[0051] Aspects and exemplary embodiments of the present application will be described in detail below. For the purpose of making the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusively, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0053] As described in the background art section, in the prior art, during project implementation, it may be due to cost control or the failure to identify the PN wake-up requirement in the early stage that a CAN transceiver capable of implementing this function is not used, thus resulting in the inability to achieve network management wake-up of the PN request.

[0054] Based on this, in the controller wake-up method provided by the embodiments of the present application, it is realized to control whether the controller needs to be woken up by detecting whether the wake-up message includes a valid PN request, which improves the applicability of waking up the controller, and it is also not necessary to use a CAN transceiver to realize the wake-up of the controller by the PN request, thereby reducing the project implementation cost.

[0055] The present application provides a method for waking up a controller. This method is applied to the CAN interface module of the controller. First, the method for waking up the controller provided by the embodiments of the present application will be introduced below.

[0056] Figure 1 FIG. 4 shows a schematic flow chart of a method for waking up a controller provided by an embodiment of the present application. As Figure 1 shown, the method may include the following steps:

[0057] S101, receiving a wake-up message;

[0058] S102, detecting the message type of the wake-up message to obtain a message type detection result;

[0059] S103, when the message type detection result indicates that the message type is a management message, sending the message data of the wake-up message to the network management module, so that the network management module detects the content format of the message data to obtain a return value, and the return value is used to indicate whether the wake-up message includes a valid PN request;

[0060] S104, in response to a message detection request sent by the controller management module, sending the return value to the controller management module, so that the controller management module controls whether to wake up the controller according to the return value.

[0061] Based on the above embodiments, in the method for waking up a controller according to the embodiments of the present application, after receiving a wake-up message in the CAN interface module, the message type of the wake-up message is detected to obtain a message type detection result. When the detection result is a management message, the message data of the wake-up message is sent to the network management module, so that the network management module detects the message data to obtain a return value. Thus, the return value can be sent to the controller management module, so that the controller management module controls whether to wake up the controller according to the return value. Based on this, it is realized to control whether the controller needs to be woken up by detecting whether the wake-up message includes a valid PN request, improving the applicability of waking up the controller, and there is no need to use the CAN transceiver to realize the wake-up of the controller by the PN request, reducing the project implementation cost.

[0062] In the above S101, before the controller goes to sleep, the CAN transceiver will be put into the sleep mode. The CAN transceiver can monitor the change of the level on the CAN bus in the sleep mode. When the level of the CAN bus changes, the CAN transceiver will recover from the sleep mode to the normal state and send a wake-up request signal to the controller, thereby generating a wake-up event, so that the CAN interface module in the controller can receive the wake-up message sent by the CAN transceiver.

[0063] As an example, the CAN interface module can be the CanIf (Controller Area Network Interface) module, which is a communication module in the AUTOSAR standard and is used to achieve communication between different ECUs (Electronic Control Unit) via the CAN bus. The CanIf module is located between the underlying CAN device drivers (CAN driver and transceiver driver) and the upper-layer communication service layer (such as CAN status manager, CAN network management, CAN transport protocol, PDU router, etc.), and it represents the service or interface of the CAN driver to the upper-layer communication layer. The CanIf module provides a unique interface to manage different types of CAN hardware devices, such as CAN controllers and CAN transceivers.

[0064] As an example, a wake-up event can cause the controller to power on again or generate a wake-up interrupt;

[0065] Among them, causing the controller to power on again can be achieved by controlling the power module to supply power to the controller again;

[0066] Generating a wake-up interrupt can be done by the data on the CAN bus being transferred to the controller after level conversion by the CAN transceiver, thereby causing the controller to generate a wake-up interrupt.

[0067] As an example, causing the controller to generate a wake-up interrupt can be achieved by the data on the CAN bus being transferred to the controller after level conversion by the CAN transceiver, thereby causing the controller to generate a wake-up interrupt.

[0068] In the above S102, after receiving the wake-up message, the message type of the wake-up message is detected to determine what type of wake-up message it is, and a corresponding message type detection result regarding the message type is obtained.

[0069] As an example, the message type can include: the message type may include data messages, management messages, control messages, etc.

[0070] In the above S103, when the message type detection result indicates that the message type of the wake-up message is a management message, the message data of the wake-up message can be sent to the network management module. The network management module checks the length and data content of the message data to determine whether it includes a valid PN request, generates different return values based on whether it includes a valid PN request, and returns the return value to the CAN interface module.

[0071] In an example, message data generally refers to the information content transmitted in a communication network and following the format specified by a certain communication protocol.

[0072] As an example, a valid PN request refers to a case where the length of the message data is a preset length and the content of the message data also includes a PN request. In this case, the PN request can be considered a valid PN request.

