[0064] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0065] Figure 1 is a step flow chart of a vehicle hibernation monitoring method provided by an embodiment of the present application, as shown in Figure 1 the method is applied to an intelligent high-side chip, the intelligent high-side chip is integrated with a current detection circuit, the intelligent high-side chip is connected with an external monitoring module, and can include:

[0066] It should be noted that, as shown in Figure 5 , Figure 5 is a schematic diagram of a vehicle hibernation monitoring system in an exemplary vehicle hibernation monitoring method, the system is composed of a vehicle end, a cloud end and a user end, the present application is mainly applied to an intelligent high-side chip, the intelligent high-side chip is integrated with a current detection circuit, and the intelligent high-side chip is connected with an external monitoring module.

[0067] Specifically, the intelligent high-side chip usually integrates current detection, protection and control functions. It can monitor the current flowing through the load in real time, and take appropriate protective measures when detecting that the current exceeds the preset threshold. The intelligent high-side chip measures the current flowing through the load through an internal current detection circuit. This circuit usually includes a small resistance (called a detection resistance or shunt resistance), and a voltage drop proportional to the current is generated when the current flows through the resistance. The ADC (Analog-to-Digital Converter) inside the chip converts this voltage into a digital signal, and then determines whether the current exceeds the threshold through an internal comparator or microcontroller.

[0068] Step 101, in the case of detecting that the body domain controller is in a sleep state and the first target pin corresponding to the intelligent high-side chip is in a preset level state, start the low-power mode;

[0069] It should be noted that in the embodiments of the present application, when the body domain controller is powered off after sleeping, the MCU is powered off at this time, and the first target pin corresponding to the intelligent high-side chip is in a preset level state. At this time, the two conditions are met, and the intelligent high-side chip can enter the low-power mode. In the low-power mode, the external monitoring module can be powered on. The working voltage of the monitoring module is set to 12V, and the working current is 500mA. At this time, the IDL pin is at low level.

[0070] Among them, the external monitoring module can include a sensor module and a radar module, specifically, it can include a rain sensor, a collision avoidance radar, etc., which is not limited in the present application.

[0071] It should be noted that for the intelligent high-side chip, there are multiple pins, different pins have different functions, and the corresponding external monitoring modules connected are also different. Among them, the first target pin includes the DEN pin and the EN pin, and the first target pin corresponding to the intelligent high-side chip is in a preset level state, that is, the DEN pin is at low level, and the EN pin is at constant power pull-up high level.

[0072] The second target pin is the IDL pin, which is at low level when the intelligent high-side chip enters the low-power mode.

[0073] Subsequently, other pins, such as the third target pin connected to the external monitoring module, can diagnose which specific external monitoring module the source of the wake-up signal corresponds to.

[0074] Step 102, in the case of detecting that the working current of the external monitoring module in the low-power mode is greater than the preset threshold, starting the normal mode, and generating a wake-up signal through the second target pin in the normal mode;

[0075] Further, the starting the normal mode in the case that the working current of the external monitoring module in the low-power mode is greater than a preset threshold value comprises:

[0076] monitoring the working current of the external monitoring module in the low-power mode, an initial working current of the external monitoring module being a first current value;

[0077] judging whether the working current is greater than a preset threshold value, wherein the first current value is less than the preset threshold value;

[0078] if yes, starting the normal mode.

[0079] It should be noted that in the embodiment of the present application, after the vehicle is powered off in the sleep mode, the intelligent high-side chip starts to monitor the working current of the external monitoring module, and the initial working current of the external monitoring module is the first current value, for example, the initial working voltage of the monitoring module is set to 12V, and the initial working current is the first current value, 500mA.

[0080] In the working process of the external monitoring module, the intelligent high-side chip continuously monitors, and if it is detected that the working current of the external monitoring module exceeds the preset threshold value, it means that an emergency situation may occur, such as rain or vehicle impact. At this time, the intelligent high-side chip exits the low-power mode and enters the normal mode, i.e., the Normal mode, at this time, the working voltage of the monitoring module can be set to 12V, and the working current is 2A.

