Description
Technical Field
The application belongs to the technical field of vehicle diagnosis, and particularly relates to a vehicle detection method, a vehicle detection device and vehicle diagnosis equipment.
Background
With the rapid development of the vehicle (such as automobile) industry, the popularity of vehicles in human life is higher and higher. In order to improve the safety of the vehicle in the using process, the vehicle needs to be detected before the vehicle leaves a factory, and if the obtained detection result indicates that the vehicle is unqualified, the vehicle needs to be detected again until the vehicle is qualified, so that the vehicle can not leave the factory.
In the existing vehicle detection method, a vehicle is detected on line through a diagnosis device on the line, and if the obtained detection result indicates that the vehicle is unqualified, the unqualified vehicle is detected again through the diagnosis device in a repair area. For example, after the employee performs a complete on-line detection process again in the repair area, a re-inspection detection result is obtained, and whether the vehicle is qualified is determined according to the re-inspection detection result; or, when the staff detects on line, the staff manually records detailed error information to the vehicle-mounted card, and then determines the actual error Electronic Control Unit (ECU) system of the vehicle in the repair area by combining the error information on the vehicle-mounted card, and finally, manually and one by one selects the error ECU system to perform the rechecking operation. In the existing vehicle detection method, if complete on-line detection is executed once again in a repair area, excessive detection time is consumed; if the detailed error information is manually recorded to the vehicle-mounted card by the staff, and the ECU system corresponding to the error information is manually selected by the staff for retesting in the repair area, the error is easy to occur, and the detection efficiency is low due to the fact that a large amount of manual operation is needed.
Therefore, it is necessary to provide a new method to solve the above technical problems.

The first embodiment is as follows:
in the existing vehicle (such as automobile) detection method, after an on-line diagnosis device reports an error, the vehicle needs to be moved to a repair area, and then, an employee in the repair area manually selects a corresponding error ECU to perform retest according to error information recorded by an onboard card. Because the worker manually selects the wrong ECU for rechecking, the probability of selection error is high, and the selection speed through manual operation is low, so that the detection time of the whole vehicle is prolonged, and the detection efficiency is low. In order to solve the above technical problem, an embodiment of the present application provides a new Vehicle detection method, in the Vehicle detection method, since a comprehensive detection result of a Vehicle includes a Vehicle Identification Number (VIN) and error information, after the Vehicle arrives at a station in a repair area, a diagnostic device can determine a comprehensive detection result of the Vehicle to be repaired according to the Vehicle Identification Number after acquiring the Vehicle Identification Number, and then determine the error information in the comprehensive detection result, and then perform a retest on the Vehicle according to the determined error information, that is, the Vehicle is retested after an ECU is not manually selected, so that a detection duration of the Vehicle is reduced, and a detection efficiency of the Vehicle is greatly improved.
In order to describe the vehicle detection method provided in the embodiments of the present application in detail, the following description is made with specific embodiments.
Fig. 1 shows a flowchart of a vehicle detection method provided in an embodiment of the present application, which is applied to a diagnostic device with diagnostic software installed, and details are as follows:
and step S11, acquiring the vehicle identification number, and determining the comprehensive detection result of the vehicle to be repaired according to the vehicle identification number, wherein the comprehensive detection result comprises the vehicle identification number and the error information of the vehicle to be repaired.
In the present embodiment, when the diagnostic apparatus determines the comprehensive detection result of the vehicle to be repaired based on the vehicle identification number, the following manner may be adopted: the diagnosis equipment acquires the vehicle identification number according to the vehicle identification number input by a user or a code scanning gun, and searches a comprehensive detection result corresponding to the vehicle to be repaired at a station of the repair area according to the vehicle identification number, wherein the comprehensive detection result comprises the vehicle identification number and error information of the vehicle to be repaired. The error information is used to describe the problem of the vehicle to be repaired during detection, for example, which ECU system of the vehicle to be repaired has a problem, what problem has occurred, and the like.
Step S12, determining corresponding error information according to the integrated detection result.
