It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0072] Example 1

[0073] Figure 1 This is a flowchart of a system hibernation method provided in Embodiment 1 of the present invention. This embodiment is applicable to vehicle energy saving. The method can be executed by a first system, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0074] S110. In the target hibernation mode, if the second system has completed hibernation preparation, a hibernation indication signal is sent to the second system to cause the second system to start executing the process suspension operation of the second system.

[0075] The target sleep mode can be the vehicle's sentry mode. In this mode, the vehicle uses external sensors and cameras to monitor the surrounding environment in real time, intelligently identifying abnormal behavior and recording video while the vehicle is parked, while simultaneously sending alerts to the owner. The Microcontroller Unit (MCU) is the core control unit of the automotive electronic system, equivalent to the car's "brain," responsible for coordinating and managing all electronic systems such as engine control, autonomous driving assistance, and the smart cockpit.

[0076] In this embodiment, the vehicle's System-on-Chip (SoC) is a core chip integrated into the automotive electronic control system, containing two operating systems: a first system and a second system. The first system is the main control system, providing necessary functional support in the target sleep mode, while the second system requires no operation in the target sleep mode. Therefore, in the target sleep mode, the second system can be put into sleep mode to reduce power consumption. Preferably, the first system can be a Linux system, and the second system can be an Android system, where Linux is a free and open-source operating system, and Android is an open-source operating system based on Linux.

[0077] Specifically, when the vehicle is locked, the MCU detects the door closing and locking signals, triggering the SOC's sleep protocol and sending a sleep command to the first system. Upon receiving the sleep command, if the vehicle is currently in the target sleep mode, the first system can continuously send delayed sleep commands to the control unit at a set frequency. These delayed sleep commands indicate to the control unit that the first system is still operational, ensuring that pre-sleep preparations, such as data write-to-disk writes, can be completed before the second system goes into sleep mode.

[0078] In this embodiment, the hibernation preparation of the second system includes processing of various applications and services related to the second system, as well as notifying the relevant peripherals of the second system to enter a low-power state.

[0079] Specifically, the second system can notify relevant applications and services via Binder and use the UART (Universal Asynchronous Receiver / Transmitter) protocol to notify relevant peripherals to enter a low-power state. Binder is an inter-process communication mechanism that supports both IPC (Inter-Process Communication) and RPC (Remote Procedure Call), while UART is an asynchronous serial communication protocol that enables full-duplex communication and is commonly used in embedded systems and sensor modules. In the second system, relevant applications and services can request CPU locks for power management to complete their pre-sleep processing, such as saving data and terminating unnecessary processes. Once all applications and services release the locks, it indicates that all tasks have been properly handled, and the second system is ready to sleep. The first system can coordinate with the second system via RPC and the Binder mechanism to confirm whether the second system has completed its sleep preparation. RPC is a communication protocol that allows different processes to call each other's methods; the client sends parameters to the server, and the server executes the parameters and returns the result.

[0080] Furthermore, if the second system has completed its hibernation preparation, the first system can send a hibernation indication signal to the second system to cause the second system to begin executing the process suspension operation of the second system.

[0081] Specifically, the first system can send a hibernation indication signal to the second system, and the second system responds to the signal by starting a process suspension operation (Suspend to RAM, STR), thereby achieving a hibernation state.

[0082] S120, Confirm that the second system has entered hibernation mode.

[0083] In this embodiment, after the second system begins executing STR, the first system can send STR start information to the control unit. When the second system completes STR execution, it notifies the first system that STR has ended. Upon receiving the STR end signal from the second system, the first system confirms that the second system has entered a sleep state and sends the STR end signal back to the control unit. Thus, the sleep operation of the second system is complete.

[0084] The system hibernation method disclosed in this invention first, in the target hibernation mode, if the second system has completed hibernation preparation, sends a hibernation indication signal to the second system, causing the second system to begin executing the process suspension operation; finally, it confirms that the second system has entered hibernation state. The system hibernation method disclosed in this invention, by hibernating the second system in the target hibernation mode, can reduce processing load and energy consumption, reduce unnecessary data interaction, and thus extend battery life.

[0085] Example 2

[0086] Figure 2 This is a flowchart of a system hibernation method provided in Embodiment 2 of the present invention. This embodiment is a refinement of the above embodiment, such as... Figure 2 As shown, the method includes:

[0087] S210. In the target hibernation mode, if the second system has completed hibernation preparation, a hibernation indication signal is sent to the second system to cause the second system to start executing the process suspension operation of the second system.

