[0050] In some embodiments, as Figure 1 As shown, an embodiment of the present application provides a vehicle control method, including:

[0051] Step S101, when the communication device receives a control instruction, determining the instruction execution device corresponding to the control instruction;

[0052] Step S102, determining the main control device corresponding to the control instruction based on the instruction execution device;

[0053] Step S103, controlling the main control device to start working, and controlling the communication device to send control instructions to the main control device;

[0054] Step S104 : When the main control device receives the control instruction, the main control device is controlled to respond to the control instruction so that the main control device controls the instruction execution device.

[0055] In this embodiment, a vehicle control method is proposed, wherein the vehicle includes a communication device, a gateway device and multiple control units, the communication device is connected to the gateway device, and the gateway device is connected to each control unit, wherein the communication device is a device for vehicle communication, the gateway device is a device for completing conversion between different network protocols, and the control unit is a sub-module in the vehicle that implements specific functions.

[0056] For example, the vehicle may be a self-driving car.

[0057] Exemplarily, the vehicle may be a new energy electric vehicle.

[0058] For example, the communication device may be a vehicle-connected terminal TBOX (Telematics Box, remote communication terminal).

[0059] Exemplarily, the gateway device may include a central gateway and a domain controller of the vehicle.

[0060] For example, the control unit may be a vehicle-side ECU (electronic control unit).

[0061] For example, the communication device can communicate with the cloud server and receive remote control commands or text messages from the remote server.

[0062] When the communication device receives a control instruction, it determines an instruction execution device corresponding to the control instruction, wherein the control instruction is an instruction for controlling the vehicle, and the instruction execution device is a device involved in the control instruction.

[0063] Exemplarily, the communication device may receive control instructions sent by a cloud server.

[0064] For example, the communication device may receive a control command input by a vehicle passenger.

[0065] For example, the control instruction may be specifically to open a car window, and the corresponding instruction execution device is the car window.

[0066] For example, the control instruction may specifically be remote photo taking, and the corresponding instruction execution device is a vehicle-mounted camera.

[0067] For example, the control instruction may specifically be uploading a vehicle driving log, and the corresponding instruction execution device is a vehicle database.

[0068] Based on the instruction execution device, a master control device corresponding to the control instruction is determined among the communication device, the gateway device and the plurality of control units. The master control device is a device that implements the control instruction.

[0069] Exemplarily, the main control device may be a communication device, a gateway device, or a control unit.

[0070] Exemplarily, the main control device may be a combination of a communication device and a gateway device.

[0071] Exemplarily, the main control device may be a combination of multiple control units.

[0072] Exemplarily, the main control device may be a combination of a communication device and a plurality of control units.

[0073] In a normal state, the communication device, the gateway device and the plurality of control units are in a closed state. After the master control device is determined, the master control device is started and controlled to start working.

[0074] After the main control device is started, the control communication device sends a control instruction to the main control device.

[0075] Exemplarily, when the master control device is a gateway device, the control communication device sends a control instruction to the gateway device.

[0076] Exemplarily, when the main control device is a communication device, the control instructions are directly stored by the communication device.

[0077] Exemplarily, when the main control device is a control unit, the control communication device sends the control instruction to the control unit through the gateway device.

[0078] When the main control device receives the control instruction, the main control device is controlled to respond to the control instruction so that the main control device controls the instruction execution device.

[0079] For example, the main control device may be controlled to respond to an "open the window" instruction, and the main control device may then control the window to open.

[0080] For example, the main control device may be controlled to respond to a "remote photo taking" instruction, and the main control device may then control the vehicle-mounted camera to take photos.

[0081] For example, the main control device may be controlled to respond to an "upload driving log" instruction, and the main control device may then read the driving log in the vehicle database.

[0082] It should be noted that this embodiment starts the main control device after determining the main control device corresponding to the control instruction among the communication device, gateway device and multiple control units based on the specific control instruction. Since only the main control device is started, other devices in the vehicle remain in a closed state, avoiding frequent startup of devices such as the communication device, gateway device and multiple control units, thereby reducing the energy consumption of the vehicle.

[0083] It should also be noted that this embodiment can implement vehicle wake-up strategies and mechanisms for different stages, different trigger sources, and different vehicle-side controller domains. By starting some devices in the vehicle, the judgment and logical operations of local wake-up of the entire vehicle can be realized. This embodiment can wake up or not wake up each device in the vehicle on demand according to the remote control type of the business, ensuring that the corresponding functions are realized while greatly reducing the power consumption of the vehicle battery, thereby further reducing the risk of battery power feeding caused by frequent operations.