[0073] As an example, the network management module is the Nm (Network Management) module. The Nm module is responsible for monitoring and managing the LAN (Local Area Network) inside the vehicle, as well as the communication between the vehicle and the external environment (such as diagnostic tools, cloud servers, etc.). Its main functions include network topology management, communication status detection, and fault diagnosis. At the same time, the Nm module is also responsible for managing different states of the controller, including startup, sleep, and shutdown states, to optimize the power usage inside the vehicle and improve energy efficiency.

[0074] As an example, the return value can include a first return value and a second return value. Specifically, the first return value indicates that the wake-up message includes a valid PN request, and the second return value indicates that the wake-up message does not include a valid PN request.

[0075] In S104 above, the controller management module in the controller periodically sends a message detection request to ask the CAN interface module whether it has received a return value. Therefore, after receiving the return value sent by the network management module, the CAN interface module will respond to the message detection request sent by the controller management module and send the return value to the controller management module. After receiving the return value, the controller management module will determine whether to wake up the controller according to the specific value of the return value.

[0076] As an example, the controller management module can be the EcuM (ECU Manager) module. It is a software module based on the AutoSAR standard and is used to manage the startup and shutdown processes of the entire controller (i.e., ECU), ensure smooth switching between various working modes of the system, and provide necessary status information and error handling functions.

[0077] This application also provides a method for waking up a controller. This method is applied in the controller management module of the controller. First, the method for waking up the controller provided by the embodiments of this application will be introduced below.

[0078] Figure 2 Another flowchart showing the method for waking up a controller provided by an embodiment of this application is shown. As Figure 2 shown, the method may include the following steps:

[0079] S201, in response to receiving a wake-up event, send a message acquisition signal to the CAN driver module to enable the CAN driver module to acquire a wake-up message;

[0080] S202. Send the wake-up message to the CAN interface module so that the CAN interface module can detect the wake-up message and obtain a return value.

[0081] S203. Determine whether the wake-up message includes a valid PN request according to the return value.

[0082] S204. When it is determined that the wake-up message includes a valid PN request, send a controller wake-up signal to the communication management module so that the communication management module can wake up the controller.

[0083] Based on the above embodiments, by using the controller management module to respond to the received wake-up event and sending a message acquisition signal to the CAN driver module, the CAN driver module can obtain the wake-up message, and then send the wake-up message to the CAN interface module. The CAN interface module detects the wake-up message, and thus obtains a return value from the CAN interface module. From this, it can be determined whether the wake-up message includes a valid PN request according to the specific value of the return value. Only when the wake-up message carries a valid PN request, a controller wake-up signal is sent to the communication management module, thereby realizing the wake-up of the controller. Based on this, by detecting whether the wake-up message includes a valid PN request and only waking up the controller when it is determined that the wake-up message includes a valid PN request, it is possible to avoid system instability caused by false wake-up or invalid wake-up messages, thus realizing the wake-up of the controller by using the PN request without passing through the CAN transceiver, improving the applicability of waking up the controller, and at the same time reducing the use of the CAN transceiver and lowering the project implementation cost.

[0084] In the above S201, as described in the above S101, after the wake-up event occurs, the controller management module will respond to it. Then, by sending a message acquisition signal to the CAN driver module, the CAN driver module is converted to the on state, and thus the wake-up message to be detected is obtained from the CAN bus through the CAN driver module.

[0085] As an example, the CAN driver module can be the Can Driver module. In AUTOSAR (Automotive Open System Architecture), the Can Driver module is the bottom layer of the communication protocol stack, responsible for performing hardware access operations and providing an API (Application Programming Interface) access interface independent of the hardware for the upper-layer modules. It allows the upper-layer modules to interact with the CAN hardware, thereby realizing the sending and receiving of data.

[0086] Specifically, in one embodiment, the above S201 may include:

[0087] In S2011, in response to a wake-up signal, a call signal is sent to the CAN status management module, so that the CAN status management module turns on the CAN driver module according to the call signal, and obtains a wake-up message through the CAN driver module.

[0088] Based on the above embodiments, when the system receives a wake-up signal, it can quickly send a call signal to the CAN status management module, thereby quickly starting the CAN driver module and obtaining a wake-up message. This ability to respond quickly ensures the efficiency and real-time performance of the system, enabling it to resume its working state in the shortest possible time.

[0089] In the above S2011, by sending a message acquisition signal to the CAN driver module, the call signal can be sent to the CAN status management module first, and the CanSM (ECU State Manager, ECU status management) function in the CAN status management module can be called to convert the CAN driver module to the on state.

[0090] As an example, the CAN status management module can be the CanSM module, which is a module defined in the AUTOSAR standard for managing CAN communication status. The CanSM module is responsible for controlling the communication activities of the CAN network and providing status management functions to ensure the reliability and consistency of network communication.

[0091] More specifically, in one embodiment, S2011 may further include:

[0092] S20111, in response to a wake-up signal, determine the validity detection requirement of the wake-up signal according to the attribute of the wake-up signal;

[0093] S20112, after determining that the validity detection requirement indicates that validity detection is required, send a call signal to the CAN status management module, so that the CAN status management module turns on the CAN driver module according to the call signal and obtains a wake-up message.

