[0023] In order to enable those skilled in the art to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] The vehicle drainage control method provided by the embodiments of the present application can be implemented by a computer device, which can be a terminal device or a server. The server can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device includes but is not limited to a mobile phone, a computer, a smart voice interactive device, a smart home appliance, a vehicle-mounted terminal, etc. The terminal device and the server can be connected directly or indirectly through wired or wireless communication, which is not limited in the present application.

[0025] The embodiments are specifically described as follows:

[0026] Figure 1 A flowchart of a vehicle drainage control method provided by an embodiment of the present application is shown in the figure, which is described by taking a server as the aforementioned computer device. The method comprises S101-S103.

[0027] S101: receiving a remote drainage instruction sent by a user when there is no one inside a vehicle.

[0028] S102: in response to the remote drainage instruction, sending the remote drainage instruction to a target vehicle according to a vehicle identifier of the target vehicle.

[0029] For a hydrogen energy vehicle, the electric pile system will generate liquid water during driving. If the user forgets to actively drain water in the vehicle in time, the user has to enter the vehicle again to control the vehicle drainage, which brings great inconvenience to the user. To this end, the remote drainage control mechanism provided by the present application can be used. In specific implementation, a remote drainage instruction sent by a user when there is no one inside a vehicle can be received first. The remote drainage instruction comprises a vehicle identifier of a target vehicle, which is used to uniquely identify the target vehicle. The target vehicle can be the vehicle of the user, i.e., the user can be the owner of the target vehicle.

[0030] Further, the remote drainage instruction can be sent to the target vehicle according to the vehicle identifier in response to the remote drainage instruction, so as to control the drainage process and the like subsequently.

[0031] In a possible implementation, the user can initiate the remote drainage instruction through a remote application running on a terminal device, such as a smart phone, a smart tablet or the like. Specifically, the user can perform a click operation on the remote application, and then the remote application sends the remote drainage instruction to the vehicle remote service platform in response to the click operation of the user on the remote application. The remote application and the vehicle remote service platform are in a communication connection relationship.

[0032] It can be understood that, in order to remotely control the target vehicle to drain, the target vehicle needs to be connected to the vehicle remote service platform, and therefore, the login state of the target vehicle on the vehicle remote service platform can be verified through the vehicle remote service platform according to the vehicle identifier in response to the remote drainage instruction. If the login state of the target vehicle is logged in, it indicates that the target vehicle has been connected to the vehicle remote service platform, and therefore, the remote drainage instruction can be directly sent to the vehicle remote terminal of the target vehicle through the vehicle remote service platform.

[0033] In actual application, if the login state of the target vehicle is not logged in, the vehicle remote service platform can first call a short message interface to send a wake-up short message to the vehicle remote terminal of the target vehicle according to the vehicle identifier, the wake-up short message including the vehicle identifier and a wake-up timestamp, for waking up the target vehicle and facilitating the target vehicle to be connected to the vehicle remote service platform. When the vehicle remote terminal receives the wake-up short message, the vehicle remote terminal can verify the vehicle identifier and the wake-up timestamp to obtain a wake-up verification result. If the wake-up verification result is passed, it indicates that the vehicle identifier in the wake-up short message is the vehicle identifier of the target vehicle, and the wake-up timestamp matches the timestamp of the target vehicle, and therefore, the vehicle remote terminal can send a login request to the vehicle remote service platform. After the vehicle remote service platform receives the login request, the vehicle remote service platform can switch the login state of the target vehicle from not logged in to logged in in response to the login request. Based on this, in the case that the target vehicle is not connected to the vehicle remote service platform, the wake-up short message is used to establish the connection, so as to remotely control the drainage of the target vehicle subsequently.

[0034] It can be understood that, if the wake-up short message verification fails, it indicates that the wake-up short message received by the target vehicle may have a problem such as illegal wake-up, and therefore, the vehicle remote terminal can send a wake-up failure instruction to the vehicle remote service platform, and then the vehicle remote service platform returns prompt information that the target vehicle is not online to the remote application, so that the user can learn the status of the target vehicle in time.

