As shown in fig. 2, in an exemplary embodiment, a remote diagnosis method for a vehicle fault at least includes steps S210 to S230, which are described in detail as follows:
s210, original fault information and scene information of a vehicle at a current time point are obtained;
s220, performing fault judgment according to the original fault information and the scene information to obtain a current fault result;
and S230, the current fault result is sent to a remote target object, and remote diagnosis of the vehicle is completed.
Fig. 3 is a schematic functional architecture diagram shown in an exemplary embodiment of the present application, where a remote diagnosis method for a vehicle fault is based on an SOA (Service-oriented architecture), and specifically includes an IO abstraction layer, a basic Service layer, an atomic Service layer, a system and scenario application Service layer, and a DTC (diagnostic tree) information Service module;
in step S210, the IO abstraction layer and the basic service layer collect original fault information, where the IO abstraction layer and the basic service layer include:
a) The local hardware switch IO abstract module is used for collecting fault information of switch type interfaces, and each switch IO interface needs to independently provide a corresponding interface to collect the fault information;
b) The local hardware driving IO abstract module is used for collecting fault information of a driving type interface, including output open-circuit faults, short-circuit to ground, short-circuit to power supply, overcurrent faults and the like;
c) The local complex drive feedback IO abstract module is used for collecting fault information of various complex drive type interfaces, and comprises motor drive faults (motor locked rotor faults, motor idle faults, motor over-temperature faults and the like), sensor faults and the like.
d) The CAN (controller area network) bus signal service conversion basic service module is used for collecting various fault information of CAN communication, including CAN information state faults, CAN power saving loss faults, CAN information CRC check faults and the like.
e) The Local Interconnect Network (LIN) bus signal service conversion basic service module is used for collecting various fault detections of LIN communication, including LIN information state faults, LIN node loss faults, LIN information CRC check faults and the like.
In step S220, fault judgment is performed through the atomic service layer, the enhanced service layer, the system and the scene application service layer; specifically, the atomic service layer records according to original fault information collected by the IO abstract layer and the basic service layer, for example, motor over-temperature faults are collected. The enhanced service layer is used for judging the priority of the scene of the original fault information, for example, the priority of the scene information output by the power state and the local motor is highest in a plurality of scenes when the motor is in an over-temperature fault, so that the enhanced service layer selects the two scenes of the power state and the local motor to judge the over-temperature fault of the motor.
Specifically, when the current time point includes a plurality of scenario information, performing fault determination according to the original fault information and the scenario information, and obtaining the current fault result may include steps S221 to S223, which are described in detail below:
s221, acquiring priorities of the plurality of scene information;
s222, extracting scene information with highest priority from the plurality of scene information;
s223, performing fault judgment according to the original fault information and the scene information with the highest priority, and obtaining a current fault result.
And selecting a plurality of scenes according to the priority to obtain the scene most suitable for analyzing by combining the original fault information.
The system and scene application service layer is used for analyzing the fault information in combination with the scene to obtain the current fault result;
in an embodiment of the present invention, the process of performing the fault determination according to the original fault information and the scenario information with the highest priority to obtain the current fault result may include steps S224 to S225, which are described in detail below:
s224, comparing the original fault information, the scene information with the highest priority and a pre-established information combination, wherein the information combination comprises target fault information and target scene information;
s225, when the original fault information, the scene information with the highest priority and the information combination are consistent, judging that the vehicle has a fault, and taking a fault result corresponding to the information combination as a current fault result.
In this embodiment, by analyzing the scenario information and the original fault information when the fault occurs in advance, combining the scenario information corresponding to multiple faults with the original fault information to obtain a combination of the scenario information corresponding to multiple fault results and the original fault information, and comparing the current original fault information and the scenario information with the highest priority with the information combination, if the current original fault information and the scenario information with the highest priority match with the information combination, correspondingly outputting a fault result of the information combination. For example, the information combination includes: the scene information, the power state ON file and the local motor output are effective, and the original fault information, the motor over-temperature fault. And when the current time point acquires the motor over-temperature fault, and the scene accords with the power state ON gear and the local motor output is effective, judging that the fault result is the motor over-temperature fault.
In step S230, a corresponding process is implemented through the DTC information service module, which needs to monitor the DTC fault diagnosis and judgment status notification of the atomic service, the enhanced service, the system service, and the scene application service, update the status of the current fault DTC, and call the DTC storage basic service to store the DTC fault status locally. Long-term storage allows historical fault information to be stored locally.
Since the current fault result may be subject to external tampering, such as tampering by the UDS (UnifiedDiagnostic Services, same diagnostic service) protocol, the DTC information service module may further obtain a local DTC fault state (historical fault information) and compare the current fault result with the historical fault information, and specifically, the process after obtaining the current fault result may further include steps S231 to S234, which are described in detail below:
s231, comparing the current fault result with locally pre-stored historical fault information;
s232, when the current fault result is inconsistent with the historical fault information, acquiring first original fault information and first scene information again;
s233, performing fault judgment according to the first original fault information and the first scene information to obtain a first fault result;
and S234, replacing original fault information and current fault results stored locally according to the first original fault information and the first fault result.
In an embodiment of the invention, the DTC information service module further provides a remote service interface for notifying the remote client of the current fault result, and simultaneously provides a fault query interface for the remote client to facilitate real-time query; in addition, after the remote client issues the DTC clearing request (fault information clearing instruction), the remote client may further provide a clearing service DTC fault cache state and call the DTC storage basic service to update the local DTC fault storage state, and specifically, the process after sending the current fault result to the remote target object may further include steps S235 to S238, which are described in detail below:
s235, when a fault information clearing instruction from the target object is received, clearing the current fault result according to the fault information clearing instruction; the fault information clearing instruction is generated based on the current fault result;
s236, after clearing the current fault result according to the fault information clearing instruction, re-acquiring second original fault information and second scene information;
s237, performing fault judgment according to the second original fault information and the second scene information to obtain a second fault result;
s238, replacing original fault information and current fault results stored locally according to the second original fault information and the second fault result.
In this embodiment, it should be noted that, setting and clearing of the DTC storage infrastructure fault can only change the state of the current DTC fault, and the fault state of the history cannot be cleared.
