Description

Technical Field

[0001] The present application belongs to the technical field of vehicle control, and in particular, relates to a vehicle remote control method, device, equipment, storage medium and program product. Background Art

[0002] At present, the execution of control instructions in vehicles adopts an uninterruptible execution mode, that is, the next control instruction can only be executed after the currently executing control instruction is completed; for example, when the owner issues an automatic parking instruction, if the owner issues a shutdown instruction at this time, the automatic parking instruction cannot be terminated immediately. Instead, the shutdown instruction can be executed after the automatic parking instruction is executed.

[0003] In the above-mentioned related technologies, when the current control command is being executed, the control command is not interruptible, resulting in some control commands being unable to respond in time and unable to flexibly execute the control commands issued by the user. At the same time, when emergency commands need to be executed, if other control commands are currently being executed, the emergency commands cannot be executed in time, which may cause damage to the vehicle.

[0058] 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.

[0059] 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 existence of other identical elements in the process, method, article or device including the elements.

[0060] In order to solve the problems of the prior art, the embodiments of the present application provide a vehicle remote control method, device, equipment, storage medium and program product. In the embodiments of the present application, when there are a first control instruction and a second control instruction in the vehicle terminal at the same time, it is necessary to judge the priority of the first control instruction and the second control instruction to determine the control instruction to be executed. In the vehicle terminal, the priority of the control instruction can be distinguished by the message. Specifically, the first control instruction and the second control instruction can be parsed respectively to obtain the first message and the second message, and then the priority of the first control instruction and the second control instruction can be determined by the first message and the second message. When the second priority of the second control instruction is higher than the first priority of the first control instruction, it indicates that the urgency of the second control instruction is higher than the first control instruction at this time, the terminal executes the first control instruction, and then executes the second control instruction to obtain the execution result; that is, by judging the control instructions of different priorities, the execution order is determined to flexibly execute the control instructions and improve the user experience.

[0061] The following first introduces the vehicle remote control method provided in the embodiment of the present application.

[0062] Figure 1 FIG. 1 is a flow chart of a vehicle remote control method provided by an embodiment of the present application. Figure 1 As shown, the vehicle remote control method may include S101-S105:

[0063] S101, obtaining a first control instruction and a second control instruction.

[0064] In an embodiment of the present application, in a vehicle-mounted terminal, when a corresponding control instruction is executed through the vehicle-mounted terminal, when the vehicle is not started, the processor can only execute one control instruction. Therefore, if the Internet of Things module in the vehicle-mounted terminal has already stored a first control instruction, if a second control instruction is received, then it is necessary to determine the control instruction that needs to be executed, that is, the first control instruction and the second control instruction can be obtained in the vehicle-mounted terminal.

[0065] As an example, the first control instruction is a control instruction being executed or received before the second control instruction is received, that is, the first control instruction is a control instruction to be executed or being executed by the vehicle terminal before the second control instruction is received.

[0066] It is worth noting that the first control instruction and the second control instruction are commands that the vehicle terminal can control autonomously, such as: automatic parking, remote vehicle search, automatic start and stop, automatic shutdown and unlocking of doors.

[0067] In some other embodiments, obtaining the second control instruction may include:

[0068] A second control instruction is obtained from the cloud server, where the second control instruction is an instruction triggered in response to an operation of a user on the control terminal.

[0069] In this embodiment, the user can issue a second control instruction through the application on the control terminal, the control terminal transmits the second control instruction to the cloud server, and then the cloud server transmits the second control instruction to the vehicle terminal through the network, so that the user can issue the control instruction remotely.

[0070] In some other embodiments, the first control instruction may also be sent by the user through a control terminal, and the transmission method is consistent with that of the second control instruction, which will not be elaborated here.

[0071] S102, respectively parse the first control instruction and the second control instruction to obtain a first message corresponding to the first control instruction and a second message corresponding to the second control instruction.

[0072] In some embodiments, after the vehicle terminal receives the first control instruction and the second control instruction, it is necessary to perform message parsing on the first control instruction and the second control instruction to obtain the first message and the second message to prepare for the subsequent execution of the control instruction.

[0073] S103: Determine priorities of the first control instruction and the second control instruction based on the first message and the second message.

