detailed description

At present, in the remote diagnosis process of the vehicle, the remote server can receive and analyze the fault information reflecting the fault status of the vehicle, obtain the fault diagnosis result information corresponding to the fault, and send the fault result information. It can be seen from this that the entire remote diagnosis process is relatively fixed and not targeted, thus resulting in low efficiency of the entire remote diagnosis process.

In order to solve the above-mentioned problems, the embodiment of the present invention provides a method for remote diagnosis of vehicles, by judging the fault level of the vehicle according to the fault code information from the vehicle, and then targeted according to different fault levels For minor faults, the fault codes are cleared directly, which can prevent users from having to go to the repair site to repair the vehicle when the vehicle has only minor faults, thereby improving remote diagnosis. s efficiency.

In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

FIG. 1 shows a flow chart of a method for remote vehicle diagnosis in an embodiment of the present invention. The specific steps included in the diagnosis method will be described in detail below in conjunction with FIG. 1 .

S11: Receive a diagnosis request from a user.

In specific implementation, when the user wants to remotely diagnose the vehicle, the diagnosis request can be sent in various ways. For example, the user can send the diagnosis request by using the mobile phone APP, and the location When there is no network, the diagnosis request can also be sent by calling the service center, and of course the user can also send the diagnosis request through a computer at home.

After receiving the diagnostic request from its own user, execute S12; otherwise, end the process.

In a specific implementation, in order to facilitate the user to remotely diagnose the vehicle at a suitable time, it may also be determined according to the diagnosis request whether the scheduled time for the user to diagnose the vehicle is the current time. If the time point is not the current time, then send the remote diagnosis instruction to the vehicle specified in the diagnosis request at the scheduled time point.

S12: Send a remote diagnosis instruction to the vehicle specified in the diagnosis request.

In a specific implementation, in order to diagnose and control the vehicle, after receiving the diagnosis request from the user, the diagnosis request can be parsed first, and the vehicle that the user wants to perform remote diagnosis can be known, and then the user can verify the relationship between the user and the vehicle. After the information between the two vehicles is successfully matched, the diagnosis request can be converted into a corresponding remote diagnosis instruction, and finally the remote diagnosis instruction can be sent to the specified vehicle.

S13: Receive fault code information sent according to the remote diagnosis instruction from the vehicle.

In a specific implementation, in order to know the real condition of the vehicle, after the remote diagnosis command is sent to the vehicle, information reflecting the fault condition of the vehicle may be received from the vehicle. For example, the fault code information of the vehicle can be received, and the fault code information can include the fault code displayed by the control unit of the faulty component, and can also include the status information of the vehicle when the fault code occurs, for example What was the speed of the vehicle in question when the breakdown occurred.

S14: Judging the fault level of the vehicle according to the fault code information, performing diagnostic analysis on the fault, and sending the diagnostic analysis result to the user.

In a specific implementation, in order to deal with each fault in a targeted manner, the fault level of the vehicle may be judged according to the fault code information.

In a specific implementation, each of the remote diagnosis instructions can be directly directed to one electronic control unit on the vehicle, or can be executed in batches for multiple electronic control units. When the instructions are executed in batches for multiple electronic control units, the fault level of the entire vehicle is the same as the highest fault level among the multiple electronic control units.

In a specific implementation, in order to obtain the detailed information of the fault, a diagnostic analysis may be performed on the fault. There are many methods for the diagnosis and analysis. For example, the diagnosis and analysis of the failure can be performed directly according to the system failure database, or the diagnosis and analysis of the failure can be directly performed by a diagnostic expert and output to the user. In an embodiment of the present invention, the fault diagnosis and analysis results for the fault can be obtained by combining the system fault database and diagnostic experts' opinions, thereby improving the accuracy and comprehensiveness of fault diagnosis.

When the fault level is a minor fault, execute S15; when the fault level is a moderate fault, execute S16; when the fault level is a serious fault, execute S17.

S15: Clear the fault code on the vehicle, and notify the user that the vehicle can continue to be driven.

In specific implementation, in order to improve the efficiency of diagnosis, when it is determined that the level of the fault is a minor fault, which means that the fault of the vehicle is not serious and will not affect normal driving, the vehicle can be cleared. and notify the user that he can continue to drive the vehicle, which saves the user the trouble of going to a repair place to repair the vehicle. Not only that, but the diagnostic analysis result can also be sent to the user for reference and decision-making by the user.

S16: Informing the user to go to a vehicle maintenance site to maintain the vehicle.

In a specific implementation, when it is determined that the fault of the vehicle is at a medium level, that is, if you continue to drive, it may cause potential driving safety. In order to avoid this problem, the user can be notified to go to a vehicle maintenance site to maintain the vehicle , thereby improving driving safety.

S17: Informing the user to keep the vehicle stationary for on-site maintenance.

In a specific implementation, when it is determined that the fault of the vehicle is a serious fault, it is determined that the vehicle can no longer be driven normally. At this time, the user may be notified to directly keep the vehicle in place, and contact relevant personnel to repair the vehicle on site, so as to reduce the loss of the vehicle.

In an embodiment of the present invention, after the maintenance of the vehicle is completed, if the fault code still exists, in order not to affect the use of the vehicle by the user and avoid misunderstanding by the user, the fault code on the vehicle can be cleared. of the fault codes.
