Description

Technical Field

[0001] The present invention relates to vehicle control technology, and in particular to a vehicle data transmission control method, a storage medium and a vehicle. Background Art

[0002] With the continuous development of new energy vehicle technology, cars have more and more functions. At the same time, real-time monitoring of various functional modules of cars is becoming more and more important. Generally speaking, the monitoring of various information of cars is uploaded to TBOX through the processor of the vehicle domain controller, and then transmitted to the server through TBOX. The driver obtains the real-time functional information of the whole vehicle from the server through the mobile client (i.e. mobile APP). On the one hand, most traditional cars can only obtain real-time functional information of the whole vehicle through the driver. On the other hand, this monitoring method relies on network base station services. When the car is parked in or driving to an area with poor or no network status, the user cannot obtain real-time vehicle status function information in time. Affecting the user experience.

Undoubtedly, the technical solution disclosed in the above patent document is a beneficial attempt in the technical field, but in this technical solution, the corresponding car setting parameters are pre-stored for different drivers, and the car equipment can be automatically adjusted for the car setting parameters, and the corresponding real-time function information and function control authority of the whole vehicle cannot be provided to the driver and the passenger. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a vehicle data transmission control method, storage medium and vehicle, which can enable passengers to obtain some real-time status parameters of the whole vehicle within the permitted authority and control some functions of the whole vehicle, thereby improving the passenger experience and ensuring data transmission between the vehicle domain controller and the mobile terminal when the network status is not good.

[0005] A vehicle data transmission control method in the present invention comprises the following steps:

[0006] S1. When the car is started, the vehicle domain controller automatically obtains the Bluetooth and WIFI connection permissions of the driver's mobile terminal, the vehicle domain controller communicates with the driver's mobile terminal, and then executes step S2;

[0007] S2, determine whether there are passengers in the vehicle, if there are passengers, execute step S3, if there are no passengers, execute step S7;

[0008] S3, the vehicle domain controller applies to the passenger mobile terminal for Bluetooth and WIFI connection permissions, and then executes step S4;

[0009] S4, determine whether the passenger agrees that the vehicle domain controller obtains permission, if the passenger agrees, execute step S5, if the passenger disagrees, execute step S7;

[0010] S5, the vehicle domain controller communicates with the driver's mobile terminal and the passenger's mobile terminal at the same time, and then executes step S6;

[0011] S6, the driver's mobile terminal and the passenger's mobile terminal simultaneously transmit data to the vehicle domain controller;

[0012] S7. The driver's mobile terminal transmits data with the vehicle domain controller.

[0013] Further, in step S6 or step S7, there are two forms of data transmission. The first is that the vehicle domain controller sends data to the driver's mobile terminal or the passenger's mobile terminal, and the second is that the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller.

[0014] Further, when data transmission is performed in step S6 or step S7, the following steps are included:

[0015] A1. The data acquisition module of the vehicle domain controller collects the real-time status parameters of the vehicle, and then executes step A2;

[0016] A2. The network detection module of the vehicle domain controller compares the current network speed transmission value with the first expected setting value; if the current network speed transmission value is higher than the first expected setting value, step A3 is executed; if the current network speed transmission value is lower than the first expected setting value, step A4 is executed;

[0017] A3. The network is currently in good condition. The wireless network transmission module of the vehicle domain controller communicates with the driver's mobile terminal and the passenger's mobile terminal through the server. At this time, network data transmission is used;

[0018] A4. The control module of the vehicle domain controller controls the car to turn on the Bluetooth module of the vehicle domain controller, and enables the Bluetooth module to communicate with the driver's mobile terminal and the passenger's mobile terminal; or the control module of the vehicle domain controller controls the car to turn on the WIFI module of the vehicle domain controller, and enables the WIFI module to establish a local area network with the driver's mobile terminal and the passenger's mobile terminal to transmit data, and then execute step A5;

[0019] A5. The network detection module of the vehicle domain controller compares the current network speed transmission value with the second expected setting value; if the current network speed transmission value is lower than the first expected setting value and higher than the second expected setting value, execute step A6; if the current network speed transmission value is lower than the second expected setting value, execute step A7;

[0020] A6. If the network speed is slow or intermittent, use WIFI data transmission and network data transmission at the same time; or use Bluetooth data transmission and network data transmission at the same time, and then execute step A8;

[0021] A7: Currently in no network state, disconnect from the network, use only WIFI data transmission or Bluetooth data transmission, and then execute step A8;

[0022] A8. The driver's mobile terminal stores the vehicle status data in real time, and when the current network speed transmission value is higher than the first preset value, transmits the data to the server for backup.

