Embodiment 1

[0041] Like the fault diagnosis system described above, the present embodiment differs from it in that the running signals include signals from various parts of the vehicle and multiple signals measured in a short period of time at the same part, and the merging formula for merging signals of the diagnostic device 3 is:

[0042] x j = Σ i = 1 n x i j N i Σ i = 1 n N i

[0043] Among them, N i Determined by the following formula:

[0044] N i =1-ε(M i )...

Embodiment 2

[0053] Such as figure 2 As shown, a method for applying the system to discretely process faulty vehicles includes:

[0054] Step 1, sending the operation signal and the failure signal to the diagnosis device through the input device and the controller;

[0055] Step 2, the diagnosis device diagnoses the operation signal and the failure signal, and obtains the verification result;

[0056] Step 3, transmitting the verification result to the server through the transmission device;

[0057] Step 4, the server organizes the verification results of several vehicles, so as to summarize the information of the discrete vehicles;

[0058] Step 5, the server sends the check result of each vehicle to the output device, and the output device displays the check result;

[0059] Step 6. The maintenance personnel monitor the verification result displayed on the output device, and maintain the faulty vehicle according to the displayed verification result.

[0060] The above method can al...

Abstract

The present invention discloses a fault diagnosis system and a method of applying the same to discretely process faulted vehicles. The system comprises an input device, a controller, a diagnostic device, a transmission device, a server and an output device. The input device, the controller and the transmission device are connected with the diagnostic device, and the server is connected with the transmission device and the output device. The method comprises the steps that the input device and the controller send a signal to the diagnostic device; the diagnostic device diagnoses the signal; the transmission device transmits to the server; the server tidies the signals of a plurality of vehicles; the server sends the signals of the vehicles to the output device; the maintenance personnel monitor the fault conditions displayed on the output device. According to the present invention, the maintenance personnel can discover the vehicle faults timely, also can manage the discrete vehicles easily, and can make the corresponding maintenance schemes at any time.

Description

technical field [0001] The invention relates to the field of vehicle maintenance, in particular to a fault diagnosis system, and also to a method for discretely processing faulty vehicles using the system. Background technique [0002] With the rapid development of the automobile industry, more and more electronic control systems are used in automobiles. However, due to the electronicization of automobiles, it is difficult to quickly diagnose automobile faults. In addition, the current user group of storage vehicles is non-professional and the level is very low. If the vehicle fails, it needs professional after-sales service personnel to deal with it. time, delays. [0003] Therefore, it is very difficult for the user to fully understand the condition of the vehicle. Therefore, a fault diagnosis system and a method for discretely processing faulty vehicles using the system are needed to quickly find faults in the vehicle. [0004] In view of the above-mentioned defects, th...
