Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle control, and particularly relates to a method for a vehicle end to self-learn and establish a TSP long connection in different time periods. Background Art

[0002] Remote control via a mobile phone APP for new energy vehicles is an essential basic function. The entire process realizes specific remote control functions through APP>TSP>vehicle end>TSP>APP, including the following functions: 1. Remote control of air conditioning on and off; 2. Remote control of unlocking and locking, and window opening and closing; 3. Remote seat ventilation and heating; 4. Remote vehicle status query, etc. In the prior art, when the vehicle is in the wake-up state, the response speed of remote control execution is very fast, and the user acceptance is high; when the vehicle is in the sleep state, the remote control response is slow, and the user experience is poor. The TBOX wakes up regularly. If the wake-up is too frequent, the power consumption of the vehicle end is relatively large, which easily leads to the risk of power failure; if the TBOX wakes up regularly, the platform load is relatively large, which easily causes abnormalities in the platform. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for a vehicle end to self-learn and establish a TSP long connection in different time periods. The long connection scheme can greatly improve the response speed; according to different vehicle usage habits of users, establish a long connection between the vehicle end and the TSP in different time periods to keep the vehicle end with low power consumption; different vehicles establish long connections in different time periods, and the wake-up intervals are also different within this time period, so as to achieve the maximum platform load balancing and not cause platform problems.

[0004] To solve the above technical problems, the technical solution of the present invention is: a method for a vehicle end to self-learn and establish a TSP long connection in different time periods, including:

[0005] Establish a long connection between the vehicle end and the vehicle remote service provider TSP;

[0006] Control the opening and closing of the long connection between the vehicle end and the TSP according to preset time period information;

[0007] Dynamically adjust the time period information of the opening and closing of the long connection between the vehicle end and the TSP through self-learning;

[0008] Execute remote control instructions from the mobile phone APP through the long connection between the vehicle end and the TSP.

[0009] In the preset time period information, the preset time period is default set to the peak vehicle usage time periods, specifically including 6:00 - 8:00, 12:00 - 14:00, and 17:00 - 19:00.

[0010] The method for dividing time periods is as follows: The 24 hours of a day are evenly divided into 24 time periods per hour. The long connection between the vehicle end and TSP is opened or closed in units of time periods. The time periods and the identifiers indicating whether the corresponding long connections are opened are saved inside the TBOX of the vehicle end as time period information, and the TBOX establishes a long connection with TSP according to the dynamically adjusted and updated time period information.

[0011] The method for dynamically adjusting the time period information through self-learning is as follows: The TBOX continuously monitors and records the user's vehicle usage habits to determine the time periods when the user has the need to use the vehicle, and dynamically adjusts and updates the time period information according to the judgment results.

[0012] The user's vehicle usage habits for determining that the user has the need to use the vehicle at least include remote control operations and unlocking operations; the unlocking operations include, but are not limited to, unlocking the vehicle with a physical key, unlocking the vehicle with an NFC key, and unlocking the vehicle with a Bluetooth key.

[0013] The method for determining the time periods when the user has the need to use the vehicle and dynamically adjusting and updating the time period information according to the judgment results is as follows:

[0014] When it is detected that the vehicle end receives a remote control operation or an unlocking operation instruction within a certain time period, it is determined that the user has the need to use the vehicle during this time period. This time period is used as the default time period for opening the long connection and the time period information is dynamically adjusted and updated, and a long connection is established according to the updated time period information;

[0015] When the vehicle end does not receive a remote control operation or an unlocking operation instruction within the default time period for opening a certain long connection for more than 3 days, it is determined that the user does not have the need to use the vehicle during this time period. This time period is used as the default time period for closing the long connection and the time period information is dynamically adjusted and updated, and a long connection is established according to the updated time period information.

[0016] The steps for executing the remote control instruction from the mobile APP through the long connection between the vehicle end and TSP are specifically as follows:

[0017] The mobile APP sends the remote control instruction to the TSP background;

[0018] When the long connection between the vehicle end and TSP is in the active state, the TSP always maintains the Message Queuing Telemetry Transport (MQTT) connection, sends the remote control instruction to the vehicle end, and receives the feedback response in real time;

[0019] The TBOX sends the corresponding instruction to the corresponding execution end controller of the vehicle end to execute the remote control command;

[0020] The vehicle controller feeds back the execution result of the remote control instruction to the TBOX;

[0021] The TBOX sends the feedback result to the TSP background through the long connection;

[0022] The TSP background sends the remote control execution result to the mobile APP to update the execution result status of the mobile APP.