In this embodiment, the diagnostic device parses error information corresponding to the comprehensive detection result according to a preset data structure.
And step S13, rechecking the vehicle to be repaired according to the error information to obtain a second detection result, wherein the second detection result is used for indicating whether the vehicle to be repaired is qualified or not.
In this embodiment, the diagnostic device determines, from the error information, an ECU system (for example, an ECU system of an engine) that needs to be rechecked in the vehicle to be repaired, and then rechecks the ECU system that needs to be rechecked to obtain a second detection result of the vehicle to be repaired. In some embodiments, when the second detection result does not include error information (if the second detection result does not include information that needs to be rechecked again), or the second detection result includes information that the vehicle is qualified, the second detection result indicates that the vehicle to be repaired is qualified after rechecking, otherwise, the second detection result indicates that the vehicle to be repaired is unqualified after rechecking.
In the embodiment of the application, the comprehensive detection result of the vehicle comprises the vehicle identification number and the error information, so that after the vehicle identification number is acquired, the diagnostic equipment can determine the comprehensive detection result of the vehicle to be repaired according to the vehicle identification number, then determine the error information in the comprehensive detection result, and then recheck the vehicle according to the determined error information, namely, the vehicle is rechecked after the ECU is not manually selected, therefore, the detection time of the vehicle is shortened, and the detection efficiency of the vehicle is greatly improved.
Fig. 2 shows a flowchart of another vehicle detection method provided in the embodiment of the present application, which is applied to a diagnostic device with diagnostic software installed, and is detailed as follows:
step S21, performing online detection on the vehicle to be detected, and generating a first detection result, where the first detection result includes the vehicle identification number of the vehicle to be detected, or the first detection result includes the vehicle identification number and the error information of the vehicle to be detected.
The vehicle to be detected is a vehicle to be detected, and the on-line detection of the vehicle to be detected refers to the detection of the vehicle on a production line through a diagnosis device.
In this embodiment, the diagnostic device is installed with diagnostic software that has been previously designed with a data structure for storing the detection results, including the first detection result and the second detection result described above. In this way, after the diagnostic device performs online detection on the vehicle to be detected according to the instruction of the diagnostic software, the diagnostic software can store the information of the first detection result in a classified manner according to the designed data structure, and can subsequently accurately extract the required information according to the classification of the data structure, for example, if the vehicle identification number is identified as V in the data structure, the vehicle identification number of the vehicle can be extracted from the category V.
In some embodiments, in order to facilitate a user to more intuitively view the detection results of different ECU systems, the data structure for storing the detection results includes a vehicle identification number and error information, and at this time, the error information includes a system name where a problem occurs (ECU system name) and a description of a specific problem that occurs. The data structure may also include a system name, a vehicle identification number, and error information, where the error information primarily includes a description of the specific problem that occurred. In some embodiments, the data structure described above may also include a detection time. When the detection result includes the error information, it indicates that the vehicle corresponding to the detection result is unqualified, for example, if the first detection result stores the corresponding information in the system name, the vehicle identification number and the item of the error information in the data structure, it indicates that the vehicle to be detected is unqualified. And when the first detection result respectively stores corresponding information in the system name and the vehicle identification number in the data structure, the vehicle to be detected is qualified.
Step S22, obtaining a vehicle identification number, and determining a comprehensive detection result of the vehicle to be repaired according to the vehicle identification number, where the comprehensive detection result includes the first detection result, and the vehicle to be repaired is the vehicle to be detected whose first detection result includes the error information.
In this embodiment, after the vehicle to be detected passes through the online detection, if the first detection result of the vehicle to be detected includes the error information, the vehicle to be detected needs to be rechecked at the station of the repair area. That is, only the vehicle to be detected, which passes through the online detection and whose corresponding first detection result contains the error information, is taken as the vehicle to be repaired of the present embodiment, and the vehicle to be detected, which passes through the online detection but whose corresponding first detection result does not contain the error information, does not belong to the vehicle to be repaired of the present embodiment.