[0074] In some embodiments, the first message includes a first message identification number, and the second message includes a second message identification number. The first message identification number can be used as an identity identifier of the first control instruction, and the second message identification number can be used as an identity identifier of the second control instruction, so that the vehicle-mounted terminal can identify the first control instruction or the second control instruction.

[0075] In some specific embodiments, the vehicle-mounted terminal may include an Internet of Things module, a serial interface module and a processor, and the Internet of Things module and the serial interface module are both connected to the processor, wherein the Internet of Things module can receive control instructions sent by the cloud server, and at the same time, can perform message parsing on the first control instruction and the second control instruction, and the serial interface module can be used to forward the first control instruction or the second control instruction to the processor so that the processor can execute the first control instruction or the second control instruction.

[0076] Reference Figure 2 In some other embodiments, S103 may specifically include:

[0077] S1031, obtaining the communication types between the Internet of Things module and the serial interface module and the processor respectively;

[0078] S1032, when the communication type is a CAN bus type, respectively counting a first value of the first message identification number and a second value of the second message identification number;

[0079] S1033, when the second value is less than the first value, determining that the second priority is higher than the first priority;

[0080] S1034: When the second value is greater than the first value, determine that the second priority is lower than the first priority.

[0081] In some embodiments, in determining the priority of the first control instruction and the second control instruction, it can be determined according to the communication type of the Internet of Things module, the serial interface module and the processor module, that is, for different communication types, the determination rule of the priority of the first control instruction and the second control instruction is determined by the communication type.

[0082] In some specific embodiments, taking the communication type of CAN bus as an example, in CAN bus communication, the priority of each control instruction can be determined by the character length of the first message identification number and the second message identification number.

[0083] Specifically, the first value of the first message identification number and the second value of the second message identification number can be counted, and then the first value and the second value can be compared. In the CAN bus, the smaller the length of the message identification number, the higher the priority. Therefore, when the second value is less than the first value, the second priority of the second control instruction is higher than the first priority of the first control instruction. On the contrary, when the second value is greater than the first value, the first priority is higher than the second priority.

[0084] In addition, it is worth noting that when the first value and the second value are equal, it means that the first control instruction and the second control instruction are at the same priority. At this time, the priority can be determined according to the order of timestamps, that is, the timestamp of the vehicle-mounted terminal receiving the first control instruction is earlier than the timestamp of receiving the second control instruction. At this time, the first priority of the first control instruction is higher than the second priority of the second control instruction.

[0085] In some other embodiments, the communication types of the physical network module, serial port communication module and processor may also adopt other bus types. There are different priority rules for each bus type, which can be determined by referring to the priority rules of the corresponding bus, and will not be elaborated here.

[0086] In some other embodiments, the second message may further include an instruction type used to characterize the second control instruction. Before S103, the method may further include:

[0087] Determining whether the instruction type of the second control instruction is a non-interruptible type;

[0088] When the instruction type of the second control instruction is a non-interruptible type, obtaining a first state identifier of the first control instruction;

[0089] Based on the first state identifier, determining a first execution state of the first control instruction;

[0090] When the first execution status is determined to be the executing status, sending the first execution status to the server;

[0091] When the first execution status is determined to be an execution completed status or an unexecuted status, obtaining a calling status of the serial interface module for the first message;

[0092] When the calling state is calling completed or calling in progress, stopping the serial interface module from calling the first message and deleting the first message;

[0093] Calling the second message to enable the processor to execute the second control instruction;

[0094] When the instruction type of the second control instruction is an interruptible type, S103 is executed.

[0095] In this embodiment, before determining the priorities of the first control instruction and the second control instruction, it is also necessary to determine the instruction type of the second control instruction, and to determine whether the second control instruction can be executed by referring to different instruction types.

[0096] Specifically, in the second message, a variable may be set to characterize the instruction type of the second control instruction. For example, the instruction type may be represented by a variable value in the second message, such as 0 for an interruptible type and 1 for a non-interruptible type.

[0097] When the instruction type of the second control instruction is a non-interruptible type, the first state identifier of the first control instruction can be obtained, and then the first execution state of the first control instruction can be determined based on the first state identifier. For example, in the vehicle-mounted terminal, a variable "Breakflag" can be set in the first message to represent the first execution state of the first control instruction. The value corresponding to Breakflag represents the first execution state, for example, 0 represents an execution state of not being executed or completed, and 1 represents an execution state being executed.

