[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0031] In order to ensure the safety of vehicle driving, vehicles are usually equipped with emergency call systems, which can trigger an emergency call when a collision occurs and send the vehicle's location and other key information to the rescue center to ensure that rescue personnel can reach the accident scene as soon as possible. However, after a vehicle collision, the power supply system inside the vehicle may be affected by the collision and cause power consumption too fast. The power is exhausted before the emergency call is triggered. This may result in the inability to transmit necessary information when the collided vehicle needs emergency rescue, thereby delaying the rescue time.

[0032] An embodiment of the present application provides a vehicle control method, which can determine the current working mode of the power supply system when a collision of the vehicle is detected. Afterwards, when the working mode is the low-voltage mode, the power supply to the redundant system is stopped, and a quick access to the emergency call system is provided. Among them, the redundant system is a system other than the emergency call system. When the power supply system is affected by a collision and the power consumption is lost too quickly, the loss of power of the power supply system by systems other than the emergency call system is avoided, the time when the power supply system is exhausted is delayed, and the remaining power is supplied to the emergency call system as much as possible, so as to maximize the protection of consumer rights and interests and improve user experience.

[0033] The vehicle control method provided in the embodiment of the present application can be implemented by a vehicle control device, and the vehicle control device provided in the embodiment of the present application can be hardware or software. When the vehicle control device is hardware, it can be various electronic devices with a vehicle control function, including but not limited to vehicle-mounted equipment, smart vehicles, mobile phones, computers, etc. When the vehicle control device is software, it can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules, or it can be implemented as a single software or software module, which is not specifically limited here.

[0034] Figure 1 A schematic diagram of the structure of a vehicle control device provided for an embodiment of the present application, the structure can be arranged in the processor or main control chip of the above-mentioned electronic device, for example, it can be arranged in the processor or main control chip of the vehicle computer. The vehicle control device can be logically divided into a business processing layer 11, an intermediate service layer 12, and a driver layer 13. Among them, the business processing layer 11 is used to process the business corresponding to the vehicle control device. For example, when the working mode is a low-voltage mode, the business processing layer 11 can stop powering the redundant system and provide a quick entrance to the emergency call system. The intermediate service layer 12 serves as a software middleware between the driver layer 13 and the business processing layer 11, and is used to manage and control hardware and software resources. The driver layer 13 is used to drive various hardware. For example, the driver layer 13 can drive the power supply system to power the emergency call system. Of course, Figure 1 The device structure shown in the figure does not constitute a limitation on the vehicle control device, except Figure 1 In addition to the layers shown, the vehicle control device may include Figure 1 More or fewer layers may be shown, or certain layers may be combined, or different layer arrangements may be used.

[0035] Figure 2 A flow chart of a vehicle control method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the vehicle control method may include the following steps.

[0036] S21. When a vehicle collision is detected, determine a current working mode of the power supply system.

[0037] Among them, the vehicle in the embodiment of the present application is a vehicle including a power supply system, for example, an electric vehicle, a hybrid vehicle, etc.

[0038] First, detect whether the vehicle has collided.

[0039] In some embodiments, a vehicle collision may be detected by detecting the vehicle body data in real time through a collision detection system, and determining that the vehicle collision has occurred based on the vehicle body data.

[0040] Exemplarily, the collision detection system may include an acceleration sensor for measuring the acceleration of the vehicle. When it is detected that the acceleration exceeds an acceleration threshold, the collision detection system determines that the vehicle has collided.

[0041] The collision detection system may also include a collision sensor, which is usually installed around the vehicle body and is used to detect whether a collision occurs around the vehicle body. For example, when at least one of the deformation of the vehicle body is detected to be greater than a deformation threshold and the vibration of the vehicle body exceeds a vibration threshold, the collision detection system determines that the vehicle has collided.

[0042] The collision detection system may also include a radar and a camera for detecting the vehicle's surrounding environment. When it is detected that the distance between the obstacle and the vehicle is less than a distance threshold, the collision detection system determines that the vehicle has collided.

[0043] Of course, the collision detection system can also use a vehicle collision detection model that has been pre-trained using artificial intelligence and machine learning algorithms, and input the vehicle's driving data or body data into the vehicle collision detection model to determine if the vehicle has collided.

[0044] Afterwards, determine the operating mode of the power supply system.

[0045] In some embodiments, the working mode of the power supply system may be determined by calling an interface of the power supply system to determine the working mode of the current power supply system. The working mode of the power supply system may include a low voltage mode. The low voltage mode refers to limiting the power output of the battery in the power supply system to protect the battery from damage caused by excessive discharge. The working mode of the power supply system may also include a maintenance mode, a camping mode, etc.

[0046] S22. When the working mode is the low voltage mode, the power supply to the redundant system is stopped, and a quick access to the emergency call system is provided.

[0047] The redundant system refers to the system other than the emergency call system, for example, the autonomous driving system, collision detection system, entertainment system, etc.

