Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a remote control method, device, storage medium, and vehicle for a hybrid vehicle. Background Technology

[0002] Currently, with the rapid development of intelligent vehicles, most vehicles are equipped with remote control functions. With this function, people can remotely start the vehicle, remotely start the air conditioning, and remotely clean the cabin, etc.

[0003] However, in related technologies, the aforementioned remote control functions cannot be implemented when a hybrid vehicle is plugged into a charging gun to charge its battery pack. Summary of the Invention

[0004] In view of this, the present invention aims to provide a remote control method, device, storage medium and vehicle for hybrid vehicles, so that the hybrid vehicle can at least realize some remote control functions regardless of whether the power battery pack is charged or not.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A remote control method for a hybrid vehicle, the remote control method comprising:

[0007] Upon receiving a remote control command for a vehicle, determine the charging status of the vehicle's power battery pack and the control type corresponding to the remote control command.

[0008] Based on the charging status and the control type, determine whether to execute the remote control command;

[0009] When executing the remote control command, the vehicle is controlled to perform the remote control function corresponding to the remote control command.

[0010] Furthermore, determining whether to execute the remote control command based on the charging state and the control type includes:

[0011] When the charging status is determined to be that the vehicle is not plugged into the charging gun, the remote control command is executed;

[0012] When it is determined that the charging state is that the vehicle is plugged into the charging gun, and when it is determined that the control type corresponding to the remote control command is the first type, the execution of the remote control command is prohibited.

[0013] When it is determined that the charging state is that the vehicle is plugged into the charging gun, and when it is determined that the control type corresponding to the remote control command is the second type, the remote control command is executed.

[0014] The first type of remote control refers to the control of the vehicle to enter the corresponding driving condition, and the second type of remote control command is used to control the on-board components of the vehicle to enter the corresponding working state.

[0015] Furthermore, when the control type corresponding to the remote control command is the second type, executing the remote control command when it is determined that the charging state is that the vehicle is not plugged into the charging gun includes:

[0016] Obtain the SOC of the power battery pack and the component to be controlled corresponding to the remote control command;

[0017] Based on the SOC, the starting power supply node when the controlled component enters the working state is determined; wherein, the starting power supply node is used to supply power to the controlled component;

[0018] The connection between the starting power supply node and the component to be controlled is established so that the component to be controlled enters the working state.

[0019] Furthermore, determining the starting power supply node when the controlled component enters the working state based on the SOC includes:

[0020] When the SOC is not lower than the preset SOC, the starting power supply node is determined to be the power battery pack;

[0021] When the SOC is lower than the preset SOC, the starting power supply node is determined to be the vehicle's engine.

[0022] Furthermore, the first type of remote control commands includes: commands to remotely start the vehicle and commands to remotely park the vehicle;

[0023] The second type of remote control commands includes at least one of the following: commands to remotely start the air conditioning, commands to remotely clean the cabin, commands to remotely turn on the seat heating and ventilation, and commands to remotely turn on the steering wheel heating.

[0024] Furthermore, when it is determined that the charging state is that the vehicle is plugged into the charging gun, and when it is determined that the control type corresponding to the remote control command is the first type, the remote control method further includes:

[0025] Send a first prompt message to the user to prompt the user to disconnect the charging gun;

[0026] If the charging gun is detected to be disconnected, the first type of remote control command is executed.

[0027] Furthermore, before determining whether to execute the remote control command based on the charging state and the control type, the remote control method further includes:

[0028] When the charging state is determined to be the state of the charging gun being inserted, a disable command is sent to the user terminal to instruct the user terminal to lock the triggering of the first type of remote control command;

[0029] When the charging state is determined to be the state where the charging gun is not inserted, an unlock command is sent to the user terminal to instruct the user terminal to change the triggering state of the first type of remote control command from the locked state to the unlocked state.

[0030] Compared with existing technologies, the remote control method for hybrid vehicles described in this invention has the following advantages:

[0031] This invention provides a remote control method for a hybrid vehicle, the method comprising: upon receiving a remote control command for the vehicle, determining the charging state of the vehicle's power battery pack and the control type corresponding to the remote control command; based on the charging state and the control type, determining whether to execute the remote control command; and when executing the remote control command, controlling the vehicle to perform a remote control function corresponding to the control type.