[0094] Based on the above embodiments, by performing a validity determination on the wake-up signal and sending a call signal to the CAN status management module only for valid wake-up signals, unnecessary resource consumption can be avoided and the information transfer efficiency can be improved.

[0095] In the above S20111, the attributes of the target wake-up signals corresponding to the controller are all pre-stored in the CAN status management module. The CAN status management module will compare the attributes of the wake-up signal with the pre-stored ones to determine whether there are the same attributes in the CAN status management module for the attributes of the wake-up signal. If so, it means that the wake-up signal needs to be detected for the existence of a PN request.

[0096] In the above S20112, after determining that the validity detection requirement indication is that validity detection is needed, a call signal can be sent to the CAN status management module, so that the CAN status management module turns on the CAN driver module according to the call signal and obtains the wake-up message.

[0097] In the above S202, after receiving the wake-up message, the controller management module sends the wake-up message to the CAN interface module. The CAN interface module completes the detection of the wake-up message by executing the method described in the above S101 to S104 and obtains the return value from the CAN interface module.

[0098] In the above S203, it is determined whether the return value is the first return value or the second return value, and further determine whether the wake-up message includes a valid PN request.

[0099] Specifically, the first return value indicates that the wake-up message includes a valid PN request, and the second return value indicates that the wake-up message does not include a valid PN request.

[0100] In the above S204, after determining that the wake-up message includes a valid PN request, that is, the return value is the first return value, an ECU wake-up signal is sent to the communication management module to wake up the controller, and the functions of the communication-related modules are called again inside the communication management module to start the communication function of the controller, so as to realize the wake-up of the controller through the PN request.

[0101] As an example, the communication management module can be the ComM (COM Manager, communication management) module. In AUTOSAR, the ComM module is responsible for handling the management tasks related to vehicle communication, including collecting CAN bus communication access requests from communication requesters and coordinating these requests. It encapsulates the underlying communication services and simplifies the user's use of the communication stack and network management.

[0102] In order to be able to effectively control the state of the controller, the present application also provides another implementation manner of the controller wake-up method.

[0103] After the above S203, the method may further include:

[0104] S205, when it is determined that there is no valid PN request, control the controller to be in the sleep state.

[0105] Based on the above embodiments, by continuing to control the controller to remain in the sleep state when the wake-up signal does not include a PN request, it can be contrasted with the situation where the wake-up message carrying a PN request can successfully wake up the controller, so as to be able to effectively control the wake-up of the controller.

[0106] In the above S205, if the return value obtained by the controller management module from querying the CAN interface module remains the second return value within a certain period of time, the controller management module will stop querying the CAN interface module, guide the controller to enter the sleep state again, and enable the CAN transceiver to enter the sleep mode as well, and start monitoring the CAN bus level again.

[0107] It should be noted that the application scenarios described in the embodiments of the present application above are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0108] Based on the same inventive concept, the present application also provides a controller. Specifically, it will be described in detail in combination with Figure 3 for detailed description.

[0109] Figure 3 shows a schematic hardware structure diagram of the controller 300 provided by an embodiment of the present invention.

[0110] As Figure 3 shown, the controller 300 may include:

[0111] A CAN interface module 310, configured to receive a wake-up message;

[0112] Detect the message type of the wake-up message to obtain a message type detection result;

[0113] When the message type detection result indicates that the message type is a management message, send the message data of the wake-up message to the network management module 320, so that the network management module 320 detects the content format of the message data to obtain a return value;

[0114] A controller management module 330, the controller management module 330 is communicatively connected to the CAN interface module 310, and is configured to send a message acquisition signal to the CAN driver module 340 in response to a wake-up signal, so that the CAN driver module 340 acquires a wake-up message;

[0115] Send the wake-up message to the CAN interface module 310, so that the CAN interface module 310 detects the wake-up message to obtain a return value;

[0116] When the return value is the first return value, determine that the wake-up message includes a valid PN request;

[0117] The controller management module 330 sends a start signal to the communication management module 350, so that the communication management module 350 starts the controller.

[0118] In the controller provided in this embodiment, after receiving a wake-up message through the CAN interface module 310, the message type of the wake-up message is detected to obtain a message type detection result. In the case where the detection result is a management message, the message data of the wake-up message is sent to the network management module 320, so that the network management module 320 detects the message data to obtain a return value, and then the return value can be sent to the controller management module 330, so that the controller management module 330 controls whether the controller is awakened according to the return value. Based on this, it is realized to control whether the controller needs to be awakened by detecting whether the wake-up message includes a valid PN request, improving the applicability of waking up the controller, and there is no need to use a CAN transceiver to realize the wake-up of the controller by the PN request, reducing the project implementation cost.