[0023] Further, in step A6, when using WIFI data transmission and network data transmission, the data processing module of the vehicle domain controller compares the network data transmission speed with the WIFI data transmission speed, and determines whether the network data transmission speed is faster than the WIFI data transmission speed. If it is judged as yes, the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller using network data transmission, and the vehicle domain controller uses WIFI data transmission when sending data to the driver's mobile terminal or the passenger's mobile terminal. If it is judged as no, the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller using WIFI data transmission, and the vehicle domain controller uses network data transmission when sending data to the driver's mobile terminal or the passenger's mobile terminal.

[0024] Further, in step A6, when using Bluetooth data transmission and network data transmission, the data processing module of the vehicle domain controller compares the network data transmission speed with the Bluetooth data transmission speed, and determines whether the network data transmission speed is faster than the Bluetooth data transmission speed. If it is judged as yes, the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller using network data transmission, and the vehicle domain controller uses Bluetooth data transmission when sending data to the driver's mobile terminal or the passenger's mobile terminal. If it is judged as no, the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller using Bluetooth data transmission, and the vehicle domain controller uses network data transmission when sending data to the driver's mobile terminal or the passenger's mobile terminal.

[0025] Furthermore, the data sent by the vehicle domain controller to the driver's mobile terminal are real-time status parameters of the vehicle. The driver can preset the passenger's information access rights. The data sent by the vehicle domain controller to the passenger's mobile terminal are some of the real-time status parameters of the vehicle that the driver sets to allow the passenger to know.

[0026] Furthermore, the real-time status parameters of the whole vehicle include vehicle driving information, vehicle system information, comfort system information, external visual monitoring information, in-vehicle air-conditioning information, vehicle seat information, vehicle condition inspection and in-vehicle entertainment system control information, and some of the real-time status parameters of the whole vehicle include one or more of vehicle driving information, vehicle system information, comfort system information, external visual monitoring information, in-vehicle air-conditioning information, vehicle seat information, vehicle condition inspection and in-vehicle entertainment system control information.

[0027] Furthermore, the data sent by the driver's mobile terminal to the vehicle domain controller are function control parameters for controlling the entire vehicle. The driver can preset passenger function control permissions. The data sent by the passenger's mobile terminal to the vehicle domain controller are partial function control parameters set by the driver to allow passengers to control.

[0028] Furthermore, the functional control parameters include seat control parameters, air conditioning control parameters and entertainment music control parameters, and the partial functional control parameters include one or more of the seat control parameters, air conditioning control parameters and entertainment music control parameters.

[0029] The present invention discloses a storage medium, on which a vehicle data transmission program is stored. When the vehicle data transmission program is executed by a processor, the vehicle data transmission control method as described above can be implemented.

[0030] A vehicle disclosed in the present invention comprises the storage medium as described above.

[0031] The beneficial effects of the present invention are:

[0032] 1. The present invention enables the passenger mobile terminal to access the vehicle domain controller, so that the passenger mobile terminal can transmit data with the vehicle domain controller, so that the passenger can also obtain some real-time status parameters of the vehicle within the permission and can control some functions of the vehicle, thereby improving the passenger's user experience;

[0033] 2. The present invention can realize the communication between the vehicle domain controller and the server through different modules of the vehicle domain controller, realize the communication between the vehicle domain controller and the driver's mobile terminal and the passenger's mobile terminal in different ways, and realize the control of the vehicle domain controller on the vehicle and data collection;

[0034] 3. The present invention uses WIFI data transmission and network data transmission or Bluetooth data transmission and network data transmission at the same time when the network speed is slow or the network is intermittent, so as to realize data transmission between the vehicle domain controller and the mobile terminal when the network speed is slow or the network is intermittent. It also uses WIFI data transmission or Bluetooth data transmission when there is no network to realize data transmission between the vehicle domain controller and the mobile terminal when there is no network. Moreover, when the network speed is slow, the network is intermittent or there is no network, the mobile terminal has a certain data processing capability and assumes part of the server's functions. The driver's mobile terminal records the current real-time status parameters of the vehicle, and uploads and backs up the data to the server when driving to an area with better network status, thus solving the problem that the monitoring of the vehicle status parameters is interrupted and data cannot be transmitted when the network status is poor.

