However, when the vehicle power mode is OFF and most of the devices enter the sleep state, the entire vehicle network is in sleep, each ECU and TBOX stop sending/receiving signals, and at this time, the data connection between the vehicle and the background is interrupted, so that the background cannot monitor the real-time state of the vehicle, and therefore, the early warning and monitoring of the risk accident cannot be performed, and the driving safety is affected.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example one
Fig. 1 is a schematic flow chart of a data transmission method for a vehicle according to a first embodiment of the present invention, where the vehicle includes, but is not limited to, a new energy vehicle. As shown in fig. 1, the data transmission method for a vehicle according to the first embodiment may include the following steps:
and S100, controlling an early warning component of the vehicle to enter a preset low-power consumption monitoring mode when the power supply mode of the vehicle is the off mode.
As mentioned in the background section, the vehicle power mode includes an OFF mode (OFF) and an ON mode (ON), which correspond to a power-down state and a power-up state of the vehicle, respectively. In consideration of the fact that a background server (or a background monitoring platform) of the vehicle cannot monitor the real-time state of a key component of the vehicle when the power mode of the vehicle is OFF, the embodiment of the invention particularly configures a low-power consumption monitoring mode of an early warning component of the vehicle.
The early warning component is a component which needs to be monitored by a backend server of the vehicle, and in the embodiment of the invention, the early warning component may include any one or more of the following components of the vehicle and/or an ECU of one or more of the following components: TBOX, gateway, battery, power battery, motor and electrical system. The power battery, the motor and the electric control system are generally called three-electric system, and the three-electric system and the TBOX can be respectively provided with an ECU.
Wherein the low power monitoring mode is configured such that components retain only state monitoring functionality and data transfer functionality corresponding to the backend server. For example, the function of monitoring the battery voltage and the battery capacity is reserved corresponding to the storage battery, and the monitored data about the battery voltage and the battery capacity is transmitted to the background server. It should be noted that the data transmission function of the component corresponding to the background server in the embodiment of the present invention includes a function that the component directly communicates with the background server and a function that the component indirectly communicates with the background server through other components (e.g., TBOX).
The existing vehicle part is only normally in a sleep mode and a wake-up mode, and is normally in the sleep mode when the vehicle power supply mode is OFF, so that the data connection with the background server is interrupted, and the background server cannot acquire part state data to perform safety monitoring and early warning. On the basis of the sleep mode and the wake-up mode, the embodiment of the invention is further provided with a low-power consumption monitoring mode which enables the part to only reserve the state monitoring function and the data transmission function corresponding to the background server, thereby realizing the long-data connection between the early warning part of the vehicle and the background server.
Step S200, controlling the early warning component in the low power consumption monitoring mode to transmit component status data obtained by executing the status monitoring function to the background server.
Specifically, each early warning component keeps monitoring the state of the early warning component in a low-power-consumption monitoring mode to acquire corresponding component state data, and then directly transmits the component state data to the background server through data connection established with the background server in the low-power-consumption monitoring mode, or transmits the component state data to the TBOX through the CAN bus, and then transmits the component state data to the background server through the TBOX in a unified manner. Therefore, the background server can always obtain the real-time component state data of the early warning component to perform safety early warning. The content of the safety early warning can comprise fault content definition, alarm level and the like, and then monitoring and early warning of vehicle risks and accidents are achieved.
In addition, in a preferred embodiment, in order to reduce energy consumption of the entire vehicle, in step S100, the early warning component of the vehicle is controlled to enter the preset low power consumption monitoring mode, and meanwhile, the non-early warning component of the vehicle is also controlled to enter the sleep mode. Wherein the sleep mode is configured such that all functions of the component are in a sleep state in which the component consumes minimal energy.
Therefore, in the power mode OFF state of the vehicle, the embodiment of the invention ensures that the early warning part does not sleep (namely, the data can be always kept to be uploaded), and other non-early warning modules sleep normally, thereby ensuring the transmission of the key early warning related information and reducing the energy consumption in the OFF state. In addition, in the prior art, before the whole vehicle does not enter a sleep state in an OFF mode, the TBOX acquisition and uploading data content is the same as the acquisition content in an ON mode, so that part of data has no value for vehicle safety early warning monitoring.
Example two
Fig. 2 is a flowchart illustrating a data transmission method for a vehicle according to a second embodiment of the present invention. On the basis of the method steps of the first embodiment corresponding to fig. 1, the second embodiment further includes the following steps:
and S310, receiving and executing a control instruction fed back by the background server in response to the component state data so as to realize vehicle control corresponding to the control instruction.
Specifically, the background server can perform a series of data processing such as judgment, analysis and control instruction generation according to the received component state data, and then generate a control instruction according with the current state of the vehicle to control the safe operation of the vehicle.
This is specifically described below by way of example. According to the research report on the safety of the power battery in 2019, the fire accidents of domestic new energy vehicles in recent two years are all caused by batteries: 41% of the vehicles are in a running state, 40% are in a standing state, and 19% are in a charging state.
Accordingly, in an example of the vehicle battery, when the warning component includes a storage battery, and the component state data corresponding to the storage battery includes a battery voltage, the step S310 may specifically include:
step S311, controlling the TBOX to receive a charging instruction fed back by the background server in response to the determination that the battery voltage is lower than the set voltage threshold, and performing charging on the storage battery.
