Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a vehicle failure snapshot storage method based on a failure system according to an embodiment of the present invention, where this embodiment is applicable to a case of vehicle failure code storage, and the method may be executed by a vehicle failure snapshot storage device based on a failure system, where the device may be implemented by software and/or hardware, and may be configured in a terminal and/or a server to implement the vehicle failure snapshot storage method based on a failure system according to an embodiment of the present invention.
As shown in fig. 1, the vehicle failure snapshot storage method based on the failure system specifically includes the following steps:
and S110, determining the current vehicle fault based on the vehicle-mounted diagnosis equipment.
The vehicle-mounted diagnosis equipment can monitor the running state of the engine of the current vehicle at any time and diagnose the fault of the current vehicle when the vehicle has the fault, and can diagnose the vehicle when the current vehicle has the fault and detect the vehicle regularly to ensure the normal running of the vehicle. The vehicle fault can be understood as that different types of faults of the vehicle may occur due to various factors in the use process of the vehicle, for example, common vehicle faults may include an engine fault, a brake fault, a network fault, an exhaust system fault, a power steering fault, and the like. The embodiment of the invention does not limit the types of vehicles, and can be cars, buses or buses and the like.
Specifically, during the running of the vehicle, the vehicle-mounted diagnostic device may detect and detect each system of the current vehicle, acquire the state information of the vehicle, and diagnose the state information of the vehicle. When the vehicle is not in fault, the vehicle state information is covered on the last stored information, when the vehicle-mounted diagnostic equipment diagnoses the vehicle fault, the source and the fault type of the fault are judged, and the stored current vehicle state information and the vehicle state information in the preset time period are sent to the monitoring platform. The vehicle state information CAN be acquired in real time through a finished vehicle CAN intelligent network, and the vehicle state information CAN be transmitted through a monitoring host. The monitoring host can store, pack and compress the real-time data of the vehicle state information according to a certain period. The monitoring platform can analyze the data packed and compressed by the monitoring host, and maintenance personnel can see the faults of the current vehicle through the monitoring platform and analyze the faults according to the faults displayed by the monitoring platform.
And S120, identifying the fault category to which the current vehicle fault belongs.
The failure category may be a category set by a vehicle diagnosis engineer in a vehicle failure reference document in advance according to the degree of association between a vehicle failure and each part of the vehicle, and each failure category includes state information of a vehicle part that may cause a certain vehicle failure and does not include state information of a vehicle part that is not related to the failure.
Specifically, during the running process of the vehicle, the vehicle diagnosis device detects the current vehicle and diagnoses whether the current vehicle has a fault, and when the vehicle fault is found, a diagnosis module in the vehicle diagnosis device can classify the fault type of the current vehicle according to a preset rule, wherein the preset rule can be understood as that the vehicle fault and a vehicle system related to the fault are correspondingly set in advance to generate a corresponding relationship. For example, when the exhaust system of the vehicle is malfunctioning, the vehicle diagnosis apparatus may recognize a malfunction category to which the current vehicle malfunction belongs as the exhaust system malfunction, according to a correspondence relationship set in advance.
Optionally, identifying the fault category to which the current vehicle fault belongs includes: the method comprises the steps of obtaining a fault code of a current vehicle fault, and determining a fault type of the current vehicle fault based on a corresponding relation between the fault code and the fault type.
The fault code may be understood as an identifier corresponding to a fault that is analyzed and reflected by an Electronic Control Unit (ECU) in the vehicle when the vehicle has a fault, where the fault code corresponds to the vehicle fault one to one, and the current vehicle fault is easily known by the fault code. For example, P000 may indicate that the current vehicle is not malfunctioning; p0100 may indicate an air flow meter line fault P00107 may indicate that the inlet pressure sensor input voltage is too low; p0108 may indicate that the inlet pressure sensor input voltage is too high; p0109 can indicate that the circuit of the intake temperature sensor is poor or the circuit of the intake pressure sensor is intermittent; p0115 may indicate that the line of the engine water temperature sensor is bad, and the specific corresponding relationship is not illustrated. It can be understood that the vehicle fault and the vehicle fault code correspond to each other according to a preset corresponding relationship, wherein the relationship between the vehicle fault and the vehicle fault code may be a default, or may be set by a vehicle diagnosis engineer according to an actual situation.