[0035] 4. The present invention divides data transmission forms into two types. The first type is that the vehicle domain controller sends data to the driver's mobile terminal or the passenger's mobile terminal, and the second type is that the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller. When the network speed is slow or intermittent, the two data transmission forms can be transmitted through different transmission methods through the data processing module, and the data sent from the driver's mobile terminal or the passenger's mobile terminal to the vehicle domain controller can be transmitted in a faster data transmission mode.

[0041] like Figure 1-Figure 2 As shown, a vehicle data transmission control method in this embodiment includes the following steps:

[0042] S1. When the car is started, the vehicle domain controller automatically obtains the Bluetooth and WIFI connection permissions of the driver's mobile terminal, the vehicle domain controller communicates with the driver's mobile terminal, and then executes step S2;

[0043] S2, determine whether there are passengers in the vehicle, if there are passengers, execute step S3, if there are no passengers, execute step S7;

[0044] S3, the vehicle domain controller applies to the passenger mobile terminal for Bluetooth and WIFI connection permissions, and then executes step S4;

[0045] S4, determine whether the passenger agrees that the vehicle domain controller obtains permission, if the passenger agrees, execute step S5, if the passenger disagrees, execute step S7;

[0046] S5, the vehicle domain controller communicates with the driver's mobile terminal and the passenger's mobile terminal at the same time, and then executes step S6;

[0047] S6, the driver's mobile terminal and the passenger's mobile terminal simultaneously transmit data to the vehicle domain controller;

[0048] S7. The driver's mobile terminal transmits data with the vehicle domain controller.

[0049] The mobile terminal can be a mobile phone client. In step S2, the driver can manually select on the mobile terminal to confirm whether there are passengers in the vehicle. When there are passengers and the passenger mobile terminal is connected to the vehicle domain controller, the passenger mobile terminal can transmit data with the vehicle domain controller to enable the passenger to obtain some real-time status parameters of the vehicle within the permitted authority and control some vehicle functions, thereby improving the passenger's user experience.

[0050] In this embodiment, in step S6 or step S7, there are two forms of data transmission: the first is that the vehicle domain controller sends data to the driver's mobile terminal or the passenger's mobile terminal, which enables the driver and the passenger to monitor the vehicle status in real time; the second is that the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller, which enables the driver and the passenger to control the vehicle functions. Figure 2 As shown, the vehicle domain controller includes a control module, a network detection module, a wireless network transmission module, a WIFI module, a Bluetooth module, a signal receiving module, a data acquisition module and a data processing module; the control module is used to control vehicle functions; the network detection module is used to detect the surrounding network environment while the car is driving; the wireless network transmission module is used to communicate with the driver's mobile terminal and the passenger's mobile terminal through the server to realize network data transmission; the WIFI module is used to build a data transmission local area network with the driver's mobile terminal and the passenger's mobile terminal to realize WIFI data transmission; the Bluetooth module is used to communicate with the driver's mobile terminal and the passenger's mobile terminal to realize Bluetooth data transmission; the signal receiving module is used to receive the function control parameters sent by the driver's mobile terminal and the passenger's mobile terminal; the data acquisition module is used to collect the real-time status parameters of the vehicle; the data processing module is used to determine the data allocated to the transmission by the Bluetooth module, the WIFI module and the wireless network transmission module in the state of no network, slow network or intermittent network. Through the different modules of the vehicle domain controller, the vehicle domain controller can communicate with the server, the vehicle domain controller can communicate with the driver's mobile terminal and the passenger's mobile terminal in different ways, and the vehicle domain controller can control the vehicle and collect data. The data processing module can transmit the two data transmission forms (i.e., the vehicle domain controller sends data to the driver's mobile terminal or the passenger's mobile terminal and the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller) using an appropriate data transmission method according to the network status. The specific content will be explained in detail below.

