detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A vehicle diagnostic apparatus embodying various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, the use of suffixes such as "module", "component" or "unit" for indicating an element is merely an explanation for facilitating the present invention, and does not have a specific meaning per se. Therefore, "module" and "component" can be used in combination.

The vehicle diagnostic device is a diagnostic instrument for detecting and diagnosing various functional parameters of the vehicle, and can detect various performance indexes of the vehicle in real time, and comprehensively diagnose the performance state of the vehicle according to the performance index, which is an essential for the vehicle detecting personnel. Kind of diagnostic tool.

When the vehicle diagnosis device performs detection and diagnosis on the vehicle, the inspection personnel are required to artificially control the vehicle diagnosis device. When the inspector uses the vehicle diagnostic device, the inspector is the user of the vehicle diagnostic device. The vehicle diagnostic device requires the user to operate at the vehicle diagnostic device before performing the detection diagnostic function on the vehicle, thereby determining that the vehicle diagnostic device performs a corresponding function to the detected vehicle. The vehicle diagnostics device displays fixed diagnostic options for the user to select according to the established procedure. Even if the user frequently uses certain diagnostic options, the required diagnostic options need to be selected one by one.

Based on the functions of the above-described conventional vehicle diagnosis device, the vehicle diagnosis option display method and the vehicle diagnosis device of the present invention are proposed.

The present invention provides a vehicle diagnostic option display method, which is mainly applied to a vehicle diagnostic device. In a first embodiment of the vehicle diagnostic option display method, referring to FIG. 1, the vehicle diagnostic option display method includes:

Step S10, when detecting the identity authentication information input by the user, determining whether there is an authentication account corresponding to the identity authentication information in the vehicle diagnostic device;

The vehicle diagnostic device may be a fixed vehicle diagnostic terminal, or may be a portable vehicle diagnostic device or other related vehicle diagnostic product or the like. In this embodiment, to implement the function of identifying the user's personal information, it is necessary to input the identity authentication information having the user-specific identifier in advance. Users can enter identity authentication information in a variety of ways, such as manually entering job numbers, digital passwords, or active input or passive authentication of identity authentication information through biometric scanning technologies such as iris recognition, face recognition, and fingerprint recognition. Input.

In the storage unit of the vehicle diagnostic device, an authentication account (ie, ID) having identity information registered with the vehicle diagnostic device is stored, and the account has a corresponding account when the account is operated by the vehicle diagnostic device. A record of diagnostic options or information. Different accounts have their own records and do not affect each other.

When the onboard diagnostic device detects and receives the identity authentication information input by the user, the vehicle diagnosis device can verify whether the identity authentication information is valid information. The criterion is that the identity authentication information input by the user is used as reference data to determine whether there is an authentication account corresponding to the reference data in the database of the vehicle diagnostic device. If the authentication account exists, it proves that there is account information bound to the identity authentication information in the vehicle diagnosis device, that is, the user is an authentication account of the vehicle diagnosis device, and can use various functions of the vehicle diagnosis account, and can adjust A record of various diagnostic options or information is taken; if the authentication account is not present, it is proved that the identity authentication information does not exist in the vehicle diagnosis terminal, the user authentication fails, and various diagnostic options or information records cannot be retrieved.

Step S20: When an authentication account corresponding to the identity authentication information exists in the vehicle diagnosis device, obtain a usage frequency of all the diagnosis options in the authentication account.

Assuming that the database of the vehicle diagnostic device can query the authentication account corresponding to the identity authentication information, the user is authenticated to have a record of the diagnostic option or information that the vehicle diagnostic device is capable of using to retrieve the authentication account. The vehicle diagnostic device will display the past diagnostic options or information records of the authentication account, and display them to the user in a form in which the frequency of use is arranged from large to small. Since the user leaves a usage operation record of various diagnostic options for detection or diagnosis in the process of detecting the performance index or the diagnostic performance status of the vehicle in the past, the vehicle diagnosis device can retrieve the operation record and extract the operation. The frequency of use of various diagnostic options in the record. The frequency of use is an important reference data for realizing the technical effects of the technical solution of the present invention.

In step S30, the diagnostic options are sorted according to the corresponding use frequency, and the previous preset number of diagnostic options in the arrangement are displayed.

Arranging the frequency of use from large to small means that the diagnostic options corresponding to the frequency of use are arranged from large to small, and the arrangement reflects the user's usage habits, that is, the user performs the previous vehicle detection and diagnosis functions. Frequently used functions, and this trend is recorded by the vehicle diagnostic device. In order to facilitate the user to quickly and conveniently use the functions, the diagnostic options corresponding to the functions are sorted. Since the display interface of the vehicle diagnostic device is limited, only It is necessary to list several diagnostic options that users often use, without having to display them all. The preset number can be customized by the user.