[0035] wherein the remote application can refer to Figure 2 the APP (Application) shown in FIG. 1, the vehicle remote service platform can refer to Figure 2 the TSP (Telematics Service Provider) shown in FIG. 1, and the vehicle remote terminal can refer to Figure 2 the TBOX (Telematics-BOX) shown in FIG. 1. In actual applications, data transmission can be performed between the APP and the TSP and between the TBOX and the TSP through https requests. Specifically, the communication connection relationship between the APP and the TSP can be established based on a SOCKET connection. Based on this, the APP can send a remote drainage instruction to the TSP in a JSON data format. Similarly, after the wake-up short message verification, the TBOX can send a login request or a wake-up failure instruction to the TSP in a JSON data format. Correspondingly, after receiving the wake-up failure instruction, the TSP can return prompt information that the target vehicle is not online to the APP in a JSON data format.

[0036] S103: Controlling the target vehicle to drain according to the remote drainage instruction.

[0037] After the remote drainage instruction is sent to the target vehicle, the target vehicle can be controlled to drain according to the remote drainage instruction. Based on this, the remote drainage instruction is used to realize the drainage control of the target vehicle in the case that no one is in the vehicle, thereby bringing convenience to the user.

[0038] In a possible implementation, after the target vehicle receives the remote drainage instruction, the vehicle condition of the target vehicle can be first acquired through the vehicle remote terminal of the target vehicle, and the vehicle condition is used to reflect the current condition state of the target vehicle. If the vehicle condition meets the condition that no one is in the vehicle, the vehicle remote terminal can be used to control the target vehicle to drain according to the remote drainage instruction. In actual applications, the vehicle condition can include a vehicle speed condition and a gear condition. In specific implementation, if the vehicle speed condition is zero and the gear condition is P gear, it can be considered that the vehicle condition meets the condition that no one is in the vehicle, and the target vehicle can be controlled to drain at this time. Based on this, the current condition state of the target vehicle is further judged, and the remote drainage control process is optimized.

[0039] In practical applications, the remote drainage instruction can be sent to the TBOX through a https request by the TSP, and then the TBOX obtains the vehicle speed condition veicle_speed and the gear level condition geal_level. When veicle_speed = 0 and geal_level = P, it can be considered that the target vehicle meets the condition of no one in the vehicle, and remote control drainage can be performed. Correspondingly, if the TBOX judges that the vehicle condition does not meet the condition of no one in the vehicle, a prompt message that the vehicle condition does not meet the condition can be returned to the TSP, so that the execution fails. Correspondingly, the TSP returns a prompt message of “execution failed, please retry” to the APP, so that the user can understand the remote drainage control situation in time through the APP.

[0040] In order to more accurately remotely control drainage, after the vehicle-mounted remote terminal receives the remote drainage instruction, the vehicle-mounted remote terminal can first convert the remote drainage instruction to obtain a remote drainage signal. The remote drainage signal is a CAN signal, which conforms to the CAN signal protocol of the target vehicle, so as to facilitate the vehicle-mounted remote terminal to control the target vehicle to drain. In specific implementation, the vehicle-mounted remote terminal sends the remote drainage signal to the body domain controller of the target vehicle and the drainage controller of the target vehicle. In response to the remote drainage signal, the body domain controller can detect the external environment temperature of the target vehicle, and the drainage controller starts timing for a first preset time length when receiving the remote drainage signal. Correspondingly, if the drainage controller receives the start heating signal sent by the body domain controller within the first preset time length, it indicates that the external environment temperature of the target vehicle is currently low, which is not suitable for direct drainage. In order to realize drainage, the drainage controller can heat the drainage pipeline of the target vehicle according to the start heating signal, and then control the target vehicle to drain according to the remote drainage signal. The start heating signal is generated by the body domain controller according to the external environment temperature. On the contrary, if the drainage controller does not receive the start heating signal sent by the body domain controller within the first preset time length, it indicates that the external environment temperature of the target vehicle can be directly drained. At this time, the drainage controller can control the target vehicle to drain according to the remote drainage signal.

[0041] In practical applications, when the external environment temperature is below zero Celsius, it can be considered that heating is needed before drainage. At this time, it can be determined that the start heating signal is generated and sent to the drainage controller. When the external environment temperature is above zero Celsius, it can be considered that direct drainage can be performed. At this time, it can be determined that the start heating signal is not sent.

[0042] It should be noted that the first preset time length can be set according to the parameters of the target vehicle body domain controller, and the present application does not make any limitation. For example, considering the time required for the body domain controller to detect the external environment temperature and the time required for sending the start heating signal to the drainage controller, etc., the first preset time length can be set to 5 seconds.