It should be noted that, when the vehicle to be repaired only passes through the on-line detection, the comprehensive detection result of the vehicle to be repaired only includes the first detection result, that is, the comprehensive detection result of the vehicle to be repaired is the first detection result. When the vehicle to be repaired passes through the on-line detection and is subjected to at least one re-inspection at the station of the repair area, the comprehensive detection result of the vehicle to be repaired comprises a second detection result besides the first detection result.
In some embodiments, in order to avoid moving the vehicle to be detected that does not need to be retested to the repair area station, the vehicle to be detected that is detected on the pass line and needs to be retested is identified, so that the employee can select to move the corresponding vehicle to be detected to the repair area station according to the identification, and the vehicle to be detected that is moved to the repair area station is the vehicle to be repaired of this embodiment. For example, when the diagnostic device performs online detection on a vehicle to be detected, the vehicle-mounted card is delivered to the vehicle to be detected, which needs to be rechecked, by controlling the manipulator, and the information recorded by the vehicle-mounted card can be: requiring a review. Of course, the information recorded by the vehicle-mounted card may be other contents, and only needs to include the contents that the vehicle needs to be rechecked. The information recorded on the card may be recorded by an employee or may be printed in advance by a machine, and is not limited herein. In this embodiment, because the vehicle to be detected that needs retest carries out the sign, consequently, the staff only can move the vehicle to be detected that has the sign to repair the district station, and can not move the vehicle to be detected that need not retest to repair the district station by mistake to greatly improve the detection efficiency of vehicle.
Step S23, determining corresponding error information according to the integrated detection result.
In this embodiment, if the integrated detection result only has the first detection result, the error information included in the first detection result is directly determined according to the first detection result.
And step S24, rechecking the vehicle to be repaired according to the error information to obtain a second detection result, wherein the second detection result is used for indicating whether the vehicle to be repaired is qualified or not.
In the embodiment of the application, the first detection result is recorded by the diagnostic equipment and is not manually recorded, so that the accuracy of the recorded first detection result is improved, and the time length required for recording the first detection result is reduced. In addition, the vehicle is rechecked by the diagnostic equipment according to the error information, namely, the vehicle is rechecked after the ECU is not manually selected, so that the detection time of the vehicle is further shortened, and the detection efficiency of the vehicle is greatly improved.
In some embodiments, after the vehicle to be repaired is subjected to the one-time re-inspection, if the obtained second detection result includes the vehicle identification number, the detection time and the error information of the vehicle to be repaired, it indicates that the second detection result indicates that the vehicle to be repaired is unqualified, that is, the vehicle to be repaired subjected to the one-time re-inspection needs to be re-inspected again, and at this time, the comprehensive detection result of the vehicle to be repaired includes the second detection result obtained when the vehicle to be repaired is subjected to the re-inspection in addition to the first detection result. That is, the comprehensive detection result of the vehicle to be repaired further includes the second detection result, the second detection result includes the vehicle identification number of the vehicle to be repaired, the detection time and the error information, and the first detection result further includes the detection time.
The step S23 includes:
a1, determining the latest detection result according to the detection time of the first detection result included in the integrated detection result and the detection time of the second detection result included in the integrated detection result.
And A2, determining corresponding error information according to the latest detection result.
In this embodiment, if the detection time of the first detection result is "2020.08.01.05" and the detection time of the second detection result is "2020.08.02.05", the detection time of "2020.08.02.05" is the latest detection time, and the detection result corresponding to the latest detection time is the latest detection result, that is, the diagnostic device can determine the latest detection result according to the detection time in the integrated detection result, and further determine the corresponding error information according to the latest detection result.
In this embodiment, after querying out the comprehensive detection result of the corresponding vehicle according to the VIN, the diagnostic device determines the latest detection result according to the detection time, that is, it is ensured that the subsequently obtained error information is also the latest, so that the accuracy of performing the subsequent rechecking on the vehicle according to the error information can be ensured.
In some embodiments, after this step S24, it includes:
and returning to the step of executing the A1 and the subsequent steps until the second detection result indicates that the vehicle to be repaired is qualified.
