[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The embodiment of the present invention provides a vehicle control method, which is applicable to a vehicle-mounted controller, wherein the vehicle-mounted controller is connected to a panoramic camera system, and is used to control the operation of the panoramic camera system (Around View Monitoring, referred to as AVM) according to actual conditions when the vehicle enters the extreme endurance mode, and to display the reversing image in time to meet the needs of users. The vehicle-mounted controller here is a controller set on the vehicle, which can be one controller or multiple controllers on the vehicle.

[0048] In one embodiment, if Figure 1 As shown, a vehicle control method is provided, which is described by taking the method applied to a vehicle controller as an example, and includes the following steps:

[0049] S1: When the vehicle is in the extreme endurance mode, obtaining first vehicle data;

[0050] S2: When the first vehicle data meets a preset wake-up condition, wake up the panoramic camera system and control the panoramic camera system to display a reversing image.

[0051] Among them, the extreme endurance mode is a mode that extends the usage time by limiting the use of certain functions when the battery is about to run out.

[0052] The first vehicle data is vehicle data collected in real time for evaluating whether the panoramic camera system needs to be awakened. Awakening the panoramic camera system here refers to the process of controlling the panoramic camera system in a power-off state to be powered on so that the panoramic camera system can output a reversing image. The preset awakening condition includes a pre-set condition for awakening the panoramic camera system, specifically a pre-set condition for evaluating whether there is a need to reverse.

[0053] As an example, in S1, when the vehicle is in the extreme endurance mode, the on-board controller can determine that the panoramic camera function is restricted from use, that is, the panoramic camera system connected to the on-board controller is in a power-off state. At this time, the first vehicle data can be obtained through the CAN bus or other methods.

[0054] As an example, in S2, after obtaining the first vehicle data, the on-board controller compares the first vehicle data with the preset wake-up condition. When the first vehicle data meets the preset wake-up condition, it can be determined that the first vehicle data reflects that the user has a need to reverse. At this time, the panoramic camera system is woken up to power on the panoramic camera system that is in a power-off state, so that the panoramic camera system can capture the reversing image, and according to the actual situation, the panoramic camera system is controlled to display the reversing image in time, so as to achieve the goal of timely controlling the panoramic camera system in the extreme endurance mode to display the reversing image according to the real-time collected vehicle data, which can not only ensure the low power consumption of the whole vehicle, but also avoid the delay in the reversing image display.

[0055] like Figure 2 As shown, the panoramic camera system includes an intelligent driving domain controller, a camera, a multimedia host and a vehicle display screen. The camera is connected to the intelligent driving domain controller. When the multimedia host is connected to the intelligent driving domain controller or the camera, the vehicle controller wakes up the panoramic camera system, and specifically controls the intelligent driving domain controller and the camera to power on, so that the camera in the panoramic camera system collects reversing images, and sends the collected reversing images to the multimedia host or sends them to the multimedia host through the intelligent driving domain controller, so that the multimedia host can control the vehicle display screen to display the reversing image according to actual conditions, for example, when the multimedia host receives a control instruction for displaying the reversing image.

[0056] In this example, when the first vehicle data meets the preset wake-up condition, the panoramic camera system is awakened to capture the reversing image, and the reversing image is displayed in a timely manner, so as to achieve the goal of timely controlling the panoramic camera system in the extreme endurance mode to display the reversing image based on the real-time collected vehicle data, which can not only ensure the low power consumption of the whole vehicle, but also avoid the delay in the reversing image display.

[0057] In one embodiment, step S2, i.e., controlling the panoramic camera system to display a reversing image, includes:

[0058] Acquire second vehicle data, and when the second vehicle data meets a preset display condition, control the panoramic camera system to display the reversing image.

[0059] The second vehicle data is vehicle data collected in real time for evaluating whether the panoramic camera system displays a reversing image. The preset display condition includes a preset condition for controlling the panoramic camera system to display a reversing image, specifically a preset condition for evaluating whether it is necessary to display a reversing image.