[0084] The vehicle control method in this embodiment determines the main control device among the communication device, gateway device and multiple control units by parsing the control instructions, and optimizes the startup frequency of each device in the vehicle and reduces the energy consumption of the vehicle by starting only the main control device and keeping other devices in the off state.

[0085] In some embodiments, an embodiment of the present application provides a vehicle control method, which determines a main control device corresponding to a control instruction based on an instruction execution device, including:

[0086] Step S201, obtaining connection relationships between multiple executable devices and communication devices, gateway devices, and multiple control units;

[0087] Step S202 : Determine, based on the connection relationship, which instruction execution device corresponds to the master control device among the communication device, the gateway device, and the plurality of control units.

[0088] In this embodiment, the vehicle includes multiple executable devices, wherein the instruction execution device is any executable device among the multiple executable devices, and the communication device, the gateway device and each control unit are connected to at least one executable device.

[0089] For example, the multiple executable devices may be specific devices such as vehicle windows, vehicle doors, vehicle audio, and vehicle databases.

[0090] Acquire corresponding connection relationships between the plurality of executable devices and the communication apparatus, the gateway apparatus, and the plurality of control units, wherein the connection relationships represent control relationships between the plurality of executable devices and the communication apparatus, the gateway apparatus, and the plurality of control units.

[0091] Exemplarily, the plurality of executable devices may include device 1, device 2, device 3, device 4, device 5, and device 6.

[0092] The connection relationship may be that the communication device controls device 1 and device 2, the gateway device controls device 3 and device 4, the control unit A controls device 5, and the control unit B controls device 6.

[0093] According to the connection relationship, among the communication device, the gateway device and the plurality of control units, it is determined that the instruction execution device corresponds to the main control device.

[0094] Exemplarily, when the instruction execution device is device 2, the communication device is set as the master control device.

[0095] Exemplarily, when the instruction execution device is device 4, the gateway device is set as the master device.

[0096] Exemplarily, when the instruction execution device is device 6, the control unit B is set as the master control device.

[0097] In some embodiments, an embodiment of the present application provides a vehicle control method, which controls a main control device to start working, including:

[0098] Step S301: When the master control device is a gateway device, controlling the communication device to send a first wake-up instruction to the gateway device;

[0099] Step S302 : When the gateway device receives the first wake-up instruction, the gateway device is controlled to respond to the first wake-up instruction so that the gateway device starts working.

[0100] In this embodiment, when the master control device is a gateway device, the control communication device sends a first wake-up instruction to the gateway device, wherein the first wake-up instruction is an instruction for waking up the gateway device.

[0101] Exemplarily, the first wake-up instruction may be a message for waking up the gateway device.

[0102] When the gateway device receives the first wake-up instruction, the gateway device is controlled to respond to the first wake-up instruction so that the gateway device starts to work.

[0103] For example, the communication device may be a TBOX, and the gateway device may be a central gateway & domain controller, such as Figure 2 As shown, the central gateway and domain controller serve as the master nodes for scenario implementation, and TBOX only wakes up the central gateway and domain controller. (TBOX wakes up the central gateway and domain controller, but not the entire vehicle. The central gateway and domain controller lead the vehicle's wake-up state until the task is completed.)

[0104] After receiving the cloud wake-up SMS and checking the content of the SMS, the TBOX logs into the cloud server and sends an active CAN NM message to wake up the central gateway and domain controller. The connection between the TBOX and the central gateway and domain controller SOMEIP SD is established.

[0105] The TBOX receives a specific remote control command (TBOX recognizes the specific remote control command and, based on the SMS content, determines that the entire vehicle does not need to be woken up). Based on the different remote control functions, the TBOX sends the corresponding SOMEIP remote control service application message to the central gateway and domain controller. The central gateway and domain controller then complete the vehicle wake-up and functional logic processing (the TBOX does not need to send "Service A / Method B" and "Service A / Method C"). The TBOX actively sends CAN NM messages for 40 seconds (for example) and then stops sending them. Whether to remain awake or enter dormancy is determined by the NM message from the central gateway and domain controller (the TBOX remains awake if it receives an NM message and enters dormancy if it does not).

[0106] For example, the data interaction process is shown in Table 1.