[0032] Therefore, upon receiving a remote control command, this invention first confirms the charging status of the power battery pack, i.e., whether the vehicle is plugged into a charging gun to charge the power battery pack, and simultaneously determines the control type corresponding to the remote control command, thereby determining whether the remote control command can be executed. This ensures that all remote control functions of the vehicle can be executed even when the vehicle is not plugged into a charging gun to charge the power battery pack. Furthermore, when executing the remote control function corresponding to the second type of remote control command, the power battery's charge can be used first; when the power battery charge is low, the engine is started to continue executing the remote control function. When the vehicle is plugged into a charging gun to charge the power battery pack, and the control type of the remote control command is determined to be the second type, only high voltage needs to be supplied to the vehicle; the engine does not need to be started to achieve the corresponding remote control function. Thus, regardless of whether the vehicle is plugged into a charging gun to charge the power battery pack, the user can remotely control the vehicle to execute remote control functions, greatly improving the user experience.

[0033] Another objective of this invention is to provide a remote control device for hybrid vehicles, enabling hybrid vehicles to perform at least some remote control functions regardless of whether the power battery pack is being charged or not.

[0034] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0035] A remote control device for a hybrid vehicle, the remote control device comprising:

[0036] The first determining unit is used to determine the charging status of the vehicle's power battery pack and the control type corresponding to the remote control command when it receives a remote control command for the vehicle.

[0037] The second determining unit is used to determine whether to execute the remote control command based on the charging state and the control type.

[0038] The control unit is used to control the vehicle to perform remote control functions corresponding to the control type when executing the remote control command.

[0039] The advantages of the remote control device and the aforementioned remote control method over the prior art are the same, and will not be elaborated here.

[0040] Another object of the present invention is to provide a computer-readable storage medium that enables hybrid vehicles to achieve at least some remote control functions regardless of whether the battery pack is being charged or not.

[0041] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0042] A computer-readable storage medium for storing a computer program that performs the remote control method described above.

[0043] The computer-readable storage medium has the same advantages as the aforementioned remote control method over the prior art, and will not be elaborated here.

[0044] Another object of the present invention is to provide a vehicle in which a hybrid vehicle can at least achieve some remote control functions regardless of whether the power battery pack is charged or not.

[0045] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0046] A vehicle includes a control module for implementing the remote control method described above.

[0047] The vehicle described above has the same advantages over existing technologies as the remote control method described above, and will not be elaborated here. Attached Figure Description

[0053] It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0054] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] In related technologies, when a hybrid vehicle is plugged into a charging gun, the vehicle is usually prohibited from starting in order to avoid safety accidents (this starting refers to the vehicle's ready-to-start state before the engine starts). At this time, the engine cannot start, and the vehicle's components, such as the air conditioner and seats, cannot be started, making it impossible for the vehicle to perform related remote control functions.

[0056] In view of this, embodiments of the present invention propose a remote control method for hybrid vehicles, enabling the aforementioned remote control functions to be achieved even when the hybrid vehicle is plugged into a charging gun. (Refer to...) Figure 1 , Figure 1 A flowchart illustrating the steps of a remote control method for a hybrid vehicle according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the steps of this remote control method are as follows:

[0057] Step S101: Upon receiving a remote control command for the vehicle, determine the charging status of the vehicle's power battery pack and the control type corresponding to the remote control command.

[0058] In practice, users can trigger the remote control function via an app. In response to this trigger, the app sends a corresponding remote control command to the vehicle. For example, after triggering the remote start function on the app, the app sends a command to start the vehicle. Specifically, the app sends the remote control command to the T-BOX (Telematics BOX, a vehicle-to-everything intelligent terminal). Upon receiving the command, the T-BOX first checks the charging status of the battery pack to determine whether the charging status is determined by whether the vehicle is plugged into the charging gun or not, i.e., whether the battery pack is charging or not. Simultaneously, the T-BOX also determines the control type corresponding to the remote control command.