[0048] First, when the working mode is the low voltage mode, power supply to the redundant system is stopped.

[0049] In some embodiments, the method of stopping power supply to the redundant system may be to directly stop power supply to the redundant system through the power supply system.

[0050] In some embodiments, the method of stopping power supply to the redundant system may also be to send relevant instructions to the redundant system to instruct the redundant system to stop consuming power. For example, when the working mode is the low voltage mode, the vehicle body controller sends a synchronous waiting for rescue instruction to other controllers to instruct other controllers to enter the waiting for rescue mode.

[0051] Among them, other controllers include at least an entertainment controller in the entertainment system and an autonomous driving controller in the autonomous driving system. In the waiting rescue mode, the autonomous driving controller is used to cut off the power supply of all external devices of the autonomous driving system. The entertainment controller is used to reduce the brightness of the display screen to a preset brightness and cut off the power supply of other external devices in the entertainment system except the display screen. The preset brightness is pre-configured, such as a default value, or a brightness value set by relevant personnel according to actual conditions.

[0052] Afterwards, a quick access to the emergency call system is provided.

[0053] In some embodiments, a quick access to the emergency call system may be provided by establishing a connection between the emergency call system and any screen in the vehicle, and using the screen as a display screen of the emergency call system to display the quick access to the emergency call system. For example, a quick access to the emergency call system is provided on a display screen of an entertainment system.

[0054] In some embodiments, the vehicle control device may include a power supply system, a collision detection system, and a body controller. The power supply system is used to supply power to each system. The collision detection system is used to detect whether the vehicle has collided. The body controller is used to determine the current working mode of the power supply system when a collision of the vehicle is detected, and when the working mode is a low-voltage mode, stop the power supply of the redundant system through the power supply system, and provide a quick access to the emergency call system.

[0055] In some embodiments, the vehicle control device may include a power supply system, a collision detection system, a body controller, an entertainment controller, and an autonomous driving controller. The power supply system is used to supply power to each system. The collision detection system is used to detect whether the vehicle has collided. The body controller is used to determine the current working mode of the power supply system when a collision of the vehicle is detected, and when the working mode is a low-voltage mode, synchronously wait for rescue instructions. Among them, the waiting for rescue instruction is used to indicate entering the waiting for rescue mode. The entertainment controller is used to enter the waiting for rescue mode when receiving the waiting for rescue instruction, and reduce the brightness of the display screen to a preset brightness, cut off the power supply of other external devices in the entertainment system except the display screen, and provide a quick entrance to the emergency call system on the display screen. The autonomous driving domain controller is used to cut off the power supply of all external devices of the autonomous driving system when receiving the waiting for rescue instruction, and turn off autonomous driving related functions, such as radars, sensors, etc.

[0056] In the above scheme, first, when a vehicle collision is detected, the current working mode of the power supply system is determined. Afterwards, when the working mode is the low-voltage mode, the power supply to the redundant system is stopped, and a quick access to the emergency call system is provided. Among them, the redundant system is the system other than the emergency call system. In this way, after a vehicle collision is detected, the power supply to the systems other than the emergency call system is directly stopped, and only the power supply to the emergency call system is retained. This avoids the power loss of the power supply system by systems other than the emergency call system when the power supply system is affected by the collision and the power consumption is too fast. This delays the time when the power supply system is exhausted, and ensures that the remaining power is supplied to the emergency call system as much as possible, thereby maximizing the protection of consumer rights and interests and improving user experience.

[0057] In some embodiments, before step S22, the vehicle control method further includes:

[0058] S23. Obtain the remaining power of the power supply system.

[0059] In some embodiments, the remaining power of the power supply system can be obtained by reading the display data of the power supply system on the vehicle dashboard to determine the remaining power of the power supply system; or the remaining power of the power supply system can be obtained by calling relevant parameters of the power supply system.

[0060] S24. Display the remaining time according to the remaining power.

[0061] In some embodiments, the remaining time may be displayed according to the remaining power by counting the average power consumption of the current power supply system, and determining the remaining time according to the average power consumption and the remaining power. The average power consumption of the current power supply system may be counted by counting the total power consumption of the power supply system within a preset time period, and determining the remaining time according to the total power consumption and the preset time period. The preset time period is the time period after power supply to the redundant system is stopped.

[0062] In some embodiments, the method of displaying the remaining time according to the remaining power may also include the following steps:

[0063] S241. Determine, based on average power consumption and remaining power of the emergency call system, a usage time of the remaining power for powering the emergency call system.

[0064] First, determine the average power usage of the emergency call system.

[0065] In some embodiments, the average power consumption of the emergency call system may be determined by obtaining the historical power consumption of the emergency call system in a historical time period and calculating the average power consumption of the emergency call system based on the historical power consumption and the historical time period.

[0066] For example, according to the formula Calculate the average power consumption of the emergency call system, where S is used to represent the average power consumption of the emergency call system, V 历史 Used to indicate historical electricity consumption, T 历史 Used to represent historical time periods.

