It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In one embodiment, as shown in fig. 1, a method for handling a failure of an electric tailgate of an automobile is provided, which is described by taking the method as an example of being applied to a terminal, where the terminal may be a mobile terminal, such as a mobile phone, a tablet computer, a smart wearable device, an automobile-specific tester, and the like. The fault processing method of the electric tail gate of the automobile comprises the following steps:

s100: and acquiring real-time motion state data and fault diagnosis information in the electric operation process of the electric tail gate.

The electric operation of the electric tail gate comprises electric opening and electric closing, and is the operation of the electric tail gate in a motion state; the real-time motion state data in the electric operation process of the electric tail gate refers to the real-time motion state data in the electric door opening process or the electric door closing process of the electric tail gate. And acquiring real-time motion state data and fault diagnosis information in the electric operation process of the electric tail gate, so as to acquire the data of the electric tail gate in the motion state.

The real-time motion state data may include one or more of a rotation speed of the strut motor, a steering direction of the strut motor, a position of the self-priming latch, a state signal of the car tail gate lock, an unlocking signal of the car tail gate, an ECU (Electronic control unit) working voltage, an ambient temperature, a current of the strut motor, a current of the self-priming latch, a number of operations of the electric tail gate, a number of electric failures of the electric tail gate, a running state of the tail gate, a position height, a target rotation speed at the current position height, and a motion state of the self-priming latch. The fault diagnosis information comprises information representing the fault of the electric tail gate and information representing the non-fault of the electric tail gate; the information indicating the power tailgate failure may specifically be information indicating the type of failure. Specifically, the terminal may receive real-time motion state data and fault diagnosis information during the electric operation of the electric tailgate, which are sent by the external device, for example, the real-time motion state data and fault diagnosis information sent by the ECU of the electric tailgate.

S110: and if the fault diagnosis information is information representing the fault of the electric tail gate, acquiring the current system parameters of the ECU of the electric tail gate.

And the terminal carries out fault analysis through the fault diagnosis information, and if the fault diagnosis information is information representing the fault of the electric tail gate, the fault of the electric tail gate is represented. The ECU of the electric tailgate is a device that controls the operation of the electric tailgate. The current system parameters of the ECU of the electric tail gate refer to the current system parameters of the ECU of the electric tail gate. The system parameters comprise one or more of the opening height of the electric tail gate, the opening and closing speed, the opening and closing acceleration and the opening and closing anti-clamping force; that is, the current system parameters may include one type or more types of system parameters.

S130: and obtaining the system parameters to be updated according to the fault diagnosis information and the current system parameters.

Specifically, the terminal may adjust one or more system parameters in the current system parameters according to the fault diagnosis information, and use the adjusted and adjusted system parameters as the system parameters to be updated, or use a parameter set of the adjusted system parameters and the unadjusted system parameters as the system parameters to be updated.

S150: and if the system parameters to be updated are within the corresponding pre-stored system parameter allowable range, sending the system parameters to be updated to the ECU of the electric tailgate, and updating the current system parameters by the ECU of the electric tailgate according to the system parameters to be updated.

After the ECU of the electric tail gate receives the system parameters to be updated, the system parameters to be updated can be adopted to replace the current system parameters of the corresponding type, so that the current system parameters are updated, and therefore fault processing is carried out. Specifically, the terminal may generate a system parameter update instruction according to the system parameter to be updated, and send the system parameter update instruction to the ECU of the electric tailgate, and the ECU of the electric tailgate analyzes the system parameter update instruction to obtain the system parameter to be updated, and updates the current system parameter.

The system parameter allowable range is a data range corresponding to the minimum value of the system parameter allowed by normal work and the maximum normal value of the system parameter. Specifically, one type of system parameter corresponds to one system parameter allowable range. If the adjusted current system parameters comprise various types of system parameters, the system parameters to be updated also comprise various types of system parameters; correspondingly, step S150 sends the system parameters to be updated to the ECU of the electric tailgate when all the system parameters to be updated are within the corresponding system parameter allowable ranges, respectively. Specifically, the allowable range of the system parameter corresponding to each type of system parameter may be fixed, or may be changed according to the vehicle type, for example, the terminal may receive a vehicle model input by a user or sent by an ECU of the electric tailgate, and look up the allowable range of the system parameter corresponding to each type of system parameter under the vehicle model from a pre-stored relationship data table according to the vehicle model.

