[0028] like Figure 1 As shown, the system architecture 100 may include a vehicle device 101 and an external device 102. The vehicle device 101 may include: a processor, a controller, an input / output port, and a universal serial bus module.

[0030] It should be understood that Figure 1 The number of vehicle-mounted devices and external devices in the embodiment is only for illustration. Any number of vehicle-mounted devices and external devices may be provided according to implementation requirements.

[0031] Please refer to Figure 2 , Figure 2 This is a flowchart of an exception handling method provided by an embodiment of the present disclosure, wherein process 200 includes the following steps:

[0032] Step 201: In response to determining that an abnormality occurs in a function operation based on a universal serial bus module, a processor of the vehicle device generates a serial port message instructing the universal serial bus module to be powered off and then powered on, and sends the serial port message to a controller of the vehicle device.

[0033] Exemplarily, the processor may be a microprocessor unit (MPU), etc., and the controller may be a microcontroller unit (MCU), etc. A universal serial bus (USB) module is configured in the vehicle device.

[0034] Exemplarily, the operation may include configuring memory space and / or data transmission. The abnormality of the functional operation may be an error or failure in configuring the memory space, or an error or failure in data transmission.

[0035] In this embodiment, the processor of the vehicle device detects an abnormality when configuring memory space for the universal serial bus module, or detects an abnormality in data transmission through the universal serial bus module, generates a serial port message, and the serial port message is used to instruct the universal serial bus module to be powered off and then powered on, and sends the serial port message to the controller of the vehicle device to instruct the controller to control the universal serial bus module to be powered off and then powered on, so as to realize hardware power-on. The processor and the controller can communicate with each other through the serial port protocol.

[0036] Optionally, the serial port message can be encapsulated into an interface function, which is called after the failure of the function related to the universal serial bus module. For example, a bit of 0 in the interface function indicates that the universal serial bus module is powered off, and a bit of 1 in the interface function indicates that the universal serial bus module is powered on, which is only an example.

[0037] Step 202: The controller of the vehicle machine device controls the universal serial bus module to be powered off and then powered on through the input and output ports based on the serial port message.

[0038] Exemplarily, the input / output port may be a general purpose input / output (GPIO) interface, and the controller of the vehicle machine device controls the power supply of the corresponding module through the input / output port, and the module includes a universal serial bus module.

[0039] In this embodiment, after receiving the serial port message, the controller of the vehicle-mounted device switches the state of the input / output port that powers the universal serial bus module. For example, after lowering the level of the input / output port that powers the universal serial bus module, the level of the input / output port that powers the universal serial bus module is raised, thereby controlling the universal serial bus module to be powered off and then powered on.

[0040] If the universal serial bus module is controlled to connect to an external device, simulated hot plugging of the external device (such as a camera, etc.) connected to the universal serial bus module can be achieved, without the need for the user to manually plug and unplug the external device, thereby improving the user experience.

[0041] Step 203: In response to determining that the universal serial bus module is powered off and then powered on and the functional operation is to configure the memory space, the processor of the vehicle device configures the memory space again.

[0042] After an exception occurs in the configuration memory space, it is determined that the universal serial bus module is powered on again and the memory space is configured again so that the functions of the universal serial bus module can be used normally without the user having to query the abnormal problem, thereby improving the vehicle computer functions and enhancing the user experience.

[0043] Step 204: In response to determining that the universal serial bus module is powered off and then powered on and the functional operation is data transmission, the processor of the vehicle device continues data transmission based on the record information associated with the data transmission.

[0044] Exemplarily, the recorded information includes, but is not limited to, one or more of the following: the time of failure of data transmission, the content of the transmitted data, the amount of data transmitted, and the transmission rate.

[0045] When data transmission is abnormal, the USB module is powered on again, and the external device connected to the USB module can be actively reconnected and mounted, and then data transmission can continue based on the recorded information associated with data transmission, such as continuing to play videos, so as to avoid users discovering device abnormalities and raising questions, and reduce the sense of disconnection for users. Users do not need to be distracted by plugging and unplugging devices, which can improve driving safety.

[0046] The exception handling method provided by the embodiment of the present disclosure, in response to determining that an exception occurs in a functional operation based on a universal serial bus module, controls the universal serial bus module to power off and then power on through an input and output port, actively powers on the hardware, and then continues to perform the functional operation. The user does not need to find and resolve the exception, which can improve the user experience.

[0047] Please refer to Figure 3 , Figure 3 A flowchart of another exception handling method provided by an embodiment of the present disclosure, wherein process 300 includes the following steps:

[0048] Step 301: In response to obtaining a power-on operation or a wake-up operation, the processor of the vehicle device initializes the universal serial bus module, configures the memory space, and detects whether an abnormality occurs in the configured memory space.

[0049] For example, the processor of the vehicle equipment can use the port function hub_port_connect to initialize the universal serial bus module, wait for the external device to connect to the universal serial bus module, and use the configuration space structure function usb_alloc_dev to configure the memory space.

[0050] For example, during the initialization of the USB module, an error or failure occurs when allocating space resources for the USB module.

[0051] Step 302: In response to determining that an abnormality occurs in the configuration memory space based on the USB module, the processor of the vehicle device generates a serial port message instructing the USB module to be powered off and then powered on, and sends the serial port message to the controller of the vehicle device.

[0052] Step 303: The controller of the vehicle machine device controls the universal serial bus module to be powered off and then powered on through the input and output ports based on the serial port message.

[0053] Optionally, the controller of the vehicle device can control the universal serial bus module through the input and output ports to power off and then power on based on the serial port message after a period of time (for example, a delay of 200ms after determining that an abnormality has occurred), for example, to re-power external devices.

[0054] The specific implementation of the above steps 302 and 303 can refer to the above steps 201 and 202, which will not be repeated here.

[0055] Step 304: In response to determining that the USB module is powered off and then powered on, the processor of the vehicle device initializes the USB module again and configures the memory space again.

[0056] The processor of the vehicle-mounted device responds to determining that the universal serial bus module is powered off and then powered on, and executes the port function hub_port_connect again to initialize the universal serial bus module, and executes the configuration space structure function usb_alloc_dev again to configure the memory space, which can solve the impact of occasional problems on user experience and improve the code logic.

[0057] Optionally, after the hub_port_connect function enters the error repair process, the processor of the vehicle device can also generate a serial port message to instruct the universal serial bus module to power off and then power on. After the universal serial bus module is powered on again, the port function hub_port_connect is executed again to initialize the universal serial bus module, which can improve the vehicle function and enhance the user experience.

[0058] In the exception handling method provided by the embodiment of the present disclosure, the processor of the vehicle-mounted device initializes the universal serial bus module and configures the memory space. After an exception occurs in the configuration of the memory space, a serial port message is sent to the controller of the vehicle-mounted device. The controller controls the universal serial bus module to power off and then power on through the input and output ports based on the serial port message. The processor of the vehicle-mounted device initializes the universal serial bus module and configures the memory space. After an exception occurs in the configuration of the memory space, the user does not need to query the exception problem, and the external device identification or terminal device charging can continue, etc., thereby improving the vehicle-mounted function and enhancing the user experience.

[0059] Please refer to Figure 4 , Figure 4 A flowchart of another exception handling method provided by an embodiment of the present disclosure, wherein process 400 includes the following steps:

[0060] Step 401: In response to determining that data transmission based on the universal serial bus module is abnormal, the processor of the vehicle-mounted device generates a serial port message instructing the universal serial bus module to be powered off and then powered on, sends the serial port message to the controller of the vehicle-mounted device, obtains an application associated with the data transmission, and obtains record information based on the memory mode of the application.

[0061] Optionally, the method provided by the embodiment of the present disclosure may further include: the processor of the vehicle device determines whether an abnormality occurs in the data transmission based on the universal serial bus module. For example, the processor of the vehicle device receives an error message from the universal serial bus module indicating that an abnormality occurs in the data transmission based on the universal serial bus module, and determines that an abnormality occurs in the data transmission based on the universal serial bus module according to the error message.

[0062] Optionally, the data transmission anomaly may be caused by an external device or by a vehicle-mounted device, which is not limited in the present disclosure.

[0063] Optionally, the error message may include information related to the data transmission, such as an application identifier associated with the data transmission. The processor of the vehicle device obtains the application associated with the data transmission according to the application identifier associated with the data transmission, and obtains the record information based on the memory mode of the application.

