[0059] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0061] In order to solve the problems of the prior art, the embodiments of the present application provide a vehicle control method, device, equipment, storage medium and program product. When starting the sentinel mode, firstly, by obtaining the set start time set by the user and the cold start duration of the intelligent driving domain controller, the advance start time is determined according to the set start time and the cold start duration. The advance start time is the start time of the driving domain controller in advance. When the advance start time is reached, the power supply controller can be started in advance so that the power supply controller provides power to the intelligent driving domain controller, and the intelligent driving domain controller is started. Then, according to the first startup state in the startup process of the intelligent driving domain controller, and when the set start time is reached, the startup of the intelligent driving domain controller is completed, and an activation signal is sent to the intelligent driving domain controller so that the intelligent driving domain controller activates the sentinel mode, which can ensure that the sentinel mode is started on time and reduce the risk of damage to the vehicle during the cold start process of the intelligent driving domain controller.

[0062] The following first introduces the vehicle control system provided in the embodiment of the present application.

[0063] Reference Figure 1 , Figure 1 A schematic structural diagram of a vehicle control system provided in an embodiment of the present application is shown, where the vehicle control system 10 includes: a vehicle control device 11 and a server 12 connected to the vehicle control device 11 .

[0064] In this embodiment, the server 12 may be a local server that performs computing tasks in the vehicle, or may be a cloud server that is remotely located.

[0065] The vehicle control device 11 may include an on-board communication terminal (Telematics Box, T-BOX) 401, an intelligent driving domain controller 403 and a power supply controller 402; wherein the on-board communication terminal 401 is connected to the intelligent driving domain controller 403 via a CAN_FD bus or a CAN bus, and the intelligent driving domain controller 403 is connected to the power supply controller 402.

[0066] In some embodiments, the intelligent driving domain controller 403 may include a first processor and a second processor, wherein the first processor may be used to process the power supply control task of the power supply controller, and the second processor may be used to process the computing task of executing the activation sentry mode.

[0067] As an example, the first processor may be an M-core processor, and the second processor may be an A-core processor.

[0068] In some embodiments, the vehicle control system may further include a mobile terminal 13 , which is connected to the server 11 .

[0069] In this embodiment, the user can set the sentinel mode through the mobile terminal 13, and then upload the set sentinel mode to the cloud server or the local processor through the mobile terminal 13, and then the on-board communication terminal 401 can obtain the setting information of the sentinel mode through the cloud server or the local processor, and then control the intelligent driving domain controller 402 to start through the CAN_FD bus according to the setting information, thereby completing the activation of the sentinel mode.

[0070] Specifically, in the vehicle control system, when the sentinel mode is started, the setting information of the sentinel mode in the processor and the cold start duration of the intelligent driving domain controller can be obtained through the on-board communication terminal. The setting information can be the set start time set by the user, and the cold start duration can be the start duration of the intelligent driving domain controller. Then the on-board communication terminal starts the power supply controller in advance according to the set start time, so that the power supply controller supplies power to the intelligent driving domain controller. After the intelligent driving domain controller is powered on, the intelligent driving domain controller starts, and then the on-board communication terminal controls the intelligent driving domain controller to activate the sentinel mode, which can ensure that the sentinel mode is started on time and reduce the risk of damage to the vehicle during the cold start of the intelligent driving domain controller.

[0071] The following is an introduction to the vehicle control method provided in the embodiments of the present application.

[0072] Figure 2 FIG. 1 is a flow chart of a vehicle control method provided by an embodiment of the present application. Figure 2 As shown, the vehicle control method may include S201-S205:

[0073] S201, the vehicle communication terminal obtains the setting start time of the sentinel mode and the cold start duration of the intelligent driving domain controller.

[0074] In some embodiments, in order to start the sentinel mode on time, the set start time of the sentinel mode set by the user needs to be at least in advance by the cold start duration of the smart timely rain controller to ensure that the sentinel mode is started on time at the set start time.

[0075] Specifically, obtaining the cold start duration of the intelligent driving domain controller may include:

[0076] Obtain a first preset startup duration of the first processor and a second preset startup duration of the second processor;

[0077] A cold start duration is determined based on the first preset start duration and the second preset start duration.

[0078] In this embodiment, when determining the cold start duration, it is necessary to obtain the first preset startup duration of the first processor and the second preset startup duration of the second processor respectively, and then sum the first preset startup duration and the second preset startup duration, and determine the sum as the cold start duration.

[0079] In some embodiments, as an example, the first preset startup time of the first processor and the second preset startup time of the second processor can be obtained after multiple tests, and the staff stores the first preset startup time and the second preset startup time in the vehicle communication terminal.

