Description

Technical Field

[0001] The present application relates to the technical field of traffic control systems, and in particular to a remote vehicle search method, controller, system and storage medium. Background Art

[0002] Remote vehicle locating technology usually relies on GPS positioning systems and intelligent vehicle communication systems. When a vehicle is equipped with a GPS locator, the owner can track the vehicle's location in real time through a mobile phone application or other remote device. In addition, some systems also use Bluetooth signals to communicate with mobile phones to help car owners quickly locate their vehicles in complex environments such as large parking lots or shopping malls.

[0003] The combination of remote vehicle search technology and body control module (BCM) provides modern car users with a more convenient and intelligent vehicle search experience. BCM receives remote vehicle search signals from car owners and performs authentication and information feedback. If BCM fails, remote vehicle search will fail.

[0004] Therefore, there is an urgent need for a remote vehicle search solution in the event of BCM failure. Summary of the invention

[0005] The purpose of the present application is to provide a remote vehicle search method, controller, system and storage medium to achieve remote vehicle search in the event of BCM failure.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions: In a first aspect, the present application provides a remote vehicle search method, comprising: Receiving a fault message of a vehicle body controller sent by an intelligent vehicle-mounted terminal, wherein the fault information is sent by the intelligent vehicle-mounted terminal to a target controller when the intelligent vehicle-mounted terminal does not receive a response from the vehicle body controller to a remote authentication request message; In response to the fault message, controlling the vehicle body controller to restart; If the vehicle body controller still does not respond to the remote authentication request message after restarting, the vehicle body controller controls the components of the vehicle to perform a first designated action to prompt the user of the location of the vehicle.

[0007] In a second aspect, the present application provides a remote vehicle search system, comprising: The intelligent vehicle terminal sends a fault message of the body controller to the target controller when not receiving a response from the body controller to the remote authentication request message; The target controller controls the vehicle body controller to restart in response to the fault message; If the vehicle body controller still does not respond to the remote authentication request message after restarting, the target controller controls the vehicle components through the vehicle body controller to perform a first designated action to prompt the user of the vehicle's location.

[0008] In a third aspect, the present application provides a controller, comprising: at least one processor, and a memory communicatively coupled to at least one of the processors; The memory stores instructions that can be executed by at least one of the processors, and the instructions are executed by at least one of the processors so that at least one of the processors can execute any of the remote vehicle search methods.

[0009] In a fourth aspect, the present application provides a computer-readable storage medium having computer instructions stored thereon, wherein the computer instructions are used to enable the computer to execute any remote vehicle search method.

[0010] Compared with the prior art, the beneficial effects of this application are: The intelligent vehicle terminal in the present application sends a fault message of the body controller to the target controller when it does not receive a response from the body controller to the remote authentication request message, thereby locating the fault of the body controller in the remote vehicle search scenario; then, the controller controls the body controller to restart in order to restore the remote vehicle search function of the body controller. If the body controller still does not respond to the remote authentication request message after restarting, the vehicle components are directly controlled by the body controller to perform the first specified action to trigger the vehicle search operation. It can be seen that when the body controller cannot respond to the remote authentication request message, the present application can still successfully achieve remote vehicle search by restarting and directly controlling the components to perform actions by bypassing the authentication operation.

DETAILED DESCRIPTION

[0013] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0014] The embodiment of the present application provides a remote vehicle search method, which is applicable to the scenario of remote vehicle search through a user's remote terminal. In order to facilitate the description of the solution provided by the present embodiment, the remote vehicle search process is first introduced when the BCM is not invalid (ie, responds normally).

[0015] Figure 1 Schematic diagram of a remote car search scenario provided by an embodiment of the present application. Figure 1 When the user needs to find the car remotely, the remote car search function is turned on on the application of the user terminal, and the user terminal sends a remote car search instruction to the Telematics Service Provider (TSP) platform. The remote car search instruction includes the vehicle's ID. The TSP platform forwards the remote car search instruction to the intelligent vehicle terminal (T-BOX) of the vehicle that matches the ID. After receiving the remote car search instruction, the T-BOX wakes up the vehicle CAN network and sends a remote authentication request message (assuming there are 3 frames) to the BCM. If the BCM is not invalid, the BCM responds to the remote authentication request message and feeds back one of the remote authentication request messages to the T-BOX. Then the T-BOX sends the authentication status and authentication key to the BCM. The BCM performs anti-theft authentication based on the authentication status and authentication key. If the anti-theft authentication passes, the BCM's car search function is triggered. At the same time, the BCM feeds back a successful car search message to the T-BOX. The T-BOX sends the message of successful car search to the user terminal through the TSP platform. If the BCM fails, the BCM cannot respond to the remote authentication request message, and the subsequent remote vehicle search operation cannot be performed.

