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

[0047] See also Figure 1 , Figure 1 A flowchart of a vehicle power consumption control method provided in an embodiment of the present application.

[0048] A vehicle power consumption control method provided in an embodiment of the present application is applied to an electronic control unit (ECU) of a vehicle and may include the following steps:

[0049] Step S101: Detect whether the vehicle triggers the vehicle emergency call system.

[0050] Step S102: In response to the vehicle triggering the on-board emergency call system, the vehicle's on-chip integrated system is controlled to enter a set low power consumption state; wherein the on-chip integrated system is equipped with a target domain based on virtual machine hypervisor fusion, and the target domain includes a domain in the electronic and electrical architecture; the set low power consumption state includes a state in which other functional modules except the emergency call functional module and the preset functional module are turned off.

[0051] In practical applications, with the evolution of highly integrated and powerful system on chip (SOC), and the gradual development of vehicle electronic and electrical architecture (EE) from traditional distributed design to centralized design, the domains in the vehicle electronic and electrical architecture can be integrated into the SOC through the hypervisor, such as integrating the vehicle cockpit domain and the connected domain Tbox (Telematics BOX, intelligent vehicle terminal of the Internet of Vehicles system), or integrating the vehicle cockpit domain, the connected domain Tbox, and the ADAS (Advanced Driving Assistance System) domain. Although the vehicle layout is simplified, when the vehicle triggers the emergency call service, the complex business functions of the SOC will consume more power of the vehicle, making it difficult for the vehicle to support the emergency call service, thereby shortening the rescue time and increasing driving risks. To this end, when the electronic control unit of the present application detects that the vehicle triggers the on-board emergency call system (Emergency Call, Ecall), it controls the vehicle's on-chip integrated system to enter a set low-power state, that is, controls other functional modules in the on-chip integrated system except the emergency call functional module and the preset functional module to enter a shutdown state, so as to minimize the power consumption of the on-chip integrated system while ensuring the emergency call function and preset function of the on-chip integrated system, so that the vehicle can perform emergency call services for a longer period of time.

[0052] It should be noted that the types of other functional modules except the emergency call function module and the preset function module can be determined according to the type of domain integrated based on the virtual machine hypervisor on the integrated system on chip, and the emergency call function module refers to the module that supports the vehicle to perform emergency call services, such as GNSS (Global Navigation Satellite System) module, voice call function module, GPS (Global Positioning System) module, AMP (Amplifier), microphone, etc.; the preset function module refers to the module that is set to maintain the corresponding function of the vehicle, which can be customized by the user or set as a module to maintain the basic function of the vehicle. In addition, the vehicle triggering the emergency call system can be the emergency call system triggered after the vehicle collides, or the emergency call system can be triggered after the SOS (vehicle self-help rescue system) button on the vehicle is pressed, etc. In any case, the electronic control unit can detect that the vehicle triggers the emergency call system through the information generated after the emergency call system is triggered.

[0053] In specific application scenarios, the vehicle power consumption management method of the present application can be specifically applied to the MCU (Microcontroller Unit) in the vehicle body ECU, and in the process of controlling the vehicle's on-chip integrated system to enter a set low-power state, the power supply of other functional modules in the on-chip integrated system except the emergency call function module and the preset function module can be directly cut off, or instructions can be sent to the on-chip integrated system to make other functional modules in the on-chip integrated system except the emergency call function module and the preset function module enter a shutdown state, etc.

[0054] In a specific application scenario, after the domains in the vehicle's electronic and electrical architecture are integrated into the on-chip integrated system through a virtual machine hypervisor, a corresponding virtual machine manager (VM) will be set up in the on-chip integrated system to perform corresponding business management, that is, the virtual machine manager can identify and shut down other functional modules managed by itself except the emergency call functional module and the preset functional module. Therefore, when the electronic control unit controls the vehicle's on-chip integrated system to enter a set low-power state through instructions, it can send notification instructions to each virtual machine manager of the on-chip integrated system in turn, indicating that the vehicle has triggered the on-board emergency call system; it can also first send a notification instruction to a virtual machine manager of the on-chip integrated system, and then the virtual machine manager sends a notification instruction to other virtual machine managers, for example, the virtual machine manager sends a notification instruction to other virtual machine managers through an IPC (inter-process communication) communication mechanism between VMs, etc.; so that all virtual machine managers of the on-chip integrated system can enter the set low-power state after responding to the notification instruction.