[0107] Table 1

[0108]

[0109]

[0110] In some embodiments, an embodiment of the present application provides a vehicle control method, which controls a main control device to start working, including:

[0111] Step S401: When the master control device is a first control unit, the communication device is controlled to send a vehicle wake-up instruction to the gateway device, and the first control unit is any control unit among the multiple control units;

[0112] Step S402 : When the gateway device receives the vehicle wake-up instruction, the gateway device is controlled to respond to the vehicle wake-up instruction to put the vehicle into a wake-up state.

[0113] Step S403, when the vehicle is in the awake state, controlling the communication device to send a second awakening instruction to the first control unit;

[0114] Step S404 : When the first control unit receives the second wake-up instruction, the first control unit is controlled to respond to the second wake-up instruction so that the first control unit starts to work.

[0115] In this embodiment, when the main control device is the first control unit, the control communication device sends a vehicle wake-up instruction to the gateway device, wherein the first control unit is any control unit among multiple control units, and the vehicle wake-up instruction is an instruction to wake up the entire vehicle.

[0116] Exemplarily, the first control unit may be a vehicle-side ECU corresponding to the vehicle window.

[0117] When the gateway device receives the vehicle wake-up instruction, the gateway device is controlled to respond to the vehicle wake-up instruction to put the vehicle into a wake-up state.

[0118] For example, the control gateway device responds to the vehicle wake-up instruction and starts the vehicle to put the vehicle in the wake-up state.

[0119] When the vehicle is in the awake state, the control communication device sends a second awakening instruction to the first control unit, wherein the second awakening instruction is an instruction to start the first control unit.

[0120] When the first control unit receives the second wake-up instruction, the first control unit is controlled to respond to the second wake-up instruction, so that the first control unit starts to work.

[0121] Exemplarily, the communication device may be a TBOX, the gateway device may be a central gateway & domain controller, and the first control unit may be a vehicle-side ECU.

[0122] like Figure 3 As shown in the figure, after receiving the cloud wake-up SMS, TBOX logs in to the cloud server and sends an active CAN NM message to wake up the central gateway and domain controller. The connection between TBOX and the central gateway and domain controller SOMEIP SD is established.

[0123] After the TBOX receives a specific remote control command (TBOX recognizes the specific remote control command and, based on the SMS content, determines whether the vehicle needs to be woken up), it sends a SOMEIP wake-up application message, Service A / Method B, to wake the vehicle. After obtaining the vehicle network wake-up command via Service A / Method D, the TBOX sends a SOMEIP remote control service application message to the vehicle-side ECU. 40 seconds later (the timer starts when the TBOX receives the specific remote control command), the TBOX sends a SOMEIP cancel wake-up application message, Service A / Method C, to form a command closed loop with Service A / Method B. TBOX stops sending active NM messages after 40 seconds. Whether the TBOX remains awake or goes into sleep is determined by the NM message from the vehicle-side ECU (the TBOX remains awake if it receives an NM message and goes into sleep if it does not).

[0124] For example, the data interaction process is shown in Table 2.

[0125] Table 2

[0126]

[0127]

[0128] In some embodiments, an embodiment of the present application provides a vehicle control method, which controls a main control device to start working, including:

[0129] Step S501: When the main control device includes a communication device and a second control unit, the communication device is controlled to start working and to send a vehicle wake-up instruction to the gateway device. The second control unit is any one of the multiple control units.

[0130] Step S502, when the gateway device receives the vehicle wake-up instruction, controlling the gateway device to respond to the vehicle wake-up instruction to put the vehicle into a wake-up state;

[0131] Step S503, when the vehicle is in the awake state, controlling the communication device to send a third awakening instruction to the second control unit;

[0132] Step S504 : When the second control unit receives the third wake-up instruction, the second control unit is controlled to respond to the third wake-up instruction, so that the second control unit starts to work.

[0133] In this embodiment, when the main control device includes a communication device and a second control unit, the communication device is controlled to start working and to send a vehicle wake-up instruction to the gateway device, wherein the second control unit is any one of the multiple control units.

[0134] Illustratively, in a case where the master control device includes a communication device and a second control unit, the second control unit may be a slave control device of the communication device, and the communication device and the second control unit communicate with each other to form the master control device.

[0135] When the gateway device receives the vehicle wake-up instruction, the gateway device is controlled to respond to the vehicle wake-up instruction to put the vehicle into a wake-up state.

[0136] When the vehicle is in the awake state, the control communication device sends a third awakening instruction to the second control unit, wherein the third awakening instruction is an instruction to start the second control unit.