[0060] As an example, when the first vehicle data meets the preset wake-up condition, the on-board controller may determine that the first vehicle data reflects that the user has a need to reverse. At this time, the on-board controller wakes up the panoramic camera system, for example, controls the intelligent driving domain controller in the panoramic camera system and the camera connected thereto to power on, so that the camera of the panoramic camera system can capture the reversing image in advance and output the reversing image to the multimedia host; and, after waking up the panoramic camera system, it is also necessary to obtain the second vehicle data through the CAN bus or other means, and compare the second vehicle data with the preset display condition. When the second vehicle data meets the preset display condition, the panoramic camera system that has been awakened in advance can be controlled to display the reversing image. Specifically, the multimedia host can control the vehicle display screen to display the reversing image, so that the panoramic camera system can display the reversing image in time to avoid delay in the reversing image display response.

[0061] In this example, when the first vehicle data meets the preset wake-up condition, the panoramic camera system is first woken up to capture the reversing image, so that when the second vehicle data meets the preset display condition, the panoramic camera system can be controlled to display the reversing image in time, so as to achieve the goal of timely controlling the panoramic camera system in the extreme endurance mode to display the reversing image based on the real-time collected vehicle data, which can not only ensure the low power consumption of the entire vehicle, but also avoid the delay in the reversing image display.

[0062] In one embodiment, the first vehicle data includes a first gear; and the preset wake-up condition includes that the first gear is a reverse gear.

[0063] As an example, when the vehicle is in the extreme endurance mode, the on-board controller obtains the first vehicle data of the first gear. When the first gear is the reverse gear (i.e., the R gear), it can be determined that the user is currently performing a reversing operation, and the reversing process may require controlling the panoramic camera system to display the reversing image. Therefore, it can be determined that the preset wake-up condition is met and the panoramic camera system needs to be woken up in advance, that is, the panoramic camera system connected to the on-board controller needs to be powered on so that the camera of the panoramic camera system can capture the reversing image, so as to promptly respond to the user's need to view the reversing image later.

[0064] In one embodiment, the first vehicle data further includes a current vehicle speed; and the preset wake-up condition further includes that the current vehicle speed is less than a preset vehicle speed.

[0065] The current vehicle speed is the vehicle speed collected at the current moment. The first gear is the gear triggered by the user at the current moment, which is used to evaluate whether the preset wake-up condition is met. The preset vehicle speed is a pre-set vehicle speed, specifically a vehicle speed used to evaluate whether there is a need to reverse, for example, the preset vehicle speed can be set to 10kph.

[0066] As an example, when the vehicle is in the extreme endurance mode, the on-board controller obtains first vehicle data such as the current vehicle speed and the first gear. When the current vehicle speed is less than the preset vehicle speed and the first gear is the reverse gear (i.e., R gear), it can be determined that the user is currently performing a reversing operation, and the reversing process may require controlling the panoramic camera system to display the reversing image. Therefore, it can be determined that the preset wake-up conditions are met and the panoramic camera system needs to be woken up in advance, that is, the panoramic camera system connected to the on-board controller needs to be powered on so that the camera of the panoramic camera system can capture the reversing image, so as to promptly respond to the user's need to view the reversing image later.

[0067] In this example, when the current vehicle speed is less than the preset speed, the on-board controller needs to continuously monitor its first gear. When the user triggers the reverse gear (i.e., R gear), it monitors that the first gear is the reverse gear (i.e., R gear), and determines that the user may need to control the panoramic camera system to display the reversing image. It determines that the first vehicle data meets the preset wake-up condition, so as to wake up the camera of the panoramic camera system to capture the reversing image in advance, so that the panoramic camera system can display the reversing image in time, avoiding delay in the reversing image display response.

[0068] In one embodiment, the second vehicle data is a second gear position;

[0069] The preset display condition includes that the second gear position is not detected as the parking gear within the first time period.

[0070] The second gear is the gear triggered by the user monitored at the current moment, and is used to evaluate whether the preset display condition is met. The first time period is a preset time period for evaluating whether the user has completed the reverse operation, for example, the first time period can be set to 5s.

[0071] As an example, the vehicle controller starts timing after waking up the panoramic camera system, and continuously monitors the second gear position within the first time period. When the second gear position is not detected as the parking gear (i.e., P gear), that is, the vehicle gear position is not detected to be changed from the reverse gear (i.e., R gear) to the parking gear (i.e., P gear) within the first time period, it means that the user has not completed the reverse operation within the first time period. At this time, it is determined that the user has a need to view the reverse image. Therefore, it is determined that the preset display condition is met, and it is necessary to control the panoramic camera system to display the reverse image to ensure the response speed of the reverse image display. Accordingly, when the vehicle controller detects that the second gear position is the parking gear (i.e., P gear) within the first time period, that is, the vehicle gear position is detected to be changed from the reverse gear (i.e., R gear) to the parking gear (i.e., P gear) within the first time period, it means that the user has completed the reverse operation within the first time period, and there is no need to control the panoramic camera system to display the reverse image. Therefore, it is determined that the preset display condition is not met.