[0080] As an example, it can be measured through experiments that the first preset startup time may be 300ms, and the second preset startup time may be 3 minutes; in addition, for different intelligent driving domain controllers, the first preset startup time may be inconsistent, and the second preset startup time may also be inconsistent, so each intelligent driving domain controller can be tested in advance to store the first preset startup time and the second preset startup time in the server, so that the vehicle-mounted communication terminal can directly retrieve them.

[0081] In some embodiments, before S201, the method may further include:

[0082] In response to a user's sentry mode setting information operation, generating a startup task based on the sentry mode setting information;

[0083] The startup task is stored in a server, wherein the server pre-stores the cold start duration of the driving domain controller;

[0084] S201 may specifically include:

[0085] The vehicle communication terminal obtains the startup task and the cold start time of the intelligent driving domain controller from the server;

[0086] Parse the data of the startup task to obtain the setting startup time of the sentinel mode.

[0087] In this embodiment, before obtaining the set start time, the user can set the sentry mode through the vehicle's local processor, that is, set the sentry mode through the touch screen of the vehicle's central control. The user can also set the setting information of the sentry mode through the application software of the mobile terminal, so that the server can generate a startup task according to the setting information of the sentry mode, wherein the startup task may include the set start time of the sentry mode.

[0088] In this embodiment, the vehicle communication terminal can obtain the startup task and the pre-stored cold start duration from the server, and then perform data analysis on the startup task to obtain the set startup time, so as to determine the advance startup time and ensure that the sentinel mode is started on time.

[0089] S202: Based on the difference between the set start time and the cold start duration, obtain the advance start time for the intelligent driving domain controller to be pre-started.

[0090] In this embodiment, the advance start time can be determined by setting the difference between the start time and the cold start duration, that is, the intelligent driving domain controller can be started at the advance start time to save the cold start duration and ensure that the sentinel mode is started on time at the set start time.

[0091] As an example, if the user sets the start time to 18:00 and the cold start duration is 3 minutes, the advance start time can be 17:57, that is, the intelligent driving domain controller is started at 17:57. Of course, the intelligent driving domain controller can also be started at a preset time before 17:57 to reduce delays caused by errors in the environment or electronic components and ensure that the sentinel mode is started on time.

[0092] S203, when the advance start time is reached, the vehicle communication terminal wakes up the power supply controller so that the power supply controller provides power to the intelligent driving domain controller, and the intelligent driving domain controller starts.

[0093] In this embodiment, when the clock of the vehicle control system detects the early start time, the on-board communication terminal wakes up the power supply controller, and the power supply controller starts working to provide power to the intelligent driving domain controller to ensure the normal operation of the intelligent driving domain controller.

[0094] Reference Figure 3 Specifically, the startup of the intelligent driving domain controller may include:

[0095] S301, the first processor starts up in response to a power signal from a power supply controller;

[0096] S302, the in-vehicle communication terminal obtains a second startup state of the first processor;

[0097] S303, when the second startup state is determined to be startup completion, the vehicle communication terminal sends a startup signal to the second processor;

[0098] S304: The second processor is started according to the start signal.

[0099] In this embodiment, when starting the intelligent driving domain controller, the first processor and the second processor need to be started step by step, that is, the first processor responds to the power signal of the power supply controller, and the first processor is started first, wherein the power signal is used to indicate that the power supply controller provides power to the intelligent driving domain controller. It is worth noting that the power supply controller provides power to the first processor, indicating that the first processor can receive the power signal of the power supply controller, and the first processor is powered on and starts to start.

[0100] During the startup of the first processor, the on-board communication terminal obtains the second startup status of the first processor in real time. When the second startup status of the first processor is determined to be startup completion, it indicates that the startup of the first processor is now completed and a startup signal needs to be sent to the second processor so that the second processor can be started according to the startup signal.

[0101] As an example, the second startup state may include the first processor startup in progress and the first processor startup completed.

[0102] In some embodiments, the second startup state may further include a startup timeout. After S303, the method further includes:

[0103] Obtain a second startup time at which the first processor is started and a third startup time corresponding to the second startup state, where the third startup time indicates a time at which the second startup state changes;

[0104] Determining a third startup duration based on the second startup time and the third startup time;

[0105] When the third startup time length is greater than the first preset startup time length, determining the second startup state as startup timeout;

[0106] When the second startup state is determined to be startup timeout, the method further includes:

[0107] The vehicle-mounted communication terminal sends a first sleep signal to the first processor to put the first processor into sleep mode and stop the first processor from starting up.