[0137] When the second control unit receives the third wake-up instruction, the second control unit is controlled to respond to the third wake-up instruction, so that the second control unit starts to work.

[0138] Exemplarily, in the case where the main control device includes a communication device and a second control unit, the communication device and the second control unit need to be started simultaneously.

[0139] Exemplarily, the communication device may be a TBOX, the gateway device may be a central gateway & domain controller, and the second control unit may be a vehicle-side ECU.

[0140] like Figure 4 As shown in the figure, after receiving the cloud wake-up SMS, TBOX logs in to the cloud server and sends active CAN NM messages to wake up the central gateway and domain controller. CAN NM messages need to be sent continuously until the task is completed and the connection between TBOX and the central gateway and domain controller SOMEIP SD is established.

[0141] TBOX obtains a specific remote control command (TBOX recognizes the specific remote control command and determines the need to wake up the entire vehicle based on the SMS content). TBOX then sends a SOMEIP wake-up application message Service A / Method B to wake up the entire vehicle. After obtaining the vehicle network wake-up command through Service A / Method D, TBOX sends a SOMEIP remote control service application message to the vehicle-side ECU. After the remote control task is completed, TBOX sends a SOMEIP cancel wake-up application message Service A / Method C to form a command closed loop with Service A / Method B. After that, TBOX no longer actively sends CAN NM messages. Whether to remain awake or enter sleep mode is determined by the CAN NM message from the vehicle-side ECU (TBOX remains awake if it receives an NM message and enters sleep mode if it does not).

[0142] For example, the data interaction process is shown in Table 3.

[0143] Table 3

[0144]

[0145]

[0146] In some embodiments, an embodiment of the present application provides a vehicle control method, which controls a main control device to start working, including:

[0147] Step S601: When the master control device is a communication device, control the communication device to start working.

[0148] In this embodiment, when the master control device is a communication device, the communication device is controlled to start working.

[0149] For example, the communication device is a TBOX, such as Figure 5 As shown in the figure, after receiving the cloud wake-up SMS, TBOX logs in to the cloud server. After identifying the SMS content, it does not send active CAN NM messages to wake up the central gateway & domain controller or the vehicle. TBOX and the central gateway & domain controller do not need to complete the SOMEIP SD connection.

[0150] TBOX only stays awake and completes the remote control task, then feeds the remote control results back to the cloud server. After the task is completed, TBOX automatically goes into sleep mode.

[0151] For example, the data interaction process is shown in Table 4.

[0152] Table 4

[0153]

[0154] In some embodiments, an embodiment of the present application provides a vehicle control method. After the main control device responds to the control instruction, the method further includes:

[0155] Step S701, obtaining a response result corresponding to the control instruction;

[0156] Step S702: After the gateway device outputs the response result, the main control device is controlled to stop working.

[0157] In this embodiment, a response result corresponding to the control instruction is obtained, wherein the response result is a result after the control instruction is executed.

[0158] After the gateway device outputs the response result, the main control device is controlled to stop working.

[0159] For example, the CAN NM message is only used by the TBOX to wake up the central gateway and domain controller via CAN.

[0160] Service A / Method B (Service ID / Method ID) is used by TBOX to initiate a vehicle wake-up request to the central gateway & domain controller.

[0161] Service A / Method C (Service ID / Method ID) is used by TBOX to cancel the vehicle wake-up request to the central gateway & domain controller.

[0162] Service A / Method D (Service ID / Method ID) is used by TBOX to obtain the vehicle wake-up status from the central gateway and domain controller.

[0163] The functional scenario attributes of a vehicle are mainly divided into four categories, namely CASE1, 2, 3, and 4. The detailed description is shown in Table 5 below.

[0167]

[0168] In some embodiments, as Figure 6 As shown, an embodiment of the present application provides a vehicle control device 800, which includes a communication device, a gateway device, and multiple control units. The communication device is connected to the gateway device, and the gateway device is connected to each control unit. The vehicle control device 800 includes:

[0169] The processing unit 802 is configured to determine an instruction execution device corresponding to a control instruction when the communication device receives the control instruction;

[0170] The processing unit 802 is further configured to determine a master control device corresponding to the control instruction based on the instruction execution device, where the master control device is any one of a communication device, a gateway device, and a plurality of control units;

[0171] The control unit 804 is used to control the main control device to start working and control the communication device to send control instructions to the main control device;