Specifically, when the vehicle diagnosis engineer sets the correspondence relationship between the vehicle faults, the correspondence relationship between the fault codes and the fault categories is pre-established according to the degree of association with the vehicle faults, and each fault category may include one or more fault codes. For example, fault category 1 may contain fault codes P0001-P0010, representing the current vehicle's exhaust system fault category; the fault category 2 can contain fault codes P0011-P0020 which represent the fault category of the network system of the current vehicle, and the fault category 3 can contain fault codes P0021-P0030 which represent the fault category of the chassis of the current vehicle; the fault category 4 may include fault codes P0031 to P0040, which represent the fault category of the temperature control system of the current vehicle, and the like, and the specific correspondence between the vehicle fault category and the vehicle fault code may be set by a vehicle diagnosis engineer according to the actual situation, and the specific correspondence is not limited.
After the vehicle is diagnosed by the vehicle diagnosis equipment, the vehicle fault can be displayed in the form of a fault code according to the relationship between the vehicle fault and the vehicle fault code, and then the fault type to which the current vehicle fault belongs can be determined according to the preset corresponding relationship between the vehicle fault type and the vehicle fault code.
S130, determining a corresponding associated fault snapshot category according to the fault category, wherein the associated fault snapshot category is a part of all fault snapshot categories.
The failure snapshot may be understood as that in order to know the actual condition of the vehicle in time when the vehicle failure is checked, the vehicle ECU may record data of vehicle speed information, the rotation speed of the engine, ignition state information, vehicle power battery voltage information, a network bus, and the like of the vehicle according to a time sequence, so as to generate failure snapshot data. The vehicle fault snapshot can be recorded when a fault occurs, and can also be recorded according to the capturing time of the fault snapshot. The failure snapshot category may be understood as a failure snapshot category corresponding to the failure category, which is divided into failure snapshot categories according to the relevance between the failure snapshots and the failure categories.
Specifically, according to the type of the vehicle fault, the vehicle fault is divided into different fault categories, and according to the correlation between the fault snapshot category and the fault category, an associated fault snapshot category corresponding to the fault category is determined, wherein the fault snapshot category associated with each fault category is a partial category of all the fault snapshot categories.
Optionally, the fault category includes at least one of: an intelligent system controller local area network fault, a transmission system hardware fault, a sensor hardware fault, an exhaust system fault, a chassis fault, and a body fault.
Optionally, the associated fault snapshot category corresponding to the local area network fault of the intelligent system controller includes: fault snapshots of an automobile power system, node disconnection fault snapshots and line fault snapshots;
the classes of drive train hardware failure snapshots include: a clutch failure snapshot and a transmission failure snapshot;
the associated fault snapshot categories corresponding to the sensor hardware faults include: an oxygen sensor fault snapshot, a wheel speed sensor fault snapshot, a water temperature sensor fault snapshot or a crankshaft position sensor and a camshaft position sensor;
the associated fault snapshot categories corresponding to the emission system faults include: an ignition system fault snapshot and an oil supply system fault snapshot;
the associated fault snapshot categories corresponding to the chassis faults include: a steering system fault snapshot, a braking system fault snapshot, a power system fault snapshot and a suspension fault snapshot;
the associated fault snapshot category corresponding to the vehicle body fault comprises: the method comprises the following steps of taking a snapshot of a wiper failure fault, a snapshot of a vehicle glass lifter failure fault, a snapshot of a brake lamp failure fault and a snapshot of an in-vehicle air-conditioning cycle imbalance fault.
And S140, correspondingly storing the fault snapshot of the associated fault snapshot category and the fault code of the current vehicle fault.
Specifically, each fault category includes a fault snapshot category associated with the fault category, each fault snapshot category also includes a fault snapshot associated with the fault snapshot category, each fault code may correspond to a group of fault snapshots, the fault snapshots of the current vehicle fault and the fault codes are stored correspondingly, so that the current vehicle fault is directly judged according to the fault codes, and the fault snapshots corresponding to the fault codes may be called correspondingly by calling the fault codes. The failure snapshot categories associated with the failure categories can be one or more, and the failure snapshots associated with the failure snapshot categories can be one or more.
Optionally, if the number of the current vehicle faults is more than two and the fault categories to which the current vehicle faults belong are more than two, the correspondingly storing the fault snapshots of the associated fault snapshot categories and the fault codes of the current vehicle faults includes: and if the associated fault snapshot categories corresponding to more than two fault categories are the same, storing the fault snapshots of the associated fault snapshot categories, and respectively establishing corresponding relations with the fault codes of more than two current vehicle faults.
Specifically, when the number of the vehicle faults is more than two and the fault categories to which the faults belong are more than two, if the associated fault snapshot categories corresponding to the two or more fault categories are the same, the fault snapshot associated with the fault snapshot category and the fault code of the current vehicle fault are correspondingly stored.
