DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] First, some technical terms in this application are explained to facilitate those skilled in the art to understand this application.

[0020] Telematics Box (TBOX): An intelligent device installed in a vehicle, primarily responsible for data communication between the vehicle and the outside world. By integrating multiple sensors and communication technologies, the TBOX collects real-time vehicle status information, such as speed and location, and transmits this information to a remote service center or the owner's mobile app. It can also receive control commands from the remote service center, enabling remote control of the vehicle.

[0021] Telematics Service Provider (TSP): A remote service platform that provides connected vehicle services. Its main function is to collect and supply data between vehicles and service providers, and provide car owners with a variety of services.

[0022] First, please refer to Figure 1 , Figure 1 This is a flowchart of a remote car locking method according to an embodiment of the present application. The remote car locking method provided in this embodiment includes the following steps: Step S1: The vehicle terminal receives a vehicle locking instruction issued by the vehicle remote service provider, wherein the vehicle locking instruction includes a set opening of the accelerator pedal.

[0023] Step S2: The vehicle-mounted terminal converts the set opening of the accelerator pedal into a voltage signal.

[0024] Step S3: adjusting the opening of the accelerator pedal based on the voltage signal so that the opening of the accelerator pedal is consistent with the set opening of the accelerator pedal, while shielding the input signal of the mechanical accelerator pedal and locking the vehicle.

[0025] This embodiment receives a vehicle lock command issued by a remote vehicle service provider through an on-board terminal, then converts the set opening of the accelerator pedal in the vehicle lock command into a voltage signal, and adjusts the opening of the accelerator pedal based on the voltage signal to make the opening of the accelerator pedal consistent with the set opening of the accelerator pedal. By controlling the opening of the accelerator pedal, the vehicle engine is indirectly controlled, and the input signal of the mechanical accelerator pedal is shielded, so that the driver cannot affect the vehicle locking through the mechanical accelerator pedal. In this way, the purpose of locking the vehicle is achieved, various problems caused by directly controlling the engine to lock the vehicle are avoided, and there is no need to adapt the engine protocol according to different engine manufacturers, thereby reducing the development cost of the vehicle manufacturer.

[0026] Before starting step S1, the remote vehicle service provider must first send a lock activation command to the vehicle terminal. This command contains a specific command code and encrypted information to ensure command security. Upon receiving the lock activation command, the vehicle terminal decodes and verifies its security. If the command is valid and legal, the vehicle terminal activates the remote lock function and continues to receive subsequent lock commands from the remote vehicle service provider. If the command is illegal or invalid, the vehicle terminal will not activate the remote lock function and will send an error report to the remote vehicle service provider.

[0027] Because the locking function is closely related to the user's actual vehicle usage, for example, different users may have different vehicle safety requirements, or remote locking may not be suitable in certain scenarios. Therefore, during normal vehicle operation, the locking function is disabled by default.

[0028] In some embodiments, in the above step S1, after the vehicle terminal receives the vehicle lock instruction issued by the vehicle remote service provider, the following steps may be further performed: Based on the preset verification algorithm and secret key, the vehicle locking command is security verified.

[0029] If the safety check passes, the set opening of the accelerator pedal is converted into a voltage signal.

[0030] If the security check fails, the vehicle terminal sends a check failure message to the vehicle remote service provider.

[0031] In this embodiment, the pre-set verification algorithms include, but are not limited to, cyclic redundancy check (CRC), hash algorithms (MD5 or SHA-256), and exclusive OR (XOR). The key is managed by the vehicle telematics service provider and shared with the vehicle terminal through a secure key distribution mechanism.

[0032] To further improve security, automotive remote service providers should regularly update secret keys and share new secret keys with vehicle terminals to reduce security risks caused by key leakage.

[0033] After the security check is completed, if the verification result shows that the vehicle lock command is legal and has not been tampered with, it means that the security check has passed, and the vehicle terminal will continue to execute the subsequent operations of the vehicle lock command, including but not limited to converting the set accelerator pedal opening in the vehicle lock command into a voltage signal. If the verification result shows that the vehicle lock command has been tampered with or comes from an illegal vehicle remote service provider, it means that the security check has failed. The vehicle terminal will not execute the vehicle lock command and will send a verification failure message to the vehicle remote service provider. Regardless of whether the security check passes or fails, the vehicle terminal will record relevant information about the security check, including but not limited to the content of the vehicle lock command, the verification result, and the timestamp of the verification.

[0034] It should be noted that security verification of the vehicle locking command through a preset verification algorithm and secret key can effectively prevent unauthorized access or execution of malicious commands, and protect the vehicle from hacker attacks or illegal operations.

