Description

Technical Field

[0001] This invention relates to the field of intelligent connected vehicle technology, and in particular to a method and system for remote vehicle control. Background Technology

[0002] With the development of intelligent connected vehicle technology, remote vehicle control via mobile applications, such as remotely turning on the air conditioning, has become a common need. Users have increasingly higher expectations for the response speed of remote control commands.

[0003] In existing technologies, different remote control power-on / off strategies exist. One strategy, aiming for rapid response, immediately uses the vehicle's low-voltage power supply to start the target device after the vehicle-to-everything (V2X) device receives a remote command and requests power on. While this strategy offers fast response, it poses a serious safety hazard. Because the vehicle's high-voltage power supply system has not yet completed its power-on and self-test at this time, its successful readiness is unknown. If the high-voltage power supply system subsequently fails to power on, the high-power device, entirely powered by the low-voltage supply, will continuously consume power, potentially leading to a power outage of the low-voltage power supply and rendering the vehicle unable to start.

[0004] To avoid the aforementioned power outage risks, a more common strategy employs a conservative "confirm first, then execute" approach. In this strategy, after requesting power to the vehicle, the onboard control unit continuously waits and monitors the status of the high-voltage power supply system. Only after confirming that the high-voltage power supply system (e.g., its internal DC-DC converter) is ready does it issue a command to activate the target device. While this strategy ensures the vehicle's electrical safety, the fact that the high-voltage power supply system requires several seconds or even longer to complete its power-on preparation process results in a significant delay between the user issuing the command and the target device actually operating, severely impacting the immediacy of remote control functions and the user experience.

[0005] Therefore, existing technologies struggle to balance remote control response speed and vehicle electrical safety, presenting a pressing technical challenge. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a method and system for remote vehicle control.

[0007] In a first aspect, embodiments of the present invention provide a vehicle remote control method, applied to a vehicle including a low-voltage power supply module and a high-voltage power supply system, the method comprising:

[0008] In response to a remote control command from the user terminal, after the vehicle has completed the power-on operation and before confirming that the high-voltage power supply system is ready, the target vehicle equipment is started using the low-voltage power supply module.

[0009] After the vehicle completes the power-on operation, the vehicle is driven into a high-voltage state, and the high-voltage power supply system is used to supply power to the target vehicle-mounted equipment.

[0010] Real-time monitoring of feedback signals characterizing the operating status of the high-voltage power supply system;

[0011] If the feedback signal indicates that the high-voltage power supply system is working normally within the preset time window, then the operation of the target vehicle-mounted equipment will be maintained.

[0012] If, within the preset time window, the feedback signal indicates that the high-voltage power supply system is malfunctioning, the target vehicle-mounted equipment will be stopped, and the vehicle will be powered off.

[0013] Furthermore, before starting the target vehicle-mounted equipment using the low-voltage power supply module, the method further includes:

[0014] The cloud platform responds to remote control commands from the user terminal and monitors whether the vehicle network terminal is online;

[0015] If the vehicle network terminal is offline, a wake-up request is sent to the vehicle network terminal. The vehicle network terminal responds to the wake-up request and goes online, updating its status to online.

[0016] If the vehicle network terminal is online, it establishes and / or maintains a long-term connection with the cloud platform for a preset time period.

[0017] Furthermore, the step of responding to a remote control command from the user terminal, and after the vehicle has completed its power-on operation but before confirming that the high-voltage power supply module is ready, to start the target vehicle-mounted equipment using the low-voltage power supply module, includes:

[0018] The vehicle network terminal responds to the remote control command from the cloud platform by sending a wake-up request to the vehicle control module and performing communication authentication with the vehicle control module.

[0019] After the communication authentication is successful, the vehicle network terminal sends a vehicle power-on request to the vehicle control module;

[0020] The vehicle control module responds to the vehicle power-on request, controls the vehicle to power on, and sends a power-on feedback signal to the vehicle network terminal.

[0021] In response to the power-on feedback signal, the vehicle network terminal sends control commands to the vehicle control module for the target vehicle device.