In this embodiment, when the second detection result does not include the error information, it indicates that the vehicle to be repaired is qualified after the rechecking. The diagnostic equipment automatically records the corresponding second detection result when the vehicle to be repaired is subjected to re-inspection, so that manual recording is not needed, and the re-inspection time of the vehicle to be repaired is saved. In addition, when the vehicle to be repaired needs to be rechecked again, the diagnostic equipment acquires the comprehensive detection result of the vehicle to be repaired, namely, the first detection result and the second detection result of the vehicle to be repaired, and selects the latest detection result, for example, the latest second detection result according to the detection time included in the first detection result and the second detection result. Due to the fact that the latest detection result is selected all the time, the error information of the vehicle to be repaired can be conveniently and accurately acquired subsequently, the vehicle to be repaired can be rechecked according to the more accurate error information, and the rechecking detection efficiency is improved.
In some embodiments, after the a1, comprising:
and displaying error information in the latest detection result.
In this embodiment, in order to facilitate the staff to quickly know the problem of the vehicle to be repaired, the diagnostic device in the repair area displays the error information in the latest detection result after acquiring the latest detection result. Of course, in addition to displaying the error information, the system name, the vehicle identification number, the detection time, and the like in the latest detection result may be displayed.
In some embodiments, after the displaying the error information in the latest detection result, the method further includes:
the diagnostic device prompts the user to repair the vehicle to be repaired.
The A2 comprises:
and after the user maintains the vehicle to be repaired, determining corresponding error information according to the latest detection result.
Wherein the error information includes a functional failure and a failure code, and the functional failure is description information of the failure code. For example, when the system name is "engine", the functional fault may be a "failure to read fault code" which may be an "open throttle position sensor". That is, when a user (or staff) performs maintenance, the vehicle to be repaired is rechecked according to the fault code, and the diagnostic equipment automatically rechecks the vehicle to be repaired by resolving the 'functional fault' and the 'fault code' in the error information. Of course, if the detection result further includes the system name, the diagnostic device in the repair area will automatically perform the retest on the vehicle to be repaired in combination with the "system name", "functional failure", and "failure code". For example, if a vehicle to be repaired needs to detect an Engine Management System (EMS), an airbag Restraint System (SRS), and they need to execute functions of (EMS: writing VIN code, writing Injection Quantity Adjustment (IQA) code, SRS: activating, clearing fault code, reading fault code), the diagnostic software of the diagnostic device in the repair area executes the above listed functions according to the above information. If the function of writing the VIN code by the EMS fails in the last detection process, the diagnostic device in the repair area acquires the failed information, and finally recombines the detection information into (EMS: VIN code) after analyzing the data, that is, in the embodiment of the application, the diagnostic device in the repair area only executes the function of writing the VIN code by the EMS, and other functions such as writing the IQA code by the EMS and activating the SRS cannot be executed, so that the purposes of reducing the detection items of the re-detection and saving the detection time can be achieved.
In this embodiment, prompting the user to repair the vehicle to be repaired means prompting the user according to the fault code, for example, directly broadcasting the fault code.
In some embodiments, since the error information in the latest detection result may be caused by a problem existing in the vehicle itself, or may be caused by a problem existing in a diagnostic device (such as a diagnostic device located on a production line or a diagnostic device located in a repair area) itself, the prompting user performs maintenance on the vehicle to be repaired, including:
and if the error information in the latest detection result is the error information of the vehicle to be repaired, prompting a user to repair the vehicle to be repaired.
In the embodiment, the user is prompted to maintain the vehicle to be repaired after the error information is judged to be the error information of the vehicle to be repaired, but not the error information of the diagnosis equipment or other equipment, so that the prompting accuracy is improved.
In some embodiments, if the error information in the latest detection result is the error information of a vehicle not to be repaired, the vehicle to be repaired is re-detected by using the detection process corresponding to the next-new detection result.