[0072] In one embodiment, the first vehicle data includes current vehicle speed and user operation data;

[0073] The preset wake-up condition includes that the current vehicle speed is less than a preset vehicle speed, and the user operation data includes parking requirement data.

[0074] The user operation data is the data generated by the user operating the function buttons, control switches and other human-machine interaction interfaces of the vehicle. The parking demand data is the data used to reflect the user's parking demand.

[0075] As an example, when the vehicle is in the extreme endurance mode, the on-board controller obtains the current vehicle speed and user operation data. When the current vehicle speed is less than the preset speed and the user operation data includes parking requirement data, it can be determined that the vehicle is currently traveling at a low speed and the user has a parking requirement, and it is determined that the user may perform a reversing operation. The reversing process may require controlling the panoramic camera system to display the reversing image. Therefore, it can be determined that the preset wake-up conditions are met and the panoramic camera system needs to be woken up in advance, that is, the panoramic camera system connected to the on-board controller needs to be powered on so that the camera of the panoramic camera system can capture the reversing image in advance, so as to promptly respond to the user's need to view the reversing image later.

[0076] In this example, when the vehicle-mounted controller detects that the current vehicle speed is less than the preset vehicle speed, it needs to continuously collect user operation data, analyze the user operation data according to the preset parking demand analysis rules, and determine whether the user operation data includes parking demand data. When it is determined that the user operation data includes parking demand data, it is determined that the user may need to control the reversing image displayed by the panoramic camera system. Therefore, it is determined that the first vehicle data meets the preset wake-up condition to wake up the camera of the panoramic camera system to collect the reversing image in advance, so that the panoramic camera system can display the reversing image in time to avoid delay in the reversing image display response.

[0077] In one embodiment, the parking requirement data includes parking space search data or parking function instructions.

[0078] The parking space search data is data collected during the user's search for parking spaces. As an example, when the vehicle controller detects the parking space search data generated by the user searching for nearby parking spaces on the multimedia host or other terminals communicating with the vehicle controller, it can be determined that the user has a parking demand, and therefore the parking space search data can be determined as parking demand data.

[0079] The parking function instruction is an instruction triggered by the user to implement the parking function. As an example, after the vehicle controller detects the parking function instruction triggered by the user operating the parking function switch or the parking function button, it can determine that the user has a parking demand, and therefore, the parking function instruction can be determined as the parking demand data.

[0080] In one embodiment, the second vehicle data includes a second gear;

[0081] The preset display condition includes monitoring that the second gear is the reverse gear within the second time period.

[0082] The second gear is the gear triggered by the user detected at the current moment, and is used to evaluate whether the preset display condition is met. The second time period is a pre-set time period, and is used to evaluate whether to control the panoramic camera system to exit the awake state. Specifically, it can be understood as a time period used to evaluate whether it is necessary to control the intelligent driving domain controller and the camera in the panoramic camera system to enter the power-off state again.

[0083] As an example, after the on-board controller wakes up the panoramic camera system so that the panoramic camera system collects the reversing image, it continuously monitors the second gear position in the second time period. When it detects that the second gear position is the reverse gear (i.e., R gear), it can be determined that the user is currently performing a reversing operation, and the awakened panoramic camera system can be controlled to display the reversing image it has collected in advance, thereby ensuring the response speed of the reversing image display. Accordingly, if the on-board controller does not detect that the second gear position is the reverse gear (i.e., R gear) in the second time period, it means that the user did not perform a reversing operation in the second time period after the panoramic camera system is awakened, and there is no need to continuously collect the reversing image. Therefore, it is determined that the preset display condition is not met.

[0084] In one embodiment, after acquiring the second vehicle data, the vehicle control method further includes:

[0085] If the second vehicle data does not meet the preset display condition, the panoramic camera system is controlled to be powered off.

[0086] As an example, after waking up the panoramic camera system, if the second vehicle data collected by the vehicle controller does not meet the preset display conditions, it can be determined that there is no need to control the panoramic camera system to display the reversing image. Therefore, the panoramic camera system can be controlled to power off to save power consumption in the extreme endurance mode.

[0087] For example, when the current vehicle speed is less than the preset vehicle speed and the first gear is the reverse gear, the on-board controller wakes up the panoramic camera system and then starts timing, continuously monitoring the second gear within the first time period, and when it is detected that the second gear is the parking gear (i.e., P gear), that is, it is detected that the vehicle gear has changed from the reverse gear (i.e., R gear) to the parking gear (i.e., P gear) within the first time period, indicating that the user has completed reversing within the first time period, and there is no need to control the panoramic camera system to display the reversing image. Therefore, it is determined that the preset display conditions are not met, and the panoramic camera system needs to be powered off to save power consumption of the panoramic camera system.

[0088] For example, when the current vehicle speed is less than the preset vehicle speed and the user operation data includes parking requirement data, the on-board controller wakes up the panoramic camera system and starts timing, and continuously monitors the second gear within the second time period. If the second gear is not detected to be the reverse gear (i.e., R gear), it means that the user did not perform any reverse operation within the second time period after the panoramic camera system was woken up, and there is no need to continuously collect reversing images. Therefore, it is determined that the preset display conditions are not met, and the panoramic camera system needs to be powered off to save power consumption of the panoramic camera system.

[0089] In one embodiment, the preset display condition includes that the second vehicle data includes an image display instruction.

[0090] Among them, the image display instruction is an instruction actively triggered by the user to control the panoramic camera system to display the reversing image.

[0091] As an example, after waking up the panoramic camera system so that the camera of the panoramic camera system captures the reversing image, the vehicle-mounted controller can obtain the second vehicle data through the CAN bus or other communication methods. When the second vehicle data includes an image display instruction actively triggered by the user, it can be determined that the user wants to view the reversing image. Therefore, it can be determined that the second vehicle data meets the preset display conditions, and the awakened panoramic camera system is controlled to promptly display the reversing image captured in advance, that is, the multimedia host controls the vehicle display screen to promptly display the reversing image, thereby ensuring the response speed of the reversing image display.

[0092] In one embodiment, before acquiring the first vehicle data when the vehicle is in the extreme endurance mode, the vehicle control method further includes:

[0093] In response to the extreme endurance mode signal, the panoramic camera system is controlled to be powered off.

[0094] Among them, the extreme endurance mode signal is a signal used to control the vehicle to enter the extreme endurance mode. The extreme endurance mode signal can be a signal actively triggered by the user when the vehicle is in an extreme working condition, or it can be a signal automatically triggered when it is determined that the vehicle is in an extreme working condition based on actual measured data.

[0095] As an example, the vehicle controller obtains the extreme endurance mode signal through the CAN bus or other communication methods. After obtaining the extreme endurance mode signal, it can be determined that the vehicle is in an extreme working condition. In order to save power consumption, the panoramic camera system needs to be powered off. In this example, after the vehicle controller controls the panoramic camera system to power off, it can determine whether to control the vehicle to enter the extreme endurance mode according to the actual situation to ensure the vehicle's endurance mileage under extreme working conditions.

[0096] In one embodiment, before acquiring the first vehicle data when the vehicle is in the extreme endurance mode, the vehicle control method further includes:

[0097] In response to the extreme endurance mode signal and the power-off request signal triggered by the panoramic camera system, the panoramic camera system is controlled to be powered off.

[0098] The power-off request signal is a signal for requesting power-off triggered by the panoramic camera system, specifically a signal for requesting power-off triggered by the panoramic camera system in response to the extreme endurance mode signal.

[0099] As an example, after receiving the extreme endurance mode signal, the on-board controller may send the extreme endurance mode signal to the panoramic camera system so that the panoramic camera system understands that the vehicle is in an extreme working condition. After the panoramic camera system receives the extreme endurance mode signal, it needs to send a request power-off signal to the on-board controller, so that when the on-board controller receives the request power-off signal, it controls the panoramic camera system to power off so that the vehicle enters the extreme endurance mode to ensure the vehicle's range under extreme working conditions. In this example, the on-board controller will control the panoramic camera system to power off so that the vehicle enters the extreme endurance mode only after receiving the extreme endurance mode signal and the request power-off signal, so as to achieve the effect of preventing false triggering.