[0108] In this embodiment, for some special situations, the startup timeout of the intelligent driving domain controller may be caused, so it is necessary to obtain the second startup time of the first processor and the third startup time corresponding to the second startup state, wherein the third startup time indicates the moment when the second startup state changes, that is, the third startup duration is the duration for the first processor to change from startup to startup completion. When the third startup duration is greater than the first preset startup duration, it indicates that the startup of the first processor has timed out, and the second startup state of the first processor needs to be modified to startup timeout. When the second startup state is determined to be startup timeout, the on-board communication terminal needs to send a sleep signal to the first processor to put the first processor into sleep mode, stop starting the sentinel mode, and send a reminder message to the user.

[0109] As an example, the second startup time may be 17:57:00:000; the third startup time may be 17:57:00:400; the first preset startup duration is 300ms, then the third startup duration is greater than the first preset startup duration, and the second startup state may be determined as a startup timeout.

[0110] In some other embodiments, S301 may include:

[0111] Get the battery power corresponding to the power supply controller;

[0112] When the battery power is greater than the preset power, the first processor is started.

[0113] In this embodiment, in order to ensure that there is sufficient power to start the intelligent driving domain controller and maintain the sentinel mode, it is necessary to obtain the battery power when the first processor is started. When the battery power is greater than the preset power, the first processor is started, which can ensure that the first processor has sufficient power to start.

[0114] In some other embodiments, after the first processor is started, the vehicle communication terminal sends a start signal to the second processor. At this time, the second processor receives the start signal, starts to start, and enters the starting state until the second processor is started.

[0115] In some other embodiments, after S304, the method may further include:

[0116] The vehicle communication terminal obtains a fourth startup time of the second processor, a third startup state of the second processor and a corresponding fifth startup time, wherein the fifth startup time is a time when the third startup state changes from ready to start to completed startup;

[0117] Determining a fourth startup duration based on the fourth startup time and the fifth startup time;

[0118] When the fourth startup time length is greater than the second preset startup time length, the third startup state is determined to be startup timeout;

[0119] When the third startup state is determined to be a startup timeout, the in-vehicle communication terminal generates a second sleep signal;

[0120] The vehicle-mounted communication terminal sends a second sleep signal to the first processor and the second processor, so that the first processor and the second processor enter a sleep state according to the second sleep signal.

[0121] In this embodiment, similarly, the second processor may also experience a startup timeout, so it is necessary to count the fourth startup duration of the second processor, that is, count the second processor from the fourth startup time when the startup begins to the fifth startup time when the startup is completed, and obtain the fourth startup duration. When the fourth startup duration is less than or equal to the second preset startup duration, the third startup state of the second processor is determined to be startup completion. When the fourth startup duration is greater than the second preset startup time, the third startup state of the second processor is determined to be startup timeout. At this time, the on-board communication terminal generates a second sleep signal and sends the second sleep signal to the first processor and the second processor. The first processor and the second processor will stop working according to the second sleep signal and re-enter the sleep state.

[0122] S204, the vehicle-mounted communication terminal obtains the first startup state of the intelligent driving domain controller.

[0123] In this embodiment, since the first processor set and the second processor are started in a distributed manner, it is necessary to obtain the second startup state of the first processor and the third startup state of the second processor respectively. When the second startup state and the third startup state are both determined to be startup completed, the first startup state is determined to be startup completed, and the second startup state and / or the third startup state are determined to be non-startup completed, then the first startup state is determined to be startup timeout.

[0124] As an example, non-boot completion may include boot timeout and booting.

[0125] S205, when the first startup state is determined to be startup completion and the set startup time is reached, the vehicle communication terminal sends an activation signal to the intelligent driving domain controller, so that the intelligent driving domain controller activates the sentinel mode according to the activation signal.

[0126] In this embodiment, the first startup state is determined to be startup completion, indicating that the startup of the intelligent driving domain controller is completed at this time. At this time, the set startup time is reached, the on-board communication terminal can send an activation signal to the intelligent driving domain controller, and the intelligent driving domain controller can activate the sentry mode according to the activation signal.

[0127] In an embodiment of the present application, when starting the sentinel mode, the set start time set by the user and the cold start duration of the intelligent driving domain controller are first obtained, and the advance start time is determined according to the set start time and the cold start duration. The advance start time is the start time of the advance control driving domain controller. When the advance start time is reached, the power supply controller can be started in advance so that the power supply controller provides power to the intelligent driving domain controller, and the intelligent driving domain controller is started. Then, according to the first startup state in the startup process of the intelligent driving domain controller, and when the set start time is reached, the startup of the intelligent driving domain controller is completed, and an activation signal is sent to the intelligent driving domain controller so that the intelligent driving domain controller activates the sentinel mode, which can ensure that the sentinel mode is started on time and reduce the risk of damage to the vehicle during the cold start process of the intelligent driving domain controller.