[0043] The body domain controller can refer to the central controller (Central Control Unit, CCU) shown in Figure 2 The drainage controller can refer to the drainage controller (Water Control Unit, WCU) shown in Figure 2 In actual application, the TBOX can convert the remote drainage instruction into a remote drainage signal, which can be a CAN signal remote_push_water. In response to remote_push_water, the CCU can use a temperature sensor to detect the external environment temperature based on the hard line of the target vehicle, and then when the external environment temperature is below 0°C, it is confirmed to generate a start heating signal, which is a CAN signal start_heat, and send start_heat to WCU. When the external environment temperature is above 0°C, the CCU can not perform any action, so that the WCU will not receive start_heat within the first preset time length, and directly perform drainage. That is, the WCU receives remote_push_water at the same time, and waits for 5 seconds whether start_heat is received. Based on this, the drainage control can be optimized according to the external environment temperature where the target vehicle is located.

[0044] In order to enable the user to know the remote control drainage condition in time, in a possible implementation, after sending the remote drainage signal to the vehicle body domain controller and the drainage controller through the vehicle-mounted remote terminal, the vehicle-mounted remote terminal can start timing for a second preset time length. In specific implementation, if the vehicle-mounted remote terminal receives the start drainage feedback signal sent by the drainage controller within the second preset time length, and then sends the execution success instruction to the vehicle remote service platform through the vehicle-mounted remote terminal, the start drainage feedback signal is generated by the drainage controller after controlling the target vehicle to drain according to the remote drainage signal, and is used to indicate the state that the drainage control has been started, which can be a CAN signal start success. Then, in response to the execution success instruction, the vehicle remote service platform can send the state prompt information that the drainage has been started successfully to the remote application. If the vehicle-mounted remote terminal does not receive the start drainage feedback signal within the second preset time length, it is considered that the target vehicle cannot be controlled to start drainage within the second preset time length, at this time, the vehicle-mounted remote terminal can send the timeout non-execution instruction to the vehicle remote service platform, and then the vehicle remote service platform sends the state prompt information that the drainage has failed to start to the remote application in response to the timeout non-execution instruction. Based on this, the user can receive the state prompt message of whether the drainage has been started successfully in time after initiating the remote drainage instruction, thereby improving the user experience.

[0045] It should be noted that the second preset time length can be set according to actual conditions, and the present application does not make any limitation. For example, according to the signal transmission time and other parameters calibrated by the vehicle engineer in the laboratory, the second preset time length is set to 30 seconds.

[0046] In a possible implementation, a state monitoring mechanism can also be added, so that the user can know the drainage pipeline state in time and can be repaired in time once an abnormality occurs. In specific implementation, the drainage controller can be used to monitor the state of the drainage pipeline, and if the state of the drainage pipeline is abnormal, the drainage controller can send an alarm signal to the vehicle-mounted remote terminal. Then, in response to the alarm signal, the vehicle-mounted remote terminal sends the remote alarm instruction to the vehicle remote service platform, and the vehicle remote service platform sends the alarm information to the remote application in response to the remote alarm instruction. Based on this, the user can know the drainage pipeline condition in time through the remote application, and can repair it in time once an abnormality occurs.

[0047] In actual application, the WCU can monitor the state of the drainage pipeline through the hard line of the target vehicle, for example, when monitoring that the state of the drainage pipeline is abnormal, an alarm signal can be sent, which can be a CAN signal water ErrorSts = warning.

[0048] It can be seen from the technical scheme that when there is no one in the vehicle, the user can control the vehicle to drain water through a remote drainage instruction. Specifically, the remote drainage instruction sent by the user when there is no one in the vehicle is received, the remote drainage instruction includes the vehicle identification of the target vehicle, and then the remote drainage instruction is sent to the target vehicle according to the vehicle identification in response to the remote drainage instruction. Finally, the target vehicle can be controlled to drain water according to the remote drainage instruction. Based on this, a remote control drainage mechanism when there is no one in the vehicle is provided, so that the vehicle can be controlled to complete drainage even if the user forgets to control the vehicle to drain water in the vehicle, without the need to enter the vehicle again, which brings convenience to the user, and damage to vehicle parts caused by forgetting to drain water can also be avoided.