[0067] Afterwards, the usage time of the remaining power for powering the emergency call system is determined based on the average power consumption and the remaining power of the emergency call system.

[0068] For example, according to the formula Calculate the usage time of the remaining power for powering the emergency call system, where t is used to represent the usage time of the remaining power for powering the emergency call system, V 剩余 It is used to indicate the remaining power, and S is used to indicate the average power consumption of the emergency call system.

[0069] S242: Determine the usage time as the remaining time.

[0070] S243: Count down and display the remaining time.

[0071] In some embodiments, the countdown of the remaining time may be displayed by establishing a connection between the power supply system and any screen in the vehicle, and using the screen as the display screen of the power supply system to display the countdown of the remaining time. For example, the display screen of the entertainment system is used as the display screen of the power supply system, and the countdown of the remaining time is displayed on the display screen of the entertainment system.

[0072] In some embodiments, the countdown of the remaining time may also be displayed by establishing a connection between the power supply system and a screen displaying a quick entry to the emergency call system, and displaying the countdown of the remaining time on the screen. For example, the countdown of the remaining time and the quick entry to the emergency call system are simultaneously displayed on the display screen of the entertainment system.

[0073] In some embodiments, the countdown of the remaining time may also be displayed in that the power supply system includes a display screen, and the countdown of the remaining time is displayed on the display screen of the power supply system.

[0074] In the above scheme, the remaining power of the power supply system is obtained, and the remaining power is used to determine the duration of the emergency call system based on the average power consumption and the remaining power of the emergency call system. After that, the usage time is determined as the remaining time, and the remaining time is counted down and displayed. In this way, the power supply time of the power supply system can be displayed to the user to remind the user to make an emergency call within the power supply time and be prepared to wait for rescue, thereby protecting consumer rights and interests to the greatest extent and improving user experience.

[0075] In some embodiments, after step S21, the vehicle control method further includes: when the working mode is not the low voltage mode but the remaining time is less than the time threshold, controlling the power supply system to enter the low voltage mode. The time threshold is preset, for example, a default value, or a value set by relevant personnel according to actual conditions.

[0076] In some embodiments, the method of controlling the power supply system to enter the low voltage mode can be to send a mode conversion instruction to the power supply system to instruct the power supply system to enter the low voltage mode when it is determined that the working mode is not the low voltage mode but the remaining time is less than the time threshold.

[0077] In the above scheme, when a vehicle collision is detected, but the current working mode of the power supply system is not the low-voltage mode, and the power supply duration of the power supply system is short, the power supply system is controlled to enter the low-voltage mode. In this way, since the power supply system may be damaged when the vehicle collides, which may cause problems such as battery short circuit or battery pack leakage in the power supply system, entering the low-voltage mode can reduce the voltage and current output of the battery to ensure the safety inside the vehicle.

[0078] In some embodiments, after step S22, the vehicle control method further includes: when it is detected that the vehicle returns to normal, restoring power to the redundant system.

[0079] In some embodiments, the method of detecting that the vehicle has returned to normal may be to determine that the vehicle has returned to normal upon receiving a vehicle return to normal instruction, wherein the vehicle return to normal instruction may be an instruction issued by relevant personnel after repairing the vehicle and determining that the vehicle is safe.

[0080] In some embodiments, a method of detecting that the vehicle has returned to normal may also be to determine that the vehicle has returned to normal when the power supply system exits the low voltage mode.

[0081] In the above solution, when it is detected that the vehicle has returned to normal, the power supply to the redundant system is restored, and the power supply to the redundant system can be restored in time when the vehicle has returned to normal. This avoids the situation where the vehicle has returned to normal but the power supply has not been restored, and improves the user experience.

[0082] The embodiment of the present application can divide the functional modules of the vehicle control device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation.

[0083] like Figure 5, which is a schematic diagram of the structure of a vehicle control device 200 provided in an embodiment of the present application, wherein the vehicle control device 200 includes a determination module 201 and a processing module 202 .

[0084] The determination module 201 is used to determine the current working mode of the power supply system when a collision of the vehicle is detected; for example, the determination module 201 can be used to execute Figure 2 The processing module 202 is used to stop supplying power to the redundant system when the working mode is the low voltage mode, and provide a quick access to the emergency call system; the redundant system is a system other than the emergency call system. For example, the processing module 202 can be used to execute Figure 2 Step S22 in .

[0085] In some embodiments, the vehicle control device 200 further includes: an acquisition module 203, which is used to acquire the remaining power of the power supply system; for example, the acquisition module 203 can be used to execute Figure 3 The display module 204 is used to display the remaining time according to the remaining power. For example, the display module 204 can be used to perform Figure 3 Step S24 in .

[0086] In some embodiments, the display module 204 is specifically used to determine the usage time of the emergency call system when the remaining power is used to power the emergency call system according to the average power consumption and the remaining power of the emergency call system; determine the usage time as the remaining time; and count down and display the remaining time. Figure 4 Steps S241-S243 in .
