[0002] Traditional and existing autonomous driving assistance domain control products cannot monitor the surroundings or understand the status of the vehicle after the user parks and locks it. Especially after the driver leaves the vehicle, at a distance, it is impossible to assess the vehicle's condition in its natural environment, and therefore, it is impossible to effectively and quickly trace any abnormalities or damage that may occur.

[0003] Existing technologies typically introduce a "sentinel mode" on top of existing domain control products, using cameras to implement a monitoring mechanism after the vehicle driver leaves.

[0004] However, once the existing car sentry mode is activated, the camera module, vehicle controller, and anti-theft module are all in working condition, which can lead to the risk of the car running out of power if they remain in working condition for an extended period of time. Summary of the Invention

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] Example 1

[0033] Figure 1 This invention provides a structural block diagram of a vehicle monitoring system according to Embodiment 1. This embodiment is applicable to situations where the vehicle is monitored after it has been locked, such as... Figure 1 As shown, the image acquisition module 11 also includes: a switching transistor 12 and a microcontroller 13 that continuously receives power from a power source. Among them,

[0034] When the microcontroller 13 receives the sentinel mode switching signal, it cuts off the power supply from the original sentinel mode power supply circuit to the image acquisition module 11 and sends a conduction signal to the switching transistor 12 so that the microcontroller 13 can supply power to the image acquisition module 11.

[0035] It's important to know that in normal operating mode (such as during driving or reversing), the vehicle typically activates 11 cameras, along with over 20 power supply circuits and processing algorithms. These 11 cameras include 4 surround-view cameras and 7 front, rear, and side-view cameras. The video data from these 11 cameras is then analyzed and displayed by a video analysis circuit. To meet the overall control requirements of the 11 cameras and the analysis requirements of the video analysis circuit, the vehicle usually uses a powerful system-on-a-chip (SoC) for control and is powered by these 20+ power supply circuits, typically using 12V to ensure the normal operation of the 11 cameras. However, in sentry mode, it's not necessary to activate all cameras; only the surround-view cameras are needed to provide comprehensive monitoring of the vehicle's surroundings. These surround-view cameras are typically 4 wide-angle cameras, and by stitching the images from these 4 wide-angle cameras together, a complete panoramic image of the vehicle's surroundings is formed.

[0036] In this embodiment, the sentry mode switching signal can be understood as a signal used to activate the sentry mode. Generally, the sentry mode is activated after the vehicle is locked; that is, after receiving a locking signal via the vehicle key or other means, the locking signal is converted into a sentry mode switching signal. The original sentry mode power supply circuit can be understood as the circuit that supplies power to the camera under normal vehicle operation conditions, i.e., 12V power supply. The switching transistor 12 can be understood as a device used to control the circuit's on / off state, and is preferably a field-effect transistor (MOSFET). The conduction signal can be understood as a signal used to control the conduction of the circuit containing the switching transistor 12, such as a level signal. The image acquisition module 11 can be understood as a camera used for image acquisition in sentry mode, and is preferably a 4-channel surround-view camera.

[0037] Specifically, when the microcontroller 13 receives the sentry mode switching signal, it can cut off the power supply from the original sentry mode power supply circuit to the image acquisition module 11, i.e., the original SOC's 12V power supply circuit, putting the SOC into a sleep state. The microcontroller 13 can send a conduction signal to the switching transistor 12 through the level pin. Since the microcontroller 13 is still receiving power after the vehicle enters sentry mode, i.e., the power supply of the microcontroller 13 is a constant power supply, such as a 3.3V constant power supply, the circuit between the power supply of the microcontroller 13 and the image acquisition module 11 can be turned on through the switching transistor 12, so that the 3.3V constant power supply of the microcontroller 13 can supply power to the image acquisition module 11. This allows only 4 of the 11 cameras in the vehicle to be turned on, while the other 7 cameras are in a sleep state, so that the 3.3V operating voltage can drive the image acquisition module 11 to work.

[0038] The technical solution of this invention, through an image acquisition module, a switching transistor, and a microcontroller continuously receiving power supply in a vehicle monitoring system, allows the microcontroller to cut off the power supply from the original sentry mode power supply circuit to the image acquisition module upon receiving a sentry mode switching signal. It then sends a conduction signal to the switching transistor, enabling the microcontroller to supply power to the image acquisition module. By cutting off the original high-voltage power supply circuit for all cameras in sentry mode, and having the microcontroller send a conduction signal to the switching transistor, the microcontroller's constant power supply provides power to the image acquisition module (including some cameras) at a lower voltage, and the microcontroller takes over control. This achieves monitoring of the vehicle's surroundings after separation of the vehicle and pedestrian, reduces power consumption and energy usage in sentry mode, avoids the possibility of the car running out of power during prolonged periods in sentry mode, and improves the user experience.

[0039] Optionally, based on the above embodiments, the system further includes: an image processing module connected to the image acquisition module 11; the image processing module is powered by the microcontroller 13 and generates a clock signal through the enable signal of the microcontroller 13, so as to control the image acquisition module 11 to perform image acquisition through the clock signal.

