Embodiments of the present disclosure may relate to a user's data, the acquisition and/or use of data, and/or the like. These aspects are in accordance with the relevant legal and legal regulations. In the embodiment of the present disclosure, all data collection, acquisition, processing, forwarding, usage, etc. are performed under the premise that the user knows and confirms. Accordingly, in implementing the embodiments of the present disclosure, the user should be informed of the type, usage scope, usage scenario, etc. of the data or information that may be involved and authorized by the user in a suitable manner according to the relevant laws and regulations. The particular manner of notification and/or authorization may vary depending on the circumstances and the application scenario, and the scope of the present disclosure is not limited in this respect.

It will be appreciated that the data referred to in this disclosure, including but not limited to the data itself, the data obtained or used, should comply with applicable legal regulations and related requirements.

As mentioned briefly above, in the smart car, the USB HUB provided by the smart car cabin can be connected to a plurality of external devices at the same time, for example, a certain external device may be a USB flash disk storing music files. When the external equipment is connected with the USB HUB, the intelligent cabin can not read the data of the external equipment or can read errors, so that the function of the external equipment can not be normally realized by the intelligent cabin. For example, music files in the U disk cannot be normally played through the intelligent cockpit. The reasons may be various, for example, in a possible situation, the external device is not detected in the whole process, and whether the external device is normal or not cannot be confirmed. In another possible situation, if the chip of the USB HUB fails due to static electricity or EMC (Electro Magnetic Compatibility), the smart car may also fail to read the data of the external device or read the data incorrectly.

Since the USB HUB may be powered by a power supply, for example, VBAT (Battery voltage). When external device connects USB HUB, the unable data that read external device of intelligence passenger cabin, perhaps when reading the error, common solution is to the power supply outage of USB HUB, then restarts USB HUB, and USB HUB is reset for the data that external device was normally read to the intelligence passenger cabin, perhaps reads correctly. However, the data of the external device normally read by the intelligent cabin cannot be timely recovered by the method, and on the other hand, the power supply of the USB HUB needs to be manually turned off by a user, so that the user experience is poor.

Embodiments of the present disclosure provide a solution for managing USB connection devices. According to various embodiments of the present disclosure, first, a fault associated with a USB connection device (e.g., a USB HUB) is detected by an onboard control device (e.g., a smart cabin). For example, when the USB connected device detects connection of the external device to generate a status message, the in-vehicle control may determine a failure associated with the USB connected device (e.g., USB HUB) based on the status message. Further, when the in-vehicle control apparatus detects a failure associated with the USB connection apparatus, the reset control unit in the USB connection apparatus is activated to generate the reset signal. The reset control unit sends the reset signal to the connection control unit in the USB connection device, so that the connection control unit is reset based on the reset signal, that is, the USB connection device is reset, so that the vehicle-mounted control device can read data of the external device through the USB connection device.

In this way, the in-vehicle control device in the embodiment of the present disclosure generates the reset signal by activating the reset control unit in the USB connection device, which is used by the connection control unit in the USB connection device to reset the USB connection device, instead of directly controlling the connection control unit in the USB connection device by the in-vehicle control device to reset the USB device. On the one hand, the stability of normal work of the USB connection equipment is improved, and the USB connection equipment is recovered to be used under the condition that the user side does not sense the USB connection equipment. On the other hand, the power supply of the USB HUB is turned off without manual operation of a user, so that the operation of the user is reduced, and the user experience is better.

Example USB management System

FIG. 1 illustrates an example USB management system 100 of an embodiment of the present disclosure. As shown in FIG. 1, in the USB management system 100, the USB connection device 110 may be configured to connect the external device 130, and the USB connection device 110 is communicatively connected to the in-vehicle control device 120.

Illustratively, the USB connection device 110 may include, for example, a USB HUB, a USB network converter, a USB audio converter, or the like.

For example, the in-vehicle control device 120 may include a control Chip involved in a smart cabin, an automatic driving, and the like, such as an SoC (System on Chip) or an MCU (micro controller Unit), including but not limited to a display control System, a sound control System, a navigation control System, an air conditioning control System, a voice assistant System, a communication System, a seat control System, an interactive System, a perception System, and the like.

Illustratively, the plurality of external devices 130 are respectively connected to the USB connection device 110, and the external device 130 may be any type of external device, such as a USB disk, a tablet computer, a car recorder, an on-board ETC (Electronic Toll Collection), a media computer, a multimedia tablet, a game device, a wearable device, a Personal Communication System (PCS) device, a personal navigation device, a Personal Digital Assistant (PDA), an audio/video player, a digital camera/camcorder, a positioning device, a television receiver, a radio broadcast receiver, an Electronic book device, or any combination thereof.

In some embodiments, the in-vehicle control device 120 may be configured to detect that a failure associated with the USB connection device 110 occurs when the external device 130 is connected to the USB connection device 110, and to control the USB connection device 110 to reset, that is, to cause the USB connection device 110 to be reset, when a failure associated with the USB connection device 110 is detected.

In some embodiments, further, the USB connection device 110 may include a reset control unit 111 and a connection control unit 112, and the reset control unit 111 and the connection control unit 112 are communicatively connected. The reset control unit 111 may be configured to generate a reset signal for resetting the connection control unit 112 in response to being activated by the in-vehicle control device 120. The connection control unit 112 may be configured to automatically reset based on the received reset signal.

In some embodiments, the reset control unit 111 and the connection control unit 112 are two separate chips integrated inside the USB connection device 110.

Specific procedures for managing universal serial bus USB connected devices are described in further detail below.

Managing USB connected device examples

Fig. 2 shows a schematic diagram of an in-vehicle control device, a reset control unit in a USB connected device, and a connection control unit inter-communication process 200 in which embodiments of the present disclosure can be implemented.

Fig. 3 illustrates a flow diagram of a process 300 for managing a universal serial bus USB connected device according to various embodiments of the disclosure. Process 300 may be implemented by in-vehicle control device 110 as shown in fig. 1.

The process 300 for managing USB connected devices is described in detail below in conjunction with FIG. 2.

As shown in fig. 3, at block 310, a status message from the USB connection device 110 is received by the in-vehicle control device 120, the status message being generated by the USB connection device 110 in response to detecting the connection of the external device 130.

Referring to fig. 2, if the USB connection device 110 detects that the external device 130 is connected to the USB connection device 110, the USB connection device 110 generates a status message and transmits 210 the status message to the in-vehicle control device 120.

In some embodiments, the status message may indicate an operational status of the USB connection device 110. For example, whether the USB connection device 110 is in a state of connecting the in-vehicle control device 120 and the external device 130. After the vehicle-mounted control device 120 receives the status message, the vehicle-mounted control device 120 may detect whether a communication connection is established between the vehicle-mounted control device 120 and the external device 130 based on the check bits of the USB data.

For example, if the status message indicates that the USB connection device 110 is not in a state of connecting the vehicle control device 120 and the external device 130, the vehicle control device 120 detects that no communication connection is established between the vehicle control device 120 and the external device 130 based on the check bits of the USB data.

For example, if the status message indicates that the USB connection device 110 is in a state of connecting the in-vehicle control device 120 and the external device 130. It is detected by the in-vehicle control apparatus 120 that a communication connection is established between the in-vehicle control apparatus 120 and the external apparatus 130 based on the check bits of the USB data.

In some embodiments, the status message may also indicate the identity of the external device 130. For example, the status message may indicate that an identifier of the external device 130, such as an Identifier (ID) of the external device 130, can be detected, and different types of external devices correspond to different IDs. Alternatively, the status message may indicate that the identification of the external device 130 is detected to be correct.

For example, the status message may indicate, for example, that the ID of the external device 130 cannot be detected or that an identification error of the external device 130 is detected.

At block 320, a determination is made by in-vehicle control device 120 that a fault associated with USB connected device 110 has occurred based on the status message.

In some embodiments, one possible failure situation, the in-vehicle control apparatus 120 determines that the USB connection apparatus 110 itself has failed based on the operation state of the USB connection apparatus 110 indicated in the status message. For example, in a case that the status message received by the vehicle-mounted control device 120 indicates that the USB connection device 110 is not in a state of connecting the vehicle-mounted control device 120 and the external device 130, that is, the vehicle-mounted control device 120 and the external device 130 do not establish communication connection, it is determined that the USB connection device 110 has a fault, and the vehicle-mounted control device 120 cannot read data of the external device 130 through the USB connection device 110.

For example, the reason why the in-vehicle control device 120 is not successfully connected to the external device 130 may be various reasons, for example, the USB interface of the external device 130 is damaged, or the USB interface of the USB connection device is damaged.

In some embodiments, in another possible failure scenario, in-vehicle control device 120 determines that external device 110 failed to recognize based on the identification of external device 110 indicated in the status message. For example, the status message may indicate that the ID of the external device 130 cannot be detected or that the identification of the external device 130 is incorrect, and it is determined that the external device 110 fails to recognize, so that the vehicle-mounted control device 120 cannot read the data of the external device 130.