[0023] When the long connection between the vehicle end and the TSP is in the active state, the TBOX sends a heartbeat signal to the TSP at a preset time interval and receives a heartbeat response from the TSO.

[0024] There is also provided a computer device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the steps of the method described in any one of the above are implemented.

[0025] There is also provided a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the method described in any one of the above are implemented.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] By establishing a long connection between the vehicle end and the TSP, the present invention can greatly improve the remote control response speed of the mobile APP in the vehicle's sleep state. While establishing the long connection, the low power consumption of the vehicle end is maintained to avoid the risk of power depletion. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The technical solution of the present invention is as follows:

[0033] Embodiment 1:

[0034] A method for the vehicle end to establish a long connection with the TSP through self-learning in different time periods, as Figure 1 shown, includes:

[0035] S1. Establish a long connection between the vehicle end and the automotive remote service provider TSP;

[0036] S2. Control the opening and closing of the long connection between the vehicle end and TSP according to the preset time period information;

[0037] S3. Dynamically adjust the time period information for opening and closing the long connection between the vehicle end and TSP through self-learning;

[0038] S4. Execute the remote control instructions from the mobile APP through the long connection between the vehicle end and TSP.

[0039] Specifically include:

[0040] 1) Long connection establishment process

[0041] After the vehicle end and TSP establish a long connection, the remote control operation flow chart is as Figure 2 shown:

[0042] The remote control execution steps are as follows:

[0043] 1. The mobile APP sends the remote instruction to the TSP background;

[0044] 2. In the activated state of the long connection, TSP always maintains the MQTT connection, requests the remote control instruction operation from the vehicle end, and quickly receives the remote control response.

[0045] 3. The T-BOX sends the corresponding instruction to the corresponding execution end controller of the vehicle end to execute the control command;

[0046] 4. The vehicle controller feeds back the execution result of the remote control command to the T-BOX;

[0047] 5. The T-BOX feeds back the result to the TSP through the long connection channel;

[0048] 6. The TSP background returns the control execution result to the mobile APP to update the execution result status of the mobile APP. When the long connection is established and in the sleep state, the internal timer of the Tbox wakes up actively every

[0049] Keepalive_Period_TBOX (calibratable) mins to send a heartbeat to the TSP and receive the heartbeat response from the TSP. The software resets the timer after each timing timeout.

[0050] 2) Establish a long connection in different time periods

[0051] Divide the 24 hours of a day into 24 time periods per hour. Use the time period as the unit to open or close the TSP long connection. Save the time period and the flag indicating whether the corresponding long connection is open in the in-vehicle terminal Tbox. The Tbox establishes a long connection according to this time period information. When the vehicle leaves the factory, the default long connection opening time periods are set to the three peak vehicle usage time periods in the morning, noon, and evening (configurable).

[0052] Morning: 6:00 - 8:00, open the long connection;

[0053] Noon: 12:00 - 14:00, open the long connection;

[0054] Evening: 17:00 - 19:00, open the long connection;

[0055] The time period table is shown in Table 1. The first row, 0 - 23, represents the 24 time periods of a day. The second row is the long connection flag. 0 indicates that the long connection does not need to be opened or the long connection is to be exited, and 1 indicates that the long connection needs to be opened.

[0056] Table 1

[0057] Time period 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Long connection identifier 0 0 0 0 0 0 1 1 0 0 0 0 1 1 0 0 0 1 1 0 0 0 0 0

[0058] Whether to open or close the long connection within each time period is updated irregularly and takes effect immediately according to the actual vehicle usage needs of the user. At the same time, the updated data is stored in the internal memory of the vehicle - end Tbox, and the Tbox establishes a long connection with the TSP according to the new time period information.

[0059] In the preset time period information, the preset time periods are default set to the peak vehicle usage time periods, specifically including 6:00 - 8:00, 12:00 - 14:00, and 17:00 - 19:00.