[0016] In order to solve the above problems, the present application provides a remote vehicle search method. Figure 2 This is a flow chart of a remote vehicle search method provided by this embodiment. The method can be executed by any controller integrated in the vehicle. In order to distinguish it from controllers such as BCM, the execution subject is called the target controller. The method includes the following operations: S110: Receive a fault message of a vehicle body controller sent by an intelligent vehicle-mounted terminal.

[0017] After receiving the remote vehicle search command sent by the TSP platform, the T-BOX sends a remote authentication request message to the BCM. If the BCM does not respond to the remote authentication request message, the T-BOX sends a fault message to the target controller if it does not receive a response from the body controller to the remote authentication request message.

[0018] Optionally, the target controller may be a controller on any vehicle, such as a gateway controller.

[0019] As the data exchange center of the vehicle network, the gateway controller can route data of different network protocols (such as CAN, LIN, MOST, FlexRay, Ethernet, etc.) in different networks. This means that data from different networks can be exchanged and transmitted under the coordination of the gateway controller, realizing the interconnection of information within the vehicle. The gateway controller is usually connected to the interface of the vehicle diagnostic system and is responsible for forwarding and controlling the diagnostic messages of the vehicle. This helps facilitate vehicle maintenance and fault diagnosis. At the same time, the gateway controller also has high information security, which can resist potential risks to the in-vehicle network from the outside world and protect the security of the vehicle's internal data.

[0020] S120: In response to the fault message, control the vehicle body controller to restart.

[0021] After receiving the fault message, the target controller confirms that the BCM remote authentication function is lost, and then sends a restart instruction to the BCM. The BCM restarts according to the restart instruction.

[0022] When a BCM needs to be restarted, it is usually due to a software failure, firmware update, or configuration change. The following is an example BCM restart process, but please note that different manufacturers' BCMs may have different operation methods: 1. Backup configuration: Before performing any restart operation, it is recommended to back up the current settings and configuration files of the BCM. This ensures that you can quickly restore to the previous state in case of problems.

[0023] 2. Check BCM status: Check the current working status of BCM through the web interface, command line tool, or other management tools to confirm whether a restart is really required.

[0024] 3. Notify relevant personnel: If BCM manages important server resources, relevant operation and maintenance personnel or stakeholders should be notified before restarting to avoid unnecessary impacts caused by sudden service interruptions.

[0025] 4. Planned restart time: Try to restart during off-peak hours to reduce the impact on business.

[0026] 5. Perform a reboot: Log in to the BCM's web management interface, find the restart function under the system management or maintenance option, and click Restart. If command line operations are supported, you can log in to the BCM through SSH and use the corresponding command, such as ipmitool mc resetcold, to restart the BCM. In rare cases, if none of the above methods are feasible, you may need to physically access the server and restart the BCM by powering it off and then back on.

[0027] 6. Wait for the restart to complete: After the BCM restarts, it may take some time to initialize and restore all services. During this time, the BCM may not be able to respond to management requests.

[0028] 7. Verify that the restart is successful: After the restart is complete, log in to the BCM management interface or use the command line tool to check whether the BCM is running normally, whether all services have been started, and whether the configuration is correct.

[0029] 8. Record the restart process: Recording the time and reason for the restart, as well as the problems encountered and solutions during the process, will be very helpful for future maintenance and troubleshooting.

[0030] S130: If the vehicle body controller still does not respond to the remote authentication request message after restarting, control the vehicle components through the vehicle body controller to perform a first designated action to prompt the user of the vehicle's location.

