Thus, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure.
According to the research, when the electric automobile is not in use, the automobile can enter a dormant state, the controller in the automobile can enter a low-power-consumption state, and only a simple monitoring function is reserved. At this time, if the user uses the smart device such as the mobile phone to remotely control the vehicle, for example, remotely unlock and open the air conditioner, the user needs to send the control instruction to the cloud end, and then the cloud end issues the instruction to the vehicle, so as to complete the dormancy wakeup and the function execution of the vehicle.
However, when the vehicle is in a dormant state, the remote end issues the instruction to the vehicle, the vehicle needs to be instructed to establish a transmission control protocol (Transmission Control Protocol, TCP) connection with the cloud end, the instruction can be issued to the vehicle after the connection is established, the process takes a long time, and quick response to the user instruction can not be realized.
In the related art, in order to quickly respond to a user command, even if a vehicle is in a dormant state, a communication module on the vehicle is kept in a normal working mode all the time so as to maintain long connection between the vehicle and a gateway server to be effective, however, the communication module consumes a large amount of electric quantity in the mode, and the endurance mileage of the vehicle is affected.

For the convenience of understanding the present embodiment, first, a vehicle communication method disclosed in the embodiment of the present disclosure is described in detail, and an execution subject of the vehicle communication method provided in the embodiment of the present disclosure is a target vehicle, where the target vehicle may communicate with a cloud server.
Referring to fig. 1, a flowchart of a vehicle communication method according to an embodiment of the disclosure is shown, where the method includes steps 101 to 103, where:
And step 101, in a first power mode, responding to a first time interval for sending a heartbeat packet, and controlling the working mode of the communication module of the target vehicle to be switched from a low-power consumption mode to a target mode.
Step 102, sending a heartbeat packet to a gateway server through the communication module.
Step 103, determining that long connection between the target vehicle and the gateway server is effective when a heartbeat response sent by the gateway server is received in a second time interval after the communication module sends a heartbeat packet to the gateway server, and controlling the communication module to switch from the target mode to the low power consumption mode.
The following is a detailed description of the above steps.
For step 101 and step 102,
Here, the target vehicle is a vehicle in a first power mode, the first power mode may be a low power mode, and after the target vehicle enters the first power mode, the operation mode of each vehicle module of the target vehicle is switched to the low power mode, and by way of example, the first power mode may be a sleep mode, and after the target vehicle is flameout, the target vehicle may enter the first power mode.
The communication module of the target vehicle may refer to a software module responsible for communication between the target vehicle and a cloud server, and may exemplarily refer to a vehicle-to-vehicle (V2T) module.
In the low power mode, each vehicle module may operate with low power consumption, which may be, for example, an output current less than a preset current and/or an operating voltage less than a preset voltage. The target module may refer to a mode supporting the communication between the target vehicle and the gateway server, for example, the target module may refer to a normal operation mode, in which the operation state of each vehicle module is the same as the operation state of each vehicle module when the vehicle is running, and the power consumption of the vehicle module in the target mode is higher than that in the low power consumption mode.
In a possible implementation manner, the first time interval for sending the heartbeat packet may be a first time interval from the time of last receiving the heartbeat response, or a first time interval from the time of last receiving the service data response.
It should be noted that, after the first time interval for sending the heartbeat packet is reached, only the operation mode of the communication module of the target vehicle is switched from the low power consumption mode to the target mode, the operation modes of other modules on the target vehicle are still in the low power consumption mode, and the target vehicle is still in the first power supply mode.
In particular implementations, the target vehicle may establish a long connection with the gateway server prior to entering the first power mode, and may illustratively establish a message queue telemetry transport (Message Queuing Telemetry Transport, MQTT) long connection. Specifically, a transmission control protocol (Transmission Control Protocol, TCP) connection may be established through a three-way handshake, and then an MQTT long connection may be established. Further, after the target vehicle enters the first power mode, the validity of the long connection between the target vehicle and the gateway server can be maintained by sending a heartbeat packet to the gateway server.
Because the communication module cannot communicate with the gateway server in the low power consumption mode, the communication module can communicate with the gateway server through the heartbeat packet after being switched to the target mode.
Here, when sending the heartbeat packet to the gateway server, the communication module may send the heartbeat packet to the gateway server through the MQTT long connection. The heartbeat packet sent may be, for example, a Ping request (PINGREQ) packet or may be a tap packet.
Aiming at step 103,
In a second time interval of sending the heartbeat packet to the gateway server through the communication module, if the heartbeat response sent by the gateway server is received, the gateway server can normally receive the heartbeat packet, and the gateway service and the target vehicle can normally communicate with each other, so that the long connection is effective, the communication module can switch back to the low-power consumption mode in the current heartbeat period, and can switch back to the target mode again after waiting for the next first time interval of sending the heartbeat packet.
Optionally, after receiving the heartbeat response sent by the gateway server, the communication module may be directly controlled to switch from the target mode to the low power consumption mode, or after reaching the second time interval, the communication module may be controlled to switch from the target mode to the low power consumption mode.