In block 330, the reset control unit 111 in the USB connection device 110 is activated by the in-vehicle control device 120 to generate the reset signal 240 for resetting the connection control unit 112 in the USB connection device 110.

As discussed with reference to fig. 1, after the in-vehicle control device 120 detects a fault associated with the USB connected device, an activation signal may be sent 230 to the USB connected device 110 to activate the reset control unit 111, with a reset signal 240 being generated by the activated reset control unit 111.

In some embodiments, the reset control unit 111 and the connection control unit 112 in the USB connection device 110 may be powered by a common power supply for the USB connection device 110. The reset control unit 111 and the connection control unit 112 are always in the power-on state. The reset control unit 111 is not in an operating state until it is not activated, but in an operating state until it is activated, and generates a reset signal 240. The reset signal 240 is used to restart the connection control unit 112, and the connection control unit 112 is automatically reset based on the reset signal 240.

The in-vehicle control device 120 sends the activation signal to activate the reset control unit 111, and different activation modes can be selected according to different failure reasons.

In some embodiments, if the USB connection device 110 itself malfunctions, the reset control unit 111 is activated by the in-vehicle control device 120 through the pin electrical connection with the reset control unit 111, for example, an electrical signal is provided by the in-vehicle control device 120 to a predetermined pin of the reset control unit 111 based on the pin electrical connection to activate the reset control unit 111. The activation signal may be a power supply signal provided by a predetermined pin. For example, the in-vehicle control apparatus 120 provides a predetermined pin USB VBUS to the USB HUB, and the in-vehicle control apparatus 120 transmits a power supply signal through the pin USB VBUS to activate the reset control unit 111. The activation signal may be a power supply signal at this time.

In some embodiments, in the case where the communication connection is established between the in-vehicle control apparatus 120 and the external device 130 if the failure is the recognition failure of the external device 130, the reset control unit 111 is activated by the in-vehicle control apparatus 120 based on the data communication with the USB connection device 110.

Preferably, the vehicle control device 120 may select the data communication of the USB connection device to be activated with priority higher than that activated by supplying power through a predetermined pin, so as to improve the effectiveness of the activation.

In some embodiments, if the USB connected device 110 is automatically reset multiple times, a fault associated with the USB connected device 110 can still be detected by the in-vehicle control device 120, generating a reminder for manual service.

In some embodiments, if the in-vehicle control apparatus 110 determines that a malfunction associated with the USB connection apparatus 110 does not occur based on the status message, the in-vehicle control apparatus 110 may recognize and read data of the external apparatus 130 through the USB connection apparatus 120. For example, the status message received by the in-vehicle control device 120 indicates that the in-vehicle control device 120 successfully detects the ID of the external device 130, or that the detected ID is correct. Alternatively, the status message received by the vehicle-mounted control device 120 indicates that the USB connection device 110 is in a state of connecting the vehicle-mounted control device 120 and the external device 130, that is, the vehicle-mounted control device 120 and the external device 130 are connected in a communication manner.

Illustratively, the USB connection device 110 is a USB HUB, the external device 130 is a USB flash disk, in which music files are stored, and the vehicle-mounted control device 120 is a smart car. After the intelligent cabin is inserted into the USB flash disk through the USB HUB, music in the USB flash disk can be played. After the USB HUB is inserted into the USB flash disk, if the intelligent cockpit detects that the fault associated with the USB flash disk does not occur, the intelligent cockpit plays music in the USB flash disk. However, after the USB HUB is plugged into the USB flash disk, if the intelligent cockpit does not play music immediately, the intelligent cockpit detects a failure associated with the USB flash disk. For example, the USB HUB generates a status message in response to detecting the USB flash disk. The USB HUB sends the status message to the intelligent cockpit, and the intelligent cockpit reports the fault associated with the USB HUB based on the status message. For example, the failure associated with the USB HUB may be a failure of the USB HUB itself, or the failure of the smart car to recognize the USB disk. If USB HUB breaks down, the intelligence passenger cabin sends the signal of telecommunication to USB HUB through predetermined pin, activates the reset control unit among the USB HUB. If the intelligent cockpit cannot recognize the fault of the USB flash disk, the intelligent cockpit activates a reset control unit in the USB HUB through data communication based on the USB HUB. The reset control unit generates a reset signal for resetting the connection control unit in the USB HUB after being activated. The connection control unit is automatically reset based on the reset signal, that is, the USB HUB is reset.