[0081] The preset threshold value can be 1A, and the present application does not make specific limitation, which can be set according to different vehicles and different situations.

[0082] Further, the second target pin in the low-power mode is in a low level state; and the generating a wake-up signal through the second target pin in the normal mode comprises:

[0083] controlling the low level state of the second target pin to be converted to a high level state in the normal mode;

[0084] generating a high level signal based on the high level state, and taking the high level signal as the wake-up signal.

[0085] It should be noted that in the embodiment of the present application, after the intelligent high-side chip exits the low-power mode, the second target pin, i.e., the IDL pin, is flipped from the low level to the high level, and the IDL signal is directly used as a wake-up source to wake up the power management chip.

[0086] Step 103, waking up the vehicle body domain controller through the wake-up signal, so that the vehicle body domain controller detects a target controller corresponding to the external monitoring module.

[0087] Further, the waking up the vehicle body domain controller by the wake-up signal comprises:

[0088] waking up a power management chip by the wake-up signal, so that the power management chip controls a battery module to supply power to a micro controller unit, and the micro controller unit wakes up the vehicle body domain controller.

[0089] It should be noted that in the embodiment of the present application, after the intelligent high-side chip exits the low-power consumption mode, the IDL pin will be flipped from low level to high level, and the IDL signal will directly wake up the power management chip as a wake-up source, and the power supply is powered on to the MCU, thereby waking up the entire vehicle body domain controller.

[0090] After the vehicle body domain controller is woken up, at this time, since the intelligent high-side chip can diagnose the wake-up source through the GPIO diagnosis, it can be diagnosed which monitoring module has a current change.

[0091] In the embodiment of the present application, the intelligent high-side chip is applied, the intelligent high-side chip is integrated with a current detection circuit, the intelligent high-side chip is connected with an external monitoring module, in a case that it is detected that the vehicle body domain controller is in a sleep state and a first target pin corresponding to the intelligent high-side chip is in a preset level state, a low-power consumption mode is started; in a case that it is detected that a working current corresponding to the external monitoring module is greater than a preset threshold value in the low-power consumption mode, a normal mode is started, and a wake-up signal is generated through a second target pin in the normal mode; the vehicle body domain controller is woken up by the wake-up signal, so that the vehicle body domain controller detects a target controller corresponding to the external monitoring module. Through the integrated current detection circuit of the intelligent high-side chip, efficient energy consumption management and accurate wake-up control of the vehicle system are realized. In the sleep state of the vehicle body domain controller, the intelligent high-side chip can automatically enter the low-power consumption mode, which significantly reduces the system energy consumption and prolongs the battery life. At the same time, when the working current of the external monitoring module exceeds the preset threshold value, the intelligent high-side chip can timely detect the change and quickly switch from the low-power consumption mode to the normal mode, generate a wake-up signal through the second target pin, and accurately wake up the vehicle body domain controller. Not only the response speed and reliability of the system are improved, but also the fault troubleshooting and maintenance process are simplified through accurate wake-up source diagnosis, and the safe and stable operation of the vehicle system is ensured.

[0092] Figure 2 is a step flow chart of another vehicle sleep monitoring method provided by the embodiment of the present application, as shown in Figure 2 the method is applied to an intelligent high-side chip, the intelligent high-side chip is integrated with a current detection circuit, the intelligent high-side chip is connected with an external monitoring module, and can comprise:

[0093] In step 201, when it is detected that the body domain controller is in a sleep state and the first target pin corresponding to the intelligent high-side chip is in a preset level state, a low-power mode is started.

[0094] In step 202, when it is detected that the working current of the external monitoring module in the low-power mode is greater than a preset threshold, a normal mode is started, and a wake-up signal is generated through the second target pin in the normal mode.

[0095] It should be noted that steps 201-202 are described above and will not be repeated here.