[0059] The remote control commands correspond to two types of control types: one type controls the entire vehicle, such as remotely starting the vehicle and remotely parking the vehicle; the other type controls components on the vehicle, such as controlling the air conditioning, seats, steering wheel, etc. Specifically, this could be a command to remotely start the air conditioning, a command to remotely clean the cabin, a command to remotely turn on the seat heating and ventilation, and a command to remotely turn on the steering wheel heating, etc.

[0060] Step S102: Based on the charging state and the control type, determine whether to execute the remote control command.

[0061] After determining the charging status of the power battery pack and the control type corresponding to the remote control command, T-BOX determines whether to execute the received remote control command based on the determined charging status and control type. If execution is desired, an execution signal is sent to the gateway, which receives the execution signal and forwards it to the vehicle controller; if execution is not desired, feedback is sent to the APP, which then prompts the user that "remote control function is disabled".

[0062] Step S103: When executing the remote control command, control the vehicle to perform the remote control function corresponding to the remote control command.

[0063] After receiving the execution signal from the gateway, the vehicle controller controls the vehicle to perform the remote control function corresponding to the remote control command. For example, if the user triggers a remote control function via the app to remotely start the vehicle, the vehicle controller, upon receiving the execution signal, will send a start signal to the engine controller. The engine controller, in response to this start signal, will start the engine, thus achieving remote vehicle start. Alternatively, if the user triggers a remote control function via the app to remotely start the air conditioning, the vehicle controller, upon receiving the execution signal, will send a start signal to the air conditioning controller. The air conditioning controller, in response to this start signal, will start the air conditioning, thus achieving remote air conditioning start.

[0064] The vehicle controller, after controlling the vehicle to perform remote control functions, will also send a success signal to the gateway. The gateway receives the success signal and forwards it to the T-BOX. The T-BOX then forwards it to the APP. After receiving the signal, the APP will prompt the user that "remote control function has been successfully executed".

[0065] Furthermore, if the T-BOX does not receive a successful execution signal within the first preset time period, it will send the execution signal to the gateway again. The T-BOX will send the execution signal no more than three times. If the T-BOX still does not receive a successful execution signal after sending the third execution signal, it will send an execution failure signal to the APP. Upon receiving the feedback, the APP will prompt the user with "Remote control function execution failed." After receiving this prompt, the user can choose to trigger the remote control function again. The first preset time period is 5 seconds.

[0066] In practical implementation, to conserve vehicle energy, when a user triggers a remote control function corresponding to a command controlling a vehicle component, such as remotely starting the air conditioning, remotely cleaning the cabin, or remotely activating seat heating and ventilation, the T-BOX, upon receiving a successful execution signal, waits for a second preset duration before sending an end signal to the gateway. The gateway receives this end signal and forwards it to the vehicle controller. Upon receiving the end signal, the vehicle controller stops the corresponding remote control function. The second preset duration is actually the execution time of the remote control function; therefore, different remote control functions correspond to different execution times, i.e., the second preset duration. For example, if remote cabin cleaning is triggered, the corresponding second preset duration is 2 minutes, meaning the vehicle will perform cabin cleaning for 2 minutes.

[0067] When the vehicle stops performing remote control functions, the vehicle controller sends an end signal to the gateway. The gateway receives the end signal and forwards it to the T-BOX. The T-BOX receives the signal and forwards it to the APP. The APP then prompts the user that "remote control function has been completed".

[0068] In one optional implementation, determining whether to execute the remote control command based on the charging state and the control type includes:

[0069] When the charging status is determined to be that the vehicle is not plugged into the charging gun, the remote control command is executed;

[0070] When it is determined that the charging state is that the vehicle is plugged into the charging gun, and when it is determined that the control type corresponding to the remote control command is the first type, the execution of the remote control command is prohibited.

[0071] When it is determined that the charging state is that the vehicle is plugged into the charging gun, and when it is determined that the control type corresponding to the remote control command is the second type, the remote control command is executed.

[0072] The first type of remote control command is used to control the vehicle to enter the corresponding driving condition, which includes starting the vehicle, parking, etc. Therefore, the first type of remote control command can be a command to remotely start the vehicle, a command to remotely park, etc.

