[0033] It should be noted that due to space limitations, this specification does not exhaust all optional implementation manners. After reading this specification, those skilled in the art should be able to think that as long as the technical features do not conflict with each other, any combination of technical features can constitute an optional implementation manner. The following will explain each embodiment in detail.

[0034] In the field of electric vehicles, the development trend is that the sizes of the instrument panel screen, the central control screen, and the co-pilot screen are getting larger and larger, and high-configured vehicles also need to support functions such as AR-HUD (Augmented Reality-Head Up Display). The degree of intelligence of the cockpit is also getting higher and higher, and more and more functions are carried, which also places very high requirements on the performance of the vehicle. With the rapid development of cockpit processing chips, it has become a reality to drive multiple screens with one device. However, in order to improve the user experience, it is necessary to increase the chip computing power to meet the performance requirements.

[0035] The increase in computing power will inevitably bring more power consumption. In the relevant regulations of the electric vehicle industry, if the small battery of the electric vehicle is cut off, an emergency small battery is required to supply power to the vehicle to make the vehicle continue to work for 10 minutes. However, it is very difficult for the emergency small battery to meet the large power consumption requirements. When the small battery is cut off due to a vehicle collision, because the load during system operation is large and the output capacity of the emergency small battery does not match the load of the system, when the system switches to the emergency small battery for power supply, the system completely loses power within 100 ms to 200 ms, thus not meeting the relevant regulations. Therefore, when the small battery is cut off, it is necessary to control various application services on the vehicle to increase the working time of the vehicle under low power consumption.

[0036] A control method, device, and equipment for application services on a vehicle based on low power consumption provided by the present invention aim to solve the above technical problems in the prior art.

[0037] The technical solution of the present invention and how the technical solution of the present invention solves the above technical problems will be described in detail below with specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0038] Figure 1 is a schematic flowchart of a control method for application services on a vehicle based on low power consumption provided by an embodiment of the present invention. This method can be executed by a control device for application services on a vehicle based on low power consumption. This method is applied to a vehicle, and a small battery and an SOC are configured on the vehicle. The small battery is used to supply power to the vehicle, and the small battery and the SOC are connected by a hard wire. At least a first operating system and a second operating system are deployed in the vehicle. As Figure 1 shown, this method includes the following steps:

[0039] S101. If the current voltage value of the small battery is less than a preset voltage threshold, send a low-level signal to the SOC on the vehicle through the hard wire; wherein, a board support package of the first operating system is deployed in the SOC.

[0040] Exemplarily, a small battery can be installed on a vehicle of an electric vehicle. The small battery can be used as a vehicle battery to supply power to the vehicle, enabling the vehicle to provide various application services for users. For example, it can supply power to devices such as cameras and intelligent seats on the vehicle, and can also supply power to system functions such as a driver monitoring system and a passenger monitoring system. Problems may occur with the small battery on the vehicle, resulting in the power supply being cut off. For example, a vehicle collision may cut off the small battery. An emergency small battery can also be installed on the vehicle. If it is detected that the small battery is cut off or has a continuous low voltage, power can be supplied through the emergency small battery. In order for the vehicle to continue to operate for 10 minutes when the external power supply is cut off, the vehicle needs to be in a low-power state, that is, control some external devices and application services to be turned off to reduce unnecessary power consumption. In this embodiment, the external devices of the vehicle can be simply referred to as peripherals.

[0041] An SOC (System on Chip) can be installed on the vehicle. To reduce costs, it can be a single SOC. The SOC and the small battery can be connected by a hard wire, so as to be able to sense the voltage signal of the small battery. A hardware for voltage detection can also be connected between the SOC and the small battery. This hardware can continuously monitor the voltage of the small battery. If the voltage of the small battery is lower than a preset voltage threshold, a low-level signal can be output to the SOC. For example, if the preset voltage threshold is 6V, when the voltage of the small battery drops to 6V, a low-level signal is sent to one end of the SOC on the vehicle.

