Description

Technical Field

[0001] The present invention relates to the technical field of automobile start control, and in particular to a control method and system for emergency start of a vehicle. Background Art

[0002] For existing vehicles equipped with a PEPS module, users only need to carry their key to unlock and start the vehicle, without having to manipulate the key or insert it into the ignition lock. This functionality requires a functioning PEPS antenna system and a valid key. If the antenna malfunctions or the key is removed from the vehicle by another passenger, the vehicle's starting function will be restricted. Existing vehicles use an additional identity authentication system to control vehicle start, such as fingerprint and facial recognition. However, this is expensive and increases vehicle production costs. Therefore, providing a convenient vehicle emergency start control system is crucial. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to more clearly illustrate the specific embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments.

[0031] Figure 1 This is a schematic diagram of a vehicle emergency start control method provided by the present invention.

[0032] Figure 2 This is a schematic diagram of a vehicle emergency start control system provided by the present invention. DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings and implementation methods.

[0034] In response to the problem that current vehicles cannot be emergency started, the present invention provides a control method and system for vehicle emergency start, which solves the problem that existing vehicles cannot be emergency started when the PEPS antenna fails or the key is not around the vehicle, and can improve the convenience and safety of vehicle use.

[0035] like Figure 1 As shown, a control method for emergency starting of a vehicle includes:

[0036] S1: Configure the PEPS control module and T-BOX on the vehicle, and perform authentication and encryption on the PEPS control module and T-BOX.

[0037] S2: Set the T-BOX to communicate with the Internet of Vehicles platform through the Internet of Vehicles, and enable the user's smart terminal to communicate with the Internet of Vehicles platform through the mobile network.

[0038] S3: When the PEPS key cannot be recognized or the user forgets to bring it, a remote unlocking instruction is sent through the smart terminal.

[0039] S4: After receiving the remote unlocking instruction, the T-BOX sends a vehicle unlocking message via the CAN bus, and the PEPS control module unlocks the vehicle according to the vehicle unlocking message.

[0040] S5: After the user enters the vehicle and the smart terminal sends an emergency start command, the T-BOX sends an emergency start message according to the emergency start command, and the PEPS control module enters the emergency start mode according to the emergency start message to start the vehicle.

[0041] Specifically, if the PEPS key is unrecognizable or forgotten, a remote unlock command is sent via an app running on a remote smart terminal. The connected vehicle platform then transmits the vehicle unlock command to the T-BOX via the connected vehicle network, allowing the driver to enter the vehicle. After the driver enters the vehicle, an emergency start message is sent via the smart terminal, and then via the T-BOX, causing the PEPS control module in the vehicle to enter emergency start mode, thereby starting the vehicle. The T-BOX communicates with the smart terminal and the PEPS control module, converting remote network signals into the vehicle's CAN bus signals. It also performs authentication and encryption between the T-BOX and the PEPS, ensuring secure entry into emergency mode. The authentication algorithm, which uses AES128, serves as the primary security barrier. The PEPS control module comprises a PEPS controller, a keyless entry (PE) control unit, and a push-to-start (PS) control unit. The PEPS control module enables IGN-ACC-OFF switching and keyless entry, initiates a start request to start the vehicle, and can also disconnect IGN power to shut down the vehicle. This method can solve the problem that existing vehicles cannot be emergency started when the PEPS antenna fails or the key is not around the vehicle, and can improve the convenience and safety of vehicle use.

[0042] The method further includes: after the T-BOX receives the remote unlocking command or the emergency start command, the T-BOX performs authentication verification with the PEPS control module, and after the authentication is passed, determines whether emergency module startup success information or one-key start success information fed back by the PEPS control module is received.

[0043] The method also includes: after receiving the emergency module startup success information or the one-key startup success information, the T-BOX sends startup feedback information to the Internet of Vehicles platform through the Internet of Vehicles, and the Internet of Vehicles platform sends the vehicle startup status to the smart terminal according to the startup feedback information.

[0044] Specifically, when the driver enters the vehicle, the emergency start mode command is issued through the smart terminal. After receiving the command, the vehicle's T-BOX authenticates and encrypts it with the PEPS control module. After the authentication is passed, the PEPS control module feedbacks that the emergency mode is successfully started. The PEPS control module feedbacks that the one-button start ignition switch indication mode is successful, and at the same time feedbacks this status signal to the T-BOX through the CAN bus. The T-BOX then sends it to the car networking platform through the car networking network, and then feedback to the user's smart terminal through the mobile communication network.