[0098] The first execution state of the first control instruction is determined by identifying the value of the above variable. In some embodiments, when the first control instruction is determined to be in the execution state, the vehicle terminal can send the first execution state to the server, so that the server displays the first execution state to the control terminal and reminds the user of the instruction being executed by the vehicle terminal.

[0099] In some other embodiments, when the first execution status is determined to be completed or not executed, it means that the vehicle-mounted terminal is in an idle period and the first control instruction may not be executed due to delay, so it is also necessary to obtain the calling status of the serial interface module for the first message. When the calling status is determined to be completed or calling, it is necessary to stop the serial interface module from calling the first message, delete the first message, and store the second message in the serial interface module to prepare for the processor to execute the second control instruction.

[0100] In some other embodiments, when the call status is determined to be not called, a busy prompt message is returned to the server.

[0101] In this embodiment, when the instruction type of the second control instruction is an interruptible type, it means that the second control instruction and the first control instruction are both asynchronous commands, and the control instruction to be executed can be determined by judging the priority of the first control instruction and the second control instruction.

[0102] In some other embodiments, when the instruction type of the second control instruction is an interruptible type, the method may further include:

[0103] When the first message identification number and the second message identification number are consistent and the first execution state is being executed, the first state identifier is adjusted to a second state identifier, and the second state identifier is used to indicate that the first execution state corresponding to the first control instruction is a suspended execution state; and / or;

[0104] When the first message identification number and the second message identification number are consistent and the first execution state is a suspended execution state, the second state identifier is adjusted to a third state identifier, and the third state identifier is used to indicate that the first execution state corresponding to the first control instruction is changed from a suspended execution state to a resumed execution state.

[0105] In some other embodiments, the first message further includes a first instruction type for characterizing the real-time performance of the first control instruction, and the second message further includes a second instruction type for characterizing the real-time performance of the second control instruction. S103 may further include:

[0106] In the case where the first instruction type is determined to be a synchronization instruction, the first priority is higher than the second priority;

[0107] In the case where the second instruction type is determined to be a synchronization instruction, the second priority is higher than the first priority.

[0108] In this embodiment, during the process of remote control of the vehicle, the vehicle terminal needs to execute some real-time control instructions to ensure the execution of the remote control.

[0109] Therefore, when determining the priority of the first control instruction and the second control instruction, it is necessary to consider the instruction type of the control instruction. When the first instruction type is a synchronous instruction, it means that the first control instruction needs to be executed in real time, and the vehicle-mounted terminal needs to return the execution result to the control terminal. Therefore, regardless of whether the second instruction type of the second control instruction is a synchronous instruction, the first priority is higher than the second priority.

[0110] It is worth noting that, when the instruction type of the first control instruction is a synchronous instruction, even if the second control instruction is a synchronous instruction, at this time the first priority is higher than the second priority, the first control instruction is executed, and the first control instruction cannot be interrupted.

[0111] Correspondingly, if the first instruction type of the first control instruction is determined to be an asynchronous instruction and the second instruction type of the second control instruction is determined to be a synchronous instruction, the second priority is higher than the first priority. At this time, regardless of whether the first control instruction is executed, an interrupt is required.

[0112] As an example, the control instructions corresponding to the basic functions to ensure the operation of the vehicle can be set as synchronous instructions, and the remaining additional functions can be set as asynchronous instructions. For example, turning off the engine and locking the vehicle can be set as synchronous instructions, and parking and searching for the vehicle can be set as asynchronous instructions.

[0113] In some other embodiments, before S103, the following steps may also be included:

[0114] Counting the length value of the second message identification number;

[0115] When the length value is greater than the preset length, the preset prompt information is transmitted to the server.

[0116] In this embodiment, since the second control instruction may be sent through the cloud server, it may be interfered by noise, which may affect the second message of the second control instruction, causing the length value to be greater than the preset length. At this time, it means that the second control instruction is wrong, and it is necessary to transmit preset prompt information to the server. The preset prompt information is used to prompt that the second control instruction has an error, so as to remind the user.

[0117] S104: When the second priority level corresponding to the second control instruction is higher than the first priority level corresponding to the first control instruction, interrupt the first control instruction.