In this embodiment, when the diagnostic device in the repair area determines that the error information in the latest detection result is not the error information of the vehicle to be repaired, each function of the vehicle to be repaired is re-detected. Since the detection result of the vehicle to be repaired is inaccurate when the error information is not the error information of the vehicle to be repaired, the accuracy of the detection result can be improved by re-detecting the vehicle to be repaired by performing the detection flow corresponding to the second-to-last detection result on the vehicle to be repaired. For example, if the vehicle to be repaired is subjected to the first retest to obtain the second detection result (the on-line detection before the retest obtains one first detection result), at this time, the latest detection result is the second detection result, and the next latest detection result is the first detection result, then the diagnostic device performs the overall detection on the vehicle to be repaired in the retest area by using the detection procedure completely the same as the on-line detection. Assuming that the vehicle to be repaired is rechecked for 2 times to obtain 2 second detection results, the latest detection result is the second detection result obtained later, and the next latest detection result is the second detection result obtained earlier, at this time, the diagnostic device rechecks the vehicle to be repaired by adopting the detection flow corresponding to the second detection result obtained earlier when the vehicle to be repaired is rechecked in the repair area, and the detection at this time is usually partial detection.
In this embodiment, after determining that the diagnostic device (on-line diagnostic device or repair area diagnostic device) is not qualified, the user needs to perform maintenance according to the operation instruction of the diagnostic device.
In some embodiments, in order to improve the accuracy of the obtained detection result as much as possible, when the vehicle to be detected is detected online, the diagnostic device performing online detection (i.e. the online diagnostic device) also needs to be detected, and in this case, the error information of the vehicle not to be repaired is the error information of the diagnostic device, that is: if the error information of the non-vehicle to be reworked is the error information of the diagnostic device, the step S21 includes:
the method comprises the steps of detecting a diagnosis device, performing online detection on a vehicle to be detected through the diagnosis device, and generating a first detection result, wherein when the detection result of the diagnosis device indicates that the diagnosis device is unqualified, the first detection result comprises a vehicle identification number and error information of the vehicle to be detected, and the error information comprises the error information of the diagnosis device.
In this embodiment, if it is detected that the diagnostic device has a problem, the diagnostic device is continuously used to perform online detection on the vehicle to be detected, so as to avoid blocking the subsequent detection of the vehicle to be detected. Compared with the first detection result obtained after the on-line detection is performed by the diagnosis device without the problem, the difference is that the first detection result obtained after the on-line detection is performed on the vehicle to be detected by the diagnosis device with the problem comprises the error information of the diagnosis device, and the error information of the diagnosis device can be the error of the diagnosis device.
In some embodiments, when the diagnostic device rechecks the vehicle to be reworked, it is also necessary to check the diagnostic device (also referred to as the diagnostic device of the rework area). And if the diagnostic equipment in the repair area is unqualified, the obtained second detection result comprises the vehicle identification number of the vehicle to be repaired, the detection time and error information, and the error information comprises the error information of the diagnostic equipment in the repair area.
In some embodiments, after step S11, the diagnostic device displays the integrated test results of the vehicle to be repaired, so that the employee can view the individual test results included in the integrated test results.
Wherein, the displayed comprehensive detection result can be as follows: vehicle identification number, system name, functional fault, fault code, and detection time. It should be noted that, when there are multiple data in any parameter of the integrated detection result, it will be displayed in a list form for the user to view conveniently, for example, if there are multiple fault codes, it will be displayed in a fault code list, and the fault codes may be defined according to the vehicle itself.
In this embodiment, the user can search the detection results corresponding to the returnable vehicles at different detection times through the comprehensive detection result displayed by the terminal. The user can also access the latest detection result through the comprehensive detection result, and further judge whether the error information is the error information of the vehicle to be repaired or not according to the error information in the latest detection result.
In order to more clearly describe the detection process of the vehicle, the following description is given in terms of specific application examples:
fig. 3 is a schematic flow chart illustrating an on-line detection process of the vehicle under test by the on-line diagnostic device according to the diagnostic software with a designed data structure, where in fig. 3:
