Description
Technical Field
[0001] This application relates to the field of computer technology, and more specifically, to a timeout feedback method, apparatus, medium, and electronic device using a vehicle infotainment bus. Background Technology
[0002] Most modern cars use the CAN bus as their control bus. Based on the CAN bus, controllers, sensors, actuators, and other components on the vehicle are connected through a common bus. Any device on the bus can communicate with other devices on the bus in real time.
[0003] With the increasing functionality of automotive controllers today, the settings applications on car infotainment screens also include many vehicle control-related settings, such as turning cruise control on / off and ambient lighting on / off. Therefore, these applications need to communicate with the CAN bus, sending commands to the corresponding controllers and listening for feedback from the CAN bus. However, due to various issues such as incorrect signal IDs, communication errors, or controller malfunctions, feedback may not be received after the application sends commands. Existing solutions often handle individual exceptions separately, and when such situations occur during development, they cannot quickly locate the problem, resulting in high code reusability and cumbersome troubleshooting.

[0014] Optionally, the method further includes:
[0015] When the automatic setting method in the setting class is called to perform a bounce operation based on the current setting information of any of the controlled objects, if the debugging flag meets the preset opening conditions, the current setting information and the target setting information are displayed.

[0022] The removal unit is used to call the passive setting method in the setting class to remove the timeout message from the message queue when the automatic setting method stores the timeout message sent to the handle into the message queue after the timeout duration is limited.
[0023] Optionally, the device further includes:
[0024] A storage unit is used to save the current setting information of any control object when the target setting information of any control object is obtained;

If the automatic setting method stores a timeout message in the message queue, and the VMS bus issues a delayed feedback signal, indicating a problem with both the VMS bus and the settings, then the passive setting method in the setting class is invoked to remove the timeout message from the message queue. This prevents the handle from receiving a timeout message and responding accordingly, thus ensuring that the execution unit retains its original settings and that the VMS execution unit can execute under safe settings.

[0042] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.
[0043] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.
[0044] The embodiments provided in this application are embodiments of a timeout feedback method using a vehicle-mounted bus.
[0045] The following is combined with Figure 1 The embodiments of this application will be described in detail.
[0046] Step S101: In response to receiving trigger information from any controllable object in the vehicle system, obtain the target setting information of the controllable object.
[0047] The target setting information refers to the information that any controlled object prepares to set for the execution unit of the vehicle system. The target setting information needs to be set before triggering any controlled object. For example, before adjusting the vehicle's air conditioning, the target setting information needs to be filled in beforehand. Then, an adjustment signal is sent to the vehicle's air conditioning via the setting button. After receiving the setting signal, the vehicle's air conditioning adjusts itself according to the target setting information.
[0048] Step S102: Invoke the automatic setting method in the setting class related to the control object in the vehicle system to set the target settings information of any control object.
[0049] The settings class inherits from a public class, which includes at least: handles for sending, receiving, and processing messages, timeout messages and timeout durations, as well as automatic and passive settings methods implemented through the vehicle bus.
[0050] Handler is a message communication mechanism in Android used for communication between child threads and the main thread, implementing a non-blocking message passing mechanism.
[0051] In this embodiment of the application, the Handler is used to send, receive, and process messages.
[0052] The public class listens for and waits for messages through the `handleMessage` method; it also provides a delay for sending messages using `handler.sendEmptyMessageDelayed` in the automatic setup method. When the vehicle bus (such as the CAN bus) provides normal feedback, the `removeMessage` method in the passive setup method removes the message.
[0053] In Android system development, the class that inherits from is called the subclass, and the class that is inherited from is called the parent class. After inheritance, the subclass automatically inherits the attributes and methods of the parent class.
[0054] In this embodiment, the designed public class serves as the parent class for all setting classes. Therefore, all setting classes inherit the Handler and methods from the public class, automatically implementing the functionality of the public class.
[0055] A Controller Area Network (CAN bus) is a serial communication network that enables distributed real-time control. It typically consists of three parts: a CAN transceiver, a CAN controller, and an MCU. The CAN bus transmits data via differential signals. The CAN transceiver converts the differential signals to TTL level signals, or vice versa. The CAN controller receives the TTL level signals and transmits them to the MCU.
[0056] The settings class transmits settings information to the execution system via the vehicle's infotainment bus.
[0057] Automatic setup methods are used at least to configure the execution units in the vehicle system via the vehicle bus. For example, the loading method.
[0058] Passive setter methods are used to clear timed-out messages from the message queue at least under preset clearing conditions. For example, the `loaded` method.
[0059] Step S103: When it is determined that a delayed feedback signal for any of the controlled objects is received from the vehicle bus, the passive setting method in the setting class is invoked to monitor the message queue.
[0060] Typically, when the automatic setup method of the settings class performs settings via the vehicle's infotainment system (V2S), a delayed feedback signal from the V2S indicates poor communication and unsuccessful setup. Furthermore, the delayed feedback signal is received within the timeout period, specifically before the timeout message is received. At this point, the passive setup method in the settings class is invoked to monitor the message queue.
[0061] Step S104: When the automatic setting method stores the timeout message sent to the handle into the message queue after the timeout duration is limited, the passive setting method in the setting class is called to remove the timeout message from the message queue.
[0062] This application embodiment monitors whether there are timeout messages in the message queue by calling the passive setting method of the setting class. When a timeout message appears in the message queue, the timeout message is removed from the message queue to prevent the handle from receiving the timeout message and making a corresponding response, so that the execution unit still maintains the original settings.
[0063] In some other specific embodiments, the method further includes the following steps:
[0064] Step S101a: When the target setting information of any of the controlled objects is obtained, the current setting information of any of the controlled objects is also saved.
[0065] The current settings information refers to the settings that the control object is currently executing on the vehicle system's execution unit.
[0066] For example, continuing with the example above, before adjusting the vehicle's air conditioning, save the settings information that the vehicle's air conditioning is currently performing.
[0067] Step S105: When the handle obtains a timeout message from the message queue, the automatic setting method in the setting class is called to perform a bounce operation based on the current setting information of any of the control objects.
[0068] The fact that the handle obtains a timeout message from the message queue can be understood as the absence of a delay feedback signal from the vehicle bus for any of the controlled objects, indicating that the vehicle bus communication is normal and the passive setting method in the setting class is not called to monitor the message queue. Therefore, the timeout message stored by calling the automatic setting method will not be removed from the message queue, thus enabling the handle to obtain the timeout message from the message queue.
[0069] The timeout message at this time is generated by the automatic setting method, not due to a fault in the vehicle bus. Therefore, the automatic setting method may affect the settings of the execution unit. To address this, this specific embodiment provides a method to call the automatic setting method in the setting class to perform a bounce operation based on the current setting information of any of the control objects, ensuring that the execution unit can execute under the correct settings.
[0070] In some specific embodiments, the method further includes the following steps:
[0071] When the automatic setting method in the setting class is called to perform a bounce operation based on the current setting information of any of the controlled objects, if the debugging flag meets the preset opening conditions, the current setting information and the target setting information are displayed.
[0072] This specific embodiment also provides a debugging indicator. When performing a bounce operation, if the debugging indicator meets preset activation conditions, it displays the current setting information and the target setting information, so that technicians can promptly identify errors caused by specific settings. Optionally, the current setting information and the target setting information are saved in a debugging log so that technicians can backtrack on errors caused by specific settings.
[0073] Optionally, the target setting information includes at least the control object identifier of any of the control objects. This helps technicians locate the control object.
[0074] Optionally, the current setting information includes at least the class number and class name of the setting class related to any of the manipulated objects. This helps technicians locate the relevant setting class.
[0075] This application provides a timeout feedback method for using a vehicle-mounted bus. When any control object in the vehicle-mounted system is triggered, the automatic setting method in the settings class related to the control object in the vehicle-mounted system is called to set the execution unit via the vehicle-mounted bus. If the automatic setting method stores a timeout message in the message queue, and the vehicle-mounted bus issues a delayed feedback signal, indicating that both the vehicle-mounted bus and the settings have problems, then the passive setting method in the settings class is called to remove the timeout message from the message queue. This is to prevent the handle from receiving a timeout message and responding accordingly, thereby ensuring that the execution unit retains its original settings and that the vehicle-mounted system's execution unit can execute under safe settings.
[0076] This application also provides an apparatus embodiment that follows the above embodiments, used to implement the method steps described in the above embodiments. The interpretation of the same names is the same as that in the above embodiments, and the same technical effects are achieved. Therefore, it will not be repeated here.

[0080] The monitoring unit 203 is used to call the passive setting method in the setting class to monitor the message queue when it is determined that a delayed feedback signal for any controlled object is received from the vehicle bus.
[0081] The removal unit 204 is used to call the passive setting method in the setting class to remove the timeout message from the message queue when the automatic setting method stores the timeout message sent to the handle into the message queue after the timeout duration is limited.

If the automatic setting method stores a timeout message in the message queue, and the vehicle-mounted bus issues a delayed feedback signal, indicating a problem with both the vehicle-mounted bus and the settings, then the passive setting method in the settings class is called to remove the timeout message from the message queue. This prevents the handle from receiving a timeout message and responding accordingly, thus ensuring that the execution unit retains its original settings and that the vehicle-mounted system's execution unit can execute under safe settings.