[0022] The vehicle control module responds to the control command to start the target vehicle-mounted device and feeds back the start status of the target vehicle-mounted device to the vehicle networking device;

[0023] The vehicle networking device controls the low-voltage power supply module to supply power to the target vehicle-mounted device.

[0024] Furthermore, the step of driving the vehicle into a high-voltage state after the vehicle completes the power-on operation and using the high-voltage power supply system to supply power to the target vehicle-mounted equipment includes:

[0025] The power control module responds to the network signal feedback when the vehicle is powered on, and drives the DC-DC converter module to control the relay to engage so that the vehicle enters a high-voltage state.

[0026] The vehicle networking device responds to the relay activation state of the DC drive module by switching the high-voltage power supply module to supply power to the target vehicle device.

[0027] Furthermore, the feedback signal characterizing the operating status of the high-voltage power supply system under real-time monitoring includes:

[0028] The vehicle networking device acquires feedback signals for real-time monitoring of the operating status of the DC drive module.

[0029] Furthermore, the step of maintaining the operation of the target vehicle-mounted equipment if the feedback signal indicates that the high-voltage power supply system is working normally within a preset time window includes:

[0030] The vehicle networking device determines the working status of the DC drive module based on the feedback signal;

[0031] If the DC drive module continues to work normally, the operation of the target vehicle equipment is maintained, and the high-voltage power supply module continues to supply power to the target vehicle equipment.

[0032] If the DC drive module malfunctions, a timer is started. If the DC drive module recovers its normal operation within a preset time window, the timer is reset to zero, maintaining the operation of the target vehicle-mounted device. At the same time, the high-voltage power supply module continues to supply power to the target vehicle-mounted device.

[0033] Furthermore, if, within the preset time window, the feedback signal indicates that the high-voltage power supply system is malfunctioning, the target vehicle-mounted equipment is stopped, and the vehicle is powered down, the following steps are taken:

[0034] The vehicle networking device determines the working status of the DC drive module based on the feedback signal;

[0035] If the DC drive module malfunctions, a timer is started. If the DC drive module continues to malfunction within a preset time window, the low-voltage power supply module is immediately switched to supply power to the target vehicle equipment, and a shutdown command for the target vehicle equipment is issued to the body control module.

[0036] The vehicle control module responds to the shutdown command by controlling the target vehicle-mounted equipment to stop operating and feeding back the shutdown status of the target vehicle-mounted equipment to the vehicle networking device.

[0037] In response to the shutdown state of the target vehicle-mounted device, the vehicle networking device sends a vehicle power-off command to the body control module;

[0038] The vehicle control module responds to the vehicle power-down command by controlling the vehicle to perform a power-down operation and sends a power-down feedback signal to the vehicle networking device.

[0039] Furthermore, if, within the preset time window, the feedback signal indicates that the high-voltage power supply system is malfunctioning, and the target vehicle-mounted equipment is stopped and the vehicle is powered down, the method further includes:

[0040] The vehicle networking device pushes air conditioning shutdown information and / or power supply abnormality information to the user terminal;

[0041] And / or,

[0042] If the vehicle network terminal sends a vehicle power-on request to the body control module but does not receive a power-on feedback signal from the body control module, it pushes a power-on failure message to the user terminal.

[0043] Furthermore, the method also includes:

[0044] If the vehicle control module does not receive a vehicle power-down command from the vehicle network device after responding to the shutdown command and controlling the target vehicle-mounted equipment to stop operating, it will control the vehicle to perform a power-down operation when it detects that the power of the low-voltage power supply module is lower than a preset threshold.

[0045] Secondly, embodiments of the present invention provide a vehicle remote control system, including a vehicle networking terminal, a low-voltage power supply module, a body control module, a high-voltage power supply system, a target vehicle-mounted device, and a user terminal;

[0046] The user terminal is used to send remote control commands to the vehicle network terminal;

[0047] The vehicle network terminal is used to respond to the remote control command, control the vehicle body control module to drive the vehicle to power on, and start the target vehicle equipment using the low-voltage power supply module before confirming that the high-voltage power supply system is ready.

[0048] The high-voltage power supply system is used to drive the vehicle into a high-voltage state after the vehicle completes the power-on operation and to supply power to the target vehicle-mounted equipment.