Specifically, when the voltage of the battery (for example, a 12V battery) is lower than the set voltage threshold, there is a risk of a power shortage, which leads to problems such as the vehicle being unable to start and unable to switch to a high voltage. On the other hand, when the background server determines that the battery voltage is lower than the set voltage threshold, the background server transmits a charging command to the TBOX based on the voltage value determination result. After receiving the charging instruction, the TBOX can wake up the whole Vehicle, and after detecting that the Vehicle condition meets the preset conditions (for example, the power mode is OFF, four doors are locked, the whole Vehicle has no fault, a charging gun is not connected, etc.), the TBOX performs instruction signal routing through the gateway, and the VCU (Vehicle Control Unit) executes high-voltage action on the Vehicle.
Accordingly, in another example of the vehicle battery, when the warning component includes a storage battery, and the component state data corresponding to the storage battery includes a battery level, the step S310 may specifically include:
step S312, controlling the TBOX to receive a sleep instruction fed back by the background server in response to the determination that the battery power is lower than the set power threshold, and executing the sleep instruction to enable the relevant early warning component to enter a sleep mode.
Specifically, considering that the electric quantity of the vehicle needs to be in a healthy state, when the background server monitors that the electric quantity of a power battery of the whole vehicle is lower than a set electric quantity threshold (for example, 5%), a sleep instruction is sent to the TBOX, the TBOX routes an instruction signal to the ECU related to the three-electric system through the gateway, data uploading of the TBOX and the three-electric system is stopped, the TBOX is controlled to enter a sleep state, and the whole vehicle enters a low-power-consumption state of deep sleep.
In view of the above, be connected through early warning part and backend server's data length for battery voltage information and battery power information can transmit to backend server in real time, so that the backstage carries out early warning analysis and obtains suitable control command, has realized that battery insufficient voltage monitors and intelligent charging, has guaranteed vehicle performance.
It should be noted that the control manner of other warning components except for the storage battery is similar to that (for example, the monitoring of the specific state information of the three-electric system is realized), and therefore, the detailed description is omitted.
EXAMPLE III
Fig. 3 is a flowchart illustrating a data transmission method for a vehicle according to a third embodiment of the present invention. On the basis of the method steps of the first embodiment corresponding to fig. 1, the third embodiment further includes the following steps:
in step S320, the TBOX of the vehicle is controlled to execute vehicle control based on the component state data.
In contrast to the second embodiment, in the third embodiment, the TBOX implements a component function of the backend server, and for example, performs a series of data processing such as determination, analysis, and control command generation based on the received component status data.
In an example that the vehicle battery is also used, when the warning component includes a storage battery, and the component state data corresponding to the storage battery includes a battery voltage, the step S320 may specifically include:
step S321, determining whether the battery voltage is lower than a set voltage threshold by the TBOX, and if so, charging the storage battery.
In step S321, unlike the second embodiment, the TBOX locally implements monitoring of the battery voltage, specifically: and TBOX judges whether the voltage of the storage battery is lower than a set voltage threshold value, if so, the whole vehicle is awakened, and the same steps as those of the second embodiment after the whole vehicle is awakened are executed.
Similarly to the second embodiment, in another example of the vehicle battery, when the component state data corresponding to the storage battery includes a battery charge, the step S320 may specifically include:
step S322, judging whether the battery power is lower than a set power threshold value through the TBOX, and if so, controlling a related early warning component to enter a sleep mode.
In step S322, the TBOX locally implements battery level monitoring and directly sends a sleep command to the gateway, and the gateway routes a command signal to the three-electrical-system-related ECUs and the like, suspends data uploading thereof, and controls them to enter a sleep state, unlike the second embodiment.
The third embodiment of the invention has the effect which can be obtained by the second embodiment, but compared with the second embodiment of the invention, the third embodiment of the invention utilizes TBOX to reduce information interaction between related components and the background server, so that part of vehicle early warning and control functions can be completed locally, and the influence on vehicle control when the vehicle and the background server have data connection fault is avoided. It should be noted that, in order to ensure that the backend server can monitor the status of the early warning component in real time, the early warning component in the third embodiment of the present invention should be in the low power consumption monitoring mode and keep long data connection with the TBOX when the vehicle power mode is OFF, and the TBOX should be in the low power consumption monitoring mode and keep long data connection with the backend server when the vehicle power mode is OFF.
Example four
Fig. 4 is a schematic structural diagram of a data transmission system of a vehicle according to a fourth embodiment of the present invention, which has the same inventive concept as the first to third embodiments. Referring to fig. 4, the data transmission system of the vehicle may include: the control module 410 is configured to control an early warning component of a vehicle to enter a preset low power consumption monitoring mode when a vehicle power mode is an off mode, where the early warning component is a component that needs early warning monitoring by a background server of the vehicle, and the low power consumption monitoring mode is configured to enable the component to only retain a state monitoring function and a data transmission function corresponding to the background server; and a transmission module 420, configured to control the early warning component in the low power consumption monitoring mode to transmit component status data obtained by executing the status monitoring function to the background server.