[0042] Multiple operating systems can be deployed on the vehicle. For example, a dual-system is deployed on the vehicle, namely a Linux system and an Android system. The Linux system can be deployed on the instrument side, and the Android system can be deployed on the center console side. In this embodiment, the first operating system can be the Android system, and the second operating system can be the Linux system. A board support package of the first operating system can be deployed in the SOC end, that is, the SOC can include an Android BSP (Board Support Package). Sending a low-level signal to the SOC end is also sending a low-level signal to the Android BSP.

[0043] S102. According to the low-level signal, through the board support package of the first operating system, send low-power signals to the first operating system and the second operating system respectively; wherein, the low-power signal represents that the vehicle is currently in a low-level state, and the low-power signal is used to indicate a mode switch for the application services on the vehicle.

[0044] Exemplarily, after receiving a low-level signal, the Android BSP can send low-power signals to the Android system and the Linux system respectively, that is, inform the two operating systems that the vehicle needs to be in a low-power state, and realize the unified control of the dual systems by the BSP.

[0045] The low-power signal can be a preset signal, indicating that the small battery of the vehicle is currently at a low level. As long as the Android BSP receives the low-level signal, it can synchronously send the preset low-power signal to the dual systems. It can also generate a low-power signal according to the low-level signal. For example, the low-power signal can include the current voltage value of the small battery. Then, the low-power signal containing the voltage value is synchronously sent to the dual systems.

[0046] The low-power signal is used to instruct the operating system to perform mode switching on the application services on the vehicle, so that the application services on the vehicle are in a low-power state. For example, after receiving the low-power signal, the operating system can turn off some peripherals on the vehicle, and the peripherals turned off by different operating systems can be different.

[0047] S103. Control the first application service on the vehicle to switch to a preset sleep mode through the first operating system, and control the second application service on the vehicle to switch to a preset sleep mode through the second operating system; wherein, the sleep mode is used to prohibit the application service from self-starting.

[0048] Exemplarily, different operating systems can control different application services. The application services that the first operating system can control are preset as the first application service, and the application services that the second operating system can control are preset as the second application service. For example, the first application service is the related service of the automatic driving function on the central control side, and the second application service is the related service of the instrument display function on the instrument side.

[0049] The sleep mode of the application service is preset. The sleep mode means that the application service does not work and prohibits the application service from self-starting. After receiving the low-power signal, the first operating system can switch the first application service to the sleep mode, that is, prohibit the first application service from self-starting. At the same time, after receiving the low-power signal, the second operating system can switch the second application service to the sleep mode, that is, prohibit the second application service from self-starting.

[0050] In this embodiment, the dual systems are uniformly controlled by the BSP, and the dual systems simultaneously perform optimization of the internal application services, realizing that when the small battery of the vehicle is abnormally cut off, the overall power consumption of the dual systems is reduced within an extremely short time, and the delay time is less than 100 ms, meeting the output capacity of the emergency small battery.

[0051] An embodiment of the present invention provides a control method for application services on a vehicle based on low power consumption, which can monitor the voltage of the small battery in the vehicle in real time and determine whether the small battery is in a low-level state. If the current voltage value of the small battery is less than the preset voltage threshold, it indicates that it is currently in a low-level state, and a low-level signal can be sent to the SOC terminal on the vehicle through a hard wire. A board support package of the first operating system is deployed in the SOC terminal. After receiving the low-level signal, the SOC terminal can, through the board support package of the first operating system, synchronously send a low-power signal to the first operating system and the second operating system, thereby informing the two operating systems that the application services need to be controlled currently to meet the power supply requirements of the vehicle. Through the first operating system, the first application service on the vehicle can be switched to the sleep mode, and through the second operating system, the second application service on the vehicle can be switched to a preset sleep mode, and the first application service and the second application service are prohibited from self-starting. By synchronously controlling multiple systems, the power consumption of each system can be reduced within a very short time, the delay of application service control can be reduced, the output capacity of the emergency small battery can be met, and the normal driving time of the vehicle can be increased.

[0052] Figure 2 FIG. is a schematic flow chart of a control method for application services on a vehicle based on low power consumption provided by an embodiment of the present invention. This embodiment is an alternative embodiment based on the above embodiment.