[0051] In this embodiment, Figure 2-Figure 3 As shown, when data transmission is performed in step S6 or step S7, the following steps are included:

[0052] A1. The data acquisition module of the vehicle domain controller collects the real-time status parameters of the vehicle, and then executes step A2;

[0053] A2, the network detection module compares the current network speed transmission value with the first expected setting value; if the current network speed transmission value is higher than the first expected setting value, execute step A3; if the current network speed transmission value is lower than the first expected setting value, execute step A4;

[0054] A3. The network is currently in good condition. The wireless network transmission module of the vehicle domain controller communicates with the driver's mobile terminal and the passenger's mobile terminal through the server. At this time, network data transmission is used;

[0055] A4. The control module of the vehicle domain controller controls the car to turn on the Bluetooth module of the vehicle domain controller, and enables the Bluetooth module to communicate with the driver's mobile terminal and the passenger's mobile terminal; or the control module of the vehicle domain controller controls the car to turn on the WIFI module of the vehicle domain controller, and enables the WIFI module to establish a local area network with the driver's mobile terminal and the passenger's mobile terminal to transmit data, and then execute step A5;

[0056] A5. The network detection module of the vehicle domain controller compares the current network speed transmission value with the second expected setting value; if the current network speed transmission value is lower than the first expected setting value and higher than the second expected setting value, execute step A6; if the current network speed transmission value is lower than the second expected setting value, execute step A7;

[0057] A6. If the network speed is slow or intermittent, use WIFI data transmission and network data transmission at the same time; or use Bluetooth data transmission and network data transmission at the same time, and then execute step A8;

[0058] A7: Currently in no network state, disconnect the network connection, use only WIFI data transmission or Bluetooth data transmission, and then execute step A8;

[0059] A8. The driver's mobile terminal stores the vehicle status data in real time, and when the current network speed transmission value is higher than the first preset value, transmits the data to the server for backup.

[0060] During data transmission, the car may encounter a network environment with slow network speed, intermittent network or no network during driving, which will cause the driver or passenger's mobile terminal to be unable to obtain the real-time status parameters of the whole vehicle and unable to control the vehicle functions in real time. At this time, the present invention uses WIFI data transmission and network data transmission or Bluetooth data transmission and network data transmission at the same time in the slow network speed or intermittent network state to realize the data transmission between the whole vehicle domain controller and the mobile terminal in the slow network speed state or intermittent network state, and uses WIFI data transmission or Bluetooth data transmission in the no network state to realize the data transmission between the whole vehicle domain controller and the mobile terminal in the no network state. In addition, in the slow network speed state, intermittent network state or no network state, the mobile terminal has a certain data processing capability and assumes part of the server's functions. The driver's mobile terminal records the current real-time status parameters of the whole vehicle, and uploads and backs up the data to the server when driving to an area with better network status, which solves the problem that the monitoring of the whole vehicle status parameters is interrupted and data cannot be transmitted when the network status is not good. Among them, WIFI data transmission is achieved by building a data transmission local area network with the driver's mobile terminal and the passenger's mobile terminal through the WIFI module, and Bluetooth data transmission is achieved by using the Bluetooth module to communicate with the driver's mobile terminal and the passenger's mobile terminal. The current network speed transmission value refers to the current data transmission volume per unit time. The first expected setting value and the second expected setting value have different options according to different vehicle models. The first expected setting value refers to the minimum data transmission volume per unit time that can normally transmit the real-time status parameters of the entire vehicle. The second expected setting value can be 20% or 25% of the first expected setting value.

[0061] In this embodiment, in step A6, when using WIFI data transmission and network data transmission, the data processing module of the vehicle domain controller compares the network data transmission speed with the WIFI data transmission speed, and determines whether the network data transmission speed is faster than the WIFI data transmission speed. If it is judged as yes, the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller using network data transmission, and the vehicle domain controller uses WIFI data transmission when sending data to the driver's mobile terminal or the passenger's mobile terminal. If it is judged as no, the driver's mobile terminal or the passenger's mobile terminal sends data to the vehicle domain controller using WIFI data transmission, and the vehicle domain controller uses network data transmission when sending data to the driver's mobile terminal or the passenger's mobile terminal. When the network speed is slow or intermittent, WIFI data transmission and network data transmission are used simultaneously to realize data transmission between the vehicle domain controller and the mobile terminal in the slow or intermittent network state. Since there are two forms of data transmission, the first is that the vehicle domain controller sends data to the driver's mobile terminal or the passenger mobile terminal, and the second is that the driver's mobile terminal or the passenger mobile terminal sends data to the vehicle domain controller, the data processing module can transmit the two data transmission forms through different transmission methods after comparing the network data transmission speed with the WIFI data transmission speed. Moreover, since it is more important for the driver's mobile terminal or the passenger mobile terminal to send data to the vehicle domain controller than for the vehicle domain controller to send data to the driver's mobile terminal or the passenger mobile terminal, the transmission speed and response speed need to be more timely. Therefore, the driver's mobile terminal or the passenger mobile terminal sends data to the vehicle domain controller in a faster data transmission mode.