[0118] In this embodiment, when the second priority is higher than the first priority, it means that the second control instruction needs to be executed at this time, but in order to reduce the impact of the first control instruction on the second control instruction, the first control instruction can be interrupted at this time.

[0119] It is worth noting that no matter which control instruction is executed, the time period from receiving the control instruction to completing the execution of the control instruction can be divided into three stages: preparing for execution, executing, and completing execution. No matter which stage the first control instruction is in among the three stages, the execution of the first control instruction must be interrupted.

[0120] S105, executing the second control instruction to obtain an execution result.

[0121] In some embodiments, after determining the control instruction that needs to be executed, the processor reads the corresponding message to execute the corresponding control instruction. For example, when the second priority of the second control instruction is higher than the priority of the first control instruction, the processor executes the second control instruction and obtains the execution result, and then transmits the execution result to the server through the serial interface module and the physical network module, so that the user can understand the execution result of the control instruction through the control terminal.

[0122] In some other embodiments, the second control instruction may include multiple stage commands, the second message may include a third message, and when the instruction type of the second control instruction is determined to be an interruptible type, and the second priority corresponding to the second control instruction is higher than the first priority corresponding to the first control instruction, S105 may include:

[0123] Obtaining the number of interruptions of the second control instruction;

[0124] In the case where the interruption is the first time;

[0125] The third message corresponding to the current stage command is stored in the serial interface module, and the number of interruptions is updated;

[0126] Calling the third message to enable the processor to execute the current stage command;

[0127] After the execution of the multiple stage commands is completed, the execution result of the second control instruction is obtained.

[0128] In this embodiment, when it is determined that the second control instruction is to be executed, since the second control instruction is a multi-stage command, during the execution of the second control instruction, the execution of the second control instruction can only be indicated as completed after the multi-stage commands are normally executed.

[0129] In some other embodiments, the second message may include a fourth message, and when the number of interruptions is not the first time, the method may further include:

[0130] Clearing the third message of the current stage command stored in the serial interface module;

[0131] After a preset delay period, storing a fourth message corresponding to the next stage command;

[0132] In the serial interface module, the fourth message is called to enable the processor to execute the next stage command and update the number of interruptions.

[0133] In this embodiment, since the second control instruction has multiple stage commands, it is necessary to determine which stage command to execute when executing the second control instruction. In this embodiment, the stage command to be executed can be determined by judging the number of interruptions of the second control instruction.

[0134] It is worth noting that, in the case where the second control instruction includes multiple stage commands, the second message may include a message corresponding to each stage command, that is, when sending the second control instruction, the messages corresponding to the multiple stage commands may be packaged into one second message and sent together to the serial interface module, or the messages corresponding to each stage command may be sent separately.

[0135] For example, with respect to the second control instruction for automatic parking, automatic parking may include three stage commands: start parking, pause parking, and resume parking. When executing the stage command for start parking, the third message corresponding to start parking may be sent separately to execute the stage command for start parking, or the second message corresponding to parking may be directly sent, wherein the second message includes the third message corresponding to start parking, the fourth message corresponding to pause parking, and the fifth message corresponding to resume parking. Then, by responding to the stage command selected by the user, the message consistent with the selected stage command is directly retrieved from the second message to execute the corresponding stage command.

[0136] For example, taking automatic car search as the first control instruction and automatic parking as the second control instruction, when the first control instruction of automatic car search is being executed, the user sends the second control instruction of automatic parking. At this time, it is necessary to interrupt the automatic car search and start executing the automatic parking command.

[0137] In this process, automatic parking can be divided into three stages of commands, namely, start parking, pause parking and resume parking. In the process of executing the first stage command of start parking, since it is the first interruptible command, it is necessary to delete the first message stored in the serial interface module, that is, the first message corresponding to the automatic vehicle search. Then, after a preset delay period, the third message corresponding to start parking is stored. Then, in the serial interface module, the first state identifier is modified to the second state identifier in the second message. The second state identifier is used to indicate the start of the first stage command of the second control instruction. Since the first stage command has been started, the number of interrupts of the second control instruction needs to be updated at this time. For example, the number of interrupts can be adjusted to 2.

[0138] As an example, the preset delay period may be 100 ms, and the initial interruption number of the second control instruction is 1.