[0053] In this embodiment, corresponding power management modules are deployed in both the first operating system and the second operating system. The power management module is used to adjust the power consumption of the application services; according to the low-level signal, through the board support package of the first operating system, sending low-power signals to the first operating system and the second operating system respectively includes: generating a low-power signal according to the low-level signal; wherein, the low-level signal is a hard signal and the low-power signal is a soft signal; through the board support package of the first operating system, inputting the low-power signal into the power management module in the first operating system and the power management module in the second operating system.

[0054] As Figure 2 shown, the method includes the following steps:

[0055] S201. If the current voltage value of the small battery is less than the preset voltage threshold, send a low-level signal to the SOC on the vehicle through a hard wire; wherein, a board support package of the first operating system is deployed in the SOC.

[0056] Exemplarily, this step can refer to the above step S101 and will not be elaborated.

[0057] S202. Generate a low-power signal according to the low-level signal; wherein, the low-level signal is a hard signal and the low-power signal is a soft signal.

[0058] Exemplarily, the low-level signal is a signal transmitted through hardwiring and belongs to a hard signal, while the low-power signal belongs to a soft signal. That is, after receiving the hard signal, the Android BSP can convert the hard signal into a soft signal and send the soft signal to the two operating systems.

[0059] A mapping rule from hard signal to soft signal can be preset in the Android BSP to map the low-level signal to a low-power signal. In this embodiment, the preset mapping rule is not specifically limited. For example, if the low-level signal contains the voltage value of a small battery, the specific voltage value can be converted into binary form, and the binary data is used as the low-power signal.

[0060] S203: Input the low-power signal into the power management module in the first operating system and the power management module in the second operating system through the board support package of the first operating system.

[0061] Exemplarily, corresponding power management modules are deployed in both the first operating system and the second operating system. For example, the power management module in the Android system is called Native Core Power, and the power management module in the Linux system is called Power Manager. The Android BSP can send the soft signal to different operating systems, that is, the low-power signal can be input into Native Core Power of the Android system and Power Manager of the Linux system.

[0062] In this embodiment, inputting the low-power signal into the power management module in the second operating system through the board support package of the first operating system includes: inputting the low-power signal into a preset virtualization software layer through the board support package of the first operating system to obtain a virtualized signal corresponding to the low-power signal; wherein the preset virtualization software layer is used to convert the low-power signal into a signal format adapted to the second operating system; and inputting the virtualized signal into the power management module in the second operating system.

[0063] Specifically, the BSP and Native Core Power both belong to the Android system, that is, the first operating system. The low-power signal of the BSP can be directly read by Native Core Power. That is, the Android BSP can directly send the low-power signal to the power management module of the first operating system.

[0064] For the second operating system, since it belongs to a different operating system from the BSP, the BSP needs to map the low-level signal into two different types of soft signals. One is the low-power signal, which is directly sent to the first operating system. The other needs to perform format conversion on the low-power signal and send the converted low-power signal to the second operating system.

[0065] A virtualization software layer is preset. For example, the virtualization software layer can adopt TTI Hypervisor. TTI Hypervisor is a virtualization technology commonly used in embedded systems, focusing on safety and real-time applications in the automotive industry. TTI Hypervisor allows multiple operating system instances or applications to run on the same hardware platform while ensuring isolation and security between them. After receiving the low-level signal, the Android BSP first converts the low-level signal into the form of a soft signal, that is, the low-power signal that the Android system can read, and then performs format conversion on the low-power signal through the virtualization software layer to obtain a virtualized signal. That is, the virtualized signal and the low-power signal are two types of soft signals, both of which can indicate a mode switch for the application services on the vehicle. The virtualized signal is adapted to the Linux system and can be read by the power management module of the Linux system. In this embodiment, the virtualization process is not specifically limited.

[0066] The beneficial effect of this setting is that format conversion processing is performed on the initial soft signal, that is, the low-power signal, so that the soft signal can be read by the Linux system, enabling the dual systems to synchronously control the application services and improving the feasibility and efficiency of the application service control.