[0045] The method further includes: the PEPS control module is provided with an operation password verification mechanism. After the vehicle enters the emergency start mode, the PEPS control module determines whether the vehicle's operation password verification is successful based on the sequence of operations performed by the driver. If not, the PEPS control module sends a password verification failure message to the T-BOX.

[0046] The method further includes: after the vehicle's operation password is successfully verified, the PEPS control module receives status messages of the brake pedal, gear position, handbrake, ignition switch, turn signal and wiper switch through the CAN bus, and determines whether the vehicle is in a fault state based on the status messages. If so, a vehicle fault message is sent to the T-BOX.

[0047] Furthermore, the PEPS control module is provided with an operation password verification mechanism, including: within a set time after the brake pedal is depressed, sequentially operating the front wiper, and toggling the left turn signal and the right turn signal a set number of times.

[0048] In one embodiment, when the vehicle enters emergency start mode, the driver first checks and confirms the vehicle status (gear is in neutral or P gear, or the mechanical parking brake is applied, etc.), and then performs a sequence operation password verification: after pressing the brake pedal; within a set time, the first toggle switches the front wiper twice, the second toggle switches the left turn signal twice, and the third toggle switches the right turn signal twice. After the sequence is entered correctly, the PEPS control module feedbacks that the vehicle-side password verification is successful, and the PEPS control one-touch start ignition switch indicator mode is successful, which can be indicated by a flashing green indicator light. At the same time, this status signal is fed back to the T-BOX via the CAN bus, and then fed back to the user's smart terminal.

[0049] The method further includes: during the operation password verification, the PEPS control module determines that timeout or operation sequence error is a failure in the operation password verification, and the PEPS control module exits the emergency startup program.

[0050] In practice, after a vehicle's emergency start authorization is successfully granted, a password must be entered within a specific timeframe (e.g., 120 seconds). If the password times out or the password is incorrect, PEPS will exit the emergency start state. During the password entry process, specific operations must be completed within a specific timeframe. If the operation sequence is incorrect or the time window times out, PEPS will deem the password input incorrect and directly exit the emergency start state.

[0051] It can be seen that the present invention provides a control method for emergency starting of a vehicle, which sends a remote unlocking command and / or emergency starting command to the T-BOX in the vehicle through an intelligent terminal, remotely unlocks the vehicle and enables the PEPS control module to control the vehicle start, thereby solving the problem that the vehicle cannot be emergency started when the PEPS antenna fails or the key is not around the vehicle, and can improve the convenience and safety of vehicle use.

[0052] Accordingly, the present invention also provides a vehicle emergency start control system, using the above control method, the system includes: a PEPS control module, a T-BOX, a vehicle networking platform and an intelligent terminal;

[0053] The vehicle is equipped with a PEPS control module and a T-BOX, the PEPS control module and the T-BOX are connected via a CAN bus, and authentication and encryption are performed on the PEPS control module and the T-BOX;

[0054] The T-BOX is connected to the Internet of Vehicles platform through the Internet of Vehicles, and the Internet of Vehicles platform is connected to the user's smart terminal through the mobile network. The smart terminal is used to send remote unlocking instructions and / or emergency start instructions to the vehicle, so that the vehicle can be remotely unlocked and / or emergency started accordingly.

[0055] Preferably, the smart terminal includes at least any one of the following: a smart phone, a tablet computer and a smart wearable device.

[0056] Preferably, it further includes: an engine controller;

[0057] The PEPS control module is communicatively connected to the engine controller via a CAN bus. The PEPS control module receives status messages of the brake pedal, gear position, parking brake, ignition switch, turn signal, and wiper switch from the engine controller, and determines whether the vehicle is in a fault state based on the status messages. If so, the PEPS control module sends a vehicle fault message to the T-BOX.

[0058] It can be seen that the present invention provides a vehicle emergency start control system, which sends a remote unlocking command and / or emergency start command to the T-BOX in the vehicle through the intelligent terminal, remotely unlocks the vehicle and enables the PEPS control module to control the vehicle start, thereby solving the problem that the existing vehicle cannot be emergency started when the PEPS antenna fails or the key is not around the vehicle, and can improve the convenience and safety of vehicle use.