[0062] In this embodiment, in step A6, when Bluetooth data transmission and network data transmission are used, the data processing module of the vehicle domain controller compares the network data transmission speed with the Bluetooth data transmission speed, and determines whether the network data transmission speed is faster than the Bluetooth data transmission speed. If it is judged as yes, the driver mobile terminal or the passenger mobile terminal sends data to the vehicle domain controller using network data transmission, and the vehicle domain controller uses Bluetooth data transmission when sending data to the driver mobile terminal or the passenger mobile terminal. If it is judged as no, the driver mobile terminal or the passenger mobile terminal sends data to the vehicle domain controller using Bluetooth data transmission, and the vehicle domain controller uses network data transmission when sending data to the driver mobile terminal or the passenger mobile terminal. When the network speed is slow or intermittent, Bluetooth data transmission and network data transmission are used simultaneously to realize data transmission between the vehicle domain controller and the mobile terminal in the slow or intermittent network state. Since there are two forms of data transmission, the first is that the vehicle domain controller sends data to the driver's mobile terminal or the passenger mobile terminal, and the second is that the driver's mobile terminal or the passenger mobile terminal sends data to the vehicle domain controller, the data processing module can transmit the two data transmission forms through different transmission methods after comparing the network data transmission speed with the WIFI data transmission speed. Moreover, since it is more important for the driver's mobile terminal or the passenger mobile terminal to send data to the vehicle domain controller than for the vehicle domain controller to send data to the driver's mobile terminal or the passenger mobile terminal, the transmission speed and response speed need to be more timely. Therefore, the driver's mobile terminal or the passenger mobile terminal sends data to the vehicle domain controller in a faster data transmission mode.

[0063] In this embodiment, the data sent by the vehicle domain controller to the driver's mobile terminal are the real-time status parameters of the vehicle. The driver can preset the information rights of the passengers. The data sent by the vehicle domain controller to the passenger mobile terminal are the real-time status parameters of the vehicle that the driver sets to allow the passengers to know. Specifically, the real-time status parameters of the vehicle include vehicle driving information, vehicle system information, comfort system information, external visual monitoring information, in-vehicle air conditioning information, vehicle seat information, automobile condition inspection, and in-vehicle entertainment system control information. Some real-time status parameters of the vehicle include one or more of vehicle driving information, vehicle system information, comfort system information, external visual monitoring information, in-vehicle air conditioning information, vehicle seat information, automobile condition inspection, and in-vehicle entertainment system control information. The driver can obtain all the real-time status parameters of the vehicle, and the driver can preset the information rights of the passengers so that the passengers can obtain part of the real-time status parameters of the vehicle, for example, the passengers can only obtain the in-vehicle air conditioning information and vehicle seat information.

[0064] In this embodiment, the data sent by the driver's mobile terminal to the vehicle domain controller are function control parameters for controlling the vehicle. The driver can preset the passenger function control authority. The data sent by the passenger's mobile terminal to the vehicle domain controller are partial function control parameters set by the driver to allow the passenger to control. Specifically, the function control parameters include seat control parameters, air conditioning control parameters, and entertainment music control parameters. Partial function control parameters include one or more of seat control parameters, air conditioning control parameters, and entertainment music control parameters. The driver can control all vehicle functions, and the driver can preset the passenger function control authority so that the passenger can have partial functions, for example, the passenger can only control the air conditioning function and entertainment music function.

[0065] A storage medium in this embodiment stores a vehicle data transmission program, and when the vehicle data transmission program is executed by a processor, the vehicle data transmission control method as described above can be implemented.

[0066] A vehicle in this embodiment includes the storage medium as described above.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