[0100] For example, when the on-board controller includes a vehicle controller and a body domain controller, both the vehicle controller and the body domain controller are connected to the panoramic camera system. After receiving the extreme endurance mode signal, the vehicle controller can send the extreme endurance mode signal to the panoramic camera system and the body domain controller; after obtaining the extreme endurance mode signal, the panoramic camera system can determine that the vehicle is in an extreme working condition. At this time, it can send a power-off request signal to the body domain controller; after receiving the extreme endurance mode signal and the power-off request signal, the body domain controller can determine that it is not an error operation, and can control the panoramic camera system to power off, and specifically control the relay connecting the battery and the panoramic camera system to disconnect, so that the intelligent driving domain controller and the camera are in a power-off state, so that the vehicle enters the extreme endurance mode. Accordingly, when the vehicle is in the extreme endurance mode, if the first vehicle data meets the preset wake-up conditions, the battery and the relay of the panoramic camera system can be controlled to be energized, so that the battery can power the panoramic camera system to wake up the panoramic camera system, so that the intelligent driving domain controller and the camera are powered on, and the camera of the panoramic camera system collects the video stream of the reversing image, and sends the video stream to the multimedia host or sends it to the multimedia host through the intelligent driving domain controller; after the panoramic camera system is awakened, if the second vehicle data meets the preset display conditions, the multimedia host can control the vehicle display screen to display the reversing image in time to ensure the display efficiency of the reversing image.

[0101] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0102] In one embodiment, a vehicle controller is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the vehicle control method in the above embodiment is implemented, for example Figure 1 S1-S2 shown are not described here again to avoid repetition.

[0103] In one embodiment, if Figure 2 As shown, a vehicle control system is provided, including a battery, a relay, a panoramic camera system and the vehicle-mounted controller in the above embodiment;

[0104] The panoramic camera system is connected to the battery via the relay;

[0105] The vehicle-mounted controller is connected to the relay and is used to control the operation of the relay and the panoramic camera system.

[0106] As an example, the battery is connected to the panoramic camera system through a relay. When the relay is closed, the battery supplies power to the panoramic camera system, and the panoramic camera system is in a powered-on state. Conversely, when the relay is disconnected, the battery does not supply power to the panoramic camera system, and the panoramic camera system is in a powered-off state, so as to save power. The on-board controller is connected to the relay, and can control the closing or disconnection of the relay according to the measured data to power on or off the panoramic camera system, and communicate with the panoramic camera system when the panoramic camera system is powered on, so that the panoramic camera system can display the reversing image.

[0107] In this example, when the vehicle is in the extreme endurance mode, the on-board controller needs to control the relay to disconnect, so that the panoramic camera system is in a power-off state; when the first vehicle data meets the preset wake-up condition, the panoramic camera system is first awakened to capture the reversing image, so that the panoramic camera system is powered on, and the camera of the panoramic camera system captures the video stream of the reversing image; when the second vehicle data meets the preset display condition, the panoramic camera system's vehicle display screen can be controlled to display the reversing image, so as to achieve the goal of timely controlling the panoramic camera system in the extreme endurance mode to display the reversing image based on the real-time collected vehicle data, thereby avoiding delays in the reversing image display and affecting the user experience.

[0108] In one embodiment, if Figure 2 As shown, the panoramic camera system includes an intelligent driving domain controller, a camera, a multimedia host and a vehicle display screen;

[0109] The intelligent driving domain controller is connected to the battery via a relay and communicates with the on-board controller;

[0110] The camera is connected to the intelligent driving domain controller and is used to collect reversing images based on the power supply of the intelligent driving domain controller;

[0111] The multimedia host is connected to the intelligent driving domain controller or the camera, and is connected to the vehicle display screen, and is used to control the vehicle display screen to display the reversing image.

[0112] As an example, a power supply link for a panoramic camera system is formed between a battery, a relay, an intelligent driving domain controller and a camera.

[0113] The intelligent driving domain controller is powered by normal electricity. There is a relay between the battery and the intelligent driving domain controller. The relay is controlled by the vehicle controller to be energized or disconnected, thereby powering on or off the intelligent driving domain controller. When the vehicle is in non-extreme endurance mode, the vehicle controller needs to continuously send a relay energization signal to close the relay and continuously power the intelligent driving domain controller, so that the intelligent driving domain controller can power the camera, and the camera can capture the reversing image and send the reversing image to the multimedia host; in the extreme endurance mode, the vehicle controller needs to send a relay disconnection signal to disconnect the relay, the intelligent driving domain controller is powered off, and the camera connected to the intelligent driving domain controller is also powered off, so that the camera no longer captures the reversing image.