[0088] In this embodiment, when the vehicle is locked, the control unit (MCU) detects the door closing and locking signals and sends a hibernation command to the first system. Upon receiving the hibernation command, if the vehicle is currently in the target hibernation mode, the first system can continuously send delayed hibernation commands to the control unit at a set frequency. These delayed hibernation commands indicate to the control unit that the first system is still operational, ensuring that pre-hibernation preparations, such as data write-to-disk writes, can be completed before the second system goes into hibernation.

[0089] Preferably, the target hibernation mode is the vehicle's sentry mode, with the first system being a Linux system and the second system being an Android system. The Linux system comprises three modules: Linux APP / service, Linux native power, and Linux power service. The Linux APP / service primarily manages the lifecycle of background daemons and provides system- or application-level services; Linux native power manages power states at the kernel level, controlling hardware power consumption and sleep states; and the Linux power service primarily provides power state monitoring, policy settings, and advanced energy consumption analysis. In sentry mode, the Linux APP / service requests the Linux power service to hibernate the Android system. If the Linux power service receives a hibernation command from the control unit, it sends delayed hibernation commands to the control unit at a set frequency.

[0090] In this embodiment, the second system performs a hibernation preparation operation in response to the notification to enable the target hibernation mode.

[0091] Optionally, the method for performing the hibernation preparation operation may be: controlling the target application and target service corresponding to the second system to perform at least one of the following operations: requesting a CPU lock, releasing a CPU lock, saving target data, and terminating the target process; and / or controlling the target peripheral device corresponding to the second system to enter a low-power state.

[0092] Specifically, before entering hibernation, the second system needs to notify its peripherals to enter a low-power state and also instruct its applications and services to prepare for hibernation. These applications and services can request CPU locks for power management to complete their pre-hibernation processing, such as saving data and terminating unnecessary processes. Once all applications and services release the locks, it indicates that all tasks have been properly handled and the second system is ready to hibernate. If the second system is ready to hibernate, the first system can send a hibernation indication signal to the second system, causing it to begin suspending its processes.

[0093] Preferably, the second system can be an Android system. The Android system includes two modules: Android powerservice and Android native power. Android powerservice, as a system-level service, is responsible for coordinating power behavior between applications and hardware; Android native power is responsible for performing hardware operations at the lower level. After all services in the Android system release the CPU lock, Android powerservice sends a signal indicating that all services have released the CPU lock to Linux power service, notifying the Linux system that it is ready to hibernate. Then, Linux power service sends a hibernation indication signal to Android power service, triggering the Android system's process suspension (STR) operation to begin. Simultaneously, Linux power service sends Android STR start information to Linux native power, which then sends this information to the MCU.

[0094] S220. If a process suspension termination signal is received from the second system, it is confirmed that the second system has entered a hibernation state.

[0095] In this embodiment, when the second system finishes executing the STR, the second system notifies the first system that the STR has ended. Upon receiving the STR end signal from the second system, the first system confirms that the second system has entered a sleep state and feeds back the STR end signal to the control unit.

[0096] Specifically, when the Android system STR finishes execution, the Android native power sends the Android STR completion information to the Linux native power. The Linux native power then sends this information to the MCU and notifies the Linux power service that the Android STR has ended.

[0097] Furthermore, if a wake-up command from the control unit is received before the process suspension end signal sent by the second system is received, the wake-up command is recorded, and the second system is woken up after the second system completes the process suspension operation.

[0098] Specifically, the Android system cannot be interrupted when executing STR. If the MCU notifies the wake-up before the Android STR ends, the wake-up instruction is recorded first, and the wake-up is performed after the Android STR ends.

[0099] Optionally, the method for waking up the second system may be: in response to the wake-up command of the control unit, sending a wake-up signal to the second system.

[0100] Figure 3 This is a wake-up flowchart of a second system provided in an embodiment of the present invention. As shown in the figure, when the first system is working and the second system is in sleep mode, if the control unit (MCU) detects an external wake-up source such as a user approaching the vehicle or a door opening signal, it can send a wake-up command to the first system and transmit the reason for the external wake-up to the first system. After responding to the wake-up command, the first system executes the wake-up program and sends a wake-up signal to the second system. If the second system wakes up successfully, it notifies the first system that the second system has been successfully woken up.

[0101] Furthermore, after confirming that the second system has entered a hibernation state, the hibernation state of the second system can also be fed back to the control unit.