For example, if the second time interval is 10 seconds after the heartbeat packet is sent by the communication module, if the heartbeat response is received at the 5 th second after the heartbeat packet is sent by the communication module, the communication module may be directly controlled to switch from the target mode to the low power consumption mode, or may be controlled to switch from the target mode to the low power consumption mode after the 10 th second after the heartbeat packet is sent by the communication module.
In an alternative embodiment, if the heartbeat response sent by the gateway server is not received within the second time interval of sending the heartbeat packet through the communication module, it is indicated that the communication between the target vehicle and the gateway server is faulty, so that it may be directly determined that the long connection between the target vehicle and the gateway server is invalid, and the long connection between the target vehicle and the gateway server is re-established.
In another possible implementation manner, after the target vehicle sends the heartbeat packet, the gateway service may normally receive the heartbeat packet, but because the gateway server fails/the gateway server needs to process more data, the gateway server cannot timely feed back the heartbeat response, so that in a third time interval after the heartbeat packet is sent through the communication module, if the heartbeat response sent by the gateway server is not received, it may be determined that the long connection between the target vehicle and the gateway server is invalid, and the long connection between the target vehicle and the gateway server is re-established, where the third time interval is greater than or equal to the second time interval.
After reestablishing the long connection between the target vehicle and the gateway server, the communication module may be controlled to switch from the target mode back to the low power mode.
Here, reestablishing the long connection between the target vehicle and the gateway server may specifically include establishing a TCP connection between the target vehicle and the gateway server and then establishing an MQTT connection between the target vehicle and the gateway server.
When the third time interval is greater than the second time interval and the heartbeat packet is sent to the gateway server through the communication module and exceeds the second time interval and does not exceed the third time interval, if a heartbeat response sent by the gateway server is received, long connection between the target vehicle and the gateway server can still be determined to be effective, and the communication module can be directly controlled to switch from the target mode to the low power consumption mode.
When the long connection between the target vehicle and the gateway server is determined to be invalid and the long connection between the target vehicle and the gateway server is re-established, if the long connection between the target vehicle and the gateway server fails to be established through multiple attempts, the current network state of the target vehicle is indicated that the long connection cannot be established, and the communication module is in the target mode for a long time at this time, so that the cruising of the target vehicle is possibly influenced.
Therefore, in one possible implementation manner, after determining that the long connection between the target vehicle and the gateway server is invalid when the heartbeat response sent by the gateway server is not received, the process of reestablishing the long connection between the target vehicle and the gateway server may be performed for a preset number of times, and in a case that the number of times of reestablishing the long connection between the target vehicle and the gateway server reaches the preset number of times, whether the long connection between the target vehicle and the gateway server is successfully established or not, the communication module may be controlled to switch from the target mode to the low power consumption mode, so as to reduce the influence on the cruising of the target vehicle.
Or under the condition that the heartbeat response sent by the gateway server is not received, after the long connection between the target vehicle and the gateway server is determined to be invalid, the long connection between the target vehicle and the gateway server can be re-established for multiple times, and if the duration of the communication module in the target mode after the long connection between the target vehicle and the gateway server is determined to be invalid reaches the preset duration, the communication module can be controlled to be switched from the target mode to the low-power consumption mode so as to reduce the influence on the continuous voyage of the target vehicle.
Alternatively, if the current network state of the target vehicle is poor, the long connection between the target vehicle and the gateway server cannot be supported, and therefore, when the long connection between the target vehicle and the gateway server is reestablished, the current network state of the target vehicle may be determined first, and when the network state meets the first preset condition, the long connection between the target vehicle and the gateway server is reestablished.
Here, the network state may be illustratively characterized by a signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP) and/or a signal to noise ratio (Signal to Interference plus Noise Ratio, SINR). The network state meeting the first preset condition may mean that RSRP is greater than a first preset value or SINR is greater than a second preset value.
Since the purpose of maintaining a long connection between the target vehicle and the gateway server is to respond to the user command quickly, the user may not send the user command to the target vehicle for some time intervals, such as 2:00-5:00 a.m., so that even if the target vehicle is intermittently connected to the gateway server during the time interval, no influence is exerted on the user.
In another possible implementation manner, when the long connection between the target vehicle and the gateway server is reestablished, the instruction requirement information corresponding to the target vehicle at present can be determined first, wherein the instruction requirement information is used for representing the probability that a user sends an instruction to the target vehicle, and when the instruction requirement information meets a second preset condition, the long connection between the target vehicle and the gateway server is reestablished.
Here, the instruction demand information may be exemplarily determined according to the reception situation of the history instruction. Based on the receiving condition of the historical instructions, the instruction demand information of each preset time interval can be determined, and then the long connection between the target vehicle and the gateway server is reestablished under the condition that the instruction demand information exceeds the preset probability (namely, the second preset condition is met).
Accordingly, in one possible implementation manner, after the first time interval for sending the heartbeat packet is reached, before the operation mode of the communication module of the target vehicle is controlled to switch, the current network state of the target vehicle may be detected first, and/or the demand information may be instructed, and if the network state meets the first preset condition, and/or the demand information may be instructed to meet the second preset condition, the switching of the operation mode of the communication module of the target vehicle may be controlled to maintain the long connection between the target vehicle and the gateway server.
Alternatively, if the gateway server does not receive the heartbeat packet sent by the target vehicle for a long time, the gateway server may also send the heartbeat packet back to the target vehicle to maintain between the gateway server and the target vehicle.
Specifically, the target vehicle may receive a heartbeat packet sent by the gateway server, where the heartbeat packet may be sent by the gateway server if the heartbeat packet sent by the target vehicle is not received after the fourth time interval is reached, and then the target vehicle may determine that the long connection between the target vehicle and the gateway server is valid and send a heartbeat response to the gateway server.
Here, if the communication module of the target vehicle is in the low power consumption mode after the target vehicle receives the heartbeat packet sent by the gateway server, the communication module may be switched to the target mode first, and the heartbeat response may be sent to the gateway server in the target mode.
If the gateway server does not receive the heartbeat response sent by the target vehicle, the gateway server indicates that the uplink between the target vehicle and the gateway server fails, the gateway server can disconnect the connection between the target vehicle and the gateway server, and when the target vehicle sends the heartbeat packet after reaching the sending interval of the next heartbeat packet, if the target vehicle detects that the heartbeat packet is failed to be sent, the long connection between the target vehicle and the gateway server can be directly re-established.
Optionally, if a control instruction sent by the gateway server is received, the target vehicle may be controlled to switch from the first power mode to a second power mode, and respond to the control instruction in the second power mode, where a working mode of each vehicle module in the second power mode is a normal working mode. The control instruction may be sent from the user side to the gateway server.
Because the long connection between the target vehicle and the gateway server is always maintained, the target vehicle can directly receive the control command sent by the gateway server and respond to the control command without reestablishing the TCP connection, thereby realizing quick response to the control command.
The foregoing vehicle communication method will be described with reference to the specific embodiments, and an example diagram of the vehicle communication method provided by the embodiment of the disclosure is shown in fig. 2, and is mainly used for describing a communication process between a vehicle end (i.e., a target vehicle) and a cloud end (i.e., a gateway server), where the cloud end can store an online state of MQTT long connection (i.e., validity of MQTT long connection), and when the vehicle is in a second power mode, the vehicle end can send a service data packet to the cloud end, and the cloud end sends a service response to the vehicle end, so that the online state of MQTT long connection of the cloud end can be refreshed.
After the vehicle is flameout, the vehicle end enters a first power supply mode, each module of the vehicle end sleeps, the State of Charge (SOC) of the battery enters a low power consumption mode, after a first time interval (110 seconds) for sending the heartbeat packet is reached, the communication module of the vehicle end wakes up (namely, switches to a target mode) and sends the heartbeat packet to the cloud, after receiving the heartbeat response, the communication module sleeps, and after the next 110 seconds, the communication module sends the heartbeat packet to the cloud again.
If the heartbeat response is not received in the second time interval (10 seconds after the heartbeat packet is sent), waiting for 5 seconds (the third time interval is 5+10 seconds), if the heartbeat response can be received in 5 seconds, still confirming the MQTT long connection, and if the heartbeat response is not received, triggering the MQTT reconnection.
The cloud end does not receive the heartbeat packet within a fourth time interval (namely +110 seconds +10 seconds +15 seconds after the last heartbeat packet is received), the heartbeat packet can be actively sent to the vehicle end, the vehicle end can send a heartbeat response to the cloud end after receiving the heartbeat packet, if the cloud end does not receive the heartbeat response within 5 seconds after sending the heartbeat packet, the MQTT connection can be actively disconnected, and the vehicle end can trigger the MQTT reconnection after detecting the MQTT connection disconnection.
After the MQTT reconnection is successful, the communication module may be awakened again at certain intervals, as per the example above, to maintain the MQTT long connection active.
It should be noted that, in the above examples, the number of seconds is an example, and may be set according to actual requirements in practical applications.
In the vehicle communication method provided by the embodiment of the disclosure, when the target vehicle is in the first power mode, the working mode of the communication module of the target vehicle can be controlled to be switched from the low-power mode to the target mode according to the first time interval for sending the heartbeat packet, the heartbeat packet is sent to the gateway server through the communication module so as to maintain the validity of long connection between the target vehicle and the gateway server, and after the heartbeat response sent by the gateway server is received, the communication module is controlled to be switched back to the low-power mode through the target mode, so that the long connection validity of the target vehicle and the gateway server can be maintained for a long time without affecting the endurance mileage of the target vehicle, and when a user sends an instruction to the target vehicle remotely, the instruction can be quickly sent to the target vehicle through the long connection, and the user instruction can be conveniently responded quickly.