[0114] The camera is connected to the intelligent driving domain controller, which controls power supply or power off. When the vehicle is in non-extreme endurance mode, the on-board controller needs to continuously send a relay closure signal to close the relay, thereby maintaining the intelligent driving domain controller to provide continuous power to the camera; when the vehicle is in extreme endurance mode, the on-board controller needs to send a relay disconnection signal to disconnect the relay, so that the camera is powered off and does not collect the video stream corresponding to the reversing image.

[0115] The multimedia host is a host for controlling the operation of the vehicle display screen. The vehicle display screen can be directly connected to the camera to receive the reversing image collected by the camera; it can also be connected to the camera through the intelligent driving domain controller to receive the reversing image collected by the camera forwarded by the intelligent driving domain controller; and according to the actual situation, the vehicle display screen is controlled to display the reversing image. In this example, the multimedia host and the intelligent driving domain controller are powered by different power supplies, and the power on and off of the multimedia host are not affected by the relay. After the vehicle is started, the multimedia host enters the power-on state. When the vehicle is in the extreme endurance mode, the multimedia host can control the vehicle display screen to enter the screen-off state to save power consumption; when the vehicle is in the non-extreme endurance mode, the intelligent driving domain controller and the camera are powered on, so that the camera can collect the reversing image and output it to the multimedia host in the power-on state. When the second vehicle data meets the preset display conditions, the multimedia host can control the vehicle display screen to exit the screen-off state and display the reversing image.

[0116] For example, the vehicle controller is Figure 2The body domain controller in the vehicle includes four surround-view cameras. When the vehicle is in the extreme endurance mode, if the first vehicle data obtained by the body domain controller meets the preset wake-up condition, the body domain controller needs to send a relay closure signal to close the relay, and the intelligent driving domain controller and the camera connected thereto are powered on, so as to wake up the panoramic camera system, so that the camera in the panoramic camera system can capture the reversing image and send the reversing image to the multimedia host; if the second vehicle data obtained by the body domain controller meets the preset display condition, it is necessary to send a control signal to the intelligent driving domain controller, so that the intelligent driving domain controller controls the vehicle display screen connected thereto to display the reversing image through the multimedia host; or, after receiving the image display instruction, the multimedia host can also control the vehicle display screen to display the reversing image.

[0117] In one embodiment, if Figure 2 As shown, the vehicle-mounted controller includes a body domain controller and a vehicle controller;

[0118] The vehicle controller is connected to the body domain controller and the intelligent driving domain controller, and is used to send the extreme endurance mode signal to the body domain controller and the intelligent driving domain controller, and send the measured vehicle data to the body domain controller;

[0119] The intelligent driving domain controller is connected to the body domain controller, and is used to send a power-off request signal to the body domain controller based on the extreme endurance mode signal;

[0120] The body domain controller is connected to the relay, and is used to control the relay to be disconnected based on the extreme endurance mode signal and the request power-off signal; and to control the relay to be attracted based on the measured vehicle data.

[0121] As an example, when it is necessary to control the vehicle to enter the extreme endurance mode, the vehicle controller synchronously sends the extreme endurance mode signal to the intelligent driving domain controller and the body domain controller. The intelligent driving domain controller then sends a power-off request signal to the body domain controller. After the body domain controller receives the corresponding extreme endurance mode signal and the power-off request signal at the same time, it controls the relay to disconnect, so that the relay is disconnected and power is stopped to the intelligent driving domain controller and the camera connected to it, so as to save power and enable the vehicle to enter the extreme endurance mode.

[0122] Accordingly, when the vehicle is in the extreme endurance mode, the vehicle controller needs to send the measured vehicle data to the body domain controller, so that the body domain controller determines whether to control the relay to be energized according to the measured vehicle data, so as to power on the panoramic camera system. The measured vehicle data here includes the first vehicle data and the second vehicle data. Specifically, the vehicle controller can send the first vehicle data (which can be the current vehicle speed and the first gear, or the current vehicle speed and user operation data) to the body domain controller. When the first vehicle data meets the preset wake-up condition, the body domain controller sends a energizing signal to the relay to restore power to the intelligent driving domain controller and the camera connected thereto, so that the camera can collect the reversing image; after the relay is energized, the vehicle controller can send the second vehicle data (which can be the first gear) to the body domain controller. When the second vehicle data meets the preset display condition, the body domain controller can send a display control signal to the intelligent driving domain controller, so that the intelligent driving domain controller controls the vehicle display screen to display the reversing image through the multimedia host, so as to achieve timely response to the user's reversing image needs while ensuring low power consumption in the extreme endurance mode.