To assist in understanding this embodiment, the following will be explained by a specific example:

The vehicle diagnostic device detects whether the input identity authentication information is received in real time. When detecting and receiving the identity authentication information input by the user, the vehicle diagnosis device queries the database for the identity authentication information, and if so, obtains the identity authentication. The authentication account corresponding to the information. The vehicle diagnostic device can obtain the previous operation record of the authentication account, etc., and assume that the user of the authentication account frequently detects the model a vehicle of the A brand vehicle, and in the authentication account, the diagnostic option of the model a vehicle of the A brand vehicle The frequency of use will be higher. At this time, the vehicle diagnosis device acquires a diagnosis option or the like related to the model a vehicle of the A-brand vehicle, and displays it in such a manner that the frequency of use of the diagnosis option is arranged from large to small. That is, the vehicle diagnostic device preferentially displays the diagnostic option of the a-type vehicle of the A-brand vehicle with a high frequency of use, and the higher the usage frequency, the higher the ranking of the corresponding diagnostic option displayed on the vehicle diagnostic device. The vehicle diagnostic device refers to the frequency of use of certain user-specific diagnostic options in the past, and intelligently displays the user's previously used diagnostic options with higher priority for the user to select.

In the technical solution of the present invention, first, when the identity authentication information input by the user is detected, it is determined whether there is an authentication account corresponding to the identity authentication information in the vehicle diagnosis device; and then, when the vehicle diagnosis device has corresponding to the identity authentication information, When the account is authenticated, the frequency of use of all the diagnostic options in the authentication account is obtained; finally, the diagnostic options are sorted according to the corresponding use frequency, and the preset preset number of diagnostic options in the arrangement are displayed. . In the above manner, the vehicle diagnostic device intelligently customizes the diagnostic option that meets the usage habits of the tester, simplifies the operation process of the vehicle diagnosis process, improves the work efficiency of the tester and the overall vehicle diagnosis efficiency, and realizes the technology for rapid vehicle diagnosis. The effect makes the vehicle diagnosis process convenient and fast, which greatly improves the experience of the tester.

Further, based on the first embodiment of the vehicle diagnostic option display method of the present invention, a second embodiment of the vehicle diagnosis option display method is proposed. Referring to FIG. 2, the difference between the second embodiment and the first embodiment lies in The identity authentication information includes face authentication information and fingerprint authentication information.

When the identity authentication information input by the user is detected, determining whether the authentication account corresponding to the identity authentication information exists in the vehicle diagnostic device includes:

Step S11, when the face authentication information is detected, determining whether there is an authentication account corresponding to the face authentication information in the vehicle diagnosis device;

Step S12, when the fingerprint authentication information is detected, it is determined whether there is an authentication account corresponding to the fingerprint authentication information in the vehicle diagnostic device.

The authentication method of the vehicle diagnostic device may be face recognition authentication or fingerprint identification authentication. In this embodiment, as a preferred solution of the present invention, when the authentication mode of the vehicle diagnostic device is face recognition authentication, the user can trigger the face recognition command by itself, or the vehicle diagnosis device automatically generates a face recognition command, thereby completing the active or passive input identity. Certification Information.

For example, the vehicle diagnostic device detects whether the identity authentication information is received in real time, and when the user enters the face recognition area of the vehicle diagnosis device, and the vehicle diagnosis device acquires the face recognition command, acquires the face authentication information of the current user, and Using the face authentication information as reference data, determining whether the face authentication information exists in the database of the vehicle diagnosis device, and if so, obtaining an authentication account corresponding thereto;

Alternatively, when the user is in the fingerprint identification area of the vehicle diagnosis device, and the vehicle diagnosis device acquires the fingerprint identification instruction, the fingerprint authentication information of the current user is acquired, and the fingerprint authentication information is used as reference data to determine whether the database of the vehicle diagnosis device is in the database. The fingerprint authentication information exists, and if so, the authentication account corresponding thereto is obtained.

It should be noted that the face authentication information and the fingerprint authentication information may be separately authenticated or may be subjected to secondary authentication. That is, the authentication method in this embodiment may implement alternate authentication according to actual conditions, and perform fingerprint authentication after face authentication is completed. In order to more accurately identify the user's identity authentication information, thereby obtaining the corresponding authentication account.