[0102] Furthermore, after feeding back the hibernation status of the second system to the control unit, the following can also be done: if the target hibernation mode is exited, then the hibernation operation of the first system is executed.

[0103] Specifically, once the second system goes into hibernation, if the target hibernation mode exits, the current vehicle no longer needs the support of the first system, and the first system can also begin hibernation.

[0104] Optionally, the method for performing the hibernation operation of the first system may be: performing a hibernation preparation operation of the first system; if the hibernation preparation has been completed, then starting the process suspension operation of the first system and sending a process suspension start signal to the control unit; if the process suspension operation of the first system has been completed, then sending a process suspension end signal to the control unit and stopping sending delayed hibernation commands.

[0105] Specifically, the target hibernation mode can be sentinel mode, and the primary system can be a Linux system. When sentinel mode exits, the Linux application / service notifies the Linux power service that sentinel mode has exited. All Linux system-related services can then request CPU locks for power management to complete their pre-hibernation processing, such as saving data and terminating unnecessary processes. Once all services release the locks, it indicates that all tasks have been properly handled, and the Linux system is ready for hibernation. After hibernation preparation is complete, the Linux power service triggers the Linux system's Process Suspension Operation (STR) to begin. The Linux native power sends the Linux STR start information to the MCU. When the Linux STR ends, the Linux native power notifies the MCU that the Linux STR has ended. The Linux system completes hibernation and stops sending delayed hibernation commands.

[0106] Furthermore, after the process suspension operation begins, it can also: if a wake-up command is received from the control unit, record the wake-up command, and wait for the first system to complete the process suspension operation before waking up the first system.

[0107] Specifically, the Linux system cannot be interrupted when executing STR. If the MCU notifies the system to wake up before the Linux STR ends, the wake-up command will be recorded first, and the system will be woken up after the Linux STR ends.

[0108] Furthermore, the system hibernation method also includes: in the target hibernation mode, in response to the hibernation command of the control unit, sending a delayed hibernation command to the control unit at a set frequency; wherein the delayed hibernation command is used to feed back the working status of the first system to the control unit.

[0109] Specifically, after the control unit sends a hibernation command to the first system, the first system responds by sending a delayed hibernation command to the control unit. The delayed hibernation command notifies the control unit that the first system is still operational, ensuring that the second system can complete some data write-to-disk tasks before entering hibernation, until the first system finishes hibernation and stops sending delayed hibernation commands. Preferably, the delayed hibernation command can be sent by starting a Postpone (delayed hibernation) timer. This timer allows sufficient cleanup time for critical services, preventing data loss or abnormal termination.

[0110] Figure 4This is a schematic diagram of a system hibernation process provided by an embodiment of the present invention. As shown in the figure, the first system is a Linux system, and the second system is an Android system. After the sentinel mode is enabled, the Linux APP / service requests the Linux power service to hibernate the Android system. The Linux power service responds to the hibernation command from the control unit (MCU) and sends a delayed hibernation command to the control unit. After the Android power service completes hibernation preparation, it sends a signal to the Linux power service that all services have released the CPU lock. The Linux power service sends a hibernation indication signal to the Android power service, triggering the start of the Android system's process suspension operation (STR). At the same time, the Linux power service sends the Android STR start information to the Linux native power, and the Linux native power sends this information to the MCU. The Android native power notifies the Linux native power that the Android STR has ended, and the Linux native power sends this information to the MCU and notifies the Linux power service that the Android STR has ended. When the sentinel mode is exited, the Linux APP / service notifies the Linux power service that the sentinel mode has exited, and the Linux system performs hibernation preparation. When all services release the CPU lock, it indicates that all tasks have been properly handled, and the Linux system has completed hibernation preparation. The Linux power service triggers the start of the Linux system's Process Suspension Operation (STR). The Linux native power sends the start information of the Linux STR to the MCU. When the Linux STR ends, the Linux native power notifies the MCU that the Linux STR has ended. The Linux system then completes hibernation and stops sending delayed hibernation commands.

[0111] The system hibernation method disclosed in this invention can reduce processing load and energy consumption, reduce unnecessary data interaction, and thus extend battery life by hibernating the second system in the target hibernation mode.

[0114] The second system process suspension module 310 is used to send a hibernation indication signal to the second system when the second system has completed hibernation preparation in the target hibernation mode, so that the second system can start to execute the process suspension operation of the second system.

[0115] The hibernation state confirmation module 320 is used to confirm that the second system has entered hibernation state.