For example, if the associated fault snapshot categories corresponding to the fault categories corresponding to two or more faults occurring in the current vehicle are the same, the fault snapshots are stored in the corresponding fault categories according to the pre-established correspondence relationship between the fault categories and the fault snapshot categories and the correspondence relationship between the fault snapshot categories and the associated fault snapshots, and the storage manner may be that when the fault snapshot categories corresponding to two or more fault categories are the same, the fault snapshots associated with the fault snapshot categories are respectively stored in the storage spaces of the ECUs corresponding to the corresponding fault categories. It can be understood that each fault code corresponds to a group of fault snapshots, and therefore, the fault snapshots are stored in the storage space of the ECU corresponding to the corresponding fault categories according to the pre-established correspondence relationship among the fault snapshots, the fault snapshot categories, and the fault categories.
Optionally, each of the failure snapshots occupies 8 bytes and is stored in a memory or a fixed storage space.
Specifically, when a vehicle has a fault, the vehicle diagnosis device diagnoses the current vehicle, and the vehicle ECU stores vehicle fault information into the storage space, where the vehicle fault information may include information such as a fault snapshot and a fault code. Wherein, the memory occupied by each fault snapshot in the storage space is 8 bytes; the storage space can be a storage space of the vehicle electronic control unit, can also be a preset fixed storage space, is not limited to a specific storage space, and can be set according to actual requirements.
The embodiment of the invention determines the current vehicle fault based on the vehicle-mounted diagnosis equipment, so as to diagnose the current vehicle fault through the vehicle-mounted diagnosis equipment and determine the current vehicle fault, and further, the determined current vehicle fault can be used for identifying the fault category to which the current vehicle fault belongs; and identifying the fault category to which the current vehicle fault belongs, and determining the fault snapshot category corresponding to the fault category according to the corresponding relation according to the identified fault category. Determining a corresponding associated fault snapshot category according to the fault category, wherein the associated fault snapshot category is a partial category in all fault snapshot categories and is used for establishing a corresponding relation between the fault snapshot category and the fault category according to the association degree of the fault snapshot category and storing a fault code corresponding to the fault snapshot according to the corresponding relation; and correspondingly storing the fault snapshot of the associated fault snapshot category and the fault code of the current vehicle fault so as to only store the fault code with strong association degree with the current vehicle fault and not store the fault code with weak association degree with the current vehicle fault, thereby saving the storage space of the electronic control unit. The method solves the problems that the storage quantity is limited and the troubleshooting is inconvenient due to the fact that the occupied space is too large in the traditional storage method of the vehicle fault snapshots, and achieves the effects of reducing the storage space occupied by the vehicle fault snapshots and increasing the storage quantity of the vehicle fault snapshots.
Example two
As an alternative embodiment of the present invention, fig. 2 is a schematic diagram of two vehicle failure categories provided by the second embodiment of the present invention.
In one specific example, when a vehicle has a fault, the vehicle ECU records fault data of the current vehicle fault, such as a fault snapshot of the current vehicle fault and fault code information. When a vehicle diagnostician designs a vehicle fault reference document, vehicle faults are divided into different fault categories according to a correlation relationship, wherein the correlation relationship can be understood as fault data which is possibly related to the faults when the current vehicle is in fault. As can be understood from the correspondence relationship established by the preset vehicle fault reference document, each fault category may include one or more fault snapshot categories, each fault snapshot category includes one or more fault snapshots, and each fault code corresponds to a group of fault snapshots. Meanwhile, each fault snapshot can correspond to one or more fault snapshot categories, and therefore, each fault snapshot can also correspond to one or more fault categories based on the corresponding relation between the fault snapshot categories and the fault categories.
As shown in fig. 2, the number of failures occurring in the vehicle-mounted system of the current vehicle is two, and the category of the failures to which the vehicle-mounted system belongs is two. In the embodiment of the invention, DTC represents a fault code, and SS represents a fault snapshot.
Illustratively, fault class 1 represents an intelligent system network fault, including DTC1, DTC2, and DTC3, and fault class 2 represents a drive train hardware fault, including DTC4 and DTC 5. The fault codes contained in each fault category are different, and therefore, each fault category corresponds to a different related fault snapshot category, that is, each fault category corresponds to a different related fault snapshot. When a vehicle diagnostician makes a complete vehicle design, the controller may be designed to include 50 fault snapshots (SS1-SS50), each of which occupies 8 bytes in the memory space of the ECU.
As shown in fig. 3 and 4, fig. 3 and 4 are schematic views when the vehicle failure categories to which the current vehicle failure belongs are two.