Further, based on the first embodiment of the vehicle diagnostic option display method of the present invention, a third embodiment of the vehicle diagnosis option display method is proposed. Referring to FIG. 3, the difference between the third embodiment and the first embodiment lies in And the step of sorting the diagnostic options according to the corresponding use frequency from large to small, and displaying the pre-preset number of diagnostic options in the arrangement further includes:

Step S40, when the vehicle diagnosis device detects the operation of the user's authentication account based on the diagnosis option, the frequency of use of the diagnosis option is counted;

After the vehicle diagnostic device switches to the user's authentication account, the user can normally use the various diagnostic options of the vehicle diagnostic device on the vehicle diagnostic device. Since the vehicle diagnosis device registers the user's authentication account at this time, the user will be recorded by the vehicle diagnosis terminal based on the operation on the diagnosis option of the vehicle diagnosis device. The vehicle diagnostic device counts the user's operational items and then counts them to obtain the frequency of use of the user based on the operation on the diagnostic option. That is, once the user performs a functional operation on the vehicle diagnostic device, the vehicle diagnostic device acquires the operation target (ie, the diagnostic option) in the current operation and the frequency of use of the user to operate the diagnostic option.

In step S50, the diagnosis option and the corresponding use frequency are associated with the user's authentication account and stored.

After obtaining the frequency of use of the statistics and the corresponding diagnostic option, the vehicle diagnostic device stores the diagnostic option operated by the user and the corresponding use frequency in the storage unit of the vehicle diagnostic device for the display basis of the next user operation.

Further, based on the third embodiment of the vehicle diagnostic option display method of the present invention, a fourth embodiment of the vehicle diagnosis option display method is proposed. Referring to FIG. 4, the difference between the fourth embodiment and the third embodiment lies in And the step of sorting the diagnostic options according to the corresponding use frequency from large to small, and displaying the pre-preset number of diagnostic options in the arrangement further includes:

Step S60, when detecting a user-set custom setting instruction, the vehicle diagnosis device sets a display order of the diagnosis options based on the user's setting instruction;

Step S70, displaying a preset number of diagnostic options in the display order.

The technical solution of the present invention is to provide a diagnosis option that meets the user's usage habits for the user to use quickly. When the user's usage habits change, there will be no strong demand for the diagnostic option with the higher frequency of use in a certain period of time, but there is a certain demand for other diagnostic options; or the user needs to use it first. The data of a certain function starts to execute the diagnostic option with high frequency. For example, if the user originally tested the vehicle belonging to the A brand, the diagnostic option related to the A brand a car will be used more frequently; now the user only detects the b car of the diagnostic B brand, and the need is Diagnostic options related to the B brand b car no longer require diagnostic options related to the A brand car. However, the vehicle diagnostic device will always display the diagnostic options associated with the A brand a car because it is used more frequently than the diagnostic options associated with the B brand b car. At this time, the user can trigger a custom setting instruction to set it by itself, and set the display order of the diagnostic options by the user's setting instruction. That is, in addition to the frequency of use, the priority display of the diagnostic option is directly set. Then, a predetermined number of diagnostic options in the display order are displayed (where the preset number can be set by the user). For example, the A-brand a-vehicle-related diagnostic option is used more frequently, so it has been shown that the user only needs to set the diagnostic option of the B-brand b car in the front, then the diagnostic option of the B-brand b car will not be used. The effect is thus displayed first.

Further, based on the fourth embodiment of the vehicle diagnostic option display method of the present invention, a fifth embodiment of the vehicle diagnostic option display method is proposed. The difference between the fifth embodiment and the fourth embodiment is that the When the identity authentication information input by the user is detected, the step of determining whether the authentication account corresponding to the identity authentication information exists in the vehicle diagnostic device further includes:

When there is no authentication account corresponding to the identity authentication information in the vehicle diagnosis device, the prompt information of the authentication failure is displayed.

There is no authentication account corresponding to the identity authentication information in the vehicle diagnostic device.

1. The vehicle diagnostic device fails to obtain the correct identity authentication information, resulting in the identity authentication information not present in the vehicle diagnostic device. For example, the user input number is incorrect, or the user does not input fingerprint authentication information or face authentication information according to the correct process;

2. The vehicle diagnostic device acquires the correct identity authentication information, but does not have an authentication account corresponding to the identity authentication information in its database. For example, the user enters the correct job number, but the authentication account of the job number has been deleted or blacklisted.

The above two cases are only examples. When there is no authentication account corresponding to the identity authentication information in the vehicle diagnosis device, the prompt information of the authentication failure is displayed to remind the user to re-enter the identity authentication information.