[0031] For example, after the BCM restarts, the target controller sends a notification to the T-BOX to restart the BCM; the T-BOX sends a remote authentication request message to the BCM again. If the BCM function is restored, it will respond to the remote authentication request message; if the BCM function is still lost, it will not respond to the remote authentication request message. Regardless of whether the BCM responds or not, the T-BOX will send a feedback message to the target controller to indicate whether the BCM responds to the remote authentication request message.

[0032] After receiving the feedback message, the target controller determines whether the BCM responds to the remote authentication request message after restarting according to the feedback message. If the BCM responds to the remote authentication request message after restarting, the operation is terminated, and the remote vehicle search operation is performed through the interaction between the T-BOX and the BCM. If the BCM still does not respond to the remote authentication request message after restarting, the target controller will control the vehicle components through the BCM to perform the first specified action.

[0033] Optionally, the vehicle components include but are not limited to lights and horns. The purpose of the first designated action is to enable the remote user to see, for example, the horn sounds, and the left and right turn signals flash, etc., to remind the user of the vehicle body position. The vehicle components and the first designated action can be defined according to the vehicle configuration and user settings.

[0034] According to the vehicle's hardware and software architecture, components such as lights and horns are driven and controlled by the BCM, so the target controller needs to send an action instruction to the microcontroller unit (MCU) of the BCM. The microcontroller controls the vehicle's components to perform a first specified action in response to the action instruction.

[0035] The intelligent vehicle terminal in the present application sends a fault message of the body controller to the target controller when it does not receive a response from the body controller to the remote authentication request message, thereby locating the fault of the body controller in the remote vehicle search scenario; then, the controller controls the body controller to restart in order to restore the remote vehicle search function of the body controller. If the body controller still does not respond to the remote authentication request message after restarting, the vehicle components are directly controlled by the body controller to perform the first specified action to trigger the vehicle search operation. It can be seen that when the body controller cannot respond to the remote authentication request message, the present application can still successfully achieve remote vehicle search by restarting and directly controlling the components to perform actions by bypassing the authentication operation.

[0036] Optionally, the target controller responds to the fault message and controls the BCM to restart. If the BCM still does not respond to the remote authentication request message after the restart, the fault information of the functional module in the BCM is determined; the fault information is sent to the remote user terminal through the T-BOX. For example, the target controller sends a fault detection instruction to a device with a fault detection function to detect whether each functional module in the BCM is faulty. This embodiment does not limit the type of device with a fault detection function, which can be an external device or a BCM.

[0037] The fault information at least includes the information of the faulty functional module, the fault type and the repair plan. The target controller sends the fault information to the T-BOX. Then the T-BOX sends the fault information to the remote user terminal through the TSP platform. For example, the fault information "BCM fault, please contact your car manufacturer" is displayed on the user terminal; at the same time, the TBOX notifies the TSP platform and waits for the rescue arrangement of the car manufacturer.

[0038] The present application also provides a remote vehicle search system. Figure 3, including T-BOX, target controller (such as gateway controller) and BCM. The system provided in this embodiment is suitable for the scenario of remote car search through the user's remote terminal. The functions of each component in the system are described in detail below.

[0039] When T-BOX does not receive a response from BCM to the remote authentication request message, it sends a fault message of BCM to the target controller.

[0040] The target controller controls the BCM to restart in response to the fault message; if the BCM still does not respond to the remote authentication request message after restarting, the target controller controls the vehicle components through the BCM to perform a first specified action to prompt the user of the vehicle's location.

[0041] For a more detailed description of the remote vehicle search system, see Figure 4 , now provide a specific implementation method: When the user needs to find the car remotely, the remote user terminal sends a car search instruction to the T-BOX through the TSP platform. After receiving the remote car search instruction, the T-BOX sends a remote authentication request message to the BCM in response to the remote car search instruction. If no response to the remote authentication request message is received from the body controller, a remote authentication request message is sent to the BCM multiple times within the set time. The set time can be customized, for example, 1 minute. The frequency of sending the remote authentication request message can be 1 / 5s. If no response to the remote authentication request message from the BCM is still received, the operation of sending the BCM fault message to the target controller. By sending remote authentication request messages to the BCM multiple times by the T-BOX, the timely transmission and processing of the message can be ensured, giving the BCM sufficient response time to avoid misjudgment.