When a vehicle has a fault, according to the pre-established correspondence between the fault type and the fault snapshot type, the fault snapshot type and the fault snapshot, and between the fault snapshot and the fault code, if the fault is highly associated with the fault type 1, the DTC1 belonging to the fault type 1 is reported by the vehicle diagnostic equipment, and then the vehicle ECU stores the relevant fault snapshots SS1, SS2, SS3 and SS4 associated with the fault height. If the occurred fault is highly associated with the fault category 2, the DTC5 belonging to the fault category 2 is reported by the vehicle diagnostic equipment, and then the relevant fault snapshots SS3, SS5, and SS6 associated with the fault are stored by the vehicle ECU.
As shown in fig. 5 and 6, fig. 5 and 6 are schematic diagrams in which the failure categories of the current vehicle failure are two.
The fault code of the fault in fig. 5 is DTC1, the fault category belongs to fault category 1, when the vehicle has a fault, the vehicle diagnostic equipment starts to detect the vehicle fault, and sends a diagnostic request for reading the vehicle fault code DTC1 and the corresponding fault snapshot to the vehicle ECU. After receiving the diagnosis request sent by the vehicle diagnosis device, the vehicle ECU can reply the fault code DTC1 and the corresponding fault snapshots SS1, SS2, SS3 and SS4 to the vehicle diagnosis device.
The fault snapshot code of the fault in fig. 6 is DTC5, the fault category belongs to fault category 2, when the vehicle has a fault, the vehicle diagnostic device starts to detect the vehicle fault, and sends a diagnostic request for reading the vehicle fault code DTC5 and the corresponding fault snapshot to the vehicle ECU. After receiving the diagnosis request sent by the vehicle diagnosis device, the vehicle ECU can reply the fault code DTC5 and the corresponding fault snapshots SS3, SS5 and SS6 to the vehicle diagnosis device.
It is to be noted that, when the fault category 1 and the fault category 2 include the fault snapshot SS3 at the same time, that is, when the same fault snapshot is included in the two fault snapshot categories, the fault snapshots are stored in the storage spaces of the vehicle ECUs corresponding to the two fault categories, respectively.
Since all fault snapshots related to fault categories are stored in the conventional method, each fault snapshot category contains 50 fault snapshots, when two fault categories to which a vehicle fault belongs, for example, the DTC1 in fault category 1 and the DTC5 in fault category 2, occur simultaneously, the vehicle ECU needs to store all fault snapshots SS1-SS50 related to the DTC1 and all fault snapshots SS1-SS50 related to the DTC5, which occupy 916 bytes of storage space of the vehicle ECU, wherein the number of bytes of each fault snapshot category DTC is equal to that of each fault snapshot, and is also 8 bytes.
In the embodiment of the invention, when a vehicle fault document is designed by a vehicle diagnostician, the fault category is preset, and the corresponding relationship between the fault category and the fault snapshot category as well as between the fault snapshot category and the fault snapshot is established, so that when a vehicle has a fault, the fault snapshot related to the fault is only stored according to the preset corresponding relationship, and all fault snapshots are not required to be stored. Therefore, when the DTC1 in fault class 1 and the DTC5 in fault class 2 occur simultaneously, the vehicle ECU only needs to store the SS1, SS2, SS3, and SS4 associated with the DTC1 and the SS3, SS5, and SS6 associated with the DTC5, taking up 72 bytes of vehicle ECU storage space. By the storage mode, a large amount of storage space of the vehicle ECU can be saved, and the storage quantity of the fault snapshots can be increased.
The embodiment of the invention determines the current vehicle fault based on the vehicle-mounted diagnosis equipment, so as to diagnose the current vehicle fault through the vehicle-mounted diagnosis equipment and determine the current vehicle fault, and further, the determined current vehicle fault can be used for identifying the fault category to which the current vehicle fault belongs; and identifying the fault category to which the current vehicle fault belongs, and determining the fault snapshot category corresponding to the fault category according to the corresponding relation according to the identified fault category. Determining a corresponding associated fault snapshot category according to the fault category, wherein the associated fault snapshot category is a partial category in all fault snapshot categories and is used for establishing a corresponding relation between the fault snapshot category and the fault category according to the association degree of the fault snapshot category and storing a fault code corresponding to the fault snapshot according to the corresponding relation; and correspondingly storing the fault snapshot of the associated fault snapshot category and the fault code of the current vehicle fault so as to only store the fault code with strong association degree with the current vehicle fault and not store the fault code with weak association degree with the current vehicle fault, thereby saving the storage space of the electronic control unit. The method solves the problems that the storage quantity is limited and the troubleshooting is inconvenient due to the fact that the occupied space is too large in the traditional storage method of the vehicle fault snapshots, and achieves the effects of reducing the storage space occupied by the vehicle fault snapshots and increasing the storage quantity of the vehicle fault snapshots.