[0073] The second type of remote control command is used to control the vehicle's onboard components to enter the corresponding working state. For example, it can control the vehicle's air conditioning, seats, and steering wheel to enter the corresponding working state. Therefore, the second type of remote control command can be a command to remotely start the air conditioning, a command to remotely clean the cabin, a command to remotely turn on the seat heating and ventilation, and a command to remotely turn on the steering wheel heating, etc.

[0074] When the T-BOX determines that the charging status is that the vehicle is plugged into the charging gun, meaning the power battery pack is charging, and determines that the control type corresponding to the remote control command is Type 1, it will notify the APP that the remote control command is prohibited from execution. Upon receiving this feedback, the APP will prompt the user that "Remote control function is prohibited." This is because Type 1 remote control commands are commands that control the entire vehicle, such as commands to start the vehicle or park it. To avoid safety accidents, starting or parking the vehicle is prohibited when the charging gun is plugged in.

[0075] For example, when a user triggers the remote control function to start the vehicle in the APP, in response to the triggering of the remote control function, the APP sends the corresponding remote control command to the T-BOX, that is, the command to start the vehicle remotely. After receiving the command to start the vehicle remotely, the T-BOX determines that the charging status at this time is that the vehicle is plugged into the charging gun. After determining that the control type corresponding to the command to start the vehicle remotely is the first type, it sends a feedback to the APP that the command to start the vehicle remotely is prohibited from being executed. After receiving the feedback, the APP prompts the user that "the remote control function is prohibited".

[0076] When the T-BOX determines that the charging status is that the vehicle is plugged into the charging gun, meaning the power battery pack is charging, and determines that the control type corresponding to the remote control command is type two, it determines that the remote control command can be executed. After determining that the remote control command can be executed, the T-BOX sends a first execution signal to the gateway. The gateway receives the first execution signal and forwards it to the vehicle controller. After receiving the first execution signal, the vehicle controller controls the vehicle to execute the remote control function corresponding to the remote control command.

[0077] The first execution signal carries a remote high-voltage power-on signal. After receiving the remote high-voltage power-on signal, the vehicle controller performs remote high-voltage power-on and switches the vehicle's power mode to ON. In this way, the vehicle can be controlled to perform remote control functions corresponding to the remote control command without starting the vehicle (this starting refers to the vehicle's ready-to-start state before the engine starts).

[0078] For example, when a user triggers the remote control function to start the air conditioner via the APP, the APP sends a corresponding remote control command to the T-BOX in response to the triggering of the remote control function, namely, the command to start the air conditioner remotely. After receiving the command to start the air conditioner remotely, the T-BOX determines that the charging status is that the vehicle is plugged into the charging gun. After determining that the control type corresponding to the command to start the air conditioner remotely is the second type, it sends a first execution signal to the gateway. The gateway receives the first execution signal and forwards it to the vehicle controller. After receiving the first execution signal, the vehicle controller performs remote high-voltage power-on and switches the vehicle's power mode to ON. Then it sends a start signal to the air conditioner controller. After responding to the start signal, the air conditioner starts, thereby realizing the remote start of the air conditioner.

[0079] When the T-BOX determines that the charging status is that the vehicle is not plugged into the charging gun, meaning the power battery pack is not charging, it determines that the remote control command can be executed regardless of whether the control type corresponding to the received remote control command is type one or type two. Therefore, in practical implementation, when the T-BOX determines that the charging status is that the vehicle is not plugged into the charging gun, it is not necessary to determine the control type corresponding to the remote control command. After determining that the remote control command can be executed, the T-BOX sends a second execution signal to the gateway. The gateway receives the second execution signal and forwards it to the vehicle controller. After receiving the second execution signal, the vehicle controller controls the vehicle to execute the remote control function corresponding to the remote control command.

[0080] The second execution signal carries a vehicle request signal and a power mode signal. After receiving the vehicle request signal and the power mode signal, the vehicle controller starts the vehicle (this starting refers to the vehicle's ready-to-start state before the engine starts) and then switches the vehicle's power mode to ON, thereby controlling the vehicle to execute the remote control function corresponding to the remote control command.

