frame of the ECUs among multiple ECUs, the sleep indication information of the ECU for indirect network management is set to an abnormal wake-up indication bit, that is, the sleep indication bit of the ECU is set to 1. Otherwise, that is, if none of the multiple ECUs has a corresponding message ID, it is determined that the sleep indication information of the ECU is a sleep indication bit, that is, the sleep indication bit of the ECU is set to 0.
[0079] Optionally, the method further includes:
[0080] When the communication state of the vehicle is in the powered-on state, control the sleep indication information of all ECUs to be sleep indication bits.
[0081] In this embodiment, when the vehicle power supply switches to the powered-on state (non-OFF state), the gateway controller stops monitoring and sets the sleep indication information of all ECUs to sleep indication bits, that is, sets all sleep indication bits to 0. If a sleep indication bit is 1 at this time, it is sent to the cloud server, and the ECU with a sleep indication bit of 1 at this time is an abnormally awakened unit.
[0082] Optionally, the method further includes:
[0083] According to the abnormal wake-up indication bit, record the message information of the current electronic control unit and upload it to the cloud server.
[0084] In this embodiment, the abnormal wake-up indication bit, that is, the abnormal wake-up after sleep. Due to the upload cycle problem with the cloud server, it is impossible to completely determine the first awakened electronic control unit from the cloud server. The gateway controller needs to monitor the first awakened cloud server and report the first abnormally awakened cloud server, so as to ensure the specific location of the abnormal electronic control unit.
[0085] Such as Figure 2 As shown, an embodiment of the present application further provides a wake-up monitoring method, which is applied to a cloud server and includes:
[0086] Step 400, receiving the sleep indication information of the electronic control unit sent by the gateway controller;
[0087] Step 500, determining the wake-up state of the electronic control unit according to the sleep indication information.
[0088] In this embodiment, the cloud server can receive the sleep indication information of the electronic control unit sent by the gateway controller through wireless communication technology. Here, the wireless communication technology includes but is not limited to the fourth-generation communication technology (4G) and the fifth-generation communication technology (5G) and uploads it to the remote monitoring platform; further, through step 500 according to the sleep indication information, the abnormal sleep and wake-up information of the electronic control unit can be queried. The technical solution of the present application can judge the abnormally awakened electronic control unit according to the abnormally awakened electronic control unit reported by the gateway controller.
[0089] Optionally, the step 500 includes:
[0090] If the sleep indication information is an abnormal wake-up indication bit, it is determined that the current electronic control unit is an abnormally awakened electronic control unit;
[0091] If the sleep indication information is a sleep indication bit, it is determined that the current electronic control unit is a normally awakened electronic control unit.
[0092] In this embodiment, by monitoring the sleep indication information, the sleep indication information may include a sleep indication bit. The electronic control unit with the sleep indication bit being 1 is an abnormally non-sleeping electronic control unit, and the electronic control unit with the sleep indication bit being 0 is a normally sleeping electronic control unit. By detecting the sleep indication bit of the electronic control unit, it is possible to remotely determine the electronic control unit that has not slept normally in the whole vehicle, and it is also possible to remotely determine the cause of the vehicle battery power failure.
[0093] In summary, the wake-up monitoring method of the present application can conveniently and efficiently judge the problem of vehicle battery power shortage caused by network abnormal sleep and wake-up problems.