S170: and if the system parameters to be updated are not in the corresponding pre-stored system parameter allowable range, sending the real-time motion state data, the fault diagnosis information and the current system parameters to the server.

Specifically, if the system parameters to be updated include multiple types of system parameters, step S170 sends the real-time motion state data, the fault diagnosis information, and the current system parameters to the server when any one of the system parameters to be updated is not within the allowable range of the corresponding system parameter.

Specifically, the terminal may generate a data upload request instruction according to the real-time motion state data, the fault diagnosis information, and the current system parameter, and send the data upload request instruction to the server, and the server receives and analyzes the data upload request instruction to obtain the real-time motion state data, the fault diagnosis information, and the current system parameter.

S190: and receiving fault processing guide information returned by the server according to the real-time motion state data, the fault diagnosis information and the current system parameters, and performing processing operation according to the fault processing guide information.

And the terminal waits for the feedback of the server after sending the real-time motion state data, the fault diagnosis information and the current system parameters to the server. The server can generate fault processing guide information according to the real-time motion state data, the fault diagnosis information and the current system parameters and return the fault processing guide information to the terminal. Wherein the fault handling guidance information is information giving a fault handling decision; and the terminal performs processing operation according to the fault processing guide information so as to perform fault processing.

It is to be understood that the order of execution of the steps may not necessarily be in the order indicated by the arrows in fig. 1. Specifically, the real-time motion state data in the electric operation process of the electric tailgate may be obtained first according to the execution sequence indicated by the arrow in fig. 1, or may be obtained again when the system parameters to be updated are not within the allowable range of the corresponding pre-stored system parameters.

According to the method for processing the fault of the electric tail gate of the automobile, when the fault diagnosis information in the electric operation process of the electric tail gate is the information representing the fault of the electric tail gate, the fault of the electric tail gate is represented, the current system parameter of the ECU of the electric tail gate is obtained at the moment, and the system parameter to be updated is obtained according to the fault diagnosis information and the current system parameter; and then carrying out fault processing according to the system parameters to be updated, specifically, if the system parameters to be updated are within the corresponding pre-stored system parameter allowable range, sending the system parameters to be updated to the ECU of the electric tailgate to enable the ECU of the electric tailgate to update the current system parameters so as to carry out fault processing, otherwise, sending the acquired real-time motion state data, fault diagnosis information and the current system parameters to a server, and carrying out processing operation according to fault processing guide information returned by the server so as to carry out fault processing. Therefore, the real-time motion state data and the fault diagnosis information are obtained for analysis and processing, the fault can be automatically and correspondingly processed, when the electric tail gate has the fault, the field decision of maintenance personnel is not required to be waited, and the labor cost and the time cost of fault processing can be reduced.

In one embodiment, step S100 includes: sending an electric operation instruction to an ECU of the electric tail gate, wherein the electric operation instruction is used for instructing the ECU of the electric tail gate to control the electric tail gate to execute electric operation; sending a state data request instruction to an ECU of the electric tail gate; and receiving and analyzing a response instruction returned by the ECU of the electric tail gate according to the state data request instruction to obtain real-time motion state data and fault diagnosis information in the electric operation process of the electric tail gate.

After receiving an electric operation instruction sent by a terminal, an ECU of the electric tail gate can control the electric tail gate to execute electric operation of electrically opening or closing the door; the ECU of the electric tail gate can acquire real-time motion state data and fault diagnosis information in the electric operation process of the electric tail gate, and returns the real-time motion state data and the fault diagnosis information in the electric operation process of the electric tail gate to the terminal after receiving a state data request instruction sent by the terminal. The electric operation instruction is sent firstly to control the electric tail gate to carry out electric operation, so that data in the electric operation process can be collected and acquired, and the data in the motion state of the electric tail gate can be analyzed and subjected to fault treatment.

Specifically, after the terminal sends the electric operation instruction to the ECU of the electric tailgate, the terminal may wait for the ECU of the electric tailgate to feed back a signal that the electric operation is completed, or wait for a preset duration, and then send the status data request instruction. The preset time length can be preset according to the time required by the ECU of the electric tail gate to respond to the electric operation instruction to control the electric tail gate to complete the electric operation. Therefore, the reserved time for the electric operation of the electric tail gate can be reserved, and the real-time motion state data and the fault diagnosis information in the electric operation process of the electric tail gate can be accurately acquired after the terminal sends the state data request instruction.