[0055] Optionally, the electronic control unit may first send a notification instruction to the target virtual machine manager of the on-chip integrated system through the first communication link, the notification instruction including an instruction indicating that the vehicle triggers the on-board emergency call system; detect whether a response message sent by the target virtual machine manager is received, the response information including information indicating that the notification instruction has been received; in response to not receiving the response message, send a notification instruction to the target virtual machine manager through the second communication link, and return to execute the step of detecting whether the response message sent by the target virtual machine manager is received. The types of the first communication link and the second communication link can be flexibly adjusted according to actual needs. For example, the first communication link may be spi (Serial Peripheral Interface) or uart (Universal Asynchronous Receiver / Transmitter), and the second communication link may be gpio (General Purpose Input Output), etc.; in response to receiving the response message, end sending the notification instruction. In this way, the electronic control unit can use the first communication link and the second communication link to ensure that the notification instruction is successfully sent to the target virtual machine manager of the on-chip integrated system, and ensure that the target virtual machine manager can accurately receive and enter the set low power consumption state according to the notification instruction. The target virtual machine manager sends the notification instruction to the existing virtual machine managers of the on-chip integrated system, and the existing virtual machine managers include virtual machine managers other than the target virtual machine manager, so that all virtual machine managers of the on-chip integrated system can shut down other functional modules managed by themselves except the emergency call functional module and the preset functional module when triggered by the notification instruction.

[0056] It should be noted that the types of the target virtual machine manager and the existing virtual machine manager can be flexibly determined according to the application scenario. For example, the target virtual machine manager may include the virtual machine manager of the instrument cluster, and the existing virtual machine manager may include the virtual machine manager of the in-vehicle infotainment system (IVI) and the virtual machine manager of the intelligent vehicle terminal of the Internet of Vehicles system (Telematics BOX, Tbox). Of course, the existing virtual machine manager may also include other virtual machine managers in addition to the virtual machine manager of the in-vehicle infotainment system and the virtual machine manager of the intelligent vehicle terminal of the Internet of Vehicles system. In this way, after the electronic control unit successfully sends a notification instruction to the target virtual machine manager, the target virtual machine manager shuts down other functional modules managed by itself except the emergency call functional module and the preset functional module, such as shutting down the power of the instrument panel, and shutting down other non-essential peripheral modules and system modules. Afterwards, the target virtual machine manager sends a notification instruction to the existing virtual machine manager of the on-chip integrated system, so that the existing virtual machine manager shuts down other function modules managed by it except the emergency call function module and the preset function module. Specifically, the target virtual machine manager sends a notification instruction to the virtual machine manager of the vehicle infotainment system, so that the virtual machine manager of the vehicle infotainment system shuts down other function modules managed by it except the preset function module and enters the shutdown state. At this time, the virtual machine manager of the vehicle infotainment system can shut down all relevant peripheral power supplies in the domain, such as the central control display screen, camera, hud (Head-Up Display), external DSP, and peripheral power supplies of devices such as wifi and Bluetooth; sends a notification instruction to the virtual machine manager of the intelligent vehicle terminal of the vehicle networking system, so that the virtual machine manager of the intelligent vehicle terminal of the vehicle networking system shuts down other function modules managed by it except the emergency call function module and the preset function module, such as the virtual machine manager of the intelligent vehicle terminal of the vehicle networking system keeps the GNSS module and the voice call function module powered normally, and shuts down other peripheral power supplies except these two; sends a notification instruction to other virtual machine managers, so that other virtual machine managers shut down other function modules managed by them except the preset function module and enter the shutdown state. After that, the virtual machine manager of the intelligent vehicle terminal of the Internet of Vehicles system can report the GPS location and vehicle information to the PSAP (Personal Sound Amplify Product) and then make a voice call for help.

[0057] In actual applications, there are various situations in which a vehicle triggers the on-board emergency call system. If the vehicle's on-chip integrated system is controlled to enter a set low-power state after the vehicle triggers the on-board emergency call system, the vehicle will become unresponsive when the user needs to operate the vehicle. In order to avoid this situation, before the vehicle's on-chip integrated system is controlled to enter the set low-power state, it is also possible to detect whether the vehicle's backup battery is in a working state where the voltage drops and is not charged by the main battery; in response to the backup battery being in a working state, the vehicle's on-chip integrated system is controlled to enter a set low-power state.