[0067] S204: Through the first operating system, control the first application service on the vehicle to switch to a preset sleep mode, and through the second operating system, control the second application service on the vehicle to switch to a preset sleep mode; wherein, the sleep mode is used to prohibit the application service from self-starting.

[0068] Exemplarily, this step can refer to the above step S103 and will not be elaborated here.

[0069] An embodiment of the present invention provides a control method for vehicle application services based on low power consumption, which can monitor the voltage of the small battery in the vehicle in real time to determine whether the small battery is in a low voltage state. If the current voltage value of the small battery is less than the preset voltage threshold, it indicates that the current is in a low voltage state, and a low voltage signal can be sent to the SOC terminal on the vehicle through a hard wire. A board support package of the first operating system is deployed in the SOC terminal. After receiving the low voltage signal, the SOC terminal can synchronously send a low power consumption signal to the first operating system and the second operating system through the board support package of the first operating system, so as to inform the two operating systems that the application services need to be controlled currently to meet the power supply requirements of the vehicle. Through the first operating system, the first application service on the vehicle can be switched to the sleep mode, and through the second operating system, the second application service on the vehicle can be switched to a preset sleep mode, and the first application service and the second application service are prohibited from starting automatically. By synchronously controlling multiple systems, the power consumption of each system can be reduced within a very short time, the delay of application service control can be reduced, the output capacity of the emergency small battery can be met, and the normal driving time of the vehicle can be increased.

[0070] Figure 3 FIG. is a schematic flowchart of a control method for vehicle application services based on low power consumption provided by an embodiment of the present invention. This embodiment is an optional embodiment based on the above embodiment.

[0071] In this embodiment, the first application service includes at least one of a driver monitoring service, a passenger monitoring service, and a panoramic service; controlling the first application service on the vehicle to be switched to a preset shutdown mode through the first operating system includes: performing a shutdown operation on the first application service on the vehicle through the first operating system, and switching the first application service on the vehicle to a preset sleep mode.

[0072] The second application service includes a head-up display service; controlling the second application service on the vehicle to be switched to a preset sleep mode through the second operating system includes: performing a shutdown operation on the second application service on the vehicle through the second operating system, and switching the second application service on the vehicle to a preset sleep mode.

[0073] As Figure 3 shown, the method includes the following steps:

[0074] S301. If the current voltage value of the small battery is less than the preset voltage threshold, send a low voltage signal to the SOC on the vehicle through a hard wire; wherein, a board support package of the first operating system is deployed in the SOC.

[0075] Exemplarily, this step can refer to the above step S101 and will not be elaborated.

[0076] S302. According to the low-level signal, through the board support package of the first operating system, send low-power signals to the first operating system and the second operating system respectively; wherein, the low-power signal characterizes that the vehicle is currently in a low-level state, and the low-power signal is used to indicate to perform a mode switch on the application services on the vehicle.

[0077] Exemplarily, this step can refer to the above step S102 and will not be elaborated here.

[0078] S303. Through the first operating system, perform a shutdown operation on the first application service on the vehicle and switch the first application service on the vehicle to a preset sleep mode.

[0079] Exemplarily, the first application services corresponding to the Android system may include services such as DMS (Driver Monitor System), OMS (Occupancy Monitoring System), IMS (In-cabin monitoring System), and EVS (Enhanced Vision System). Through the Android system, the above application services can be controlled to switch to the sleep mode, thereby prohibiting the above application services from automatically starting in the low-power state of the vehicle.

[0080] Before switching the first application service to the sleep mode, it can first be determined whether the first application service is in a running state. If not, it can be directly switched to the sleep mode; if it is in a running state, the first application service can be forcibly stopped, that is, a shutdown operation is performed on the first application service, and then the first application service is switched to the sleep mode. For example, services such as DMS, IMS, and EVS can be actively and forcibly stopped and prohibited from automatically starting. Operations such as shutdown and mode switching on the first application service can be performed through NativeCore Power in the Android system.

[0081] In this embodiment, the method further includes: stopping the user mode of the first operating system through the first operating system.