[0060] The method of dividing time periods is as follows: Divide the 24 hours of a day into 24 time periods on average per hour. Use the time period as the unit to open or close the long connection between the vehicle - end and the TSP. Save the time period and the flag indicating whether the corresponding long connection is open in the vehicle - end TBOX as time period information. The TBOX establishes a long connection with the TSP according to the dynamically adjusted and updated time period information.

[0061] 3) Self - learning and updating the long connection time period

[0062] The in - vehicle terminal Tbox continuously monitors the user's vehicle usage needs, including remote control operations, and unlocking the vehicle operations with physical keys, NFC keys, or Bluetooth keys, etc., to judge in which time period the user may have vehicle usage needs or no needs, and dynamically learn and update the local long connection time period table, so as to achieve that different vehicles establish long connections in different time periods, and vehicles that have not been used for a long time do not establish long connections, reducing resource occupancy and balancing the platform load. The specific method is as followsFigure 3 as shown

[0063] 1. If remote control operations are detected within a certain time period, as well as vehicle unlocking operations using a physical key, NFC key, Bluetooth key, etc., it is considered that the vehicle user has a need to use or access the vehicle during this time period. Update the long connection identifier for this time period to 1 locally and establish a long connection according to the updated time period data.

[0064] 2. If there are no remote control or unlocking operations for more than 3 consecutive days within a certain time period, it is considered that there is no need to use the vehicle during this time period. Update the long connection identifier for this time period to 0 locally and establish a long connection according to the updated time period data.

[0065] 3. Wake up randomly once between every 10 - 15 minutes during the long connection time period to keep the heartbeat alive.

[0066] The method for dynamically adjusting the time period information through self - learning is as follows: Continuously monitor and record the user's vehicle - using habits through TBOX to determine the time periods when the user has a need to use the vehicle, and dynamically adjust and update the time period information according to the judgment results.

[0067] The user's vehicle - using habits for judging that the user has a need to use the vehicle at least include remote control operations and unlocking operations; unlocking operations include, but are not limited to, unlocking the vehicle with a physical key, unlocking the vehicle with an NFC key, and unlocking the vehicle with a Bluetooth key.

[0068] The method for judging the time periods when the user has a need to use the vehicle and dynamically adjusting and updating the time period information according to the judgment results is as follows:

[0069] When it is detected that the vehicle terminal receives a remote control operation or unlocking operation instruction within a certain time period, it is judged that the user has a need to use the vehicle during this time period. Use this time period as the default time period for opening the long connection, dynamically adjust and update the time period information, and establish a long connection according to the updated time period information;

[0070] When the vehicle terminal does not receive a remote control operation or unlocking operation instruction for more than 3 days within the default time period for opening a certain long connection, it is judged that the user does not have a need to use the vehicle during this time period. Use this time period as the default time period for closing the long connection, dynamically adjust and update the time period information, and establish a long connection according to the updated time period information.

[0071] The steps for executing the remote control instruction from the mobile APP through the long connection between the vehicle terminal and TSP are specifically as follows:

[0072] The mobile APP sends the remote control instruction to the TSP background;

[0073] When the long connection between the vehicle end and the TSP is in the active state, the TSP always maintains the Message Queuing Telemetry Transport (MQTT) connection, sends remote control instructions to the vehicle end, and receives feedback responses in real time.

[0074] The TBOX sends corresponding instructions to the corresponding execution end controller of the vehicle end to execute the remote control command.

[0075] The vehicle controller feeds back the execution result of the remote control instruction to the TBOX.

[0076] The TBOX sends the feedback result to the TSP background through the long connection.

[0077] The TSP background sends the remote control execution result to the mobile APP to update the status.

[0078] When the long connection between the vehicle end and the TSP is in the active state, the TBOX sends a heartbeat signal to the TSP at a preset time interval and receives a heartbeat response from the TSO.

[0079] The technical solution of the embodiment of the present invention can bring the following beneficial effects:

[0080] 1. Establishing a long connection between the vehicle end Tbox and the TSP can greatly improve the remote control response speed of the mobile APP in the vehicle's sleep state, from more than ten seconds to within 5 seconds.

[0081] 2. While establishing a long connection, keep the vehicle end with low power consumption to avoid the risk of power depletion.

[0082] 3. Each vehicle activates and establishes a long connection at different time periods and wakes up to send heartbeats at different time intervals, which can greatly reduce the load on the platform side and achieve the effect of load balancing.