[0049] The vehicle networking device is used to monitor feedback signals that characterize the working status of the high-voltage power supply system in real time; when the feedback signal indicates that the high-voltage power supply system is working normally within a preset time window, the operation of the target vehicle-mounted device is maintained; when the feedback signal indicates that the high-voltage power supply system is working abnormally within the preset time window, the target vehicle-mounted device is controlled to stop operating, and the vehicle is controlled to perform a power-off operation.

[0050] This invention provides a vehicle remote control method, comprising: responding to a remote control command from a user terminal, after the vehicle completes a power-on operation but before confirming the high-voltage power supply system is ready, starting a target vehicle-mounted device using a low-voltage power supply module; after the vehicle completes a power-on operation, driving the vehicle into a high-voltage state and using the high-voltage power supply system to supply power to the target vehicle-mounted device; real-time monitoring of feedback signals characterizing the operating status of the high-voltage power supply system; if, within a preset time window, the feedback signal indicates that the high-voltage power supply system is operating normally, maintaining the operation of the target vehicle-mounted device; if, within the preset time window, the feedback signal indicates that the high-voltage power supply system is operating abnormally, controlling the target vehicle-mounted device to stop operating and controlling the vehicle to perform a power-off operation. Thus, through asynchronous fast start and safe rollback mechanisms, while ensuring vehicle electrical safety and avoiding low-voltage power supply failure, the response time of remote control is significantly shortened, improving the user experience.

[0056] To enable those skilled in the art to better understand the technical solutions of the present invention, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0057] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0058] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0059] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded. Terms such as “connected” or “linked” are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect.

[0060] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0061] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example: appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely locating a specific individual.

[0062] In related technologies, there are two main methods for remote vehicle control: The first method involves switching the power state to the ON position and issuing a command to turn on the target vehicle equipment. However, since the vehicle is not connected to high voltage, there is a risk of low-voltage battery depletion due to high-voltage power-on failure. The second method involves issuing a remote power-on command, receiving the working status of the DC-DC drive module, and then issuing control commands for the target vehicle equipment after it is working normally. This method results in a long remote control time and a poor user experience because the relay of the DC-DC drive module has a long engagement time.

[0063] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a method for remote vehicle control. For example... Figure 1 As shown, the vehicle remote control method provided in this embodiment of the invention may include at least the following steps S101~S105:

[0064] Step S101: In response to a remote control command from the user terminal, after the vehicle has completed the power-on operation and before confirming that the high-voltage power supply system is ready, the target vehicle-mounted equipment is started using the low-voltage power supply module.

[0065] The vehicle remote control method provided in this embodiment of the invention covers the complete link from the user end to the vehicle end, including the user-side mobile terminal APP, cloud platform, and vehicle-to-everything (V2X) terminal.

[0066] In practical applications, the car brand's mobile app installed on the user's mobile terminal serves as the user terminal, allowing users to send remote control commands to the vehicle. Taking air conditioning-related commands as an example, the app can provide access to remotely control the air conditioning to turn on / off, set the temperature and mode, and provide prompts and updates to the status displayed on the app based on the control results.

[0067] Before starting the target vehicle device based on remote control commands, the cloud platform can respond to remote control commands from the user terminal and monitor whether the vehicle network terminal is online. If the vehicle network terminal is offline, a wake-up request is sent to the vehicle network terminal. The vehicle network terminal responds to the wake-up request to go online and updates its status to online. If the vehicle network terminal is online, a long connection with the cloud platform is established and / or maintained for a preset time period.

[0068] It's understandable that after a user registers, activates, and binds the target vehicle to the app, the user can issue remote control commands through the app. For example, a user could issue an air conditioning control command, calling the cloud platform to control the air conditioning to turn on and set the temperature. The vehicle network terminal, as the main control unit for remote control, is responsible for sending network wake-up requests, power-on / off requests, processing remote control commands, and monitoring the operating status of the DC-DC converter module (DCDC). The cloud platform determines whether the vehicle network terminal (TBOX) is online by monitoring its heartbeat messages. If it's offline, it sends a wake-up SMS and an MQTT wake-up request. Once the vehicle network terminal is online, it updates its status to online and establishes a long-term connection with the cloud platform. It should be noted that, under normal circumstances, the vehicle network terminal maintains a long-term connection with the platform by default. If the vehicle network terminal remains unwoke for 7 consecutive days, the cloud platform releases the long-term connection with the vehicle network terminal to reduce the impact of dark current on the vehicle's range.

[0069] like Figure 2 The diagram shows the module interaction link for remote vehicle control. After the vehicle network terminal receives the remote control command from the cloud platform, it responds by sending a wake-up request to the body control module and performing communication authentication with the body control module. After successful authentication, the vehicle network terminal sends a vehicle power-on request to the body control module (VIU). The body control module responds to the power-on request by powering on the vehicle and sends a power-on feedback signal to the vehicle network terminal. The vehicle network terminal responds to the power-on feedback signal by issuing control commands to the body control module for the target vehicle-mounted device. The body control module responds to the control commands by starting the target vehicle-mounted device and sends feedback on the start-up status of the target vehicle-mounted device to the vehicle network device. The vehicle network device controls the low-voltage power supply module to supply power to the target vehicle-mounted device.

[0070] In this embodiment of the invention, the vehicle body control module (VIU) is used to manage and control most of the low-voltage-compatible electrical loads of the vehicle, such as headlights, windows, and air conditioning. After receiving a remote control command from the cloud platform, the vehicle network terminal sends a wake-up request to the VUI and performs communication authentication. After successful authentication, it sends a remote power-on request to the VUI. Upon receiving the request, the VUI controls the vehicle to switch from the OFF position to the ON position. The VUI receives power-on feedback and then sends a remote air conditioning start command, which the VUI controls to turn on the air conditioning. Since the VUI is not yet connected to high voltage, a low-voltage power supply module (such as...) can be used at this time. Figure 2 The battery in the system powers the air conditioner.

[0071] Step S102: After the vehicle completes the power-on operation, drive the vehicle into a high-voltage state and use the high-voltage power supply system to supply power to the target vehicle equipment.

[0072] The high-voltage power supply system in this embodiment of the invention includes a power control unit (PDCU), a direct current converter (DCDC), and a high-voltage power supply module (such as...). Figure 2 (Powered by the vehicle's power battery). The power control module, as the core control unit of the vehicle's power system, manages the power-on and power-off processes of the high-voltage power supply system. The DC-DC converter module can be used to control the engagement state of the vehicle's relays to achieve high-voltage power-on and power-off.

[0073] like Figure 2 As shown, the power control module responds to the network signal feedback when the vehicle is powered on, and drives the DC-DC converter module to control the relay to engage, so that the vehicle enters a high-voltage state; the vehicle networking equipment responds to the relay engagement state of the DC drive module, and switches the high-voltage power supply module to supply power to the target vehicle equipment.

[0074] In this step, after the vehicle body control module controls the vehicle to the ON position, the power control module controls the vehicle to apply high voltage based on the network signal feedback from the vehicle's power-on, so that the DC-DC converter module controls the relay to engage and provides feedback on the normal working status. At this time, the high-voltage power supply module (such as the power battery) supplies power to the air conditioner.

[0075] Step S103: Real-time monitoring of feedback signals characterizing the working status of the high-voltage power supply system.

[0076] In this step, the vehicle-to-everything (V2X) device acquires feedback signals for real-time monitoring of the operating status of the DC drive module.

[0077] Step S104: If the feedback signal indicates that the high-voltage power supply system is working normally within the preset time window, then the operation of the target vehicle-mounted equipment shall be maintained.

[0078] Specifically, the vehicle-to-everything (V2X) device determines the operating status of the DC drive module based on feedback signals. If the DC drive module continues to operate normally, the operation of the target vehicle-mounted device is maintained, and the high-voltage power supply module continues to supply power to the target vehicle-mounted device. If the DC drive module malfunctions, a timer is started. If the DC drive module recovers to normal operation within a preset time window, the timer is reset to zero, the operation of the target vehicle-mounted device is maintained, and the high-voltage power supply module continues to supply power to the target vehicle-mounted device.