[0081] For example, when a user triggers the remote control function to start the vehicle via the APP, the APP sends a corresponding remote control command to the T-BOX in response to the triggering of the remote control function, namely the command to start the vehicle remotely. After receiving the command to start the vehicle remotely, the T-BOX determines that the charging status is that the vehicle is not plugged into the charging gun, and then sends a second execution signal to the gateway. The gateway receives the second execution signal and forwards it to the vehicle controller. After receiving the second execution signal, the vehicle controller starts the vehicle (this starting refers to the vehicle's ready-to-start state before the engine starts), then switches the vehicle's power mode to ON, and then sends a start signal to the engine controller. After responding to the start signal, the engine controller starts the engine, thereby realizing the remote starting of the vehicle.

[0082] In an optional implementation, when the charging state is determined to be the state where the vehicle is plugged into the charging gun, and the control type corresponding to the remote control command is determined to be the first type, and the execution of the remote control command is prohibited, the remote control method further includes:

[0083] Send a first prompt message to the user to prompt the user to disconnect the charging gun;

[0084] If the charging gun is detected to be disconnected, the first type of remote control command is executed.

[0085] When the T-BOX determines that the charging status is that the vehicle is plugged into the charging gun, and determines that the control type corresponding to the remote control command is type 1, it determines to prohibit the execution of the remote control command. After determination, it will send a first prompt message to the user terminal, that is, send a first prompt message to the APP, to prompt the user to disconnect the charging gun. After receiving the first prompt message, the APP prompts the user "Please disconnect the charging gun". After receiving the prompt, if the user wants to continue to execute the type 1 remote control command, he / she can trigger the remote control function on the APP again after disconnecting the charging gun. In response to the triggering of the remote control function, the APP sends the corresponding remote control command to the T-BOX, checks the charging status again, and determines that the charging status is that the vehicle is not plugged into the charging gun, that is, the charging gun is disconnected. Then it sends a second execution signal to the gateway. The gateway receives the second execution signal and forwards it to the vehicle controller. After receiving the second execution signal, the vehicle controller starts the vehicle (this starting refers to the vehicle's ready-to-start state before the vehicle engine starts), and then switches the vehicle's power mode to ON, thereby controlling the vehicle to execute the type 1 remote control command.

[0086] In an optional implementation, before determining whether to execute the remote control command based on the charging state and the control type, the remote control method further includes:

[0087] When the charging state is determined to be the state of the charging gun being inserted, a disable command is sent to the user terminal to instruct the user terminal to lock the triggering of the first type of remote control command;

[0088] When the charging state is determined to be the state where the charging gun is not inserted, an unlock command is sent to the user terminal to instruct the user terminal to change the triggering state of the first type of remote control command from the locked state to the unlocked state.

[0089] When the charging status is that the charging gun is plugged in, the vehicle is prohibited from executing Type 1 remote control commands to avoid safety accidents. Therefore, in practice, to improve the user experience, when the charging status is confirmed to be that the charging gun is plugged in, the triggering of Type 1 remote control commands can be locked on the user's end, meaning the user cannot trigger the remote control function corresponding to the Type 1 remote control command on the user's end. Specifically, when the T-BOX confirms that the charging status is that the vehicle is plugged in, it sends a disable command to the user's end, i.e., the APP. After receiving the disable command, the APP locks the triggering of Type 1 remote control commands, thus disabling the remote control function corresponding to the Type 1 remote control command, such as the remote start function of the vehicle. At the same time, the APP will also prompt the user that "the vehicle is plugged in, and some remote functions are disabled." After receiving this prompt, if the user wants to use the remote control function corresponding to the Type 1 remote control command, they can disconnect the charging gun.

[0090] Once it is determined that the charging gun has been disconnected, i.e., the charging status is that the charging gun is not plugged in, the T-BOX sends an unlock command to the user terminal, i.e., the APP. After receiving the unlock command, the APP changes the triggering of the first type of remote control command from the locked state to the unlocked state, so that the user can use the remote control function corresponding to the first type of remote control command, such as the remote control function of remotely starting the vehicle.