[0058] It should be noted that the working state of the vehicle's backup battery in which the voltage drops and is not charged by the main battery is only a recommended condition for controlling the vehicle's on-chip integrated system to enter a set low-power state. Of course, the conditions for controlling the vehicle's on-chip integrated system to enter a set low-power state after the vehicle triggers the on-board emergency call system can be flexibly set according to specific scenarios, such as controlling the vehicle as long as the vehicle triggers the emergency call system, etc. This application does not make specific limitations here. It should also be noted that the vehicle is powered by the main battery and the backup battery. During normal use, the main battery is used. When a collision or other abnormality causes the main battery to be unable to supply power, it will automatically switch to the backup battery for power supply.

[0059] In actual applications, in response to the vehicle triggering the on-board emergency call system, the electronic control unit can also shut down other functional modules managed by the electronic control unit except the emergency call functional module to further reduce power consumption, reserve more power for the emergency call service, and further extend the duration of the emergency call service.

[0060] The present application provides a vehicle power consumption control method, which is applied to the electronic control unit of the vehicle, and in response to the vehicle triggering the on-board emergency call system, controls the vehicle's on-chip integrated system to enter a set low power consumption state; wherein the on-chip integrated system is equipped with a target domain based on a virtual machine hypervisor fusion, and the target domain includes a domain in the electronic and electrical architecture; the set low power consumption state includes the state of shutting down other functional modules except the emergency call function module and the preset function module. The present application can integrate the domain in the electronic and electrical architecture into the on-chip integrated system with the help of the virtual machine hypervisor, improve the integration, and facilitate the control of the domain. After the vehicle triggers the on-board emergency call system, the electronic control unit can control the vehicle's on-chip integrated system to shut down other functional modules except the emergency call function module and the preset function module, thereby reducing the power consumption of other functional modules, reserving more power for the on-board emergency call system, so that the on-board emergency call system can perform emergency call services more persistently and reduce the safety hazards of the vehicle.

[0061] See also Figure 2 , Figure 2Another flow chart of a vehicle power consumption control method provided in an embodiment of the present application.

[0062] A vehicle power consumption control method provided in an embodiment of the present application is applied to a target virtual machine manager of a vehicle on-chip integrated system and may include the following steps:

[0063] Step S201: In response to receiving a notification instruction sent by an electronic control unit of a vehicle, a response message indicating that the notification instruction has been received is sent to the electronic control unit, where the notification instruction includes an instruction indicating that the vehicle triggers an on-board emergency call system.

[0064] Step S202: shut down other function modules managed by the target virtual machine manager except the emergency call function module and the preset function module.

[0065] Step S203: Send a notification instruction to the existing virtual machine manager of the on-chip integrated system to enable the existing virtual machine manager to shut down other functional modules managed by it except the emergency call functional module and the preset functional module, and the existing virtual machine manager includes virtual machine managers other than the target virtual machine manager; wherein the on-chip integrated system is equipped with a target domain based on virtual machine hypervisor fusion, and the target domain includes a domain in the electronic and electrical architecture.

[0066] In a specific application scenario, the target virtual machine manager may include the virtual machine manager of the instrument, and the existing virtual machine managers include the virtual machine manager of the in-vehicle infotainment system, the virtual machine manager of the intelligent in-vehicle terminal of the Internet of Vehicles system, and other virtual machine managers; accordingly, in the process of shutting down other functional modules managed by the target virtual machine manager except the emergency call function module and the preset function module, the other functional modules managed by the virtual machine manager of the instrument except the preset function module may be shut down; in the process of sending a notification instruction to the existing virtual machine manager of the on-chip integrated system so that the existing virtual machine manager shuts down other functional modules managed by the existing virtual machine manager except the emergency call function module and the preset function module, a notification instruction may be sent to the virtual machine manager of the in-vehicle infotainment system so that the virtual machine manager of the in-vehicle infotainment system shuts down other functional modules managed by the existing virtual machine manager except the preset function module and enters the shutdown state, a notification instruction is sent to the virtual machine manager of the intelligent in-vehicle terminal of the Internet of Vehicles system so that the virtual machine manager of the intelligent in-vehicle terminal of the Internet of Vehicles system shuts down other functional modules managed by the existing virtual machine manager except the preset function module, and a notification instruction is sent to other virtual machine managers so that other virtual machine managers shut down other functional modules managed by the existing virtual machine managers except the preset function module and enter the shutdown state.