[0040] In this embodiment, the enable signal can be understood as a signal that controls the operation of the image acquisition module 11.

[0041] Specifically, the image processing module can be connected to the image acquisition module 11. The image processing module is powered by the microcontroller 13. The microcontroller 13 can generate an enable signal in the form of a set acquisition frequency, etc., and transmit the enable signal to the image processing module through the enable pin of the microcontroller 13. The image processing module may include a deserializer so that when the image processing module receives the enable signal, it converts the enable signal into a clock signal (i.e., a C-PHY signal) through the deserializer. The clock signal is then transmitted to the image acquisition module 11 through the image processing module so as to control the image acquisition module 11 to perform image acquisition.

[0042] For example, in normal operating mode, the enable signal is sent to the image processing module through the enable pin of the SOC. However, in sentry mode, the SOC is in a sleep state and is controlled by the MCU. Therefore, several diodes need to be added to the original image processing module. The diodes are connected to the enable pin of the MCU to complete the transmission of the enable signal so that the MCU can take over the image processing module.

[0043] Optionally, the system further includes: a first signal switching switch, which is connected to the microcontroller 13 and the image processing module respectively, and is used to convert the first signal input to the microcontroller 13 into a first readable signal of the image processing module.

[0044] It is important to know that in normal operating mode, signals are transmitted directly to the image processing module via the SOC. However, in sentry mode, the MCU takes over and transmits signals to the image processing module. This requires switching the transmission channel. When switching back to normal operating mode, the first signal switching switch switches the transmission channel back to the SOC so that the image processing module is controlled by the SOC in normal operating mode.

[0045] In this embodiment, the first signal switching switch can be understood as a switching device used for data format conversion, such as an IIC switching switch. The first signal can be understood as a control signal under the communication protocol corresponding to the microcontroller 13 sent by the microcontroller 13. The first readable signal can be understood as a signal under the communication protocol that the image processing module can read.

[0046] Specifically, the system also includes a first signal switching switch, which is connected to the microcontroller 13 and the image processing module respectively. In sentry mode, the first signal switching switch can open the connection channel between the microcontroller 13 and the image processing module to enable bidirectional signal transmission. It is also used to convert the first signal input to the microcontroller 13 into a first readable signal of the image processing module and to convert the signal of the image processing module into a readable signal of the microcontroller 13. In normal working mode, the first signal switching switch can also open the connection channel between the original SOC and the image processing module through preset logic and close the connection channel between the microcontroller 13 and the image processing module, so that the image processing module can be controlled by the SOC in normal working mode.

[0047] Optionally, the system further includes a display processing module, wherein the image processing module is powered by the microcontroller 13.

[0048] It is important to know that when the driver wants to rest in the cockpit, the entire vehicle may be locked for safety reasons. When the driver is in the cockpit, he can view the monitoring situation on the local DHU+ display screen. In order to process the image signal acquired by the image acquisition module 11 into a form that can be displayed on the screen, the image processing module needs to work with the image acquisition module 11 to perform image processing. Since the image acquisition module 11 only activates four surround view cameras, the image processing module only needs to process the four surround view cameras with the corresponding algorithm.

[0049] Specifically, when the SOC is in sleep mode, the microcontroller 13 can supply power to the display processing module and take over the display processing module.

[0050] For example, in normal operating mode, the enable signal is sent to the display processing module via the enable pin of the SOC. However, in sentry mode, the SOC is in a sleep state and is controlled by the MCU. Therefore, several diodes need to be added to the original display processing module. The diodes are connected to the enable pin of the MCU to complete the transmission of the enable signal, so that the MCU can take over the display processing module. In normal operating mode, the enable signal can also be sent to the display processing module via the enable pin of the SOC, thus completing the separate takeover of the SOC and the MCU in different modes.

[0051] Optionally, the system further includes: a second signal switching switch, which is connected to the microcontroller 13 and the display processing module, and is used to convert the second signal input to the microcontroller 13 into a second readable signal of the image processing module.

[0052] It is important to know that in normal operating mode, signals are directly transmitted to the display processing module via the SOC. However, in sentry mode, the MCU takes over and transmits signals to the display processing module. At this time, the transmission channel needs to be switched. When switching back to normal operating mode, the transmission channel is switched back to the SOC via the first signal switching switch so that the display processing module is controlled by the SOC in normal operating mode.

[0053] In this embodiment, the second signal switching switch can be understood as a switching device used for data format conversion, such as an IIC switching switch. The second signal can be understood as a control signal under the communication protocol corresponding to the microcontroller 13 sent by the microcontroller 13. The second readable signal can be understood as a signal under the communication protocol that the display processing module can read.

[0054] Specifically, the system also includes a second signal switching switch, which is connected to both the microcontroller 13 and the display processing module. In sentry mode, the second signal switching switch can open the connection channel between the microcontroller 13 and the display processing module to enable bidirectional signal transmission. It also converts the second signal input to the microcontroller 13 into a second readable signal for the display processing module, thus converting the signal from the display processing module into a signal readable by the microcontroller 13. In normal operating mode, the second signal switching switch can also, through preset logic, open the connection channel between the original SOC and the display processing module and close the connection channel between the microcontroller 13 and the display processing module, allowing the display processing module to be controlled by the SOC in normal operating mode. The microcontroller 13 can also upload the monitored video data to a server via an Ethernet link, allowing users to access the video content via mobile phones and PCs.