[0091] In related technologies, hybrid vehicles, compared to traditional gasoline vehicles, can utilize their battery packs to achieve remote control functions such as remotely starting the air conditioning and remotely cleaning the cabin; compared to pure electric vehicles, hybrid vehicles can start the engine to continue operating when the battery is low when performing remote control functions. Based on this, this invention proposes another remote control method for hybrid vehicles, specifically used when determining that the charging state is that the vehicle is not plugged into the charging gun, and the control type corresponding to the remote control command is the second type, referring to... Figure 2 , Figure 2 This invention illustrates another remote control method for hybrid vehicles according to an embodiment of the present invention, such as... Figure 2 As shown, the remote control method includes:

[0092] Step S201: Obtain the SOC of the power battery pack and the component to be controlled corresponding to the remote control command.

[0093] The components to be controlled are vehicle-mounted components, such as the vehicle's air conditioning, seats, steering wheel, etc.

[0094] When the T-BOX determines that the charging status is that the vehicle is not plugged into the charging gun, and determines that the control type corresponding to the remote control command is the second type, it sends a second execution signal to the gateway. The second execution signal also carries a SOC acquisition signal. The gateway receives the second execution signal and forwards it to the vehicle controller. The vehicle controller receives the second execution signal and sends the SOC acquisition signal to the BMS (Battery Management System). The BMS receives the SOC acquisition signal, acquires the current SOC of the power battery pack, and after acquisition, sends the acquired SOC to the vehicle controller.

[0095] At the same time, T-BOX will also obtain the component to be controlled corresponding to the remote control command. For example, when a user triggers the remote control function of remotely starting the air conditioner in the APP, in response to the triggering of the remote control function, the APP sends the corresponding remote control command to T-BOX, that is, the command to remotely start the air conditioner. After receiving the command to remotely start the air conditioner, T-BOX determines that the component to be controlled corresponding to the command to remotely start the air conditioner is the air conditioner, and forwards the information of the component to be controlled to the vehicle controller through the gateway.

[0096] Step S202: Based on the SOC, determine the starting power supply node when the component to be controlled enters the working state; wherein, the starting power supply node is used to supply power to the component to be controlled.

[0097] Step S203: Connect the starting power supply node to the component to be controlled so that the component to be controlled enters the working state.

[0098] After receiving the SOC from the BMS and the information of the controlled component forwarded by the gateway, the vehicle controller determines the starting power supply node for the controlled component to enter the working state and establishes the path between the starting power supply node and the controlled component to enable the controlled component to enter the working state. For example, when a user triggers the remote control function to start the air conditioner via the APP, in response to the triggering of this remote control function, the APP sends the corresponding remote control command to the T-BOX, i.e., the command to remotely start the air conditioner. After receiving the command, the T-BOX determines that the charging status is that the vehicle is not plugged into the charging gun, and then sends a second execution signal to the gateway. The gateway receives the second execution signal and forwards it to the vehicle controller. After receiving the second execution signal, the vehicle controller starts the vehicle (this starting refers to the vehicle's ready-to-start state before the engine starts) and then switches the vehicle's power mode to ON. Simultaneously, the vehicle controller sends a SOC acquisition signal to the BMS. The BMS receives the SOC acquisition signal to acquire the current SOC of the power battery pack. After acquisition, it sends the acquired SOC to the vehicle controller. Upon receiving the SOC, the vehicle controller determines the starting power supply node when the controlled component enters the working state, i.e., the starting power supply node when the air conditioner enters the working state, and connects the starting power supply node to the air conditioner to start the air conditioner, thereby realizing remote start of the air conditioner.

[0099] In one optional implementation, based on the SOC, determining the starting power supply node when the controlled component enters the working state includes:

[0100] When the SOC is not lower than the preset SOC, the starting power supply node is determined to be the power battery pack;

[0101] When the SOC is lower than the preset SOC, the starting power supply node is determined to be the vehicle's engine.

[0102] When the vehicle controller receives the SOC sent by the BMS, it determines whether the SOC is lower than the preset SOC. If it is not lower, it means that the current SOC of the power battery pack is sufficient for the controlled component to enter the working state. In this case, the starting power supply node for the controlled component to enter the working state is the power battery pack. If it is lower, it means that the current SOC of the power battery pack is insufficient for the controlled component to enter the working state. In this case, the starting power supply node for the controlled component to enter the working state is the engine. Specifically, this starting power supply node is the generator connected to the engine. When the engine starts, it drives the generator to rotate, thereby supplying power to the controlled component.