[0123] like Figure 3 As shown, when the preset vehicle speed is 10 kph, the first time period is 5 seconds, and the on-board controller includes a vehicle controller and a body domain controller connected thereto, the above vehicle control system realizes the control process of the extreme endurance mode:

[0124] S01: When the vehicle is powered on and it is detected that the vehicle is in an extreme working condition, the extreme endurance mode can be automatically triggered or operated by the user, so that the vehicle controller receives the extreme endurance mode signal and sends the extreme endurance mode signal to the intelligent driving domain controller and the body domain controller.

[0125] S02: After receiving the extreme endurance mode signal, the intelligent driving domain controller sends a power-off request signal to the body domain controller; after receiving the extreme endurance mode signal and the power-off request signal, the body domain controller triggers the relay to disconnect, the intelligent driving domain controller and the surround-view camera are powered off, and the reversing image is disconnected, causing the vehicle to enter the extreme endurance mode.

[0126] S03: When the vehicle enters the extreme endurance mode, the vehicle controller continuously sends the first vehicle data to the body domain controller, where the first vehicle data includes the current vehicle speed and the first gear, or the current vehicle speed and user operation data.

[0127] S04: The body domain controller determines whether the current vehicle speed is below 10 kph when the extreme endurance mode is triggered.

[0128] S05: When the current vehicle speed is less than or equal to 10 kph, the body domain controller continuously monitors the gear signal sent by the vehicle controller to determine whether the user triggers the R gear (first gear); if the R gear is triggered, the body domain controller sends a pull-in signal to the relay to control the relay to close, so that the intelligent driving domain controller and the surround-view camera are powered on, and the surround-view camera resumes collecting reversing images; otherwise, the gear signal is continuously monitored.

[0129] S06: After the intelligent driving domain controller and the surround-view camera are powered on so that the surround-view camera resumes collecting reversing images, the body domain controller determines whether the user has completed reversing within 5 seconds, that is, whether the current gear is switched from R gear to P gear (second gear) within the first time period of 5 seconds, and the reversing is considered to be completed.

[0130] S07: If the user completes reversing within 5 seconds, the body domain controller controls the vehicle display screen through the intelligent driving domain controller to turn off the screen directly, without displaying the reversing image, so that the panoramic camera system is powered off along with the entire vehicle.

[0131] S08: If the user does not complete the reverse within 5 seconds, the body domain controller controls the relay to continue to pull in to keep the reverse image transmission, so that the car screen displays the reverse image until the user completes the reverse. Trigger condition 1: If the user does not complete the reverse within 5 seconds, the reverse image can be awakened in about 5 seconds; Trigger condition 2: The user's vehicle speed continues to decrease and there is a need to stop, triggering the R gear (second gear).

[0132] S09: If the judgment result of S04 is no, or the judgment result of S10 is no and the R gear is not triggered, the current vehicle speed is continuously monitored.

[0133] S10: The body domain controller monitors whether the current vehicle speed continues to decrease to less than or equal to 10kphh, and whether the user operation data includes parking demand data. The parking demand data here includes parking space search data or parking function instructions, that is, the vehicle controller monitors the data generated by the user's parking space search process, or the vehicle controller monitors the instructions generated by the user triggering the operation of entering the parking function.

[0134] S11: If the condition of S10 is met, that is, the current vehicle speed is less than the preset speed and the user operation data includes parking demand data, the body domain controller sends a pull-in signal to the relay to control the relay to close, so that the intelligent driving domain controller and the surround-view camera are powered on, so that the surround-view camera resumes collecting reversing images and continuously monitors the gear signal within the second time period; if the R gear is detected within the second time period, it means that the user has a reversing operation, and step S08 is executed, that is, the body domain controller controls the relay to continuously pull in to maintain the reversing image transmission, so that the vehicle display screen displays the reversing image until the user completes reversing and controls the vehicle display screen to turn off.