[0096] In step 203, the wake-up signal is used to wake up the body domain controller, a target controller of a target external monitoring module in the external monitoring module is determined through pin diagnosis of the wake-up signal, so that the body domain controller detects the target controller corresponding to the external monitoring module.

[0097] It should be noted that in the embodiment of the application, after the intelligent high-side chip exits the low-power mode, the IDL pin will be flipped from low to high, and the IDL signal will be used as a wake-up source to directly wake up the power management chip, and the power supply is powered on to the MCU, thereby waking up the entire body domain controller.

[0098] After the body domain controller is woken up, since the intelligent high-side chip can diagnose the wake-up source through the GPIO, it can be diagnosed which monitoring module has a current change.

[0099] In an embodiment of the application, the external monitoring module includes a sensor module, the sensor module includes a rain sensor, and the target controller of the target external monitoring module in the external monitoring module is determined through pin diagnosis of the wake-up signal, including: the target external monitoring module in the external monitoring module is determined to be the rain sensor through pin diagnosis of the wake-up signal.

[0100] The body domain controller detects the target controller corresponding to the external monitoring module, including: the body domain controller determines whether the window is closed through the window controller corresponding to the rain sensor; if not, the window is controlled to be closed.

[0101] It should be noted that the external monitoring module includes a sensor module, and the sensor module includes a rain sensor. Specifically, when the rain sensor current changes by 500mA-2A, it indicates that it is raining, and the body controller detects whether the window is closed. If not, the motor is driven to close the window.

[0102] In another embodiment of the present application, the external monitoring module includes a radar module, and the radar module includes a collision avoidance radar. The target controller of the target external monitoring module is determined by diagnosing the wake-up signal through the pin, including: the target external monitoring module is determined to be the collision avoidance radar by diagnosing the wake-up signal through the pin.

[0103] The vehicle body domain controller detects the target controller corresponding to the external monitoring module, including: the vehicle body domain controller determines the collision position corresponding to the collision avoidance radar, and wakes up the telematics module, and sends the collision position to the user terminal through the telematics module.

[0104] It should be noted that the external monitoring module includes a radar module, and the radar module includes a collision avoidance radar. Specifically, when the current of the collision avoidance radar changes by 500mA-2A, it indicates that a collision is detected, and the vehicle body controller detects the damaged collision position and wakes up the T-BOX (telematics module) through CAN. The T-BOX uploads the damaged state of the vehicle to the cloud and feeds back to the user's smart mobile terminal.

[0105] It should be noted that in the embodiments of the present application, the above-mentioned two external monitoring modules are not the only limitation. Not only rain and vehicle collision, but also fire or vehicle theft and other scenarios can be detected through the current change of the corresponding external monitoring module, so as to wake up the vehicle body domain controller through the intelligent high-side chip to detect and control the specific controller. Therefore, in the face of any type of emergency, the present application can respond in time, thereby further enhancing the safety of the vehicle.

[0106] The present application realizes efficient energy consumption management and accurate wake-up control of the vehicle system through the integrated current detection circuit of the intelligent high-side chip. In the sleep state of the vehicle body domain controller, the intelligent high-side chip can automatically enter the low-power mode, significantly reducing the system energy consumption and prolonging the battery life. At the same time, when the working current of the external monitoring module exceeds the preset threshold, the intelligent high-side chip can detect this change in time and quickly switch from the low-power mode to the normal mode, generate a wake-up signal through the second target pin, and accurately wake up the vehicle body domain controller. Not only improves the response speed and reliability of the system, but also simplifies the fault diagnosis and maintenance process through accurate wake-up source diagnosis, and ensures the safe and stable operation of the vehicle system.

[0107] In addition, the embodiment of the present application can handle various types of emergency situations, such as rain without closing the window, left front and right front collision, rear-end collision, etc., and provide timely response to enhance the safety of the vehicle. When the vehicle encounters an emergency situation, such as rain or vehicle impact, etc., the technical solution can close the window or wake up the T-BOX to send a reminder information to the owner through the cloud, so that the user can know the status of the vehicle in time, and the user experience is improved.