[0103] The preset SOC can be determined according to the actual vehicle model. In this embodiment of the invention, the preset SOC is set to 15%.

[0104] Upon receiving a remote control command for a vehicle, this embodiment of the invention first determines the charging status of the power battery pack, i.e., whether the vehicle is plugged into a charging gun to charge the power battery pack. Simultaneously, it determines the control type corresponding to the remote control command, thereby determining whether the remote control command can be executed. This ensures that all remote control functions of the vehicle can be executed even when the vehicle is not plugged into a charging gun to charge the power battery pack. Furthermore, when executing the remote control function corresponding to a second type of remote control command, the power battery's charge can be used preferentially; when the power battery charge is low, the engine is started to continue executing the remote control function. When the vehicle is plugged into a charging gun to charge the power battery pack, and the control type of the remote control command is determined to be the second type, only high voltage needs to be supplied to the vehicle; the engine does not need to be started, thus realizing the corresponding remote control function.

[0105] Based on the same inventive concept, embodiments of the present invention also propose a remote control device for a hybrid vehicle, which refers to... Figure 3 , Figure 3 A block diagram of a remote control device for a hybrid vehicle according to an embodiment of the present invention is shown, as follows. Figure 3 As shown, the remote control device 1 includes:

[0106] The first determining unit 101 is used to determine the charging status of the vehicle's power battery pack and the control type corresponding to the remote control command when it receives a remote control command for the vehicle.

[0107] In practical implementation, users can trigger the remote control function through the APP. In response to the triggering of this remote control function, the APP sends a corresponding remote control command to the vehicle. For example, after the user triggers the remote start function of the vehicle through the APP, the APP sends a command to start the vehicle. Specifically, the APP sends the remote control command to the first determining unit 101. After receiving the remote control command, the first determining unit 101 first checks the charging status of the power battery pack to determine the charging status of the power battery pack. This charging status refers to whether the vehicle is plugged into the charging gun or not plugged into the charging gun, that is, whether the power battery pack is charging or not. At the same time, the first determining unit 101 also determines the control type corresponding to the remote control command.

[0108] The remote control commands correspond to two types of control types: one type controls the entire vehicle, such as remotely starting the vehicle and remotely parking the vehicle; the other type controls components on the vehicle, such as controlling the air conditioning, seats, steering wheel, etc. Specifically, this could be a command to remotely start the air conditioning, a command to remotely clean the cabin, a command to remotely turn on the seat heating and ventilation, and a command to remotely turn on the steering wheel heating, etc.

[0109] The second determining unit 102 is used to determine whether to execute the remote control command based on the charging state and the control type.

[0110] The second determining unit 102 determines whether to execute the received remote control command based on the determined charging state and control type. If execution is required, an execution signal is sent to the second sub-determining unit, which receives the execution signal and forwards it to the control unit 103; if execution is not required, feedback is sent to the APP, which then prompts the user that "remote control function is disabled".

[0111] The control unit 103 is used to control the vehicle to perform a remote control function corresponding to the control type when executing the remote control command.

[0112] After receiving the execution signal from the second sub-determining unit, the control unit 103 controls the vehicle to execute the remote control function corresponding to the remote control command. For example, if the user triggers a remote control function via the app to remotely start the vehicle, the control unit 103, upon receiving the execution signal, will send a start signal to the engine controller. The engine controller, in response to this start signal, will start the engine, thus achieving remote vehicle start. Alternatively, if the user triggers a remote control function via the app to remotely start the air conditioning, the vehicle controller, upon receiving the execution signal, will send a start signal to the air conditioning controller. The air conditioning controller, in response to this start signal, will start the air conditioning, thus achieving remote air conditioning start.

[0113] Based on the same inventive concept, this invention also proposes a vehicle, which includes a control module for implementing the above-described remote control method.

[0114] As the device embodiment is basically similar to the method embodiment, the description is relatively simple, and relevant parts can be found in the description of the method embodiment.

[0115] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present invention.

[0117] It should also be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations, nor should they be construed as indicating or implying relative importance. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes the element.