[0042] After receiving the fault message, the target controller sends a fault detection instruction to the MCU of the BCM. The MCU sends a collection instruction to the electrical parameter collection module. The electrical parameter collection module collects the voltage of each functional module through the voltage sampling circuit. Among them, the functional modules of the BCM include but are not limited to: window control module, lighting control module, electric door lock control module, safety function module, wiper function module, comfort function module, diagnosis and fault reporting module, integrated gateway module and energy consumption control module.

[0043] For example, the window control module controls the lifting of power windows; the lighting control module manages the exterior and interior lighting systems, including functions such as automatic headlights, taillights, turn signals and light dimming. The power door lock control module is used to receive signals from door lock switch requests and control the locking or unlocking of all vehicle doors. The air conditioning system module coordinates the heating, ventilation and air conditioning systems, allowing the driver to adjust the temperature, HVAC mode and fan speed. The safety function module supports keyless entry systems, anti-theft and alarm functions to prevent theft. The wiper control module controls the wiper function, including intermittent wiper control. The comfort function module controls the actuators related to the comfort functions of the car, such as seats, rearview mirrors and electric adjustment, depending on the design of the vehicle. The diagnostic and fault reporting module stores diagnostic data and helps customers identify and troubleshoot problems in the electrical system. The integrated gateway module maintains communication between integrated control units via the vehicle bus system (CAN, LIN or Ethernet). The energy consumption control module optimizes the operating mode of electrical components and reduces power consumption when the components are not in use. This improves the fuel efficiency of traditional vehicles and extends the driving range of electric vehicles.

[0044] In this embodiment, the voltage sampling circuit can accurately measure the voltage value in the circuit and provide real-time voltage data. It can monitor and diagnose faults in the system; it can monitor voltage changes in the circuit, such as voltage fluctuations, overvoltage, undervoltage, etc. This is very critical for protecting the safe operation of circuits and equipment, and measures can be taken in time to avoid damage or failure. The voltage sampling circuit can also convert the collected voltage data into digital signals through the digital-to-analog conversion chip inside or outside the functional module, and transmit it to the host computer, control system and status monitoring module through the interface, so that data storage, analysis and remote monitoring can be realized.

[0045] In this embodiment, the electrical parameter acquisition module sends the electrical parameters of each functional module to the status monitoring module through the voltage sampling circuit. The status monitoring module determines the fault information of the functional module according to the electrical parameters of each functional module. For example, if the voltage of a functional module is 4V and the normal voltage range of the functional module is 5V~10V, the fault information of the functional module is undervoltage, and circuit maintenance is required.

[0046] The status monitoring module returns the fault information to the MCU. The fault information includes, but is not limited to, information about the faulty functional module, the fault type, and the repair plan. After receiving the fault information, the MCU controls the vehicle components to perform a second specified action to prompt the user of the faulty functional module. Optionally, the components here include at least vehicle lights, which are controlled to flash lights of different colors to indicate that the functional module corresponding to the color has failed.

[0047] After receiving the fault information, the MCU also sends the fault information to the target controller. Then the target controller sends the fault information to the remote user terminal through T-BOX. The fault information "BCM fault, please contact your car manufacturer" is displayed on the user terminal; at the same time, TBOX notifies the TSP platform and waits for the car manufacturer's rescue arrangement.

[0048] If the BCM still does not respond to the remote authentication request message after restarting, the target controller sends an action command to the BCM. In response to the action command, the microcontroller controls the horn to beep once (i.e. 360ms ON, 520ms OFF), and the left and right turn signals flash for 15s, with a cycle of 880ms (i.e. 440ms on, 440ms off). The anti-theft authentication signal is always successful within 5 minutes. Even if a remote vehicle search command is received within 5 minutes, the anti-theft authentication process will not be carried out.

[0049] Optionally, in addition to detecting BCM faults by detecting the electrical parameters of the functional modules, you can also use professional automotive diagnostic equipment to connect to the BCM to read fault codes and detect system status. This can provide more detailed and accurate BCM status information, helping to determine which functional modules are faulty.

[0050] If the specific faulty module cannot be determined through electrical parameters and vehicle diagnostic equipment, a functional module in the BCM can be replaced for testing.