[0035] In some embodiments, in step S2, converting the set opening of the accelerator pedal into a voltage signal includes the following steps: S21: Determine a mapping relationship between the set opening of the accelerator pedal and the voltage signal based on the vehicle operating voltage.

[0036] S22: Convert the set opening of the accelerator pedal into a voltage signal according to the mapping relationship.

[0037] In step S21, when setting the mapping relationship between the accelerator pedal's set opening and the voltage signal, a certain safety margin must be considered. The upper and lower limits of the voltage signal are slightly lower than the vehicle's actual operating voltage range to prevent signal distortion due to voltage fluctuations or component aging. The mapping relationship between the accelerator pedal's set opening and the voltage signal can be linear or nonlinear, depending on the specific vehicle control requirements.

[0038] In step S22, after converting the set accelerator pedal opening into a voltage signal based on the mapping relationship, it is necessary to ensure that the minimum output voltage does not fall below the preset safety voltage threshold. To precisely control the effective value of the output voltage, the output voltage is step-cut. The purpose of step-cutting is to divide the continuous voltage signal into a number of discrete voltage steps, each corresponding to a specific accelerator pedal opening range. By step-cutting the output voltage, the continuous input accelerator pedal opening can be converted into a discrete voltage output, thereby achieving precise control of the vehicle power system.

[0039] In some embodiments, the vehicle locking instruction includes a locking duration. After the vehicle is locked, the vehicle terminal starts counting. When the counting duration equals the locking duration, the mechanical accelerator pedal input signal is unblocked, and the vehicle is no longer locked.

[0040] The aforementioned lock duration includes a lock start time and an end time. The lock start time can be the current time or a future time. When the lock start time is reached, the vehicle is locked and the onboard terminal begins counting. When the countdown equals the lock duration, i.e., the lock end time is reached, the mechanical accelerator pedal input signal is unblocked and the vehicle is no longer locked.

[0041] If the vehicle is powered off before the end time of the lock, the vehicle terminal will calculate the actual lock duration of this time, that is, the current time minus the lock start time, and save this data. When the vehicle is powered on again, the vehicle terminal will recalculate the lock end time based on the actual lock duration of the last time.

[0042] In some embodiments, when the automobile remote service provider detects that the vehicle terminal has been illegally hacked, the process further includes: The opening of the accelerator pedal is adjusted to a preset opening, wherein the illegal hacking methods include but are not limited to unplugging the vehicle terminal, or flashing the computing chip associated with the vehicle terminal.

[0043] In this embodiment, the preset opening is preferably set at 10% of the maximum accelerator pedal opening. Even if the vehicle is illegally controlled, its acceleration capability is significantly limited, thereby reducing the risk of loss of control due to malicious acceleration. Furthermore, a 10% accelerator pedal opening also partially retains the vehicle's mobility, facilitating movement to a safe location in an emergency.

[0044] When the automotive remote service provider detects that the vehicle terminal has been illegally hacked, the automotive remote service provider will record the time of the illegal hacking and the location of the vehicle, so that the owner or maintenance personnel can quickly locate the vehicle and restore the normal operating functions of the vehicle.

[0045] In some embodiments, before adjusting the accelerator pedal opening based on the voltage signal in step S3, the process further includes: Detect the driving status of the vehicle. If the vehicle is in an emergency braking state, stop adjusting the opening of the accelerator pedal. After the vehicle's emergency braking is completed, adjust the opening of the accelerator pedal.

[0046] Specifically, this method utilizes the vehicle's built-in sensor network, including but not limited to speed sensors, acceleration sensors, and brake system status sensors to monitor the vehicle's driving status in real time. When it is detected that the vehicle is in an emergency braking state (such as a rapid increase in deceleration), in order to protect the lives of people in the vehicle, any adjustment of the accelerator pedal opening will be temporarily stopped to ensure that the vehicle can quickly decelerate in an emergency and avoid potential collision risks.

[0047] After the emergency braking is complete, the method continues to monitor the vehicle's driving state. When it detects that the vehicle's speed is stable and no new emergency braking signals are generated, it is considered that the vehicle has exited the emergency braking state. At this point, the method adjusts the accelerator pedal opening according to the voltage signal obtained in step S2.

[0048] In some embodiments, in the above step S3, after locking the vehicle, the following steps may be further included: The vehicle terminal sends a message indicating successful vehicle locking to the vehicle remote service provider.

[0049] Specifically, the vehicle terminal sends a lock success message to the remote service provider via an encrypted wireless communication protocol. This message contains the vehicle's unique identifier, a lock timestamp, and status data confirming the vehicle's lock. Upon receiving the lock success message, the remote service provider verifies and decrypts it to ensure its authenticity.