[0064] The embodiment of the present disclosure does not limit the execution order of generating the serial port message and obtaining the record information. The serial port message can be generated first and then the record information can be obtained, or the record information can be obtained first and then the serial port message can be generated.

[0065] In some embodiments, the method provided by the embodiment of the present disclosure may further include: after receiving the error message, the processor of the vehicle device deletes the sector data and stops the data transmission. After receiving the error message indicating that the data transmission is abnormal, the processor of the vehicle device releases resources, clears the sector data, and stops the data transmission. The embodiment of the present disclosure does not limit the execution order of deleting the sector data, generating the serial port message, and obtaining the record information.

[0066] Step 402: The controller of the vehicle machine device controls the universal serial bus module to be powered off and then powered on through the input and output ports based on the serial port message.

[0067] Step 403: In response to determining that the universal serial bus module is powered off and then powered on, the processor of the vehicle device continues to perform data transmission based on the recorded information associated with the data transmission.

[0068] The specific implementation of the above steps 402 and 403 can refer to the above steps 202 and 204, which will not be repeated here.

[0069] The method provided by the embodiment of the present disclosure determines that an abnormality has occurred in data transmission based on a universal serial bus module, obtains data transmission related record information, controls the universal serial bus module to power off and then power on, and continues data transmission based on the record information, thereby reducing the user's sense of disconnection.

[0070] To deepen understanding, the present disclosure also provides specific implementation solutions in combination with specific application scenarios.

[0071] Take the electrical connection between a USB flash drive and a universal serial bus module of a vehicle-mounted device as an example. In response to obtaining a power-on operation or a wake-up operation, the MPU of the vehicle-mounted device uses the port function hub_port_connect to initialize the universal serial bus module, uses the configuration space structure function usb_alloc_dev to configure the memory space, and detects whether an abnormality occurs in the configuration memory space.

[0072] When the MPU detects that there is no abnormality in the configuration memory space and detects the operation of playing music in the USB flash drive, the USB flash drive sends the music data to the vehicle-mounted device through the universal serial bus module, and the vehicle-mounted device receives the music data and plays the music.

[0073] If the MPU detects that an abnormality has occurred in the configuration memory space, it generates a serial port message instructing the universal serial bus module to be powered off and then powered on, and sends the serial port message to the MCU of the vehicle device. Based on the serial port message, the MCU controls the universal serial bus module to be powered off and then powered on through GPIO, which can realize simulated hot plugging of the USB flash drive (if the USB flash drive is already connected) that is electrically connected to the universal serial bus module, without the need for the user to manually plug in and out the USB flash drive. In response to determining that the universal serial bus module has been powered off and then powered on, the MPU initializes the universal serial bus module again, configures the memory space again, and detects whether an abnormality has occurred in the configuration memory space. If an abnormality has been detected in the configuration memory space again, the above steps can be repeated. If the MPU detects that the configuration memory space is normal, the vehicle device and the USB flash drive can interact and transmit data based on the user's playback operation, such as playing music.

[0074] When the U disk interacts with the vehicle-mounted device through the universal serial bus module and the vehicle-mounted device plays music through the music reference, the MPU can detect whether there is an abnormality in the data transmission based on the universal serial bus module. If an abnormality occurs, a serial port message is generated and sent to the MCU. The record information can also be obtained based on the memory mode of the music application. The record information can record the abnormal time, the content of the transmitted music data, the amount of data transmitted, etc. After receiving the serial port message, the MCU controls the universal serial bus module to power off and then power on through GPIO to reconnect the U disk, without the user manually unplugging and plugging the U disk. In response to determining that the universal serial bus module has been powered off and then powered on, the MPU continues to play music based on the recorded information. The reconnected U disk continues to send music data to the vehicle-mounted device, which can reduce the sense of disconnection for users.

The sending module 502 is configured to control the universal serial bus module to be powered off and then powered on based on the serial port message and the input and output ports through the controller.

The transmission module 504 is configured to continue data transmission based on the record information associated with the data transmission in response to determining that the universal serial bus module is powered off and then powered on and the functional operation is data transmission through the processor.