[0049] In the above embodiments, a vehicle drainage control system is provided, which can be specifically seen from Figure 2 The vehicle drainage control system includes a remote application APP, a vehicle remote service platform TSP, a vehicle-mounted remote terminal TBOX, a body domain controller CCU, a temperature sensor, a drainage controller WCU, and an actuator. Correspondingly, the present application also provides a logic diagram of a vehicle drainage control method, which can be specifically seen from Figure 3 The vehicle drainage control system shown in Figure 2 The logic of the vehicle drainage control method shown in Figure 3

[0050] When there is no one in the vehicle and drainage is needed, the user can first initiate a remote drainage instruction through the APP. Specifically, the user can execute step 1 to establish a SOCKET connection with the TSP using the APP, and then send a remote drainage instruction to the TSP. After the TSP receives the remote drainage instruction, the TSP first executes step 2 to determine whether the TBOX of the target vehicle is logged in. When it is determined that the TBOX is logged in, step 3 is executed to send the remote drainage instruction to the TBOX. When it is determined that the TBOX is not logged in, step 2.1 is executed to call an interface to issue a wake-up short message. Then, the TBOX can be verified when receiving the wake-up short message. When the verification is passed, step 2.2 is executed to send a login request, so that the TSP switches the TBOX from not logged in to logged in. Correspondingly, when the verification fails, it indicates that the wake-up fails, and the TSP executes step 2.3 to return a wake-up failure prompt to the APP.

[0051] ​When the TBOX receives the remote drainage instruction, it can first perform step 3.2 to determine whether the vehicle condition meets the no-one-in-vehicle condition. Specifically, it can be determined by judging the vehicle speed condition veicle_speed and the gear condition geal_level. When veicle_speed = 0 and geal_level = P, the no-one-in-vehicle condition is met, and step 4 is performed to send a remote push water signal remote_push_water to the CCU and the WCU, and a timer is started (the timing duration is the second preset duration mentioned above). When the no-one-in-vehicle condition is not met, step 3.2.1 is performed to send a vehicle condition not met to the TSP, so that the TSP performs step 3.2.2 to feed back a prompt information of “execution failed, please retry” to the APP.

[0052] During the TBOX timing, after the CCU receives the remote_push_water signal, step 5 is performed to detect whether the external environment temperature is below 0°C based on the hard-wire temperature sensor. If it is below 0°C, step 5.1 is performed to send a start heating signal start_heat to the WCU. After the WCU receives the remote_push_water signal, step 5 is performed to determine whether the start_heat signal is received within 5 seconds (i.e. the first preset duration mentioned above). If the start_heat signal is received within 5 seconds, the WCU performs step 5.1 to heat the drainage pipeline and drain water, and sends a start_success signal to the TBOX. If the start_heat signal is not received within 5 seconds, the WCU performs step 5.2 to directly drain water, and sends a start_success signal to the TBOX. Correspondingly, after the TBOX receives the start_success signal, it can perform step 5.1.1 or 5.2.1 to send an execution success instruction to the TSP, so that the TSP performs step 5.1.2 or 5.2.2 to feed back a state prompt information of successful start of drainage to the APP.

[0053] If the TBOX does not receive the start_success signal outside the TBOX timing, the TBOX performs step 4.1 to send a timeout not executed instruction to the TSP, so that the TSP performs step 4.2 to feed back a state prompt information of failed start of drainage to the APP.

[0054] Meanwhile, the WCU can also monitor the state of the drainage pipeline in the whole process, and when an abnormal state of the drainage pipeline is monitored (including pipeline abnormality and operation abnormality), the WCU sends an alarm signal water_ErrorSts=warning to the TBOX. Then, after the TBOX receives the water_ErrorSts=warning, the TBOX sends a remote alarm instruction to the TSP, so that the TSP feeds back alarm information to the APP.

[0055] It can be understood that it basically corresponds to the method embodiment, so the related parts can be referred to the part of the method embodiment.

[0084] In response to the execution success instruction, the vehicle remote service platform sends state prompt information of successful opening of drainage to the remote application program.

[0085] If the vehicle-mounted remote terminal does not receive the start drainage feedback signal within the second preset time length, the vehicle-mounted remote terminal sends a timeout non-execution instruction to the vehicle remote service platform.