[0082] Specifically, after receiving the low-power signal, the first operating system can also perform an operation to stop the user mode. The user mode is one of the modes in a computer operating system for running application programs, and it is opposite to the kernel mode, which is the mode in which the operating system kernel runs. The division of the user mode and the kernel mode is an important protection mechanism in modern operating systems, aiming to improve the stability and security of the system.

[0083] The first operating system is the Android system, that is, the Android user state can be stopped. On the Android side, through Native Core Power in the Native Framework layer, a low-power signal can be sent to the Power Manager Service in the Java Framework layer, and the Power Manager Service in the Java Framework layer executes to stop the Android user state. Native Framework and Java Framework belong to the architecture of the Android system, and both Native Core Power and Power Manager Service are open-source modules in the Android system.

[0084] The beneficial effect of such a setting is to forcibly stop the Android user state, further reduce the load, and change the self-exit of the user-state applications to be uniformly controlled by the power management service in the Android system. The power consumption of the Android system can be reduced within 80 - 90 ms, and the running time of the vehicle under low power consumption can be increased.

[0085] S304. Through the second operating system, perform a shutdown operation on the second application service on the vehicle and switch the second application service on the vehicle to a preset sleep mode.

[0086] Exemplarily, the second application system corresponding to the Linux system may include services such as HUD (Head Up Display). Through the Linux system, the above application services can be controlled to switch to the sleep mode, thereby prohibiting the above application services from automatically starting in the low-power state of the vehicle.

[0087] Before switching the second application service to the sleep mode, it can be first determined whether the second application service is in the running state. If not, it can be directly switched to the sleep mode; if it is in the running state, the second application service can be forcibly stopped, that is, a shutdown operation is performed on the second application service, and then the second application service is switched to the sleep mode. For example, services such as HUD can be actively and forcibly stopped and prohibited from automatically starting. The Linux system's Power Manager can be used to perform operations such as shutting down and mode switching on the second application service.

[0088] In this embodiment, the method further includes: setting a timer with a preset time length through a second operating system, and monitoring the current timing length of the timer; if the current timing length reaches the preset time length, adjusting the operating frequency of a preset component in the vehicle; where the preset component includes at least one of a CPU, a GPU, and a DDR.

[0089] Specifically, after receiving a virtualization signal, the Power Manager in the Linux system can also start the SOC main frequency control service, which is used to control the operating frequency of the preset component. The SOC main frequency control service means setting a timer, and when the timer reaches a certain time, the operating frequency of the preset component can be adjusted. The preset component can include a CPU (Central Processing Unit, central processor), a GPU (Graphics Processing Unit, graphics processor), a DDR (Double Data Rate Synchronous Dynamic Random Access Memory, double data rate memory), etc., that is, the operating frequencies of the CPU, GPU, DDR, etc. can be adjusted.

[0090] Set the time length of the timer. For example, the preset time length is 200 ms. Monitor the current timing length of the timer in real time, that is, the timer records how long it has been timed currently. If the current timing length reaches the preset time length, for example, the timer records that 200 ms has timed out, the operating frequency of the preset component in the vehicle can be adjusted. For example, the operating frequencies of the CPU, DDR, and GPU can be reduced to the preset lowest gear.

[0091] The beneficial effect of such a setting is that by reducing the operating frequencies of the CPU, DDR, and GPU to the lowest gear, the power consumption can be further reduced. By setting the timer, the operating frequency of the preset component can be adjusted after the peripheral device and the application service stop, avoiding the peripheral device and the application service from freezing or having other failures due to directly reducing the operating frequency of the preset component, and ensuring that the power consumption of the vehicle can be reduced after the preset time length, improving the control effectiveness of the peripheral device and the application service on the vehicle.

[0092] In this embodiment, the execution order of S303 and S304 is not specifically limited.

[0093] In this embodiment, the method further includes: controlling a preset first external device on the vehicle to perform a shutdown operation through a board support package of the first operating system.

[0094] Specifically, after receiving a low-level signal, the Android BSP can control multiple peripherals on the vehicle, and the peripherals that the Android BSP can control are regarded as the first external devices. Which first external devices are preset, for example, the first external devices may include USB charging enable, camera power supply enable, panoramic camera, etc. The first external devices may include hardware peripherals on the Android system side or hardware peripherals on the Linux system side.