[0139] In this embodiment, when executing the first stage command of start parking, the user sends the second stage command of pause parking. At this time, since the number of interruptions is not the first time, it is necessary to interrupt the first stage command of start parking, that is, to clear the third message corresponding to the first stage command of start parking, and then store the fourth message corresponding to the second stage command of pause parking in the serial interface module, update the number of interruptions to 3 times, and call the fourth message at the same time to start executing the pause parking command.

[0140] When executing the pause parking command, the user now issues the third stage command of resuming parking. At this time, since the number of interruptions is 3 times, it is necessary to interrupt the second stage command of pause parking, and then store the fifth message corresponding to resuming parking in the serial interface module, update the number of interruptions to 4 times, and call the message corresponding to resuming parking at the same time, and start executing the command of resuming parking until the automatic parking is completed and the second control instruction is executed, and the execution result corresponding to the successful execution is obtained.

[0141] To facilitate understanding of the above method, a specific example is used for explanation.

[0142] In this example, taking the case where the first control instruction is automatic car search and the second control instruction is automatic parking, the automatic car search instruction and the automatic parking instruction are first obtained. At this time, it is determined whether the format of the second message corresponding to the automatic parking instruction is correct, that is, whether the Buff tag in the format is empty. If it is empty, an invalid format is returned to the user. If it is not empty, it is also necessary to determine whether the length value of the second message identification number is greater than the preset length. If it is greater than the preset length, a preset prompt message is transmitted to the server. If it is not greater than the preset length, the second instruction type of the automatic parking instruction can be determined. If the second instruction type of the automatic parking is a synchronous instruction and the first instruction type of the automatic car search is an asynchronous instruction, it can be determined that the second priority of the automatic parking is higher than the first priority of the automatic car search, and the automatic parking instruction is executed.

[0143] If the second instruction type of automatic parking is an asynchronous instruction and the first instruction type of automatic car search is a synchronous instruction, it is necessary to continue to determine whether the instruction type of automatic parking is an interruptible type. If the instruction type of automatic parking is a non-interruptible type, it is necessary to determine whether the execution status of automatic car search is 1, that is, whether automatic car search is being executed. If automatic car search is being executed, the current command status is sent to the server. If the instruction of automatic car search has been executed or not executed at this time, the calling status of the serial interface module for the first message corresponding to the automatic car search can be obtained. When the calling status is not called, the information that the serial interface module is busy can be returned to the server. When the calling status is completed or calling, the serial interface module stops calling the first message and deletes the first message. Then the serial interface module calls the third message corresponding to the automatic parking so that the processor executes the automatic parking instruction.

[0144] In this example, the execution of the first control instruction or the second control instruction can be determined by the instruction type. After determining the control instruction to be executed by the instruction type, it is also necessary to determine the priority of the second control instruction and the first control instruction. If the second priority of automatic parking is lower than the first priority of automatic car search, the command priority of automatic parking is returned to the server at this time, and the control instruction of automatic car search continues to be executed. In this example, the second priority of automatic parking is set higher than the first priority of automatic car search.

[0145] In the case where it is determined that the second priority of automatic parking is higher than the first priority of automatic vehicle search, it can be determined that the control instruction of automatic parking is to be executed.

[0146] In the process of executing the control command of automatic parking, since automatic parking can be divided into three stage commands of starting parking, pausing parking and resuming parking, when executing automatic parking, the number of interruptions of automatic parking can be obtained to determine which stage command is currently executed. For example, the number of interruptions corresponding to driving parking is 1, which is the first interruption. At this time, it is necessary to delete the first message corresponding to automatic car search, and then store the third message corresponding to starting parking in the serial interface module to execute the command of starting parking, and update the number of interruptions to 2. In the case of executing the control command of starting parking, the user issues the stage command of pausing parking. Since the number of interruptions is not the first time, it is necessary to interrupt the execution of the stage command of starting parking, and store the fourth message corresponding to pausing parking in the serial interface module to execute the stage command of pausing parking; in the process of executing the stage command of pausing parking, the user issues the stage command of resuming parking. At this time, the execution of the stage command of pausing parking can be interrupted, and then the fifth message corresponding to resuming parking is stored in the serial interface module to execute the stage command of resuming parking, until parking is completed, the execution of the second control command is completed, and the execution result is obtained.