In one implementation, step S110 may include: judging whether the fault diagnosis information is information representing the fault of the electric tail gate; if so, sending a system parameter request instruction to the ECU of the electric tail gate, and waiting for a response instruction of the ECU of the electric tail gate; analyzing a response instruction of the ECU of the electric tail gate to obtain the current system parameters of the ECU of the electric tail gate; if not, namely the fault diagnosis information is information representing that the electric tailgate is not in fault, the processing flow of the automobile electric tailgate fault processing method is exited.

In one embodiment, the current system parameters include multiple types of system parameters, wherein a type of a system parameter is a data type. The step S130 includes: determining the fault type according to the fault diagnosis information; and adjusting the preset type system parameters corresponding to the fault type in the current system parameters according to the adjustment mode corresponding to the fault type to obtain the system parameters to be updated.

The information indicating the electric tail gate fault can be specifically information indicating a fault type, and the terminal reads and identifies fault diagnosis information to determine the fault type. Wherein the fault types include: a short circuit of the left/right electric stay rod motor, a locked rotation of the left/right electric stay rod motor, a Hall failure of the left/right electric stay rod, a Hall reversal of the left/right electric stay rod, a short circuit of the self-priming lock motor, a locked rotation of the self-priming lock motor, a failure of the self-priming lock position switch, and the like.

Specifically, the fault type and the adjustment mode may be in a one-to-one relationship or a many-to-one relationship, that is, one fault type may correspond to one adjustment mode, or multiple different fault types may correspond to the same adjustment mode. Specifically, the adjustment manner may be an increase value or a decrease value. The preset types of system parameters corresponding to different fault types can be the same type or different types; that is, for different faults, the same type of system parameters in the current system parameters may be adjusted, or different types of system parameters may be adjusted. The current system parameters are correspondingly adjusted through the terminal according to the fault types, and the parameter adjusting effect is good.

In one embodiment, the fault handling guidance information includes decision instructions suggesting upgrading of software and decision instructions suggesting replacement of parts. Step S190 includes: if the fault processing guide information is a decision instruction for recommending upgrading software, analyzing the decision instruction for recommending upgrading software to obtain a storage path of ECU software upgrading data; reading ECU software upgrading data according to the storage path; and sending the ECU software upgrading data to the ECU of the electric tail gate, and carrying out software upgrading on the ECU of the electric tail gate according to the ECU software upgrading data.

The ECU software upgrading data is obtained according to the decision instruction of the proposed upgrading software and is sent to the ECU of the electric tail gate, so that the ECU of the electric tail gate carries out software upgrading, and faults are eliminated through software upgrading. Specifically, the terminal can be directly communicated with the ECU of the electric tail gate, and the terminal sends the ECU software upgrading data to the ECU of the electric tail gate through a communication network; the terminal may also relay data communicated with the ECU of the power tailgate through a communication device. For example, taking communication equipment as a wireless gateway downloader as an example, after the terminal acquires the ECU software upgrading data, the terminal may generate a file transmission instruction according to the ECU software upgrading data, send the file transmission instruction to the wireless gateway downloader, and wait for a response instruction of the wireless gateway downloader; the wireless gateway downloader forwards ECU software upgrading data to an ECU of the electric tail gate, acquires the state of whether the ECU of the electric tail gate finishes software updating, and feeds a response instruction back to the terminal according to the acquired state; the terminal analyzes the response instruction of the wireless gateway downloader to obtain the state whether the ECU of the electric tailgate completes software updating, if the ECU software upgrading data transmission is completed and the ECU of the electric tailgate completes software updating, the step S100 is returned, the steps are repeated, and if the ECU does not complete software updating, the terminal continues to wait for the response instruction of the wireless gateway downloader.

In one embodiment, step S190 further comprises: and if the fault processing guide information is a decision instruction for recommending the replacement of the parts, controlling the reminding device to output reminding information for replacing the parts.

The reminding device can be a display screen, a voice broadcast device, an alarm and the like; the reminding information can be character information, voice information, acousto-optic information and the like. When a decision instruction for recommending the replacement of the parts is received, the reminding device is controlled to output reminding information so as to inform a user of carrying out fault removal by replacing the parts.

It should be understood that, although the steps in the flowchart of fig. 1 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 1 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