[0095] The hardware peripherals on both sides of the dual system are uniformly controlled by the Android BSP for forced shutdown, that is, the first external devices on the vehicle are controlled to perform shutdown operations simultaneously.

[0096] The beneficial effect of such a setting is that the hardware peripherals on both sides of the dual system are uniformly controlled, reducing the delay of peripheral control. The peripheral control delay time is less than 100 ms, improving the control efficiency of the vehicle.

[0097] In this embodiment, a micro control unit MCU is configured on the vehicle; the method further includes: if the current voltage value of the small battery is less than a preset voltage threshold, a low-level signal is sent to the MCU on the vehicle; if the MCU responds to the low-level signal, the preset second external device on the vehicle is controlled to perform a shutdown operation.

[0098] Specifically, an MCU (MicroControl Unit) can be configured on the vehicle. The MCU and the small battery can be connected by a hard wire, and a hardware for voltage detection can also be connected between the MCU and the small battery. If it is detected that the voltage of the small battery is lower than the preset voltage threshold, a low-level signal can be output to the SOC and the MCU at the same time. For example, after a collision occurs to the small battery on the vehicle, the voltage drops to 6V, and the hardware end detects a low level and outputs the low-level signal to the SOC and the MCU.

[0099] The MCU can control multiple peripherals on the vehicle, and the peripherals that the MCU can control are regarded as the second external devices. Which second external devices are preset, for example, the second external devices may include a main power amplifier STB (Set-Top Box), a secondary power amplifier STB, etc. After the MCU end detects the input of a hard signal, that is, a low-level signal, it performs an operation to turn off the second external device.

[0100] The beneficial effect of such a setting is that the MCU end and the SOC end can synchronously control the vehicle, and the MCU end controls the second peripheral to turn off. At the same time, the SOC end controls the first peripheral to turn off and maps the hard signal to a soft signal and sends it to the dual system. It effectively reduces the delay of vehicle control and increases the running time of the vehicle under low power consumption.

[0101] Figure 4 Schematic diagram of the vehicle control process under low level. When it is detected that the small battery is at a low level, the low-level signal can be synchronously sent to the MCU and the SOC, that is, sent to the MCU and the Android BSP. The MCU controls the second external device to turn off, and the Android BSP controls the first external device to turn off. The Android BSP can also convert the low-level signal into a low-power signal, send it to the Native Core Power of the Android system, and virtualize the low-power signal to obtain a virtualized signal, and send the virtualized signal to the Power Manager of the Linux system. Among them, the Native Core Power of the Android system is the power management module of the Android system, and the Power Manager of the Linux system is the power management module in the Linux system. The Native Core Power of the Android system stops the Android user state through the Power ManagerService. The Native Core Power of the Android system can also stop the first application service and prohibit its self-start. The Power Manager of the Linux system stops the second application service and prohibits its self-start, and at the same time sets a timer to reduce the working frequency of the preset component to the lowest gear.

[0102] An embodiment of the present invention provides a control method for application services on a vehicle based on low power consumption, which can monitor the voltage of the small battery in the vehicle in real time and determine whether the small battery is in a low-level state. If the current voltage value of the small battery is less than the preset voltage threshold, it means that it is currently in a low-level state, and a low-level signal can be sent to the SOC end on the vehicle through a hard wire. The board support package of the first operating system is deployed at the SOC end. After receiving the low-level signal, the SOC end can synchronously send a low-power signal to the first operating system and the second operating system through the board support package of the first operating system, so as to inform the two operating systems that the application services need to be controlled currently to meet the power supply requirements of the vehicle. Through the first operating system, the first application service on the vehicle can be switched to the sleep mode, and through the second operating system, the second application service on the vehicle can be switched to the preset sleep mode, and the first application service and the second application service are prohibited from self-starting. By synchronously controlling multiple systems, the power consumption of each system can be reduced within a very short time, the delay of application service control can be reduced, the output capacity of the emergency small battery can be met, and the normal driving time of the vehicle can be increased.