[0050] Second, please refer to Figure 2 , Figure 2 This is a structural diagram of a remote vehicle locking device according to an embodiment of the present application. The remote vehicle locking device provided in this embodiment includes a command receiving module, a conversion module, and a vehicle locking module.

[0051] The command receiving module is used for the vehicle terminal to receive the vehicle locking command issued by the automobile remote service provider.

[0052] The conversion module is used for the vehicle terminal to convert the set opening of the accelerator pedal into a voltage signal.

[0053] The vehicle locking module is used to adjust the opening of the accelerator pedal based on the voltage signal so that the opening of the accelerator pedal is consistent with the set opening of the accelerator pedal, while shielding the input signal of the mechanical accelerator pedal to lock the vehicle.

[0054] In this embodiment, a command receiving module receives a vehicle lock command from a remote vehicle service provider. The conversion module then converts the accelerator pedal's set position in the lock command into a voltage signal. Based on the voltage signal, the vehicle locking module adjusts the accelerator pedal's position to align with the set position. This indirectly controls the vehicle engine by controlling the accelerator pedal's position, while simultaneously shielding the mechanical accelerator pedal's input signal, preventing the driver from affecting vehicle locking through the mechanical accelerator pedal. This achieves vehicle locking, avoiding the various issues associated with directly controlling the engine to lock the vehicle. Furthermore, the module eliminates the need to adapt engine protocols to different engine manufacturers, reducing development costs for vehicle manufacturers.

[0055] In some embodiments, the remote vehicle locking device further includes a verification module.

[0056] The verification module is used to perform security verification on the vehicle locking command based on a preset verification algorithm and secret key.

[0057] In this embodiment, the pre-set verification algorithms include, but are not limited to, cyclic redundancy check (CRC), hash algorithms (MD5 or SHA-256), and exclusive OR (XOR). The key is managed by the vehicle telematics service provider and shared with the vehicle terminal through a secure key distribution mechanism.

[0058] To further improve security, automotive remote service providers should regularly update secret keys and share new secret keys with vehicle terminals to reduce security risks caused by key leakage.

[0059] Regardless of whether the safety check is passed or not, the vehicle terminal will record the relevant information of this safety check, including but not limited to the content of the vehicle locking instruction, the result of the check and the timestamp of this check.

[0060] In a more specific embodiment, please refer to Figure 3 , Figure 3 This is a detailed schematic diagram of the remote vehicle locking device according to an embodiment of the present application. The remote vehicle locking device provided in this embodiment includes a command receiving module, a conversion module, and a vehicle locking module. The command receiving module includes an onboard terminal, the conversion module includes a CAN transceiver and a computing chip, and the vehicle locking module includes a Hall effect sensor. Data is transmitted between the automotive remote service provider platform, the onboard terminal, the CAN transceiver, and the computing chip based on a proprietary protocol.

[0061] The on-board terminal is used to implement private protocol interaction with the automobile remote service provider platform. It is also used to receive instructions issued by the automobile remote service provider to activate the car locking function, terminate the activation of the car locking function, start locking the car, end locking the car, set the accelerator pedal opening and set the car locking time. After the on-board terminal converts the instructions into CAN data messages, it will send the CAN data messages to the CAN transceiver.

[0062] The CAN transceiver is used to receive CAN data messages transmitted by the vehicle terminal and transmit the CAN data messages to the computing chip.

[0063] The computing chip is used to execute commands such as activating and deactivating the vehicle locking function, starting and ending vehicle locking, setting the accelerator pedal opening, and setting the vehicle locking duration. It is also used to convert the accelerator pedal opening command into a voltage signal and transmit it to the Hall effect sensor.

[0064] The Hall sensor is used to feed back the voltage signal transmitted by the computing chip to the accelerator pedal through a hard line, thereby adjusting the opening of the accelerator pedal so that the opening of the accelerator pedal is consistent with the set opening of the accelerator pedal.

[0065] The accelerator pedal is a mechanical component in a real vehicle that controls the accelerator pedal opening. By controlling the accelerator pedal opening, the engine's fuel injection amount is controlled, and then the engine's torque output is controlled.

[0066] Traditional engine locking technology is often limited to specific engine models or brands, which to some extent restricts OEMs' freedom in developing locking functions. This device eliminates this reliance on engine locking technology and uses a simpler control chain to address the complex protocol development requirements of various OEMs. This reduces control links and improves control efficiency, making the locking device more stable and reliable, significantly reducing the degree to which OEMs are constrained by engine manufacturers. Furthermore, by controlling the vehicle's engine operation based on the accelerator pedal position, it can be adapted to various OEM models, significantly improving market coverage and dealer satisfaction.