[0067] The corresponding description of the vehicle power consumption control method of the target virtual machine manager applied to the vehicle on-chip integrated system provided in the embodiment of the present application can be referred to the above embodiment and will not be repeated here.

[0068] See also Figure 3 and Figure 4 , Figure 3 A schematic diagram of the structure of a vehicle power consumption control device provided in an embodiment of the present application is shown in FIG. Figure 4 This is a schematic diagram of the structure of the vehicle power consumption control system in the on-chip integrated system.

[0069] A vehicle power consumption control device provided in an embodiment of the present application may include an electronic control unit and an on-chip integrated system of the vehicle, wherein the on-chip integrated system is equipped with a target domain based on virtual machine hypervisor fusion, and the target domain includes a domain in the electronic and electrical architecture; wherein the on-chip integrated system can run multiple hypervisor systems to perform system services required by users, such as being responsible for GPS positioning, SIM registration to the base station cellular network, and Ecall voice uplink and downlink calls through external audio codec and AMP, and can support the connection of multimedia peripherals; an electronic control unit is used to control the vehicle's on-chip integrated system to enter a set low power consumption state in response to the vehicle triggering the vehicle-mounted emergency call system, and the set low power consumption state includes shutting down the state of other functional modules except the emergency call function module and the preset function module, and in addition, the electronic control unit can be responsible for collecting vehicle body information and controlling the vehicle body domain. And the active triggering or passive collision triggering of Ecall needs to be processed by the ECU first, and then notify the SOC to perform further Ecall business processing.

[0070] A vehicle power consumption control system provided in an embodiment of the present application may include a host virtual machine manager based on a virtual machine manager integrated in a vehicle on-chip integrated system, a virtual machine manager of an in-vehicle infotainment system, a virtual machine manager of an intelligent in-vehicle terminal of an Internet of Vehicles system, and other virtual machine managers, wherein the virtual machine manager of the on-chip integrated system closes other functional modules except the emergency call functional module and the preset functional module after receiving a notification instruction, and the notification instruction includes an instruction indicating that the vehicle triggers the in-vehicle emergency call system. The host virtual machine manager may be a Linux or RTO system, which is used to manage instruments and other vehicle body services; the virtual machine manager of the in-vehicle infotainment system may be an Android system, which is responsible for multimedia entertainment system services; the virtual machine manager of an intelligent in-vehicle terminal of an Internet of Vehicles system may be a Linux system, which is responsible for network domain functions, such as making calls, text messages, Ecall, gnss, surfing the Internet, and other functions; other virtual machine managers may be Linux or RTO systems, which may customize related business functions, such as the intelligent driving domain, and the like.

[0071] In order to facilitate understanding of the vehicle power consumption control method provided by this application, Figure 4 The system shown describes the present application scheme, such as Figure 5As shown, the following processes may be included:

[0072] The MCU in the vehicle body MCU determines that the SOS button actively triggers the Ecall or the vehicle collision triggers the Ecall, and detects that the backup battery enters a working state where the voltage drops and the main battery no longer charges the backup battery, then turns off the power of other peripherals except the Ecall function;

[0073] The MCU of the body ECU notifies the Cluster vm of the SOC through SPI / or UART that the current system is in the Ecall state and has entered the backup battery working state. At the same time, it determines whether the Cluster vm returns a status synchronization message after receiving the Ecall message. If not, it continues to notify through ecall_gpio;

[0074] After receiving the Ecall trigger message from the MCU, the Cluster VM CarManager replies to the MCU that the Ecall message is received normally, then turns off the power of the instrument panel, and shuts down other non-essential peripheral modules and system modules. It notifies the IVI VM, Tbox VM and other VMs through the inter-VM IPC communication mechanism that they are currently in the Ecall emergency call state and are working on the backup battery.

[0075] After receiving the Ecall emergency call message from the Cluster, the IVI VM CarManager_IVI turns off the power of all related peripherals in the domain and enters the shutdown state;

[0076] After Tbox VM CarManager_Tbox receives the Ecall emergency call information sent by Cluster, it keeps the power supply of GNSS module and voice call function module normal and turns off the power supply of other peripheral modules;

[0077] Other VMs turn off their related peripheral power supplies and enter shutdown state;

[0078] The Ecall service module in the Tbox VM reports the GPS location and vehicle-side information to the PSAP, and then makes a voice call for help.