[0079] Step S105: If, within the preset time window, the feedback signal indicates that the high-voltage power supply system is malfunctioning, control the target vehicle-mounted equipment to stop operating and control the vehicle to perform a power-off operation.

[0080] Specifically, the vehicle-to-everything (V2X) device determines the operating status of the DC drive module based on feedback signals. If the DC drive module malfunctions, a timer is started. If the DC drive module continues to malfunction within a preset time window, the low-voltage power supply module is immediately switched to supply power to the target vehicle-mounted device, and a shutdown command is sent to the body control module for the target vehicle-mounted device. In response to the shutdown command, the body control module controls the target vehicle-mounted device to stop operating and sends feedback on the shutdown status of the target vehicle-mounted device to the V2X device. In response to the shutdown status of the target vehicle-mounted device, the V2X device sends a vehicle power-down command to the body control module. In response to the vehicle power-down command, the body control module controls the vehicle to perform a power-down operation and sends a power-down feedback signal to the V2X device.

[0081] Preferably, the preset time window can be 5 seconds. That is, the vehicle networking device continuously judges the working status of the DC drive module based on the feedback signal. If the working status is normal, the air conditioner will continue to be turned on according to the remote control function design. If the working status of the DC drive module is abnormal during the continuous operation of the air conditioner, a timer will be started. If the monitoring time is less than 5 seconds, the working status of the DC drive module will return to normal, the timer will be reset, and the air conditioner will continue to work according to the remote control command and the timer. If the monitoring time reaches 5 seconds and the DC drive module continues to be abnormal, it is considered that the high voltage power supply is abnormal. At this time, the low voltage power supply module (battery) will be switched to supply power to the air conditioner.

[0082] At this point, to prevent battery depletion, if the vehicle-to-everything (V2X) device detects an abnormal operation of the DC drive module for 5 seconds, it issues a remote air conditioning shutdown command. Upon receiving the command, the vehicle control module shuts down the air conditioning and sends a shutdown status update to the V2X device. Then, upon receiving the shutdown feedback, the V2X device sends a remote vehicle power-off request to the vehicle control module. The vehicle control module then powers down the vehicle and sends a successful remote power-off message back to the V2X device.

[0083] like Figure 3As shown, after controlling the vehicle to perform a power-down operation, this embodiment of the invention may further include step S106, whereby the vehicle networking device pushes air conditioning shutdown information and / or power supply anomaly information to the user terminal. The user's mobile terminal can display relevant content through information push and in-site messages from the brand's APP.

[0084] It is understood that the following two abnormal situations may occur during the remote control of the vehicle, and the embodiments of the present invention also provide special handling mechanisms for abnormal situations:

[0085] Mechanism 1: If the vehicle network terminal sends a vehicle power-on request to the body control module but does not receive a power-on feedback signal from the body control module, it will push a power-on failure message to the user terminal.

[0086] This situation occurs when a remote power-on request is sent from the vehicle-to-everything (V2X) terminal, but due to communication loss or other reasons, the vehicle control module does not receive the power-on request, and the V2X terminal does not receive power-on feedback. In this case, the V2X terminal pushes an abnormal power-on reminder to the brand's APP to remind the user that the remote control has failed.

[0087] Mechanism 2: If the vehicle control module responds to the shutdown command and controls the target on-board equipment to stop operating, but does not receive a vehicle power-off command from the vehicle network equipment, it will control the vehicle to perform a power-off operation when it detects that the power of the low-voltage power supply module is lower than a preset threshold.

[0088] In the event of a power supply abnormality during air conditioning operation, which necessitates remote control to shut down the air conditioning but fails to power down, the vehicle control module will monitor the battery level and, if it detects that the battery level has reached a threshold (e.g., 10% of the total battery level), control the vehicle to power down.

[0089] This invention provides a vehicle remote control method applied to a vehicle including a low-voltage power supply module and a high-voltage power supply system. The method includes: responding to a remote control command from a user terminal, after the vehicle completes a power-on operation but before confirming the high-voltage power supply system is ready, starting a target vehicle-mounted device using the low-voltage power supply module; after the vehicle completes the power-on operation, driving the vehicle into a high-voltage state and using the high-voltage power supply system to supply power to the target vehicle-mounted device; real-time monitoring of feedback signals characterizing the operating status of the high-voltage power supply system; if the feedback signal indicates that the high-voltage power supply system is operating normally within a preset time window, maintaining the operation of the target vehicle-mounted device; if the feedback signal indicates that the high-voltage power supply system is operating abnormally within the preset time window, controlling the target vehicle-mounted device to stop operating and controlling the vehicle to perform a power-off operation. Compared with the prior art, this invention has at least the following beneficial effects:

[0090] 1) Shorten response time and improve user experience: Through the asynchronous control strategy of "execute first and confirm later", the target device is started immediately with low voltage power supply after receiving the remote command, without waiting for the high voltage system to be ready, which greatly shortens the user's waiting time and significantly improves the instant response experience of remote control.

[0091] 2) Ensure vehicle electrical safety and avoid power outage risk: This application designs a dynamic monitoring and anomaly handling mechanism based on high voltage ready state. By setting a time window to judge the high voltage power supply status, once it is confirmed that the high voltage power supply is continuously abnormal within a specified time, the system will actively shut down the equipment and power off the vehicle, thereby completely eliminating the risk of low voltage power outage due to high voltage power failure and solving the safety hazards of existing rapid response strategies.

[0092] 3) Improve system robustness and reliability: Through continuous monitoring of the ready state signal and the timer clearing mechanism, the power supply status jump caused by signal jitter or brief system anomalies can be effectively filtered out, avoiding false interruptions to remote control tasks and making the entire control process more stable and reliable.

[0093] Based on the same inventive concept, as Figure 1 In a specific implementation, this invention also provides a vehicle remote control system, such as... Figure 4 As shown, the system may include: a vehicle networking terminal 410, a low-voltage power supply module 420, a vehicle body control module 430, a high-voltage power supply system 440, a target vehicle-mounted device 450, and a user terminal 460.

[0094] Among them, the user terminal 460 can be used to send remote control commands to the vehicle networking terminal 410;

[0095] The vehicle networking terminal 410 can be used to respond to remote control commands, control the vehicle control module 430 to power on the vehicle, and start the target vehicle equipment 450 using the low-voltage power supply module 420 before confirming that the high-voltage power supply system 440 is ready.

[0096] The high-voltage power supply system 440 can be used to drive the vehicle into a high-voltage state after the vehicle has completed the power-on operation and to supply power to the target vehicle equipment 450.

[0097] The vehicle networking device 410 can be used to monitor feedback signals that characterize the working status of the high-voltage power supply system 440 in real time; when the feedback signal indicates that the high-voltage power supply system 440 is working normally within a preset time window, the operation of the target vehicle-mounted device 450 is maintained; when the feedback signal indicates that the high-voltage power supply system 440 is working abnormally within a preset time window, the target vehicle-mounted device 450 is controlled to stop operating, and the vehicle is controlled to perform a power-off operation.

[0098] like Figure 5As shown, the high-voltage power supply system 440 may include a power control module 441, a DC-DC conversion module 442, and a high-voltage power supply module 443, which work together to achieve... Figure 1 The vehicle remote control method shown.

[0099] It should be noted that other corresponding descriptions of the functional modules involved in the vehicle remote control system provided in this embodiment of the invention can be found in [reference needed]. Figure 1 The corresponding description of the method shown will not be repeated here.

[0100] Those skilled in the art will understand that all or some of the steps, systems, and apparatuses disclosed above, and their functional modules / units, can be implemented as software, firmware, hardware, or suitable combinations thereof. In hardware implementations, the division between functional modules / units mentioned above does not necessarily correspond to the division of physical components; for example, a physical component may have multiple functions, or a function or step may be performed collaboratively by several physical components. Some or all physical components may be implemented as software executed by a processor, such as a central processing unit, digital signal processor, or microprocessor, or as hardware, or as an integrated circuit, such as an application-specific integrated circuit (ASIC).