[0055] The technical solution of this invention, through an image acquisition module, a switching transistor, and a microcontroller continuously receiving power supply in a vehicle monitoring system, allows the microcontroller to cut off the power supply from the original sentry mode power supply circuit to the image acquisition module upon receiving a sentry mode switching signal. It then sends a conduction signal to the switching transistor to allow the microcontroller to supply power to the image acquisition module. By cutting off the original high-voltage power supply circuit for all cameras in sentry mode, and having the microcontroller send a conduction signal to the switching transistor, the microcontroller's constant power supply provides a low voltage to the image acquisition module, which includes some cameras. Furthermore, the microcontroller takes over control of the image processing module and the display processing module through two signal switching switches. This achieves switching between control subjects in different modes, enables monitoring of the vehicle's surroundings after separation of the vehicle and its driver, reduces power consumption and energy usage in sentry mode, avoids the possibility of the car running out of power during prolonged periods in sentry mode, and improves the user experience.

[0056] For example, to facilitate understanding of the vehicle monitoring system provided by this invention, it is illustrated through two parts: a power control section and a signal control section. Figure 2 This is a power control diagram of a vehicle monitoring system according to Embodiment 1 of the present invention, as shown below. Figure 2As shown, the system includes: a constant power supply circuit 21, a microcontroller 22, a switching transistor 23, a primary sentry mode power supply circuit 24, an image acquisition module 25, an image processing module 26, and a display processing module 27. When the microcontroller 22 receives a sentry mode switching signal, it cuts off the power supply from the primary sentry mode power supply circuit 24 to the image acquisition module 25. Instead, it sends an enable signal to the switching transistor 23 via the GPIO pin of the microcontroller 22, thus enabling the microcontroller 22 to supply power to the image acquisition module 25. The image processing module 26 may include a deserializer, a diode, and a power supply chip. The image processing module 26 can be connected to the image acquisition module 25. The microcontroller 22 supplies power to the image processing module 26, and the enable pin of the microcontroller 22 controls the diode to transmit an enable signal to the image processing module 26. The image processing module 26 then transmits a clock signal to the image acquisition module 25. The display processing module 27 may include a serializer, a diode, and a power supply chip. The microcontroller 22 supplies power to the display processing module 27, and the enable pin of the microcontroller 22 controls the diode to transmit an enable signal to the display processing module 27.

[0057] For example, a system-on-a-chip (SoC) is typically used as the control chip for the vehicle in normal operating mode. Figure 3 This is a signal control diagram of a vehicle monitoring system according to Embodiment 1 of the present invention, as shown below. Figure 3 As shown, the system includes a microcontroller 31, a first signal switching switch 32, an image processing module 33, a second signal switching switch 34, a display processing module 35, and a system-on-a-chip (SoC) 36. In normal operation mode, the first signal switching switch 32 only connects the SoC 36 to the image processing module 33, and the second signal switching switch 34 only connects the SoC 36 to the display processing module 35. An enable signal is sent to both the image processing module 33 and the display processing module 35 via the enable pin of the SoC 36. However, in sentry mode, the SOC is in sleep mode and controlled by the MCU. In sentry mode, the first signal switching switch 32 only connects the microcontroller 31 to the image processing module 33, and the second signal switching switch 34 only connects the microcontroller 31 to the display processing module 35. An enable signal is sent to both the microcontroller 31 to the image processing module 33 and the display processing module 35 via the enable pin of the microcontroller 31, thus enabling switching between controller modes.

This method can be executed by a vehicle monitoring system, which can be implemented in hardware and / or software and can be configured in a vehicle. Figure 4 As shown, the method includes:

[0060] S110. Upon receiving the sentry mode switching signal, the power supply from the original sentry mode power supply circuit to the image acquisition module is cut off, and a conduction signal is sent to the switching transistor to supply power to the image acquisition module.

[0061] S120: Send a turn-on signal to the switching transistor to supply power to the image acquisition module.

[0062] The technical solution of this invention, through an image acquisition module, a switching transistor, and a microcontroller continuously receiving power supply in a vehicle monitoring system, allows the microcontroller to cut off the power supply from the original sentry mode power supply circuit to the image acquisition module upon receiving a sentry mode switching signal. It then sends a conduction signal to the switching transistor, enabling the microcontroller to supply power to the image acquisition module. By cutting off the original high-voltage power supply circuit for all cameras in sentry mode, and having the microcontroller send a conduction signal to the switching transistor, the microcontroller's constant power supply provides power to the image acquisition module (including some cameras) at a lower voltage, and the microcontroller takes over control. This achieves monitoring of the vehicle's surroundings after separation of the vehicle and pedestrian, reduces power consumption and energy usage in sentry mode, avoids the possibility of the car running out of power during prolonged periods in sentry mode, and improves the user experience.

[0063] Optionally, the method further includes:
